+RCU and Unloadable Modules
+
+[Originally published in LWN Jan. 14, 2007: http://lwn.net/Articles/217484/]
+
+RCU (read-copy update) is a synchronization mechanism that can be thought
+of as a replacement for read-writer locking (among other things), but with
+very low-overhead readers that are immune to deadlock, priority inversion,
+and unbounded latency. RCU read-side critical sections are delimited
+by rcu_read_lock() and rcu_read_unlock(), which, in non-CONFIG_PREEMPT
+kernels, generate no code whatsoever.
+
+This means that RCU writers are unaware of the presence of concurrent
+readers, so that RCU updates to shared data must be undertaken quite
+carefully, leaving an old version of the data structure in place until all
+pre-existing readers have finished. These old versions are needed because
+such readers might hold a reference to them. RCU updates can therefore be
+rather expensive, and RCU is thus best suited for read-mostly situations.
+
+How can an RCU writer possibly determine when all readers are finished,
+given that readers might well leave absolutely no trace of their
+presence? There is a synchronize_rcu() primitive that blocks until all
+pre-existing readers have completed. An updater wishing to delete an
+element p from a linked list might do the following, while holding an
+appropriate lock, of course:
+
+	list_del_rcu(p);
+	synchronize_rcu();
+	kfree(p);
+
+But the above code cannot be used in IRQ context -- the call_rcu()
+primitive must be used instead. This primitive takes a pointer to an
+rcu_head struct placed within the RCU-protected data structure and
+another pointer to a function that may be invoked later to free that
+structure. Code to delete an element p from the linked list from IRQ
+context might then be as follows:
+
+	list_del_rcu(p);
+	call_rcu(&p->rcu, p_callback);
+
+Since call_rcu() never blocks, this code can safely be used from within
+IRQ context. The function p_callback() might be defined as follows:
+
+	static void p_callback(struct rcu_head *rp)
+	{
+		struct pstruct *p = container_of(rp, struct pstruct, rcu);
+
+		kfree(p);
+	}
+
+
+Unloading Modules That Use call_rcu()
+
+But what if p_callback is defined in an unloadable module?
+
+If we unload the module while some RCU callbacks are pending,
+the CPUs executing these callbacks are going to be severely
+disappointed when they are later invoked, as fancifully depicted at
+http://lwn.net/images/ns/kernel/rcu-drop.jpg.
+
+We could try placing a synchronize_rcu() in the module-exit code path,
+but this is not sufficient. Although synchronize_rcu() does wait for a
+grace period to elapse, it does not wait for the callbacks to complete.
+
+One might be tempted to try several back-to-back synchronize_rcu()
+calls, but this is still not guaranteed to work. If there is a very
+heavy RCU-callback load, then some of the callbacks might be deferred
+in order to allow other processing to proceed. Such deferral is required
+in realtime kernels in order to avoid excessive scheduling latencies.
+
+
+rcu_barrier()
+
+We instead need the rcu_barrier() primitive. This primitive is similar
+to synchronize_rcu(), but instead of waiting solely for a grace
+period to elapse, it also waits for all outstanding RCU callbacks to
+complete. Pseudo-code using rcu_barrier() is as follows:
+
+   1. Prevent any new RCU callbacks from being posted.
+   2. Execute rcu_barrier().
+   3. Allow the module to be unloaded.
+
+Quick Quiz #1: Why is there no srcu_barrier()?
+
+The rcutorture module makes use of rcu_barrier in its exit function
+as follows:
+
+ 1 static void
+ 2 rcu_torture_cleanup(void)
+ 3 {
+ 4   int i;
+ 5

+15     kthread_stop(writer_task);
+16   }
+17   writer_task = NULL;
+18
+19   if (reader_tasks != NULL) {
+20     for (i = 0; i < nrealreaders; i++) {
+21       if (reader_tasks[i] != NULL) {
+22         VERBOSE_PRINTK_STRING(
+23           "Stopping rcu_torture_reader task");
+24         kthread_stop(reader_tasks[i]);
+25       }
+26       reader_tasks[i] = NULL;
+27     }
+28     kfree(reader_tasks);
+29     reader_tasks = NULL;
+30   }
+31   rcu_torture_current = NULL;
+32
+33   if (fakewriter_tasks != NULL) {
+34     for (i = 0; i < nfakewriters; i++) {
+35       if (fakewriter_tasks[i] != NULL) {
+36         VERBOSE_PRINTK_STRING(
+37           "Stopping rcu_torture_fakewriter task");
+38         kthread_stop(fakewriter_tasks[i]);
+39       }
+40       fakewriter_tasks[i] = NULL;
+41     }
+42     kfree(fakewriter_tasks);
+43     fakewriter_tasks = NULL;
+44   }
+45
+46   if (stats_task != NULL) {
+47     VERBOSE_PRINTK_STRING("Stopping rcu_torture_stats task");
+48     kthread_stop(stats_task);
+49   }
+50   stats_task = NULL;

+58     cur_ops->cleanup();

+61   else
+62     rcu_torture_print_module_parms("End of test: SUCCESS");
+63 }
+
+Line 6 sets a global variable that prevents any RCU callbacks from
+re-posting themselves. This will not be necessary in most cases, since
+RCU callbacks rarely include calls to call_rcu(). However, the rcutorture
+module is an exception to this rule, and therefore needs to set this
+global variable.
+
+Lines 7-50 stop all the kernel tasks associated with the rcutorture
+module. Therefore, once execution reaches line 53, no more rcutorture
+RCU callbacks will be posted. The rcu_barrier() call on line 53 waits
+for any pre-existing callbacks to complete.
+
+Then lines 55-62 print status and do operation-specific cleanup, and
+then return, permitting the module-unload operation to be completed.
+
+Quick Quiz #2: Is there any other situation where rcu_barrier() might
+	be required?
+
+Your module might have additional complications. For example, if your
+module invokes call_rcu() from timers, you will need to first cancel all
+the timers, and only then invoke rcu_barrier() to wait for any remaining
+RCU callbacks to complete.
+
+
+Implementing rcu_barrier()
+
+Dipankar Sarma's implementation of rcu_barrier() makes use of the fact
+that RCU callbacks are never reordered once queued on one of the per-CPU
+queues. His implementation queues an RCU callback on each of the per-CPU
+callback queues, and then waits until they have all started executing, at
+which point, all earlier RCU callbacks are guaranteed to have completed.
+
+The original code for rcu_barrier() was as follows:
+
+ 1 void rcu_barrier(void)
+ 2 {
+ 3   BUG_ON(in_interrupt());
+ 4   /* Take cpucontrol mutex to protect against CPU hotplug */
+ 5   mutex_lock(&rcu_barrier_mutex);
+ 6   init_completion(&rcu_barrier_completion);
+ 7   atomic_set(&rcu_barrier_cpu_count, 0);
+ 8   on_each_cpu(rcu_barrier_func, NULL, 0, 1);
+ 9   wait_for_completion(&rcu_barrier_completion);
+10   mutex_unlock(&rcu_barrier_mutex);
+11 }
+
+Line 3 verifies that the caller is in process context, and lines 5 and 10
+use rcu_barrier_mutex to ensure that only one rcu_barrier() is using the
+global completion and counters at a time, which are initialized on lines
+6 and 7. Line 8 causes each CPU to invoke rcu_barrier_func(), which is
+shown below. Note that the final "1" in on_each_cpu()'s argument list
+ensures that all the calls to rcu_barrier_func() will have completed
+before on_each_cpu() returns. Line 9 then waits for the completion.
+
+This code was rewritten in 2008 to support rcu_barrier_bh() and
+rcu_barrier_sched() in addition to the original rcu_barrier().
+
+The rcu_barrier_func() runs on each CPU, where it invokes call_rcu()
+to post an RCU callback, as follows:
+
+ 1 static void rcu_barrier_func(void *notused)
+ 2 {
+ 3 int cpu = smp_processor_id();
+ 4 struct rcu_data *rdp = &per_cpu(rcu_data, cpu);
+ 5 struct rcu_head *head;
+ 6
+ 7 head = &rdp->barrier;
+ 8 atomic_inc(&rcu_barrier_cpu_count);
+ 9 call_rcu(head, rcu_barrier_callback);
+10 }
+
+Lines 3 and 4 locate RCU's internal per-CPU rcu_data structure,
+which contains the struct rcu_head that needed for the later call to
+call_rcu(). Line 7 picks up a pointer to this struct rcu_head, and line
+8 increments a global counter. This counter will later be decremented
+by the callback. Line 9 then registers the rcu_barrier_callback() on
+the current CPU's queue.
+
+The rcu_barrier_callback() function simply atomically decrements the
+rcu_barrier_cpu_count variable and finalizes the completion when it
+reaches zero, as follows:
+
+ 1 static void rcu_barrier_callback(struct rcu_head *notused)
+ 2 {
+ 3 if (atomic_dec_and_test(&rcu_barrier_cpu_count))
+ 4 complete(&rcu_barrier_completion);
+ 5 }
+
+Quick Quiz #3: What happens if CPU 0's rcu_barrier_func() executes
+	immediately (thus incrementing rcu_barrier_cpu_count to the
+	value one), but the other CPU's rcu_barrier_func() invocations
+	are delayed for a full grace period? Couldn't this result in
+	rcu_barrier() returning prematurely?
+
+
+rcu_barrier() Summary
+
+The rcu_barrier() primitive has seen relatively little use, since most
+code using RCU is in the core kernel rather than in modules. However, if
+you are using RCU from an unloadable module, you need to use rcu_barrier()
+so that your module may be safely unloaded.
+
+
+Answers to Quick Quizzes
+
+Quick Quiz #1: Why is there no srcu_barrier()?
+
+Answer: Since there is no call_srcu(), there can be no outstanding SRCU
+	callbacks. Therefore, there is no need to wait for them.
+
+Quick Quiz #2: Is there any other situation where rcu_barrier() might
+	be required?
+
+Answer: Interestingly enough, rcu_barrier() was not originally
+	implemented for module unloading. Nikita Danilov was using
+	RCU in a filesystem, which resulted in a similar situation at
+	filesystem-unmount time. Dipankar Sarma coded up rcu_barrier()
+	in response, so that Nikita could invoke it during the
+	filesystem-unmount process.
+
+	Much later, yours truly hit the RCU module-unload problem when
+	implementing rcutorture, and found that rcu_barrier() solves
+	this problem as well.
+
+Quick Quiz #3: What happens if CPU 0's rcu_barrier_func() executes
+	immediately (thus incrementing rcu_barrier_cpu_count to the
+	value one), but the other CPU's rcu_barrier_func() invocations
+	are delayed for a full grace period? Couldn't this result in
+	rcu_barrier() returning prematurely?
+
+Answer: This cannot happen. The reason is that on_each_cpu() has its last
+	argument, the wait flag, set to "1". This flag is passed through
+	to smp_call_function() and further to smp_call_function_on_cpu(),
+	causing this latter to spin until the cross-CPU invocation of
+	rcu_barrier_func() has completed. This by itself would prevent
+	a grace period from completing on non-CONFIG_PREEMPT kernels,
+	since each CPU must undergo a context switch (or other quiescent
+	state) before the grace period can complete. However, this is
+	of no use in CONFIG_PREEMPT kernels.
+
+	Therefore, on_each_cpu() disables preemption across its call
+	to smp_call_function() and also across the local call to
+	rcu_barrier_func(). This prevents the local CPU from context
+	switching, again preventing grace periods from completing. This
+	means that all CPUs have executed rcu_barrier_func() before
+	the first rcu_barrier_callback() can possibly execute, in turn
+	preventing rcu_barrier_cpu_count from prematurely reaching zero.
+
+	Currently, -rt implementations of RCU keep but a single global
+	queue for RCU callbacks, and thus do not suffer from this
+	problem. However, when the -rt RCU eventually does have per-CPU
+	callback queues, things will have to change. One simple change
+	is to add an rcu_read_lock() before line 8 of rcu_barrier()
+	and an rcu_read_unlock() after line 8 of this same function. If
+	you can think of a better change, please let me know!

+
+How to deal with bad memory e.g. reported by memtest86+ ?
+#########################################################
+
+There are three possibilities I know of:
+
+1) Reinsert/swap the memory modules
+
+2) Buy new modules (best!) or try to exchange the memory
+   if you have spare-parts
+
+3) Use BadRAM or memmap
+
+This Howto is about number 3) .
+
+
+BadRAM
+######
+BadRAM is the actively developed and available as kernel-patch
+here:  http://rick.vanrein.org/linux/badram/
+
+For more details see the BadRAM documentation.
+
+memmap
+######
+
+memmap is already in the kernel and usable as kernel-parameter at
+boot-time.  Its syntax is slightly strange and you may need to
+calculate the values by yourself!
+
+Syntax to exclude a memory area (see kernel-parameters.txt for details):
+memmap=<size>$<address>
+
+Example: memtest86+ reported here errors at address 0x18691458, 0x18698424 and
+         some others. All had 0x1869xxxx in common, so I chose a pattern of
+         0x18690000,0xffff0000.
+
+With the numbers of the example above:
+memmap=64K$0x18690000
+ or
+memmap=0x10000$0x18690000

+
+
+1. Blackfin GPIO introduction
+
+    There are many GPIO pins on Blackfin. Most of these pins are muxed to
+    multi-functions. They can be configured as peripheral, or just as GPIO,
+    configured to input with interrupt enabled, or output.
+
+    For detailed information, please see "arch/blackfin/kernel/bfin_gpio.c",
+    or the relevant HRM.
+
+
+2. Avoiding resource conflict
+
+    Followed function groups are used to avoiding resource conflict,
+    - Use the pin as peripheral,
+	int peripheral_request(unsigned short per, const char *label);
+	int peripheral_request_list(const unsigned short per[], const char *label);
+	void peripheral_free(unsigned short per);
+	void peripheral_free_list(const unsigned short per[]);
+    - Use the pin as GPIO,
+	int bfin_gpio_request(unsigned gpio, const char *label);
+	void bfin_gpio_free(unsigned gpio);
+    - Use the pin as GPIO interrupt,
+	int bfin_gpio_irq_request(unsigned gpio, const char *label);
+	void bfin_gpio_irq_free(unsigned gpio);
+
+    The request functions will record the function state for a certain pin,
+    the free functions will clear it's function state.
+    Once a pin is requested, it can't be requested again before it is freed by
+    previous caller, otherwise kernel will dump stacks, and the request
+    function fail.
+    These functions are wrapped by other functions, most of the users need not
+    care.
+
+
+3. But there are some exceptions
+    - Kernel permit the identical GPIO be requested both as GPIO and GPIO
+    interrut.
+    Some drivers, like gpio-keys, need this behavior. Kernel only print out
+    warning messages like,
+	bfin-gpio: GPIO 24 is already reserved by gpio-keys: BTN0, and you are
+configuring it as IRQ!
+
+        Note: Consider the case that, if there are two drivers need the
+	identical GPIO, one of them use it as GPIO, the other use it as
+	GPIO interrupt. This will really cause resource conflict. So if
+	there is any abnormal driver behavior, please check the bfin-gpio
+	warning messages.
+
+    - Kernel permit the identical GPIO be requested from the same driver twice.

+Memory Resource Controller(Memcg)  Implementation Memo.
+Last Updated: 2008/12/15
+Base Kernel Version: based on 2.6.28-rc8-mm.
+
+Because VM is getting complex (one of reasons is memcg...), memcg's behavior
+is complex. This is a document for memcg's internal behavior.
+Please note that implementation details can be changed.
+
+(*) Topics on API should be in Documentation/controllers/memory.txt)
+
+0. How to record usage ?
+   2 objects are used.
+
+   page_cgroup ....an object per page.
+	Allocated at boot or memory hotplug. Freed at memory hot removal.
+
+   swap_cgroup ... an entry per swp_entry.
+	Allocated at swapon(). Freed at swapoff().
+
+   The page_cgroup has USED bit and double count against a page_cgroup never
+   occurs. swap_cgroup is used only when a charged page is swapped-out.
+
+1. Charge
+
+   a page/swp_entry may be charged (usage += PAGE_SIZE) at
+
+	mem_cgroup_newpage_charge()
+	  Called at new page fault and Copy-On-Write.
+
+	mem_cgroup_try_charge_swapin()
+	  Called at do_swap_page() (page fault on swap entry) and swapoff.
+	  Followed by charge-commit-cancel protocol. (With swap accounting)
+	  At commit, a charge recorded in swap_cgroup is removed.
+
+	mem_cgroup_cache_charge()
+	  Called at add_to_page_cache()
+
+	mem_cgroup_cache_charge_swapin()
+	  Called at shmem's swapin.
+
+	mem_cgroup_prepare_migration()
+	  Called before migration. "extra" charge is done and followed by
+	  charge-commit-cancel protocol.
+	  At commit, charge against oldpage or newpage will be committed.
+
+2. Uncharge
+  a page/swp_entry may be uncharged (usage -= PAGE_SIZE) by
+
+	mem_cgroup_uncharge_page()
+	  Called when an anonymous page is fully unmapped. I.e., mapcount goes
+	  to 0. If the page is SwapCache, uncharge is delayed until
+	  mem_cgroup_uncharge_swapcache().
+
+	mem_cgroup_uncharge_cache_page()
+	  Called when a page-cache is deleted from radix-tree. If the page is
+	  SwapCache, uncharge is delayed until mem_cgroup_uncharge_swapcache().
+
+	mem_cgroup_uncharge_swapcache()
+	  Called when SwapCache is removed from radix-tree. The charge itself
+	  is moved to swap_cgroup. (If mem+swap controller is disabled, no
+	  charge to swap occurs.)
+
+	mem_cgroup_uncharge_swap()
+	  Called when swp_entry's refcnt goes down to 0. A charge against swap
+	  disappears.
+
+	mem_cgroup_end_migration(old, new)
+	At success of migration old is uncharged (if necessary), a charge
+	to new page is committed. At failure, charge to old page is committed.
+
+3. charge-commit-cancel
+	In some case, we can't know this "charge" is valid or not at charging
+	(because of races).
+	To handle such case, there are charge-commit-cancel functions.
+		mem_cgroup_try_charge_XXX
+		mem_cgroup_commit_charge_XXX
+		mem_cgroup_cancel_charge_XXX
+	these are used in swap-in and migration.
+
+	At try_charge(), there are no flags to say "this page is charged".
+	at this point, usage += PAGE_SIZE.
+
+	At commit(), the function checks the page should be charged or not
+	and set flags or avoid charging.(usage -= PAGE_SIZE)
+
+	At cancel(), simply usage -= PAGE_SIZE.
+
+Under below explanation, we assume CONFIG_MEM_RES_CTRL_SWAP=y.
+
+4. Anonymous
+	Anonymous page is newly allocated at
+		  - page fault into MAP_ANONYMOUS mapping.
+		  - Copy-On-Write.
+ 	It is charged right after it's allocated before doing any page table
+	related operations. Of course, it's uncharged when another page is used
+	for the fault address.
+
+	At freeing anonymous page (by exit() or munmap()), zap_pte() is called
+	and pages for ptes are freed one by one.(see mm/memory.c). Uncharges
+	are done at page_remove_rmap() when page_mapcount() goes down to 0.
+
+	Another page freeing is by page-reclaim (vmscan.c) and anonymous
+	pages are swapped out. In this case, the page is marked as
+	PageSwapCache(). uncharge() routine doesn't uncharge the page marked
+	as SwapCache(). It's delayed until __delete_from_swap_cache().
+
+	4.1 Swap-in.
+	At swap-in, the page is taken from swap-cache. There are 2 cases.
+
+	(a) If the SwapCache is newly allocated and read, it has no charges.
+	(b) If the SwapCache has been mapped by processes, it has been
+	    charged already.
+
+	This swap-in is one of the most complicated work. In do_swap_page(),
+	following events occur when pte is unchanged.
+
+	(1) the page (SwapCache) is looked up.
+	(2) lock_page()
+	(3) try_charge_swapin()
+	(4) reuse_swap_page() (may call delete_swap_cache())
+	(5) commit_charge_swapin()
+	(6) swap_free().
+
+	Considering following situation for example.
+
+	(A) The page has not been charged before (2) and reuse_swap_page()
+	    doesn't call delete_from_swap_cache().
+	(B) The page has not been charged before (2) and reuse_swap_page()
+	    calls delete_from_swap_cache().
+	(C) The page has been charged before (2) and reuse_swap_page() doesn't
+	    call delete_from_swap_cache().
+	(D) The page has been charged before (2) and reuse_swap_page() calls
+	    delete_from_swap_cache().
+
+	    memory.usage/memsw.usage changes to this page/swp_entry will be
+	 Case          (A)      (B)       (C)     (D)
+         Event
+       Before (2)     0/ 1     0/ 1      1/ 1    1/ 1
+          ===========================================
+          (3)        +1/+1    +1/+1     +1/+1   +1/+1
+          (4)          -       0/ 0       -     -1/ 0
+          (5)         0/-1     0/ 0     -1/-1    0/ 0
+          (6)          -       0/-1       -      0/-1
+          ===========================================
+       Result         1/ 1     1/ 1      1/ 1    1/ 1
+
+       In any cases, charges to this page should be 1/ 1.
+
+	4.2 Swap-out.
+	At swap-out, typical state transition is below.
+
+	(a) add to swap cache. (marked as SwapCache)
+	    swp_entry's refcnt += 1.
+	(b) fully unmapped.
+	    swp_entry's refcnt += # of ptes.
+	(c) write back to swap.
+	(d) delete from swap cache. (remove from SwapCache)
+	    swp_entry's refcnt -= 1.
+
+
+	At (b), the page is marked as SwapCache and not uncharged.
+	At (d), the page is removed from SwapCache and a charge in page_cgroup
+	is moved to swap_cgroup.
+
+	Finally, at task exit,
+	(e) zap_pte() is called and swp_entry's refcnt -=1 -> 0.
+	Here, a charge in swap_cgroup disappears.
+
+5. Page Cache
+   	Page Cache is charged at
+	- add_to_page_cache_locked().
+
+	uncharged at
+	- __remove_from_page_cache().
+
+	The logic is very clear. (About migration, see below)
+	Note: __remove_from_page_cache() is called by remove_from_page_cache()
+	and __remove_mapping().
+
+6. Shmem(tmpfs) Page Cache
+	Memcg's charge/uncharge have special handlers of shmem. The best way
+	to understand shmem's page state transition is to read mm/shmem.c.
+	But brief explanation of the behavior of memcg around shmem will be
+	helpful to understand the logic.
+
+	Shmem's page (just leaf page, not direct/indirect block) can be on
+		- radix-tree of shmem's inode.
+		- SwapCache.
+		- Both on radix-tree and SwapCache. This happens at swap-in
+		  and swap-out,
+
+	It's charged when...
+	- A new page is added to shmem's radix-tree.
+	- A swp page is read. (move a charge from swap_cgroup to page_cgroup)
+	It's uncharged when
+	- A page is removed from radix-tree and not SwapCache.
+	- When SwapCache is removed, a charge is moved to swap_cgroup.
+	- When swp_entry's refcnt goes down to 0, a charge in swap_cgroup
+	  disappears.
+
+7. Page Migration
+   	One of the most complicated functions is page-migration-handler.
+	Memcg has 2 routines. Assume that we are migrating a page's contents
+	from OLDPAGE to NEWPAGE.
+
+	Usual migration logic is..
+	(a) remove the page from LRU.
+	(b) allocate NEWPAGE (migration target)
+	(c) lock by lock_page().
+	(d) unmap all mappings.
+	(e-1) If necessary, replace entry in radix-tree.
+	(e-2) move contents of a page.
+	(f) map all mappings again.
+	(g) pushback the page to LRU.
+	(-) OLDPAGE will be freed.
+
+	Before (g), memcg should complete all necessary charge/uncharge to
+	NEWPAGE/OLDPAGE.
+
+	The point is....
+	- If OLDPAGE is anonymous, all charges will be dropped at (d) because
+          try_to_unmap() drops all mapcount and the page will not be
+	  SwapCache.
+
+	- If OLDPAGE is SwapCache, charges will be kept at (g) because
+	  __delete_from_swap_cache() isn't called at (e-1)
+
+	- If OLDPAGE is page-cache, charges will be kept at (g) because
+	  remove_from_swap_cache() isn't called at (e-1)
+
+	memcg provides following hooks.
+
+	- mem_cgroup_prepare_migration(OLDPAGE)
+	  Called after (b) to account a charge (usage += PAGE_SIZE) against
+	  memcg which OLDPAGE belongs to.
+
+        - mem_cgroup_end_migration(OLDPAGE, NEWPAGE)
+	  Called after (f) before (g).
+	  If OLDPAGE is used, commit OLDPAGE again. If OLDPAGE is already
+	  charged, a charge by prepare_migration() is automatically canceled.
+	  If NEWPAGE is used, commit NEWPAGE and uncharge OLDPAGE.
+
+	  But zap_pte() (by exit or munmap) can be called while migration,
+	  we have to check if OLDPAGE/NEWPAGE is a valid page after commit().
+
+8. LRU
+        Each memcg has its own private LRU. Now, it's handling is under global
+	VM's control (means that it's handled under global zone->lru_lock).
+	Almost all routines around memcg's LRU is called by global LRU's
+	list management functions under zone->lru_lock().
+
+	A special function is mem_cgroup_isolate_pages(). This scans
+	memcg's private LRU and call __isolate_lru_page() to extract a page
+	from LRU.
+	(By __isolate_lru_page(), the page is removed from both of global and
+	 private LRU.)
+
+
+9. Typical Tests.
+
+ Tests for racy cases.
+
+ 9.1 Small limit to memcg.
+	When you do test to do racy case, it's good test to set memcg's limit
+	to be very small rather than GB. Many races found in the test under
+	xKB or xxMB limits.
+	(Memory behavior under GB and Memory behavior under MB shows very
+	 different situation.)
+
+ 9.2 Shmem
+	Historically, memcg's shmem handling was poor and we saw some amount
+	of troubles here. This is because shmem is page-cache but can be
+	SwapCache. Test with shmem/tmpfs is always good test.
+
+ 9.3 Migration
+	For NUMA, migration is an another special case. To do easy test, cpuset
+	is useful. Following is a sample script to do migration.
+
+	mount -t cgroup -o cpuset none /opt/cpuset
+
+	mkdir /opt/cpuset/01
+	echo 1 > /opt/cpuset/01/cpuset.cpus
+	echo 0 > /opt/cpuset/01/cpuset.mems
+	echo 1 > /opt/cpuset/01/cpuset.memory_migrate
+	mkdir /opt/cpuset/02
+	echo 1 > /opt/cpuset/02/cpuset.cpus
+	echo 1 > /opt/cpuset/02/cpuset.mems
+	echo 1 > /opt/cpuset/02/cpuset.memory_migrate
+
+	In above set, when you moves a task from 01 to 02, page migration to
+	node 0 to node 1 will occur. Following is a script to migrate all
+	under cpuset.
+	--
+	move_task()
+	{
+	for pid in $1
+        do
+                /bin/echo $pid >$2/tasks 2>/dev/null
+		echo -n $pid
+		echo -n " "
+        done
+	echo END
+	}
+
+	G1_TASK=`cat ${G1}/tasks`
+	G2_TASK=`cat ${G2}/tasks`
+	move_task "${G1_TASK}" ${G2} &
+	--
+ 9.4 Memory hotplug.
+	memory hotplug test is one of good test.
+	to offline memory, do following.
+	# echo offline > /sys/devices/system/memory/memoryXXX/state
+	(XXX is the place of memory)
+	This is an easy way to test page migration, too.
+
+ 9.5 mkdir/rmdir
+	When using hierarchy, mkdir/rmdir test should be done.
+	Use tests like the following.
+
+	echo 1 >/opt/cgroup/01/memory/use_hierarchy
+	mkdir /opt/cgroup/01/child_a
+	mkdir /opt/cgroup/01/child_b
+
+	set limit to 01.
+	add limit to 01/child_b
+	run jobs under child_a and child_b
+
+	create/delete following groups at random while jobs are running.
+	/opt/cgroup/01/child_a/child_aa
+	/opt/cgroup/01/child_b/child_bb
+	/opt/cgroup/01/child_c
+
+	running new jobs in new group is also good.
+
+ 9.6 Mount with other subsystems.
+	Mounting with other subsystems is a good test because there is a
+	race and lock dependency with other cgroup subsystems.
+
+	example)
+	# mount -t cgroup none /cgroup -t cpuset,memory,cpu,devices
+
+	and do task move, mkdir, rmdir etc...under this.

+
+
+6. Hierarchy support
+
+The memory controller supports a deep hierarchy and hierarchical accounting.
+The hierarchy is created by creating the appropriate cgroups in the
+cgroup filesystem. Consider for example, the following cgroup filesystem
+hierarchy
+
+		root
+	     /  |   \
+           /	|    \
+	  a	b	c
+			| \
+			|  \
+			d   e
+
+In the diagram above, with hierarchical accounting enabled, all memory
+usage of e, is accounted to its ancestors up until the root (i.e, c and root),
+that has memory.use_hierarchy enabled.  If one of the ancestors goes over its
+limit, the reclaim algorithm reclaims from the tasks in the ancestor and the
+children of the ancestor.
+
+6.1 Enabling hierarchical accounting and reclaim
+
+The memory controller by default disables the hierarchy feature. Support
+can be enabled by writing 1 to memory.use_hierarchy file of the root cgroup
+
+# echo 1 > memory.use_hierarchy
+
+The feature can be disabled by
+
+# echo 0 > memory.use_hierarchy
+
+NOTE1: Enabling/disabling will fail if the cgroup already has other
+cgroups created below it.
+
+NOTE2: This feature can be enabled/disabled per subtree.

-4.2 "My application needs finer control of hardware channels"
-This requirement seems to arise from cases where a DMA engine driver is
-trying to support device-to-memory DMA.  The dmaengine and async_tx
-implementations were designed for offloading memory-to-memory
-operations; however, there are some capabilities of the dmaengine layer
-that can be used for platform-specific channel management.
-Platform-specific constraints can be handled by registering the
-application as a 'dma_client' and implementing a 'dma_event_callback' to
-apply a filter to the available channels in the system.  Before showing
-how to implement a custom dma_event callback some background of
-dmaengine's client support is required.
-
-The following routines in dmaengine support multiple clients requesting
-use of a channel:
-- dma_async_client_register(struct dma_client *client)
-- dma_async_client_chan_request(struct dma_client *client)
-
-dma_async_client_register takes a pointer to an initialized dma_client
-structure.  It expects that the 'event_callback' and 'cap_mask' fields
-are already initialized.
-
-dma_async_client_chan_request triggers dmaengine to notify the client of
-all channels that satisfy the capability mask.  It is up to the client's
-event_callback routine to track how many channels the client needs and
-how many it is currently using.  The dma_event_callback routine returns a
-dma_state_client code to let dmaengine know the status of the
-allocation.
-
-Below is the example of how to extend this functionality for
-platform-specific filtering of the available channels beyond the
-standard capability mask:
-
-static enum dma_state_client
-my_dma_client_callback(struct dma_client *client,
-			struct dma_chan *chan, enum dma_state state)
-{
-	struct dma_device *dma_dev;
-	struct my_platform_specific_dma *plat_dma_dev;
-	
-	dma_dev = chan->device;
-	plat_dma_dev = container_of(dma_dev,
-				    struct my_platform_specific_dma,
-				    dma_dev);
-
-	if (!plat_dma_dev->platform_specific_capability)
-		return DMA_DUP;
-
-	. . .
-}
+4.2 "My application needs exclusive control of hardware channels"
+Primarily this requirement arises from cases where a DMA engine driver
+is being used to support device-to-memory operations.  A channel that is
+performing these operations cannot, for many platform specific reasons,
+be shared.  For these cases the dma_request_channel() interface is
+provided.
+
+The interface is:
+struct dma_chan *dma_request_channel(dma_cap_mask_t mask,
+				     dma_filter_fn filter_fn,
+				     void *filter_param);
+
+Where dma_filter_fn is defined as:
+typedef bool (*dma_filter_fn)(struct dma_chan *chan, void *filter_param);
+
+When the optional 'filter_fn' parameter is set to NULL
+dma_request_channel simply returns the first channel that satisfies the
+capability mask.  Otherwise, when the mask parameter is insufficient for
+specifying the necessary channel, the filter_fn routine can be used to
+disposition the available channels in the system. The filter_fn routine
+is called once for each free channel in the system.  Upon seeing a
+suitable channel filter_fn returns DMA_ACK which flags that channel to
+be the return value from dma_request_channel.  A channel allocated via
+this interface is exclusive to the caller, until dma_release_channel()
+is called.
+
+The DMA_PRIVATE capability flag is used to tag dma devices that should
+not be used by the general-purpose allocator.  It can be set at
+initialization time if it is known that a channel will always be
+private.  Alternatively, it is set when dma_request_channel() finds an
+unused "public" channel.
+
+A couple caveats to note when implementing a driver and consumer:
+1/ Once a channel has been privately allocated it will no longer be
+   considered by the general-purpose allocator even after a call to
+   dma_release_channel().
+2/ Since capabilities are specified at the device level a dma_device
+   with multiple channels will either have all channels public, or all
+   channels private.

+	BTRFS
+	=====
+
+Btrfs is a new copy on write filesystem for Linux aimed at
+implementing advanced features while focusing on fault tolerance,
+repair and easy administration. Initially developed by Oracle, Btrfs
+is licensed under the GPL and open for contribution from anyone.
+
+Linux has a wealth of filesystems to choose from, but we are facing a
+number of challenges with scaling to the large storage subsystems that
+are becoming common in today's data centers. Filesystems need to scale
+in their ability to address and manage large storage, and also in
+their ability to detect, repair and tolerate errors in the data stored
+on disk.  Btrfs is under heavy development, and is not suitable for
+any uses other than benchmarking and review. The Btrfs disk format is
+not yet finalized.
+
+The main Btrfs features include:
+
+    * Extent based file storage (2^64 max file size)
+    * Space efficient packing of small files
+    * Space efficient indexed directories
+    * Dynamic inode allocation
+    * Writable snapshots
+    * Subvolumes (separate internal filesystem roots)
+    * Object level mirroring and striping
+    * Checksums on data and metadata (multiple algorithms available)
+    * Compression
+    * Integrated multiple device support, with several raid algorithms
+    * Online filesystem check (not yet implemented)
+    * Very fast offline filesystem check
+    * Efficient incremental backup and FS mirroring (not yet implemented)
+    * Online filesystem defragmentation
+
+
+
+	MAILING LIST
+	============
+
+There is a Btrfs mailing list hosted on vger.kernel.org. You can
+find details on how to subscribe here:
+
+http://vger.kernel.org/vger-lists.html#linux-btrfs

+
+Discussion of Btrfs also occurs on the #btrfs channel of the Freenode

+Description
+-----------
+
+Fintek F718xxFG/F8000 Super I/O chips include complete hardware monitoring
+capabilities. They can monitor up to 9 voltages (3 for the F8000), 4 fans and
+3 temperature sensors.
+
+These chips also have fan controlling features, using either DC or PWM, in
+three different modes (one manual, two automatic).
+
+The driver assumes that no more than one chip is present, which seems
+reasonable.
+
+
+Monitoring
+----------
+
+The Voltage, Fan and Temperature Monitoring uses the standard sysfs
+interface as documented in sysfs-interface, without any exceptions.
+
+
+Fan Control
+-----------
+
+Both PWM (pulse-width modulation) and DC fan speed control methods are
+supported. The right one to use depends on external circuitry on the
+motherboard, so the driver assumes that the BIOS set the method
+properly.
+
+There are 2 modes to specify the speed of the fan, PWM duty cycle (or DC
+voltage) mode, where 0-100% duty cycle (0-100% of 12V) is specified. And RPM
+mode where the actual RPM of the fan (as measured) is controlled and the speed
+gets specified as 0-100% of the fan#_full_speed file.
+
+Since both modes work in a 0-100% (mapped to 0-255) scale, there isn't a
+whole lot of a difference when modifying fan control settings. The only
+important difference is that in RPM mode the 0-100% controls the fan speed
+between 0-100% of fan#_full_speed. It is assumed that if the BIOS programs
+RPM mode, it will also set fan#_full_speed properly, if it does not then
+fan control will not work properly, unless you set a sane fan#_full_speed
+value yourself.
+
+Switching between these modes requires re-initializing a whole bunch of
+registers, so the mode which the BIOS has set is kept. The mode is
+printed when loading the driver.
+
+Three different fan control modes are supported; the mode number is written
+to the pwm#_enable file. Note that not all modes are supported on all
+chips, and some modes may only be available in RPM / PWM mode on the F8000.
+Writing an unsupported mode will result in an invalid parameter error.
+
+* 1: Manual mode
+  You ask for a specific PWM duty cycle / DC voltage or a specific % of
+  fan#_full_speed by writing to the pwm# file. This mode is only
+  available on the F8000 if the fan channel is in RPM mode.
+
+* 2: Normal auto mode
+  You can define a number of temperature/fan speed trip points, which % the
+  fan should run at at this temp and which temp a fan should follow using the
+  standard sysfs interface. The number and type of trip points is chip
+  depended, see which files are available in sysfs.
+  Fan/PWM channel 3 of the F8000 is always in this mode!
+
+* 3: Thermostat mode (Only available on the F8000 when in duty cycle mode)
+  The fan speed is regulated to keep the temp the fan is mapped to between
+  temp#_auto_point2_temp and temp#_auto_point3_temp.
+
+Both of the automatic modes require that pwm1 corresponds to fan1, pwm2 to
+fan2 and pwm3 to fan3.

+-----------
+
+The LTC4245 controller allows a board to be safely inserted and removed
+from a live backplane in multiple supply systems such as CompactPCI and
+PCI Express.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for LTC4245 devices, due to the fact that some
+of the possible addresses are unfriendly to probing. You will need to use
+the "force" parameter to tell the driver where to find the device.
+
+Example: the following will load the driver for an LTC4245 at address 0x23
+on I2C bus #1:
+$ modprobe ltc4245 force=1,0x23
+
+
+Sysfs entries
+-------------
+
+The LTC4245 has built-in limits for over and under current warnings. This
+makes it very likely that the reference circuit will be used.
+
+This driver uses the values in the datasheet to change the register values
+into the values specified in the sysfs-interface document. The current readings

+Binary data representations:
+
+One binary and octal value can be grouped to nibble. 24 nibbles + one binary
+values can be sampled between sync pulses.
+
+Values for first four channels (analog joystick values) can be found in
+first 10 nibbles. Analog value is represented by one sign bit and 9 bit
+absolute binary value. (10 bits per channel). Next nibble is checksum for
+first ten nibbles.
+
+Next nibbles 12 .. 21 represents four channels (not all channels can be
+directly controlled from TX). Binary representations ar the same as in first
+four channels. In nibbles 22 and 23 is a special magic number. Nibble 24 is
+checksum for nibbles 12..23.
+
+After last octal value for nibble 24 and next sync pulse one additional
+binary value can be sampled. This bit and magic number is not used in
+software driver. Some details about this magic numbers can be found in
+Walkera_Wk-0701_PCM.pdf.
+
+Checksum calculation:
+
+Summary of octal values in nibbles must be same as octal value in checksum
+nibble (only first 3 bits are used). Binary value for checksum nibble is
+calculated by sum of binary values in checked nibbles + sum of octal values
+in checked nibbles divided by 8. Only bit 0 of this sum is used.

+NOMMU mmap automatically rounds up to the nearest power-of-2 number of pages

+   Driver for the Intel Wireless Wimax Connection 2400m
+
+   (C) 2008 Intel Corporation < linux-wimax@intel.com >
+
+   This provides a driver for the Intel Wireless WiMAX Connection 2400m
+   and a basic Linux kernel WiMAX stack.
+
+1. Requirements
+
+     * Linux installation with Linux kernel 2.6.22 or newer (if building
+       from a separate tree)
+     * Intel i2400m Echo Peak or Baxter Peak; this includes the Intel
+       Wireless WiMAX/WiFi Link 5x50 series.
+     * build tools:
+          + Linux kernel development package for the target kernel; to
+            build against your currently running kernel, you need to have
+            the kernel development package corresponding to the running
+            image installed (usually if your kernel is named
+            linux-VERSION, the development package is called
+            linux-dev-VERSION or linux-headers-VERSION).
+          + GNU C Compiler, make
+
+2. Compilation and installation
+
+2.1. Compilation of the drivers included in the kernel
+
+   Configure the kernel; to enable the WiMAX drivers select Drivers >
+   Networking Drivers > WiMAX device support. Enable all of them as
+   modules (easier).
+
+   If USB or SDIO are not enabled in the kernel configuration, the options
+   to build the i2400m USB or SDIO drivers will not show. Enable said
+   subsystems and go back to the WiMAX menu to enable the drivers.
+
+   Compile and install your kernel as usual.
+
+2.2. Compilation of the drivers distributed as an standalone module
+
+   To compile
+
+$ cd source/directory
+$ make
+
+   Once built you can load and unload using the provided load.sh script;
+   load.sh will load the modules, load.sh u will unload them.
+
+   To install in the default kernel directories (and enable auto loading
+   when the device is plugged):
+
+$ make install
+$ depmod -a
+
+   If your kernel development files are located in a non standard
+   directory or if you want to build for a kernel that is not the
+   currently running one, set KDIR to the right location:
+
+$ make KDIR=/path/to/kernel/dev/tree
+
+   For more information, please contact linux-wimax@intel.com.
+
+3. Installing the firmware
+
+   The firmware can be obtained from http://linuxwimax.org or might have
+   been supplied with your hardware.
+
+   It has to be installed in the target system:
+     *
+$ cp FIRMWAREFILE.sbcf /lib/firmware/i2400m-fw-BUSTYPE-1.3.sbcf
+
+     * NOTE: if your firmware came in an .rpm or .deb file, just install
+       it as normal, with the rpm (rpm -i FIRMWARE.rpm) or dpkg
+       (dpkg -i FIRMWARE.deb) commands. No further action is needed.
+     * BUSTYPE will be usb or sdio, depending on the hardware you have.
+       Each hardware type comes with its own firmware and will not work
+       with other types.
+
+4. Design
+
+   This package contains two major parts: a WiMAX kernel stack and a
+   driver for the Intel i2400m.
+
+   The WiMAX stack is designed to provide for common WiMAX control
+   services to current and future WiMAX devices from any vendor; please
+   see README.wimax for details.
+
+   The i2400m kernel driver is broken up in two main parts: the bus
+   generic driver and the bus-specific drivers. The bus generic driver
+   forms the drivercore and contain no knowledge of the actual method we
+   use to connect to the device. The bus specific drivers are just the
+   glue to connect the bus-generic driver and the device. Currently only
+   USB and SDIO are supported. See drivers/net/wimax/i2400m/i2400m.h for
+   more information.
+
+   The bus generic driver is logically broken up in two parts: OS-glue and
+   hardware-glue. The OS-glue interfaces with Linux. The hardware-glue
+   interfaces with the device on using an interface provided by the
+   bus-specific driver. The reason for this breakup is to be able to
+   easily reuse the hardware-glue to write drivers for other OSes; note
+   the hardware glue part is written as a native Linux driver; no
+   abstraction layers are used, so to port to another OS, the Linux kernel
+   API calls should be replaced with the target OS's.
+
+5. Usage
+
+   To load the driver, follow the instructions in the install section;
+   once the driver is loaded, plug in the device (unless it is permanently
+   plugged in). The driver will enumerate the device, upload the firmware
+   and output messages in the kernel log (dmesg, /var/log/messages or
+   /var/log/kern.log) such as:
+
+...
+i2400m_usb 5-4:1.0: firmware interface version 8.0.0
+i2400m_usb 5-4:1.0: WiMAX interface wmx0 (00:1d:e1:01:94:2c) ready
+
+   At this point the device is ready to work.
+
+   Current versions require the Intel WiMAX Network Service in userspace
+   to make things work. See the network service's README for instructions
+   on how to scan, connect and disconnect.
+
+5.1. Module parameters
+
+   Module parameters can be set at kernel or module load time or by
+   echoing values:
+
+$ echo VALUE > /sys/module/MODULENAME/parameters/PARAMETERNAME
+
+   To make changes permanent, for example, for the i2400m module, you can
+   also create a file named /etc/modprobe.d/i2400m containing:
+
+options i2400m idle_mode_disabled=1
+
+   To find which parameters are supported by a module, run:
+
+$ modinfo path/to/module.ko
+
+   During kernel bootup (if the driver is linked in the kernel), specify
+   the following to the kernel command line:
+
+i2400m.PARAMETER=VALUE
+
+5.1.1. i2400m: idle_mode_disabled
+
+   The i2400m module supports a parameter to disable idle mode. This
+   parameter, once set, will take effect only when the device is
+   reinitialized by the driver (eg: following a reset or a reconnect).
+
+5.2. Debug operations: debugfs entries
+
+   The driver will register debugfs entries that allow the user to tweak
+   debug settings. There are three main container directories where
+   entries are placed, which correspond to the three blocks a i2400m WiMAX
+   driver has:
+     * /sys/kernel/debug/wimax:DEVNAME/ for the generic WiMAX stack
+       controls
+     * /sys/kernel/debug/wimax:DEVNAME/i2400m for the i2400m generic
+       driver controls
+     * /sys/kernel/debug/wimax:DEVNAME/i2400m-usb (or -sdio) for the
+       bus-specific i2400m-usb or i2400m-sdio controls).
+
+   Of course, if debugfs is mounted in a directory other than
+   /sys/kernel/debug, those paths will change.
+
+5.2.1. Increasing debug output
+
+   The files named *dl_* indicate knobs for controlling the debug output
+   of different submodules:
+     *
+# find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\*
+/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_tx
+/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_rx
+/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_notif
+/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_fw
+/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_usb
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_tx
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_rx
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_rfkill
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_netdev
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_fw
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_debugfs
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_driver
+/sys/kernel/debug/wimax:wmx0/i2400m/dl_control
+/sys/kernel/debug/wimax:wmx0/wimax_dl_stack
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_rfkill
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_reset
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_msg
+/sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
+/sys/kernel/debug/wimax:wmx0/wimax_dl_debugfs
+
+   By reading the file you can obtain the current value of said debug
+   level; by writing to it, you can set it.
+
+   To increase the debug level of, for example, the i2400m's generic TX
+   engine, just write:
+
+$ echo 3 > /sys/kernel/debug/wimax:wmx0/i2400m/dl_tx
+
+   Increasing numbers yield increasing debug information; for details of
+   what is printed and the available levels, check the source. The code
+   uses 0 for disabled and increasing values until 8.
+
+5.2.2. RX and TX statistics
+
+   The i2400m/rx_stats and i2400m/tx_stats provide statistics about the
+   data reception/delivery from the device:
+
+$ cat /sys/kernel/debug/wimax:wmx0/i2400m/rx_stats
+45 1 3 34 3104 48 480
+
+   The numbers reported are
+     * packets/RX-buffer: total, min, max
+     * RX-buffers: total RX buffers received, accumulated RX buffer size
+       in bytes, min size received, max size received
+
+   Thus, to find the average buffer size received, divide accumulated
+   RX-buffer / total RX-buffers.
+
+   To clear the statistics back to 0, write anything to the rx_stats file:
+
+$ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m_rx_stats
+
+   Likewise for TX.
+
+   Note the packets this debug file refers to are not network packet, but
+   packets in the sense of the device-specific protocol for communication
+   to the host. See drivers/net/wimax/i2400m/tx.c.
+
+5.2.3. Tracing messages received from user space
+
+   To echo messages received from user space into the trace pipe that the
+   i2400m driver creates, set the debug file i2400m/trace_msg_from_user to
+   1:
+     *
+$ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m/trace_msg_from_user
+
+5.2.4. Performing a device reset
+
+   By writing a 0, a 1 or a 2 to the file
+   /sys/kernel/debug/wimax:wmx0/reset, the driver performs a warm (without
+   disconnecting from the bus), cold (disconnecting from the bus) or bus
+   (bus specific) reset on the device.
+
+5.2.5. Asking the device to enter power saving mode
+
+   By writing any value to the /sys/kernel/debug/wimax:wmx0 file, the
+   device will attempt to enter power saving mode.
+
+6. Troubleshooting
+
+6.1. Driver complains about 'i2400m-fw-usb-1.2.sbcf: request failed'
+
+   If upon connecting the device, the following is output in the kernel
+   log:
+
+i2400m_usb 5-4:1.0: fw i2400m-fw-usb-1.3.sbcf: request failed: -2
+
+   This means that the driver cannot locate the firmware file named
+   /lib/firmware/i2400m-fw-usb-1.2.sbcf. Check that the file is present in
+   the right location.

+
+   Linux kernel WiMAX stack
+
+   (C) 2008 Intel Corporation < linux-wimax@intel.com >
+
+   This provides a basic Linux kernel WiMAX stack to provide a common
+   control API for WiMAX devices, usable from kernel and user space.
+
+1. Design
+
+   The WiMAX stack is designed to provide for common WiMAX control
+   services to current and future WiMAX devices from any vendor.
+
+   Because currently there is only one and we don't know what would be the
+   common services, the APIs it currently provides are very minimal.
+   However, it is done in such a way that it is easily extensible to
+   accommodate future requirements.
+
+   The stack works by embedding a struct wimax_dev in your device's
+   control structures. This provides a set of callbacks that the WiMAX
+   stack will call in order to implement control operations requested by
+   the user. As well, the stack provides API functions that the driver
+   calls to notify about changes of state in the device.
+
+   The stack exports the API calls needed to control the device to user
+   space using generic netlink as a marshalling mechanism. You can access
+   them using your own code or use the wrappers provided for your
+   convenience in libwimax (in the wimax-tools package).
+
+   For detailed information on the stack, please see
+   include/linux/wimax.h.
+
+2. Usage
+
+   For usage in a driver (registration, API, etc) please refer to the
+   instructions in the header file include/linux/wimax.h.
+
+   When a device is registered with the WiMAX stack, a set of debugfs
+   files will appear in /sys/kernel/debug/wimax:wmxX can tweak for
+   control.
+
+2.1. Obtaining debug information: debugfs entries
+
+   The WiMAX stack is compiled, by default, with debug messages that can
+   be used to diagnose issues. By default, said messages are disabled.
+
+   The drivers will register debugfs entries that allow the user to tweak
+   debug settings.
+
+   Each driver, when registering with the stack, will cause a debugfs
+   directory named wimax:DEVICENAME to be created; optionally, it might
+   create more subentries below it.
+
+2.1.1. Increasing debug output
+
+   The files named *dl_* indicate knobs for controlling the debug output
+   of different submodules of the WiMAX stack:
+     *
+# find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\*
+/sys/kernel/debug/wimax:wmx0/wimax_dl_stack
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_rfkill
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_reset
+/sys/kernel/debug/wimax:wmx0/wimax_dl_op_msg
+/sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
+/sys/kernel/debug/wimax:wmx0/wimax_dl_debugfs
+/sys/kernel/debug/wimax:wmx0/.... # other driver specific files
+
+       NOTE: Of course, if debugfs is mounted in a directory other than
+       /sys/kernel/debug, those paths will change.
+
+   By reading the file you can obtain the current value of said debug
+   level; by writing to it, you can set it.
+
+   To increase the debug level of, for example, the id-table submodule,
+   just write:
+
+$ echo 3 > /sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
+
+   Increasing numbers yield increasing debug information; for details of
+   what is printed and the available levels, check the source. The code
+   uses 0 for disabled and increasing values until 8.

+	  The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel.
+	  It offers versatile peripherals, such as ethernet, usb device, usb host etc.
+
+	  The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered
+	  Device (PD).
+
+	  Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is
+	  mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which
+	  will cover even the most exceptional need of memory bandwidth. Together with the onboard
+	  video decoder the board is ready for video processing.

- *
- * Returns:
- * CPLB_RELOADED	=> Successfully updated CPLB table.
- * CPLB_NO_UNLOCKED	=> All CPLBs are locked, so cannot be evicted.
- *			   This indicates that the CPLBs in the configuration

- * CPLB_PROT_VIOL	=> The address being accessed, that triggered the

+
+	We also need to add high parts from lower-level results to higher ones:
+	E[n]c = E[n] + (E[n+1]c >> 16), where E4c := E4
+
+	One interesting property is that all parts of the result that depend
+	on the sign of the multiplication are discarded.  Those would be the
+	multiplications involving R1.h and R3.h, but only the top 16 bit of
+	the 32 bit result depend on the sign, and since R1.h and R3.h only
+	occur in E1, the top half of these results is cut off.
+	So, we can just use FU mode for all of the 16-bit multiplies, and
+	ignore questions of when to use mixed mode.  */

+ *      ipv6 the relocation types R_PARISC_PCREL17F and R_PARISC_PCREL22F may
+ *      fail to reach their PLT stub if we only create one big stub array for

+ *      This reduces the distance between the PCREL location and the stub entry
+ *      so that the relocations can be fulfilled.
+ *      While calculating the final layout of the kernel module in memory, the
+ *      kernel module loader calls arch_mod_section_prepend() to request the

  *    - SEGREL32 handling

- * Note the generic OProfile stop calls do not support returning

- * calls fail on stop.	Failure to reset the debug bus is not an issue.
- * Failure to disable the SPU profiling is not an issue.  The FW calls
- * to enable the performance counters and debug bus will work even if
- * the hardware was not cleanly reset.

+/* The SPU interrupt handler
+ *
+ * SPU event profiling works as follows:
+ * The pm_signal[0] holds the one SPU event to be measured.  It is routed on
+ * the debug bus using word 0 or 1.  The value of pm_signal[1] and
+ * pm_signal[2] contain the necessary events to route the SPU program
+ * counter for the selected SPU onto the debug bus using words 2 and 3.
+ * The pm_interval register is setup to write the SPU PC value into the
+ * trace buffer at the maximum rate possible.  The trace buffer is configured
+ * to store the PCs, wrapping when it is full.  The performance counter is
+ * intialized to the max hardware count minus the number of events, N, between
+ * samples.  Once the N events have occured, a HW counter overflow occurs
+ * causing the generation of a HW counter interrupt which also stops the
+ * writing of the SPU PC values to the trace buffer.  Hence the last PC
+ * written to the trace buffer is the SPU PC that we want.  Unfortunately,
+ * we have to read from the beginning of the trace buffer to get to the
+ * last value written.  We just hope the PPU has nothing better to do then
+ * service this interrupt. The PC for the specific SPU being profiled is
+ * extracted from the trace buffer processed and stored.  The trace buffer
+ * is cleared, interrupts are cleared, the counter is reset to max - N.
+ * A kernel timer is used to periodically call the routine spu_evnt_swap()
+ * to switch to the next physical SPU in the node to profile in round robbin
+ * order.  This way data is collected for all SPUs on the node. It does mean
+ * that we need to use a relatively small value of N to ensure enough samples
+ * on each SPU are collected each SPU is being profiled 1/8 of the time.
+ * It may also be necessary to use a longer sample collection period.

-	  This driver adds support for the ACPI-WMI (Windows Management
-	  Instrumentation) mapper device (PNP0C14) found on some systems.
-
-	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
-	  ACPI firmware to userspace - this is done through various vendor
-	  defined methods and data blocks in a PNP0C14 device, which are then
-	  made available for userspace to call.
-
-	  The implementation of this in Linux currently only exposes this to
-	  other kernel space drivers.
-
-	  This driver is a required dependency to build the firmware specific
-	  drivers needed on many machines, including Acer and HP laptops.
-
-	  It is safe to enable this driver even if your DSDT doesn't define
-	  any ACPI-WMI devices.

-          This driver provides support for extra features of ACPI-compatible
-          ASUS laptops. As some of Medion laptops are made by ASUS, it may also
-          support some Medion laptops (such as 9675 for example).  It makes all
-          the extra buttons generate standard ACPI events that go through
-          /proc/acpi/events, and (on some models) adds support for changing the
-          display brightness and output, switching the LCD backlight on and off,
-          and most importantly, allows you to blink those fancy LEDs intended
-          for reporting mail and wireless status.
-
-	  Note: display switching code is currently considered EXPERIMENTAL,
-	  toying with these values may even lock your machine.
-
-          All settings are changed via /proc/acpi/asus directory entries. Owner
-          and group for these entries can be set with asus_uid and asus_gid
-          parameters.
-
-          More information and a userspace daemon for handling the extra buttons
-          at <http://sourceforge.net/projects/acpi4asus/>.
-
-          If you have an ACPI-compatible ASUS laptop, say Y or M here. This
-          driver is still under development, so if your laptop is unsupported or
-          something works not quite as expected, please use the mailing list
-          available on the above page (acpi4asus-user@lists.sourceforge.net).
-

-	---help---
-	  This driver adds support for access to certain system settings
-	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
-	  their lack of a BIOS setup menu and APM support.
-
-	  On these machines, all system configuration is handled through the
-	  ACPI.  This driver is required for access to controls not covered
-	  by the general ACPI drivers, such as LCD brightness, video output,
-	  etc.
-
-	  This driver differs from the non-ACPI Toshiba laptop driver (located
-	  under "Processor type and features") in several aspects.
-	  Configuration is accessed by reading and writing text files in the
-	  /proc tree instead of by program interface to /dev.  Furthermore, no
-	  power management functions are exposed, as those are handled by the
-	  general ACPI drivers.
-
-	  More information about this driver is available at
-	  <http://memebeam.org/toys/ToshibaAcpiDriver>.
-
-	  If you have a legacy free Toshiba laptop (such as the Libretto L1
-	  series), say Y.

+ *
+ * A subsystem can get access to a channel by calling dmaengine_get() followed

  *
  * Each device has a channels list, which runs unlocked but is never modified

  *
- * Each client is responsible for keeping track of the channels it uses.  See
- * the definition of dma_event_callback in dmaengine.h.
- *
- * Each device has a kref, which is initialized to 1 when the device is
- * registered. A kref_get is done for each device registered.  When the
- * device is released, the corresponding kref_put is done in the release
- * method. Every time one of the device's channels is allocated to a client,
- * a kref_get occurs.  When the channel is freed, the corresponding kref_put
- * happens. The device's release function does a completion, so
- * unregister_device does a remove event, device_unregister, a kref_put
- * for the first reference, then waits on the completion for all other
- * references to finish.
- *
- * Each channel has an open-coded implementation of Rusty Russell's "bigref,"
- * with a kref and a per_cpu local_t.  A dma_chan_get is called when a client
- * signals that it wants to use a channel, and dma_chan_put is called when
- * a channel is removed or a client using it is unregistered.  A client can

- * the NET DMA client.  The release function does a kref_put on the device.

- * Issue a new request to a drive from hwgroup
- *
- * A hwgroup is a serialized group of IDE interfaces.  Usually there is
- * exactly one hwif (interface) per hwgroup, but buggy controllers (eg. CMD640)
- * may have both interfaces in a single hwgroup to "serialize" access.
- * Or possibly multiple ISA interfaces can share a common IRQ by being grouped
- * together into one hwgroup for serialized access.
- *
- * Note also that several hwgroups can end up sharing a single IRQ,
- * possibly along with many other devices.  This is especially common in
- * PCI-based systems with off-board IDE controller cards.
- *
- * The IDE driver uses a per-hwgroup lock to protect the hwgroup->busy flag.
- *
- * The first thread into the driver for a particular hwgroup sets the
- * hwgroup->busy flag to indicate that this hwgroup is now active,
- * and then initiates processing of the top request from the request queue.
- *
- * Other threads attempting entry notice the busy setting, and will simply
- * queue their new requests and exit immediately.  Note that hwgroup->busy
- * remains set even when the driver is merely awaiting the next interrupt.
- * Thus, the meaning is "this hwgroup is busy processing a request".
- *
- * When processing of a request completes, the completing thread or IRQ-handler
- * will start the next request from the queue.  If no more work remains,
- * the driver will clear the hwgroup->busy flag and exit.
- *
- * The per-hwgroup spinlock is used to protect all access to the
- * hwgroup->busy flag, but is otherwise not needed for most processing in
- * the driver.  This makes the driver much more friendlier to shared IRQs
- * than previous designs, while remaining 100% (?) SMP safe and capable.

+ * i2400m_queue_work - schedule work on a i2400m's queue

+ * @i2400m: device descriptor
+ *
+ * @fn: function to run to execute work. It gets passed a 'struct
+ *     work_struct' that is wrapped in a 'struct i2400m_work'. Once
+ *     done, you have to (1) i2400m_put(i2400m_work->i2400m) and then
+ *     (2) kfree(i2400m_work).
+ *
+ * @gfp_flags: GFP flags for memory allocation.
+ *
+ * @pl: pointer to a payload buffer that you want to pass to the _work
+ *     function. Use this to pack (for example) a struct with extra
+ *     arguments.
+ *
+ * @pl_size: size of the payload buffer.
+ *
+ * We do this quite often, so this just saves typing; allocate a
+ * wrapper for a i2400m, get a ref to it, pack arguments and launch
+ * the work.
+ *
+ * A usual workflow is:
+ *
+ * struct my_work_args {
+ *         void *something;
+ *         int whatever;
+ * };
+ * ...
+ *
+ * struct my_work_args my_args = {

+ * };
+ * i2400m_queue_work(i2400m, 1, my_work_function, GFP_KERNEL,
+ *                   &args, sizeof(args))
+ *
+ * And now the work function can unpack the arguments and call the
+ * real function (or do the job itself):
+ *
+ * static
+ * void my_work_fn((struct work_struct *ws)
+ * {
+ *         struct i2400m_work *iw =

+ *  - Initial implementation
+ *
+ *
+ * THE PROCEDURE
+ *
+ * (this is decribed for USB, but for SDIO is similar)
+ *
+ * The 2400m works in two modes: boot-mode or normal mode. In boot
+ * mode we can execute only a handful of commands targeted at
+ * uploading the firmware and launching it.
+ *
+ * The 2400m enters boot mode when it is first connected to the
+ * system, when it crashes and when you ask it to reboot. There are
+ * two submodes of the boot mode: signed and non-signed. Signed takes
+ * firmwares signed with a certain private key, non-signed takes any
+ * firmware. Normal hardware takes only signed firmware.
+ *
+ * Upon entrance to boot mode, the device sends a few zero length
+ * packets (ZLPs) on the notification endpoint, then a reboot barker
+ * (4 le32 words with value I2400M_{S,N}BOOT_BARKER). We ack it by
+ * sending the same barker on the bulk out endpoint. The device acks
+ * with a reboot ack barker (4 le32 words with value 0xfeedbabe) and
+ * then the device is fully rebooted. At this point we can upload the
+ * firmware.
+ *
+ * This process is accomplished by the i2400m_bootrom_init()
+ * function. All the device interaction happens through the
+ * i2400m_bm_cmd() [boot mode command]. Special return values will
+ * indicate if the device resets.
+ *
+ * After this, we read the MAC address and then (if needed)
+ * reinitialize the device. We need to read it ahead of time because
+ * in the future, we might not upload the firmware until userspace
+ * 'ifconfig up's the device.
+ *
+ * We can then upload the firmware file. The file is composed of a BCF
+ * header (basic data, keys and signatures) and a list of write
+ * commands and payloads. We first upload the header
+ * [i2400m_dnload_init()] and then pass the commands and payloads
+ * verbatim to the i2400m_bm_cmd() function
+ * [i2400m_dnload_bcf()]. Then we tell the device to jump to the new
+ * firmware [i2400m_dnload_finalize()].
+ *
+ * Once firmware is uploaded, we are good to go :)
+ *
+ * When we don't know in which mode we are, we first try by sending a
+ * warm reset request that will take us to boot-mode. If we time out
+ * waiting for a reboot barker, that means maybe we are already in
+ * boot mode, so we send a reboot barker.
+ *
+ * COMMAND EXECUTION
+ *
+ * This code (and process) is single threaded; for executing commands,
+ * we post a URB to the notification endpoint, post the command, wait
+ * for data on the notification buffer. We don't need to worry about
+ * others as we know we are the only ones in there.
+ *
+ * BACKEND IMPLEMENTATION
+ *
+ * This code is bus-generic; the bus-specific driver provides back end
+ * implementations to send a boot mode command to the device and to
+ * read an acknolwedgement from it (or an asynchronous notification)
+ * from it.

+ *  - Initial implementation
+ *
+ *
+ * GENERAL DRIVER ARCHITECTURE
+ *
+ * The i2400m driver is split in the following two major parts:
+ *
+ *  - bus specific driver
+ *  - bus generic driver (this part)
+ *
+ * The bus specific driver sets up stuff specific to the bus the
+ * device is connected to (USB, SDIO, PCI, tam-tam...non-authoritative
+ * nor binding list) which is basically the device-model management
+ * (probe/disconnect, etc), moving data from device to kernel and
+ * back, doing the power saving details and reseting the device.
+ *
+ * For details on each bus-specific driver, see it's include file,
+ * i2400m-BUSNAME.h
+ *
+ * The bus-generic functionality break up is:
+ *
+ *  - Firmware upload: fw.c - takes care of uploading firmware to the
+ *        device. bus-specific driver just needs to provides a way to
+ *        execute boot-mode commands and to reset the device.
+ *
+ *  - RX handling: rx.c - receives data from the bus-specific code and
+ *        feeds it to the network or WiMAX stack or uses it to modify
+ *        the driver state. bus-specific driver only has to receive
+ *        frames and pass them to this module.
+ *
+ *  - TX handling: tx.c - manages the TX FIFO queue and provides means
+ *        for the bus-specific TX code to pull data from the FIFO
+ *        queue. bus-specific code just pulls frames from this module
+ *        to sends them to the device.
+ *
+ *  - netdev glue: netdev.c - interface with Linux networking
+ *        stack. Pass around data frames, and configure when the
+ *        device is up and running or shutdown (through ifconfig up /
+ *        down). Bus-generic only.
+ *
+ *  - control ops: control.c - implements various commmands for
+ *        controlling the device. bus-generic only.
+ *
+ *  - device model glue: driver.c - implements helpers for the
+ *        device-model glue done by the bus-specific layer
+ *        (setup/release the driver resources), turning the device on
+ *        and off, handling the device reboots/resets and a few simple
+ *        WiMAX stack ops.
+ *
+ * Code is also broken up in linux-glue / device-glue.
+ *
+ * Linux glue contains functions that deal mostly with gluing with the
+ * rest of the Linux kernel.
+ *
+ * Device-glue are functions that deal mostly with the way the device
+ * does things and talk the device's language.
+ *
+ * device-glue code is licensed BSD so other open source OSes can take
+ * it to implement their drivers.
+ *
+ *
+ * APIs AND HEADER FILES
+ *
+ * This bus generic code exports three APIs:
+ *
+ *  - HDI (host-device interface) definitions common to all busses
+ *    (include/linux/wimax/i2400m.h); these can be also used by user
+ *    space code.
+ *  - internal API for the bus-generic code
+ *  - external API for the bus-specific drivers
+ *
+ *
+ * LIFE CYCLE:
+ *
+ * When the bus-specific driver probes, it allocates a network device
+ * with enough space for it's data structue, that must contain a
+ * &struct i2400m at the top.
+ *
+ * On probe, it needs to fill the i2400m members marked as [fill], as
+ * well as i2400m->wimax_dev.net_dev and call i2400m_setup(). The
+ * i2400m driver will only register with the WiMAX and network stacks;
+ * the only access done to the device is to read the MAC address so we
+ * can register a network device. This calls i2400m_dev_start() to
+ * load firmware, setup communication with the device and configure it
+ * for operation.
+ *
+ * At this point, control and data communications are possible.
+ *
+ * On disconnect/driver unload, the bus-specific disconnect function
+ * calls i2400m_release() to undo i2400m_setup(). i2400m_dev_stop()
+ * shuts the firmware down and releases resources uses to communicate
+ * with the device.
+ *
+ * While the device is up, it might reset. The bus-specific driver has
+ * to catch that situation and call i2400m_dev_reset_handle() to deal
+ * with it (reset the internal driver structures and go back to square
+ * one).

+ *
+ * Members marked with [fill] must be filled out/initialized before
+ * calling i2400m_setup().
+ *
+ * @bus_tx_block_size: [fill] SDIO imposes a 256 block size, USB 16,
+ *     so we have a tx_blk_size variable that the bus layer sets to
+ *     tell the engine how much of that we need.
+ *
+ * @bus_pl_size_max: [fill] Maximum payload size.
+ *
+ * @bus_dev_start: [fill] Function called by the bus-generic code
+ *     [i2400m_dev_start()] to setup the bus-specific communications
+ *     to the the device. See LIFE CYCLE above.
+ *
+ *     NOTE: Doesn't need to upload the firmware, as that is taken
+ *     care of by the bus-generic code.
+ *
+ * @bus_dev_stop: [fill] Function called by the bus-generic code
+ *     [i2400m_dev_stop()] to shutdown the bus-specific communications
+ *     to the the device. See LIFE CYCLE above.
+ *
+ *     This function does not need to reset the device, just tear down
+ *     all the host resources created to  handle communication with
+ *     the device.
+ *
+ * @bus_tx_kick: [fill] Function called by the bus-generic code to let
+ *     the bus-specific code know that there is data available in the
+ *     TX FIFO for transmission to the device.
+ *
+ *     This function cannot sleep.
+ *
+ * @bus_reset: [fill] Function called by the bus-generic code to reset
+ *     the device in in various ways. Doesn't need to wait for the
+ *     reset to finish.
+ *
+ *     If warm or cold reset fail, this function is expected to do a
+ *     bus-specific reset (eg: USB reset) to get the device to a
+ *     working state (even if it implies device disconecction).
+ *
+ *     Note the warm reset is used by the firmware uploader to
+ *     reinitialize the device.
+ *
+ *     IMPORTANT: this is called very early in the device setup
+ *     process, so it cannot rely on common infrastructure being laid
+ *     out.
+ *
+ * @bus_bm_cmd_send: [fill] Function called to send a boot-mode
+ *     command. Flags are defined in 'enum i2400m_bm_cmd_flags'. This
+ *     is synchronous and has to return 0 if ok or < 0 errno code in
+ *     any error condition.
+ *
+ * @bus_bm_wait_for_ack: [fill] Function called to wait for a
+ *     boot-mode notification (that can be a response to a previously
+ *     issued command or an asynchronous one). Will read until all the
+ *     indicated size is read or timeout. Reading more or less data
+ *     than asked for is an error condition. Return 0 if ok, < 0 errno
+ *     code on error.
+ *
+ *     The caller to this function will check if the response is a
+ *     barker that indicates the device going into reset mode.
+ *
+ * @bus_fw_name: [fill] name of the firmware image (in most cases,
+ *     they are all the same for a single release, except that they
+ *     have the type of the bus embedded in the name (eg:
+ *     i2400m-fw-X-VERSION.sbcf, where X is the bus name).
+ *
+ * @bus_bm_mac_addr_impaired: [fill] Set to true if the device's MAC
+ *     address provided in boot mode is kind of broken and needs to
+ *     be re-read later on.
+ *
+ *
+ * @wimax_dev: WiMAX generic device for linkage into the kernel WiMAX
+ *     stack. Due to the way a net_device is allocated, we need to
+ *     force this to be the first field so that we can get from
+ *     netdev_priv() the right pointer.
+ *
+ * @state: device's state (as reported by it)
+ *
+ * @state_wq: waitqueue that is woken up whenever the state changes
+ *
+ * @tx_lock: spinlock to protect TX members
+ *
+ * @tx_buf: FIFO buffer for TX; we queue data here
+ *
+ * @tx_in: FIFO index for incoming data. Note this doesn't wrap around
+ *     and it is always greater than @tx_out.
+ *
+ * @tx_out: FIFO index for outgoing data
+ *
+ * @tx_msg: current TX message that is active in the FIFO for
+ *     appending payloads.
+ *
+ * @tx_sequence: current sequence number for TX messages from the
+ *     device to the host.
+ *
+ * @tx_msg_size: size of the current message being transmitted by the
+ *     bus-specific code.
+ *
+ * @tx_pl_num: total number of payloads sent
+ *
+ * @tx_pl_max: maximum number of payloads sent in a TX message
+ *
+ * @tx_pl_min: minimum number of payloads sent in a TX message
+ *
+ * @tx_num: number of TX messages sent
+ *
+ * @tx_size_acc: number of bytes in all TX messages sent
+ *     (this is different to net_dev's statistics as it also counts
+ *     control messages).
+ *
+ * @tx_size_min: smallest TX message sent.
+ *
+ * @tx_size_max: biggest TX message sent.
+ *
+ * @rx_lock: spinlock to protect RX members
+ *
+ * @rx_pl_num: total number of payloads received
+ *
+ * @rx_pl_max: maximum number of payloads received in a RX message
+ *
+ * @rx_pl_min: minimum number of payloads received in a RX message
+ *
+ * @rx_num: number of RX messages received
+ *
+ * @rx_size_acc: number of bytes in all RX messages received
+ *     (this is different to net_dev's statistics as it also counts
+ *     control messages).
+ *
+ * @rx_size_min: smallest RX message received.
+ *
+ * @rx_size_max: buggest RX message received.
+ *
+ * @init_mutex: Mutex used for serializing the device bringup
+ *     sequence; this way if the device reboots in the middle, we
+ *     don't try to do a bringup again while we are tearing down the
+ *     one that failed.
+ *
+ *     Can't reuse @msg_mutex because from within the bringup sequence
+ *     we need to send messages to the device and thus use @msg_mutex.
+ *
+ * @msg_mutex: mutex used to send control commands to the device (we
+ *     only allow one at a time, per host-device interface design).
+ *
+ * @msg_completion: used to wait for an ack to a control command sent
+ *     to the device.
+ *
+ * @ack_skb: used to store the actual ack to a control command if the
+ *     reception of the command was successful. Otherwise, a ERR_PTR()
+ *     errno code that indicates what failed with the ack reception.
+ *
+ *     Only valid after @msg_completion is woken up. Only updateable
+ *     if @msg_completion is armed. Only touched by
+ *     i2400m_msg_to_dev().
+ *
+ *     Protected by @rx_lock. In theory the command execution flow is
+ *     sequential, but in case the device sends an out-of-phase or
+ *     very delayed response, we need to avoid it trampling current
+ *     execution.
+ *
+ * @bm_cmd_buf: boot mode command buffer for composing firmware upload
+ *     commands.
+ *
+ *     USB can't r/w to stack, vmalloc, etc...as well, we end up
+ *     having to alloc/free a lot to compose commands, so we use these
+ *     for stagging and not having to realloc all the time.
+ *
+ *     This assumes the code always runs serialized. Only one thread
+ *     can call i2400m_bm_cmd() at the same time.
+ *
+ * @bm_ack_buf: boot mode acknoledge buffer for staging reception of
+ *     responses to commands.
+ *
+ *     See @bm_cmd_buf.
+ *
+ * @work_queue: work queue for processing device reports. This
+ *     workqueue cannot be used for processing TX or RX to the device,
+ *     as from it we'll process device reports, which might require
+ *     further communication with the device.
+ *
+ * @debugfs_dentry: hookup for debugfs files.
+ *     These have to be in a separate directory, a child of
+ *     (wimax_dev->debugfs_dentry) so they can be removed when the
+ *     module unloads, as we don't keep each dentry.

+ * This implements an ethernet device for the i2400m.
+ *
+ * We fake being an ethernet device to simplify the support from user
+ * space and from the other side. The world is (sadly) configured to
+ * take in only Ethernet devices...
+ *
+ * Because of this, currently there is an copy-each-rxed-packet
+ * overhead on the RX path. Each IP packet has to be reallocated to
+ * add an ethernet header (as there is no space in what we get from
+ * the device). This is a known drawback and coming versions of the
+ * device's firmware are being changed to add header space that can be
+ * used to insert the ethernet header without having to reallocate and
+ * copy.
+ *
+ * TX error handling is tricky; because we have to FIFO/queue the
+ * buffers for transmission (as the hardware likes it aggregated), we
+ * just give the skb to the TX subsystem and by the time it is
+ * transmitted, we have long forgotten about it. So we just don't care
+ * too much about it.
+ *
+ * Note that when the device is in idle mode with the basestation, we
+ * need to negotiate coming back up online. That involves negotiation
+ * and possible user space interaction. Thus, we defer to a workqueue
+ * to do all that. By default, we only queue a single packet and drop
+ * the rest, as potentially the time to go back from idle to normal is
+ * long.

+ * @payload: pointer to message
+ * @size: size of the message
+ *
+ * There are two types of control RX messages: reports (asynchronous,
+ * like your every day interrupts) and 'acks' (reponses to a command,
+ * get or set request).
+ *
+ * If it is a report, we run hooks on it (to extract information for
+ * things we need to do in the driver) and then pass it over to the
+ * WiMAX stack to send it to user space.
+ *
+ * NOTE: report processing is done in a workqueue specific to the
+ *     generic driver, to avoid deadlocks in the system.
+ *
+ * If it is not a report, it is an ack to a previously executed
+ * command, set or get, so wake up whoever is waiting for it from
+ * i2400m_msg_to_dev(). i2400m_rx_ctl_ack() takes care of that.
+ *
+ * Note that the sizes we pass to other functions from here are the
+ * sizes of the _l3l4_hdr + payload, not full buffer sizes, as we have
+ * verified in _msg_size_check() that they are congruent.
+ *
+ * For reports: We can't clone the original skb where the data is
+ * because we need to send this up via netlink; netlink has to add
+ * headers and we can't overwrite what's preceeding the payload...as
+ * it is another message. So we just dup them.

+ *  - Initial implementation
+ *
+ * Intel Corporation <linux-wimax@intel.com>
+ * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
+ *  - Rewritten to use a single FIFO to lower the memory allocation
+ *    pressure and optimize cache hits when copying to the queue, as
+ *    well as splitting out bus-specific code.
+ *
+ *
+ * Implements data transmission to the device; this is done through a
+ * software FIFO, as data/control frames can be coalesced (while the
+ * device is reading the previous tx transaction, others accumulate).
+ *
+ * A FIFO is used because at the end it is resource-cheaper that trying
+ * to implement scatter/gather over USB. As well, most traffic is going
+ * to be download (vs upload).
+ *
+ * The format for sending/receiving data to/from the i2400m is
+ * described in detail in rx.c:PROTOCOL FORMAT. In here we implement
+ * the transmission of that. This is split between a bus-independent
+ * part that just prepares everything and a bus-specific part that
+ * does the actual transmission over the bus to the device (in the
+ * bus-specific driver).
+ *
+ *
+ * The general format of a device-host transaction is MSG-HDR, PLD1,
+ * PLD2...PLDN, PL1, PL2,...PLN, PADDING.
+ *
+ * Because we need the send payload descriptors and then payloads and
+ * because it is kind of expensive to do scatterlists in USB (one URB
+ * per node), it becomes cheaper to append all the data to a FIFO
+ * (copying to a FIFO potentially in cache is cheaper).
+ *
+ * Then the bus-specific code takes the parts of that FIFO that are
+ * written and passes them to the device.
+ *
+ * So the concepts to keep in mind there are:
+ *
+ * We use a FIFO to queue the data in a linear buffer. We first append
+ * a MSG-HDR, space for I2400M_TX_PLD_MAX payload descriptors and then
+ * go appending payloads until we run out of space or of payload
+ * descriptors. Then we append padding to make the whole transaction a
+ * multiple of i2400m->bus_tx_block_size (as defined by the bus layer).
+ *
+ * - A TX message: a combination of a message header, payload
+ *   descriptors and payloads.
+ *
+ *     Open: it is marked as active (i2400m->tx_msg is valid) and we
+ *       can keep adding payloads to it.
+ *
+ *     Closed: we are not appending more payloads to this TX message
+ *       (exahusted space in the queue, too many payloads or
+ *       whichever).  We have appended padding so the whole message
+ *       length is aligned to i2400m->bus_tx_block_size (as set by the
+ *       bus/transport layer).
+ *
+ * - Most of the time we keep a TX message open to which we append
+ *   payloads.
+ *
+ * - If we are going to append and there is no more space (we are at
+ *   the end of the FIFO), we close the message, mark the rest of the
+ *   FIFO space unusable (skip_tail), create a new message at the
+ *   beginning of the FIFO (if there is space) and append the message
+ *   there.
+ *
+ *   This is because we need to give linear TX messages to the bus
+ *   engine. So we don't write a message to the remaining FIFO space
+ *   until the tail and continue at the head of it.
+ *
+ * - We overload one of the fields in the message header to use it as
+ *   'size' of the TX message, so we can iterate over them. It also
+ *   contains a flag that indicates if we have to skip it or not.
+ *   When we send the buffer, we update that to its real on-the-wire
+ *   value.
+ *
+ * - The MSG-HDR PLD1...PLD2 stuff has to be a size multiple of 16.
+ *
+ *   It follows that if MSG-HDR says we have N messages, the whole
+ *   header + descriptors is 16 + 4*N; for those to be a multiple of
+ *   16, it follows that N can be 4, 8, 12, ... (32, 48, 64, 80...
+ *   bytes).
+ *
+ *   So if we have only 1 payload, we have to submit a header that in
+ *   all truth has space for 4.
+ *
+ *   The implication is that we reserve space for 12 (64 bytes); but
+ *   if we fill up only (eg) 2, our header becomes 32 bytes only. So
+ *   the TX engine has to shift those 32 bytes of msg header and 2
+ *   payloads and padding so that right after it the payloads start
+ *   and the TX engine has to know about that.
+ *
+ *   It is cheaper to move the header up than the whole payloads down.
+ *
+ *   We do this in i2400m_tx_close(). See 'i2400m_msg_hdr->offset'.
+ *
+ * - Each payload has to be size-padded to 16 bytes; before appending
+ *   it, we just do it.
+ *
+ * - The whole message has to be padded to i2400m->bus_tx_block_size;
+ *   we do this at close time. Thus, when reserving space for the
+ *   payload, we always make sure there is also free space for this
+ *   padding that sooner or later will happen.
+ *
+ * When we append a message, we tell the bus specific code to kick in
+ * TXs. It will TX (in parallel) until the buffer is exhausted--hence
+ * the lockin we do. The TX code will only send a TX message at the
+ * time (which remember, might contain more than one payload). Of
+ * course, when the bus-specific driver attempts to TX a message that
+ * is still open, it gets closed first.
+ *
+ * Gee, this is messy; well a picture. In the example below we have a
+ * partially full FIFO, with a closed message ready to be delivered
+ * (with a moved message header to make sure it is size-aligned to
+ * 16), TAIL room that was unusable (and thus is marked with a message
+ * header that says 'skip this') and at the head of the buffer, an
+ * imcomplete message with a couple of payloads.

+ * A write URB is posted with the buffer to the bulk output endpoint.

+ * ACK RECEPTION
+ *
+ * We just post a URB to the notification endpoint and wait for

+ *
+ *
+ * This handles the RX path on USB.
+ *
+ * When a notification is received that says 'there is RX data ready',

+ * reads a buffer from USB and passes it to i2400m_rx() in the generic
+ * handling code. The RX buffer has an specific format that is
+ * described in rx.c.
+ *
+ * We use a kernel thread in a loop because:
+ *
+ *  - we want to be able to call the USB power management get/put
+ *    functions (blocking) before each transaction.
+ *
+ *  - We might get a lot of notifications and we don't want to submit
+ *    a zillion reads; by serializing, we are throttling.
+ *
+ *  - RX data processing can get heavy enough so that it is not
+ *    appropiate for doing it in the USB callback; thus we run it in a
+ *    process context.
+ *
+ * We provide a read buffer of an arbitrary size (short of a page); if
+ * the callback reports -EOVERFLOW, it means it was too small, so we
+ * just double the size and retry (being careful to append, as
+ * sometimes the device provided some data). Every now and then we
+ * check if the average packet size is smaller than the current packet
+ * size and if so, we halve it. At the end, the size of the

+	  This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
+	  support for Fn-Fx key combinations, Bluetooth control, video
+	  output switching, ThinkLight control, UltraBay eject and more.
+	  For more information about this driver see
+	  <file:Documentation/laptops/thinkpad-acpi.txt> and
+	  <http://ibm-acpi.sf.net/> .
+
+	  This driver was formerly known as ibm-acpi.
+

+
+config THINKPAD_ACPI_DEBUG

+
+config THINKPAD_ACPI_DOCK

+	default n
+	---help---
+	  Allows the thinkpad_acpi driver to handle docking station events.
+	  This support was made obsolete by the generic ACPI docking station
+	  support (CONFIG_ACPI_DOCK).  It will allow locking and removing the
+	  laptop from the docking station, but will not properly connect PCI
+	  devices.
+
+	  If you are not sure, say N here.
+
+config THINKPAD_ACPI_BAY
+	bool "Legacy Removable Bay Support"
+	depends on THINKPAD_ACPI
+	default y
+	---help---
+	  Allows the thinkpad_acpi driver to handle removable bays.  It will
+	  electrically disable the device in the bay, and also generate
+	  notifications when the bay lever is ejected or inserted.
+
+	  If you are not sure, say Y here.
+
+config THINKPAD_ACPI_VIDEO
+	bool "Video output control support"
+	depends on THINKPAD_ACPI
+	default y
+	---help---
+	  Allows the thinkpad_acpi driver to provide an interface to control
+	  the various video output ports.
+
+	  This feature often won't work well, depending on ThinkPad model,
+	  display state, video output devices in use, whether there is a X
+	  server running, phase of the moon, and the current mood of
+	  Schroedinger's cat.  If you can use X.org's RandR to control
+	  your ThinkPad's video output ports instead of this feature,
+	  don't think twice: do it and say N here to save some memory.
+
+	  If you are not sure, say Y here.
+
+config THINKPAD_ACPI_HOTKEY_POLL
+	bool "Support NVRAM polling for hot keys"
+	depends on THINKPAD_ACPI
+	default y
+	---help---
+	  Some thinkpad models benefit from NVRAM polling to detect a few of
+	  the hot key press events.  If you know your ThinkPad model does not
+	  need to do NVRAM polling to support any of the hot keys you use,
+	  unselecting this option will save about 1kB of memory.
+
+	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
+	  unlikely to need NVRAM polling in their latest BIOS versions.
+
+	  NVRAM polling can detect at most the following keys: ThinkPad/Access
+	  IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
+	  Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
+
+	  If you are not sure, say Y here.  The driver enables polling only if
+	  it is strictly necessary to do so.

+	  It also adds the ability to switch camera/wlan on/off.
+
+	  If you have an Eee PC laptop, say Y or M here.
+
+
+config ACPI_WMI
+	tristate "WMI (EXPERIMENTAL)"
+	depends on ACPI
+	depends on EXPERIMENTAL
+	help
+	  This driver adds support for the ACPI-WMI (Windows Management
+	  Instrumentation) mapper device (PNP0C14) found on some systems.
+
+	  ACPI-WMI is a proprietary extension to ACPI to expose parts of the
+	  ACPI firmware to userspace - this is done through various vendor
+	  defined methods and data blocks in a PNP0C14 device, which are then
+	  made available for userspace to call.
+
+	  The implementation of this in Linux currently only exposes this to
+	  other kernel space drivers.
+
+	  This driver is a required dependency to build the firmware specific
+	  drivers needed on many machines, including Acer and HP laptops.
+
+	  It is safe to enable this driver even if your DSDT doesn't define
+	  any ACPI-WMI devices.
+
+config ACPI_ASUS
+	tristate "ASUS/Medion Laptop Extras"
+	depends on ACPI
+	select BACKLIGHT_CLASS_DEVICE
+	---help---
+	  This driver provides support for extra features of ACPI-compatible
+	  ASUS laptops. As some of Medion laptops are made by ASUS, it may also
+	  support some Medion laptops (such as 9675 for example).  It makes all
+	  the extra buttons generate standard ACPI events that go through
+	  /proc/acpi/events, and (on some models) adds support for changing the
+	  display brightness and output, switching the LCD backlight on and off,
+	  and most importantly, allows you to blink those fancy LEDs intended
+	  for reporting mail and wireless status.
+
+	  Note: display switching code is currently considered EXPERIMENTAL,
+	  toying with these values may even lock your machine.
+
+	  All settings are changed via /proc/acpi/asus directory entries. Owner
+	  and group for these entries can be set with asus_uid and asus_gid
+	  parameters.
+
+	  More information and a userspace daemon for handling the extra buttons
+	  at <http://sourceforge.net/projects/acpi4asus/>.
+
+	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
+	  driver is still under development, so if your laptop is unsupported or
+	  something works not quite as expected, please use the mailing list
+	  available on the above page (acpi4asus-user@lists.sourceforge.net).
+
+	  NOTE: This driver is deprecated and will probably be removed soon,
+	  use asus-laptop instead.
+
+config ACPI_TOSHIBA
+	tristate "Toshiba Laptop Extras"
+	depends on ACPI
+	depends on INPUT
+	select INPUT_POLLDEV
+	select NET
+	select RFKILL
+	select BACKLIGHT_CLASS_DEVICE
+	---help---
+	  This driver adds support for access to certain system settings
+	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
+	  their lack of a BIOS setup menu and APM support.
+
+	  On these machines, all system configuration is handled through the
+	  ACPI.  This driver is required for access to controls not covered
+	  by the general ACPI drivers, such as LCD brightness, video output,
+	  etc.
+
+	  This driver differs from the non-ACPI Toshiba laptop driver (located
+	  under "Processor type and features") in several aspects.
+	  Configuration is accessed by reading and writing text files in the
+	  /proc tree instead of by program interface to /dev.  Furthermore, no
+	  power management functions are exposed, as those are handled by the
+	  general ACPI drivers.
+
+	  More information about this driver is available at
+	  <http://memebeam.org/toys/ToshibaAcpiDriver>.
+
+	  If you have a legacy free Toshiba laptop (such as the Libretto L1
+	  series), say Y.

+
+1: The RX get too much "CRC failed" pakets, it make the card work very unstable,
+2: After running a while, the card will get infinity "RX Frame" and "Error"
+interrupt, not know the root reason so far, try to fix it
+3: Using two tx queue txd and txm but not only txm.
+4: Set the hdr correctly.
+5: Try to do recalibrate correvtly
+6: To support G mode in future
+7: Fix the mac address can't be readed and set correctly in BE machine.
+8: Fix include and exclude FCS in promisous mode and manage mode
+9: Using sta_notify to notice sta change
+10: Turn on frame reception at the end of start
+11: Guess the card support HW_MULTICAST_FILTER
+12: The tx process should be implment atomic?
+13: Using mac80211 function to control the TX&RX LED.

+DONE:
+    - functionality similar to logic testbench
+
+TODO:
+	- checkpatch.pl cleanups.
+	- keep state of DMA engines.
+	- keep data structure that keeps state of each transfer.
+	- interrupt handler should iterate over outstanding descriptor tables.
+	- complete userspace cdev to read/write using the DMA engines.
+	- split off the DMA support functions in a module, re-usable by custom

+ *
+ *
+ * Rationale: This driver exercises the chaining DMA read and write engine
+ * in the reference design. It is meant as a complementary reference
+ * driver that can be used for testing early designs as well as a basis to
+ * write your custom driver.
+ *
+ * Status: Test results from Leon Woestenberg  <leon.woestenberg@axon.tv>:
+ *
+ * Sendero Board w/ Cyclone II EP2C35F672C6N, PX1011A PCIe x1 PHY on a
+ * Dell Precision 370 PC, x86, kernel 2.6.20 from Ubuntu 7.04.
+ *
+ * Sendero Board w/ Cyclone II EP2C35F672C6N, PX1011A PCIe x1 PHY on a
+ * Freescale MPC8313E-RDB board, PowerPC, 2.6.24 w/ Freescale patches.
+ *
+ * Driver tests passed with PCIe Compiler 8.1. With PCIe 8.0 the DMA
+ * loopback test had reproducable compare errors. I assume a change
+ * in the compiler or reference design, but could not find evidence nor
+ * documentation on a change or fix in that direction.
+ *
+ * The reference design does not have readable locations and thus a
+ * dummy read, used to flush PCI posted writes, cannot be performed.

+
+    Driver for Asus OLED display present in some Asus laptops.
+
+    The code of this driver is based on 'asusoled' program taken from
+    https://launchpad.net/asusoled/. I just wanted to have a simple
+    kernel driver for controlling this device, but I didn't know how
+    to do that. Now I know ;) Also, that program can not be used
+    with usbhid loaded, which means no USB mouse/keyboard while
+    controlling OLED display :(
+
+    It has been tested on Asus G1 and didn't cause any problems,
+    but I don't guarantee that it won't do anything wrong :)
+
+    It can (and probably does) have errors. It is usable
+    in my case, and I hope others will find it useful too!
+
+*******
+
+Building the module
+
+   To build the module you need kernel 2.6 include files and some C compiler.
+
+   Just run:
+   make
+   make install (as a root)
+
+   It will build (hopefully) the module and install it in
+   /lib/modules/'uname -r'/extra/asus_oled.ko.
+
+   To load it just use:
+   modprobe asus_oled
+
+   You can check if it has detected your OLED display by looking into dmesg output.
+   There should be something like this:
+   asus-oled 2-7:1.0: Attached Asus OLED device
+
+   If it doesn't find your display, you can try removing usbhid module.
+   If you add asus_oled into the list of modules loaded during system boot
+   before usbhid, it will work even when usbhid is present.
+
+   If it still doesn't detect your hardware, check lsusb output.
+   There should be similar line:
+   Bus 002 Device 005: ID 0b05:1726 ASUSTek Computer, Inc.
+
+   If you don't see any lines with '0b05:1726' it means that you have different
+   type of hardware that is not detected (it may or may not work, but the driver
+   knows only '0b05:1726' device).
+
+*******
+
+Configuration
+
+   There is only one option: start_off.
+   You can use it by: 'modprobe asus_oled start_off=1', or by adding this
+   line to /etc/modprobe.conf:
+   options asus_oled start_off=1
+
+   With this option provided, asus_oled driver will switch off the display
+   when it is detected and attached. It is nice feature to just switch off the 'ASUS'
+   logo. If you don't use the display, it is probably the good idea to switch it off,
+   to protect OLEDs from "wearing off".
+
+*******
+
+Usage
+
+   This module can be controlled with two special files:
+   /sys/class/asus_oled/oled_N/enabled
+   /sys/class/asus_oled/oled_N/picture
+
+   (N is the device number, the first, and probably the only, has number 1,
+    so it is /sys/class/asus_oled/oled_1/enabled
+    and /sys/class/asus_oled/oled_1/picture)
+
+   'enabled' files is for reading and writing, 'picture' is writeable only.
+
+   You can write 0 or 1 to 'enabled' file, which will switch
+   on and off the display. Reading from this file will tell you the last
+   status set, either 0 or 1. By default it is 1, so if the device was set to 'off',
+   and the computer was rebooted without power-off, this file will contain wrong
+   value - because the device is off, but hasn't been disabled this time and is
+   assumed to be on...
+
+   To 'picture' file you write pictures to be displayed by the OLED device.
+   The format of the file:
+   <M:WxH>
+   00001110010111000
+   00010101010101010
+   ....
+
+   First line is a configuration parameter. Meaning of fields in <M:WxH>:
+   M - picture mode. It can be either 's' for static pictures,
+       'r' for rolling pictures, and 'f' for flashing pictures.
+   W - width of the picture. May be between 1 and 1792
+   H - height of the picture. May be between 1 and 32
+
+   For example <s:128x32> means static picture, 128 pixels long and 32 pixels high.
+
+   The physical size of the display is 128x32 pixels. Static and flashing pictures
+   can't be larger than that (actually they can, but only part of them will be displayed ;) )
+
+   If the picture is smaller than 128x32 it will be centered. Rolling pictures wider than
+   128 pixels will be centered too, unless their width = n*128. Vertically they will be
+   centered just like static pictures, if their height is smaller than 32.
+
+   Flashing pictures will be centered horizontally if their width < 128, but they were
+   centered vertically in a different way. If their height < 16, they will be centered
+   in the upper half of the display (rows 0-15). This is because only the first half
+   of flashing pictures is used for flashing. When the picture with heigh = 32 is
+   displayed in flashing mode, its upper 16 rows will be flashing in the upper half
+   of the display, and the lower half will be empty. After few seconds upper part will
+   stop flashing (but that part of the picture will remain there), and the lower
+   half of the display will start displayin the lower half of the picture
+   in rolling mode, unless it is empty, or the picture was small enough to fit in
+   upper part. It is not mine idea, this is just the way Asus' display work ;)
+   So if you need just flashing, use at most 128x16 picture. If you need flashing and
+   rolling, use whole size of the display.
+
+   Lines following the first, configuration, line are picture data. Each '1' means
+   that the pixel is lit, and '0' means that it is not. You can also use '#' as ON,
+   and ' ' (space) as OFF. Empty lines and all other characters are ignored.
+
+   It is possible to write everything in one line <M:WxH>01010101010101010...,
+   and W*H characters will be used. If there is not enough characters, nothing will be
+   displayed. However, the 'line mode' is easier to read (and write), and it also
+   lets to omit parts of data. Whenever End-Of-Line character is found, but
+   the line is not W characters long, it is assumed that all missing characters
+   are equal to the last character in the line.
+
+   Following line represents '0', '1' and a lots of '0's, dependng on the width of the picture
+   provided in configuration data:
+   010
+
+   So if you need empty line, it is sufficient to write line with only one '0' in it.
+   The same works with '1' (or ' ' and '#').
+
+   If there are too many data in the file, they will be ignored. If you are not sure
+   how many characters you are missing, you can add few lines with one zero in each of them.
+
+   There are some example pictures in .txt format, that can be used as follows:
+   cat foo.txt > /sys/class/asus_oled/oled_1/picture
+
+   If the display is switched off you also need to run:
+   echo 1 > /sys/class/asus_oled/oled_1/enabled
+   To switch it off, just use:
+   echo 0 > /sys/class/asus_oled/oled_1/enabled
+

+Driver: comedi_bond
+Description: A driver to 'bond' (merge) multiple subdevices from multiple
+	     devices together as one.
+Devices:
+Author: ds
+Updated: Mon, 10 Oct 00:18:25 -0500
+Status: works
+
+This driver allows you to 'bond' (merge) multiple comedi subdevices
+(coming from possibly difference boards and/or drivers) together.  For
+example, if you had a board with 2 different DIO subdevices, and
+another with 1 DIO subdevice, you could 'bond' them with this driver
+so that they look like one big fat DIO subdevice.  This makes writing
+applications slightly easier as you don't have to worry about managing
+different subdevices in the application -- you just worry about
+indexing one linear array of channel id's.
+
+Right now only DIO subdevices are supported as that's the personal itch
+I am scratching with this driver.  If you want to add support for AI and AO
+subdevs, go right on ahead and do so!
+
+Commands aren't supported -- although it would be cool if they were.
+
+Configuration Options:
+  List of comedi-minors to bond.  All subdevices of the same type
+  within each minor will be concatenated together in the order given here.

+ * The previous block comment is used to automatically generate
+ * documentation in Comedi and Comedilib.  The fields:
+ *
+ * Driver: the name of the driver
+ * Description: a short phrase describing the driver.  Don't list boards.
+ * Devices: a full list of the boards that attempt to be supported by
+ *   the driver.  Format is "(manufacturer) board name [comedi name]",
+ *   where comedi_name is the name that is used to configure the board.
+ *   See the comment near board_name: in the comedi_driver structure
+ *   below.  If (manufacturer) or [comedi name] is missing, the previous
+ *   value is used.
+ * Author: you
+ * Updated: date when the _documentation_ was last updated.  Use 'date -R'
+ *   to get a value for this.
+ * Status: a one-word description of the status.  Valid values are:
+ *   works - driver works correctly on most boards supported, and
+ *     passes comedi_test.
+ *   unknown - unknown.  Usually put there by ds.
+ *   experimental - may not work in any particular release.  Author
+ *     probably wants assistance testing it.
+ *   bitrotten - driver has not been update in a long time, probably
+ *     doesn't work, and probably is missing support for significant
+ *     Comedi interface features.
+ *   untested - author probably wrote it "blind", and is believed to
+ *     work, but no confirmation.
+ *
+ * These headers should be followed by a blank line, and any comments
+ * you wish to say about the driver.  The comment area is the place
+ * to put any known bugs, limitations, unsupported features, supported
+ * command triggers, whether or not commands are supported on particular
+ * subdevices, etc.
+ *
+ * Somewhere in the comment should be information about configuration
+ * options that are used with comedi_config.

+
+Notes:
+
+Subdevices 0 is digital I/O, subdevice 1 is digital input, and
+subdevice 2 is digital output.  Unlike other Comedi devices,
+subdevice 0 defaults to output.
+
+Pins 13 and 14 are inverted once by Comedi and once by the
+hardware, thus cancelling the effect.
+
+Pin 1 is a strobe, thus acts like one.  There's no way in software
+to change this, at least on a standard parallel port.
+
+Subdevice 3 pretends to be a digital input subdevice, but it always
+returns 0 when read.  However, if you run a command with
+scan_begin_src=TRIG_EXT, it uses pin 10 as a external triggering
+pin, which can be used to wake up tasks.

+
+This driver is mainly for testing purposes, but can also be used to
+generate sample waveforms on systems that don't have data acquisition
+hardware.
+
+Configuration options:
+  [0] - Amplitude in microvolts for fake waveforms (default 1 volt)
+  [1] - Period in microseconds for fake waveforms (default 0.1 sec)
+
+Generates a sawtooth wave on channel 0, square wave on channel 1, additional
+waveforms could be added to other channels (currently they return flatline
+zero volts).

+Driver: dt9812
+Description: Data Translation DT9812 USB module
+Author: anders.blomdell@control.lth.se (Anders Blomdell)
+Status: in development
+Devices: [Data Translation] DT9812 (dt9812)
+Updated: Sun Nov 20 20:18:34 EST 2005
+
+This driver works, but bulk transfers not implemented. Might be a starting point
+for someone else. I found out too late that USB has too high latencies (>1 ms)
+for my needs.
+*/
+
+/*
+ * Nota Bene:
+ *   1. All writes to command pipe has to be 32 bytes (ISP1181B SHRTP=0 ?)
+ *   2. The DDK source (as of sep 2005) is in error regarding the
+ *      input MUX bits (example code says P4, but firmware schematics
+ *      says P1).

+Driver: icp_multi
+Description: Inova ICP_MULTI
+Author: Anne Smorthit <anne.smorthit@sfwte.ch>
+Devices: [Inova] ICP_MULTI (icp_multi)
+Status: works
+
+The driver works for analog input and output and digital input and output.
+It does not work with interrupts or with the counters.  Currently no support
+for DMA.
+
+It has 16 single-ended or 8 differential Analogue Input channels with 12-bit
+resolution.  Ranges : 5V, 10V, +/-5V, +/-10V, 0..20mA and 4..20mA.  Input
+ranges can be individually programmed for each channel.  Voltage or current
+measurement is selected by jumper.
+
+There are 4 x 12-bit Analogue Outputs.  Ranges : 5V, 10V, +/-5V, +/-10V
+
+16 x Digital Inputs, 24V
+
+8 x Digital Outputs, 24V, 1A
+
+4 x 16-bit counters
+
+Options:
+ [0] - PCI bus number - if bus number and slot number are 0,
+                        then driver search for first unused card
+ [1] - PCI slot number

+Driver: me4000
+Description: Meilhaus ME-4000 series boards
+Devices: [Meilhaus] ME-4650 (me4000), ME-4670i, ME-4680, ME-4680i, ME-4680is
+Author: gg (Guenter Gebhardt <g.gebhardt@meilhaus.com>)
+Updated: Mon, 18 Mar 2002 15:34:01 -0800
+Status: broken (no support for loading firmware)
+
+Supports:
+
+    - Analog Input
+    - Analog Output
+    - Digital I/O
+    - Counter
+
+Configuration Options:
+
+    [0] - PCI bus number (optional)
+    [1] - PCI slot number (optional)
+
+    If bus/slot is not specified, the first available PCI
+    device will be used.
+
+The firmware required by these boards is available in the
+comedi_nonfree_firmware tarball available from
+http://www.comedi.org.  However, the driver's support for
+loading the firmware through comedi_config is currently
+broken.

+Driver: me_daq
+Description: Meilhaus PCI data acquisition cards
+Author: Michael Hillmann <hillmann@syscongroup.de>
+Devices: [Meilhaus] ME-2600i (me_daq), ME-2000i
+Status: experimental
+
+Supports:
+
+    Analog Output
+
+Configuration options:
+
+    [0] - PCI bus number (optional)
+    [1] - PCI slot number (optional)
+
+    If bus/slot is not specified, the first available PCI
+    device will be used.
+
+The 2600 requires a firmware upload, which can be accomplished
+using the -i or --init-data option of comedi_config.
+The firmware can be
+found in the comedi_nonfree_firmware tarball available
+from http://www.comedi.org

+    Created by Dan Christian, NASA Ames Research Center.
+
+    The PCI4520 is a PCI card.  The DM7520 is a PC/104-plus card.
+    Both have:
+    8/16 12 bit ADC with FIFO and channel gain table
+    8 bits high speed digital out (for external MUX) (or 8 in or 8 out)
+    8 bits high speed digital in with FIFO and interrupt on change (or 8 IO)
+    2 12 bit DACs with FIFOs
+    2 bits output
+    2 bits input
+    bus mastering DMA
+    timers: ADC sample, pacer, burst, about, delay, DA1, DA2
+    sample counter
+    3 user timer/counters (8254)
+    external interrupt
+
+    The DM7520 has slightly fewer features (fewer gain steps).
+
+    These boards can support external multiplexors and multi-board
+    synchronization, but this driver doesn't support that.
+
+    Board docs: http://www.rtdusa.com/PC104/DM/analog%20IO/dm7520.htm
+    Data sheet: http://www.rtdusa.com/pdf/dm7520.pdf
+    Example source: http://www.rtdusa.com/examples/dm/dm7520.zip
+    Call them and ask for the register level manual.
+    PCI chip: http://www.plxtech.com/products/toolbox/9080.htm
+
+    Notes:
+    This board is memory mapped.  There is some IO stuff, but it isn't needed.
+
+    I use a pretty loose naming style within the driver (rtd_blah).
+    All externally visible names should be rtd520_blah.
+    I use camelCase for structures (and inside them).
+    I may also use upper CamelCase for function names (old habit).
+
+    This board is somewhat related to the RTD PCI4400 board.
+
+    I borrowed heavily from the ni_mio_common, ni_atmio16d, mite, and
+    das1800, since they have the best documented code.  Driver
+    cb_pcidas64.c uses the same DMA controller.
+
+    As far as I can tell, the About interrupt doesnt work if Sample is
+    also enabled.  It turns out that About really isn't needed, since
+    we always count down samples read.
+
+    There was some timer/counter code, but it didn't follow the right API.

+/*
+  driver status:
+
+  Analog-In supports instruction and command mode.
+
+  With DMA, you can sample at 1.15Mhz with 70% idle on a 400Mhz K6-2
+  (single channel, 64K read buffer).  I get random system lockups when
+  using DMA with ALI-15xx based systems.  I haven't been able to test
+  any other chipsets.  The lockups happen soon after the start of an
+  acquistion, not in the middle of a long run.
+
+  Without DMA, you can do 620Khz sampling with 20% idle on a 400Mhz K6-2
+  (with a 256K read buffer).
+
+  Digital-IO and Analog-Out only support instruction mode.

+Driver: s626
+Description: Sensoray 626 driver
+Devices: [Sensoray] 626 (s626)
+Authors: Gianluca Palli <gpalli@deis.unibo.it>,
+Updated: Fri, 15 Feb 2008 10:28:42 +0000
+Status: experimental
+
+Configuration options:
+  [0] - PCI bus of device (optional)
+  [1] - PCI slot of device (optional)
+  If bus/slot is not specified, the first supported
+  PCI device found will be used.
+
+INSN_CONFIG instructions:
+  analog input:
+   none
+
+  analog output:
+   none
+
+  digital channel:
+   s626 has 3 dio subdevices (2,3 and 4) each with 16 i/o channels
+   supported configuration options:
+   INSN_CONFIG_DIO_QUERY
+   COMEDI_INPUT
+   COMEDI_OUTPUT
+
+  encoder:
+   Every channel must be configured before reading.
+
+   Example code
+
+   insn.insn=INSN_CONFIG;   //configuration instruction
+   insn.n=1;                //number of operation (must be 1)
+   insn.data=&initialvalue; //initial value loaded into encoder

+  Description: Sensoray 626 driver
+  Devices: Sensoray s626
+  Authors: Gianluca Palli <gpalli@deis.unibo.it>,
+  Updated: Thu, 12 Jul 2005
+  Status: experimental
+
+  Configuration Options:
+  analog input:
+   none
+
+  analog output:
+   none
+
+  digital channel:
+   s626 has 3 dio subdevices (2,3 and 4) each with 16 i/o channels
+   supported configuration options:
+   INSN_CONFIG_DIO_QUERY
+   COMEDI_INPUT
+   COMEDI_OUTPUT
+
+  encoder:
+   Every channel must be configured before reading.
+
+   Example code
+
+   insn.insn=INSN_CONFIG;   //configuration instruction
+   insn.n=1;                //number of operation (must be 1)
+   insn.data=&initialvalue; //initial value loaded into encoder
+                            //during configuration
+   insn.subdev=5;           //encoder subdevice
+   insn.chanspec=CR_PACK(encoder_channel,0,AREF_OTHER); //encoder_channel
+                                                        //to configure

+Driver: usbdux
+Description: University of Stirling USB DAQ & INCITE Technology Limited
+Devices: [ITL] USB-DUX (usbdux.o)
+Author: Bernd Porr <BerndPorr@f2s.com>
+Updated: 25 Nov 2007
+Status: Testing
+Configuration options:
+  You have to upload firmware with the -i option. The
+  firmware is usually installed under /usr/share/usb or
+  /usr/local/share/usb or /lib/firmware.
+
+Connection scheme for the counter at the digital port:
+  0=/CLK0, 1=UP/DOWN0, 2=RESET0, 4=/CLK1, 5=UP/DOWN1, 6=RESET1.
+  The sampling rate of the counter is approximately 500Hz.
+
+Please note that under USB2.0 the length of the channel list determines
+the max sampling rate. If you sample only one channel you get 8kHz
+sampling rate. If you sample two channels you get 4kHz and so on.

+ * I must give credit here to Chris Baugher who

+ * who supported me with the USB development.
+ *
+ * Bernd Porr
+ *
+ *
+ * Revision history:
+ * 0.94: D/A output should work now with any channel list combinations
+ * 0.95: .owner commented out for kernel vers below 2.4.19
+ *       sanity checks in ai/ao_cmd
+ * 0.96: trying to get it working with 2.6, moved all memory alloc to comedi's
+ *       attach final USB IDs
+ *       moved memory allocation completely to the corresponding comedi
+ *       functions firmware upload is by fxload and no longer by comedi (due to
+ *       enumeration)
+ * 0.97: USB IDs received, adjusted table
+ * 0.98: SMP, locking, memroy alloc: moved all usb memory alloc
+ *       to the usb subsystem and moved all comedi related memory
+ *       alloc to comedi.
+ *       | kernel | registration | usbdux-usb | usbdux-comedi | comedi |
+ * 0.99: USB 2.0: changed protocol to isochronous transfer
+ *                IRQ transfer is too buggy and too risky in 2.0
+ *                for the high speed ISO transfer is now a working version
+ *                available
+ * 0.99b: Increased the iso transfer buffer for high sp.to 10 buffers. Some VIA
+ *        chipsets miss out IRQs. Deeper buffering is needed.
+ * 1.00: full USB 2.0 support for the A/D converter. Now: max 8kHz sampling
+ *       rate.
+ *       Firmware vers 1.00 is needed for this.
+ *       Two 16 bit up/down/reset counter with a sampling rate of 1kHz
+ *       And loads of cleaning up, in particular streamlining the
+ *       bulk transfers.
+ * 1.1:  moved EP4 transfers to EP1 to make space for a PWM output on EP4
+ * 1.2:  added PWM suport via EP4
+ * 2.0:  PWM seems to be stable and is not interfering with the other functions
+ * 2.1:  changed PWM API

+ * I must give credit here to Chris Baugher who

+ *
+ * Bernd Porr
+ *
+ *
+ * Revision history:
+ * 0.9: Dropping the first data packet which seems to be from the last transfer.
+ *      Buffer overflows in the FX2 are handed over to comedi.
+ * 0.92: Dropping now 4 packets. The quad buffer has to be emptied.
+ *       Added insn command basically for testing. Sample rate is 1MHz/16ch=62.5kHz
+ * 0.99: Ian Abbott pointed out a bug which has been corrected. Thanks!
+ * 0.99a: added external trigger.

+// Buffer handling:
+// All buffers are created statically (i.e. at compile time resp. at
+// initialisation via kmalloc() ) and not dynamically on request (i.e. via
+// EdrvAllocTxMsgBuffer().
+// EdrvAllocTxMsgBuffer() searches for an unused buffer which is large enough.
+// EdrvInit() may allocate some buffers with sizes less than maximum frame
+// size (i.e. 1514 bytes), e.g. for SoC, SoA, StatusResponse, IdentResponse,
+// NMT requests / commands. The less the size of the buffer the less the
+// number of the buffer.

+               To save code space the functions AmiSetByte and AmiGetByte
+               are replaced by macros. For targets which assign BYTE by
+               an 16Bit type, the definition of macros must changed to
+               functions.
+
+   23.02.2005  r.d.:
+               Functions included for extended data types such as UNSIGNED24,
+               UNSIGNED40, ...
+
+   13.06.2006  d.k.:
+               Extended the interface for EPL with the different functions
+               for little endian and big endian

+This directory contains the USB Tranzport and Alphatrack Kernel drivers for Linux.
+
+At present the tranzport does reads/writes of 8 byte cmds to /dev/tranzport0 to control
+the lights and screen and wheel
+
+At present the alphatrack accepts reads/writes of 12 byte cmds to /dev/tranzport0 to control
+the lights and screen and fader.
+
+Both drivers also have some sysfs hooks that are non-functional at the moment.
+
+The API is currently closely tied to the ardour revision and WILL change.
+
+A sysfs interface is PERFECT for simple userspace apps to do fun things with the
+lights and screen. It's fairly lousy for handling input events and very lousy
+for watching the state of the shuttle wheel.
+
+A linux input events interface is great for the input events and shuttle wheel. It's
+theoretically OK on LEDs. A Fader can be mapped to an absolute mouse device.
+But there is no LCD support at all.
+
+In the end this is going to be driven by a midi layer, which handles all those
+cases via a defined API, but - among other things - is slow, doesn't do
+flow control, and is a LOT of extra work. Frankly, I'd like to keep the
+core driver simple because the only realtime work really required is
+the bottom half interrupt handler and the output overlapping.
+
+Exposing some sort of clean aio api to userspace would be perfect. What that
+API looks like? Gah. beats me.

+
+  0. OVERVIEW AND LICENSING/DISCLAIMER
+
+
+This driver kit contains Linux drivers for the WIS GO7007SB multi-format
+video encoder.  Only kernel version 2.6.x is supported.  The video stream
+is available through the Video4Linux2 API and the audio stream is available
+through the ALSA API (or the OSS emulation layer of the ALSA system).
+
+The files in kernel/ and hotplug/ are licensed under the GNU General Public
+License Version 2 from the Free Software Foundation.  A copy of the license
+is included in the file COPYING.
+
+The example applications in apps/ and C header files in include/ are
+licensed under a permissive license included in the source files which
+allows copying, modification and redistribution for any purpose without
+attribution.
+
+The firmware files included in the firmware/ directory may be freely
+redistributed only in conjunction with this document; but modification,
+tampering and reverse engineering are prohibited.
+
+MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH
+RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR
+LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION
+WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR
+PURPOSE AND NON-INFRINGEMENT.
+
+
+  1. SYSTEM REQUIREMENTS
+
+
+This driver requires Linux kernel 2.6.  Kernel 2.4 is not supported.  Using
+kernel 2.6.10 or later is recommended, as earlier kernels are known to have
+unstable USB 2.0 support.
+
+A fully built kernel source tree must be available.  Typically this will be
+linked from "/lib/modules/<KERNEL VERSION>/build" for convenience.  If this
+link does not exist, an extra parameter will need to be passed to the
+`make` command.
+
+All vendor-built kernels should already be configured properly.  However,
+for custom-built kernels, the following options need to be enabled in the
+kernel as built-in or modules:
+
+        CONFIG_HOTPLUG           - Support for hot-pluggable devices
+        CONFIG_MODULES           - Enable loadable module support
+        CONFIG_KMOD              - Automatic kernel module loading
+        CONFIG_FW_LOADER         - Hotplug firmware loading support
+        CONFIG_I2C               - I2C support
+        CONFIG_VIDEO_DEV         - Video For Linux
+        CONFIG_SOUND             - Sound card support
+        CONFIG_SND               - Advanced Linux Sound Architecture
+        CONFIG_USB               - Support for Host-side USB
+        CONFIG_USB_DEVICEFS      - USB device filesystem
+        CONFIG_USB_EHCI_HCD      - EHCI HCD (USB 2.0) support
+
+Additionally, to use the example application, the following options need to
+be enabled in the ALSA section:
+
+        CONFIG_SND_MIXER_OSS     - OSS Mixer API
+        CONFIG_SND_PCM_OSS       - OSS PCM (digital audio) API
+
+The hotplug scripts, along with the fxload utility, must also be installed.
+These scripts can be obtained from <http://linux-hotplug.sourceforge.net/>.
+Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using
+fxload and for loading firmware into the driver using the firmware agent.
+
+
+  2. COMPILING AND INSTALLING THE DRIVER
+
+
+Most users should be able to compile the driver by simply running:
+
+        $ make
+
+in the top-level directory of the driver kit.  First the kernel modules
+will be built, followed by the example applications.
+
+If the build system is unable to locate the kernel source tree for the
+currently-running kernel, or if the module should be built for a kernel
+other than the currently-running kernel, an additional parameter will need
+to be passed to make to specify the appropriate kernel source directory:
+
+        $ make KERNELSRC=/usr/src/linux-2.6.10-custom3
+
+Once the compile completes, the driver and firmware files should be
+installed by running:
+
+        $ make install
+
+The kernel modules will be placed in "/lib/modules/<KERNEL VERSION>/extra"
+and the firmware files will be placed in the appropriate hotplug firmware
+directory, usually /lib/firmware.  In addition, USB maps and scripts will
+be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB
+control chip when the device is connected.
+
+
+  3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only)
+
+
+The PAL model of the Plextor ConvertX TV402U may require additional
+configuration to correctly select the appropriate TV frequency band and
+audio subchannel.
+
+Users with a device other than the Plextor ConvertX TV402U-EU should skip
+this section.
+
+The wide variety of PAL TV systems used in Europe requires that additional
+information about the local TV standards be passed to the driver in order
+to properly tune TV channels.  The two necessary parameters are (a) the PAL
+TV band, and (b) the audio subchannel format in use.
+
+In many cases, the appropriate TV band selection is passed to the driver
+from applications.  However, in some cases, the application only specifies
+that the driver should use PAL but not the specific information about the
+appropriate TV band.  To work around this issue, the correct TV band may be
+specified in the "force_band" parameter to the wis-sony-tuner module:
+
+     TV band           force_band
+     -------           ----------
+     PAL B/G                B
+     PAL I                  I
+     PAL D/K                D
+     SECAM L                L
+
+If the "force_band" parameter is specified, the driver will ignore any TV
+band specified by applications and will always use the band provided in the
+module parameter.
+
+The other parameter that can be specified is the audio subchannel format.
+There are several stereo audio carrier systems in use, including NICAM and
+three varieties of A2.  To receive audio broadcast on one of these stereo
+carriers, the "force_mpx_mode" parameter must be specified to the
+wis-sony-tuner module.
+
+     TV band           Audio subcarrier       force_mpx_mode
+     -------           ----------------       --------------
+     PAL B/G            Mono (default)               1
+     PAL B/G                  A2                     2
+     PAL B/G                 NICAM                   3
+     PAL I              Mono (default)               4
+     PAL I                   NICAM                   5
+     PAL D/K            Mono (default)               6
+     PAL D/K                 A2 (1)                  7
+     PAL D/K                 A2 (2)                  8
+     PAL D/K                 A2 (3)                  9
+     PAL D/K                 NICAM                  10
+     SECAM L            Mono (default)              11
+     SECAM L                 NICAM                  12
+
+If the "force_mpx_mode" parameter is not specified, the correct mono-only
+mode will be chosen based on the TV band.  However, the tuner will not
+receive stereo audio or bilingual broadcasts correctly.
+
+To pass the "force_band" or "force_mpx_mode" parameters to the
+wis-sony-tuner module, the following line must be added to the modprobe
+configuration file, which varies from one Linux distribution to another.
+
+     options wis-sony-tuner force_band=B force_mpx_mode=2
+
+The above example would force the tuner to the PAL B/G TV band and receive
+stereo audio broadcasts on the A2 carrier.
+
+To verify that the configuration has been placed in the correct location,
+execute:
+
+        $ modprobe -c | grep wis-sony-tuner
+
+If the configuration line appears, then modprobe will pass the parameters
+correctly the next time the wis-sony-tuner module is loaded into the
+kernel.
+
+
+  4. TESTING THE DRIVER
+
+
+Because few Linux applications are able to correctly capture from
+Video4Linux2 devices with only compressed formats supported, the new driver
+should be tested with the "gorecord" application in the apps/ directory.
+
+First connect a video source to the device, such as a DVD player or VCR.
+This will be captured to a file for testing the driver.  If an input source
+is unavailable, a test file can still be captured, but the video will be
+black and the audio will be silent.
+
+This application will auto-detect the V4L2 and ALSA/OSS device names of the
+hardware and will record video and audio to an AVI file for a specified
+number of seconds.  For example:
+
+        $ apps/gorecord -duration 60 capture.avi
+
+If this application does not successfully record an AVI file, the error
+messages produced by gorecord and recorded in the system log (usually in
+/var/log/messages) should provide information to help resolve the problem.
+
+Supplying no parameters to gorecord will cause it to probe the available
+devices and exit.  Use the -help flag for usage information.
+
+
+  5. USING THE DRIVER
+
+
+The V4L2 device implemented by the driver provides a standard compressed
+format API, within the following criteria:
+
+  * Applications that only support the original Video4Linux1 API will not
+    be able to communicate with this driver at all.
+
+  * No raw video modes are supported, so applications like xawtv that
+    expect only uncompressed video will not function.
+
+  * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4.
+
+  * MPEG video formats are delivered as Video Elementary Streams only.
+    Program Stream (PS), Transport Stream (TS) and Packetized Elementary
+    Stream (PES) formats are not supported.
+
+  * Video parameters such as format and input port may not be changed while
+    the encoder is active.
+
+  * The audio capture device only functions when the video encoder is
+    actively capturing video.  Attempts to read from the audio device when
+    the encoder is inactive will result in an I/O error.
+
+  * The native format of the audio device is 48Khz 2-channel 16-bit
+    little-endian PCM, delivered through the ALSA system.  No audio
+    compression is implemented in the hardware.  ALSA may convert to other
+    uncompressed formats on the fly.
+
+The include/ directory contains a C header file describing non-standard
+features of the GO7007SB encoder, which are described below:
+
+
+  GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS
+
+    These ioctls are used to negotiate general compression parameters.
+
+    To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl
+    with a pointer to a struct go7007_comp_params.  If the driver is not
+    set to MPEG format, the EINVAL error code will be returned.
+
+    To change the current parameters, initialize all fields of a struct
+    go7007_comp_params and call the GO7007_IOC_S_COMP_PARAMS ioctl with a
+    pointer to this structure.  The driver will return the current
+    parameters with any necessary changes to conform to the limitations of
+    the hardware or current compression mode.  Any or all fields can be set
+    to zero to request a reasonable default value.  If the driver is not
+    set to MPEG format, the EINVAL error code will be returned.  When I/O
+    is in progress, the EBUSY error code will be returned.
+
+    Fields in struct go7007_comp_params:
+
+        __u32                        The maximum number of frames in each
+          gop_size                   Group Of Pictures; i.e. the maximum
+                                     number of frames minus one between
+                                     each key frame.
+
+        __u32                        The maximum number of sequential
+          max_b_frames               bidirectionally-predicted frames.
+                                     (B-frames are not yet supported.)
+
+        enum go7007_aspect_ratio     The aspect ratio to be encoded in the
+          aspect_ratio               meta-data of the compressed format.
+
+                                     Choices are:

+                                        GO7007_ASPECT_RATIO_16_9_PAL

+          flags
+
+    Flags in struct go7007_comp_params:
+
+        GO7007_COMP_CLOSED_GOP       Only produce self-contained GOPs, used
+                                     to produce streams appropriate for
+                                     random seeking.
+
+        GO7007_COMP_OMIT_SEQ_HEADER  Omit the stream sequence header.
+
+
+  GO7007IOC_S_MPEG_PARAMS, GO7007IOC_G_MPEG_PARAMS
+
+    These ioctls are used to negotiate MPEG-specific stream parameters when
+    the pixelformat has been set to V4L2_PIX_FMT_MPEG.
+
+    To query the current parameters, call the GO7007IOC_G_MPEG_PARAMS ioctl
+    with a pointer to a struct go7007_mpeg_params.  If the driver is not
+    set to MPEG format, the EINVAL error code will be returned.
+
+    To change the current parameters, initialize all fields of a struct
+    go7007_mpeg_params and call the GO7007_IOC_S_MPEG_PARAMS ioctl with a
+    pointer to this structure.  The driver will return the current
+    parameters with any necessary changes to conform to the limitations of
+    the hardware or selected MPEG mode.  Any or all fields can be set to
+    zero to request a reasonable default value.  If the driver is not set
+    to MPEG format, the EINVAL error code will be returned.  When I/O is in
+    progress, the EBUSY error code will be returned.
+
+    Fields in struct go7007_mpeg_params:
+
+        enum go7007_mpeg_video_standard
+          mpeg_video_standard        The MPEG video standard in which to
+                                     compress the video.
+
+                                     Choices are:

+                                     features used in the video stream.
+                                     Not valid for MPEG1.

+
+    Flags in struct go7007_mpeg_params:

+                                     with DVD MPEG2 stream requirements.
+                                     This overrides most compression and
+                                     bitrate settings!
+
+        GO7007_MPEG_OMIT_GOP_HEADER  Omit the GOP header.
+
+        GO7007_MPEG_REPEAT_SEQHEADER Repeat the MPEG sequence header at
+                                     the start of each GOP.
+
+
+  GO7007IOC_S_BITRATE, GO7007IOC_G_BITRATE
+
+    These ioctls are used to set and query the target bitrate value for the
+    compressed video stream.  The bitrate may be selected by storing the
+    target bits per second in an int and calling GO7007IOC_S_BITRATE with a
+    pointer to the int.  The bitrate may be queried by calling
+    GO7007IOC_G_BITRATE with a pointer to an int where the current bitrate
+    will be stored.
+
+    Note that this is the primary means of controlling the video quality
+    for all compression modes, including V4L2_PIX_FMT_MJPEG.  The
+    VIDIOC_S_JPEGCOMP ioctl is not supported.
+
+
+----------------------------------------------------------------------------
+                   Installing the WIS PCI Voyager Driver
+---------------------------------------------------------------------------
+
+The WIS PCI Voyager driver requires several patches to the Linux 2.6.11.x
+kernel source tree before compiling the driver.  These patches update the
+in-kernel SAA7134 driver to the newest development version and patch bugs
+in the TDA8290/TDA8275 tuner driver.
+
+The following patches must be downloaded from Gerd Knorr's website and
+applied in the order listed:
+
+	http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner
+	http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner2
+	http://dl.bytesex.org/patches/2.6.11-2/v4l2-api-mpeg
+	http://dl.bytesex.org/patches/2.6.11-2/saa7134-update
+
+The following patches are included with this SDK and can be applied in any
+order:
+
+	patches/2.6.11/saa7134-voyager.diff
+	patches/2.6.11/tda8275-newaddr.diff
+	patches/2.6.11/tda8290-ntsc.diff
+
+Check to make sure the CONFIG_VIDEO_SAA7134 option is enabled in the kernel
+configuration, and build and install the kernel.
+
+After rebooting into the new kernel, the GO7007 driver can be compiled and
+installed:
+
+	$ make SAA7134_BUILD=y
+	$ make install
+	$ modprobe saa7134-go7007
+
+There will be two V4L video devices associated with the PCI Voyager.  The
+first device (most likely /dev/video0) provides access to the raw video
+capture mode of the SAA7133 device and is used to configure the source
+video parameters and tune the TV tuner.  This device can be used with xawtv
+or other V4L(2) video software as a standard uncompressed device.
+
+The second device (most likely /dev/video1) provides access to the
+compression functions of the GO7007.  It can be tested using the gorecord
+application in the apps/ directory of this SDK:
+
+	$ apps/gorecord -vdevice /dev/video1 -noaudio test.avi
+
+Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL),
+and the video standard must be specified to both the raw and the compressed
+video devices (xawtv and gorecord, for example).
+
+
+--------------------------------------------------------------------------
+RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER
+---------------------------------------------------------------------------
+
+Last updated: 5 November 2005
+
+ - Release 0.9.7 includes new support for using udev to run fxload.  The
+   install script should automatically detect whether the old hotplug
+   scripts or the new udev rules should be used.  To force the use of
+   hotplug, run "make install USE_UDEV=n".  To force the use of udev, run
+   "make install USE_UDEV=y".
+
+ - Motion detection is supported but undocumented.  Try the `modet` app
+   for a demonstration of how to use the facility.
+
+ - Using USB2.0 devices such as the TV402U with USB1.1 HCDs or hubs can
+   cause buffer overruns and frame drops, even at low framerates, due to
+   inconsistency in the bitrate control mechanism.
+
+ - On devices with an SAA7115, including the Plextor ConvertX, video height
+   values of 96, 128, 160, 192, 256, 320, and 384 do not work in NTSC mode.
+   All valid heights up to 512 work correctly in PAL mode.
+
+ - The WIS Star Trek and PCI Voyager boards have no support yet for audio
+   or the TV tuner.

+	tristate "Atheros OTUS 802.11n USB wireless support"
+	depends on USB && WLAN_80211 && MAC80211
+	default N
+	---help---
+	  Enable support for Atheros 802.11n USB hardware:
+	    * UB81 - 2x2 2.4 GHz
+	    * UB82 - 2x2 2.4 GHz and 5 GHz
+	    * UB83 - 1x2 2.4 GHz
+
+	  This includes the following devices currently on the market:
+	  Dlink DWA-160A1, Netgear WNDA3100 and WN111v2, TP-Link
+	  TL-WN821N, and AVM FRITZ!WLAN N USB Stick.
+
+	  This driver requires its own supplicant driver for
+	  wpa_supplicant 0.4.8. For your convenience you can find the
+	  tarball here:
+
+	  http://www.kernel.org/pub/linux/kernel/people/mcgrof/otus/wpa_supplicant-0.4.8_otus.tar.bz2
+
+	  Before compiling wpa_supplicant, ensure your .config has at
+	  least the following:
+		CONFIG_WIRELESS_EXTENSION=y
+		CONFIG_EAP_WSC=y
+		CONFIG_WSC_IE=y
+		CONFIG_DRIVER_WEXT=y
+		CONFIG_DRIVER_OTUS=y
+
+	  After a successful compile, you can use the Atheros device as
+	  shown in the example:
+	  $ wpa_supplicant -Dotus -i <atheros device from ifconfig> -c /path/to/wpa_supplicant.conf -d

+config PANEL
+	tristate "Parallel port LCD/Keypad Panel support"
+	depends on PARPORT
+	---help---
+	  Say Y here if you have an HD44780 or KS-0074 LCD connected to your
+	  parallel port. This driver also features 4 and 6-key keypads. The LCD
+	  is accessible through the /dev/lcd char device (10, 156), and the
+	  keypad through /dev/keypad (10, 185). Both require misc device to be
+	  enabled. This code can either be compiled as a module, or linked into
+	  the kernel and started at boot. If you don't understand what all this
+	  is about, say N.
+
+config PANEL_PARPORT
+	int "Default parallel port number (0=LPT1)"
+	depends on PANEL
+	range 0 255
+	default "0"
+	---help---
+	  This is the index of the parallel port the panel is connected to. One
+	  driver instance only supports one parallel port, so if your keypad
+	  and LCD are connected to two separate ports, you have to start two
+	  modules with different arguments. Numbering starts with '0' for LPT1,
+	  and so on.
+
+config PANEL_PROFILE
+	int "Default panel profile (0-5, 0=custom)"
+	depends on PANEL
+	range 0 5
+	default "5"
+	---help---
+	  To ease configuration, the driver supports different configuration
+	  profiles for past and recent wirings. These profiles can also be
+	  used to define an approximative configuration, completed by a few
+	  other options. Here are the profiles :
+
+	    0 = custom (see further)
+	    1 = 2x16 parallel LCD, old keypad
+	    2 = 2x16 serial LCD (KS-0074), new keypad
+	    3 = 2x16 parallel LCD (Hantronix), no keypad
+	    4 = 2x16 parallel LCD (Nexcom NSA1045) with Nexcom's keypad
+	    5 = 2x40 parallel LCD (old one), with old keypad
+
+	  Custom configurations allow you to define how your display is
+	  wired to the parallel port, and how it works. This is only intended
+	  for experts.
+
+config PANEL_KEYPAD
+	depends on PANEL && PANEL_PROFILE="0"
+	int "Keypad type (0=none, 1=old 6 keys, 2=new 6 keys, 3=Nexcom 4 keys)"
+	range 0 4
+	default 0
+	---help---
+	  This enables and configures a keypad connected to the parallel port.
+	  The keys will be read from character device 10,185. Valid values are :
+
+	    0 : do not enable this driver
+	    1 : old 6 keys keypad
+	    2 : new 6 keys keypad, as used on the server at www.ant-computing.com
+	    3 : Nexcom NSA1045's 4 keys keypad
+
+	  New profiles can be described in the driver source. The driver also
+	  supports simultaneous keys pressed when the keypad supports them.

+	---help---
+	   This enables and configures an LCD connected to the parallel port.
+	   The driver includes an interpreter for escape codes starting with
+	   '\e[L' which are specific to the LCD, and a few ANSI codes. The
+	   driver will be registered as character device 10,156, usually
+	   under the name '/dev/lcd'. There are a total of 6 supported types :
+
+	     0 : do not enable the driver
+	     1 : custom configuration and wiring (see further)

+	     4 : 2x16 parallel LCD (Hantronix wiring)
+	     5 : 2x16 parallel LCD (Nexcom wiring)
+
+	   When type '1' is specified, other options will appear to configure
+	   more precise aspects (wiring, dimensions, protocol, ...). Please note

+	---help---
+	  Most LCDs use a standard controller which supports hardware lines of 40
+	  characters, although sometimes only 16, 20 or 24 of them are really wired
+	  to the terminal. This results in some non-visible but adressable characters,
+	  and is the case for most parallel LCDs. Other LCDs, and some serial ones,
+	  however, use the same line width internally as what is visible. The KS0074
+	  for example, uses 16 characters per line for 16 visible characters per line.
+
+	  This option lets you configure the value used by your LCD in 'custom' profile.
+	  If you don't know, put '40' here.
+
+config PANEL_LCD_HWIDTH
+	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"
+	int "Hardware LCD line width (1-64, 64 by default)"
+	range 1 64
+	default 64
+	---help---
+	  Most LCDs use a single address bit to differentiate line 0 and line 1. Since
+	  some of them need to be able to address 40 chars with the lower bits, they
+	  often use the immediately superior power of 2, which is 64, to address the
+	  next line.
+
+	  If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and
+	  64 here for a 2x40.

+	range 0 1
+	default 0
+	---help---
+	  Some controllers such as the KS0074 use a somewhat strange character set
+	  where many symbols are at unusual places. The driver knows how to map
+	  'standard' ASCII characters to the character sets used by these controllers.
+	  Valid values are :
+
+	     0 : normal (untranslated) character set
+	     1 : KS0074 character set
+
+	  If you don't know, use the normal one (0).

+	depends on PANEL && PANEL_PROFILE="0" && PANEL_LCD="1"
+	int "LCD communication mode (0=parallel 8 bits, 1=serial)"
+	range 0 1
+	default 0
+	---help---
+	  This driver now supports any serial or parallel LCD wired to a parallel
+	  port. But before assigning signals, the driver needs to know if it will
+	  be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires
+	  (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals
+	  (E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits
+	  parallel LCD, and 1 for a serial LCD.

+Some LCDs allow you to define up to 8 characters, mapped to ASCII
+characters 0 to 7. The escape code to define a new character is
+'\e[LG' followed by one digit from 0 to 7, representing the character
+number, and up to 8 couples of hex digits terminated by a semi-colon
+(';'). Each couple of digits represents a line, with 1-bits for each
+illuminated pixel with LSB on the right. Lines are numberred from the
+top of the character to the bottom. On a 5x7 matrix, only the 5 lower
+bits of the 7 first bytes are used for each character. If the string

+ * This code drives an LCD module (/dev/lcd), and a keypad (/dev/keypad)
+ * connected to a parallel printer port.
+ *
+ * The LCD module may either be an HD44780-like 8-bit parallel LCD, or a 1-bit
+ * serial module compatible with Samsung's KS0074. The pins may be connected in
+ * any combination, everything is programmable.
+ *
+ * The keypad consists in a matrix of push buttons connecting input pins to
+ * data output pins or to the ground. The combinations have to be hard-coded
+ * in the driver, though several profiles exist and adding new ones is easy.
+ *
+ * Several profiles are provided for commonly found LCD+keypad modules on the
+ * market, such as those found in Nexcom's appliances.
+ *
+ * FIXME:
+ *      - the initialization/deinitialization process is very dirty and should
+ *        be rewritten. It may even be buggy.
+ *
+ * TODO:
+ *	- document 24 keys keyboard (3 rows of 8 cols, 32 diodes + 2 inputs)
+ *      - make the LCD a part of a virtual screen of Vx*Vy
+ *	- make the inputs list smp-safe
+ *      - change the keyboard to a double mapping : signals -> key_id -> values
+ *        so that applications can change values without knowing signals

+This driver is for the Princeton Instruments USB camera.
+
+It needs lots of work to get it into the main drivers/usb/ subdirectory:
+
+Any patches to do any of the following changes are greatly appreciated:
+
+	- make checkpatch.pl clean
+	- coding style fixups (typedefs, etc.)
+	- get it to build properly
+	- audit ioctls
+	- remove ioctls if possible
+	- assign proper minor number
+	- remove dbg() macro
+	- lots of general cleanups
+	- review locking
+
+Please send patches to:
+	Greg Kroah-Hartman <gregkh@suse.de>
+and CC:
+	Judd Montgomery <judd@jpilot.org>
+	Jeff Frontz <jeff.frontz@gmail.com>
+as they have this device and can test any needed changes.

+	and then passed down.  The function get_free_pages(...) does the actual mapping of the buffer from user space to
+	kernel space.  From there a scatterlist is created from all the pages.  The next function called is to usb_buffer_map_sg
+	which allocated DMA addresses for each page, even coalescing them if possible.  The DMA address is placed in the scatterlist
+	structure.  The function returns the number of DMA addresses.  This may or may not be equal to the number of pages that
+	the user buffer uses.  We then build an URB for each DMA address and then submit them.

+I'm hesitant to add a TODO file here, as the wireless developers would
+really have people help them out on the "clean" rt2860 driver that can
+be found at the rt2860.sf.net site.
+
+But, if you wish to clean up this driver instead, here's a short list of
+things that need to be done to get it into a more mergable shape:
+
+TODO:
+	- checkpatch.pl clean
+	- sparse clean
+	- port to in-kernel 80211 stack
+	- remove reading from /etc/ config files
+	- review by the wireless developer community
+
+Please send any patches or complaints about this driver to Greg
+Kroah-Hartman <greg@kroah.com> and don't bother the upstream wireless
+kernel developers about it, they want nothing to do with it.

+	Tx Path design algorithm:
+		Basically, we divide the packets into four types, Broadcast/Multicast, 11N Rate(AMPDU, AMSDU, Normal), B/G Rate(ARALINK, Normal),
+		Specific Packet Type. Following show the classification rule and policy for each kinds of packets.
+				Classification Rule=>
+					Multicast: (*addr1 & 0x01) == 0x01
+					Specific : bDHCPFrame, bARPFrame, bEAPOLFrame, etc.
+					11N Rate : If peer support HT
+								(1).AMPDU  -- If TXBA is negotiated.
+								(2).AMSDU  -- If AMSDU is capable for both peer and ourself.
+											*). AMSDU can embedded in a AMPDU, but now we didn't support it.
+								(3).Normal -- Other packets which send as 11n rate.
+
+					B/G Rate : If peer is b/g only.
+								(1).ARALINK-- If both of peer/us supprot Ralink proprietary Aggregation and the TxRate is large than RATE_6
+								(2).Normal -- Other packets which send as b/g rate.
+					Fragment:
+								The packet must be unicast, NOT A-RALINK, NOT A-MSDU, NOT 11n, then can consider about fragment.
+
+				Classified Packet Handle Rule=>
+					Multicast:
+								No ACK, 		//pTxBlk->bAckRequired = FALSE;
+								No WMM, 		//pTxBlk->bWMM = FALSE;
+								No piggyback,   //pTxBlk->bPiggyBack = FALSE;
+								Force LowRate,  //pTxBlk->bForceLowRate = TRUE;
+					Specific :	Basically, for specific packet, we should handle it specifically, but now all specific packets are use
+									the same policy to handle it.
+								Force LowRate,  //pTxBlk->bForceLowRate = TRUE;
+
+					11N Rate :
+								No piggyback,	//pTxBlk->bPiggyBack = FALSE;
+
+								(1).AMSDU
+									pTxBlk->bWMM = TRUE;
+								(2).AMPDU
+									pTxBlk->bWMM = TRUE;
+								(3).Normal
+
+					B/G Rate :

+		Basically, we divide the packets into four types, Broadcast/Multicast, 11N Rate(AMPDU, AMSDU, Normal), B/G Rate(ARALINK, Normal),
+		Specific Packet Type. Following show the classification rule and policy for each kinds of packets.
+				Classification Rule=>
+					Multicast: (*addr1 & 0x01) == 0x01
+					Specific : bDHCPFrame, bARPFrame, bEAPOLFrame, etc.
+					11N Rate : If peer support HT
+								(1).AMPDU  -- If TXBA is negotiated.
+								(2).AMSDU  -- If AMSDU is capable for both peer and ourself.
+											*). AMSDU can embedded in a AMPDU, but now we didn't support it.
+								(3).Normal -- Other packets which send as 11n rate.
+
+					B/G Rate : If peer is b/g only.
+								(1).ARALINK-- If both of peer/us supprot Ralink proprietary Aggregation and the TxRate is large than RATE_6
+								(2).Normal -- Other packets which send as b/g rate.
+					Fragment:
+								The packet must be unicast, NOT A-RALINK, NOT A-MSDU, NOT 11n, then can consider about fragment.
+
+				Classified Packet Handle Rule=>
+					Multicast:
+								No ACK, 		//pTxBlk->bAckRequired = FALSE;
+								No WMM, 		//pTxBlk->bWMM = FALSE;
+								No piggyback,   //pTxBlk->bPiggyBack = FALSE;
+								Force LowRate,  //pTxBlk->bForceLowRate = TRUE;
+					Specific :	Basically, for specific packet, we should handle it specifically, but now all specific packets are use
+									the same policy to handle it.
+								Force LowRate,  //pTxBlk->bForceLowRate = TRUE;
+
+					11N Rate :
+								No piggyback,	//pTxBlk->bPiggyBack = FALSE;
+
+								(1).AMSDU
+									pTxBlk->bWMM = TRUE;
+								(2).AMPDU
+									pTxBlk->bWMM = TRUE;
+								(3).Normal

+					B/G Rate :

+In the event that fragmentation is required, the incoming payload is split into
+N parts of size ieee->fts.  The first fragment contains the SNAP header and the
+remaining packets are just data.
+
+If encryption is enabled, each fragment payload size is reduced by enough space
+to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
+So if you have 1500 bytes of payload with ieee->fts set to 500 without
+encryption it will take 3 frames.  With WEP it will take 4 frames as the
+payload of each frame is reduced to 492 bytes.

-*
-* --------------------------------------------------------------------
-*
-* This file implements functions that correspond to the prism2/hfa384x
-* 802.11 MAC hardware and firmware host interface.
-*
-* The functions can be considered to represent several levels of
-* abstraction.  The lowest level functions are simply C-callable wrappers
-* around the register accesses.  The next higher level represents C-callable
-* prism2 API functions that match the Intersil documentation as closely
-* as is reasonable.  The next higher layer implements common sequences
-* of invokations of the API layer (e.g. write to bap, followed by cmd).
-*
-* Common sequences:
-* hfa384x_drvr_xxx	Highest level abstractions provided by the
-*			hfa384x code.  They are driver defined wrappers
-*			for common sequences.  These functions generally
-*			use the services of the lower levels.
-*
-* hfa384x_drvr_xxxconfig  An example of the drvr level abstraction. These
-*			functions are wrappers for the RID get/set
-*			sequence. They 	call copy_[to|from]_bap() and
-*			cmd_access().	These functions operate on the
-*			RIDs and buffers without validation.  The caller
-*			is responsible for that.
-*
-* API wrapper functions:
-* hfa384x_cmd_xxx	functions that provide access to the f/w commands.
-*			The function arguments correspond to each command
-*			argument, even command arguments that get packed
-*			into single registers.  These functions _just_
-*			issue the command by setting the cmd/parm regs
-*			& reading the status/resp regs.  Additional
-*			activities required to fully use a command
-*			(read/write from/to bap, get/set int status etc.)
-*			are implemented separately.  Think of these as
-*			C-callable prism2 commands.
-*
-* Lowest Layer Functions:
-* hfa384x_docmd_xxx	These functions implement the sequence required
-*			to issue any prism2 command.  Primarily used by the
-*			hfa384x_cmd_xxx functions.
-*
-* hfa384x_bap_xxx	BAP read/write access functions.
-*			Note: we usually use BAP0 for non-interrupt context
-*			 and BAP1 for interrupt context.
-*
-* hfa384x_dl_xxx	download related functions.
-*
-* Driver State Issues:
-* Note that there are two pairs of functions that manage the
-* 'initialized' and 'running' states of the hw/MAC combo.  The four
-* functions are create(), destroy(), start(), and stop().  create()
-* sets up the data structures required to support the hfa384x_*
-* functions and destroy() cleans them up.  The start() function gets
-* the actual hardware running and enables the interrupts.  The stop()
-* function shuts the hardware down.  The sequence should be:
-* create()
-*  .
-*  .  Self contained test routines can run here, particularly
-*  .  corereset() and test_hostif().
-*  .
-* start()
-*  .
-*  .  Do interesting things w/ the hardware
-*  .
-* stop()
-* destroy()
-*
-* Note that destroy() can be called without calling stop() first.

-

-
-		 We have to serialize ALL BAP accesses, and furthermore, add a 5us
-		 delay after access if we're using a PCI platform.
-
-		 Unfortunately, this means we have to lock out interrupts througout
-		 the entire BAP copy.

+ * @iface: USB interface belonging to the device to reset
+ *
+ * This function can be used to reset a USB device from an atomic
+ * context, where usb_reset_device() won't work (as it blocks).
+ *
+ * Doing a reset via this method is functionally equivalent to calling
+ * usb_reset_device(), except for the fact that it is delayed to a
+ * workqueue. This means that any drivers bound to other interfaces
+ * might be unbound, as well as users from usbfs in user space.
+ *
+ * Corner cases:
+ *
+ * - Scheduling two resets at the same time from two different drivers
+ *   attached to two different interfaces of the same device is
+ *   possible; depending on how the driver attached to each interface
+ *   handles ->pre_reset(), the second reset might happen or not.
+ *
+ * - If a driver is unbound and it had a pending reset, the reset will
+ *   be cancelled.
+ *
+ * - This function can be called during .probe() or .disconnect()
+ *   times. On return from .disconnect(), any pending resets will be
+ *   cancelled.
+ *
+ * There is no no need to lock/unlock the @reset_ws as schedule_work()
+ * does its own.
+ *
+ * NOTE: We don't do any reference count tracking because it is not
+ *     needed. The lifecycle of the work_struct is tied to the
+ *     usb_interface. Before destroying the interface we cancel the
+ *     work_struct, so the fact that work_struct is queued and or
+ *     running means the interface (and thus, the device) exist and
+ *     are referenced.

+ * Description: MIPS USB IP core family device controller
+ *              Currently it only supports IP part number CI13412
+ *
+ * This driver is composed of several blocks:
+ * - HW:     hardware interface
+ * - DBG:    debug facilities (optional)
+ * - UTIL:   utilities
+ * - ISR:    interrupts handling
+ * - ENDPT:  endpoint operations (Gadget API)
+ * - GADGET: gadget operations (Gadget API)
+ * - BUS:    bus glue code, bus abstraction layer
+ * - PCI:    PCI core interface and PCI resources (interrupts, memory...)
+ *
+ * Compile Options
+ * - CONFIG_USB_GADGET_DEBUG_FILES: enable debug facilities
+ * - STALL_IN:  non-empty bulk-in pipes cannot be halted
+ *              if defined mass storage compliance succeeds but with warnings
+ *              => case 4: Hi >  Dn
+ *              => case 5: Hi >  Di
+ *              => case 8: Hi <> Do
+ *              if undefined usbtest 13 fails
+ * - TRACE:     enable function tracing (depends on DEBUG)
+ *
+ * Main Features
+ * - Chapter 9 & Mass Storage Compliance with Gadget File Storage
+ * - Chapter 9 Compliance with Gadget Zero (STALL_IN undefined)
+ * - Normal & LPM support
+ *
+ * USBTEST Report
+ * - OK: 0-12, 13 (STALL_IN defined) & 14
+ * - Not Supported: 15 & 16 (ISO)
+ *
+ * TODO List
+ * - OTG
+ * - Isochronous & Interrupt Traffic
+ * - Handle requests which spawns into several TDs
+ * - GET_STATUS(device) - always reports 0
+ * - Gadget API (majority of optional features)
+ * - Suspend & Remote Wakeup

+ * Back reference rules.  Back refs have three main goals:
+ *
+ * 1) differentiate between all holders of references to an extent so that
+ *    when a reference is dropped we can make sure it was a valid reference
+ *    before freeing the extent.
+ *
+ * 2) Provide enough information to quickly find the holders of an extent
+ *    if we notice a given block is corrupted or bad.
+ *
+ * 3) Make it easy to migrate blocks for FS shrinking or storage pool
+ *    maintenance.  This is actually the same as #2, but with a slightly
+ *    different use case.
+ *
+ * File extents can be referenced by:
+ *
+ * - multiple snapshots, subvolumes, or different generations in one subvol
+ * - different files inside a single subvolume
+ * - different offsets inside a file (bookend extents in file.c)
+ *
+ * The extent ref structure has fields for:
+ *
+ * - Objectid of the subvolume root
+ * - Generation number of the tree holding the reference
+ * - objectid of the file holding the reference
+ * - number of references holding by parent node (alway 1 for tree blocks)
+ *
+ * Btree leaf may hold multiple references to a file extent. In most cases,
+ * these references are from same file and the corresponding offsets inside
+ * the file are close together.
+ *
+ * When a file extent is allocated the fields are filled in:
+ *     (root_key.objectid, trans->transid, inode objectid, 1)
+ *
+ * When a leaf is cow'd new references are added for every file extent found
+ * in the leaf.  It looks similar to the create case, but trans->transid will
+ * be different when the block is cow'd.
+ *
+ *     (root_key.objectid, trans->transid, inode objectid,
+ *      number of references in the leaf)
+ *
+ * When a file extent is removed either during snapshot deletion or
+ * file truncation, we find the corresponding back reference and check
+ * the following fields:
+ *
+ *     (btrfs_header_owner(leaf), btrfs_header_generation(leaf),
+ *      inode objectid)
+ *
+ * Btree extents can be referenced by:
+ *
+ * - Different subvolumes
+ * - Different generations of the same subvolume
+ *

+ * Core function of space balance.
+ *
+ * The idea is using reloc trees to relocate tree blocks in reference
+ * counted roots. There is one reloc tree for each subvol, and all
+ * reloc trees share same root key objectid. Reloc trees are snapshots
+ * of the latest committed roots of subvols (root->commit_root).
+ *
+ * To relocate a tree block referenced by a subvol, there are two steps.
+ * COW the block through subvol's reloc tree, then update block pointer
+ * in the subvol to point to the new block. Since all reloc trees share
+ * same root key objectid, doing special handing for tree blocks owned
+ * by them is easy. Once a tree block has been COWed in one reloc tree,
+ * we can use the resulting new block directly when the same block is
+ * required to COW again through other reloc trees. By this way, relocated
+ * tree blocks are shared between reloc trees, so they are also shared
+ * between subvols.

+ * For ioctls, there is no generic way to determine how much memory

+ * to dereference the passed pointer, so the parameter requires deep
+ * copying but FUSE has no idea whatsoever about what to copy in or
+ * out.
+ *
+ * This is solved by allowing FUSE server to retry ioctl with
+ * necessary in/out iovecs.  Let's assume the ioctl implementation
+ * needs to read in the following structure.
+ *
+ * struct a {
+ *	char	*buf;
+ *	size_t	buflen;
+ * }
+ *
+ * On the first callout to FUSE server, inarg->in_size and
+ * inarg->out_size will be NULL; then, the server completes the ioctl
+ * with FUSE_IOCTL_RETRY set in out->flags, out->in_iovs set to 1 and
+ * the actual iov array to
+ *
+ * { { .iov_base = inarg.arg,	.iov_len = sizeof(struct a) } }
+ *
+ * which tells FUSE to copy in the requested area and retry the ioctl.
+ * On the second round, the server has access to the structure and
+ * from that it can tell what to look for next, so on the invocation,
+ * it sets FUSE_IOCTL_RETRY, out->in_iovs to 2 and iov array to
+ *
+ * { { .iov_base = inarg.arg,	.iov_len = sizeof(struct a)	},
+ *   { .iov_base = a.buf,	.iov_len = a.buflen		} }
+ *
+ * FUSE will copy both struct a and the pointed buffer from the
+ * process doing the ioctl and retry ioctl with both struct a and the
+ * buffer.
+ *
+ * This time, FUSE server has everything it needs and completes ioctl
+ * without FUSE_IOCTL_RETRY which finishes the ioctl call.
+ *
+ * Copying data out works the same way.
+ *
+ * Note that if FUSE_IOCTL_UNRESTRICTED is clear, the kernel
+ * automatically initializes in and out iovs by decoding @cmd with
+ * _IOC_* macros and the server is not allowed to request RETRY.  This
+ * limits ioctl data transfers to well-formed ioctls and is the forced
+ * behavior for all FUSE servers.

- * ___constant_swabXX
- *    C versions that gcc can fold into a compile-time constant when
- *    the argument is a compile-time constant.
- *
- * __arch__swabXX[sp]?
- *    Architecture optimized versions of all the swab functions
- *    (including the s and p versions).  These can be defined in
- *    asm-arch/byteorder.h.  Any which are not, are defined here.
- *    __arch__swabXXs() is defined in terms of __arch__swabXXp(), which

- *    in terms of ___swabXX(x).
- *    These must be macros.  They may be unsafe for arguments with
- *    side-effects.
- *
- * __fswabXX
- *    Inline function versions of the __arch__ macros.  These _are_ safe
- *    if the arguments have side-effects.  Note there are no s and p
- *    versions of these.
- *
- * __swabXX[sb]
- *    There are the ones you should actually use.  The __swabXX versions
- *    will be a constant given a constant argument and use the arch
- *    specific code (if any) for non-constant arguments.  The s and p
- *    versions always use the arch specific code (constant folding
- *    doesn't apply).  They are safe to use with arguments with
- *    side-effects.

- * swabXX[sb]
- *    Nicknames for __swabXX[sb] to use in the kernel.

+ * enum wimax_st - The different states of a WiMAX device
+ * @__WIMAX_ST_NULL: The device structure has been allocated and zeroed,
+ *     but still wimax_dev_add() hasn't been called. There is no state.
+ *
+ * @WIMAX_ST_DOWN: The device has been registered with the WiMAX and
+ *     networking stacks, but it is not initialized (normally that is
+ *     done with 'ifconfig DEV up' [or equivalent], which can upload
+ *     firmware and enable communications with the device).
+ *     In this state, the device is powered down and using as less
+ *     power as possible.
+ *     This state is the default after a call to wimax_dev_add(). It
+ *     is ok to have drivers move directly to %WIMAX_ST_UNINITIALIZED
+ *     or %WIMAX_ST_RADIO_OFF in _probe() after the call to
+ *     wimax_dev_add().
+ *     It is recommended that the driver leaves this state when
+ *     calling 'ifconfig DEV up' and enters it back on 'ifconfig DEV
+ *     down'.
+ *
+ * @__WIMAX_ST_QUIESCING: The device is being torn down, so no API
+ *     operations are allowed to proceed except the ones needed to
+ *     complete the device clean up process.
+ *
+ * @WIMAX_ST_UNINITIALIZED: [optional] Communication with the device
+ *     is setup, but the device still requires some configuration
+ *     before being operational.
+ *     Some WiMAX API calls might work.
+ *
+ * @WIMAX_ST_RADIO_OFF: The device is fully up; radio is off (wether
+ *     by hardware or software switches).
+ *     It is recommended to always leave the device in this state
+ *     after initialization.
+ *
+ * @WIMAX_ST_READY: The device is fully up and radio is on.
+ *
+ * @WIMAX_ST_SCANNING: [optional] The device has been instructed to
+ *     scan. In this state, the device cannot be actively connected to
+ *     a network.
+ *
+ * @WIMAX_ST_CONNECTING: The device is connecting to a network. This
+ *     state exists because in some devices, the connect process can
+ *     include a number of negotiations between user space, kernel
+ *     space and the device. User space needs to know what the device
+ *     is doing. If the connect sequence in a device is atomic and
+ *     fast, the device can transition directly to CONNECTED
+ *
+ * @WIMAX_ST_CONNECTED: The device is connected to a network.
+ *
+ * @__WIMAX_ST_INVALID: This is an invalid state used to mark the
+ *     maximum numeric value of states.
+ *
+ * Description:
+ *
+ * Transitions from one state to another one are atomic and can only
+ * be caused in kernel space with wimax_state_change(). To read the
+ * state, use wimax_state_get().
+ *
+ * States starting with __ are internal and shall not be used or
+ * referred to by drivers or userspace. They look ugly, but that's the
+ * point -- if any use is made non-internal to the stack, it is easier
+ * to catch on review.
+ *
+ * All API operations [with well defined exceptions] will take the
+ * device mutex before starting and then check the state. If the state
+ * is %__WIMAX_ST_NULL, %WIMAX_ST_DOWN, %WIMAX_ST_UNINITIALIZED or
+ * %__WIMAX_ST_QUIESCING, it will drop the lock and quit with
+ * -%EINVAL, -%ENOMEDIUM, -%ENOTCONN or -%ESHUTDOWN.
+ *
+ * The order of the definitions is important, so we can do numerical
+ * comparisons (eg: < %WIMAX_ST_RADIO_OFF means the device is not ready
+ * to operate).
+ */
+/*
+ * The allowed state transitions are described in the table below
+ * (states in rows can go to states in columns where there is an X):

+ *
+ *
+ * EXECUTING DEBUGGING ACTIONS OR NOT
+ *
+ * The main thing this framework provides is decission power to take a
+ * debug action (like printing a message) if the current debug level
+ * allows it.
+ *
+ * The decission power is at two levels: at compile-time (what does
+ * not make it is compiled out) and at run-time. The run-time
+ * selection is done per-submodule (as they are declared by the user
+ * of the framework).
+ *
+ * A call to d_test(L) (L being the target debug level) returns true
+ * if the action should be taken because the current debug levels
+ * allow it (both compile and run time).
+ *
+ * It follows that a call to d_test() that can be determined to be
+ * always false at compile time will get the code depending on it
+ * compiled out by optimization.
+ *
+ *
+ * DEBUG LEVELS
+ *
+ * It is up to the caller to define how much a debugging level is.
+ *
+ * Convention sets 0 as "no debug" (so an action marked as debug level 0
+ * will always be taken). The increasing debug levels are used for
+ * increased verbosity.
+ *
+ *
+ * USAGE
+ *
+ * Group the code in modules and submodules inside each module [which
+ * in most cases maps to Linux modules and .c files that compose
+ * those].
+ *
+ *
+ * For each module, there is:
+ *
+ *  - a MODULENAME (single word, legal C identifier)
+ *
+ *  - a debug-levels.h header file that declares the list of
+ *    submodules and that is included by all .c files that use
+ *    the debugging tools. The file name can be anything.
+ *
+ *  - some (optional) .c code to manipulate the runtime debug levels
+ *    through debugfs.
+ *
+ * The debug-levels.h file would look like:
+ *
+ *     #ifndef __debug_levels__h__
+ *     #define __debug_levels__h__
+ *
+ *     #define D_MODULENAME modulename
+ *     #define D_MASTER 10
+ *
+ *     #include <linux/wimax/debug.h>
+ *
+ *     enum d_module {
+ *             D_SUBMODULE_DECLARE(submodule_1),
+ *             D_SUBMODULE_DECLARE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DECLARE(submodule_N)
+ *     };
+ *
+ *     #endif
+ *
+ * D_MASTER is the maximum compile-time debug level; any debug actions
+ * above this will be out. D_MODULENAME is the module name (legal C
+ * identifier), which has to be unique for each module (to avoid
+ * namespace collisions during linkage). Note those #defines need to
+ * be done before #including debug.h
+ *
+ * We declare N different submodules whose debug level can be
+ * independently controlled during runtime.
+ *
+ * In a .c file of the module (and only in one of them), define the
+ * following code:
+ *
+ *     struct d_level D_LEVEL[] = {
+ *             D_SUBMODULE_DEFINE(submodule_1),
+ *             D_SUBMODULE_DEFINE(submodule_2),
+ *             ...
+ *             D_SUBMODULE_DEFINE(submodule_N),
+ *     };
+ *     size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
+ *
+ * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
+ * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
+ * #defined also in this file.
+ *
+ * To manipulate from user space the levels, create a debugfs dentry
+ * and then register each submodule with:
+ *
+ *     result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
+ *     if (result < 0)
+ *            goto error;
+ *
+ * Where PREFIX_ is a name of your chosing. This will create debugfs
+ * file with a single numeric value that can be use to tweak it. To
+ * remove the entires, just use debugfs_remove_recursive() on 'parent'.
+ *
+ * NOTE: remember that even if this will show attached to some
+ *     particular instance of a device, the settings are *global*.
+ *
+ *
+ * On each submodule (for example, .c files), the debug infrastructure
+ * should be included like this:
+ *
+ *     #define D_SUBMODULE submodule_x     // matches one in debug-levels.h
+ *     #include "debug-levels.h"
+ *
+ * after #including all your include files.
+ *
+ *
+ * Now you can use the d_*() macros below [d_test(), d_fnstart(),
+ * d_fnend(), d_printf(), d_dump()].
+ *
+ * If their debug level is greater than D_MASTER, they will be
+ * compiled out.
+ *
+ * If their debug level is lower or equal than D_MASTER but greater
+ * than the current debug level of their submodule, they'll be
+ * ignored.
+ *
+ * Otherwise, the action will be performed.

+ *  - Initial implementation
+ *
+ *
+ * This header defines the data structures and constants used to
+ * communicate with the device.
+ *
+ * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
+ *
+ * The firmware upload protocol is quite simple and only requires a
+ * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
+ * details.
+ *
+ * The BCF data structure is for the firmware file header.
+ *
+ *
+ * THE DATA / CONTROL PROTOCOL
+ *
+ * This is the normal protocol spoken with the device once the
+ * firmware is uploaded. It transports data payloads and control
+ * messages back and forth.
+ *
+ * It consists 'messages' that pack one or more payloads each. The
+ * format is described in detail in drivers/net/wimax/i2400m/rx.c and
+ * tx.c.
+ *
+ *
+ * THE L3L4 PROTOCOL
+ *
+ * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
+ * driver/host software).
+ *
+ * This is the control protocol used by the host to control the i2400m
+ * device (scan, connect, disconnect...). This is sent to / received
+ * as control frames. These frames consist of a header and zero or
+ * more TLVs with information. We call each control frame a "message".
+ *
+ * Each message is composed of:
+ *
+ * HEADER
+ * [TLV0 + PAYLOAD0]
+ * [TLV1 + PAYLOAD1]
+ * [...]
+ * [TLVN + PAYLOADN]
+ *
+ * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
+ * defined by a TLV structure (Type Length Value) which is a 'header'
+ * (struct i2400m_tlv_hdr) and then the payload.
+ *
+ * All integers are represented as Little Endian.
+ *
+ * - REQUESTS AND EVENTS
+ *
+ * The requests can be clasified as follows:
+ *
+ *   COMMAND:  implies a request from the host to the device requesting
+ *             an action being performed. The device will reply with a
+ *             message (with the same type as the command), status and
+ *             no (TLV) payload. Execution of a command might cause
+ *             events (of different type) to be sent later on as
+ *             device's state changes.
+ *
+ *   GET/SET:  similar to COMMAND, but will not cause other
+ *             EVENTs. The reply, in the case of GET, will contain
+ *             TLVs with the requested information.
+ *
+ *   EVENT:    asynchronous messages sent from the device, maybe as a
+ *             consequence of previous COMMANDs but disassociated from
+ *             them.
+ *
+ * Only one request might be pending at the same time (ie: don't
+ * parallelize nor post another GET request before the previous
+ * COMMAND has been acknowledged with it's corresponding reply by the
+ * device).
+ *
+ * The different requests and their formats are described below:
+ *
+ *  I2400M_MT_*   Message types
+ *  I2400M_MS_*   Message status (for replies, events)
+ *  i2400m_tlv_*  TLVs
+ *
+ * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
+ * operation.

+ *
+ *
+ * The WiMAX stack provides an API for controlling and managing the
+ * system's WiMAX devices. This API affects the control plane; the
+ * data plane is accessed via the network stack (netdev).
+ *
+ * Parts of the WiMAX stack API and notifications are exported to
+ * user space via Generic Netlink. In user space, libwimax (part of
+ * the wimax-tools package) provides a shim layer for accessing those
+ * calls.
+ *
+ * The API is standarized for all WiMAX devices and different drivers
+ * implement the backend support for it. However, device-specific
+ * messaging pipes are provided that can be used to issue commands and
+ * receive notifications in free form.
+ *
+ * Currently the messaging pipes are the only means of control as it
+ * is not known (due to the lack of more devices in the market) what
+ * will be a good abstraction layer. Expect this to change as more
+ * devices show in the market. This API is designed to be growable in
+ * order to address this problem.
+ *
+ * USAGE
+ *
+ * Embed a `struct wimax_dev` at the beginning of the the device's
+ * private structure, initialize and register it. For details, see
+ * `struct wimax_dev`s documentation.
+ *
+ * Once this is done, wimax-tools's libwimaxll can be used to
+ * communicate with the driver from user space. You user space
+ * application does not have to forcibily use libwimaxll and can talk
+ * the generic netlink protocol directly if desired.
+ *
+ * Remember this is a very low level API that will to provide all of
+ * WiMAX features. Other daemons and services running in user space
+ * are the expected clients of it. They offer a higher level API that
+ * applications should use (an example of this is the Intel's WiMAX
+ * Network Service for the i2400m).
+ *
+ * DESIGN

+ * Although not set on final stone, this very basic interface is
+ * mostly completed. Remember this is meant to grow as new common
+ * operations are decided upon. New operations will be added to the
+ * interface, intent being on keeping backwards compatibility as much
+ * as possible.
+ *
+ * This layer implements a set of calls to control a WiMAX device,
+ * exposing a frontend to the rest of the kernel and user space (via
+ * generic netlink) and a backend implementation in the driver through
+ * function pointers.
+ *
+ * WiMAX devices have a state, and a kernel-only API allows the
+ * drivers to manipulate that state. State transitions are atomic, and
+ * only some of them are allowed (see `enum wimax_st`).
+ *
+ * Most API calls will set the state automatically; in most cases
+ * drivers have to only report state changes due to external
+ * conditions.
+ *
+ * All API operations are 'atomic', serialized thorough a mutex in the
+ * `struct wimax_dev`.
+ *
+ * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK
+ *
+ * The API is exported to user space using generic netlink (other
+ * methods can be added as needed).
+ *
+ * There is a Generic Netlink Family named "WiMAX", where interfaces
+ * supporting the WiMAX interface receive commands and broadcast their
+ * signals over a multicast group named "msg".
+ *
+ * Mapping to the source/destination interface is done by an interface
+ * index attribute.
+ *
+ * For user-to-kernel traffic (commands) we use a function call
+ * marshalling mechanism, where a message X with attributes A, B, C
+ * sent from user space to kernel space means executing the WiMAX API
+ * call wimax_X(A, B, C), sending the results back as a message.
+ *
+ * Kernel-to-user (notifications or signals) communication is sent
+ * over multicast groups. This allows to have multiple applications
+ * monitoring them.
+ *
+ * Each command/signal gets assigned it's own attribute policy. This
+ * way the validator will verify that all the attributes in there are
+ * only the ones that should be for each command/signal. Thing of an
+ * attribute mapping to a type+argumentname for each command/signal.
+ *
+ * If we had a single policy for *all* commands/signals, after running
+ * the validator we'd have to check "does this attribute belong in
+ * here"?  for each one. It can be done manually, but it's just easier
+ * to have the validator do that job with multiple policies. As well,
+ * it makes it easier to later expand each command/signal signature
+ * without affecting others and keeping the namespace more or less
+ * sane. Not that it is too complicated, but it makes it even easier.
+ *
+ * No state information is maintained in the kernel for each user
+ * space connection (the connection is stateless).
+ *
+ * TESTING FOR THE INTERFACE AND VERSIONING
+ *
+ * If network interface X is a WiMAX device, there will be a Generic
+ * Netlink family named "WiMAX X" and the device will present a
+ * "wimax" directory in it's network sysfs directory
+ * (/sys/class/net/DEVICE/wimax) [used by HAL].
+ *
+ * The inexistence of any of these means the device does not support
+ * this WiMAX API.
+ *
+ * By querying the generic netlink controller, versioning information
+ * and the multicast groups available can be found. Applications using
+ * the interface can either rely on that or use the generic netlink
+ * controller to figure out which generic netlink commands/signals are
+ * supported.
+ *
+ * NOTE: this versioning is a last resort to avoid hard
+ *    incompatibilities. It is the intention of the design of this
+ *    stack not to introduce backward incompatible changes.
+ *
+ * The version code has to fit in one byte (restrictions imposed by
+ * generic netlink); we use `version / 10` for the major version and
+ * `version % 10` for the minor. This gives 9 minors for each major
+ * and 25 majors.
+ *
+ * The version change protocol is as follow:
+ *
+ * - Major versions: needs to be increased if an existing message/API
+ *   call is changed or removed. Doesn't need to be changed if a new
+ *   message is added.
+ *
+ * - Minor version: needs to be increased if new messages/API calls are
+ *   being added or some other consideration that doesn't impact the
+ *   user-kernel interface too much (like some kind of bug fix) and
+ *   that is kind of left up in the air to common sense.
+ *
+ * User space code should not try to work if the major version it was
+ * compiled for differs from what the kernel offers. As well, if the
+ * minor version of the kernel interface is lower than the one user
+ * space is expecting (the one it was compiled for), the kernel
+ * might be missing API calls; user space shall be ready to handle
+ * said condition. Use the generic netlink controller operations to
+ * find which ones are supported and which not.
+ *
+ * libwimaxll:wimaxll_open() takes care of checking versions.
+ *
+ * THE OPERATIONS:
+ *
+ * Each operation is defined in its on file (drivers/net/wimax/op-*.c)
+ * for clarity. The parts needed for an operation are:
+ *
+ *  - a function pointer in `struct wimax_dev`: optional, as the
+ *    operation might be implemented by the stack and not by the
+ *    driver.
+ *
+ *    All function pointers are named wimax_dev->op_*(), and drivers
+ *    must implement them except where noted otherwise.
+ *
+ *  - When exported to user space, a `struct nla_policy` to define the
+ *    attributes of the generic netlink command and a `struct genl_ops`
+ *    to define the operation.
+ *
+ * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>)
+ * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in
+ * include/linux/wimax.h; this file is intended to be cloned by user
+ * space to gain access to those declarations.
+ *
+ * A few caveats to remember:
+ *
+ *  - Need to define attribute numbers starting in 1; otherwise it
+ *    fails.
+ *
+ *  - the `struct genl_family` requires a maximum attribute id; when
+ *    defining the `struct nla_policy` for each message, it has to have
+ *    an array size of WIMAX_GNL_ATTR_MAX+1.
+ *
+ * THE PIPE INTERFACE:
+ *
+ * This interface is kept intentionally simple. The driver can send
+ * and receive free-form messages to/from user space through a
+ * pipe. See drivers/net/wimax/op-msg.c for details.
+ *
+ * The kernel-to-user messages are sent with
+ * wimax_msg(). user-to-kernel messages are delivered via
+ * wimax_dev->op_msg_from_user().
+ *
+ * RFKILL:
+ *
+ * RFKILL support is built into the wimax_dev layer; the driver just
+ * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in
+ * the hardware or software RF kill switches. When the stack wants to
+ * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(),
+ * which the driver implements.
+ *
+ * User space can set the software RF Kill switch by calling
+ * wimax_rfkill().
+ *
+ * The code for now only supports devices that don't require polling;
+ * If the device needs to be polled, create a self-rearming delayed
+ * work struct for polling or look into adding polled support to the
+ * WiMAX stack.
+ *
+ * When initializing the hardware (_probe), after calling
+ * wimax_dev_add(), query the device for it's RF Kill switches status
+ * and feed it back to the WiMAX stack using
+ * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always
+ * report it as ON.
+ *
+ * NOTE: the wimax stack uses an inverted terminology to that of the
+ * RFKILL subsystem:
+ *
+ *  - ON: radio is ON, RFKILL is DISABLED or OFF.
+ *  - OFF: radio is OFF, RFKILL is ENABLED or ON.
+ *
+ * MISCELLANEOUS OPS:
+ *
+ * wimax_reset() can be used to reset the device to power on state; by
+ * default it issues a warm reset that maintains the same device
+ * node. If that is not possible, it falls back to a cold reset
+ * (device reconnect). The driver implements the backend to this
+ * through wimax_dev->op_reset().

+/**
+ * struct wimax_dev - Generic WiMAX device
+ *
+ * @net_dev: [fill] Pointer to the &struct net_device this WiMAX
+ *     device implements.
+ *
+ * @op_msg_from_user: [fill] Driver-specific operation to
+ *     handle a raw message from user space to the driver. The
+ *     driver can send messages to user space using with
+ *     wimax_msg_to_user().
+ *
+ * @op_rfkill_sw_toggle: [fill] Driver-specific operation to act on
+ *     userspace (or any other agent) requesting the WiMAX device to
+ *     change the RF Kill software switch (WIMAX_RF_ON or
+ *     WIMAX_RF_OFF).
+ *     If such hardware support is not present, it is assumed the
+ *     radio cannot be switched off and it is always on (and the stack
+ *     will error out when trying to switch it off). In such case,
+ *     this function pointer can be left as NULL.
+ *
+ * @op_reset: [fill] Driver specific operation to reset the
+ *     device.
+ *     This operation should always attempt first a warm reset that
+ *     does not disconnect the device from the bus and return 0.
+ *     If that fails, it should resort to some sort of cold or bus
+ *     reset (even if it implies a bus disconnection and device
+ *     dissapearance). In that case, -ENODEV should be returned to
+ *     indicate the device is gone.
+ *     This operation has to be synchronous, and return only when the
+ *     reset is complete. In case of having had to resort to bus/cold
+ *     reset implying a device disconnection, the call is allowed to
+ *     return inmediately.
+ *     NOTE: wimax_dev->mutex is NOT locked when this op is being
+ *     called; however, wimax_dev->mutex_reset IS locked to ensure
+ *     serialization of calls to wimax_reset().
+ *     See wimax_reset()'s documentation.
+ *
+ * @name: [fill] A way to identify this device. We need to register a
+ *     name with many subsystems (input for RFKILL, workqueue
+ *     creation, etc). We can't use the network device name as that
+ *     might change and in some instances we don't know it yet (until
+ *     we don't call register_netdev()). So we generate an unique one
+ *     using the driver name and device bus id, place it here and use
+ *     it across the board. Recommended naming:
+ *     DRIVERNAME-BUSNAME:BUSID (dev->bus->name, dev->bus_id).
+ *
+ * @id_table_node: [private] link to the list of wimax devices kept by
+ *     id-table.c. Protected by it's own spinlock.
+ *
+ * @mutex: [private] Serializes all concurrent access and execution of
+ *     operations.
+ *
+ * @mutex_reset: [private] Serializes reset operations. Needs to be a
+ *     different mutex because as part of the reset operation, the
+ *     driver has to call back into the stack to do things such as
+ *     state change, that require wimax_dev->mutex.
+ *
+ * @state: [private] Current state of the WiMAX device.
+ *
+ * @rfkill: [private] integration into the RF-Kill infrastructure.
+ *
+ * @rfkill_input: [private] virtual input device to process the
+ *     hardware RF Kill switches.
+ *
+ * @rf_sw: [private] State of the software radio switch (OFF/ON)
+ *
+ * @rf_hw: [private] State of the hardware radio switch (OFF/ON)
+ *
+ * @debufs_dentry: [private] Used to hook up a debugfs entry. This
+ *     shows up in the debugfs root as wimax:DEVICENAME.
+ *
+ * Description:
+ * This structure defines a common interface to access all WiMAX
+ * devices from different vendors and provides a common API as well as
+ * a free-form device-specific messaging channel.
+ *
+ * Usage:
+ *  1. Embed a &struct wimax_dev at *the beginning* the network
+ *     device structure so that netdev_priv() points to it.
+ *
+ *  2. memset() it to zero
+ *
+ *  3. Initialize with wimax_dev_init(). This will leave the WiMAX
+ *     device in the %__WIMAX_ST_NULL state.
+ *
+ *  4. Fill all the fields marked with [fill]; once called
+ *     wimax_dev_add(), those fields CANNOT be modified.
+ *
+ *  5. Call wimax_dev_add() *after* registering the network
+ *     device. This will leave the WiMAX device in the %WIMAX_ST_DOWN
+ *     state.
+ *     Protect the driver's net_device->open() against succeeding if
+ *     the wimax device state is lower than %WIMAX_ST_DOWN.
+ *
+ *  6. Select when the device is going to be turned on/initialized;
+ *     for example, it could be initialized on 'ifconfig up' (when the
+ *     netdev op 'open()' is called on the driver).
+ *
+ * When the device is initialized (at `ifconfig up` time, or right
+ * after calling wimax_dev_add() from _probe(), make sure the
+ * following steps are taken
+ *
+ *  a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so
+ *     some API calls that shouldn't work until the device is ready
+ *     can be blocked.
+ *
+ *  b. Initialize the device. Make sure to turn the SW radio switch
+ *     off and move the device to state %WIMAX_ST_RADIO_OFF when
+ *     done. When just initialized, a device should be left in RADIO
+ *     OFF state until user space devices to turn it on.
+ *
+ *  c. Query the device for the state of the hardware rfkill switch
+ *     and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw()
+ *     as needed. See below.
+ *
+ * wimax_dev_rm() undoes before unregistering the network device. Once
+ * wimax_dev_add() is called, the driver can get called on the
+ * wimax_dev->op_* function pointers
+ *
+ * CONCURRENCY:
+ *
+ * The stack provides a mutex for each device that will disallow API
+ * calls happening concurrently; thus, op calls into the driver
+ * through the wimax_dev->op*() function pointers will always be
+ * serialized and *never* concurrent.
+ *
+ * For locking, take wimax_dev->mutex is taken; (most) operations in
+ * the API have to check for wimax_dev_is_ready() to return 0 before
+ * continuing (this is done internally).
+ *
+ * REFERENCE COUNTING:
+ *
+ * The WiMAX device is reference counted by the associated network
+ * device. The only operation that can be used to reference the device
+ * is wimax_dev_get_by_genl_info(), and the reference it acquires has
+ * to be released with dev_put(wimax_dev->net_dev).
+ *
+ * RFKILL:
+ *
+ * At startup, both HW and SW radio switchess are assumed to be off.
+ *
+ * At initialization time [after calling wimax_dev_add()], have the
+ * driver query the device for the status of the software and hardware
+ * RF kill switches and call wimax_report_rfkill_hw() and
+ * wimax_rfkill_report_sw() to indicate their state. If any is
+ * missing, just call it to indicate it is ON (radio always on).
+ *
+ * Whenever the driver detects a change in the state of the RF kill
+ * switches, it should call wimax_report_rfkill_hw() or
+ * wimax_report_rfkill_sw() to report it to the stack.

-	  This option creates deprecated symlinks such as the
-	  "device"-link, the <subsystem>:<name>-link, and the
-	  "bus"-link. It may also add deprecated key in the
-	  uevent environment.
-	  None of these features or values should be used today, as
-	  they export driver core implementation details to userspace
-	  or export properties which can't be kept stable across kernel
-	  releases.
-
-	  If enabled, this option will also move any device structures
-	  that belong to a class, back into the /sys/class hierarchy, in
-	  order to support older versions of udev and some userspace
-	  programs.
-
-	  If you are using a distro with the most recent userspace
-	  packages, it should be safe to say N here.
+	  This option switches the layout of sysfs to the deprecated
+	  version.
+
+	  The current sysfs layout features a unified device tree at
+	  /sys/devices/, which is able to express a hierarchy between
+	  class devices. If the deprecated option is set to Y, the
+	  unified device tree is split into a bus device tree at
+	  /sys/devices/ and several individual class device trees at
+	  /sys/class/. The class and bus devices will be connected by
+	  "<subsystem>:<name>" and the "device" links. The "block"
+	  class devices, will not show up in /sys/class/block/. Some
+	  subsystems will suppress the creation of some devices which
+	  depend on the unified device tree.
+
+	  This option is not a pure compatibility option that can
+	  be safely enabled on newer distributions. It will change the
+	  layout of sysfs to the non-extensible deprecated version,
+	  and disable some features, which can not be exported without
+	  confusing older userspace tools. Since 2007/2008 all major
+	  distributions do not enable this option, and ship no tools which
+	  depend on the deprecated layout or this option.
+
+	  If you are using a new kernel on an older distribution, or use
+	  older userspace tools, you might need to say Y here. Do not say Y,
+	  if the original kernel, that came with your distribution, has
+	  this option set to N.

+/*
+
+Goals and Theory of Operation
+
+The primary goal of this feature is to reduce the kernel boot time,
+by doing various independent hardware delays and discovery operations
+decoupled and not strictly serialized.
+
+More specifically, the asynchronous function call concept allows
+certain operations (primarily during system boot) to happen
+asynchronously, out of order, while these operations still
+have their externally visible parts happen sequentially and in-order.
+(not unlike how out-of-order CPUs retire their instructions in order)
+
+Key to the asynchronous function call implementation is the concept of
+a "sequence cookie" (which, although it has an abstracted type, can be
+thought of as a monotonically incrementing number).
+
+The async core will assign each scheduled event such a sequence cookie and
+pass this to the called functions.
+
+The asynchronously called function should before doing a globally visible
+operation, such as registering device numbers, call the
+async_synchronize_cookie() function and pass in its own cookie. The
+async_synchronize_cookie() function will make sure that all asynchronous
+operations that were scheduled prior to the operation corresponding with the
+cookie have completed.
+
+Subsystem/driver initialization code that scheduled asynchronous probe
+functions, but which shares global resources with other drivers/subsystems
+that do not use the asynchronous call feature, need to do a full
+synchronization with the async_synchronize_full() function, before returning
+from their init function. This is to maintain strict ordering between the
+asynchronous and synchronous parts of the kernel.

+ *
+ *
+ * This implements a direct communication channel between user space and

+ *
+ * This is intended for device-specific features, vendor quirks, etc.
+ *
+ * See include/net/wimax.h
+ *
+ * GENERIC NETLINK ENCODING AND CAPACITY
+ *
+ * A destination "pipe name" is added to each message; it is up to the
+ * drivers to assign or use those names (if using them at all).
+ *
+ * Messages are encoded as a binary netlink attribute using nla_put()
+ * using type NLA_UNSPEC (as some versions of libnl still in
+ * deployment don't yet understand NLA_BINARY).
+ *
+ * The maximum capacity of this transport is PAGESIZE per message (so
+ * the actual payload will be bit smaller depending on the
+ * netlink/generic netlink attributes and headers).
+ *
+ * RECEPTION OF MESSAGES
+ *
+ * When a message is received from user space, it is passed verbatim
+ * to the driver calling wimax_dev->op_msg_from_user(). The return
+ * value from this function is passed back to user space as an ack
+ * over the generic netlink protocol.
+ *
+ * The stack doesn't do any processing or interpretation of these
+ * messages.
+ *
+ * SENDING MESSAGES
+ *
+ * Messages can be sent with wimax_msg().
+ *
+ * If the message delivery needs to happen on a different context to
+ * that of its creation, wimax_msg_alloc() can be used to get a
+ * pointer to the message that can be delivered later on with
+ * wimax_msg_send().

-	  This option determines whether the new secmark-based network
-	  controls will be enabled by default.  If not, the old internal
-	  per-packet controls will be enabled by default, preserving
-	  old behavior.
-
-	  If you enable the new controls, you will need updated
-	  SELinux userspace libraries, tools and policy.  Typically,
-	  your distribution will provide these and enable the new controls
-	  in the kernel they also distribute.
-
-	  Note that this option can be overridden at boot with the
-	  selinux_compat_net parameter, and after boot via
-	  /selinux/compat_net.  See Documentation/kernel-parameters.txt
-	  for details on this parameter.
-
-	  If you enable the new network controls, you will likely
-	  also require the SECMARK and CONNSECMARK targets, as
-	  well as any conntrack helpers for protocols which you
-	  wish to control.
