2010-10-28rapidio: fix destructive port EM initialization for Tsi568Alexandre Bounine1-5/+10
Replace possibly damaging broadcast writes into the per-port SP_MODE registers with individual writes for each port. This will preserve individual port configurations in case if ports are configured differently.

2010-10-28rapidio: add handling of redundant routesAlexandre Bounine3-51/+54
Detects RIO link to the already enumerated device and properly sets links between device objects. Changes to the enumeration/discovery logic: 1. Use Master Enable bit to signal end of the enumeration - agents may start their discovery process as soon as they see this bit set (Component Tag register was used before for this purpose). 2. Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.

2010-10-28rapidio: fix RapidIO sysfs hierarchyAlexandre Bounine2-1/+2
This set of RapidIO patches extends support for standard error recovery mechanism and adds new IDT Gen2 sRIO switch devices - CPS-1848 and CPS-1616. Implementation of the standard error-stopped state recovery mechanism (as defined by the RapidIO specification) is required for the new switches. Version 2 of this set of patches addresses received comments and fixes an error notification setup issue found in the idt_gen2.c after the first version was released.

2007-07-12sysfs: add parameter "struct bin_attribute *" in .read/.write methods for ↵Zhang Rui1-2/+4
sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

2007-07-12sysfs: kill unnecessary attribute->ownerTejun Heo1-1/+0
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-11[PATCH] rapidio: fix multi-switch enumerationAlexandre Bounine1-31/+87
This patch contains two fixes for RapisIO enumeration logic: 1. Fix enumeration in configurations with multiple switches. The patch adds: a. Enumeration of an empty switch. Empty switch is a switch that does not have any endpoint devices attached to it (except host device or previous switch in a chain). New code assigns a phony destination ID associated with the switch and sets up corresponding routes. b. Adds a second pass to the enumeration to setup routes to devices discovered after switch was scanned. 2. Fix enumeration failure when riohdid parameter has non-zero value. Current version fails to setup response path to the host when it has destination ID other that 0.

2006-06-28[PATCH] spin/rwlock init cleanupsIngo Molnar1-2/+2
locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-01-09[PATCH] fix more missing includesTim Schmielau3-0/+4
Include fixes for 2.6.14-git11. Should allow to remove sched.h from module.h on i386, x86_64, arm, ia64, ppc, ppc64, and s390. Probably more to come since I haven't yet checked the other archs.
