====================
net/macb: add TX multiqueue support for gem
ChangeLog
v3:
- reduce the number of added #define in macb.h
- simplify the queue initialization
- add some more comments
- use "hw_q" index when dealing with the hardware queue mask and "q" index for
linux (software) queue index in "for" loops
v2:
fix compilation warnings for netdev_vdbg("%u...", queue - bp->queues, ...) calls
v1:
At the first look this patch may look quite big but it cannot be splitted.
Each queue has its own dedicated IRQ, which should be handled.
Also the Transmit Base Queue Pointer register of each available queue must be
initialized before starting the transmission, otherwise the transmission will be
halted immediately as HRESP errors are likely to occur.
In addition, some fields had to be moved from struct macb into struct macb_queue
so a common code could manage the queues.
This patch was applied to net-next and tested on a sama5d36ek board, which embeds
both macb and gem IPs, to check the backward compatibility.
Also it was tested on a sama5dx FPGA platform with a gem designed to use 3 queues.
Then we used the tc program to set a queue discipline policy as describe in the
Documentation/networking/multiqueue.txt: we successfully used each queue.

gem devices designed with multiqueue CANNOT work without this patch.
When probing a gem device, the driver must first prepare and enable the
peripheral clock before accessing I/O registers. The second step is to read the
MID register to find whether the device is a gem or an old macb IP.
For gem devices, it reads the Design Configuration Register 6 (DCFG6) to
compute to total number of queues, whereas macb devices always have a single
queue.
Only then it can call alloc_etherdev_mq() with the correct number of queues.
This is the reason why the order of some initializations has been changed in
macb_probe().
Eventually, the dedicated IRQ and TX ring buffer descriptors are initialized
for each queue.
For backward compatibility reasons, queue0 uses the legacy registers ISR, IER,
IDR, IMR, TBQP and RBQP. On the other hand, the other queues use new registers
ISR[1..7], IER[1..7], IDR[1..7], IMR[1..7], TBQP[1..7] and RBQP[1..7].
Except this hardware detail there is no real difference between queue0 and the
others. The driver hides that thanks to the struct macb_queue.
This structure allows us to share a common set of functions for all the queues.
Besides when a TX error occurs, the gem MUST be halted before writing any of
the TBQP registers to reset the relevant queue. An immediate side effect is
that the other queues too aren't processed anymore by the gem.
So macb_tx_error_task() calls netif_tx_stop_all_queues() to notify the Linux
network engine that all transmissions are stopped.
Also macb_tx_error_task() now calls spin_lock_irqsave() to prevent the
interrupt handlers of the other queues from running as each of them may wake
its associated queue up (please refer to macb_tx_interrupt()).
Finally, as all queues have previously been stopped, they should be restarted
calling netif_tx_start_all_queues() and setting the TSTART bit into the Network
Control Register. Before this patch, when dealing with a single queue, the
driver used to defer the reset of the faulting queue and the write of the
TSTART bit until the next call of macb_start_xmit().
As explained before, this bit is now set by macb_tx_error_task() too. That's
why the faulting queue MUST be reset by setting the TX_USED bit in its first
buffer descriptor before writing the TSTART bit.
Queue 0 always exits and is the lowest priority when other queues are available.
The higher the index of the queue is, the higher its priority is.
When transmitting frames, the TX queue is selected by the skb->queue_mapping
value. So queue discipline can be used to define the queue priority policy.

This patch set fixes cxgb4i's tx credit calculation and adds handling of
additional rx message and negative advice types. It also removes the duplicate
code in cxgb4i to set the outgoing queues of a packet.
Karen Xie (7):
cxgb4i: fix tx immediate data credit check
cxgb4i: fix credit check for tx_data_wr
cxgb4/cxgb4i: set max. outgoing pdu length in the f/w
cxgb4i: add more types of negative advice
cxgb4i: handle non pdu-aligned rx data
cxgb4i: use cxgb4's set_wr_txq() for setting outgoing queues
libcxgbi: fix the debug print accessing skb after it is freed
Sending to net as the fixes are mostly in the network area and it touches
cxgb4's header file (t4fw_api.h).
v2 corrects the "CHECK"s flagged by checkpatch.pl --strict.
v3 splits the 3rd patch from v2 to two separate patches. Adds detailed commit
messages and makes subject more concise. Patch 3/6 also changes the return
value of is_neg_adv() from int to bool.
v4 -- please ignore.
v5 splits the 1st patch from v3 to two separate patches and reduces code
duplication in make_tx_data_wr().
v6 removed the code style cleanup in the 2nd patch. The style update will be
addressed in a separate patch.
v7 updates the 7th patch with more detailed commit message.
v8 removes the duplicate subject lines from the message bodies.
v9 reformatted the commit messages to be max. 80 characters per line.
v10 rebased to net-next tree.

When building the bcmgenet driver as module, I get:
ERROR: "fixed_phy_register" [drivers/net/ethernet/broadcom/genet/genet.ko] undefined!
commit b0ba512e225d72 ("net: bcmgenet: enable driver to work without device

needs to be exported if used from a module.

This patch addresses an issue with the level compression of the fib_trie.
Specifically in the case of adding a new leaf that triggers a new node to
be added that takes the place of the old node. The result is a trie where
the 1 child tnode is on one side and one leaf is on the other which gives
you a very deep trie. Below is the script I used to generate a trie on
dummy0 with a 10.X.X.X family of addresses.
ip link add type dummy
ipval=184549374
bit=2
for i in `seq 1 23`
do
ifconfig dummy0:$bit $ipval/8
ipval=`expr $ipval - $bit`
bit=`expr $bit \* 2`
done
cat /proc/net/fib_triestat
Running the script before the patch:
Local:
Aver depth: 10.82
Max depth: 23
Leaves: 29
Prefixes: 30
Internal nodes: 27
1: 26 2: 1
Pointers: 56
Null ptrs: 1
Total size: 5 kB
After applying the patch and repeating:
Local:
Aver depth: 4.72
Max depth: 9
Leaves: 29
Prefixes: 30
Internal nodes: 12
1: 3 2: 2 3: 7
Pointers: 70
Null ptrs: 30
Total size: 4 kB
What this fix does is start the rebalance at the newly created tnode
instead of at the parent tnode. This way if there is a gap between the
parent and the new node it doesn't prevent the new tnode from being
coalesced with any pre-existing nodes that may have been pushed into one
of the new nodes child branches.

Since the real device can segment packets by software, a vlan device
can set TSO/UFO even when the real device doesn't have those features.
Unlike GSO, this allows packets to be segmented after Qdisc.

If a touchpad reports the F11 data40 register then this indicates that the touchpad reports
additional ACM (Accidental Contact Mitigation) data after the F11 data in the HID attention
report. These additional bytes shift the position of the F30 button data causing the driver
to incorrectly report button state when this functionality is present. This patch accounts
for the additional data in the report.

Before ->start() is called, bufsize size is set to HID_MIN_BUFFER_SIZE,
64 bytes. While processing the IRQ, we were asking to receive up to
wMaxInputLength bytes, which can be bigger than 64 bytes.
Later, when ->start is run, a proper bufsize will be calculated.
Given wMaxInputLength is said to be unreliable in other part of the
code, set to receive only what we can even if it results in truncated
reports.

This change enables the sunvdc driver to reconnect and recover if a vds
service domain is disconnected or bounced.
By default, it will wait indefinitely for the service domain to become
available again, but will honor a non-zero vdc-timout md property if one
is set. If a timeout is reached, any in-progress I/O's are completed
with -EIO.

Pull workqueue update from Tejun Heo:
"Work items which may be involved in memory reclaim path may be
executed by the rescuer under memory pressure. When a rescuer gets
activated, it processes whatever are on the pending list and then goes
back to sleep until the manager kicks it again which involves 100ms
delay.
This is problematic for self-requeueing work items or the ones running
on ordered workqueues as there always is only one work item on the
pending list when the rescuer kicks in. The execution of that work
item produces more to execute but the rescuer won't see them until
after the said 100ms has passed, so such workqueues would only execute
one work item every 100ms under prolonged memory pressure, which BTW
may be being prolonged due to the slow execution.
Neil wrote up a patch which fixes this issue by keeping the rescuer
working as long as the target workqueue is busy but doesn't have
enough workers"
* 'for-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq:
workqueue: allow rescuer thread to do more work.
workqueue: invert the order between pool->lock and wq_mayday_lock
workqueue: cosmetic update in rescuer_thread()
