15 years agobnx2: bnx2_tx_int() optimizations
Eric Dumazet [Tue, 12 May 2009 20:48:02 +0000 (20:48 +0000)]
bnx2: bnx2_tx_int() optimizations

When using bnx2 in a high transmit load, bnx2_tx_int() cost is pretty high.

There are two reasons.

One is an expensive call to bnx2_get_hw_tx_cons(bnapi) for each freed skb

One is cpu stalls when accessing skb_is_gso(skb) / skb_shinfo(skb)->nr_frags
because of two cache line misses.
(One to get skb->end/head to compute skb_shinfo(skb),
 one to get is_gso/nr_frags)

This patch :

1) avoids calling bnx2_get_hw_tx_cons(bnapi) too many times.

2) makes bnx2_start_xmit() cache is_gso & nr_frags into sw_tx_bd descriptor.
   This uses a litle bit more ram (256 longs per device on x86), but helps a lot.

3) uses a prefetch(&skb->end) to speedup dev_kfree_skb(), bringing
  cache line that will be needed in skb_release_data()

result is 5 % bandwidth increase in benchmarks, involving UDP or TCP receive
 & transmits, when a cpu is dedicated to ksoftirqd for bnx2.

bnx2_tx_int going from 3.33 % cpu to 0.5 % cpu in oprofile

Note : skb_dma_unmap() still very expensive but this is for another patch,
not related to bnx2 (2.9 % of cpu, while it does nothing on x86_32)

http://bugzilla.kernel.org/show_bug.cgi?id=12698

This issue was reported by multiple i386 users.  Without barrier(),
the compiled code looks like the following where %eax contains the
address of the tx_cons or rx_cons in the DMA status block.  The
status block contents can change between the cmpb and the movzwl
instruction.  The driver would crash if the value was not 0xff during
the cmpb instruction, but changed to 0xff during the movzwl
instruction.

6828: 80 38 ff              cmpb   $0xff,(%eax)
682b: 0f b7 10              movzwl (%eax),%edx

With the added barrier(), the compiled code now looks correct:

683d: 0f b7 10              movzwl (%eax),%edx
6840: 0f b6 c2              movzbl %dl,%eax

wimax: oops: wimax_dev_add() is the only one that can initialize the state

When a new wimax_dev is created, it's state has to be __WIMAX_ST_NULL
until wimax_dev_add() is succesfully called. This allows calls into
the stack that happen before said time to be rejected.

Until now, the state was being set (by mistake) to UNINITIALIZED,
which was allowing calls such as wimax_report_rfkill_hw() to go
through even when a call to wimax_dev_add() had failed; that was
causing an oops when touching uninitialized data.

This situation is normal when the device starts reporting state before
the whole initialization has been completed. It just has to be dealt
with.

mac80211: Add a timeout for frames in the RX reorder buffer

This patch allows skbs to be released from the RX reorder buffer in
case they have been there for an unexpectedly long time without us
having received the missing frames before them. Previously, these
frames were only released when the reorder window moved and that could
take very long time unless new frames were received constantly (e.g.,
TCP connections could be killed more or less indefinitely).

This situation should not happen very frequently, but it looks like
there are some scenarious that trigger it for some reason. As such,
this should be considered mostly a workaround to speed up recovery
from unexpected siutation that could result in connections hanging for
long periods of time.

The changes here will only check for timeout situation when adding new
RX frames to the reorder buffer. It does not handle all possible
cases, but seems to help for most cases that could result from common
network usage (e.g., TCP retrying at least couple of times). For more
completely coverage, a timer could be used to periodically check

frames are received.

 fixed this by only allowing standard channels to be registered so
 now hostapd works as expected.

 * Docs (and HAL source) say that we must write 0 on timer0 when

 a few times, beacon inteval seems to change from 100ms to a sec
 (we get one beacon per sec).

 * We need to set sleep timers on STA mode and enable power saving +
 support PCF.

 ...but i think it's time we enable AP support "officialy" so that

 * Increase bmiss threshold to 10, that's what we used on MadWiFi for
 a long time. Also when we have pending frames on the beacon queue (we
 got a beacon that didn't make it on the air) it's more likely that
 the beacon queue never started, probably due to faulty DBA setting,
 so change that "beacon queue didn't stop" message.

 Tested this with AP mode and IBSS mode and seems to work fine ;-)

 (conected the cards using attenuators). I also switched between
 various tx power levels and i saw an equal power change on the remote
