10 years agonet: tx scalability works : trans_start
Eric Dumazet [Mon, 18 May 2009 03:55:16 +0000]
net: tx scalability works : trans_start

struct net_device trans_start field is a hot spot on SMP and high performance
devices, particularly multi queues ones, because every transmitter dirties
it. Is main use is tx watchdog and bonding alive checks.

But as most devices dont use NETIF_F_LLTX, we have to lock
a netdev_queue before calling their ndo_start_xmit(). So it makes
sense to move trans_start from net_device to netdev_queue. Its update
will occur on a already present (and in exclusive state) cache line, for
free.

We can do this transition smoothly. An old driver continue to
update dev->trans_start, while an updated one updates txq->trans_start.

Further patches could also put tx_bytes/tx_packets counters in
netdev_queue to avoid dirtying dev->stats (vlan device comes to mind)

10 years agobnx2: bnx2_tx_int() optimizations
Eric Dumazet [Tue, 12 May 2009 20:48:02 +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)

tun: add tun_flags, owner, group attributes in sysfs

This patch adds three attribute files in /sys/class/net/$dev/ for tun
devices; allowing userspace to obtain the information which TUNGETIFF
offers, and more, but without having to attach to the device in question
(which may not be possible if it's in use).

It also fixes a bug which has been present in the TUNGETIFF ioctl since
its inception, where it would never set IFF_TUN or IFF_TAP according to
the device type. (Look carefully at the code which I remove from

as we hadn't sent up to catch the interrupt that event caused.

This patch checks for this failure in:
ixgbe_probe - So we can log the failure asap. We check right after we
set up the adapter->flags, which is when we know that we have a fan.
ixgbe_up_complete - To catch failures that may have happened between probe
and when we set up the interrupt that would normally detect the fan failure.

To enable all of this we need to initialize the adapter flag with
IXGBE_FLAG_FAN_FAIL_CAPABLE when the NIC contained a fan.

bnx2: Fix panic in bnx2_poll_work().

Add barrier() to bnx2_get_hw_{tx|rx}_cons() to fix this issue:

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
6843: 3d ff 00 00 00        cmp    $0xff,%eax

Traditionally Intel based NIC drivers request I/O port even though it

Intel PCIE 10Gb driver (ixgbe) also requests I/O port but it doesn't

This is a little inconvenient situation because sometimes we have to

ixgbe: make q_vectors dynamic to reduce netdev size

Currently the q_vectors are being allocated statically inside of the
adapter struct.  This increases the overall size of the adapter struct when
we can easily allocate the vectors dynamically.  This patch changes that
behavior so that the q_vectors are allocated dynamically and the napi
structures are automatically allocated inside of the q_vectors as needed.

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.

Jouni Malinen [Tue, 5 May 2009 17:35:14 +0000]
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
whether there are any frames remaining in the reorder buffer if no new
frames are received.
