* [net-next 5/8] bna: Add RX State
From: Rasesh Mody @ 2012-12-05 23:01 UTC (permalink / raw)
To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
In-Reply-To: <1354748470-26293-1-git-send-email-rmody@brocade.com>
Change Details:
- BNA state machine for Rx in start_wait state moves it to stop_wait on
receipt of RX_E_STOP. In Rx stop_wait state, on receipt of
RX_E_STARTED event does enet stop
RX_E_STOPPED event does rx_cleanup_cbfn
rx_cleanup_cbfn in this case is called without post_cbfn. post_cbfn
happens only after RX_E_STARTED event is received in start_wait. Without
doing post_cbfn, NAPI remains disabled and in cleanup we try to disable
again causing endless wait. ifconfig process and other workers can thus
get stuck.
- Introducing start_stop_wait state for Rx. This state handles the case of
if post_cbfn is not done simply do stop without the cleanup.

* [net-next 2/8] bna: Tx and Rx Optimizations
From: Rasesh Mody @ 2012-12-05 23:01 UTC (permalink / raw)
To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
In-Reply-To: <1354748470-26293-1-git-send-email-rmody@brocade.com>
Change details:
- Have contiguous queue pages for TxQ, RxQ and CQ. Data structure and
QPT changes related to contiguous queue pages
- Optimized Tx and Rx unmap structures. Tx and Rx fast path changes due to
unmap data structure changes
- Re-factored Tx and Rx fastpath routines as per the new queue data structures
- Implemented bnad_txq_wi_prepare() to program the opcode, flags, frame_len
and num_vectors in the work item
- Reduced Max TxQ and RxQ depth to 2048 while default value for Tx/Rx queue
depth is unaltered (512)

* [net-next 4/8] bna: Rx Page Based Allocation
From: Rasesh Mody @ 2012-12-05 23:01 UTC (permalink / raw)
To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
In-Reply-To: <1354748470-26293-1-git-send-email-rmody@brocade.com>
Change Details:
Enhanced support for GRO. Page-base allocation method for Rx buffers is
used in GRO. Skb allocation has been removed in Rx path to use always warm-cache
skbs provided by napi_get_frags.

* [net-next 3/8] bna: TX Intr Coalescing Fix
From: Rasesh Mody @ 2012-12-05 23:01 UTC (permalink / raw)
To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
In-Reply-To: <1354748470-26293-1-git-send-email-rmody@brocade.com>
Change Details:
For Tx IB, IPM was enabled with inter_pkt_timeo of 0. This caused the
Tx IB not to generate interrupt till inter_pkt_count of packets have been
received. Correct definition for BFI_TX_INTERPKT_TIMEO & BFI_TX_INTERPKT_COUNT

From: Rasesh Mody @ 2012-12-05 23:01 UTC (permalink / raw)

In-Reply-To: <1354748470-26293-1-git-send-email-rmody@brocade.com>
Change details:
- Remove unnecessary prefetch
- Simplify checking & comparison of CQ flags
- Dereference & store unmap_array, unmap_cons & current unmap_array
element only once
- Make structures tx_config & rx_config cache line aligned.

* [net-next 7/8] bna: Firmware Image Naming Change
From: Rasesh Mody @ 2012-12-05 23:01 UTC (permalink / raw)
To: davem, netdev; +Cc: adapter_linux_open_src_team, Rasesh Mody
In-Reply-To: <1354748470-26293-1-git-send-email-rmody@brocade.com>
Change details:
Modified the firmware naming convention to contain the firmware image
version (3.1.0.0). The new convention is <firmware-image>-<firmware-version>.bin
The change will enforce loading only compatible firmware with this driver and
also avoid over-writing the old firmware image in-order to load new version
driver as the firmware names used to be the same.

I'll plug one and see if it went more touchy than usual.
I do not see anything obvious at first sight. Reverting

Any particular sysfs file? I've been grubbing around in there
and I don't see anything that specifies bus width or speed..
Maybe it's some binary blob that needs decoding?
Thanks,

* [PATCH net 1/1] r8169: workaround for missing extended GigaMAC registers
From: Francois Romieu @ 2012-12-05 22:34 UTC (permalink / raw)
To: netdev; +Cc: David Miller, Lee Chun-Yi, Wang YanQing, Hayes Wang
GigaMAC registers have been reported left unitialized in several
situations:
- after cold boot from power-off state
- after S3 resume
Tweaking rtl_hw_phy_config takes care of both.

YanQing and Chun-Yi, can you add your Signed-off-by to this patch ?
It contains bits of everybody's work but it does not match any. :o)
I apparently play in the safe bios league since I did not notice any
difference before or after the patch.
Beware, this patch seems to apply to net-next but doing so moves
rtl_rar_exgmac_set from rtl8168e_2_hw_phy_config to rtl8168f_hw_phy_config.
Hayes, your comments are welcome if any.

You could just as easily have ethtool determine the PCI device
location (using existing facilities) and fetch the PCI-e info from the
PCI sysfs files.
There is no reason to extend ethtool for this.

The custom is long gone (just look at xt_mark.c ;-),
because the module overhead is so much more than a function with
an assignment/readout.

bad example: queue_mapping is tx only. I thought of rxqueues.

I'm happy to do so, but note that that breaks the custom of
having one static struct xt_$NAME for each file xt_$NAME.[ch].
It may be reasonable, as the same issue may keep popping up
as additional sk_buff fields are found useful for filtering. For
instance, skb->queue_mapping could be used in conjuction with
network flow classification (ethtool -N). All the ancillary data
accessible from BPF likely has some use and could be ported
to iptables (rxhash, pkt_type, ...).
To avoid rule explosion, I considered an xt_skbuff match rule that
applies the same mask operation, range and inversion tests, and
takes a field id to select the sk_buff field to operate on. I think
the BPF patch is a better long term solution.

* Should we report bus width/speed via ethtool?
From: Ben Greear @ 2012-12-05 21:35 UTC (permalink / raw)
To: netdev; +Cc: e1000-devel list
It seems the only way to get the current pci-e bus speed & width
in ixgbe (and probably many other NICs) is by parsing output
of lspci -vvv.
I'd personally find it easier if this info were available via
ethtool API.
Any opinions on adding this info? I was thinking something like:
struct ethtool_bus_speed {
u32 cur_speed; /* millions of transactions per sec, or Mhz for older PCI busses */
u32 cur_width; /* bus width */
/* Maximum values supported by NIC */
u32 max_speed;
u32 max_width;
#define BELOW_OPTIMAL_SPEED 0x1 /* Set if NIC cannot run at max speed with current bus settings */
u32 flags;
/* Plenty of space to grow, set to zero until defined */
u32 reserved[32];
};
This could also fit in the reserved space of the
struct ethtool_drvinfo if that were preferred (and
width and flags could be a u16 to save a bit of space
in that case).
Any opinions...or suggestions for other interesting bits to add?
Thanks,
Ben

* ksoftirqd 100% after disabling IPv4 route cache on high pps.
From: 叶雨飞 @ 2012-12-05 21:22 UTC (permalink / raw)
To: Eric Dumazet; +Cc: netdev
Hi Eric,
After disabling the route cache, I found a forwarding performance
problem (inevitable ?). Basically the kernel couldn't keep up under
about 100k pps and ksoftirqd is dominating the CPU. This problem went
away right away if I do
echo 1 > rt_cache_rebuild_count
and comes back as soon as i do echo -1 > rt_cache_rebuild_count.
I then tried to use RPS/RFS to share the load on to mulitple cpus
(since ksoftirqd is only using 1 core, clearly). but that has little
effect.
Is there some tweaks/patches you recommend?
Thanks in advance.
