* net-2.6.24 failure with netconsole
From: Andrew Morton @ 2007-08-22 5:54 UTC (permalink / raw)
To: David S. Miller, Stephen Hemminger; +Cc: netdev
Has anyone tested all this new napi stuff with netconsole? It's pretty
disastrous. It immediately goes BUG in napi_enable().
David, there's basically no reason ever why anyone should add BUG() or
BUG_ON() to net code. Please consider rejecting any patches which add new
ones. WARN_ON() is *much* better. It at least gives the user a chance of
getting some disgnostic info out, of performing additional tests or even of
using their kernel if they want to test something else. The only reason to
choose BUG over WARN is if we're actually concerned about scrogging
people's data, or serious things like that (ie: filesystems and mm).
I did this:
--- a/include/linux/netdevice.h~a
+++ a/include/linux/netdevice.h
@@ -328,7 +328,7 @@ static inline void napi_disable(struct n

}

Which enabled me to see this, via netconsole:

Which used to be a BUG. It later oopsed via a null-pointer deref in
net_rx_action(), which is a much preferable result.
config is at http://userweb.kernel.org/~akpm/config-vmm.txt, full dmesg is
below.
This of course renders net-2.6.24 unusable so I'll drop it for now. Please
let me know when it's safe to use again, thanks.

* Re: [RFT] r8169 changes against 2.6.23-rc3
From: Bruce Cole @ 2007-08-22 5:51 UTC (permalink / raw)
To: Francois Romieu, netdev; +Cc: David Gundersen, bacole
In-Reply-To: <46CB3DE4.4060107@gmail.com>
So I did some experimenting with locking, but eventually found that this
chunk:
@@ -2677,10 +2681,18 @@ static void rtl8169_tx_interrupt(struct
net_device *dev,
if (tp->dirty_tx != dirty_tx) {
tp->dirty_tx = dirty_tx;
- - smp_wmb();
- - if (netif_queue_stopped(dev) &&
- - (TX_BUFFS_AVAIL(tp) >= MAX_SKB_FRAGS)) {
- - netif_wake_queue(dev);
+ smp_mb();
+ if (unlikely(netif_queue_stopped(dev))) {
+ netif_tx_lock(dev);
+ if (TX_BUFFS_AVAIL(tp) >= MAX_SKB_FRAGS)
+ netif_wake_queue(dev);
+ if (dirty_tx != tp->cur_tx)
+ RTL_W8(TxPoll, NPQ);
+ netif_tx_unlock(dev);
+ } else if (dirty_tx != tp->cur_tx) {
+ netif_tx_lock(dev);
+ RTL_W8(TxPoll, NPQ);
+ netif_tx_unlock(dev);
}
}
}
from the patch in http://www.spinics.net/lists/netdev/msg33960.html
was sufficient to fix the stuck TX queue bug without the busy-wait.
Actually
just the else portion of the above chunk was sufficient in my testing,
without
the barrier change or the if statement change.
David Gundersen pointed me to this potential fix days ago, but I didn't
consider it first since the change had (presumably intentionally) been
dropped from
the set of diffs Francois pointed me to. Given that I had reported the same
problem as David Gundersen (and Dirk, and other samba users...) I
thought this
patch had been ruled out. Apparently not. Hopefully this can be dusted off
and made into a fairly high priority fix as it has been biting realtek users
since last year at least.

I'm not making any suggestions, so don't read that into anything I've
said :-)
I think the jury is still out, but seeing TSO perform even slightly
worse with the batching changes in place would be very worrysome.
This applies to both throughput and cpu utilization.

I am planning to do more testing on your suggestion over the
weekend, but I had a comment. Are you saying that TSO and
batching should be mutually exclusive so hardware that doesn't
support TSO (like IB) only would benefit?
But even if they can co-exist, aren't cases like sending
multiple small skbs better handled with batching?

* [PATCH 4/11 RESEND] cxgb3 - Expose HW memory page info
From: Divy Le Ray @ 2007-08-22 3:49 UTC (permalink / raw)
To: jeff; +Cc: netdev, linux-kernel, swise
From: Divy Le Ray <divy@chelsio.com>
A HW issue requires limiting the receive window size
to 23 pages of internal memory.
These pages can be configured to different sizes,
thus the RDMA driver needs to know the
page size to enforce the upper limit.
Also assign explicit enum values.

From: Divy Le Ray <divy@chelsio.com>
Send small TX_DATA work requests as immediate data even when
there are fragments. this avoids doing multiple DMAs for
small fragmented packets.
The driver already implements this optimization for small
contiguous packets.

Jeff,
I'm resubmitting the last cxgb3 patch series against netdev-2.6#upstream,
minus the first patch that you already applied and the last patch.
Here is a brief description:
- Modify max HW Rx coalescing size
- Log SGE doorbell Fifo overflow
- Use Tx immediate data for offload packets whenever possible
- RDMA can get internal mem info to workaround HW issues
- More validity checks on connection ids
- Stop MAC when a fatal error is detected
- Log HW serial number
- Update internal mem operating mode
- Update engine microcode management, version is now 1.1.0
- Update FW management, version is now 4.6.0
- Ignore some HW errors until the HW is initialized
Cheers,
Divy

From: Ishizaki Kou @ 2007-08-22 0:27 UTC (permalink / raw)
To: Linas Vepstas; +Cc: netdev, cbe-oss-dev, arnd
We must not call netif_poll_enable after enabling interrupts,
because an interrupt might come in and set the __LINK_STATE_RX_SCHED
bit before we get to clear that bit again. If that happens,
the next call to the ->poll() function will oops.

As you pointed out, we intended that "[PATCH] spidernet: improve
interrupt handling" solves the same problem which Arnd's patch solves.
When spider_net_open() is called, interrupt reasons sometimes remain
on interrupt status register, even though they are masked by mask
register. With this patch, spider_net_interrupt() compares the value
of interrupt status register with SPIDER_NET_INTX_MASK_VALUE, not with
interrupt mask register value. As a result, spider_net_interrupt()
(which is called from request_irq() in spider_net_open()) starts
polling and causes BUG_ON().
So, netif_poll_enable() must be called before request_irq() is
called. This is the reason that we also need Arnd's patch.
Best regards,
Kou Ishizaki

The per cpu backlog napi struct can't do netpoll and has the
dev member set to NULL. Fixes an oops on boot when netpoll is
enabled.

We've tried that, sort of. See the mess surrounding the whole
extern/static/inline/__whatever boondogle, which seems to have
changed semantics in every single gcc release since 2.95 or so.
And recently mention was made that gcc4.4 will have *new* semantics
in this area. Yee. Hah.

Pages have chunked up considerably in recent years.
Just bringing up a myspace page can give you megabytes of video,

* [PATCH 2/3] sky2: only bring up watchdog if link is active
From: Stephen Hemminger @ 2007-08-21 21:34 UTC (permalink / raw)
To: Jeff Garzik; +Cc: netdev
In-Reply-To: <20070821213401.543412708@linux-foundation.org>
[-- Attachment #1: sky2-timer-power.patch --]
[-- Type: text/plain, Size: 4909 bytes --]
This fixes the extra timer overhead that people were whining about
as a 2.6.23 regression.
Running the watchdog timer all the time is unneeded. Change it
to run only if link is up, and reduce frequency to save power.
