* [RESEND/patch 2.6.25-rc2-git] net/enc28j60: low power mode
From: David Brownell @ 2008-02-19 20:54 UTC (permalink / raw)
To: netdev; +Cc: Claudio Lanconelli
In-Reply-To: <47AAE7CD.9050801@eptar.com>
Keep enc28j60 chips in low-power mode when they're not in use.
At typically 120 mA, these chips run hot even when idle; this
low power mode cuts that power usage by a factor of around 100.
This version provides a generic routine to poll a register until
its masked value equals some value ... e.g. bit set or cleared.
It's basically what the previous wait_phy_ready() did, but this
version is generalized to support the handshaking needed to
enter and exit low power mode.

Minor bugfixes to the enc28j60 driver ... wrong section marking,
indentation, and bogus use of spi_bus_type. There's still major
overuse of printk; essentially every place it's used should switch
to dev_*() messaging primitives.

Karl, you could try kernel 2.6.24(.2) which AFAIU features the mentioned
changes.

Update: when I revert Herbert's patch in addition to applying your
patch, the iSCSI performance goes back up to 115 MB/s again in both
directions. So it looks like turning off SG for TX didn't itself cause
the performance drop, but rather that the performance drop is just
another manifestation of whatever bug is causing the data corruption.
I do not regularly use wireshark or look at network packet dumps, so I
am not really sure what to look for. Given the above information, do
you still believe that there is value in examining the packet dump?

I send here my proposal: it's intended for testing and to check one of
possible solutions here. IMHO your lockdep reports show there is no
use to change anything around sk_dst_lock: it would need the global
change of this lock to fix this problem. So the fix should be done
around pch->upl lock and this means changing ppp_generic.
In the patch below I've used trylock in places which seem to allow
for skipping some things (while config is changed only) or simply
don't need this lock because there is no ppp struct. This could be
modified to add some waiting loop if necessary. Another option is to
change the write side of this lock: it looks like more vulnerable if
something missed because there are more locks involved, but probably
should be enough to solve this problem too.
I think pppol2tp need to be first checked only with hlist_lock bh
patch, unless there were some lockdep reports on these other locks
too. (BTW, I added ppp maintainer to CC - I hope we get Paul's opinion
on this.)
Regards,
Jarek P.

Hum, you are right, kmem_cache_free() doesnt allow a NULL object, like kfree()

Can you confirm whether you're getting TCP checksum errors on the other
side that is receiving packets from the 5701? You can just check
statistics using netstat -s. I suspect that after we turn off SG,
checksum is no longer offloaded and we are getting lots of TCP checksum
errors instead that are slowing the performance.

* [RTNL]: Add missing link netlink attribute policy definitions

To: davem; +Cc: netdev
IFLA_LINK is no longer a write-only attribute on the kernel
side and must thus be validated. Same goes for the newly
introduced IFLA_LINKINFO.
Fixes undefined behaviour if either of the attributes are
not well formed.

Kernel panic - not syncing: Fatal exception in interrupt
The issue was originally noticed on 2.6.20.21 machines, when we had ~60
servers all panic at the same time after a switch went crazy.
To reproduce download linkloop
http://freshmeat.net/projects/linkloop/
then run linkloop -d -s 1000 <target mac>

The netdev maintainer, Jeff Garzik (to whom you should submit your
driver), frowns upon the use of bitfields, and for good reason. See,
for example,
http://marc.info/?l=linux-kernel&m=118444531031506&w=2
http://lkml.org/lkml/2005/8/5/361
http://lkml.org/lkml/2006/6/20/470
http://en.wikipedia.org/wiki/Bit_field.
You should avoid them if at all possible.

Hi Tony. Can you give us the output of :
sudo lspci -vvv -xxxx -s 03:01.0'
(assuming that is still the correct address of the 3Com NIC.)
Also, after some digging, I found that the 5701 can run into trouble if
a 64-bit DMA read terminates early and then completes as a 32-bit transfer.
The problem is reportedly very rare, but the failure mode looks like a
match. Can you apply the following patch and see if it helps your
performance / corruption problems?

Interesting. So the workload that regressed is mostly RX with a
little TX traffic? Can you try to reproduce this with something
like netperf to eliminate other variables?
This is all very puzzling since the patch in question shouldn't
change an RX load at all.

I tested it with 32bit 2.6.25-rc1 on 8-core stoakley. The result almost has no difference
between pure kernel and patched kernel.
New update: On 8-core stoakley, the regression becomes 2~3% with kernel 2.6.25-rc2. On
tigerton, the regression is still 30% with 2.6.25-rc2. On Tulsa( 8 cores+hyperthreading),
the regression is still 4% with 2.6.25-rc2.
With my patch, on tigerton, almost all regression disappears. On tulsa, only about 2%
regression disappears.
So this issue is triggerred with multiple-cpu. Perhaps process scheduler is another
factor causing the issue to happen, but it's very hard to change scheduler.
Eric,
I tested your new patch in function loopback_xmit. It has no improvement, while it doesn't
introduce new issues. As you tested it on dual-core machine and got improvement, how about
merging your patch with mine?

Thanks very much Yanmin, I think we can apply your patch as is, if no
regression was found for 32bits.

No, thank you, that was an experiment and is not related to your findings on
dst_entry.
I am currently working on a 'distributed refcount' infrastructure, to be able
to spread on several nodes (for NUMA machines) or several cache lines (normal
SMP machines) the high pressure we currently have on some refcnt (struct
dst_entry, struct net_device, and many more refcnts ...)
Instead of NR_CPUS allocations, goal is to be able to restrict to a small
value like 4, 8 or 16 the number of 32bits entities used to store one refcnt,
even if NR_CPUS=4096 or so.
atomic_inc(&p->refcnt) -> distref_inc(&p->refcnt)
distref_inc(struct distref *p)
{
atomic_inc(myptr[p->offset]);
}

If some patch works for you, and you can show here its advantages,
you should probably add here some link and request for merging.
BTW, I wonder if you tried to check if changing CONFIG_HZ makes any
difference here?
