Re: IGB driver upgrade

[sbs]

Hello guys.

Is it possible to upgrade intel gigabit adapter's e1000 driver to
2.2.9? This is the latest version according to Intel website.


I've got a problem with 2.1.0-k2 drivers statically compiled into kernel.

Surely I can download drivers from intel and compile it as module, but
I need to compile it statically
Intel drivers do not provide sources for static compilation :(

Is it possible to upgrade drivers to igb-2.2.9 in the source tree and
allow the static compilation of them?

Because having 2.1.0-k2 we experience some strange random freezes with
network interface which can be fixed only by restarting network.

2.2.9 module has no such problems but we need to use static kernels
according to our policy.

I assume you are referring to the igb driver since that is what is in 
the subject and not the e1000 driver correct?

Normally the upstream driver should be up to date with any fixes that 
are in the standalone module.  What version of the kernel are you 
currently running?  Also have your tried testing the older standalone 
igb modules to see if the same issues exist there in either igb 2.1.9 or 
  igb 2.0.6?  This would help us to determine what changes in the 
standalone module might be missing from the in-kernel version of the driver.

I have CCed our e1000-devel list.  In the future you may want to CC this 
list as it will provide better visibility to the Intel wired networking 
maintainers.

We're running 2.6.33.2 kernel version.
I have compiled and installed 2.0.6 and 2.1.9 modules on two our servers.

Strange freezes usually appears in several (1 or 2) days.
So I'll let you know when it happen and what module version will be
responsible for that

Since the issue is being seen with the in-kernel driver and not the 
standalone module one other possibility is that this could be an issue 
that is specific to multi-queue.  You can test for this by setting the 
RSS parameter to 0 for the standalone module to enable multiple queues 
on the 2.2.9 driver.

One other thing you might want to try would be to test the latest 
release candidate kernel from kernel.org.  This would help to tell us if 
this is still an issue in the current kernel, or an issue that is 
present in just 2.6.33.

Thanks,

Alex

I have tested 2.0.6 and 2.1.9 modules for 4 days and there were no any
issues detected :)

Thank you, I'll install 2.6.35-rc4 today on several servers with both
standalone(with RSS=0) and static driver and let you know after.

Re: IGB driver upgrade

i have tested next configurations for several days:

standalone 2.2.9 driver with 2.6.35-rc4 and RSS=0
standalone 2.2.9 driver with 2.6.33.2 and RSS=0
statically linked driver with 2.6.35-rc4 kernel

all three configurations had no any problems.
seems that IGB was fixed in 35-rc4.

gonna try 2.6.34.1 with static drivers tomorrow night.
