Tulip driver broken on Cobalt RaQ1 in 2.6

Tulip driver broken on Cobalt RaQ1 in 2.6

[Martin Michlmayr]

[-- Attachment #1: Type: text/plain, Size: 2156 bytes --]

We have Debian users who happily used 2.4.27 on their Cobalt Raq1 and
Qube 2700.  However, since we moved to 2.6 these machines stopped
working.  I found out that the network driver (tulip) is no longer
working on these machines.  Today I tried to track down when this
started to happen but I couldn't find a 2.6 release where it actually
worked.

The 2.4.27 release we have is based on Peter Horton's patches from
http://www.colonel-panic.org/cobalt-mips/  Today I tested current git,
and 2.6.18 (which work out of the box), as well as 2.6.12-rc2 and
2.6.16-rc1 with Peter's patches.  In all of these releases, network
would work fine on a RaQ2, but not on a RaQ1.  I'm not sure what
information to report because I found nothing obvious.  In 2.4.27, we
get:

PCI: Enabling device 00:07.0 (0045 -> 0047)
tulip0: Old format EEPROM on 'Cobalt Microserver' board.  Using substitute media control info.
tulip0:  EEPROM default media type Autosense.
tulip0:  Index #0 - Media MII (#11) described by a 21142 MII PHY (3) block.
tulip0:  MII transceiver #1 config 1000 status 7809 advertising 01e1.
eth0: Digital DS21143 Tulip rev 65 at 0x100000, 00:10:E0:00:27:5C, IRQ 4.

wheras 2.6.16-rc1 has:

PCI: Enabling device 0000:00:07.0 (0041 -> 0043)
tulip0: Old format EEPROM on 'Cobalt Microserver' board.  Using substitute media control info.
tulip0:  EEPROM default media type Autosense.
tulip0:  Index #0 - Media MII (#11) described by a 21142 MII PHY (3) block.
tulip0:  MII transceiver #1 config 1000 status 7809 advertising 01e1.
eth0: Digital DS21143 Tulip rev 65 at b0001000, 00:10:E0:00:27:5C, IRQ 20.

The address is different but I doubt this makes a difference because the
RaQ2 shows the same difference and here networking works.  I also noticed
the following in the boot logs of the RaQ1 with 2.6 that doesn't happen
with 2.4, but that's because 2.4 doesn't have such a warning:

Galileo: revision 2
Galileo: PCI retry count exceeded (06.0)

Does anyone who knows about Cobalt hardware have any idea where to look?
I'm happy to send boot logs and test patches if someone wants to
investigate this problem.

Have you diffed the two versions against eachother, for the memory  
address its running uncached. Check io-remapping.

What error occurs on Raq1?

I cannot find this line in current git.
Do you apply any patch for Debian kernel?

There is no error, but I never get a DHCP response:

It's in arch/mips/cobalt/irq.c

This is a pristine kernel from git (well, I had to apply your patch to
get IDE going).

What does /proc/interrupts show after this ?

Does the networking work in CoLo ?

The "PCI retry count" thing is a red herring. There's no device at 06.0 
so that's why you get the message. The kernel used to explicitly skip 
this device when PCI retries were disabled otherwise it would hang. When 
I enabled the PCI retry counter there was no need to skip it, you just 
get the debug.

Yes.
