Lite-On ethernet controller

Lite-On ethernet controller

[Josh Huber]

I have what appears to be a Lite-On ethernet controller, which is supported
by the tulip driver. What it really is, is a Asante FriendlyNET card. I had
heard that the card works in 2.2.14+, but I'm having trouble getting it to
work in later kernels (devel).

Because of the network driver interface change, I can't try out the newest
tulip driver in 2.4pre.  Does anyone know of forward-ported tulip drivers?

The particular error I'm seeing only happens with moderate load -- pings and
other light traffic work 100%.

Error information:
NETDEV WATCHDOG: eth1: transmit timed out
Transmit timed out, status e4660000, CSR12 000050ca, resetting...

Device information:
tulip driver output:
eth1: Lite-On PNIC-II rev 37 at 0x1c00, 00:00:94:C5:EF:FF, IRQ 30.
lspci -vv output attached because it's too wide.

Any ideas?

I don't understand what you mean here.

A tulip driver exists in the 2.4pre kernel.  Are you having problems
with that driver?

IRQ 30?  Is that ok for PPC?

Sorry I wasn't clear.

The Tulip driver in the devel kernels is not working for me. Supposedly,
this card works with the driver in later 2.2 kernels.  I can't get 2.2.x to
boot on this machine I have, which is why I'm using 2.4 pre versions.

What I meant by the newer tulip driver was the version available from Don
Becker's tulip development page.

Yes, here's the output from /proc/interrupts:
              CPU0
     1:       1820   i8259         keyboard

    31:       6377   OpenPIC       aic7xxx

eth0 is an actual DEC tulip card, which works great.

Heh, sorry.  I'll attach it this time.

Yes, actually there are systems that are not limited to 8 IRQs cascaded
into another 8 IRQs ;-))

Seriously, IIRC, desktop PPC systems have at least one interrupt
controller with 32 IRQs. Some even have more... or more controllers.

The IO port region above might be your problem. What machine type is
this? Do you have any ISA slots in your machine? Form the i8259
interrupt controller I deduce it's not a PowerMac...

Have you looked at the driver whether it runs on IO ports or
memory-mapped? Since the two regions above probably represent different
views on the same register file, I'd go memory-mapped (i.e. using region
1 above), if possible.

Josh is not the only one having problems...

I have a Digital DC21041 Tulip rev 33 at 0x1080, 21041 mode, 00:80:C8:5A:F8:5B,
IRQ 29. The interrupt number is correct :-) I occasionally got random network
lock ups with the old dex45 driver (tulip didn't work then) that could be
solved by rebooting only (ifconfig down locked up the machine).

Later the card seemed to work fine with the updated tulip driver, as you
probably remember.  However, I just got a problem with the updated driver
(2.3.99-pre3) for the first time:

| NETDEV WATCHDOG: eth0: transmit timed out
| eth0: 21041 transmit timed out, status fc660010, CSR12 000002c8, CSR13 ffffef0d, CSR14 fffff73d, resetting...
| eth0: 21143 100baseTx sensed media.
        ^^^^^
	Huh? I have a real 21041.

So I ran `tulip-diag -fa' and got:

I hope this helps. Thanks for your time!

Note that Josh is using a similar box as me, a CHRP LongTrail. In fact all
people with LongTrails seem to have problems with Tulip chips. So it might be a
motherboard problem.

After updating to the newer tulip driver in the devel kernels, my problems
with my real tulip card went away.  I've been having trouble getting two
other cards working however -- the lite-on card that I mentioned before, and
another tulip clone (Kingston).  The kingston card was much worse -- it
dropped ~30% of packets under light load, and completely locked up under
medium-heavy load.

Yeah, which would be unfortunate... :(

That would REALLY suck because I was looking forward to throwing my PNIC
and PNIC II test cards into this old PMac 7200 which I use for testing
drivers on PPC.  If it is a general endian bug in the PNIC* codepath,
testing there should hopefully expose the problem.

If not, I have a feeling Josh and I will be exchanging e-mail... :)

It's not a powermac...it's a CHRP Longtrail board.  Geert's board has an ISA
slot, and I believe mine has all the hardware for an ISA slot, except the
actual slot was removed.

Geert, how did you get the tulip-diag program to compile on your chrp
machine?  I'd like to give it a try and see what it tells me.

How would I check this?  Perhaps Jeff knows this? :)

What's the next step for debugging this?

Now, as for possible buggy motherboards, wouldn't other PCI devices have
trouble?  Perhaps network cards just show the problem becuase of the high
interrupt delivery rate?

I've got other PCI cards in this machine, and haven't had any trouble with
them:

I/O port is OK, since the card does work most of the time.

CHRP LongTrail has ISA. Interrupts are controlled by an OpenPIC master, and the
traditional dual i8259 cascade as a slave.

By pathing it to map ISA I/O space :-) I mailed the patch to you.
