[9fans] intel ethernet

[lejatorn]

Hi all,

My problem is I can't have the network up on my laptop; I get a
message stating there is no /net/ether0 when I try to ip/ipconfig
for example. According to the wiki, that means the ethernet card in my
laptop does not seem to be supported under plan9.

Given it's an intel gigabit pro/1000 (which is supposed to be supported)
I found it surprising, so I tried to force the use of the igbe/igbepcie
drivers with an entry in plan9.ini but to no avail.

Am I missing something here? Or is it just that my specific chipset
(it's a 82566MM) is not yet supported by these drivers? 
If yes, how hard would it be to have it so? Where should I start to do
that?

Thanks,
Mathieu.

please send the output of the pci command. It could be something as
simple as a devid change, which intel loves to do all the time.

Re: [9fans] intel ethernet

[erik quanstrom]

i missed your 82566mm in my previous
post.  ron's speculation is basically right.
intel change device ids between the initial
documentation and the actual product.
in /sys/src/9/pc/ether82563.c makee this change
and recompile a kernel:

			break;
		case 0x1049:		/* mm */
+ 		case 0x1047:
		case 0x104a:		/* dm */
		case 0x104d:		/* v */
			type = i82566;
			break;
		case 0x10a4:
		case 0x105e:

i'll submit a patch.

Re: [9fans] intel ethernet

[lejatorn]

Thx, but as I told you in pv, I can't test if that works since any
kernel I build with that change (which I don't think is the cause)
freezes in the same way I described in the other thread (about iso not
booting on T61). Even in pata mode.
I tried building from the sources which had been installed by the iso I
used (from 07/12/07) to install originally. I also tried with the
sources from an iso from 22/12/07; same problem.
I'm currently getting the latest iso, but I don't think it should be
pretty different from the one of 22th of Dec, shouldn't it?

I will attach the pci -v output in a mail in the other thread.

Any idea?

Mathieu.

I don't see 1047 in the pci output.

I have a similar laptop (thinkpad R61i) with the same NIC. Installed
Plan 9 from the latest ISO and the driver doesn't seem to work.

Right, you have this:

        1049  82566MM Gigabit Network Connection

And it's clearly covered in the driver. Hmm.

what do you get when you cat /dev/drivers

Ok, I meant lejatorn's pci output didn't have 1047 either. Maybe I wasn't clear.

Anyway, here is /dev/drivers:

	#p proc

Re: [9fans] intel ethernet

[Mathieu Lonjaret]

 Hmm, sorry for being such a noob in decoding those logs, but where do
you see whether or not I have 1047?
Anyway, it's not even my main issue since I can't boot on any other
kernel than the one which is already installed.
So even if adding the 1047 to the driver is the solution to the
network part, I won't even be able to try it...

Re: [9fans] intel ethernet

[erik quanstrom]

the missing device was vid 8088 did 1047, i believe.

- erik

p.s. /dev/drivers is something unrelated.  all ethernet
are #l devices.  they are sort of a sub device thing.

Re: [9fans] intel ethernet

[Mathieu Lonjaret]

ah nevermind the first question, now I indeed see the "net" line with 1049...

Re: [9fans] intel ethernet

[erik quanstrom]

ah, i understand the problem now.

i subitted a patch for this some time ago. the unusable CLS
message is from the driver.  it's checking for cache line size.  an
anacronism from the pci driver.  pcie does not really have the
concept of cache line size, though the vestigal register remains.
the fix is to remobe any reference to cls in the driver and recompile.

- erik

Re: [9fans] intel ethernet

[erik quanstrom]

okay.  contact me off list with details.  especially what is
printed before it freezes.  this may be due to a bug in 9load.
there's a patch submitted.

- erik

Re: [9fans] intel ethernet

[lejatorn]

Yes, there is that but there is also an ethernet 82566MM card, that's
what I'm talking about.
