GM206 support?

GM206 support?

[Andy Lutomirski]

My new GTX 960 (GM206, I think) says:

[   10.329351] nouveau ![  DEVICE][0000:09:00.0] unknown Maxwell chipset
[   10.329355] nouveau E[  DEVICE][0000:09:00.0] unknown chipset, 0x126010a1
[   10.329356] nouveau E[     DRM] failed to create 0x00000080, -22
[   10.330129] nouveau: probe of 0000:09:00.0 failed with error -22

Hacking up nouveau so that it treats it like a GM204 doesn't work.
Are there any near-term plans to support this card?

Thanks,
Andy

What happens if you just drop the 0x126 next to the 0x124 in
engine/device/gm100.c ?

> Are there any near-term plans to support this card?

I don't know of anyone with the hw... maybe Ben got one? If you're
interested in helping, the kernel logs from the above experiment + an
mmiotrace of the blob drivers (see
https://wiki.ubuntu.com/X/MMIOTracing) + vbios (see
http://nouveau.freedesktop.org/wiki/DumpingVideoBios/).

I assume you're on a recent kernel? You need 3.19 for the GM204 stuff
to work in the first place.

Hi Ilia,

Neither 3.19 nor 4.0-rcsomething works.

I put an mmio trace (X startup and glxgears) and a vbios dump here:

Stefan sent proper patches to get nouveau going on his GM206, which
will make it into the next 4.0-rc. Here is a tree that is destined
towards drm-fixes:

http://cgit.freedesktop.org/nouveau/linux-2.6/log/?h=linux-4.0

Let us know if it makes the card work. (Definitely no acceleration
without signed firmware for now though.)

The driver loads and seems to work.  The nouveau X driver doesn't load, though.

I tried to use the nvidia firmware:

with:

in my modprobe configuration, and that made no obvious difference,
even in the kernel logs.

Excellent!

Yeah, xf86-video-nouveau has no support for the GM20x family? Note
that even if it did load, you wouldn't get any acceleration -- may as
well just use the 'xf86-video-modesetting' driver.

Right, that's expected. GM20x requires signed firmware. We haven't
even gotten as far as being able to figure out what all the
*proprietary* firmware is, never mind even loading it. It doesn't show
up in mmiotraces, probably read by the card directly out of system
memory. It's a multi-stage process, complicating RE. The firmware that
you've extracted is exclusively for video decoding acceleration. You
could extract firmware from 325.15 which will include the pgraph fuc
blobs too [which would get loaded by NvGrUseFW=1], but nothing that'll
help you.

Hi guys,
i did sent a patch to add GM206 to the ddx also but looks like it got missed you can find it here.

http://lists.freedesktop.org/archives/nouveau/2015-February/020144.html

But as said no acceleration yet.

I'll ping in that older mail-thread as probably mail was overlooked (probably i should have mentioned ddx in my subject)

Stefan

I'll probably stick with the binary driver until there's acceleration.
I have too many pixels on my monitor for reasonable unaccelerated
compositing performance, I think.

Thanks for bringing this up, though!  Working modesetting is a *huge*
improvement over vesafb.

This is something that the recent work done by Samuel could help. He
got the nvidia driver to work in kvm and then managed to trace the
MMIO operations. If the card really reads the fw from system memory,
it should show up in his trace.
