Is this a physical K80 board, or a virtual one via some sort of cloud provider?

We have nvf0 = GK110, nvf1 = what we call GK110B, but I'm not sure that's an
official name - basically the GTX 780 Ti and related Titans.

We don't have explicit support for nvf2 -- as I understand the K80 (GK210)
actually has some slight differences, e.g. more shared memory, etc... not sure
if that translates into some ctxsw fw differences or if it should just work --
you can check drivers/gpu/drm/nouveau/nvkm/engine/device/base.c, should be easy
to add in 0xf2 support based on the nvf1 if you want to play with it.

Physical K80 board in my possession.  They go for cheap now-a-days on ebay :-)

Memory size (GDDR5): 24GB
CUDA cores: 4992
Number Of GPUs: 2x GK120 GPUs


I'll try adding the nvf2 and see what happens.   I have it in a TB3 enclosure
plugged into my Dell XPS 13, so it makes testing things pretty easy.

That's just really bad. My guess is that the "big-endian" notice is just due to
a register returning all 0xffffffff (we try to flip the GPU into little-endian
mode if we can). Seems like there are issues with the TB enclosure, or
something along those lines.

It does seem like you got further earlier to have gotten the "unknown chipset"
error, but by the time you were running lspci above, they were gone already
(returning all 1's, and PCI is active-low, so that just means it's all off).
Don't know what the difference is, I know nothing about those enclosures. I'd
try to disable any sort of power management that might be turning the enclosure
off.

rebooted without TB3 enclosure attached. Msnuslly loaded nouveau vis insmod
after the TB3 attachment calmed down, and got something a bit cleaner:

So, each GK120 gets 11.5 GiB to make up that 24GiB of ram.

That's not good. BAR1 is unassigned. We want BAR1. This is fallout from the TB
enclosure. I know nothing about this stuff... there are various memory windows,
etc. And apparently we don't fit in the window. I'm guessing there are errors
further up about how there's not enough space to assign those BAR's.

A new motherboard later.. and after enabling 64-bit PCIe stuff the card posts.

Also, wow, BAR1 = 16GB?? Normally it's like 256MB. No wonder your TB setup had
issues.

--- Comment #15 from Alexander von Gluck (kallisti5@unixzen.com) ---
Applied my patch above to ArchLinux (5.11.13-arch1-1) and gave it a whirl.  Got
a little information from nouveou before the system hard locks up.

nouveau 0000:0d:00.0: enabling device (0000 -> 0002)
nouveau 0000:0d:00.0: NVIDIA GK120 (0f22d0a1)
nouveau 0000:0d:00.0: bios: version 80.21.1f.00.01
nouveau 0000:0d:00.0: fb: 11520 MiB GDDR5

(hard crash)

I might get more information from serial... however, ran into an unrelated
issue. Cooling!

The Tesla K80 got up to 175F+ at idle and I had to shut things down. Need to
rig some better cooling solution.
