GeForce(R) GT 710 1GB PCIE x 1 on arm64

[Milan Buška]

[-- Attachment #1.1: Type: text/plain, Size: 808 bytes --]

Hi to all.
I'm experimenting with running a
https://www.zotac.com/us/product/graphics_card/geforce%C2%AE-gt-710-1gb-pcie-x-1
card on an Nvidia Jetson TX2 arm64 device.
Possible?
Linux kernel aarch64 5.6.10.
Because Nvidia did not list drivers for this architecture, I'm
experimenting with a nouveau driver.
The Jetson TX2 has a default driver for the host1x framebuffer for output
from the board via HDMI.
I changed the video kernel parameter to nouveau. Booting the system OK only
there is no output on the monitor.
The device can only be controlled via the serial console.
Can anyone advise me where to start setting up - (if something needs to be
set up)

Greeting

Milan Buška

In general it should be possible. If you're having issues, please include dmesg.

One issue that has come up is that the PCIe controllers on such boards
have very narrow memory windows, not enough to map certain (required)
BARs of NVIDIA GPUs (or other GPUs, I'd expect). This comes up in
dmesg with PCI-related errors.

Cheers,

Hm, I can't say that I've ever seen that "2-byte config write" errors.
However it does appear to have assigned the BARs correctly, so there's
that.

So that "core notifier timeout" and subsequent GPU lockup indicate
that something's amiss. Most of the initialization was able to be
completed, including reading EDID from your monitor (hence the
non-default resolution), but we're not seeing values change properly /
missing notifications. I'm actually wondering if we aren't
initializing the GPU because we think it's already initialized. Could
you boot with nouveau.config=NvForcePost=1 and see if that helps?

Hm, looks like we should be passing in TTM_PL_FLAG_UNCACHED for the
notifier, which should cause nouveau_bo to do the right thing (by
setting force_coherent=true in this environment):

ret = nouveau_bo_new(&drm->client, 4096, 0x1000, TTM_PL_FLAG_VRAM,
     0, 0x0000, NULL, NULL, &disp->sync);

Milan - can you try changing that line in

drivers/gpu/drm/nouveau/dispnv50/disp.c::nv50_display_create

to have TTM_PL_FLAG_VRAM | TTM_PL_FLAG_UNCACHED instead for that
nouveau_bo_new call (no need to change the later nouveau_bo_pin call)?

Cheers,

Oh well, it was worth a shot. Someone will have to debug what's going on.

Good day.
I'm not a programmer, so I don't understand.

Just a question:
What's wrong =>
=> nouveau driver
=> pcie driver
=> graphics card

It will help me save unnecessary lost time.

Most likely the issue is in nouveau. There's a much smaller likelihood
that the issue is with e.g. the iommu/dma-api implementation.

I don't think that logic has changed in over a year, nor do I expect
it will in the future, unless someone comes in and does the work to
figure out what's wrong. If that's not you, then you have to hope
there will be someone else interested in running a desktop GPU on an
arm-based board.

Re: GeForce(R) GT 710 1GB PCIE x 1 on arm64

[Milan Buška]

Maybe there are more of us trying to get our hands

expand considerably.
And we also have to look at the energy aspect.
Overall, this model can reduce energy consumption.
