I've been wondering if we want to switch the default value
of DRM_NOUVEAU_GSP_DEFAULT to y for the nouveau kernel module. My
impression is that at this point the GSP code path is both much better
tested and much faster than the classic firmware code paths on turing
and ampere. I think that encouraging distributions to use GSP by default
will go a long way to improving the default experience for users.
Thoughts? Is there any reason not to do this?
Yes please :)
When the GSP did not bring anything to users because the userspace was
unable to really make use of it, I think it made sense to keep it disabled.
The situation has however changed quite drastically and at this point,
not using the GSP has a big impact on usability. And users who do not
wish to depend on a proprietary firmware can always use
`nouveau.config=NvGspRm=0` to disable it (if they can't find a Kepler
GPU that would be supported using only open source firmware).
I would however appreciate better error reporting when loading the GSP
fails, as it can currently be quite unhelpful without increasing the
drm log verbosity:
[ 2.177205] nouveau 0000:01:00.0: gsp ctor failed: -2
