Subject: nouveau : fix r570 suspend/resume regression
Date: Tue, 3 Feb 2026 15:21:10 +1000 [thread overview]
Message-ID: <20260203052431.2219998-1-airlied@gmail.com> (raw)
Since R570 firmware got enabled, a number of GPUs have not being
successfully suspend/resuming. Lyude showed it on RTX6000, which
I reproduced and wasted a lot of time down various rabbit holes.
There are two required fixes, the first one adds proper sequence
numbers to the rpc messages, which fixes a bunch of NOCAT asserts.
Then we have to pass the runtime vs non-runtime state down to the
GSP fbsr code. This however requires replacing a bool with an enum
which refactors quite a bunch of interfaces unfortunately, but it
was the cleanest way to do it.
The final patch hooks up the interface so normal suspend doesn't
set the GCOFF flags.
Dave.
