I occasionally hit fatal errors when working on OpenCL with the official CTS, but that's on Pascal. I could give your patches a go once I move my main development machine over to Turing and report if I still trigger problems nouveau isn't able to recover from. But yeah, generally the CTS is able to cause bigger issues for me at least. > Alistair Popple (5): > drm/nouveau: Fix MMU fault interrupts on Turing > drm/nouveau: Remove Turing interrupt hack > drm/nouveau: Move Turing specific FIFO functions > drm/nouveau: FIFO interrupt fixes for Turing > drm/nouveau: Turing channel preemption fix > > .../gpu/drm/nouveau/nvkm/engine/fifo/gk104.c | 46 +-- > .../gpu/drm/nouveau/nvkm/engine/fifo/gk104.h | 32 ++ > .../gpu/drm/nouveau/nvkm/engine/fifo/tu102.c | 364 +++++++++++++++++- > .../gpu/drm/nouveau/nvkm/subdev/fault/tu102.c | 21 +- > drivers/gpu/drm/nouveau/nvkm/subdev/mc/base.c | 3 - > drivers/gpu/drm/nouveau/nvkm/subdev/mc/priv.h | 1 - > .../gpu/drm/nouveau/nvkm/subdev/mc/tu102.c | 113 +++++- > 7 files changed, 529 insertions(+), 51 deletions(-) > > -- > 2.20.1 > > _______________________________________________ > Nouveau mailing list > Nouveau@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/nouveau > _______________________________________________ Nouveau mailing list Nouveau@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/nouveau
