Comment 1 Thomas Leroy 2022-01-19 14:50:05 UTC

I can't find signs of "NVGPU_IOCTL_CHANNEL_SET_ERROR_NOTIFIER" in our sources, so again, probably NVIDIA stuff

Comment 2 Takashi Iwai 2022-01-19 16:23:03 UTC

Agreed, it must be Nvidia downstream stuff.

Comment 3 Thomas Leroy 2022-01-19 17:29:56 UTC
