Title:
DOE Discovery Issues
Status in linux-nvidia package in Ubuntu:
Triaged
Bug description:
We see the following DOE errors when booting systems with certain
NVIDIA GPUs:
kernel: pci 0009:01:00.0: DOE: [2c8] ABORT timed out
kernel: pci 0009:01:00.0: DOE: [2c8] failed to reset mailbox with abort
command : -5
kernel: pci 0009:01:00.0: DOE: [2c8] failed to create mailbox: -5
Newer generation GPUs do support DOE, but only using DOE discovery v2.
Add this support by cherry-picking the following patch:
