drm/amd: Don't reset dGPUs if the system is going to s2idle

2022-05-18T19:24:35+00:00

An A+A configuration on ASUS ROG Strix G513QY proves that the ASIC reset for handling aborted suspend can't work with s2idle. This functionality was introduced in commit daf8de0874ab5b ("drm/amdgpu: always reset the asic in suspend (v2)"). A few other commits have gone on top of the ASIC reset, but this still doesn't work on the A+A configuration in s2idle. Avoid doing the reset on dGPUs specifically when using s2idle.

drm/amdgpu: Add use_xgmi_p2p module parameter

2022-02-24T22:25:12+00:00

This parameter controls xGMI p2p communication, which is enabled by default. However, it can be disabled by setting it to 0. In case xGMI p2p is disabled in a dGPU, PCIe p2p interface will be used instead. This parameter is ignored in GPUs that do not support xGMI p2p configuration.
