drm/amdkfd: CRIU implement gpu_id remapping2022-02-07T22:59:52+00:00David Yat Sindavid.yatsin@amd.com2021-04-09T16:30:43+00:00urn:sha1:bef153b70c6e3594b849d44a23f806328b9c68d4
When doing a restore on a different node, the gpu_id's on the restore
node may be different. But the user space application will still refer
use the original gpu_id's in the ioctl calls. Adding code to create a
gpu id mapping so that kfd can determine actual gpu_id during the user
ioctl's.

Initializes kfd->device_info given either asic_type (enum) if GFX
version is less than GFX9, or GC IP version if greater. Also takes in vf
and the target compiler gfx version. Uses SDMA version to determine
num_sdma_queues_per_engine.
Convert device_info to a non-pointer member of kfd, change references
accordingly.
Change unsupported asic condition to only probe f2g, move device_info
initialization post-switch.
