drm/amdkfd: Fix DQM asserts on Hawaii

2022-01-11T20:44:28+00:00

start_nocpsch would never set dqm->sched_running on Hawaii due to an
early return statement. This would trigger asserts in other functions
and end up in inconsistent states.

drm/amdkfd: add kfd_device_info_init function

2021-12-01T21:15:37+00:00

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.

drm/amdkfd: Retrieve SDMA numbers from amdgpu

2021-11-22T19:46:03+00:00

Instead of hard coding the number of sdma engines and the number of
sdma_xgmi engines in the device_info table, get the number of toal SDMA
instances from amdgpu. The first two engines are sdma engines and the
rest are sdma-xgmi engines unless the ASIC doesn't support XGMI.

v2: add kfd_ prefix to non static function names

drm/amd/amdkfd: Fix kernel panic when reset failed and been triggered again

2021-11-22T19:45:02+00:00

In SRIOV configuration, the reset may failed to bring asic back to normal but stop cpsch
already been called, the start_cpsch will not be called since there is no resume in this
case.  When reset been triggered again, driver should avoid to do uninitialization again.

asic_family was a duplicate of asic_type, both of type amd_asic_type.
