drm/amdkfd: drop struct kfd_cu_info

2023-10-03T19:41:13Z

I think this was an abstraction back from when kfd supported both radeon and amdgpu. Since we just support amdgpu now, there is no more need for this and we can use the amdgpu structures directly. This also avoids having the kfd_cu_info structures on the stack when inlining which can blow up the stack.

drm/amdgpu: Store CU info from all XCCs for GFX v9.4.3

2023-09-11T21:10:19Z

Currently, we store CU info only for a single XCC assuming that it is the same for all XCCs. However, that may not be true. As a result, store CU info for all XCCs. This info is later used for CU masking. Signed-off-by: Mukul Joshi Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: use correct method to get clock under SRIOV

2023-08-30T18:59:21Z

[What] Current SRIOV still using adev->clock.default_XX which gets from atomfirmware. But these fields are abandoned in atomfirmware long ago. Which may cause function to return a 0 value. [How] We don't need to check whether SR-IOV. For SR-IOV one-vf-mode, pm is enabled and VF is able to read dpm clock from pmfw, so we can use dpm clock interface directly. For multi-VF mode, VF pm is disabled, so driver can just react as pm disabled. One-vf-mode is introduced from GFX9 so it shall not have any backward compatibility issue.
