[PATCH 3/5] drm/amdgpu: Use correct KIQ MEC engine for gfx9.4.3 (v3)
Victor Lu
victorchengchi.lu at amd.com
Wed Oct 25 20:52:40 UTC 2023
amdgpu_kiq_wreg/rreg is hardcoded to use MEC engine 0.
Add an xcc_id parameter to amdgpu_kiq_wreg/rreg, define W/RREG32_XCC
and amdgpu_device_xcc_wreg/rreg to to use the new xcc_id parameter.
v3: use W/RREG32_XCC to handle non-kiq case
v2: define amdgpu_device_xcc_wreg/rreg instead of changing parameters
of amdgpu_device_wreg/rreg
