[PATCH v4] drm/amdgpu: Add xcc param to SRIOV kiq write and WREG32_SOC15_IP_NO_KIQ (v4)

Tue Oct 31 16:56:56 UTC 2023


WREG32/RREG32_SOC15_IP_NO_KIQ and amdgpu_virt_kiq_reg_write_reg_wait
are not using the correct rlcg interface or mec engine, respectively.

Add xcc instance parameter to them.

v4: Use GET_INST and squash commit with:
"drm/amdgpu: Add xcc_inst param to amdgpu_virt_kiq_reg_write_reg_wait"

v3: xcc not needed for MMMHUB

v2: rebase
