From 85150626ea0423fd0adb5ac9b5ab4bbaff9aa30b Mon Sep 17 00:00:00 2001 From: Victor Lu Date: Tue, 3 Oct 2023 16:15:52 -0400 Subject: drm/amdgpu: Use correct KIQ MEC engine for gfx9.4.3 (v5) 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 use the new xcc_id parameter. Using amdgpu_sriov_runtime to determine whether to access via kiq or RLC is sufficient for now. v5: add condition in amdgpu_device_xcc_w/rreg, remove trace func call v4: avoid using amdgpu_sriov_w/rreg 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 Signed-off-by: Victor Lu Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h index 7088c5015675..f23bafec71c5 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h @@ -521,8 +521,8 @@ int amdgpu_gfx_process_ras_data_cb(struct amdgpu_device *adev, int amdgpu_gfx_cp_ecc_error_irq(struct amdgpu_device *adev, struct amdgpu_irq_src *source, struct amdgpu_iv_entry *entry); -uint32_t amdgpu_kiq_rreg(struct amdgpu_device *adev, uint32_t reg); -void amdgpu_kiq_wreg(struct amdgpu_device *adev, uint32_t reg, uint32_t v); +uint32_t amdgpu_kiq_rreg(struct amdgpu_device *adev, uint32_t reg, uint32_t xcc_id); +void amdgpu_kiq_wreg(struct amdgpu_device *adev, uint32_t reg, uint32_t v, uint32_t xcc_id); int amdgpu_gfx_get_num_kcq(struct amdgpu_device *adev); void amdgpu_gfx_cp_init_microcode(struct amdgpu_device *adev, uint32_t ucode_id); -- cgit
