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.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c index a2a29dcb2422..b9674c57c436 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c @@ -931,12 +931,12 @@ void amdgpu_gfx_ras_error_func(struct amdgpu_device *adev, func(adev, ras_error_status, i); } -uint32_t amdgpu_kiq_rreg(struct amdgpu_device *adev, uint32_t reg) +uint32_t amdgpu_kiq_rreg(struct amdgpu_device *adev, uint32_t reg, uint32_t xcc_id) { signed long r, cnt = 0; unsigned long flags; uint32_t seq, reg_val_offs = 0, value = 0; - struct amdgpu_kiq *kiq = &adev->gfx.kiq[0]; + struct amdgpu_kiq *kiq = &adev->gfx.kiq[xcc_id]; struct amdgpu_ring *ring = &kiq->ring; if (amdgpu_device_skip_hw_access(adev)) @@ -999,12 +999,12 @@ failed_kiq_read: return ~0; } -void amdgpu_kiq_wreg(struct amdgpu_device *adev, uint32_t reg, uint32_t v) +void amdgpu_kiq_wreg(struct amdgpu_device *adev, uint32_t reg, uint32_t v, uint32_t xcc_id) { signed long r, cnt = 0; unsigned long flags; uint32_t seq; - struct amdgpu_kiq *kiq = &adev->gfx.kiq[0]; + struct amdgpu_kiq *kiq = &adev->gfx.kiq[xcc_id]; struct amdgpu_ring *ring = &kiq->ring; BUG_ON(!ring->funcs->emit_wreg); -- cgit
