This patch enables per-queue and per-pipe reset functionality for GFX IP v9.5.0 when using MEC firmware version 21 (0x15) or later.
This change: 1. Refactors the pipe reset support check in gfx_v9_4_3_pipe_reset_support() to use the compute_supported_reset flags instead of hardcoding version checks. 2. Adds support for GFX9.5.0 (IP 9.5.0) with MEC firmware version >= 21 to enable per-queue and per-pipe reset capabilities. v2: Replaced mec version check with !!(adev->gfx.compute_supported_reset & AMDGPU_RESET_TYPE_PER_PIPE) (Lijo) Signed-off-by: Asad Kamal <[email protected]> Signed-off-by: Jesse Zhang <[email protected]> --- drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c b/drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c index 9db2bde5c59d..e6d516b1efd9 100644 --- a/drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c +++ b/drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c @@ -1153,6 +1153,12 @@ static int gfx_v9_4_3_sw_init(struct amdgpu_ip_block *ip_block) adev->gfx.compute_supported_reset |= AMDGPU_RESET_TYPE_PER_PIPE; } break; + case IP_VERSION(9, 5, 0): + if (adev->gfx.mec_fw_version >= 21) { + adev->gfx.compute_supported_reset |= AMDGPU_RESET_TYPE_PER_QUEUE; + adev->gfx.compute_supported_reset |= AMDGPU_RESET_TYPE_PER_PIPE; + } + break; default: break; } @@ -3452,9 +3458,7 @@ static int gfx_v9_4_3_unmap_done(struct amdgpu_device *adev, uint32_t me, static bool gfx_v9_4_3_pipe_reset_support(struct amdgpu_device *adev) { - /*TODO: Need check gfx9.4.4 mec fw whether supports pipe reset as well.*/ - if (amdgpu_ip_version(adev, GC_HWIP, 0) == IP_VERSION(9, 4, 3) && - adev->gfx.mec_fw_version >= 0x0000009b) + if (!!(adev->gfx.compute_supported_reset & AMDGPU_RESET_TYPE_PER_PIPE)) return true; else dev_warn_once(adev->dev, "Please use the latest MEC version to see whether support pipe reset\n"); -- 2.49.0
