Tune the sleep interval in the PSP fence wait loop from 10-100us to 30-100us. This adjustment results in an overall wait window of 600ms (30us * 20000 iterations) to 2 seconds (100us * 20000 iterations), which guarantees that we can retrieve the correct fence value Signed-off-by: Ce Sun <[email protected]> --- drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c index b0540b009e84..b08a57a07331 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c @@ -735,7 +735,7 @@ psp_cmd_submit_buf(struct psp_context *psp, ras_intr = amdgpu_ras_intr_triggered(); if (ras_intr) break; - usleep_range(10, 100); + usleep_range(30, 100); amdgpu_device_invalidate_hdp(psp->adev, NULL); } -- 2.34.1
