drm/amdgpu/vce1: Workaround PLL timeout on FirePro W9000

2025-11-12T02:54:19+00:00

Sometimes the VCE PLL times out waiting for CTLACK/CTLACK2. When it happens, the VCE still works, but much slower. Observed on a Tahiti GPU, but not all: - FirePro W9000 has the issue - Radeon R9 280X not affected - Radeon HD 7990 not affected As a workaround, on the affected chip just don't put the VCE PLL in sleep mode. Leaving the VCE PLL in bypass mode or reset mode both work. Using bypass mode is simpler. Signed-off-by: Timur Kristóf Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu/vce1: Enable VCE1 on Tahiti, Pitcairn, Cape Verde GPUs

2025-11-12T02:54:18+00:00

Add the VCE1 IP block to the SI GPUs that have it. Advertise the encoder capabilities corresponding to VCE1, so the userspace applications can detect and use it.

drm/amdgpu: wire up defines, shifts and masks through SI code

2025-04-07T19:18:32+00:00

To be able to remove as much duplicated defines, the different files containing definitions, shifts and masks must be properly included. Once done, the code will be migrated where needed to shifts and masks and proper defines, before removing useless defines in the end. Signed-off-by: Alexandre Demers Signed-off-by: Alex Deucher

drm/amdgpu: prepare DCE6 uniformisation with DCE8 and DCE10

2025-03-11T16:36:42+00:00

Let's begin the cleanup in sid.h to prevent warnings and errors when wiring sid.h into dce_v6_0.c. This is a bigger cleanup. Many defines found under sid.h have already been properly moved into the different "_d.h" and "_sh_mask.h", so they should have been already removed from sid.h and properly linked in where needed.
