drm/amdgpu: enable freesync for A+A configs

2021-02-02T22:36:33Z

Some newer APUs can scanout directly from GTT, that saves us from allocating another bounce buffer in VRAM and enables freesync in such configurations. Without this patch creating a framebuffer from the imported BO will fail and userspace will fall back to a copy.

drm/amd: print error on convert_tiling_flags_to_modifier failure

2020-12-09T04:02:24Z

If this function fails, it means the tiling flags didn't make sense. This likely indicates a user-space bug. Log the error alongside with the provided tiling flags to make debugging easier.

drm/amd: use drm_dbg_kms to log addfb2 failures

2020-12-09T04:02:21Z

Avoid printing an error with dev_err, because user-space can trigger these at will by issuing an ioctl. Convert a DRM_DEBUG_KMS call to the more modern drm_dbg_kms macro.

drm/amd/display: Extract 3rd plane from metadata

2020-11-13T22:29:47Z

Now that we actually expose the right number of planes we get problems with modifier aware libva if we use an unsupported modifier. So this ensures that we as much as possible use a modifier that radeonsi can actually render to without going to extreme difficulty to synchronize an extra DCC metadata plane with implicit sync. Looking into the opaque metadata isn't ideal but this converts to something mainly for the purpose of the userspace driver and falls back properly if it isn't what we expect.

drm/amd/display: Set new format info for converted metadata.

2020-11-13T22:29:47Z

If we use DCC modifiers this can increase the number of planes from the initial 1 plane with metadata, so that we get a valid modifier from getfb2. Since the code didn't update the format_info getfb2 would only ever return 1 plane with a modifier for which userspace expects > 1. This moves the format lookup to amdgpu_display.c so we do not have issues when DC is not compiled. Reviewed-by: Alex Deucher Signed-off-by: Bas Nieuwenhuizen Signed-off-by: Alex Deucher

drm/amd/display: Store gem objects for planes 1-3

2020-11-13T22:29:47Z

Also do the proper validation which was missed. Besides the missing validation, not storing the objects in the framebuffer led to wrong results in the getfb2 ioctl. Note that this should really have been done for multi-plane formats like NV12 already before modifiers landed. Reviewed-by: Alex Deucher Signed-off-by: Bas Nieuwenhuizen Signed-off-by: Alex Deucher
