2021-09-28drm/amdgpu: check tiling flags when creating FB on GFX8-Simon Ser
On GFX9+, format modifiers are always enabled and ensure the frame-buffers can be scanned out at ADDFB2 time. On GFX8-, format modifiers are not supported and no other check is performed. This means ADDFB2 IOCTLs will succeed even if the tiling isn't supported for scan-out, and will result in garbage displayed on screen [1]. Fix this by adding a check for tiling flags for GFX8 and older. The check is taken from radeonsi in Mesa (see how is_displayable is populated in gfx6_compute_surface).

2021-09-23drm/amd/pm: Update intermediate power state for SILijo Lazar
Update the current state as boot state during dpm initialization. During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

2021-09-14amd/display: downgrade validation failure log levelSimon Ser
In amdgpu_dm_atomic_check, dc_validate_global_state is called. On failure this logs a warning to the kernel journal. However warnings shouldn't be used for atomic test-only commit failures: user-space might be perfoming a lot of atomic test-only commits to find the best hardware configuration. Downgrade the log to a regular DRM atomic message. While at it, use the new device-aware logging infrastructure. This fixes error messages in the kernel when running gamescope [1].
