* drm/amd: Add the capability to mark certain firmware as "required"Mario Limonciello2024-12-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | Some of the firmware that is loaded by amdgpu is not actually required. For example the ISP firmware on some SoCs is optional, and if it's not present the ISP IP block just won't be initialized. The firmware loader core however will show a warning when this happens like this: ``` Direct firmware load for amdgpu/isp_4_1_0.bin failed with error -2 ``` To avoid confusion for non-required firmware, adjust the amd-ucode helper to take an extra argument indicating if the firmware is required or optional. On optional firmware use firmware_request_nowarn() instead of request_firmware() to avoid the warnings.

* drm/amdgpu: recover gart table at resumeNirmoy Das2022-01-111-2/+1
| | | | | | | | | | | | | | | Get rid off pin/unpin of gart BO at resume/suspend and instead pin only once and try to recover gart content at resume time. This is much more stable in case there is OOM situation at 2nd call to amdgpu_device_evict_resources() while evicting GART table. v3: remove gart recovery from other places v2: pin gart at amdgpu_gart_table_vram_alloc() Reviewed-by: Christian König <[email protected]> Signed-off-by: Nirmoy Das <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
