* drm/amdgpu: Add a noverbose flag to psp_wait_forLijo Lazar2025-07-071-20/+21

* drm/amd: Load PSP microcode during early_initMario Limonciello2023-01-101-12/+4
| | | | | | | | | | | | | | Simplifies the code so that all PSP versions will get the firmware name from `amdgpu_ucode_ip_version_decode` and then use this filename to load microcode as part of the early_init process. Any failures will cause the driver to fail to probe before the firmware framebuffer has been removed.

* drm/amdgpu: Add interface to load SRIOV cap FWBokun Zhang2022-01-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | - Add interface to load SRIOV cap FW. If the FW does not exist, simply skip this FW loading routine. This FW will only be loaded under SRIOV. Other driver configuration will not be affected. By adding this interface, it will make us easier to prepare SRIOV Linux guest driver for different users. - Update sysfs interface to read cap FW version. - Refactor PSP FW loading routine under SRIOV to use a unified SWITCH statement instead of using IF statement - Remove redundant amdgpu_sriov_vf() check in FW loading routine Acked-by: Monk Liu <[email protected]> Acked-by: Guchun Chen <[email protected]> Signed-off-by: Bokun Zhang <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
