drm/amdgpu: load sdma ucode in the guest machine

2023-07-25T17:47:26+00:00

[why] User mode driver need to check the sdma ucode version to see whether the sdma engine supports a new type of PM4 packet. In SRIOV, sdma is loaded by the host. And, there is no way to check the sdma ucode version of CHIP_NAVI12 and CHIP_SIENNA_CICHLID of the host in the guest machine. [how] Load the sdma ucode for CHIP_NAVI12 and CHIP_SIENNA_CICHLID in the guest machine. Signed-off-by: YuanShang Reviewed-By: Horace Chen Signed-off-by: Alex Deucher

drm/amd: Make SDMA firmware load failures less noisy.

2023-01-09T22:02:17+00:00

When firmware is missing we get failures at every step. ``` [ 3.855086] amdgpu 0000:04:00.0: Direct firmware load for amdgpu/green_sardine_sdma.bin failed with error -2 [ 3.855087] [drm:amdgpu_sdma_init_microcode [amdgpu]] *ERROR* SDMA: Failed to init firmware "amdgpu/green_sardine_sdma.bin" [ 3.855398] [drm:sdma_v4_0_early_init [amdgpu]] *ERROR* Failed to load sdma firmware! ``` Realistically we don't need all of these, a user can tell from the first one that request_firmware emitted what happened.

drm/amdgpu/sdma: add missing release_firmware() in amdgpu_sdma_init_microcode()

In some error path in amdgpu_sdma_init_microcode(), release_firmware() is not called, the memory allocated in request_firmware() will be leaked, calling amdgpu_sdma_destroy_inst_ctx() which calls release_firmware() to avoid memory leak.
