1. Please do not add the amdgpu_sriov_vf check in every psp fw init_microcode function. psp_init_microcode is the entry point for all kinds of psp fw microcode initialization.
2. I'd like to get a whole picture on all the sequence you want to skip from guest side so that we can have more organized/reasonable approach to exclude those programing sequence for SRIOV, instead of having the amdgpu_sriov_vf patched case by case...
Regards,
Hawking

Subject: [PATCH 2/2] drm/amd: Skip not used microcode loading in SRIOV
smc, sdma, sos, ta and asd fw is not used in SRIOV. Skip them to accelerate sw_init for navi12.
v2: skip above fw in SRIOV for vega10 and sienna_cichlid
