Subject: [PATCH 1989/2940] drm/amdgpu: skip fw pri bo alloc for SRIOV
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
PSP fw primary buffer is not used under SRIOV.
Under SRIOV, VBIOS or hypervisor driver will load psp
sos and psp sysdrv. Therefore, we don't need to
allocate memory for it.
v2: remove superfluous check for amdgpu_bo_free_kernel().
