drm/amdgpu: postpone entering fullaccess mode (2f294132) · Commits · 戴 / test

if host support new handshake we only need to enter fullaccess_mode in ip_init() part, otherwise we need to do it before reading vbios (becuase host prepares vbios for VF only after received REQ_GPU_INIT event under legacy handshake) Signed-off-by:
