From 057f91645cef412fe460b17fa50726c8a1c5921c Mon Sep 17 00:00:00 2001 From: Yintian Tao Date: Thu, 16 May 2019 13:07:26 +0800 Subject: [PATCH] drm/amdgpu: skip fw pri bo alloc for SRIOV MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 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().
