Author: Rob Clark <[email protected]> Date: Thu May 12 08:04:56 2022 -0700 freedreno/drm/virtio: Don't try to mmap imported bo's Previously it would fail, and then we'd fall back to the transfer path for things like readpix. But it would spam logcat w/ bo_mmap fail messages. Since gralloc allocated buffers for GPU usage are allocate without _USE_MAPPABLE, let's just assume we can't map imported bo's.
