Hi,
The current post-loading code for scanout has a FIXME: it doesn't take the
resource region/rect into account. But there is more, when adding blob migration
support in commit f66767f75c9, I didn't realize that blob resources could be
used for scanouts. This situationn leads to a crash during post-load, as they
don't have an associated res->image.
virtio_gpu_do_set_scanout() handle all cases, but requires the associated
virtio_gpu_framebuffer, which is currently not saved during migration.
Add a v2 of "virtio-gpu-one-scanout" with the framebuffer fields, so we can
restore blob scanouts, as well as fixing the existing FIXME.
v2:
- modify first patch to get rid of another needless check (Sebastian Ott)
Marc-André Lureau (2):
virtio-gpu: remove needless condition
virtio-gpu: fix scanout migration post-load
