[v3] vhost-user-gpu: fix import of DMABUF

[PATCH v3] vhost-user-gpu: fix import of DMABUF

Posted by marcandre.lureau@redhat.com 1 year, 9 months ago

From: Marc-André Lureau <marcandre.lureau@redhat.com>

When using vhost-user-gpu with GL, qemu -display gtk doesn't show output
and prints: qemu: eglCreateImageKHR failed

Since commit 9ac06df8b ("virtio-gpu-udmabuf: correct naming of
QemuDmaBuf size properties"), egl_dmabuf_import_texture() uses
backing_{width,height} for the texture dimension.

Fixes: commit 9ac06df8b ("virtio-gpu-udmabuf: correct naming of QemuDmaBuf size properties")
