Revert "drm/virtio: drop prime import/export callbacks"
This patch does more harm than good, as it breaks both Xwayland and gnome-shell with X11. Xwayland requires DRI3 & DRI3 requires PRIME. X11 crash for obscure double-free reason which are hard to debug (starting X11 by hand doesn't trigger the crash). I don't see an apparent problem implementing those stub prime functions, they may return an error at run-time, and it seems to be handled fine by GNOME at least. This reverts commit b318e3ff7ca065d6b107e424c85a63d7a6798a69. [airlied: This broke userspace for virtio-gpus, and regressed things from DRI3 to DRI2. This brings back the original problem, but it's better than regressions.] Fixes: b318e3ff7ca065d6b107e424c85a63d7a6798a ("drm/virtio: drop prime import/export callbacks") Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
