The current gem prime helpers handle this reasonable well,
I don't see a need for that.
More useful would be some way to signal this self-reimport capability
to userspace somehow. See DRM_PRIME_CAP_LOCAL patch.
Right now I have the choice to set DRM_PRIME_CAP_{IMPORT,EXPORT}, in
which case some userspace assumes it can do cross-driver export/import
and trips over that not working. Or I do not set
DRM_PRIME_CAP_{IMPORT,EXPORT}, which breaks DRI3 ...

Userspace is supposed to test whether import/export works for a
specific combo, not blindly assume it does and then keel over. I think
we need to fix that, not add more flags - there's lots of reasons why
a given pair of devices can't share buffers (e.g. all the contiguous

[PATCH] Revert "drm/qxl: drop prime import/export callbacks"
This reverts commit f4c34b1e2a37d5676180901fa6ff188bcb6371f8.
Simliar to commit a0cecc23cfcb Revert "drm/virtio: drop prime
import/export callbacks". We have to do the same with qxl,
for the same reasons (it breaks DRI3).
Drop the WARN_ON_ONCE().
Fixes: f4c34b1e2a37d5676180901fa6ff188bcb6371f8
