Description Joan Torres 2023-06-08 08:36:40 UTC 
I'm trying to start a wlroots compositor (sway) on a QEMU machine is using the  Bochs DRM driver. (Kernel version 6.3.4-1-default).

The start fails saying PRIME import not supported.
I've seen there's already a patch that adds this:
https://lore.kernel.org/dri-devel/20230301222903.458692-1-contact@emersion.fr/T/#u

Could it be added to see if that fixes it?
How could I check if it was already added?

I asked upstream to move forward with that patchset.

The following commit are in v6.4-rc1 and later

41068c8b28e16 drm/vram-helper: turn on PRIME import/export
207395da5a970 drm/prime: reject DMA-BUF attach when get_sg_table is missing

The feature should be available in the upcoming v6.4 kernel.

Resolving this bug report as INVALID.

After considering Takashi's comment, I merged the two patches into stable. They should be in the next TW and ALP kernels.

Changing the status to RESOLVED/FIXED.
