Re: Porting DRM/GEM from OpenBSD


I re-synced the port with NetBSD HEAD.  Nothing else changed,
so the features and bugs remain the same.  I tested it briefly on
a Core i5 laptop.

Pre-built binaries (for amd64) are available at:

With respect to the previous pre-built binaries (from February),
the changes are:
- the xf86-video-intel driver includes display-port support.
- intel dri drivers are included, both and
  (the latter was mistakenly missing in the previous binaries).

Best regards,

I could make the Intel Xorg driver run on a Core i5 laptop, by

on this laptop is on an embedded display port (eDP), so I also
backported the Intel (e)DP driver from Linux to Xorg. The sources,
along with a README giving more details, are at:

I did not include display-port support by default in these
pre-built archives, to limit the number of bugs I introduced. ;-)
(Well, the amd64 archive has it, but it's hidden.)

The port is currently limited to Intel chipsets. I tested it
(a bit) on Ironlake (Core i5) and (a lot) on i915. If you give
it a try, I'd be happy to hear about it.

Warning: You may get gpu hangs that seem to be related to
timings (see
Returning to the console should still be possible, though.
As a workaround, enabling DebugWait in xorg.conf makes these
gpu hangs disappear for me.

There is still a lot of room for improvement (volunteers?),
but I hope that this is a step in the right direction to get
DRM/GEM(/KMS) support in NetBSD.

p.s. I'm mostly interested in basic desktop usage, so I didn't
look (much) into 3D, XvMC, etc.
