file derived from msm-next kernel uapi header.


Unless there's an exception from Dave, I believe uapi headers in libdrm and Mesa should be direct copies from "make headers_install" on the
drm-next branch.  How does this compare to that?


The header file is identical as in drm-next kernel.


Great, let's say "drm-next" instead to make that clear.  Also, looks
like freedreno/msm/msm_drm.h should probably get removed in favor of
this?

Thanks Eric, I will send v2 with suggested changes.

freedreno/msm/msm_drm.h is owned by Rob, I am not sure if we need it there
or not. I would let Rob comment on this.

We require msm_drm.h in include/drm/ directory to export GEM ioctls so
other modules
such as gbm can use it. Other platforms have similar strategy.


Sorry, Actually +Rob Clark

yeah, we should remove the duplicate header in libdrm.. so far it
hasn't been exported outside of libdrm_freedreno since it was
unneeded.. but as long as libdrm_freedreno still compiles properly
with the moved header, I'm fine with it.  There might be some include
path tweaking required, not sure..

(and PS. "ownership" is not a thing upstream.. if it lives in the same
git tree and changing it doesn't break the build, it is not off-limits
;-))

BR,
-R

Thanks, Rob.
