This will allow Mesa to port code to Windows more easily.
As discussed in
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6162#note_712779
, including drm.h makes no sense when building for Windows.
Yeah I think it'd be cleanest if we can avoid this. If not I think the
right fix would be to split out the actually needed parts from drm.h
into a new header (still included by drm.h for backwards compat
reasons) which mesa can use. Since it looks like the problematic parts
are the legacy gunk, and not the new ioctl structures. Pulling out
drm_render.h for all the render stuff and mabe drm_vblank.h for the
vblank stuff (which would fit better in drm_mode.h but mistakes were
made, oops).
If anything currently in drm.h is needed while building for Windows, it
points to a broken abstraction somewhere in userspace. (Specifically,
the Mesa Gallium/Vulkan winsys is supposed to abstract away platform
details like these)
