Actually make the existing ioctls for adding and removing drawables do
something useful, and add another ioctl for the X server to update drawable
information. The only kind of drawable information tracked so far is cliprects.
- Add $(DESTDIR) for distributors doing package creation
- Remove OS-specific include path from build
- Add /usr/include/drm for driver-kernel API
- Install all of shared-core/*.h in /usr/include/drm
- Rename xf86drm.h to libdrm.h since we're not X biased anymore
- Include backwards compat for xf86drm.h name, with a warning
- Fix libdrm source to account for drm.h living in /usr/include/drm
- create libdrm.so target
- build it by default
- drop xf86drmCompat.c from the build
- make 'clean' target never fail
- use pattern rules for .c -> .o for parallelism
- add 'install' target
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP
memory but uses video memory.

xc/xc/programs/Xserver/hw/xfree86/os-support/linux/drm/xf86drm.c so
that it matches the prototypes in xf86drm.h XFree86 bug: Reported by:
Submitted by: Reviewed by: Obtained from:
server or client to notify the DRM that it expects a certain version of
the device dependent or device independent interface. If the major
doesn't match or minor is too large, EINVAL is returned. A major of -1
means that the requestor doesn't care about that portion of the
interface. The ioctl returns the actual versions in the same struct.
- Introduce DRM DI interface version 1.1. If the server requests version
1.1, then the DRM sets the unique itself according to the busid of the
device it probed, which may then be accessed as normal using getunique.
- Request version 1.1 in libdrm's drmOpenByBusID, allowing the X Server to
request based on a BusID. Introduce a wrapper for DRM_IOCTL_SET_VERSION
and bump libdrm minor version.
- Pass the busid in DRIScreenInit if libdrm can handle both a busid and
name. This allows drmOpenByBusID to be used to find the DRM instead of
just the driver name, which allows us in the future to tie a DRM more
strongly to the device it probed to. Introduce a function
DRICreatePCIBusID which creates a busid in the form pci:oooo:bb:dd.f
similar to linux's pci_name() function. This matches the format used by
the DRM in version 1.1. libdrm knows how to match both this format and
the old PCI🅱️d:f format.
- Use the new DRICreatePCIBusID function in the *_dri.c to request the new,
more exact busid format.
