Introduce tile members for future tiled buffer support.
Allow user-space to explicitly define a fence-class.
Remove the implicit fence-class mechanism.
64-bit wide buffer object flag member.
This just cleans up the xf86drm.c to what I want and drm.h,
I need to fix up the kernel internals to suit these changes now.
I've moved to using struct instead of typedefs for the bo and it doesn't look
that bad so I'll do the same thing for mm and fence..
This adds the user interfaces from Jakob and hooks them up for 3 ioctls
GetResources, GetCrtc and GetOutput.
I've made the ids for everything fbs, crtcs, outputs and modes go via idr as
per krh's suggestion on irc as it make the code nice and consistent.
This will come in very handy for tiled buffers on intel hardware.
Also add some padding to interface structures to allow future binary backwards
compatible changes.
The mm_lock function is used when leaving vt. It evicts _all_ buffers.
Buffers with the DRM_BO_NO_MOVE attribute set will be guaranteed to
get the same offset when / if they are rebound.
Adapt for new functions in the 2.6.19 kernel.
Remove the ability to have multiple regions in one TTM.
This simplifies a lot of code.
Remove the ability to access TTMs from user space.
We don't need it anymore without ttm regions.
Don't change caching policy for evicted buffers. Instead change it only
when the buffer is accessed by the CPU (on the first page fault).
This tremendously speeds up eviction rates.
Current code is safe for kernels <= 2.6.14.
Should also be OK with 2.6.19 and above.
When this flag is set and the target sequence is missed, wait for the next
vertical blank instead of returning immediately.
(cherry picked from 89e323e490 commit)
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.

Change the fence object interface somewhat to allow some more flexibility.
Make list IOCTLS really restartable.
Try to avoid busy-waits in the kernel using immediate return to user-space with an -EAGAIN.
- 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🅱ï¸d:f format.
- Use the new DRICreatePCIBusID function in the *_dri.c to request the new,
more exact busid format.
glide header files.
The changes include:
- Brian Paul's changes to the tdfx client-side 3D driver to make it
dlopen() the correct glide library (Voodoo3 or Voodoo5). This allows
both types of the glide library to co-exist, and allows Voodoo3/Voodoo5
cards to be mixed in multi-head configs.
- DRM kernel driver changes to allow a driver to set up multiple instances
(minor numbers), one for each card present that the driver supports.
This is currently implemented and tested only for the tdfx DRM driver.
- Add some missing missing <stdarg.h> includes.
- Some log message cleanups.
- Change the 2D tdfx driver to access VGA legacy registers via their PCI
I/O space access points rather than their legacy addresses, and fix
some problems with the way the VGA-related bits are initialised.
Status:
- With these changes, multi-head direct rendering works with multiple
Voodoo3 and/or Voodoo5 cards. This has been tested with two PCI Voodoo3
cards and an AGP Voodoo5 card, and all permutations of those.
Caveats:
- Xinerama is not supported. If Xinerama is enabled, then direct rendering
gets disabled.
- The text mode on secondary screens will show junk after the X server
exits.
- On some hardware, starting the X server on multiple 3dfx cards will
result in a hard lockup. One workaround is to enable APIC support in a
uni-processor kernel, or use an SMP kernel.
more flexible and allow older module versions to still work. Might not
be final code if we move over to DRI kernel module version, but will be
if we use XFree86 version. + Only build tdfx.o instead of tdfx-4_1_0.o
since tdfx.o has never changed its API.
