2007-07-18drm: remove drm_u64_t, replace with uint64_t everwhereDave Airlie
This might break something, stdint.h inclusion in drm.h maybe required but I'm not sure yet what platforms have it what ones don't.
2007-04-26libdrm: remove HAVE_XORG_CONFIG_H and XFree86LOADER ifdef's.George Sapountzis
We no longer import libdrm in the xserver.
2007-02-22Add DRM_VBLANK_FLIP.Michel Dänzer
Used to request that a scheduled buffer swap be done as a flip instead of a blit.
2006-11-09libdrm: add drmOpenOnce + drmCloseOnce to libdrmDave Airlie
2006-11-08libdrm: add support for server side functionality in libdrmDave Airlie
This adds APIs to allow the X server to use libdrm from the system rather than its own in-built copy.

2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #3.George Sapountzis
Add DRM_PCI_BUFFER_RO flag for mapping PCI DMA buffer read-only. An additional flag is needed, since PCI DMA buffers do not have an associated map.
2006-09-29Core vsync: Add flag DRM_VBLANK_NEXTONMISS.Michel Dänzer
When this flag is set and the target sequence is missed, wait for the next vertical blank instead of returning immediately. (cherry picked from 89e323e4900af84cc33219ad24eb0b435a039d23 commit)
2006-09-29Add definition of DRM_VBLANK_SECONDARY.Michel Dänzer
(cherry picked from 84b38b63f05e04ade8b1ddfb770047fd86de0d64 commit)
2006-09-29Add support for tracking drawable information to coreMichel Dänzer
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. (cherry picked from 29598e5253ff5c085ccf63580fd24b84db848424 commit)

2006-09-15Some bugfixes.Thomas Hellstrom
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.
2006-09-12More bugfixes.Thomas Hellstrom
Disable the i915 IRQ turnoff for now since it seems to be causing problems.
2006-09-05Fence all unfenced buffers function.Thomas Hellstrom
2006-08-30Memory manager init and takedown.Thomas Hellstrom
2006-08-29Part of buffer object libdrm interface.Thomas Hellstrom
2006-08-28Add a 64-bit drm unsigned type for 64-bit clean IOCTLS.Thomas Hellstrom
Conversion functions in drmP.h and xf86drm.c.
2006-08-27Bugfixes.Thomas Hellstrom
2006-08-27Remove the ioctl multiplexing, and instead allow for genericThomas Hellstrom
drm ioctls 0x80 - 0xFF.
2006-08-22Add a fence object class field for future use (For example VSYNC fence objects)Thomas Hellstrom
2006-08-21User / Kernel space fence objects (device-independent part).Thomas Hellstrom
2006-02-20Formatting cleanup, dead code removal. Remove N() namespacing macro,Adam Jackson
useless. Remove SIGIO handling functions as they're server-only and properly belong in libdri.
2005-11-29fixes from Egbert for 64bitDave Airlie
2005-10-22Bug #328: Silence read-from-uninitialized warnings in DRM_CAS on Alpha.Adam Jackson
(David Dawes)
2005-08-23add options for x86_64 and amd will small lettersDave Airlie
2005-02-01momentary revert. libdrm build may be broken now, but no one uses it yet...Adam Jackson
2005-01-30Final pass of libdrm.so work:Adam Jackson
- 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
2005-01-16The patch makes drmAddBufs/drmMapBufs can handle buffers in video memoryDave Airlie
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP memory but uses video memory. From: austinyuan@viatech.com.cn (fd.o bug 1668) Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-01-01Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It usesFelix Kuehling
drm_pci_alloc/free for allocating/freeing the memory. Only implemented in the Linux DRM so far.
2004-07-31Patch picked up from Redhat xorg release:Dave Airlie
Patch by John Dennis <jdennis@redhat.com> which fixes DRI locking bug on ia64 architecture. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=104338 http://bugs.xfree86.org/show_bug.cgi?id=778
