* 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (21 commits) Fix http://bugzilla.kernel.org/show_bug.cgi?id=7606 drm: add flag for mapping PCI DMA buffers read-only. drm: fix up irqflags in drm_lock.c drm: i915 updates drm: i915: fix up irqflags arg drm: i915: Only return EBUSY after we've established we need to schedule a new swap. drm: i915: Fix 'sequence has passed' condition in i915_vblank_swap(). drm: i915: Add SAREA fileds for determining which pipe to sync window buffer swaps to. drm: Make handling of dev_priv->vblank_pipe more robust. drm: DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead drm: i915: Add ioctl for scheduling buffer swaps at vertical blanks. drm: Core vsync: Don't clobber target sequence number when scheduling signal. drm: Core vsync: Add flag DRM_VBLANK_NEXTONMISS. drm: Make locked tasklet handling more robust. drm: drm_rmdraw: Declare id and idx as signed so testing for < 0 works as intended. drm: Change first valid DRM drawable ID to be 1 instead of 0. drm: drawable locking + memory management fixes + copyright drm: Add support for interrupt triggered driver callback with lock held to DRM core. drm: Add support for tracking drawable information to core drm: add support for secondary vertical blank interrupt to i915 ... |

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).
The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:
1. The DRM provides synchronized access to the graphics hardware via
the use of an optimized two-tiered lock.
2. The DRM enforces the DRI security policy for access to the graphics
hardware by only allowing authenticated X11 clients access to
restricted regions of memory.
3. The DRM provides a generic DMA engine, complete with multiple
queues and the ability to detect the need for an OpenGL context
switch.
4. The DRM is extensible via the use of small device-specific modules
that rely extensively on the API exported by the DRM module.
Documentation on the DRI is available from:
http://precisioninsight.com/piinsights.html
