I have some follow-up cleanups pending, already acked by Andrew Morton. - Some prep-work for the crazy no-pch/display-less platform by Ben. - Some vlv patches, by far not all (Jesse et al). - Clean up the HDMI/SDVO #define confusion (Paulo) - gen2-4 vblank fixes from Ville. - Unclaimed register warning fixes for hsw (Paulo). More still to come ... - Complete pageflips which have been stuck in a gpu hang, should prevent stuck gl compositors (Ville). - pm patches for vt-switchless resume (Jesse). Note that the i915 enabling is not (yet) included, that took a bit longer to settle. PM patches are acked by Rafael Wysocki. - Minor fixlets all over from various people. * tag 'drm-intel-next-2013-03-23' of git://people.freedesktop.org/~danvet/drm-intel: (79 commits) drm/i915: Implement WaSwitchSolVfFArbitrationPriority drm/i915: Set the VIC in AVI infoframe for SDVO drm/i915: Kill a strange comment about DPMS functions drm/i915: Correct sandybrige overclocking drm/i915: Introduce GEN7_FEATURES for device info drm/i915: Move num_pipes to intel info drm/i915: fixup pd vs pt confusion in gen6 ppgtt code style nit: Align function parameter continuation properly. drm/i915: VLV doesn't have HDMI on port C drm/i915: DSPFW and BLC regs are in the display offset range drm/i915: set conservative clock gating values on VLV v2 drm/i915: fix WaDisablePSDDualDispatchEnable on VLV v2 drm/i915: add more VLV IDs drm/i915: use VLV DIP routines on VLV v2 drm/i915: add media well to VLV force wake routines v2 drm/i915: don't use plane pipe select on VLV drm: modify pages_to_sg prime helper to create optimized SG table drm/i915: use for_each_sg_page for setting up the gtt ptes drm/i915: create compact dma scatter lists for gem objects drm/i915: handle walking compact dma scatter lists ...

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:
