- Yet more steps towards atomic modeset from Ville. - DP panel power sequencing improvements from Paulo. - irq code cleanups from Ville. - 5.4 GHz dp lane clock support for bdw/hsw from Todd. - Clock readout support for hsw/bdw (aka fastboot) from Jesse. - Make pipe underruns report at ERROR level (Ville). This is to check our improved watermarks code. - Full ppgtt support from Ben for gen7. - More fbc fixes and improvements from Ville all over the place, unfortunately not yet enabled by default on more platforms. - w/a cleanups from Ville. - HiZ stall optimization settings (Chia-I Wu). - Display register mmio offset refactor patch from Antti. - RPS improvements for corner-cases from Jeff McGee. * tag 'drm-intel-next-2014-02-07' of ssh://git.freedesktop.org/git/drm-intel: (166 commits) drm/i915: Update rps interrupt limits drm/i915: Restore rps/rc6 on reset drm/i915: Prevent recursion by retiring requests when the ring is full drm/i915: Generate a hang error code drm/i915: unify FLIP_DONE macro names drm/i915: vlv: s/spin_lock_irqsave/spin_lock/ in irq handler drm/i915: factor out valleyview_pipestat_irq_handler drm/i915: vlv: don't unmask IIR[DISPLAY_PIPE_A/B_VBLANK] interrupt drm/i915: Reorganize display pipe register accesses drm/i915: Treat using a purged buffer as a source of EFAULT drm/i915: Convert EFAULT into a silent SIGBUS drm/i915: release mutex in i915_gem_init()'s error path drm/i915: check for oom when allocating private_default_ctx drm/i915/vlv: WA to fix Voltage not getting dropped to Vmin when Gfx is power gated. drm/i915: Get rid of acthd based guilty batch search drm/i915: Use hangcheck score to find guilty context drm/i915: Drop WaDisablePSDDualDispatchEnable:ivb for IVB GT2 drm/i915: Fix IVB GT2 WaDisableDopClockGating and WaDisablePSDDualDispatchEnable drm/i915: Don't access snooped pages through the GTT (even for error capture) drm/i915: Only print information for filing bug reports once ...

************************************************************
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://dri.freedesktop.org/wiki/Documentation
http://sourceforge.net/project/showfiles.php?group_id=387
http://dri.sourceforge.net/doc/
