  • IVB FDI B/C fixes

  • HSW sprite/plane offset fixes

  • Unified DP/HDMI encoder for HSW

  • DP support on HSW

  • HSW VGA fixes

  • VLV DP support

  • Panel fitter scaling modes

  • Panel power improvements

  • Secure batchbuffer support

2D driver


  • Enable render acceleration for Haswell GT1/GT2

  • Prevent 16-bit overflow

  • Disable RandR hotplug events if Xinerama is enabled

  • Prevent use of invalid damage pointers when redirecting rendering

  • Fix the gen4/5 opacity shader

  • Improve handing of texture fallbacks for 830/845

  • Tune batch flushing after an operation to an exported surface under a compositor.

  • Immediately flush in the block handler after a split batch to reduce latency between the two halves of an operation.

  • Install a fallback config if we fail to install the desired config at VT switch - (IVB 3 pipes fix)

  • Pin batches to avoid CS incoherence on 830/845

  • Implement the GNOME Build API.

  • Explicity prevent ring-switching for synchronized rendering to scanouts (for vsync)

  • Clip dirty region to slave pixmaps

  • Enable multi-threaded rasterization of trapezoids and fallback composition

  • PRIME support for hotplug GPUs and hybrid systems

  • Support for IvyBridge GT1 machines, aka HD2500 graphics

  • Stable 830gm/845g support

  • Make driver more robust against its own failures to submit batches

  • Fix the UXA render programs for projective transforms on Ivybridge

Known issues

There are important known fixed bugs and performance improvements coming on newest individual components releases that weren't included in this stack release.

  • Mesa - 9.1.1 contains important fixes and performance improvements compared to 9.1 validated in this stack
  • xf86-video-intel 2.21.5 contains important fixes for HSW like "Fix scanline waits for Haswell" and "Fix Haswell CRW PCI-IDs"

All these fixes and improvements will be included and validated only on next stack release 2013Q2.
