What's New:

New features

• Enable render acceleration for Haswell GT1/GT2.
• Enable multi-threaded rasterisation of trapezoids and fallback composition
• Utilile a new kernel interface (v3.9) for processing relocations

Older features from the 2.20.x series:

• PRIME support for hotplug GPUs and hybrid systems
• Support for IvyBridge GT1 machines, aka HD2500 graphics.
• Stable 830gm/845g support, at last!

Bug Fixes:

• Prevent a stray relocation being left after a buffer is removed from a batch, leading to GPU hangs.
• Make the driver more robust against its own failures to submit batches by falling back to software rendering.
• Fix emission of scanline waits for secondary pipes on gen6/7. Otherwise you may encounter GPU hangs in MI_WAIT_FOR_EVENT.
• Fix a missing corner pixel when drawing rectangles PolyLines https://bugs.freedesktop.org/show_bug.cgi?id=55484
• Don't try to use Y-tiling colour buffers mesa/i915c as mesa doesn't support them and wil fallback to software rendering
• Ensure that any cached mmaps are invalidated for a SwapBuffers https://bugs.freedesktop.org/show_bug.cgi?id=60042
• Correctly handle the composition of rotated displays too large for the 3D pipeline https://bugs.freedesktop.org/show_bug.cgi?id=60124
• Fix the computation of the planar video frame size https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104180
