Besides these regression fixes, there +are a couple of fixes for some long standing issues, such as incorrect +rendering on gen2, an infinite loop with very, very large pixmaps and a +slight improvement to the tempermental gen4. + + * Allow untiled scanouts again (required for large extended desktops on + gen2 and gen3). + [Regression from 2.21.11] + + * Use the correct count of the number of dirty damage boxes for the quick + check on whether the existing damage contains the requested area. + The danger is that we may get a false result and skip migration and so + cause pixmap corruption (in the unlikely event that the application + frequently causes fallbacks). + [Regression from 2.21.11] + https://bugs.freedesktop.org/show_bug.cgi?id=66430 + + * Fix initial connection probing for multi-function encoders, such as the + external connections on Haswell. + [Regression from 2.21.11, initial connection probing] + https://bugs.freedesktop.org/show_bug.cgi?id=66488 + + * Fix gen2 rendercopy into a8 surfaces, for example, glyph uploads into + the glyph cache. + + * Fix detection of user overrides for initial connection configuration. + The code used the xorg-server-1.15 values, having missed the + introduction of ZoomModes into that release. + [Regression from 2.21.11, initial connection probing] + + * Always initialise the gamma ramp, even on unconnected CRTCs. + https://bugs.freedesktop.org/show_bug.cgi?id=66563 + [Regression from 2.21.11, initial connection probing] + + * Some more tuning of the gen4 vertex corruption workaround. The root + cause behind the GPU using incorrect texture coordinates is still + not solved, but by reducing the maximum number or rectangles in + flight through the GPU we reduce the likelihood of corruption. + + * Fix compilation with gcc-4.5 + [Regression from 2.21.11] + + * Avoid integer overflow when performing tiled uploads and operations + on very large (>28k pixels wide or tall pixmaps) + https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1200766 + + Release 2.21.11 (2013-06-30) ============================ An eventful week.
