As an added bonus, the pessimistic workaround for a +GPU hang on gen4 has been relaxed and the shaders have been overhauled +which should pave the way to eliminating the last of the uncommon CPU +operations, along with immediately realising a small perforamnce +improvement. + +Bugs fixed since 2.20.2: + + * Update DPMS bookkeeping after modeset + https://bugs.freedesktop.org/show_bug.cgi?id=52142 + + * Avoid overlapping gpu/cpu damage after ignoring cpu damage in the + consideration of placement for the operation. + + * Enable acceleration by default on 830gm/845g. The GMCH on this pair + of chipsets is notoriously incoherent, so the GPU is almost certainly + going to hang at some point, though unlikely to hang the system and + should automatically disable acceleration (and thence behave + identically as if the acceleration was disabled from the start). + Option "NoAccel" can be used to disable all 2D acceleration and + Option "DRI" can be used to disable all 3D acceleration. + https://bugs.freedesktop.org/show_bug.cgi?id=52624 + + * Fix vertex bookkeeping for gen4 that was causing corruption in the + command stream. + Release 2.20.2 (2012-07-27) =========================== For the last 9 months, since 2.16.901, we have been shipping a driver that |
