This realised itself in impossible performance figures and + the entire display freezing for several seconds whlist the GPU caught + up. One side effect is that it also caused the DDX to consume more + memory than was required as it could not recycle buffers quick + enough, and in some cases this produces a marked improvement in + performance. Also note on gen2/3 this requires a new libdrm [2.4.41] + in order to prevent a bug causing the DDX to fallback to swrast. + Release 2.20.17 (2012-12-26) ============================ A minor update to prepare for co-operating with the kernel over managing |
