https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D266315 --- Comment #58 from Paul Dufresne <dufresnep@zoho.com> --- (In reply to jakub_lach from comment #55) man intel (on FreeBSD) shows that UXA is default, and I can confirm that fr= om Xorg.0.log: [ 52.583] (II) Module "dri2" already built-in [ 52.583] (II) intel(0): Allocated new frame buffer 1280x1024 stride 512= 0, tiled [ 52.606] (II) UXA(0): Driver registered support for the following operations: [ 52.606] (II) solid [ 52.606] (II) copy [ 52.606] (II) put_image [ 52.606] (II) get_image [ 52.606] (II) intel(0): [DRI2] Setup complete [ 52.606] (II) intel(0): [DRI2] DRI driver: iris [ 52.606] (II) intel(0): [DRI2] VDPAU driver: va_gl But on Ubuntu: https://manpages.ubuntu.com/manpages/xenial/man4/intel.4.html default is sna, apparently There is also "AccelMethod" "blt": (limited UXA) or "blt" to disable render acceleration and only use the BLT engine I found info on BLT engine in section 3.2.2.2 of: https://www.intel.ca/content/dam/doc/datasheet/atom-d2000-n2000-vol-1-datas= heet.pdf You might want to check: Option "RelaxedFencing" "boolean" This option controls whether we attempt to allocate the minim= al amount of memory required for the buffers. The reduction in working set has a substantial improvement on system performan= ce. However, this has been demonstrate to be buggy on older hardw= are (845-865 and 915-945, but ok on PineView and later) so on tho= se chipsets defaults to off. Default: Enabled for G33 (includes PineView), and later, class machines. Should be decided by your GPU, but might make sure. --=20 You are receiving this mail because: You are the assignee for the bug.=
