Yes, that's what I meant. glxgears runs in 300x300 pixels or something like that. > Does setting the RADEON_NO_USLEEPS and/or RADEON_NO_IRQS environment > variable(s) make a difference? (See > http://dri.sourceforge.net/doc/dri_driver_features.phtml for a list of > other environment variable to tweak driver behaviour) NO_IRQS drops the framerate down to ~ 100 fps. NO_USLEEPs doesn't change anything noticable. NO_VTXFMT neither. NO_CODEGEN neither. LIBGL_PERFORMANCE_BOXES doesn't do anything. TCL_FORCE_[DIS|EN]ABLE neither (I doubt that glxgears uses it) COMPAT makes glxgears fail an assert in radeon_ioctl.h AGP and MTRR are enabled. $ cat /proc/mtrr reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1 reg01: base=0xc0000000 (3072MB), size= 64MB: write-combining, count=2 reg02: base=0xd0000000 (3328MB), size= 64MB: write-combining, count=1 $ seems sound, does it? If it is rather a DRI bug than a packaging related flaw I can carry it over to dri-devel. What do you think? Cheers, Moritz
