In RTLinux "wierd X" delays are only caused by hardware bus locks and there is no framebuffer problem. The scheduler test shows hardware problems. In any case, who cares? Latencies are latencies. The good thing about the RTLinux scheduler and timer tests are that they show delays that application code will actually experience. If your robot tosses a 300Kilo steel bar through the wall, a "buslock" test that didn't account for such things as a stupid hardware design where video memory was put in main memory won't do you much good. -- --------------------------------------------------------- Victor Yodaiken Finite State Machine Labs: The RTLinux Company. www.fsmlabs.com www.rtlinux.com -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/
