[linux-audio-user] [ANN] das_watchdog 0.1.2

Sorry for all the announcements. I think I got it right now. ;-) I have fixed up the compilation problems, corrected the DISPLAY environment variable, and let both the program and makefile give warning/error if the softirq-timer/0 or ksoftirqd/0 processes aren't set to have highest priority. It might still not work, but at least you get a message about /why/ it doesn't work, and what you can do to fix it. (Running "chrt -f -p 99 `ps -A |grep softirq-timer/0 |awk '{print $1}'`" for all processors (change the "0" in "softirq-timer/0" for each additional processor) is probably a good tip to make it work.) REQUIREMENTS ------------ xmessage (should be a part of X11) libgtop2 (should be a part gnome. No, das_watchdog is not a gnome-program.) CHANGES ------- 0.1.0->0.1.2 * Added check for the ksoftrqd/0 process as well as the softirq-timer/0 process. * Added check for SCHED_OTHER of the timing process as well as priority. * Removed debug-printing. * Added extensive checks both when compiling and when running about the priority of the "softirq-timer/0" process: - ***If "softirq-timer/0" is not set to a very high priority (99), the watchdog most probably will not work.*** - The default priority for softirq-timer/0 seems to be 1. However, for real time work, it must be set higher to get reliable timing. Set it to 99. - If softirq-timer/0 is set to less than 99, das_watchdog will refuse to compile unless you force it to by editing the makefile. When running das_watchdog, it will only give a warning if the priority is set too low. * Changed the DISPLAY environment variable to ":0.0" instead of "localhost:0.0". Seems to work for everyone now. * Switched from libgtop to libgtop2. Download from http://ccrma.stanford.edu/~kjetil/src/
