Kevin, I loaded qsynth & qjackctrl on my Mandriva 2008.0 disk, but every time I attempt to start the jack daemon using qjackctrl I get... 16:25:03.989 Startup script terminated with exit status=32512. 16:25:03.990 JACK is starting... 16:25:03.990 /usr/bin/jackd -R -dalsa -dhw:0 -r48000 -p1024 -n2 jackd 0.107.2 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. cannot use real-time scheduling (FIFO at priority 10) [for thread -1210526016, from thread -1210526016] (1: Operation not permitted) cannot create engine 16:25:04.003 JACK was started with PID=24050. 16:25:04.037 JACK was stopped successfully. 16:25:04.038 Post-shutdown script... 16:25:04.038 killall jackd jackd: no process killed 16:25:04.446 Post-shutdown script terminated with exit status=256. 16:25:06.135 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server.

It's tough to test and code at the same time. > Yep, sure is....and look, I know you probably think I'm doing enough already, but if there's anything I can do to get testing bits done, I do find it a refreshing break from writing...which is refreshing break from testing....and I've got the time. Of course, your fight with qsynth & co was all your own there, stuck in the position where you can't test the blessed code you've just written unless you fix that first...catch22. However, I had none of this stuff installed here either when I started out, and relative to -my- experience getting qsynth & co up and running wherein it actually surprized me to work almost out-of-the-box, your experience in what I describe as a 'bad' experience, and it would seem that Kevin has had one of these too...and from my documentor's point of view, this is 'real, live users' experience' information I can trust, and use in the docs to help users out specifically and quickly relative to what linux distro they happen to be using....ie; Kevin and yourself are supplying me this info regarding mandriva, I do my own debian 4.0 testing for this here...etc.. I wanted this stuff to be part of the docs anyway, because Bob already raised this in another thread....but right here, it appears to report Pete's situation back to him. I looked at your kernel config, these are the relevant sections in your linux resulting in the qsynth error message ; //my comments CONFIG_HZ_1000=y CONFIG_HZ=1000 //you DO have the right HZ # CONFIG_PREEMPT_NONE is not set CONFIG_PREEMPT_VOLUNTARY=y # CONFIG_PREEMPT is not set # CONFIG_PREEMPT_BKL is not set //I haven't looked at qsynth code, but my guess is the above //is the show-stopper. 'VOLUNTARY' = normal 'Desktop' preemption //'Low-latency Desktop requires CONFIG_PREEMPT=y (as I do) CONFIG_DEFAULT_IOSCHED="cfq" //not actually how sure this one matters...I use DEADLINE //myself as I'm more interested in linear performance CONFIG_TICK_ONESHOT=y CONFIG_NO_HZ=y CONFIG_HIGH_RES_TIMERS=y //I don't use the 'dynamic ticks' stuff //I believe one needs the HIGH_RES_TIMER set like you have I believe this accounts for what you're seeing with qsynth.

Unlike the IO scheduler which you can change on the fly by echoing values into sysfs, the current kernel preemption model selection is a hardcoded thing which must be selected for inclusion at compile time. I have no idea if they plan to (or can) expose kernel preemption model selection via sysfs, but it sure would get around a lot of this stuff here...

I was looking in the linux tree...apparently, if 'voluntary' is selected this is where the FIFO inherits the priority value it does. the 'low latency' option is a different hunk of code. I imagine if you knew it were coming you could prepare for it just before it was needed, rather than leaving 'room' by the lowering the FIFO priority. It would allow for raising that priority just before/as needed. I think the AMS configure script grep's /proc/config.gz and checks the running kernel config, and issues a warning at the end of configure telling the user what it just found. IIRC, it was a show-stopper until you fixed the kernel setup... I'll shutup about this now....but I got a few FAQ answers solved along the way... Thanks for the latitude ;-).

This is because... [from www.linuxsymposium.org] " Over the past few years, Ingo Molnar and others have worked diligently to turn the Linux kernel into a viable Real-Time platform. Today it is reaching maturity and is making its way into the upstream kernel. Commercial companies are placing more pressure on distributions to offer a Real-Time Linux variant." The patch-set Fedora are using, includes elements of Ingo Molnar's RT patches, and so would seem to confirm this observation. I don't subscribe to LKML (too much traffic), but I can see this RT/lowlatency issue in linux kernels is going to slowly slip out of view...and thus become a 'legacy' issue ...(I hope) Regards, Donald B PS: Today, it seems my son has broken his foot {skateboarding}, so Kevin's not the only one with 'parental challenges' right now ;-) _________________________________________________________________ Search for local singles online @ Lavalife - Click here http://a.ninemsn.com.au/b.aspx?URL=http%3A%2F%2Flavalife9%2Eninemsn%2Ecom%2Eau%2Fclickthru%2Fclickthru%2Eact%3Fid%3Dninemsn%26context%3Dan99%26locale%3Den%5FAU%26a%3D30290&_t=764581033&_r=email_taglines_Search_OCT07&_m=EXT |
