Hi,
that's interesting news.
Can You write more about the CPU usage/percentage while doing some audio
playback please?
Any jackd XRUN hiccups or other holdups?
Thanks for sharing Your experiences here.
Regards,
Crypto.

I'm happy to report that I am writing this from my
new EEE softsynth,
running an RT-patched kernel, jackd, and several softsynths.
System info, if anyone is interested, is here:

I'm stunned that this even works, but it does, and astoundingly well!
I've got cpufreq userspace governor, manually set to maximum CPU speed
(1.6Ghz). I'm using the crappy built-in hda-intel card, and not even at its
native frame rate (I'm at 44100, not 48000). I'm also using a version of
jackd that has been reported to be sub-optimal (0.109.2-3).
The last missing peices were the rt2860sta and atl1e drivers, which I built
in a few minutes from source packages already in Debian-EEE (make-kpkg
modules_image .... done!). Many thanks for the patch to fix the alsa_seq;
it works perfectly in the 2.6.26.8-rt12 kernel.
I now have a usable Linux synth for live performance, which weighs 1.45KG,
fits in a backpack, runs all my crucial sounds, draws about 1 amp at
maximum CPU speed, and reportedly will run 6 hours on its own internal
battery. With the cheap Edirol PCR-30 I bought a few months ago, and a
small battery-powered amp, I can do street performances now-- or other
casual gigs-- while lugging a minimum amount of gear. I'm thrilled.
I still have to compile a couple packages that aren't in Debian: my own few
utilitiies, AZR3-JACK, klick, WhySynth, and a few others, and I'm set to
go. I also want to recompile the kernel again to change the timer 1000Hz
not 250Hz.
0.109 works, but what is the most stable/reliable/efficient version of JACK
I should look into. 0.116?
