Re: [Jack-Devel] smallest embedded platform for Jack
Dear Patrick,
I built jack from the latest git on a armhf platform I'm currently using
with both the defaults and with --ports-per-application=8 --clients=8
but obtained no change in virtual memory used by jackd2 at runtime.
Detail:
./waf configure --prefix=/usr --classic
--libdir=/usr/lib/arm-linux-gnueabihf --alsa --ports-per-application=8
--clients=8
./jackd -P62 -t2000 -dalsa -dhw:0 -r48000 -p128 -n2 -s -i4 -o4 &
cat /proc/4967/status:
VmPeak: 92908 kB
VmSize: 92908 kB
VmLck: 80356 kB
VmPin: 0 kB
VmHWM: 89028 kB
VmRSS: 89028 kB
VmData: 8424 kB
VmStk: 136 kB
VmExe: 16 kB
VmLib: 3476 kB
VmPTE: 98 kB
VmSwap: 0 kB
Threads: 4
Same goes if I run the default version. Maybe I got something wrong?
