Here's a printout using the just installed procps-ng ps, covering
everything the tweakers heart likes to see.
Code:
--------------------
ps -eLo psr,pid,tid,pri,rtprio,comm,command
1 10378 10378 87 47 squeezelite-cus
/mnt/mmcblk0p2/tce/squeezelite-custom -n sc1 -o hw:CARD=AudioDOP2,DEV=0 -a 160
4 1 -b 60000 400000 -c pcm,flac,mp3 -p 48 ...
0 10378 10385 87 47 stream
/mnt/mmcblk0p2/tce/squeezelite-custom -n sc1 -o hw:CARD=AudioDOP2,DEV=0 -a 160
4 1 -b 60000 400000 -c pcm,flac,mp3 -p 48 ...

1 10378 10417 87 47 decode
/mnt/mmcblk0p2/tce/squeezelite-custom -n sc1 -o hw:CARD=AudioDOP2,DEV=0 -a 160
4 1 -b 60000 400000 -c pcm,flac,mp3 -p 48 ...
--------------------
As you see, the output thread is hooked up to CPU3 and runs a slightly
higher prio then the rest of squeezelite.
No need for top or alike to get the picture.
Regarding the CPU0 isolation.
Phil Elwell, one of the key kernel developers, took the ball. His 2nd
response about the subject ( "Do you need it?" )
implied to me, yes, it's an issue, could be a bit difficult to get
resolved though.
I asked him if it's that what he means. Let see what he says. It seems
for the time being CPU0 isolation is no longer possible on RPis.
Enjoy.
