Hi all
I ran amarok and ossxmix in realtime.
Following is the display from the top command.
PID USERNAME THR PRI NICE SIZE RES STATE C
TIME WCPU COMMAND
1047 test 6 96 0 72524K 29776K ucond 0
1:06 0.15% amarokapp
940 root 1 96 0 173M 45560K select 0
1:36 0.00% Xorg
1065 test 1 44 r0 14528K 7336K select 0
0:12 0.00% ossxmix
Following are the rtprio output for those processes:
$ rtprio 1047 [for amarokapp ]
rtprio: realtime priority 0
$ rtprio 1065 [for ossxmix ]
rtprio: realtime priority 0
$ rtprio 940 [ for Xorg ]
rtprio: normal priority
Why does it show 96 under the PRI column for
amarokapp? And it doesn't show r0 for NICE for
amarokapp. Does it mean amarokapp downgraded to normal
priority? But while amarok is playing rtprio shows it
is still realtime. which one is right?
Best Regards
Unga
