* chrt: add --reset-on-forkKarel Zak2010-02-021-0/+14
| | | | | | | | | | | | | | | This new option allows to set SCHED_RESET_ON_FORK flag for FIFO and RR policies. Example: $ chrt --fifo --reset-on-fork 1 /bin/bash $ schedutils/chrt --pid $$ pid 31579's current scheduling policy: SCHED_FIFO|SCHED_RESET_ON_FORK pid 31579's current scheduling priority: 1 Signed-off-by: Karel Zak <kzak@redhat.com>
* chrt: don't assume SCHED_BATCH and SCHED_IDLE existAurelien Jarno2009-05-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | SCHED_FIFO, SCHED_OTHER, SCHED_RR are part of POSIX 1003.1b Process Scheduling, so it is correct to assume they always exists. SCHED_BATCH and SCHED_IDLE are Linux specific, we should not assume they exists. Defining SCHED_BATCH and SCHED_IDLE to random values (ie the ones found on Linux systems) is not an option as they may *collide* with the one of other systems. For example on GNU/kFreeBSD we have: #define SCHED_RR 3 and on Linux we have: #define SCHED_BATCH 3 [kzak@redhat.com: - add "Linux specific" notes to chrt.1 - add a note about BATCH and PR conflict to this commit message] Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Karel Zak <kzak@redhat.com>
