* chrt: add support for SCHED_RESET_ON_FORKAdrian Knoth2010-02-021-0/+11
| | | | | | | | | | | | | | | | From 9262c9832134f8a33ac2ea2854dc6d20acc712d1 Mon Sep 17 00:00:00 2001 From: Adrian Knoth <adi@drcomp.erfurt.thur.de> Date: Tue, 2 Feb 2010 16:57:23 +0100 Subject: [PATCH] Add support for SCHED_RESET_ON_FORK to chrt SCHED_RESET_ON_FORK has been added in 2.6.31. If a thread has this flag set, chrt reports "unknown" policy, which is confusing. The patch adds support for this new flag. It will (can) only be applied to SCHED_FIFO or SCHED_RR, so there's no need to catch the other scheduling policies. Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de>

* build-sys: rename to _execdirKarel Zak2009-07-041-3/+3
| | | | | | | | | | | | The variable name "usrlibexecdir" is very confusing (because we have /usr/libexec). The "exec" prefix is required for user-defined directories, see http://www.gnu.org/software/hello/manual/automake/The-Two-Parts-of-Install.html#The-Two-Parts-of-Install This patch renames all usr*execdir variables to usr*_execdir.

* ionice: Allow setting the none classJakob Unterwurzacher2009-05-272-3/+6
| | | | | | | | | | Allow users to set the "none" class on processes. Using the none class has the distict advantage that the io priority is inherited from the cpu nice level. Update the man page to reflect the change. Signed-off-by: Jakob Unterwurzacher <jakobunt@gmail.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* chrt: don't assume SCHED_BATCH and SCHED_IDLE existAurelien Jarno2009-05-072-4/+27
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

* ionice: add strtol() checks, cleanup usage text and man pageKarel Zak2008-09-062-21/+45
| | | | | | | | | | | | | | | | | | | * cleanup usage() output * check strtol(); don't ignore wrong command line options The original ionice design was a little broken, because it was possible to specify a PID and also a COMMAND: ionice -c2 -p 123 /bin/foo but the command /bin/foo was executed without requested scheduling class. That's stupid behaviour. Now you have to use "-p PID" **or** COMMAND, but not both. Nothing is ignored and all options are checked. Signed-off-by: Karel Zak <kzak@redhat.com>

* ionice: add -t optionLubomir Kundrak2008-06-162-4/+15
| | | | | | | | | | | | | | | | | | | | | | | This patch allows "tolerant" behavior, i.e. proceeding even if priority could not be set. This might be of use in case something (selinux, old kernel, etc.) does not allow the requested scheduling priority to be set. This could be to some extend done as follows: ionice -c3 command || command but the downside is that one could not really tell if what failed was setting priority or command itself, which could result in duplicate command run. This patch solves the situation, so that user can do ionice -t -c3 command Addresses-Red-Hat-Bugzilla: #443842 Signed-off-by: Lubomir Kundrak <lkundrak@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* taskset: independent of hardcoded NR_CPUS max.Cliff Wickman2007-06-191-33/+168
| | | | | | | | | | | | | | | | | | | | This patch makes the taskset command independent of the system's maximum number of cpus (CONFIG_NR_CPUS). The maximum for CONFIG_NR_CPUS is a moving target. With this patch the size of the systems's cpumask_t is gotten from sched_getaffinity(2). This patch uses variable length bitmasks borrowed from Paul Jackson's variable size bitmask routines (hence I kept his copyright notice). This replaces the use of the glibc CPU_SETSIZE, CPU_SET, CPU_ZERO and CPU_ISSET macros which depend on a hardcoded size for cpu_set_t. (also fixes one little nit: the -V option is "-v" in the built-in help, so changed the built-in help) Signed-off-by: Cliff Wickman <cpw@sgi.com> Signed-off-by: Karel Zak <kzak@redhat.com>
