Looking at the specfile, here's what realtime-setup gets you:
|
||||
|
||||
1. Create a realtime group:
|
||||
/usr/sbin/groupadd -f -g 71 realtime
|
||||
2. Turns on "panic on hung task":
|
||||
sysctl -w kernel.hung_task_panic=0 >/dev/null 2>&1
|
||||
3. Sets "hung task" threshold to 600 seconds:
|
||||
sysctl -w kernel.hung_task_timeout_secs=600
|
||||
4. Installs and enables systemd realtime-setup service file:
|
||||
install -m 644 -D realtime-setup.service /usr/lib/systemd/system/realtime-setup.service
|
||||
systemctl enable realtime-setup
|
||||
5. installs realtime rules in /etc/security/limits.d/realtime.conf:
|
||||
@realtime soft cpu unlimited
|
||||
@realtime - rtprio 99
|
||||
@realtime - nice -20
|
||||
@realtime - memlock unlimited
|
||||
6. install udev rules in /etc/udev/rules.d/99-rhel-rt.rules
|
||||
# udev rules specific to RHEL-RT Realtime kernel
|
||||
# insure /dev/rtc points to /dev/rtc0
|
||||
# we use PROGRAM rather than SYMLINK because there is
|
||||
# a (good) possibility that a /dev/rtc device file
|
||||
# already exists and we want to replace it (hence the
|
||||
# ln -sf)
|
||||
KERNEL=="rtc0", PROGRAM+="/bin/ln -sf rtc0 /dev/rtc"
|
||||
# Give permission to the realtime group to write a zero to /dev/cpu_dma_latency
|
||||
# This will tell the power management system not to transition to a high cstate
|
||||
KERNEL=="cpu_dma_latency", GROUP="realtime"
|
||||
# Give permission to the realtime group to read the per cpu msr and cpuid
|
||||
# registers. This is needed by cyclictest in rt-tests when using the new
|
||||
# feature to read the smi counters. This is necessary but not sufficient
|
||||
# A program that wants to access these registers will also need CAP_SYS_RAWIO
|
||||
SUBSYSTEM=="msr", GROUP="realtime", MODE="0640"
|
||||
SUBSYSTEM=="cpuid", GROUP="realtime", MODE="0640"
|
||||
7. install sysconfig rules for RT in /etc/sysconfig/realtime-setup
|
||||
#
|
||||
# Decide whether to turn off SLUB cpu_partial support
|
||||
#
|
||||
SLUB_CPU_PARTIAL="off"
|
||||
8. install script to turn off SLUB cpu-partial support:
|
||||
/usr/bin/slub_cpu_partial_off
|
||||
9. install kernel-is-rt script in /usr/sbin/kernel-is-rt
|
||||
10. install a C binary that enables socket timestamping:
|
||||
install -m 755 -D -s realtime-entsk /usr/sbin/realtime-entsk
