Subject: CONFIG_HZ=250 on Kirkwood
Date: Fri, 11 Oct 2013 12:44:16 +0200 [thread overview]
Message-ID: <5257D680.6040400@keymile.com> (raw)
Hi,
according to a statement from Russell King:
commit b28748fb5d21d5d64c9ce31579ffbbd41f317042
Author: Russell King <rmk+kernel@arm•linux.org.uk>
Date: Sun Feb 17 14:40:33 2013 +0000
ARM: add SCHED_HRTICK config option
As we don't include kernel/Kconfig.hz as this defines HZ values
unsuitable for ARM platforms, add the SCHED_HRTICK to properly
configure
the scheduler for hrtimer operation.
Signed-off-by: Russell King <rmk+kernel@arm•linux.org.uk>
and to arch/arm/Kconfig:
config HZ
int
default 200 if ARCH_EBSA110 || ARCH_S3C24XX || ARCH_S5P64X0 || \
ARCH_S5PV210 || ARCH_EXYNOS4
default AT91_TIMER_HZ if ARCH_AT91
default SHMOBILE_TIMER_HZ if ARCH_SHMOBILE
default 100
the only safe value for CONFIG_HZ on Kirkwood would be 100.
We would like to use CONFIG_HZ=250 on our Kirkwood devices and NOT use
the SCHED_HRTICK feature.
Does anyone have know whether (and why) this would be a bad idea?
Thanks a lot!
Gerlando
