Subject: 32 kHz timer granularity when CONFIG_NO_HZ is enabled
Date: Wed, 22 Oct 2008 16:13:02 +0300 [thread overview]
Message-ID: <48FF26DE.4060107@nokia.com> (raw)
Hi,
I have OMAP 3 and I'm using the 32 kHz timer, CONFIG_OMAP_32K_TIMER_HZ
is set to 128 and CONFIG_NO_HZ is enabled. Many OMAP-based boards in
arch/arm/config seem to have this kind of default configuration.
This has the effect that for example msleep(1) sleeps much longer than
intended, between 7,8 and 15,6 ms, for no apparent good reason.
I'm just wondering whether all this is intentional. :-)
