Subject: [patch] make pit clocksource continuous
Date: Sun, 13 May 2007 03:18:52 +0400 [thread overview]
Message-ID: <46464B5C.2080302@aknet.ru> (raw)

Hello.
Without the attached patch, I wasn't able
to get the PIT to work as a clocksource for
high-res timers.
I don't know whether the patch is correct,
but I tested it and it works.
Can someone please tell me what exactly
does this flag mean? google reveals nothing
sensible to me, sorry...

Set CLOCK_SOURCE_IS_CONTINUOUS flag for the PIT clocksource
