From cbd27b8ced4b1888c93f69b4dd108a69ac4d733f Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 12 Oct 2005 11:39:33 +1000 Subject: [PATCH] [PATCH] ppc32: Fix timekeeping Interestingly enough, ppc32 had broken timekeeping for ages... It worked, but probably drifted a bit more than could be explained by the actual bad precision of the timebase calibration. We discovered that recently when somebody figured out that the common code was using CLOCK_TICK_RATE to correct the timekeeing, and ppc32 had a completely bogus value for it. This patch turns it into something saner. Probably not as good as doing something based on the actual timebase frequency precision but I'll leave that sort of math to others. This at least makes it better for the common HZ values.
