Subject: adding accuracy to random timers on PPC - new config option or runtime  overhead?
Date: Wed, 22 Aug 2001 13:31:39 -0400	[thread overview]
Message-ID: <3B83EC7B.B10F59C6@nortelnetworks.com> (raw)


I'm looking at putting in PPC-specific code in add_timer_randomness() that would
be similar to the x86-specific stuff.

The problem is that the PPC601 uses real time clock registers while the other
PPC chips use a timebase register, so two different versions will be required.
Should I try and identify at runtime which it is (which would be extra
overhead), or should I add another config option to the kernel?

Thanks,

Chris
