From mboxrd@z Thu Jan 1 00:00:00 1970 To: linuxppc-dev@lists.linuxppc.org Subject: Time on the MVME2700 Reply-To: minyard@acm.org From: Corey Minyard Date: 08 Dec 1998 21:50:44 -0600 Message-ID: Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: I have Linux 2.1.127 running on a Motorola MVME2700 (750 processor). It's working fine except for timekeeping. It gains about 1.5 seconds every 30 minutes, making time synchronization rather difficult. It is calculating the decrementer frequency value as around 998,736,000 (I removed the hard coding of 998,700,000 that was in there to see what happened. The difference between the two is not significant). However, by my calculations the frequency should be about 1,000,000,000. This is all in arch/ppc/kernel/time.c. I'm going to hard-code it to that value to see what happens, but has anyone else seen this? Unfortunately, I don't remember the processor frequency offhand and I'm at home now. -- Corey Minyard Internet: minyard@acm.org Work: minyard@nortel.ca UUCP: minyard@wf-rch.cirr.com [[ This message was sent via the linuxppc-dev mailing list.
