Description mchampig 1999-10-11 14:29:01 UTC
Please add the "-J" command line arg in the /etc/rc.d/rc.sysinit file when setting arguments for the "clock" command. This needs to be passed on Alpha Jensen architecture in order to set the clock correctly. There is a line which sets "CLOCKDEFS" when it is known we are using ARC. You have the "-A" you just need to add "-J". To detect we are on Alpha Jensen, you should be able to use /proc filesystem or some other means. This is an easy fix...please apply it so Jensen owners can have the priviledge of a real time clock. :-) This bug has been around since RH 3.0.3!!!!
Comment 1 Bill Nottingham 1999-10-11 15:20:59 UTC
Can you send me the output of /proc/cpuinfo on a Jensen?
Comment 2 Bill Nottingham 1999-10-11 16:26:59 UTC
Eh, nevermind. Fixed in initscripts-4.52-1, assuming grepping for Jensen in /proc/cpuinfo is enough.
Comment 3 mchampig 1999-10-12 15:18:59 UTC
Good job! Yes, grepping for "Jensen" will pick it up in the system type field. Just one thing to note...I had a look at the clock src.rpm and this fix is already in the binary! It does the same check internally for the Jensen. So that means there is still a bug lurking in the clock code. I will fix this and send a patch. You might want to keep the "-J" hack in the init script though, since some older RH users might not have the /proc filesystem with older kernels. Better to be safe than sorry, but "-J" is obsolete since we have a way at runtime to determine system types now.
Comment 4 Bill Nottingham 1999-10-13 17:10:59 UTC
Should be fixed in clock-1.1-7, in the next Raw Hide release.
Comment 5 mchampig 1999-10-13 18:01:59 UTC
By the way, I sent you an updated patch for clock-alpha.c. It will allow the clock to run correctly on Jensen. The 20 year offset problem still remains but that is beyond RH to fix since it's a known bug on very old firmware. The Jensen needs to use /dev/port to access the clock hardware, so the fix will only affect the Jensen. This is detected at runtime by the clock image. Thanks for applying the patch! If you have any questions or need further testing let me know. P.S. If you need a Jensen I may be able to have one donated to RH. Let me know and I'll put you in touch with someone. These boxes are flooding the market with the demise of NT on Alpha so it's in RH best interest to support it. ;-)
