Florian, can you give a way to easily get the system arch for any of the arch
listed above ?
(for instance, results of uname -sm)
=================== BUG #1593: FULL BUG SNAPSHOT ===================
Submitted by: fweps Project: Package DataBase View
Submitted on: 2002-Nov-03 21:33
Category: core Severity: 3
Bug Group: None Resolution: None
Assigned to: fweps Status: Open
Summary: CPUSPEED detection is intel-specific
Original Submission: The way we currently determine CPUSPEED is intel-specific.
Sadly, /proc/cpuinfo varies wildly on different
architectures and sometimes doesn't even contain CPU
frequency.
Grepping for "cpu MHz" works on i386 and ia64.
I'll collect samples of /proc/cpuinfo for all
architectures I have access to, and come up with a cool
solution.

Or maybe we should get over it and set a 7s sleep for everybody ?

Hum, this find problem will be very painy.
For instance, with the itanium bipro, we got only values of processors one by
one.
And no way to be sure that it will be portable in the future...
I havent received any answer to my bug report to gnu findutils...
Maybe we should use something else that find ? (as possible, usual on GNU/Linux
or other Free OSes)

There is a table for rough bogomips|-->clock mappings at
http://www.clifton.nl/bogomips-2.html#ss2.2
Maybe this will become useful.
I'll do a tour of the Debian project machines and collect all
/proc/cpuinfo listings later tonight.

That's correct but I do not know how much bogomips should consider as critical
for find.
P120 = approx 240 bogomips
P350 = approx 700 bogomips
bi-P800 = apprx 3200 bogomips
http://savannah.gnu.org/phpsysinfo/
It could help to determine that.

Hi, I wander if the 'bogomips' line is more "portable".
If it is, the bogomips counter could be used as an
approximation of the computational power instead of the
Mhz.

Ok.
If GNU find wasnt buggy, this part would be absolutely usefull... What a pain.
Currently, if we do not deal with linux kernel, we skip the CPUSPEED and
consider that we need to do the 7s sleep.
We should maybe test also whether we deal with an arch. we know how to get the
CPU frequency or not (in this case, the test would be also skipped).
