cyrix III by via

[Eric Estabrooks]

I am not a subscriber to this list, but I thought this was important
information (which you might already have).

The cyrixIII chips by via have the centaur vendor id which causes the
identify_cpu call in arch/i386/kernel/setup.c to fail.  It is probably
reasonable for it to have the centaur id as via owns centaur as well.  I
just replaced the centaur_model call with the cyrix_model one, but I
know that I am using a cyrix chip.

A test probably needs to be added in the centaur_model section to test
for the cyrixIII in disguise.

The error is a general protection fault.

Sorry if this is old hat,

Its fairly new hat. VIA cyrix III is a next generation IDT winchip (VIA bought
both the winchip stuff and the Cyrix stuff). 2.2.18 should handle the
winchip properly

2.2.18pre, and 2.4.0test have contained this test for some time now.
However, I've heard no reports of it working or not due to no-one having
the necessary hardware to test it.

Are you saying the latest versions still don't recognise it?
What kernel version did you try ?

Davej.
