VIA Cyrix C3/MIII CPU

VIA Cyrix C3/MIII CPU

[David Chow]

Dear all,

I am testing my board using the Cyrix C3 733 CPU. After installing the
newly compiled kernel 2.4.7 , after the message "freeing unsused memory"
and hangs... anyone has this before? I am using the new VIA 694T chipset
. Or anyone test the Cyrix C3 CPU? Thanks

regards,

David

Seems like your init is hanging?
Are you sure you haven't a glibc compiled for 686?

Ok.. it seem's you are right because the root file system is mountd
readonly... okay!. thanks.. I will reinstall the glibc and see if that
fixes... okay.

What target did you compile your kernel for ?
Choose either CyrixIII or 586 or less, as it's missing the CMOV
instruction.  My 866 has been completely stable during tests the
last week or so, even with me playing with the multiplier adjusting
MSRs etc..

regards,

Dave.

Sounds like a configuration error. Make sure you configured your
kernel for a C3 (CONFIG_MCYRIXIII) or a P5MMX -- NOT a regular 686.
Same goes for user-space libraries etc: they MUST NOT be compiled
for a 686-class machine.

(VIA C3 pretends to be a 686 but does not implement the CMOV
conditional move instruction. In theory this is ok because CMOV
is officially optional, but gcc uses CMOV when compiling for
686 since every other known 686 has it.)
