Hi guys,
I have a tyan s3992 h2000 with single barcelona amd quad core cpu (the
other cpu socket is empty). cat /proc/cpuinfo shows amd quad core
processor
but core : 1....ive compiled the kernel from scratch with smp and
amd64 + the numa stuff. i also tried debian etchs amd64 smp kernel and
same result.
is amd barcelona quad core cpu not yet supported or is it something else ?
Thanks for any insight. im completely stumped. ive dealt with
mutliprocessing machines before and have a couple of dual cores which
are fine with the
exact same kernel configs. my amd tk-53 x2 turions show 2 cores in cpuinfo....
The bootstrap protocol for Barcelona is a little different from older Opterons,
so an older BIOS that doesn't know the new protocol won't be able to bring up
any CPU other than the bootstrap processor. My wild guess is that this is
what's happening and a BIOS update will fix it, but as Arjan said, please post
dmesg when reporting bugs like this.
