Hi Jeremy,
I am playing around with MCE stuff, and looking to test MCE handler in
the guest kernel next. Just wondering why we are not installing
MCE handler in the hypervisor in 2.6.37 kernel.
arch/x86/xen/enlighten.c:
cvt_gate_to_trap():
#ifdef CONFIG_X86_MCE
} else if (addr == (unsigned long)machine_check) {
return 0;
#endif
thanks,
Mukesh

In these cases the most likely reason is that nobody with an interest in
MCE has yet stepped up to port the feature to the pvops kernel. Patches
always welcome though ;-)
Ian.

There's a patch from the Intel folks to implement MCE, but I hadn't
added it to my upstream todo list yet. I think it's pretty small, so no
problem to add it - esp if you can actually test it.

Yeah, I can do basic testing if you send or point me to the Intel patch
you mention.
thanks
