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

Patches always welcome though ;-) Ian. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I think it''s pretty small, so no problem to add it - esp if you can actually test it.
