Ah, looks like half the MCE stuff is not even hooked up the mce boot parameter. Well, I expect Christoph Egger can help: he implemented a lot of the MCE mechanism, and especially the AMD parts. I think the mce boot parameter should, when disabled, cause the MCE feature bits to be removed from Xen's copy of CPUID feature flags. That would easily disable all MCE logic throughout Xen. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
