[Xen-devel] [PATCH] provide detailed physical CPU info for dom0 MCE handling
The attached patch introduces a hypercall to provide detailed physical CPU information for dom0. While there is already a physinfo call, much more detailed information is needed for dom0 to have enough knowledge of the system to be able to deal with the MCE information provided when an actual exception occurs, and to store this information so that it can be used across reboots. Most of the needed information is gleaned from the already present global cpu info structures. A few things are collected at call time. This patch also bumps the mc_apicid in the global MC info field to 32bits, for future extension and better alignment. This patch was discussed with and agreed upon by both the AMD and Intel engineers working on MCE for Xen. - Frank _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
