Although I'm not sure future model will crease the number of them, It would be safe to keep pmd/pmc separeted from vcpu_guest_context. Anothor approach would be that only generic part of pmcs and pmds (pmc0-7, pmd0-7 according to perfmon_generic.h) are included in vcpu_guest_contest. Model specific part must be handled somehow anyway. -- yamahata _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel
