Hi, these psr bits are not fully virtualized and the current usage is not clear (at least to me): sp (secure performance monitor): I don't know how it is currently used by xenoprofile. Isaku have you any tips on it ? di (disable instruction set transition): should it be hard-coded to 1 or should it be settable by the kernel ? si (secure interval timer): should be forced to 0? is (instruction set): same use as di. mc (machine check): should be forced to 1? vm: should be forced to 0. Comments are welcome! Tristan. _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel |
