Imagine I've passed "disableapic" so I expect as many as possible apic-related code would not pass thru execution. Now we would have (say for IBM Summit) acpi_parse_madt default_acpi_madt_oem_check summit_acpi_madt_oem_check mark_tsc_unstable setup_summit Dunno if it harmless or no but it changes kernel behaviour. cpu_has_apic cleared if disableapic option (which is early param) passed to kernel. Just a note. Didn't walk thru all ways. Yeah, that occured to me over the weekend. Some of those cpu_has_apic tests should probably be replaced with explicit tests to see if noapic was specified. I'll go over it with that in mind. Thanks, J _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
