On 8 May 2006, at 15:18, Jan Beulich wrote: If the many-core appearance is a problem then we could synthesise different physical IDs for VCPUs (probably by forcing physical ID to VCPU number).This is what the patch does (it simply overrides whatever identify_cpu() provided). Why add the copy from boot_cpu_data, or the call to identify_cpu(), at all? We already initialise the cpu_data in smp_prepare_cpus(), and we set up the cpu_to_apicid array at the same time. Why not lie about cpu_data->apicid, and set phys_proc_id[cpu], at the same time in the same function? That would be a one- or two-liner, plus maybe your modification of booted_cores if that's still needed. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
