But the arch timer register VCTOFF normally is very different between the two cpus in A20 afer hardware reset, so SMP Cpus will see different time tick. It will cause kernel crash currently. You have two choices to fix it: 1 Simpley use physical arch timer, 2 Set VCTOFF to same value for each cpu in bootloader. The first choice will cause some other problem for kernel, especially for KVM, guest OS want to use virtual arch timer. So the second choice is perfect. So if you want to use arch timer for smp cpu tick, you must ensure you bootload have set same VCTOFF for all cpus.\n" @@ -35,4 +46,4 @@ "-- \n" 1.8.1.2 -48b981af268b1cd4c3384820bee53c19deffd0157309c6dc5ad50d997a4a6193 +5893c09fd21835417eeb452623022bd2a345cda05fc8aa28dd0b80cbe1f1c097
