Hi everyone, I'm currently looking into hotplugging CPUs. This exclusively with linux-guests and linux-host. I have found some (conflicting) information about this on the net. As far as I read: * seabios doesn't support SMP (but why does the linux-guest show multiple cpus?) * there is no uniform way of informing the linux kernel that a cpu has added (Found references to a unisys way of doing it though, which seems to be still implemented) * the kernel needs the acpi tables to determine how many cpus it has, thus the support in the bios would involve an aml-compiler to hot-compile new acpi tables. 1) *If* I understood this right, wouldn't it be feasible to patch the linux-kernel to forego the check on the acpi tables and read them straight from a kvm provided area (even in a kvm-proprietary format?). Then at least the aml-compiler wouldn't be necessary, or am I wrong there? 2) Assuming I understood this right, I'd further assume, I could create some sort of kernel event (udev) to initiate a cpu_starting event, couldn't I? Some feedback would be much appreciated ;) Conrad -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
