RFC: http://www.spinics.net/lists/kvm/msg132036.html This series allows userspace to create and send interrupts to VCPUs with APIC ID > 255. v1: 32 bit API extensions now use a toggleable capability called KVM_CAP_X2APIC_API. * new [1/11], loosely related and should have been posted long ago * [2/11] improved comment for kvm_apic_map_get_dest_lapic() [Peter] * [3/11] use round_up [Peter] * [6/11] drop big endian format in lapic get/set ioctl [Paolo] * [6/11] exclude APICv optimization of APIC ID register * [6/11] rename __kvm_apic_state_fixup() parameter * new [7/11], split from the previous patch * [8/11] added r-b [Peter] * [10/11] rewritten with a toggleable capability [Paolo] * [10/11] dropped MSI_ADDR_EXT_DEST_ID to enforce reserved bits Latest Linux, FreeBSD, and Windows run fine, but I haven't tested VFIO. Linux works even with APIC ID over 255. (QEMU and seabios patches to achieve that are not yet posted.)
