At least one BIOS has been seen to include such entries even though the relevant specs require that X2APIC entries only be used for CPUs with an APIC ID >= 255. This was tested on a system with "plain" local APIC entries in the MADT to ensure no regressions, but it has not yet been tested on a system with X2APIC entries in the MADT. Currently such systems do not boot at all, and with this change they might now boot correctly. Differential Revision: https://reviews.freebsd.org/D2521 Reviewed by: kib MFC after: 2 weeks |
