Author: kib Date: Wed Mar 18 21:24:34 2020 New Revision: 359090 URL: https://svnweb.freebsd.org/changeset/base/359090
Log: Widen the stored io_apic_id to 8 bits. It seems that the newer Intel chipset did that, and Linux reads 8 bits. The only detail is that all seen datasheets, even under NDA, claim that io apic id is 4 bits.
