Subject: [Qemu-devel] xAPIC version register for >P4/Xeon CPUs
Date: Mon, 03 Jan 2011 16:31:47 +0100 [thread overview]
Message-ID: <4D21EBE3.2060808@salomon.at> (raw)
Hi!
Another question: Shouldn't the APIC version be 0x14 for CPUs since P4/Xeon? At least according to the Intel docs, since then the xAPIC is used, which has 0x14 as version (see intel manuals, vol 3a "10.4.8 Local APIC Version Register". reading the APIC version register yields 0x11 for all CPUs on qemu currently (so local APIC, not local xAPIC).
is this inteded? if yes, why? (it is incompatible with the specs, right?).
Regards, Markus
