From 927d5a1d98ff9177ec29e883c5361e0d247291d8 Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Thu, 15 Sep 2016 15:15:59 +0800 Subject: pc: apic: introduce APIC macro MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce a new APIC macro to replace APIC_COMMON macro in hw/intc/apic.c in order to capture access LAPIC in qemu even if LAPIC is emulated in kvm.
