From a39e356458335418973ca7d388c02712145cd177 Mon Sep 17 00:00:00 2001 From: Jason Baron Date: Wed, 14 Nov 2012 15:54:01 -0500 Subject: [PATCH] pc: Move ioapic_init() from pc_piix.c to pc.c Move ioapic_init() from pc_piix.c to pc.c, to make it a common function. Rename ioapic_init() -> ioapic_init_gsi(). Move to pc.h so q35 can use them as well.
