From 9844ab11c763bfed9f054c82366b19dcda66aca9 Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Wed, 14 Oct 2009 00:07:03 +0400 Subject: x86, apic: Introduce the NOOP apic driver Introduce NOOP APIC driver. We should use it in case if apic was disabled due to hardware of software/firmware problems (including user requested to disable it case). The driver is attempting to catch any inappropriate apic operation call with warning issue. Also it is possible to use some apic operation like IPI calls, read/write without checking for apic presence which should make callers code easier.
