From ac8ebd0e73774c83bfa5cb3dd460c662000e0d19 Mon Sep 17 00:00:00 2001 From: Raul E Rangel Date: Mon, 20 Aug 2018 11:14:44 -0600 Subject: libpayload/arch/x86: Add support for initializing the APIC This is just the bare minimum required to initialize the APIC. I only support xAPIC and chose not to support x2APIC. We can add that functionality later when it's required. I also made the exception dispatcher call apic_eoi so that the callbacks won't forget to call it. BUG=b:109749762 TEST=Booted grunt and verified that depthcharge continued to function and that linux booted correctly. Also verified GDB still works.
