-Subject: [PATCH 03/18] apic: fixup fallthrough to PIC
-
-Commit 0e21e12bb311c4c1095d0269dc2ef81196ccb60a [Don't route PIC
-interrupts through the local APIC if the local APIC config says so.]
-missed a check to ensure the local APIC is enabled. Since if the local
-APIC is disabled it doesn't matter what the local APIC config says.
-
-If this check isn't done and the guest has disabled the local APIC the
-guest will receive a general protection fault, similar to what is seen
-here:
-
-https://lists.gnu.org/archive/html/qemu-devel/2012-12/msg02304.html
-
-The GPF is caused by an attempt to service interrupt 0xffffffff. This
-comes about since cpu_get_pic_interrupt() calls apic_accept_pic_intr()
-(with the local APIC disabled apic_get_interrupt() returns -1).
-apic_accept_pic_intr() returns 0 and thus the interrupt number which
-is returned from cpu_get_pic_interrupt(), and which is attempted to be
-serviced, is -1.
