From 49df6397edfc5a8ba8ca813b51fb9729d8e94b40 Mon Sep 17 00:00:00 2001 From: Steve Rutherford Date: Wed, 29 Jul 2015 23:21:40 -0700 Subject: KVM: x86: Split the APIC from the rest of IRQCHIP. First patch in a series which enables the relocation of the PIC/IOAPIC to userspace. Adds capability KVM_CAP_SPLIT_IRQCHIP; KVM_CAP_SPLIT_IRQCHIP enables the construction of LAPICs without the rest of the irqchip. Compile tested for x86.
