From 03d2249ea60818e97475ac529aa183cf130935bb Mon Sep 17 00:00:00 2001 From: =?utf8?q?Radim=20Kr=C4=8Dm=C3=A1=C5=99?= Date: Thu, 12 Feb 2015 19:41:31 +0100 Subject: [PATCH] KVM: x86: use MDA for interrupt matching MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In mixed modes, we musn't deliver xAPIC IPIs like x2APIC and vice versa. Instead of preserving the information in apic_send_ipi(), we regain it by converting all destinations into correct MDA in the slow path. This allows easier reasoning about subsequent matching. Our kvm_apic_broadcast() had an interesting design decision: it didn't consider IOxAPIC 0xff as broadcast in x2APIC mode ... everything worked because IOxAPIC can't set that in physical mode and logical mode considered it as a message for first 8 VCPUs. This patch interprets IOxAPIC 0xff as x2APIC broadcast.
