Subject: [PATCH 05/12] KVM: SVM: Update avic_kick_target_vcpus to support 32-bit APIC ID
Date: Tue, 5 Apr 2022 18:08:48 -0500	[thread overview]
Message-ID: <20220405230855.15376-6-suravee.suthikulpanit@amd.com> (raw)
In-Reply-To: <20220405230855.15376-1-suravee.suthikulpanit@amd.com>

In x2APIC mode, ICRH contains 32-bit destination APIC ID.
So, update the avic_kick_target_vcpus() accordingly.
