Subject: [PATCH v2 04/16] KVM: x86: hyper-v: Introduce kvm_hv_synic_auto_eoi_set()
Date: Tue, 5 Dec 2023 11:36:18 +0100 [thread overview]
Message-ID: <20231205103630.1391318-5-vkuznets@redhat.com> (raw)
In-Reply-To: <20231205103630.1391318-1-vkuznets@redhat.com>
As a preparation to making Hyper-V emulation optional, create a dedicated
kvm_hv_synic_auto_eoi_set() helper to avoid extra ifdefs in lapic.c
No functional change intended.
