Subject: [PATCH 9/9] KVM: x86: Hide KVM_IRQCHIP_KERNEL behind CONFIG_KVM_IOAPIC=y
Date: Fri, 5 Dec 2025 16:43:11 -0800 [thread overview]
Message-ID: <20251206004311.479939-10-seanjc@google.com> (raw)
In-Reply-To: <20251206004311.479939-1-seanjc@google.com>
Enumerate KVM_IRQCHIP_KERNEL if and only if support for an in-kernel I/O
APIC is enabled, as all usage is likewise guarded by CONFIG_KVM_IOAPIC=y.
