Subject: [PULL 04/19] sev/i386: Require in-kernel irqchip support for SEV-ES guests
Date: Mon, 15 Feb 2021 14:16:11 +0100	[thread overview]
Message-ID: <20210215131626.65640-5-pbonzini@redhat.com> (raw)
In-Reply-To: <20210215131626.65640-1-pbonzini@redhat.com>

From: Tom Lendacky <thomas.lendacky@amd.com>

In prep for AP booting, require the use of in-kernel irqchip support. This
lessens the Qemu support burden required to boot APs.
