Subject: [PATCH v4 2/6] sev/i386: Require in-kernel irqchip support for SEV-ES guests
Date: Fri, 25 Sep 2020 14:03:36 -0500 [thread overview]
Message-ID: <dcbeb6aba051f10b8e6e8a0b90e26101eb3ee526.1601060620.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1601060620.git.thomas.lendacky@amd.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.
