Subject: [PATCH v2 02/11] OvmfPkg/AmdSev: use GenericQemuLoadImageLib in AmdSev builds
Date: Tue, 6 Jul 2021 08:54:52 +0000 [thread overview]
Message-ID: <20210706085501.1260662-3-dovmurik@linux.ibm.com> (raw)
In-Reply-To: <20210706085501.1260662-1-dovmurik@linux.ibm.com>
Newer kernels support efistub and therefore don't need all the legacy
stuff in X86QemuLoadImageLib, which are harder to secure. Specifically
the verification of kernel/initrd/cmdlien blobs will be added only to
the GenericQemuLoadImageLib implementation, so use that for SEV builds.
