Subject: [edk2-devel] [PATCH v2 2/5] UefiCpuPkg/MpInitLib: Add support for multiple HOBs to GetBspNumber()
Date: Tue, 20 Feb 2024 18:49:36 +0100 [thread overview]
Message-ID: <20240220174939.1288689-3-kraxel@redhat.com> (raw)
In-Reply-To: <20240220174939.1288689-1-kraxel@redhat.com>
Rename the MpHandOff parameter to FirstMpHandOff. Add a loop so the
function inspects all HOBs present in the system.
