Subject: [PATCH v13 07/19] x86/msr: Add variable MTRR base/mask and x2apic ID registers
Date: Fri, 28 Mar 2025 16:08:02 -0700 [thread overview]
Message-ID: <20250328230814.2210230-8-ross.philipson@oracle.com> (raw)
In-Reply-To: <20250328230814.2210230-1-ross.philipson@oracle.com>
Add the MSR values required by Secure Launch to locate particular CPU cores
during application processor (AP) startup, and restore the MTRR state after
an Intel TXT launch.
