Subject: [PATCH v16 24/38] x86/msr: Add variable MTRR base/mask and x2apic ID registers
Date: Fri, 15 May 2026 14:13:56 -0700 [thread overview]
Message-ID: <20260515211410.31440-25-ross.philipson@gmail.com> (raw)
In-Reply-To: <20260515211410.31440-1-ross.philipson@gmail.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.
