Subject: [PATCH 2/2] Drivers: hv: Kconfig: Add HYPERV_VTL_MODE dependencies
Date: Thu, 11 May 2023 07:54:37 -0700 [thread overview]
Message-ID: <1683816877-10747-2-git-send-email-ssengar@linux.microsoft.com> (raw)
In-Reply-To: <1683816877-10747-1-git-send-email-ssengar@linux.microsoft.com>
MTRRs are not per-VTL and are controlled by VTL0, make sure it
is disabled for all other VTLs.
X86_MPPARSE scans low memory for MP tables, which is not required
for Hyper-V VTL platforms.
