Subject: [edk2-platforms] [PATCH v3 2/3] Platform/ARM/SgiPkg: Add HMAT ACPI table for RdN1EdgeX2
Date: Wed, 17 Feb 2021 16:31:56 +0530 [thread overview]
Message-ID: <1613559717-30499-3-git-send-email-vijayenthiran.subramaniam@arm.com> (raw)
In-Reply-To: <1613559717-30499-1-git-send-email-vijayenthiran.subramaniam@arm.com>
Add HMAT table support for RD-N1-Edge dual-chip platform. The latencies
mentioned in the table are hypothetical values and represents typical
latency between two chips. These values are applicable only for
RD-N1-Edge dual-chip fixed virtual and should not be reused for other
platforms.
