Subject: [edk2-platforms][PATCH V3 03/14] Platform/Sgi: ACPI PPTT table for SGI-575 platform
Date: Tue, 11 May 2021 01:36:04 +0530	[thread overview]
Message-ID: <20210510200615.26879-4-pranav.madhu@arm.com> (raw)
In-Reply-To: <20210510200615.26879-1-pranav.madhu@arm.com>

The SGI-575 platform includes two clusters with four single-thread CPUs.
Each of the CPUs include 64KB L1 Data cache, 64KB L1 Instruction cache
and 512KB L2 cache. Each cluster includes a 2MB L3 cache. Add PPTT table
for SGI-575 platform with this information.
