Subject: [dpdk-dev] [PATCH v2 1/1] build: add Graviton2(arm64) meson configuration
Date: Tue, 27 Oct 2020 13:17:33 -0700
Message-ID: <20201027201733.14206-2-vcchunga@amazon.com> (raw)
In-Reply-To: <20201027201733.14206-1-vcchunga@amazon.com>

Add meson build configuration for Graviton2 platform
with 64-bit Arm Neoverse N1 cores. This patch makes the
following changes to generic Neoverse N1 config:

1. increase lcore limit to 64
2. increase memory support to 1TB
3. remove +crc from -march as that is default when setting armv8.2

For more information about Graviton2 platform, refer to:
https://aws.amazon.com/ec2/graviton/
