Subject: [dpdk-dev] [PATCH 1/2] config: add Graviton2(arm64) meson configuration
Date: Tue, 8 Sep 2020 18:11:08 -0700 [thread overview]
Message-ID: <20200909011109.2048-2-vcchunga@amazon.com> (raw)
In-Reply-To: <20200909011109.2048-1-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/
