Subject: [dpdk-dev] [PATCH v1 1/6] build: increase default of max lcores to 512
Date: Thu, 9 Sep 2021 14:45:06 +0100 [thread overview]
Message-ID: <20210909134511.18871-2-david.hunt@intel.com> (raw)
In-Reply-To: <20210909134511.18871-1-david.hunt@intel.com>
Modern processors are coming with an ever increasing number of cores,
and 128 does not seem like a sensible max limit any more, especially
when you consider multi-socket systems with Hyper-Threading enabled.
This patch increases max_lcores default from 128 to 512.
