Subject: [dpdk-dev] [PATCH v2 11/20] net/sfc: add NUMA-aware registry of service logical cores
Date: Fri,  4 Jun 2021 17:24:05 +0300
Message-ID: <20210604142414.283611-12-andrew.rybchenko@oktetlabs.ru> (raw)
In-Reply-To: <20210604142414.283611-1-andrew.rybchenko@oktetlabs.ru>

The driver requires service cores for housekeeping. Share these
cores for many adapters and various purposes to avoid extra CPU
overhead.

Since housekeeping services will talk to NIC, it should be possible
to choose logical core on matching NUMA node.
