Subject: [PATCH 61/61] power: replace use of rte_memcpy
Date: Wed, 19 Aug 2026 22:12:51 -0700 [thread overview]
Message-ID: <20260820052251.1453273-62-stephen@networkplumber.org> (raw)
In-Reply-To: <20260820052251.1453273-1-stephen@networkplumber.org>
All the uses of rte_memcpy() in the power drivers are in the
frequency list query API, which is control path only. Regular
memcpy() has no performance disadvantage there and gets more
compile time checking of the arguments.
