Subject: [dpdk-dev] [PATCH v11 3/5] common/qat: use WC store to update queue tail registers
Date: Wed, 26 Aug 2020 10:55:50 +0100 [thread overview]
Message-ID: <20200826095552.82525-4-radu.nicolau@intel.com> (raw)
In-Reply-To: <20200826095552.82525-1-radu.nicolau@intel.com>
Performance improvement: use a write combining store
instead of a regular mmio write to update queue tail
registers.
