Subject: [dpdk-dev] [PATCH v5 1/3] drivers/qat: improve handling of multi process
Date: Tue, 7 Jul 2020 17:02:37 +0200 [thread overview]
Message-ID: <20200707150239.13400-2-arkadiuszx.kusztal@intel.com> (raw)
In-Reply-To: <20200707150239.13400-1-arkadiuszx.kusztal@intel.com>
This patch refactors qat data into structures which are local to the process and
structures which are intended to be shared by primary and secondary processes.
This enables qat devices to be used by multi process applications.
