Subject: [dpdk-dev] [PATCH v5 05/16] dma/idxd: create dmadev instances on pci probe
Date: Fri, 17 Sep 2021 15:24:26 +0000	[thread overview]
Message-ID: <20210917152437.3270330-6-kevin.laatz@intel.com> (raw)
In-Reply-To: <20210917152437.3270330-1-kevin.laatz@intel.com>

When a suitable device is found during the PCI probe, create a dmadev
instance for each HW queue. HW definitions required are also included.
