Subject: [PATCH v5 1/5] drivers/raw: introduce AFU raw device driver
Date: Fri, 27 May 2022 01:37:00 -0400	[thread overview]
Message-ID: <1653629824-4535-2-git-send-email-wei.huang@intel.com> (raw)
In-Reply-To: <1653629824-4535-1-git-send-email-wei.huang@intel.com>

Add multi-function AFU raw device driver to manage various AFU
(Acceleration Function Unit) in FPGA.
This driver implements common AFU raw device interfaces and
exposes them to application as standard raw device APIs.
Normal application can operate specified AFU as below,
1. call rte_rawdev_pmd_get_named_dev() to find AFU raw device.
2. call rte_rawdev_configure() to initialize AFU raw device.
3. call rte_rawdev_selftest() to test function of AFU.
