Subject: [dpdk-dev] [PATCH v3 14/25] raw/ioat: create rawdev instances on idxd PCI probe
Date: Fri, 25 Sep 2020 12:08:59 +0100
Message-ID: <20200925110910.284098-15-bruce.richardson@intel.com> (raw)
In-Reply-To: <20200925110910.284098-1-bruce.richardson@intel.com>

When a matching device is found via PCI probe create a rawdev instance for
each queue on the hardware. Use empty self-test function for these devices
so that the overall rawdev_autotest does not report failures.
