Subject: [dpdk-dev] [PATCH 02/10] mempool/octeontx: probe timvf PCIe devices
Date: Sat, 17 Feb 2018 03:06:52 +0530 [thread overview]
Message-ID: <20180216213700.3415-3-pbhagavatula@caviumnetworks.com> (raw)
In-Reply-To: <20180216213700.3415-1-pbhagavatula@caviumnetworks.com>
On Octeontx HW, each event timer device is enumerated as separate SRIOV VF
PCIe device.
In order to expose as a event timer device:
On PCIe probe, the driver stores the information associated with the
PCIe device and later when appliacation requests for a event timer device
through `rte_event_timer_adapter_create` the driver infrastructure creates
the timer adapter with earlier probed PCIe VF devices.
