Subject: [dpdk-dev] [PATCH 01/27] eventdev: dlb upstream prerequisites
Date: Thu, 30 Jul 2020 14:49:48 -0500
Message-ID: <1596138614-17409-2-git-send-email-timothy.mcdaniel@intel.com> (raw)
In-Reply-To: <1596138614-17409-1-git-send-email-timothy.mcdaniel@intel.com>

From: "McDaniel, Timothy" <timothy.mcdaniel@intel.com>

The DLB hardware does not conform exactly to the eventdev interface.
1) It has a limit on the number of queues that may be linked to a port.
2) Some ports a further restricted to a maximum of 1 linked queue.
3) It does not (currently) have the ability to carry the flow_id as part
of the event (QE) payload.

Due to the above, we would like to propose the following enhancements.

1) Add new fields to the rte_event_dev_info struct. These fields allow
the device to advertize its capabilities so that applications can take
the appropriate actions based on those capabilities.

    struct rte_event_dev_info {
	uint32_t max_event_port_links;
	/**< Maximum number of queues that can be linked to a single event
	 * port by this device.
	 */

	uint8_t max_single_link_event_port_queue_pairs;
	/**< Maximum number of event ports and queues that are optimized for
	 * (and only capable of) single-link configurations supported by this
	 * device. These ports and queues are not accounted for in
	 * max_event_ports or max_event_queues.
	 */
    }

2) Add a new field to the rte_event_dev_config struct. This field allows
the application to specify how many of its ports are limited to a single
link, or will be used in single link mode.

    /** Event device configuration structure */
    struct rte_event_dev_config {
	uint8_t nb_single_link_event_port_queues;
	/**< Number of event ports and queues that will be singly-linked to
	 * each other. These are a subset of the overall event ports and
	 * queues; this value cannot exceed *nb_event_ports* or
	 * *nb_event_queues*. If the device has ports and queues that are
	 * optimized for single-link usage, this field is a hint for how many
	 * to allocate; otherwise, regular event ports and queues can be used.
	 */
    }

3) Replace the dedicated implicit_release_disabled field with a bit field
of explicit port capabilities. The implicit_release_disable functionality
is assigned to one bit, and a port-is-single-link-only  attribute is
assigned to other, with the remaining bits available for future assignment.

	* Event port configuration bitmap flags */
	#define RTE_EVENT_PORT_CFG_DISABLE_IMPL_REL    (1ULL << 0)
	/**< Configure the port not to release outstanding events in
	 * rte_event_dev_dequeue_burst(). If set, all events received through
	 * the port must be explicitly released with RTE_EVENT_OP_RELEASE or
	 * RTE_EVENT_OP_FORWARD. Must be unset if the device is not
	 * RTE_EVENT_DEV_CAP_IMPLICIT_RELEASE_DISABLE capable.
	 */
	#define RTE_EVENT_PORT_CFG_SINGLE_LINK         (1ULL << 1)

	/**< This event port links only to a single event queue.
	 *
	 *  @see rte_event_port_setup(), rte_event_port_link()
	 */

	#define RTE_EVENT_PORT_ATTR_IMPLICIT_RELEASE_DISABLE 3
	/**
	 * The implicit release disable attribute of the port
	 */

	struct rte_event_port_conf {
		uint32_t event_port_cfg; /**< Port cfg flags(EVENT_PORT_CFG_) */
	}

4) Add UMWAIT/UMONITOR bit to rte_cpuflags

5) Added a new API that is useful for probing PCI devices.

	/**
	 * @internal
	 * Wrapper for use by pci drivers as a .probe function to attach to a event
	 * interface.  Same as rte_event_pmd_pci_probe, except caller can specify
	 * the name.
	 */
	static inline int
	rte_event_pmd_pci_probe_named(struct rte_pci_driver *pci_drv,
				    struct rte_pci_device *pci_dev,
				    size_t private_data_size,
				    eventdev_pmd_pci_callback_t devinit,
				    const char *name);
