Subject: [dpdk-dev] [PATCH v2 0/2] Dynamically configure mempool handle
Date: Thu, 20 Jul 2017 12:36:11 +0530	[thread overview]
Message-ID: <20170720070613.18211-1-santosh.shukla@caviumnetworks.com> (raw)
In-Reply-To: <20170601080559.10684-1-santosh.shukla@caviumnetworks.com>

DPDK has support for hw and sw mempool. Those mempool
can work optimal for specific PMD's. 
Example:
sw ring based PMD for Intel NICs.
HW mempool manager dpaa2 for dpaa2 PMD.
HW mempool manager fpa for octeontx PMD.

There could be a use-case where different vendor NIC's used
on the same platform and User like to configure mempool in such a way that
each of those NIC's should use their preferred mempool(For performance reasons).

Current mempool infrastrucure don't support such use-case.

This patchset tries to address that problem in 2 steps:

0) Allowing user to dynamically configure mempool handle by  
passing pool handle as eal arg to `--mbuf-pool-ops=<pool-handle>`.

1) Allowing PMD's to advertise their preferred pool to an application.
>From an application point of view:
- The application must ask PMD about their preferred pool.
- PMD to respond back with preferred pool otherwise
  CONFIG_RTE_MEMPOOL_DEFAULT_OPS will be used for that PMD.

* Application programming sequencing would be
    char pref_mempool[RTE_MEMPOOL_OPS_NAMESIZE];
    rte_eth_dev_get_preferred_pool_ops(ethdev_port_id, pref_mempool /* out */);
    rte_mempool_create_empty();
    rte_mempool_set_ops_byname( , pref_memppol, );
    rte_mempool_populate_default();

Change History:
v1 --> v2:
 - Renamed rte_eal_get_mempool_name to rte_eal_mbuf_default_mempool_ops().
	(suggested by Olivier)
 - Renamed _get_preferred_pool to _get_preferred_pool_ops().
 - Updated API description and changes return val from -EINVAL to -ENOTSUP.
   (Suggested by Olivier)
* Specific details on v1-->v2 change summary described in each patch.

Checkpatch status:
- None.

Work History:
* Refer [1] for v1.

Thanks.
