Patches rebased on upstream tip / commit id:5dce9fcdb2
v4:
- Includes v3 review coment changes.
Patches rebased on 06791a4bce: ethdev: get the supported pools for a port
v3:
- Rebased on top of v17.11-rc0
- Updated version.map entry to v17.11.
v2:
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-name=<pool-handle>`.
1) Allowing PMD's to advertise their pool capability to an application.
>From an application point of view:
- The application must ask to PMD about supported pools.
- PMD will advertise his pool capability in priority order
'0' - Best match mempool ops for _that_ port (highest priority)
'1' - PMD support this mempool ops.
- Based on those i/p from PMD, application to chose pool-hdl and
do pool create.
Change History:
