v3:
(Note: v3 work is based on deprecation notice [1], It's for 17.11)
* Changed _version.map from 17.08 to 17.11.
* build fixes reported by stv_sys.
* Patchset rebased on upstream commit: da94a999.
v2:
In order to support octeontx HW mempool manager, the common mempool layer must
meet below condition.
- Object start address should be block size (total elem size) aligned.
- Object must have the physically contiguous address within the pool.
And right now mempool doesn't support both.
Patchset adds infrastrucure to support both condition in a _generic_ way.
Proposed solution won't effect existing mempool drivers or its functionality.
Summary:
Introducing capability flag. Now mempool drivers can advertise their
capabilities to common mempool layer(at the pool creation time).
Handlers are introduced in order to support capability flag.
Flags:
* MEMPOOL_F_CAPA_PHYS_CONTIG - If flag is set then Detect whether the object
has the physically contiguous address with in a hugepage.
* MEMPOOL_F_POOL_BLK_SZ_ALIGNED - If flag is set then make sure that object
addresses are block size aligned.
API:
Two handles are introduced:
* rte_mempool_ops_get_capability - advertise mempool manager capability.
* rte_mempool_ops_update_range - Update start and end address range to
HW mempool manager.
v2 --> v1 :
* [01/06] Per deprecation notice [1], Changed rte_mempool 'flag'
data type from int to unsigned int and removed flag param
from _xmem_size/usage api.
* [02/06] Incorporated review feedback from v1 [2] (Suggested by Olivier)
* [03/06] Renamed flag to MEMPOOL_F_CAPA_PHYS_CONTIG
and comment reworded. (Suggested by Olivier per v1 [3])
* [04/06] added new mempool arg in xmem_size/usage. (Suggested by Olivier)
* [05/06] patch description changed.
- Removed elseif brakcet mix
- removed sanity check for alignment
- removed extra var delta
- Removed __rte_unused from xmem_usage/size and added _BLK_SZ_ALIGN
check.
(Suggeted by Olivier per v1[4])
* [06/06] Added RTE_FUNC_PTR_OR_RET in rte_mempool_ops_update_ops.
Checkpatch status:
* WARNING: line over 80 characters
Noticed for debug messages.
Work history:
For v1, refer [5].
