SubFunction [1] is a portion of the PCI device, a SF netdev has its own
dedicated queues(txq, rxq). A SF netdev supports E-Switch representation
offload similar to existing PF and VF representors. A SF shares PCI
level resources with other SFs and/or with its parent PCI function.
>From SmartNIC perspective, when PCI device is shared for multi-host,
representors for host controller and host PF is required.
This patch set introduces new representor types in addtion to existing
VF representor. Syntax:
[[c#]pf#]vf#: VF port representor/s from controller/pf
[[c#]pf#]sf#: SF port representor/s from controller/pf
#: VF representor - for backwards compatibility
"#" is number instance, list or range, valid examples:
1, [1,3,5], [0-3], [0,2-4,6]
For backward compatibility, this patch also introduces new netdev
capability to indicate the capability of supportting SF representor.
Version history:
RFC:
initial version [2]
V2:
- separate patch for represnetor infrastructure, controller, pf and
sf.
- replace representor ID macro with functions:
rte_eth_representor_id_encode()
rte_eth_representor_id_parse()
- new patch to allow devargs with same PCI BDF but different
representors.
- other minor code updates according to comments, thanks Andrew!
- update document
V3:
- improve probing of allowed devargs with same name.
- parse single word of kvargs as key.
- update kvargs test cases.
V4:
- split first representor refactor patch into
1: add representor type
2: refector representor list parsing
- push the patch supporting multi-devargs for same device.
V5:
- add comments for parsing functions
- update switch_representation.rst - Thanks Ajit
V6:
- split representor types into different patches, move to
rte_ethdev.h
- improvements of rte_eth_devargs_process_list() according to
Andrew's suggestion
- fixed PF probe failure for Intel i40e
- replace ethdev SF capability with rte_eth_representor_info_get()
- add new ethdev ops api to get representor info from PMD
- replace representor ID encode/decode with conversion from
representor info
- change ethdev representor iterator to use new ID encoding
V7:
- error on duplicated representor argument:
DBDF,representor=a,representor=b
- fix pf representor type parsing
- other small fixes suggested by Andrew.
V8:
- remove the "ignore" hint from pmd representor info
- changed representor_id type in representor info to u32
- rename rte_eth_representor_id_convert() to ..._get()
- other small fixes suggested by Andrew
