Detailed Description

Driver API for PLDM OEM command handlers.

A driver that registers with compatible "tenstorrent,pldm-oem-handler" implements this API so that the PLDM responder and base layers can route OEM-type messages without a compile-time dependency on the concrete handler.

Field Documentation

build_response

int(* pldm_oem_handler_driver_api::build_response) (const struct device *dev, const struct pldm_header_info *req_hdr, const struct pldm_msg *req_msg, size_t req_payload_len, struct pldm_msg *resp_msg, size_t *resp_pldm_len)

Build a PLDM response for an OEM-type request.

Parameters

dev	Driver instance.
req_hdr	Decoded request header.
req_msg	Raw request message (including header).
req_payload_len	Payload length (bytes after the PLDM header).
resp_msg	Output buffer for the response.
resp_pldm_len	Set to the response length on success.

Returns

0 on success, negative errno on failure.

get_commands

const bitfield8_t *(* pldm_oem_handler_driver_api::get_commands) (const struct device *dev)

Return the supported OEM command bitmap (32-byte array of bitfield8_t).

Parameters

dev	Driver instance.

Returns

Pointer to the commands bitmap, or NULL on error.

get_versions

const ver32_t *(* pldm_oem_handler_driver_api::get_versions) (const struct device *dev, size_t *versions_size)

Return the supported OEM version table.

Parameters

dev	Driver instance.
versions_size	Set to the byte length of the returned array.

Returns

Pointer to the version array, or NULL on error.
