Meta data known as scratch data can be used to match or modify within pipes. Meta data can be set with value in previous pipes and match in later pipes. User can customize meta data structure as long as overall size doens't exceed limit. To match meta data, mask must be specified when creating pipe. Struct must be aligned to 32 bits. No initial value for Meta data, must match after setting value.

Variables

struct doca_jobdoca_sha_job::base [inherited]

Opaque structure.

uint64_t doca_sha_job::flags [inherited]

SHA job flags. For the last segment of a doca_sha_partial_job, use DOCA_SHA_JOB_FLAGS_SHA_PARTIAL_FINAL. Otherwise, use DOCA_SHA_JOB_FLAGS_NONE.

doca_buf * doca_sha_job::req_buf [inherited]

User request. SHA engine accessible buffer pointed to the user input data. The req_buf can be a linked_list doca_buf, so that a chained multiple bufs can be used as valid request.

doca_buf * doca_sha_job::resp_buf [inherited]

User response. The response byte count can be decided by DOCA_SHAXXX_BYTE_COUNT macro. The chained doca_buf is descouraged to be used as a response. Although resp_buf can be a linked_list doca_buf, no submission failure, but only the head element of the chained buf is used for now, because the SHA output is no more than 64bytes.

[engine]

DOCA SHA_PARTIAL job definition. -- "struct doca_sha_partial_job" is used for stateful SHA calculation. -- Its typical usage for a job composed of 3 segments is: -- get a session handle: doca_sha_partial_session *session; doca_sha_partial_session_create(ctx, workq, &session); -- construct the 1st job: struct doca_sha_partial_job job = { .sha_job.base.type = DOCA_SHA_JOB_SHA1_PARTIAL, .sha_job.req_buf = user_req_buf_of_1st_segment, .sha_job.resp_buf = user_resp_buf, .sha_job.flags = DOCA_SHA_JOB_FLAGS_NONE, .session = session, }; -- submit 1st segment: doca_workq_submit(workq, &job.sha_job.base); -- retrieve 1st event: doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); The purpose of this call is to make sure the 1st_segment processing is finished before we can continue to send the next segment, because it is necessary to sequentially process all segment for generating correct SHA result. And the "user_resp_buf" at this moment contains garbage values. -- after the DOCA_SUCCESS event of the 1st segment is received, we can continue to submit 2nd segment: -- construct the 2nd job: struct doca_sha_partial_job job = { .sha_job.base.type = DOCA_SHA_JOB_SHA1_PARTIAL, .sha_job.req_buf = user_req_buf_of_2nd_segment, .sha_job.resp_buf = user_resp_buf, .sha_job.flags = DOCA_SHA_JOB_FLAGS_NONE, .session = session, }; -- submit 2nd segment: doca_workq_submit(workq, &job.sha_job.base); -- retrieve 2nd event: doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); The purpose of this call is also to make sure the 2nd_segment processing is finished. And the "user_resp_buf" at this moment still contains garbage values. -- after the DOCA_SUCCESS event of the 2nd segment is received, we can continue to submit 3rd/final segment: -- construct the 3rd job: struct doca_sha_partial_job job = { .sha_job.base.type = DOCA_SHA_JOB_SHA1_PARTIAL, .sha_job.req_buf = user_req_buf_of_3rd_segment, .sha_job.resp_buf = user_resp_buf, .sha_job.flags = DOCA_SHA_JOB_FLAGS_SHA_PARTIAL_FINAL, .session = session, }; -- submit 3rd segment: doca_workq_submit(workq, &job.sha_job.base); -- retrieve 3rd event: doca_workq_progress_retrieve(workq, &event, DOCA_WORKQ_RETRIEVE_FLAGS_NONE); -- After the DOCA_SUCCESS event of the 3rd segment is received, the whole job processing is done. We can get the expected SHA result from "user_resp_buf". -- release session: doca_sha_partial_session_destroy(ctx, workq, session); -- During the whole process, please make sure to use the same "session" handle. -- And for the last segment, the "DOCA_SHA_JOB_FLAGS_SHA_PARTIAL_FINAL" flag must be set.

-- For doca_workq_submit() return code: -- DOCA_SUCCESS: -- The job is submitted successfully. It also means: this submitted source data cannot be freely manipulated until its response is received. -- DOCA_ERROR_INVALID_VALUE: -- Some of the job attribute members use illegal value. for example, response buffer length is < 20bytes for SHA1; request buffer length == 0, and the job type attribute is not supported. -- DOCA_ERROR_NO_MEMORY: -- The job resouce is exhausted for now, we need to call progress_retrieve() first to receive response and free job resource, then call job_submit() to try again to submit the same job. -- DOCA_ERROR_BAD_STATE: -- sha_ctx is corrupted now, need reset.

-- For doca_workq_progress_retrieve() return code: -- DOCA_SUCCESS: -- we get a response from SHA engine. user can utilise doca_job's user_data field to setup special data to correlate the returned event and the corresponding job. -- DOCA_ERROR_AGAIN: -- In order to get a response, we need to call progress_retrieve() again. -- DOCA_ERROR_IO_FAILED: -- abnormal occurs in the SHA engine hardware queue, sha_ctx and workq need to be re-initialized. -- DOCA_ERROR_INVALID_VALUE: -- received invalid input.

Note: -- sha_partial_job session requirement: -- make sure the same doca_sha_partial_session used for all segments of a whole job. -- before 1st segment submission, call doca_sha_partial_session_create() to grab a session handle. -- from the 1st to the last segment submission, always reuse the same session handle. -- after the last segment processing, to prevent a session resource leak, the user must explicitly call doca_sha_partial_session_destroy() to release this session handle. -- The doca_sha_partial_session_destroy() is provided to let user to free session handle at his will. -- If a session handle is released before the whole stateful SHA is finished, or if different handles are used for a stateful SHA, the job submission may fail due to job validity check failure; even the job submission successes, and the engine is not stalled, a wrong SHA result is expected. -- The "session" resource is limited, it is user's responsibility to make sure all allocated "session" handles are released. -- If "DOCA_SHA_JOB_FLAGS_SHA_PARTIAL_FINAL" is not properly set, the engine will not be stalled, but a wrong SHA result is expected.

-- sha_partial_job segment length requirement: -- only the last segment allows seg-byte-count != multiple-of-64 for sha1 and sha256. For example, for the above example code, the 1st and 2nd segment byte length must be multiple of 64. -- only the last segment allows seg-byte-count != multiple-of-128 for sha512. -- If the above requirement is not met, job_submission will fail.
