cupvaError_t err

CUPVA_ERROR_NONE while the current Context is usable, otherwise the first error that invalidated it.

uint32_t stream

The Stream the failing work was submitted on, counted in order of creation on this Context, from 1.

Zero when the failure cannot be attributed to a Stream, which happens when the work was submitted by cuPVA itself rather than through a Stream.

uint32_t submissionsSinceError

The number of CupvaStreamSubmit() calls made on that Stream between the submission that triggered the asynchronous error and the first one to fail with CUPVA_INVALID_CONTEXT.

Zero means the most recent submission on that Stream was the cause. Bounded by the number of submissions the application can have in flight at once. Set to CUPVA_SUBMISSION_UNKNOWN when the failing submission could not be located.

uint32_t command

The command within that submission, in the order the application passed them to submit, from 0.

Set to CUPVA_COMMAND_UNKNOWN when the command range could not be resolved.

char const *streamName

The name registered for that Stream through CupvaStreamSetName, or NULL when the Stream was never named.

char const *errorMsg

Human readable diagnostic.

Format is not stable between releases or platforms.
