ippStsRepetitiveSrcData
The numeric result becomes useful only when tied to the exact operation and object state. The data-compression or codebook-related primitive detected insufficient variation in the source data for the requested calculation.
First returning layer
Intel IPP assigns meaning to the sign of IppStatus: negative is error, zero is clean completion, and positive is warning with potentially usable output. Output validation is therefore inseparable from status handling.
Intel IPP uses negative values for errors, zero for no warning/error, and positive values for warnings that can accompany completed output. Do not treat every nonzero status as an aborted operation. Keep the numeric value, declared return type, and first returning operation together with This result; the same integer can belong to a different status namespace in another API.
Evidence map
| Capture | Diagnostic value |
|---|---|
| Function, source length, distinct-value/vector count, variance, block size, requested model/codebook, and status. | Identifies the concrete object and operation associated with Intel IPP source data too repetitive. |
| IppStatus sign and value interpreted using the same IPP headers as the linked library. | Separates argument or lifecycle state from the provider beneath Intel IPP source data too repetitive. |
| Output-buffer state and checksum before and after the call. | Creates a stable before-and-after comparison. |
| Reference result or invariant appropriate to the primitive domain. | Shows whether Intel IPP source data too repetitive for the requested operation is the first result or a translated summary. |
For This result preserve output-buffer state and checksum before and after the call for this condition for the requested operation case before reinstalling, rebooting, clearing state, or substituting another device or provider. A success observed only after such a change is useful comparison data for It but it does not identify the original cause.
Change one condition at a time
- Run the same operation on a controlled diverse source of equal size. Treat a changed result as a new boundary rather than automatic resolution.
- Run one boundary input and one known-good control without changing dispatch/library version. Repeat the original supported operation so the check remains tied to the same API boundary.
- Check the status immediately; IPP does not preserve a global last-status value. Keep unrelated inputs fixed so the changed result remains attributable to the tested variable.
Decision points
| Observed comparison | Next conclusion to test |
|---|---|
| The first control changes the result | Concentrate on the variable isolated by this check: Run the same operation on a controlled diverse source of equal size. |
| The second comparison for this condition for the requested operation reproduces the same first status | Preserve lower-layer provider, driver, service, or runtime evidence before editing application data. The second controlled check was: Run one boundary input and one known-good control without changing dispatch/library version. |
| A different status replaces this condition for the requested operation after the bounded change | The operation moved to another boundary after the third controlled check. That check was: Check the status immediately; IPP does not preserve a global last-status value. Retain both results and interpret the replacement through its own API contract. |
Repair and regression test
Targeted correction. Short-circuit constant/repetitive blocks or choose parameters appropriate to the observed diversity. For This result modify only the object, argument, policy, provider, or lifecycle state identified by the collected evidence.
Acceptance criterion. Constant and diverse inputs follow documented paths and repetitive input no longer creates invalid model state. Re-run the original operation that produced This result under its original identity and supported configuration, then keep one negative control that still produces the expected neighboring outcome.
