Sec S3c2443x Test B D Driver -

The tool prints timing results and, on failure, dumps the kernel log ( dmesg ) with the error code.

The driver’s DMA engine reaches near‑theoretical bandwidth of the S3c2443x’s AXI‑Lite bus, while the CE maintains sub‑microsecond per‑kilobyte latency for AES‑256. Sec S3c2443x Test B D Driver
