| Microbenchmark | v3.05 (cycles) | v3.06 + CFI (cycles) | Overhead |
|----------------|----------------|----------------------|-----------|
| Null syscall (getpid) | 110 | 117 | 6.4% |
| read (4 KiB) | 430 | 451 | 4.9% |
| kld6_ipc_send (64 B) | 890 | 940 | 5.6% |
Overhead considered acceptable for security-sensitive deployments; optional boot flag nosyscfi disables CFI for performance-optimized builds.
Prerequisites:
Step-by-Step Procedure:
Monitor progress: The STATUS LED will flash Green-Orange-Green during the write. Do not cycle power.
Automatic reboot: After approximately 4 minutes, the unit will reboot twice. First boot loads the new bootloader; second boot loads the kernel.
Post-update validation: Wait for the RUN LED to be steady green.
Expected Downstream Impact: The I/O bus will be disconnected for exactly 210 seconds. Ensure your process can tolerate this interruption.
The previous stable version, V3.04, suffered from three systemic issues identified during Q4 2024 stress tests:
Version 3.06 is a culmination of four months of beta testing (V3.05 was scrapped due to SPI bus regressions). The primary goal of V3.06 is to extend the Mean Time Between Failures (MTBF) from 150,000 hours to 200,000 hours under high thermal load.
