LuCI status page for Airoha AN7581 SoC on OpenWrt. Covers CPU frequency control, NPU monitoring, and PPE flow offload.

• Live frequency bar with real-time polling
• Governor selection (ondemand, performance, powersave, etc.)
• Max frequency control via OPP table (500-1400 MHz)
• Direct PLL overclock up to 1600 MHz via devmem (bypasses cpufreq)
• Overclock detection -- bar turns orange with (OC) label when running above OPP max

• Firmware version (TLB format)
• NPU load status and device binding
• Clock speed and core count (8 RISC-V cores)
• Reserved memory regions with sizes

• Real-time PPE flow entries table (state, type, original/new flow, ethernet)
• Per-flow packet and byte counters
• Bound/unbound flow summary

• OpenWrt with LuCI on Airoha AN7581
• PPE debugfs enabled (/sys/kernel/debug/ppe/entries)
• devmem for overclock feature

• Governor and max frequency changes are not persistent across reboot
• Overclock writes PLL registers directly -- same method as ATF BL31 en7523_armpll_set()
• Frequencies above 1400 MHz may be unstable at stock voltage (~640 mV)
• OPP table supports 500-1400 MHz in 50 MHz steps (levels 0-18)
