Overclocking potential
- CPU: Not feasible from userspace. The
cpufreq-dt driver only accepts frequencies present in the device tree OPP table (600 / 1008 MHz). Writing a higher value to scaling_max_freq is silently clamped. A kernel or DTB patch would be required, with significant risk given the unknown voltage regulator configuration.
- GPU: No clock frequency controls are exposed. The Mali driver has no debugfs mount and no sysfs clock nodes.
