Re: Radxa Orion O6

About CPU frequency,

machdep.cpufreq is available, but it seems odd:

# sysctl machdep.cpufreq
machdep.cpufreq.cpu0.target = 5898
machdep.cpufreq.cpu0.current = 5898
machdep.cpufreq.cpu0.available = 8192 2621

# openssl speed aes-256-cbc 2> /dev/null | tail -1
aes-256-cbc     738556.94k   937067.21k   996297.31k  1007614.30k 
1009975.62k  1010147.08k

# sysctl -w machdep.cpufreq.cpu0.target=2621
machdep.cpufreq.cpu0.target: 5898 -> 2621
# openssl speed aes-256-cbc 2> /dev/null | tail -1
aes-256-cbc     328715.25k   416477.55k   442692.12k   446807.99k 
449967.45k   448774.63k

# sysctl -w machdep.cpufreq.cpu0.target=8192
machdep.cpufreq.cpu0.target: 2621 -> 8192
# openssl speed aes-256-cbc 2> /dev/null | tail -1
aes-256-cbc    1026106.38k  1301582.42k  1383831.73k  1399466.44k 
1400752.81k  1403052.82k

it seems
2621: 800MHz (2621*10000/32768MHz)
5898: 1.8GHz (5898*10000/32768MHz)
8192: 2.5GHz (8192*10000/32768MHz)


Below is information about cpufreq for Linux (ACPI).
