The top operating frequencies for both big and little cores appear to be missing:
- firefly@firefly:~$ cat /sys/devices/system/cpu/cpu4/cpufreq/scaling_available_frequencies
- 408000 600000 816000 1008000 1200000 1416000 1608000 1800000
- firefly@firefly:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
- 408000 600000 816000 1008000 1200000 1416000
Copy the code
The device tree indicates the support here:
https://gitlab.com/TeeFirefly/li ... 9-opp.dtsi#L133-137
- opp@1992000000 {
- opp-hz = /bits/ 64 <1992000000>;
- opp-microvolt = <1225000>;
- clock-latency-ns = <40000>;
- };
Copy the code
https://gitlab.com/TeeFirefly/li ... 399-opp.dtsi#L81-85
- opp@1512000000 {
- opp-hz = /bits/ 64 <1512000000>;
- opp-microvolt = <1125000>;
- clock-latency-ns = <40000>;
- };
Copy the code
Are these frequencies omitted because they are unstable or due to an oversight? |
