Hello,
Is it possible to set the CPU speed on the ODROID XU4 (Exynos
5422)? The sysctl command doesn’t seem to list anything and I
haven’t found anything via Google. I’ve tried both kernels running
9.0_STABLE and HEAD (9.99.71). If not, what speed are the CPU
cores running at? (I'm also curious why 5 cores show up instead of
8, but that can wait).
These lines from dmesg seem to be relevant:
[ 1.493147] cpufreqdt0: autoconfiguration error: couldn't
acquire cpu-supply
[ 1.493147] cpufreqdt1: autoconfiguration error: couldn't
acquire cpu-supply
[ 1.503152] cpufreqdt2: autoconfiguration error: couldn't
acquire clock
[ 1.503152] cpufreqdt3: autoconfiguration error: couldn't
acquire clock
[ 1.513150] cpufreqdt4: autoconfiguration error: couldn't
acquire clock
Thanks,
Jason M.
