Issues running on AMD x64 SoC #1

Open Strykar opened 5 years ago

Strykar commented 5 years ago

I made OpenWRT packages for heatppm and unidled and I'm not a programmer and unsure what processor features these depend on. I've cross-compiled both binaries, however:

root@apu:~# heatppm -t /sys/class/hwmon/hwmon1/temp1_input
sched_setscheduler: Function not implemented

If it matters, the system's running irqbalance without any options. What's missing here, as Musl (which openwrt uses) has sched_setscheduler?

I just had a quick look and it seems that musl dosn't implement sched_setscheduler properly. Please see https://github.com/MusicPlayerDaemon/MPD/issues/218 for a discussion and a workaround. Unfortunately due to ongoing health issues I can't work on the code for the forseeable future.
