cpufreq-userspace-scaler's Issues

errors on boot, but OK when manually ran or executed a second time.

I have this script running as root as a scheduled task, user-defined script at boot-up of /usr/local/bin/scaler.sh &

I have it configured to send notification details by email.

When It runs at boot-up, I see
Current Status:0 (Normal) Standard output/error:/usr/local/bin/scaler.sh: line61:echo:write error:invalid argument.

If I go to that same scheduled job post-boot and right-click run, it runs properly.
Current Status:0 (Normal) Standard output/error:

maybe something is not quite ready yet at boot?
ps this cpu was recently changed a few times hex to quad to another hex core cpu, in case that matters.

DSM 7, cpu freq back to max every some time

Hi, I'm installing xpenology dsm 7 in my old amd athlon ii x3, noticing that cpu always at full speed (3ghz), and then i found this script. I try to install it..it working for some time, buat after that cpu back to max speed..can you tell me what I missed?.. thx

Getting wrong temp1_max resulting CPU to stay at Coolfreq

Hi there im attaching a screenshot to explain the script behaviour.

Until the first red arrow the script isn't running on the DS918+ so the default CPU freq is 1501
After the first red arrow and the Script is running but as the temp1_max is 105 the script using cut -c 1-2 is thinking that the temp1_max is 10 degrees so it is running always in Coolfreq =1300
After the second red arrow i modified and rerun the script using cut -c 1-3 for the temp1_max resulting in proper exucution of the code.

Kind regards.

Incorrect Processor Count for Xeon E3-1220L V2 (2C4T)

Hi, my CPU has 2 cores and 4 threads, running on a HP Microserver Gen8.

I used the dsm-7.1 branch, as i’m running DSM 7.1, booted with TCRP, with profile/config synology_broadwellnk_3622xs+.

I noticed that the script relies on grep cores /proc/cpuinfo | sort -u | awk '{ print $4 - 1 }' to acquire 0-based core count. However, the /proc/cpuinfo on my machine is showing 2 cores.

So here are my thoughts:

would it be better to key off the processor field, and just wc -l to get the core count? (grep processor /proc/cpuinfo | wc -l)
would it be better to key off the driver under /sys/devices/system/cpu/ and count the cpu[0-9]+ dirs? ( [ -d /sys/devices/system/cpu ] && ls /sys/devices/system/cpu | grep 'cpu[0-9][0-9]*$' | wc -l )
key off the /sys/devices/system/cpu/online to count the number of online (logical) processors? (although i cannot think of why one’d want to offline/disable cores/threads)

Those are just based off my inspection on my system. I’m not sure how universal are those driver files or fashion, when it comes to compatibility across different kernel version. (Mine’s still on 4.4)
