Re: CPU load vs. Turbo mode

If your goal is to have constant oc why dont you set force turbo to 1?

Setting up threshold to near 0 is same as having oc all the time, atleast in openelec.

Re: CPU load vs. Turbo mode

If one sets the cpu_idle too low navigating the UI of XBMC will trigger the OC.
Which it is not a bad thing at all, having it running @ 300mhz idle and OC'ed when in use.

Is it stable @ 300 Mhz?

Re: CPU load vs. Turbo mode

Afaik the RPi only has two speeds, the 'non turbo' and the turbo.
When the trigger is reached it enters turbo mode, so having a low non turbo will kick turbo in with little effort.

Re: CPU load vs. Turbo mode

No, sleep 20 is to give the system time to set the value so that we can change it after. Without sleep 20 the custom value would be applied before the system default value (95) and replaced.
The 50 is the cpu load in % that triggers the OC (default 95).

Re: CPU load vs. Turbo mode

afaik it does NOT void the warranty but I could be wrong :) you're just forcing the OC to kick in 'sooner'.

Re: CPU load vs. Turbo mode

I have the script in

Code: Select all

/storage/.config/autostart.sh
You need to make it exec

Code: Select all

#!/bin/sh
(sleep 20
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold

Re: CPU load vs. Turbo mode

Yeah, i run the script (autostart.sh) at boot.
I'm currently using 50 up_threshold and it's working great.

AFAIK it's not, the RPi dynamic OC it's an On/Off thing.
There's only one OC value and that only kicks in when up_threshold is met (default 95).

Re: CPU load vs. Turbo mode

Well, I don't want the dynamic OC to kick in when the CPU is at 95%. I want it to jump from 700mhz to 900mhz when the CPU as a load of 50% or 60%. This makes the XBMC GUI a bit smoother and faster. Basically, I want the TRPi to be OC'ed when in use, unless isn't really needed, and to go back to defa...

CPU load vs. Turbo mode

Turbo mode only kicks in when arm usage is 100% AFAIK.

Is it possible to change this value?

It would be great if we could set this percentage manually.

TIA
