Hello, this is my first post and I'm spanish, sorry for my bad English.
I have an Archos G9 101 turbo 512 Mb RAM, and I flashed the surdu_petru Root & Deodex - Archos Firmware 4.0.28.
And my question is: Is the second core enable?, if not, how can I enable it?
Thanks a lot for your work.
Settings -> Developer -> Show hardware monitoring.
There's a lot of useful info.

I don't know if is this:
CPU's Online: sometimes 0 and sometimes 0-1
What does it mean?, is the second core enable?, if not, how can I enable it?
0 is the first core, 1 is second.
Your second core auto-disable when it is no used, and auto-enable when there's a need in it.

Thank's a lot for your answer.
Sorry, but I have not fully understood.
Then, do I have the two cores active or not?

Yes and no. Under load, like gaming, it is enabled. When there is no load, second core is disabled.

Does anyone know any good apps to check cpu usage that is known to be accurate, I have installed system panel and system tuner pro, both show all 4 core usage with on and sleep if cpu is not in use, the problem is all core 0,1,2,3.
both display different core in sleep mode at at the same time, example at the same time system panel shows core 1 and 2 in sleep mode, while system tuner pro shows core 1 and 3 in sleep mode, or just core 0 running and the other 3 sleeping.
so how do we know which is accurate and are these apps really that accurate.
thanks in advance.:victory:
CPU Spy
Check CPU SPY... Accurate and does not use any resources
anything to check all 4 core.
thanks

Use extweaks since you are using siyah. Open extweaks > press "CPU" tab if you are not on it by default > Hotplug mode > set to "Second core always-off".

May I ask why would you want to shut down second core?
If not for the battery or performance why then just doesn't make any sense!
Sent from my GT-I9100
try this
echo "off" > /sys/devices/virtual/misc/second_core/hotplug_on
echo "off" > /sys/devices/virtual/misc/second_core/second_core_on

Read ephraim033's post.
See title. I remember someone talking about it. Also, I remember seeing it the market but don't remember how I found it and can't duplicate the search.

well ro be honest with you. the second core is always enabled until the phone goes into sleep. from sleep mode, the kernel disables the second core. unless toy want the phon to run 1 core and then toggle the second core on demand?

System Tuner has an option to force all CPU's online, but that may only happen at boot, and not keep them online.
possible hijacked this application? for use on atrix? : http://forum.xda-developers.com/showpost.php?p=10095647&postcount=22
System tuner will force both cores online. It can be set at boot or via init d. It will make your phone run hotter and increase battery drain. I didn't see enough of a performance increase to justify forcing both cores online. Logs show the second core kicking in when necessary.

Hi, I've discovered this app and decided to post in this section because of it's nature.....it enable/disable the 2nd core faster than any script or manual settings....i think it could be very useful in this Development section. It may help to reduce battery draining....especially on ics leaked based roms. No difficult mods....no scripts....no manual editing....no terminal emulator.....just install the app (with root), run it, ignore compatibility warnings and click the toggle. Reapply after every boot.
You can check it with this tool tegra2tableau.

I believe u can only turn off cpu1 which is actually 2nd core cpu0 being the 1st core

That's exactly what it does.
Anyone using memory management settings such as zRam, Allow purging of assets, and Kernel samepage merging? My Fassy has about 40 or less MB of RAM available at all times and enabling all 3 of these features sounds pretty appealing haha. Is there a disadvantage to enabling them? The description of what they do sounds like it's all advantage and no disadvantage. If I set zRam I would make it 18% (default). So my question is should I enable all 3, enable only 2, only 1? Lastly, any drawbacks/disadvantages to enabling any of them if not all? Thanks!

There's no disadvantages enable all the suckas that's what everybody does anyway lol it makes your device a hella lot faster I also recommend going into build.prop tweaks and enabling Just In Time Compiler

Yeah when I tap it it stays lit up for a few seconds then finally it goes away and still no check. I tested 3G Speed Hack and Optimize TCP...they take a while too but eventually do get a check mark just JIT won't get a check mark
