Core Control

Can I control cores activation ?? like can I deactivate one core and let the phone run on 1 core ? you know it saves battery and voltage if the phone is in sleep and no activities are going on .. (at least thats how it is from my point of view)
[AT&T, Rogers HTC One X, Telstra One XL] KungFuCracka94:
You can use the app [MENTION=4153349]timmaaa[/MENTION] mentions above your post as well as Kernel Tuner. However, I believe restricting core usage puts a lot of stress on your device. Some users claim that undervolting and reducing max freq to 13xx MHz does wonders for battery life without affecting performance. I'd say attempt that before locking your phone on a single core.
[AT&T, Rogers HTC One X, Telstra One XL] Heisenberg:
I agree. I wouldn't restrict my phone to a single core. You can usually underclock to 1242mhz without suffering any performance decrease, you can possibly go lower but I haven't personally tested any lower.

Hi not being picky but want to give honest feedback.

On 1.4 I see a general laginess that I don't see in 1.3

May be it is the cache oc?
[AT&T, Rogers HTC One X, Telstra One XL] flar2:
It's probably not that, there is a problem (not just in 1.4) where sometimes the 3D GPU max frequency gets set to 200. It should be 400. I'm still trying to figure out why this happens. Usually my init script takes care of it, but sometimes it slips by.

You can check it and set it with Kernel Tuner or by making sure /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk says 400000000

Once you set it, it seems to stay at 400 max, at least until reboot. Note: in kernel tuner we're not looking at the current frequency (which scales between 200, 300 and 400), but the max frequency.

EDIT: I've also found that sometimes the max freq of the second core is not getting set properly. I will post an update with a fix for this and the GPU problem tonight.

Myself, I've been setting it manually with kernel tuner after checking what its reporting as 3d max speed and setting it at 400.

Yes that is correct. since my last post I have downloaded and installed a new copy of this kernel and so far it is working perfect. Before when the phone went to sleep I would loose my carrier cell connection and had to reboot to get it back. This problem was intermittent, however the fresh installed kernel seems to be working great at this time.

Which is good because I ran an earlier version before and really liked it.

Apparently there was a problem with the previously installed kernel...
