So, I finally got bored with my tablet and decided to start development on a new kernel for Ice Cream Sandwich on this tab (so futuristic, I hear you say!).\
This kernel is for the Galaxy Tab 8.9 (GT-P7320T). I suspect the kernel will work on the GT-P7320 as well but can't confirm.
Note that flashing a kernel is not for the faint hearted and the "how to" for that is best handled by other forums like XDA developers.
The features so far are:
- Interactive CPU governor available for selection (was left out of the stock kernel for some reason). If you want to enable this governer you will need to firstly get ROOT for the tablet, and then install some app to control it, e.g. Voltage Control. If you enable this, it should give you a more responsive tablet, compared to using the default ondemand governer.
- Max CPU frequency "UNICPU" bumped to 1512MHz from 1242MHz. This is the maximum frequency that you will see the tablet sitting on at times. If you are concerned about battery usage you can tweak this the maximum frequency value down using using Voltage Control or other apps.
- USB charging and notification, as per glitschi667 / pershoot's patch, which was previously in a honeycomb custom kernel: http://forum.xda-developers.com/showthread.php?t=1569122 . The tablet will show as charging when plugged into a PC with enough power, whereas previously you would see the red X over the battery icon.
Download version 1.0 here: https://sourceforge.net/projects/kernel-p7320t-ics/files/ Available is both the standard CWM flashable ZIP, and another ZIP which contains an ODIN flashable .tar.md5.
(If you don't have a recovery or Odin, please check the original XDA post but do not flash the kernel from there as it is not an Ice Cream Sandwich kernel: http://forum.xda-developers.com/showthread.php?t=1569122)
The source is available here: https://github.com/CL0SeY/kernel_P7320T_ICS (If you need help in making/modifying the kernel from source please let me know.)
Any feedback is welcome.
