Installation
Flash in TWRP recovery or use ElementalX app

Notes

-All settings can be adjusted with the ElementalX app

-Defaults to stock CPU frequency, to use higher frequencies, do this:

Code:
echo 2499000 > /sys/module/cpu_tegra/parameters/cpu_user_cap

GPU is not overclocked by default, change like this:

Code:
echo 984000000 > /sys/kernel/tegra_gpu/gpu_cap_rate

-USB fastcharge is disabled by default, to enable:

Code:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
-fastcharge increases input current from 500mA to 900mA.

Happy Flashing & [COLOR=#ff0000]flashen wie immer auf eigene Gefahr![/COLOR]

Aber mehr als sichi... wird beim N9 nicht anders sein als beim N5,N4, ...

Das wird auch keine "Stunde alt werden" bis ich Unlocke, ROOT & Flashe! :moustach:

[COLOR=#ff0000]Another test release.[/COLOR] This one has voltage control.

I am going to revert voltage control in the next release, because this device has dfll mode enabled by default and it scales the voltage automatically and probably does it better than any tweaking we could do (the dfll mode voltages are lower than the software controlled defaults).

I just offer this for testing and other devs may want to use it. For now I will be going back to the automatic dfll mode.

ElementalX-N9-0.03 alpha

The next version of the ElementalX app can do it. I'm working on it right now and will push the update later tonight.

[COLOR=#ff0000]Update[/COLOR]

ElementalX-N9-0.4.img (alpha)

Changes:
-revert linaro fixes
-revert voltage control

Update!!!

-This should fix the problem with Asian keyboards.

-Add GPU overclocking, mine goes up to 984, let me know what your max is (it might be different)
GPU is not overclocked by default, use the ElementalX app or do this:

Code:
su
echo 984000000 > /sys/kernel/tegra_gpu/gpu_cap_rate
-big changes to zram, I backported from linux 3.15, which adds support for lz4 compress/decompress (faster) and multiple compression streams (I have set it to 2, same as the number of CPUs)

-add exFAT filesystem support, you need Stickmount or something to mount the disk

-no forceencrypt on /data. If you are using previously installed system, you data is still encrypted, which is good.

Latest commit from google.

Changes:
-Turn off memory cgroups

UPDATE!!!!

Now that there is a recovery, I've made a [COLOR=#ff0000]flashable zip with Aroma installer[/COLOR]. If you just want to fastboot flash, grab the boot.img from the /boot directory in the zip.

I haven't updated the ElementalX app to work with all the new settings yet, I will do it on Friday night.

The installer is pretty complicated, there could be bugs. Let me know if any settings are screwed up.

Settings are stored in /etc/elementalx.conf and can be changed by editing this file.

This release has sweep2wake/sweep2sleep. You can select any combination of sweep up, down, left or right. Or just use the built-in doubletap2wake. Or use doubletap2wake and sweep2wake. Any combo will work. Some of the gestures might need a few more adjustments.

Sweep2sleep turns off the tablet screen by sweeping along the bottom or top edge of the screen. Default is the bottom or top edge in portrait mode. I don't use landscape mode because it can accidentally be triggered while scrolling in portrait mode. But you can enable sweep2sleep in landscape mode if you want. You can also enable it in both portrait and landscape, in which sweeping along any screen edge will put the tablet to sleep.

Also added an option to disable fsync (not recommended, but can increase performance)

Download:
ElementalX-N9-0.07 (alpha)

Changes:
-add sweep2wake
-add sweep2sleep
-add option to disable fsync
-add aroma installer
-add elementalx.conf

Update!!

Added some battery saving optimizations, BFQ i/o scheduler and download/install compatibility with ElementalX App.

Download:
ElementalX-N9-0.08 (alpha)

Changes:
-various optimizations
-BFQ scheduler
-app compatibility

Kernel & OP UPDATE!!!!

For this update, I went back to the Google toolchain. Also grabbed the dm-crypt updates and optimizations from faux. Added 2A charging, if you have a 2A charger. It will charge normally with the stock charger. And finally, added SIO and FIOPS i/o schedulers.

Kernel Update ...

Update!!
I've changed the installation process to use the existing ramdisk. This should solve problems with selinxu, theme changer, etc.
Please don't install over other custom kernels. Best thing to do is dirty flash your ROM and then flash ElementalX.
I've also enabled the built-in hotplugging. I don't think it makes much difference, but we'll try it for this build.
Other than that, no actual code changes.

Kernel & OP Update

Zitat

Update!!!

This includes the initial version of the elementalx governor. I will probably be tweaking it some more, so feedback is appreciated. You can mess with the tunables in the ElementalX app.

I've added support for the Wake Gestures app (ElementalX-N5-2.09). This allows you to set custom actions/shortcuts/apps for sweep2wake and doubletap2wake. It's a standalone app, not an xposed module.

Regarding xposed, I've relented and added a permissive option. You need SuperSU to use it. Don't set permissive unless you need to.

I turned off hotplugging, as it didn't seem to help battery and may have affected performance slightly.

I've also removed fastcharge and 2A charging, as there were reports of slow charging.

Update!!

No changes to the actual kernel, just installer updates. The permissive script was not running due to incorrect permissions. I've also added a line to format cache to ext4 during installation.

I've also made the express installer available, since the recovery is very slow with Aroma on this device.
