Yes there are. However, he wants this particular kernel ported. I'm guessing there are some features of it he wants, it has never been stated clearly.

Signature? Signature!
[Nexus 7 (2013) Original Android Development] flar2:
People ask me to make ElementalX for all different devices. I could throw together a bunch of patches and release it for other devices, but if you want a good kernel, you have to spend a lot of time testing and tuning everything specifically for the device. Pretty tough to do if you don't have it. Right now I'm supporting the HTC One, Nexus 7 and Nexus 5, and occasionally the Motorola Xoom, HTC One S and HTC One XL (not updating the last two anymore). It's a lot of work.

For battery life, I think the defaults are good. You could disable gboost, but I don't think it makes much difference and it's smoother with it enabled. Disable s2w and dt2w if you really want it to last. I went a little more for performance in ver 2.6. I don't worry about battery life too much on this tablet. We leave it laying around the house for anyone to use. It often goes for several days without charging.

So if you want your device to have flar's kernel on it, donate the $$ or same device. Ta da :p
[Nexus 7 (2013) Original Android Development] flar2:
$$ is one thing, time is the other. This takes up all my time right now, so I don't think I would even be able to support more devices.

I cannot change to ART, after rebooting it still uses dalvik. I am stock 4.4.2 rooted. Nexus 7 2013 LTE
[Nexus 7 (2013) Original Android Development] deedeeceleb:
That's most likely because you're using xposed which is preventing the device from changing to ART, because it isn't compatible.

Flar2, I noticed you raised the default clock speed to 1.7 GHz in 2.5, but you dropped it back to 1.5 again in 2.6. Any specific reason for that?

The elementalx governor is very good for battery life. I am getting amazing results at idle with it and the device sleeps great. The only thing is that it lags a little in games but I just switch to ondemand and things aren't so bad.

im on 2.6eX now oc only to 1.736ghz, i thought 1.85 was too much drain on battery , so i clocked it down a bit, uving helps keep it cool but i think it still gets hot near the camera hole when playing videos, i don't game so i assume it gets alot more hot!

Battery life is amazing, I had 7 hours screen on time with 40% remaining when I went to bed last night
[Nexus 7 (2013) Original Android Development] optimusG:
With what ROM? I am using the latest sinlessrom with this kernel but with screen on I can't achieve battery loss less than 1% per 5-5.5 minutes (which means with 7 hours screen on I loose at least 75%). Of course it has to do with the syncs, usage etc.

I am using the device's stock settings with a slight U/C.
[Nexus 7 (2013) Original Android Development] Michealtbh:
Stock with Xposed and Gravity Box. I'm actually overclocked a bit (both CPU and GPU) to achieve the same ui fluidity as my N5, undervolted -50mv across all frequencies. My usage mostly consists of browsing Tapatalk, reddit and G+ with very little gaming so it's not very intensive. Sync, wifi and auto brightness always on.
[Nexus 7 (2013) Original Android Development] optimusG:
Maybe undervolt helps a little. :good:
[Nexus 7 (2013) Original Android Development] SupWiz17:
I'm running the latest psx and the ROM is very smooth. Battery life with it and this kernel is phenomenal. The only downside is that deer hunter 2014 lags big time but I think with the on demand governor I can fix that.
[Nexus 7 (2013) Original Android Development] wantowan2:
I have used this kernel on other projects and it's been great. However, I am working on a prerelease rom that is essentially CM based and is basically ready. I have been testing various kernel combinations and have run into trouble. I fully tested the rom prior and was happy. After flashing this kernel, I noticed that the bootanimation (display) was scrambled and when the os came up, everything had a blue filter. People looked like a smurf(sp?)... lol Aswell, it was as tho (I cant say this for sure) the device was running on only 1 partial core.

Please see attached logs.

Hey guys what battery life do you get with this kernel?

Enabled s2w dt2w I managed only 5-6 screen on time.
[Nexus 7 (2013) Original Android Development] ObiDanKenobi:
I have disabled s2w and dt2w as I have a smart case, using CleanRom I get 13h on average and almost 18h max. I do not play on the tablet but I used Skype video for about an hour

[Nexus 7 (2013) Original Android Development] konradsa:
18 hours with 1 hour of Skype? That is insane! How did you do it?
[Nexus 7 (2013) Original Android Development] ObiDanKenobi:
The usage pattern is very light, was something like 1h Skype, 7h browsing the net with Dolfin or Tapatalk. The rest was using play books to read Enders Game, with Wi-Fi off.

I use lux to control the brightness, it goes between 10 and 35%, so for 10h the brightness was very low, I think that this is what did the trick. Anyway 18h is indeed very long, but I get regularly 13h.

I have tried it now with the right Version. When I connect the DAC I hear no sound from intern Nexus Loudspeakers but there is also no sound from the DAC :(

If I try the same with my Nexus 10 it works without problems so i suppose that the DAC and the connection is ok.

Has anybody an Idea what to do to make the DAC run?

Kind regards

So if we want to try this kernel and we have anything other than the stock kernel we need to flash just the boot image not the entire ROM we are on? Where is the boot image?
[Nexus 7 (2013) Original Android Development] wantabe:
You need to dirty flash the rom. If you have a nandroid from Before you started flashing kernels, you can flash the boot and system from your backup in recovery. Personally, I think that is by far the easiest/best way to start with a clean slate when trying different kernels. Also, if you have modified any system files like mixer_paths or fonts or whatever you will not loose your mods if you flash from Your backup. You do not have to flash all of your backup, you can flash whichever part you want. Or... you could pull the boot and system image from the factory image and flash with fastboot. Or... you can flash whatever rom you're using in recovery. Stock 4.4.2 I haven't looked but I'm sure there is a flashable zip for the current stock kernel if that's all you want to do but I would flash the system also.

This kernel is 100% stable and rock solid, I'm just keeping it in beta status until all the features and settings are tested. I want to make sure all the settings get applied and that there are no bugs with the installation, etc.

There is now an option to use a short sweep for sweep2wake. I think I like it, so I encourage you to try it.

The other new feature is the ability to enable or disable the magnetic on/off function. If you don't like the screen automatically turning on or off with a magnetic tablet case, you can disable it.

I made fiops the default i/o scheduler.

I experimented with kernel based thermal control, but right now I don't think it's better than using thermald. This tablet doesn't have very good cooling, it gets hot fast. I'll play with it a bit more and may add it with a couple options in the next version.

Other than possibly changing the thermal solution, I think this is feature complete.

Download:

ElementalX-flo-0.8 *BETA*

Changes:

-adjust Makefile options

-adjust doubletap2wake

-fiops is default i/o scheduler

-cleanup from other kernels

-add shortsweep setting for sweep2wake

-option to disable magnetic on/off

Undervolting through the kernel setup only will adjust the minimum clock voltage, not all the voltages based on the clock.

So if you under volt to 850 which is 50mv less, the top end max clock voltage isn't changed.

That's what I've seen, I could be wrong tho...
