Definitely a decent kernel. But when i tried it on EOS 3 it bootlooped. Is it because it is intended for EOS 4 or because of i have to wipe cache after flashing?

running dreamcwli's 4.2.2, and it's all butter. can't wait to see how much better it's going to be when elemental-x gets updated!

i was using trickster mod, which works great (and can set s2w / zram / gov / io sch). but to consolidate apps, i just use rom toolbox pro. since s2w and zram are enabled by default, i don't need to be able to manipulate those settings

Nope, same as before, 4G icon is grayed-out, never shows it trying to connect. Once I enable airplane mode and then disable it, the 4G signal icon never appears again.

Running Baked v7.

Are there any logs I can provide to help troubleshooting?

If you could, please reboot and then type (in terminal emulator):

dmesg > dmesg.txt

and send me dmesg.txt

I was wondering whether it would work on the older ROMs. Thought maybe it would. Has anyone else tried it?

Are these any good?

Re: [KERNEL][Feb16] ElementalX-Xoom-v0.5 | OC | UV | GPU OC | ZRAM | SWEEP2WAKE

Had to revert back to the original kernel on My Android - everytime I try to clean the screen I end up rebooting the device using power+ vol up. I think all of the edge to edge wiping is locking up the device. An idea for future development would be an option added to Android settings to check or uncheck the sweep2 wake feature.

Other than this, good work and looking forward to the next iterations of keeping the Xoom alive.

I tried it once again on EOS 3 and this time with wiping but still bootlooping. Too bad. I love the features though.
I didnt know that people would want to upgrade to 4.2.2. The lag is out of comfort zone. Does this kernel reduce the lag significantly?

I'm at work today, but I'll have a look at these this week.

Good to know, I will have to put some limits on the sweep2wake function to ensure that doesn't happen.


For now, you can disable sweep2wake by setting /sys/android_touch/sweep2wake to 0

To disable:
echo 0 > /sys/android_touch/sweep2wake

To enable:
echo 1 > /sys/android_touch/sweep2wake

This happens in real time, no reboots or anything necessary.

You can also navigate to that file using ES File Explorer (or something like it) and editing that way (less typing;))

I've only tested this on EOS 4 and My Android, though others have confirmed it works on Baked 7.

Are there many people still using EOS 3? There doesn't seem to be much activity here (only 123 downloads of version 0.5) Someday when I have the time, perhaps I will release versions for EOS3 and CM10.1

flar can feel free to correct me, but i'm pretty sure you can't use a kernel built for 4.2.x on a 4.1.x rom.

I think sweep2wake consumes battery in deep standby so is there any possibility to add an option for using volume keys to wake up the device?

Or is this rom related?

Thanks for you quick reply :)

Using the Xoom (on the couch and on my knees ;)) with applied genuine portfolio case it isn't that easy to reach the powerbutton than the volume keys.

I seems that I have to give sweep2wake a try.

    • doubletap2wake
    • Overclock to 1.7GHz
    • user voltage interface
    • GPU overclock
    • OTG support

    INSTALLATION

    Install zip from recovery.

    You must have an existing working kernel for the ROM you are using, and you must reflash this kernel whenever you change to a different ROM. The reason is that the universal installer injects the ElementalX kernel into whatever boot.img that is currently installed.




    Please hit the Thanks button if you download this

    If you really like it, please consider buying me a beer

    Actually, I won't spend it on beer. I'm saving it up for my next device :D

    ​


    NOTES:

    Compatibility
    Works on all Xoom models: wingray, stingray and everest. As of version 1.0, it should work on any ROM. I have tested it on EOS4, My Android, CM10.1, CM10, Baked BB8 and Orca. It should work on others, including Android 4.3


    Versions
    The vanilla version does not overclock the graphics. I recommend using the regular version unless you are specifically having issues due to the overclocked graphics.


    Configuration
    The config file is located at /etc/elementalx.conf. You can edit this file to change kernel settings. Whatever is set in this file will take effect when the device is booted. A log file is stored at /data/local/tmp/elementalx.log


    Sweep2Wake
    I totally revamped sweep2wake. To put the screen to sleep, you now have to swipe along the edges. You can swipe anywhere to turn the screen on. There is a new option for sweep2sleep only.

    0=disabled
    1=sweep2wake/sweep2sleep (default)
    2=sweep2sleep only

    /sys/android_touch/sweep2wake


    There is also an option called shortsweep (enabled by default) so you don't have to sweep all the way across the screen. You can turn the shortsweep option off.

    0=disabled
    1=enabled (default)

    /sys/android_touch/shortsweep


    Doubletap2wake
    Doubletap2wake is another new feature. You can turn the screen on by double tapping anywhere on the screen.

    0=disabled
    1=enabled (default)

    /sys/android_touch/doubletap2wake

    If you are one of those with sleep of death from sweep2wake, you might want to try sweep2sleep only and doubletap2wake disabled. Then you can still sweep your screen to sleep, but the touch driver acts completely as stock during suspend.

    All these options can be changed in /etc/elementalx.conf so they are automatically set at boot.


    zRam
    zRam creates a compressed block device in RAM that is used as swap. Although it claims some of your RAM as swap, everything written to swap is compressed. This increases the apparent memory available to the system and helps with multitasking. Swap files on disk are very slow, but with zRam the swap is on RAM so it can be read as quickly as regular memory. Even though the data need to be decompressed, modern CPUs can decompress quicker than if it had to be to read from disk. The penalty is cpu usage, which could drain battery; however, this is likely negligable in daily use. I didn't enable this by default because not everyone will want it. This is for heavy multitaskers and will allow you to quickly switch between more apps and have more tabs open in your browser without refreshes.

    zRam is disabled by default. If you want to enable it, edit /etc/elementalx.conf
    change ZRAM=0 to ZRAM=1 and reboot.

    You can check if zRam is working by typing the command "free" into the terminal. You should see the total used and free swap. If these are all 0, then zRam is not enabled.


    Governors
    Intellidemand is the recommended governor, but there are several to choose from. If your ROM has performance settings, check that your desired governor selected.


    Max Screen Off Frequency
    You can toggle max screen off and change the max screen off frequency by editing /etc/elementalx.conf.

    If you want to edit the settings directly, the sysfs entries are at /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_enabled and /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_freq
    Editing those files doesn't persist after a reboot, if you want the setting to persist, edit /etc/elementalx.conf

    If you have instability or reboots while the screen is off, disable max screen off frequency.


    exFAT support
    There is also optional support for the exFAT filesystem. A module has to be loaded for it to work, it is not loaded by default. The option to load it at boot is in /etc/elementalx.conf

    These are compatible with the bigpart mod. Don't flash unless you did the bigpart mod!!!

    There are lots of other changes too, check github if you're interested. Let me know how this works.

    These are BETA, I just built them tonight. They should be fine though.
