sleekmason · Feb 13, 2014

SleekAI kernel for the LG G Pad 8.3 V510 (GPE)

Updated 1-22-2015 CURRENT Sleekai8.1
Both kernels updated to Fsync off (again) and a couple of small changes to code. Also changed the versions to match numerically.
Also added a new 88sleektweaks file for init.d that has preset values for voltage control undervolting, See second post for instructions and zip file. Use Trickstermod if you want fsync on.

Both Lollipop And Kitkat Versions
(Lollipop version also works with CyanogenMod12)

Features:

Flash Through Recovery!

Interactive Governer as default
Row IO Scheduler as default
Wheatley Governer added as option (Lollipop only)
Knock_on enabled by default (Lollipop) or with
My app in the third post down (KitKat)
Sweep2Sleep enabled as an option
LCD screen control using Trickster Mod
Compiled using Linaro Toolchain cortex a15-4.9.3
o3 Compile optimizations
init.d support (zip align, etc...)
Faux Sound Control added
USB Fast Charge added
Frandom replacing Urandom
Fsync On/Off using Trickstermod
Tethering for bluetooth and usb
Exfat support for sdcards
User Space Voltage Control TricksterMod to change
Five new IO schedulers for Lollipop! Trickstermod to change
And more!

The kernel source and Commits that show the changes used for sleekai can be found here: Github

Prerequisites
Unlocked bootloader
Root
Install Busybox for init.d support
TricksterMod is recommended for changing settings

How does this work?
Start by making a backup of your boot in recovery, then:

Flash the latest version in Recovery . Proceed to the downloads below, download to your tablet, reboot into recovery and install the zip --That simple!

if you want to build your own kernel start to finish with complete instructions, you can follow my guide for rolling your own kernel HERE

TO USE INIT.D SUPPORT ON YOUR DEVICE

Busybox must be installed for the init.d support file to work! (in the playstore)

You will need to add a folder named init.d to /system/etc/ in order to use this support

One example is to have your apps zip aligned on boot.

Another is to use my 88sleektweaks script to save battery
This includes undervolting values that you can adjust as neccesary, and a few WiFi tweaks.

Unzip the file to reveal the zip-align script. Then:

Copy the script to your /system/etc/init.d folder, change the permissions if needed, and reboot. Thats it!

You can tell you have it right by looking in /data for the zip align db files after you reboot.

You should change your permissions on any file in init.d to rwx r-x r-x (755)

Sleektoggle - For Knock_on and Sweep2Sleep

I made a small application using tasker that will enable Knock-on and Sweep2Sleep on devices using the kitkat kernel.

Knock-on is enabled by default in my Lollipop kernel - no app required.

The application works as a toggle, and will need to be "enabled" after every boot to use these features.

This is for your protection, as knock-on will freeze your device if enabled before or during boot.

This keeps you from having to enable these manually by adjusting the files yourself.

The knock-on feature should work on ANY 510 device, as it is native to the device.

To use:

Download and install the apk.

Put the icon from your apps somewhere on your home screen

after boot/reboot, press the icon, allow root privilages, and you are done!

You should only need to enable root the first time.

To use the features:

Simply knock twice in the center of the screen to wake up your device from standby

To put it to sleep, swipe from right to left on the lower portion of your screen.

Pressing the icon a second time does not disable the features. Restarting your device does!

Excellent! You can expect the first reboot to be slow, as well as the first opening of some apk's as the kernel repopulates the files. Let me know!

A lone V510 dev emerges!!! Thank you!

-Updated kernel for ability to pull the .config from the device, and shorter idle time before sleep.(battery saver). With this comes an updated name change to sleekai2.

sleekmason · Feb 19, 2014

--Update--

Kernel recompiled using the latest Linaro toolchain 4.9.3

Gamma corrected on the tablet with no further optimization needed

And the latest Antutu benchmark for the 510 with the latest Lollipop kernel: 31,526 See attachments.

gunnyman · Feb 19, 2014

going to give this a go right now.

Gamma looks GREAT!

nice job sir. Thank you.

evinkay · Feb 21, 2014

Just flashed on my V510. Thank you so much for your hard work!

general_z · Feb 22, 2014

Anyway to mod the gamma fix onto other roms (v500) via adb or something?

kdog350 · Feb 22, 2014

this is awesome! It feels like a brand new device!

Hi Sleekmason,

I tried your kernel by booting it but not doing the permanent flash to the tablet and something that I noticed is that when I am booted using your kernel I can't see or use my sdcard1 (external sd). When I boot off the normal stock kernel the sdcard1 is available again. I tried 2x and same result each time. Am I having bad luck and others can see their external sd card? The extra 64GB of storage is critical for me so even though I would like to try more your kernel and the improvements you have made I can't without the external SD card working. Please let me know if you know a solution. I don't know if this makes any difference but I have done the platform.xml change to be able to write on the external SD, that is the only change to the stock GPE Rom besides rooting. Thank you

huh, I don't have this problem myself using es file explorer, or in my settings tab under storage.

There should be nothing in the configuration to cause the problem you report.

I have however, heard that there were issues with some of the 64 gig cards. Have you tried removing the card and reinserting? I suppose it would be possible that it needs a new initial read after changing kernels. Please let me know.
Also what file system is the card?
What are you trying to read it from?

Check out "How to roll your own kernel" in my signature. There is somebody who is going to try to make a kernel for the 500. Unfortunately, without the device I cannot take the chance of making a mistake and ruining someone's day. Hopefully they will succeed!

sleekmason · Feb 23, 2014

-Update-

Kernel Added
Changelog 22 Feb 14
general setup-perf-changed to sleekai3
compiled with -o2 for optimization of code/better battery life, maybe.
general setup-kernel log buffer size changed to 14

Note* sleekai3 is pretty much the same thing as sleekai2 except the specific use of the optimize flag for the gcc compiler. Does it really change anything? Don't know yet. Wouldn't worry about changing unless you just can't resist. If I see noticable battery savings I'll let ya know. Of course, changing is easy too . . ..

How thoughtful of you.

In what file(s) is the gamma fix or where is the changelog that shows it?
I'm thinking that It may be quite easy to just to mod another kernel for the v500 and put it in (like dyn.Kernel v3).

Hi Sleekmason, thank you for responding.
I tried again this time with your new v3 kernel and I get the same results. The card is a Sandisk 64GB formated as exfat. I can read it no problem when booted on stock kernel and in W7. From the tablet I check the sd card from ES FileExplorer and from the settings Storage. When I removed and re-inserted the SD card while booted on your kernel I get the option to "Mount SD" but it does not seem that it can complete the mounting.

Have you modified your platform.xml file (under system/etc/permissions) to allow writing to the SD card?
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
add line : <group gid="media_rw" />

Without that change I could not write to the SD card but only read from it on the stock kernel / rom.

Are you able to read and write to your SD card with your kernel?

Yes, I did the fix as well. The sleekai3 is only the optimized sleekai2 (using flag -o2), so there really is not much difference.

SO, here we go, I looked up problems with the 64 bit card as I remembered reading something about them in a samsung forum. What I found this time I searched was here: http://forum.archosfans.com/viewtopic.php?f=84&t=66346 and here in our own forum: http://xdaforums.com/showthread.php?t=2575043
Basically what "they" say is that the Sandisk 64 bit cards have issues with exfat. The solution is to format in fat32. you lose a gig or two with the different format, but it works. The above link also suggests ext4 as an option, but it will not work on our device, neither will ext2. At least not mine!

Long story short is to copy your files to your computer, reformat to fat32 and put them back!

The longer story is of more interest to me. As sleekai3 is based off the original kernel source for the 510, and because I have made no changes to areas that should/could effect the reading of your card, WHY does the stock kernel you have allow it? (yes, I switched it and am assuming it is unreadable by every kernel for the sake of argument.)

This is entirely a permissions issue as far as I know. frustrating. One thing I cannot do with my card is download a file, say a zip file, to my external sd card. I can copy it after it's downloaded, I can use link2sd with no problem, everything shows up well. This indicates the need for root access by Dolphin Browser.

I had thought to edit the fstab file and simply add "users" to the options but that doesn't work. I also tried many variations of the fix in the /permissions/platform.xml as well.

I'm going to have to study permissions for the device and see what I can do to fix it for everybody if I can. I'm afraid that adding the card to root could allow for an exploit. maybe.

Anyway, reformat to fat32 and let me know how it goes! regards, sleekmason
