Squeeze control:

Pulsating notification LED video:

Button Light Notification

Kernel Ambient Display

Flashlight notification

Chromatic gradient colors for battery percentages while charging..

Requirements
- Unlocked HTC U11 with TWRP
-- Tested on European and HongKong HTC U11 (dual sim) model. Please report back about your device/model experience!
- BACKUP: make sure you backed up your original Boot partition in TWRP, before installing this! Installer only modifies BOOT (kernel zImage)

- INSTALL: Side load, or install the zip from your sdcard through TWRP
- Reboot.
--- If not using PlayStore Donation apps, then install CleanSlateCompanion-x.y.z.apk / CleanSlateConfig-x.y.z.apk from SDCARD (copied by installer if internal memory was mounted) Please grant Notification Access and the permission to read/write SDCard, read phone call status.
------ !! IF YOU UPDATED THE COMPANION APP, Don't forget to Open it again as well after update !!
--- use CS Configuration App to configure stuff without rooting
Companion application writes /sdcard/uci_sys.cfg to communicate with kernel, you'll find it there after first running the app, don't delete it.
--- instal kadaway flashables for adblocking, and after that set kadaway feature on in Configuration App : UX/Gesture&Extras/ K.Adaway ON

Known bugs:
- doesn't work well with PNPMod, please don't use them. Especially balanced mode can cause freezes.
- None, please tell

Set up, changing default settings
For newbies, let's start with basics.
1. This is a custom kernel, no additional applications included, and as such, does not change the UI, or add any additional menus for tweaking.
1.1 rootless, no tweak app, keeping Ota update possible guide here: https://xdaforums.com/showpost.php?p=74341460&postcount=1237
2. If you want to change the possible options of the kernel (see below the Sysfs endpoints for the broad list of possibilities), you can simply use the /sdcard/uci_user.cfg file to set 99% of the CleanSlate kernel options. Just copy/rename the preinstalled sample file uci_user.cfg_sample to uci_user.cfg, Edit in a text editor, save it, and it's set!

2.a: Use CleanSlate Kernel Configuration app (see post 1) - all CS features covered, using UCI interface, without rooting!!

2.b: Optionally if you have root, you can use also a Kernel tweak app. For this I suggest to use either one of the following: LeeDroid Tweaks by @LeeDroid, EXKM by @flar2
3. two small exceptions is
---- how you can set up Squeeze Control, without a kernel tweak app. Read the following post about this: Squeeze control setup
---- how you can switch between Full light mode and Low light modes. Read here: Low light mode switch
4. Clarification about Squeeze Control vs. Edge Sense/Edge Sense plus. If you plan to use Squeeze Control of the kernel, you need to know that you will need to leave free the Short squeeze gesture to be taken over by Squeeze control. If you plan NOT to use Squeeze Control, either do NOT set it up in system Settings, or disable it in the chosen kernel tweak application.
5. If the given kernel setting detailed below in Sysfs settings, you can still add them to EXKM with custom settings added in Advanced settings of EXKM and specifying the sysfs paths.

Good times, missed pulsating LED and KCAL control from HTC 10)

nice tbalden, happy you're developing too

any idea if you're going to implement EAS?

Unless the OP's philosophy has changed, I'm assuming this will be a mostly stock kernel with added features.

Thanks for the feedback. Going to add to details

Great to have this new device, easy decision to upgrade and do some kernel stuff again.
Led driver was replaced with something much more cryptic to program, so it's going to be a challenge to deliver all led stuff on the u11

=dave= said:

The idea of this kernel is to leave the core intact unless there's some really good reason to change it, like it was with the HTC m10 where the gpu is too much throttled by default. So far I see no need for changes like that to the core.

To tell the truth, HTC did a very good job again this year, so it takes some time to figure out what user experience feature is worth adding at all...
And that's a good thing IMHO

working on button light notification features... BLN is now working while not charging and while charging based on vibration pattern... will need some more parameters and whatnot, but promising.

Feel free to throw me some tests, will start adding the relevant Tweaks controls

tbalden · Jun 19, 2017

So here we stand now... A few things done, a few things left, but now this demo video shows a little something.
Button light notification turns on when phone is charging and notification vibration is enabled. Detecting event from vibration pattern and charge state

So you don't have to turn on phone to check if there's any new notification while it's on charger

tbalden · Jun 19, 2017

worked on sysfs configuration and some additional fine tuning... almost there!

tbalden · Jun 19, 2017

ok, so, as you may know one of my signature features is Button light notifications (started on the HTC One (m7) then on m9+ then on the m10 and now the u11), but this is the first time, it is possible to make Green led and buttons pulsating in sync

Tomorrow seems like a good day to release, after some final testing

The fact that I couldn't get the LED and BLN blink with the same frequency and in phase really drove my OCD nuts on the 10. Thank you for getting this done!

Working on US Unlocked U11 with 1.11.617.3 base. Magisk v12. No custom ROM (yet). Using on T-Mobile.
