Yeah the ones I rairly use...

I should just uninstall them. Lol.. actually I forgot about them all... I went through them and now I have a total of 15 restricted....

Talk about out of sight, out of mind. Lol
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] metaxda:
which kernel release are you using?

(the latest one?)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rob_z11:
How do you restrict those apps? If they are not being used, would they still use the battery?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jaythenut:
Go to apps pick the app and is in there
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
Latest no zram (0625)

Who Is Reno ice? Can share fou profile o settings of Nolimits?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
Sorry... It's Renovate Ice 13.0... it's a (Rom) module..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] metaxda:
you are using xXx and Renovate Ice together?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
Yes it actually is a great combo... I've had zero issues with running both together..

Check out the threads on them..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jaythenut:
I'm using xXx not using zram what about you ?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Unfortunately renovate is not compatible with beta
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
I have it disabled too.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
TEST KERNEL!!!!!!

What's inside (and let's see if it's better in the next few days):

- Updated GCC to latest 9.1 stable, with fixing a few new coding errors caught by the new compiler

- Removed OnePlus's code in the following: scheduler, binder, low memory killer (the kernel will no longer simply kill background apps!!!!)

Please note that this kernel doesn't have ZRAM support!

Also, please give me feedback on how it works for you all:

- smoothness

- battery life

- compatibility in general

- stability

Thank you for all who are willing to test this!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jaythenut:
Downloading now ?

See if the last 50% does better lol
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Please don't judge by the last 50%. Do at least a full cycle before looking at battery life. :)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jaythenut:
Yeah I will love to know what's killing my battery unless it's just a bad battery it self
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
99.9% of the time it's one of your apps.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Those who downloaded - any initial feedback?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Marcos Requena:
hello I do not write in this forum because I do not speak English but I hope that it is understood. This one that in the last Kernel I am trying is very smooth.

I also see that you have managed to keep the frequency to the minimum true
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] franco985:
I have flashed right now and I am testing... I give you a feedback asap....ps i think it promises well
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] franco985:
[MENTION=1795993]kristofpetho[/MENTION] I am interested in your modifications. Could you explain what do you mean with ' the kernel will no longer simply kill background apps!!! ' ? Thanks
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
Can't say for thr battery yet cause havent had the time to do a full cycle. But the smoothness and performance for me is a big difference. Everything is just snappier! Thank you for your work!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rezapatel:
Performance does seem to be great, but for some reason multitasking isn't as good. Apps seem to be killing almost immediately after going in the background.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] PokemonTotalWar:
That's not my experience. I have good multitasking and performance, and while it's a little early to really report, this is the battery on my first full cycle:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rezapatel:
Could probably be a one off case. I'll retry after a restart.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
Also active and idle drain got worse in my opinion??
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rob_z11:
Can you install it on latest beta?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
My findings with the test kernel:

Idle drain is the same, active drain a bit worse. But the phone definitely gets hot a lot faster...

Battery stats on testing right before bed:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
Give us the same kernel but with GCC 8.1(?) let's test together :D
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Yes

I'm running it on beta 13

Great ram management on latest build indeed..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
Little cluster is at 300mhz for min. It's supposed to be 576 right?

I'm on new test build..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Yeah, I know... I have actually reverted the test build commits. Phone got really hot after 5-10 minutes of usage, I'm not used to that.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] lendawg:
I flashed it at 50 percent battery yesterday, charged last night and took it off the charger around 9pm. Overnight I lost 1 percent battery and it seems to be about the same for active use as the last kernel but feels smoother. No heat issues here. I can't complain it seems great to me so far I'll see how it does by the end of the day. I had a few of the previous omega kernels heat my phone up initially but when I rebooted the problem went away so I don't know. Anyway, I hope this helps.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Yeah, I personally never had heat problems, only with the new test kernel. And this morning I flashed a new kernel I just built without the commits in the test and again no problem with the heat...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
Where did the perfomance boost come from? Commits or GCC?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
Test build is definitely snappier than the others for me.

I know that placebo may be a possibility, but how fast certain apps are opening compared to before is really noticable..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] lendawg:
Same here
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Commits

Can you guys let me know your thoughts on battery life? I don't really want to compromise on battery life to make things much snappier.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
Battery for me was not good compared to older builds. Idle and active went down for me.

Btw, can we test the commits on GCC 8.1?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
I don't think that will make a difference. I now have a test build with June 25 base + GCC 9.1 + one battery saving commit and all is back to normal...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] lendawg:
Battery seems on par with 6 25 but probably too early to tell for sure. Haven't gotten thru the first cycle yet.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] lendawg:
This is what I have currently.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Someone can check what is the default cpu boost settings from the kernel?..

Im running xXx mod and latest omega
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] franco985:
450
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kitcostantino:
Here is default. and the one change i always make on kernel....250 ms vs 500 ms.

scratch that [MENTION=3635587]franco985[/MENTION] was right. it is 450.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Ok thanks, can you check also the I/O Scheduler ?

For me is cfq & 2544 kb readahead
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] franco985:
Cfq 512
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Ryano89:
That's the default setting for the "kernel tweaks" option in xXx
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Yes i know...

Just want to compare with the omega default settings
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Ryano89:
Sorry I thought you wanted to know if that WAS the default. I should have read more carefully
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Omega default is 512kb and CFQ - which is the CAF default
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] PokemonTotalWar:
Used ADB forgetting it would charge for a minute so it's slightly inaccurate, but only a few percent off:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rob_z11:
Too many random reboot on test kernel.. going back to the last omega with zram.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Well, I did say the test kernel doesn't support OpenBeta/ZRAM...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rob_z11:
No, I totally understand, and no complaint here. One of the other user was using this for beta. :D
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:
Yes im using this in beta because I've disabled the swap- zram

Otherwise you can't use omega ( no zram version ) on beta
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rob_z11:
Are you running the majisk module which disables the zram?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] PokemonTotalWar:
About to charge after my first cycle with the test build
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] maxq1:
i dunno, man. test build giving me better batt life than the last few stable. i usually end up just 5+ hours SOT on previous. sorry didn't chime in before. with the test build i'm already close to that and i still have 38-39% left. same usage. dual-sim, couple of magisk modules & substratum themes

can't really say anything about snappiness coz i guess i've been spoiled by this kernel already :D
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
New releases!

The test kernel totally messed up OnePlus's thermals, so for the sake of our device's stability I have reverted all changes in the test kernel.

Changelog (this release is based on June 25 stable release):

- Updated to GCC 9.1

- Fixed a coding error caught by GCC 9.1

- Added a power-saving feature to the kernel

Please use non-ZRAM version for stable (it's working fine for me on latest 9.0.15 stable), and use the ZRAM version for OpenBeta.

For OpenBeta - Under Setting - Utilities - please disable ALL of the options to ensure no random reboots occur
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] franco985:
downloaded and in test...first impressions: I feel smoother than last test build. Active drain is very low. Oos 9.0.7 magisk 19.3
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] lendawg:
I don't know man I had zero issues with the test kernel. Drained 3 percent overnight which is about normal and no heat issues. Thanks for the new build though man! Downloading now!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
I updated to 9.0.15 and used phone for about an hour with stock kernel...

Just flashed new Omega(0703) build and I certainly notice phone being less sluggish...

Thanks for the great kernel

On Internet there are always reviews that the oneplus 6 / 6T is so smooth.

I did realized in day one I owned this device that it is not.

Even my Poco F1 phone is smoother.

I am happy that we have such good kernels like the Omega kernel,

There are 9 options (I'm using Beta 13) under Settings -> Utilities, do you suggest turning all off, including gaming mode, pocket mode, quick reply landscape etc?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Sorry, only the things under OnePlus Laboratory. Not the one in your screenshot. Apologies for the confusion.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] PokemonTotalWar:

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Ryano89:
Too early to tell about battery life, and I don't know if it's the new version (been on other kernel for awhile), or the update to . 15 stable, but performance on the latest kernel seems outstanding. Great job
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] cultofluna:

Are you still having reboots with those options disabled under OnePlus Laboratory?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] robbieast:
I'm no developer by any means, but was is the benefit of disabling debugging? Surely whatever it does isn't just a placebo
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] replica9000:
May be too soon to say anything, but already averaging 1h SOT per 10% while web browsing. I usually only get 6h SOT per cycle while web browsing.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kitcostantino:
i also am not a dev in the least, but i can see how one could deduce that, but if you think about it, debugging going on while you are not actively debugging is kind of a waste. just my best comprehension of it, not to say i know wth im talking about. at least, thats my best guess why that makes it more efficient.

in other news , just updated to 9.0.15 and newest omega. woot.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] replica9000:
I suck at explaining things, but I'll try. Debugging in this case, is like the kernel is logging everything that's going on. While you're interacting with the OS, messages are being sent to stdout or stderr, though there's no open terminal to actually see these messages. On a typical Linux system, much of these are sent to files under /var/log. Maybe someone can explain it better
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] PokemonTotalWar:
Best way I can explain it to a non-developer: Debugging takes CPU cycles, and perhaps other resources on the device. It's the equivalent to you multitasking, doing one important thing, and one relatively useless thing. You're going to do the important thing slower because you're trying to do the useless thing as well
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Texan1:
I had been running on stock kernel with beta for several days to test if any reboots and didn't have any.

Then because your previous test release a few days ago was a non-zram version I didn't try it and have been testing new Radioactive kernel instead and thankfully still no reboots.

Soon I'll go back to latest Omega and try with 'Smart Boost' disabled and see how that goes.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] theDUD3:
9.0.15 is out so can I just flash the update? Also has anyone tried the latest Omega with the new update, is it working?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Blackblock92:
It also works great on 9.0.15
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Yes, works just fine.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] franco985:

Done updating to 9.0.15 and installing Omega, thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Kovhl:
I get only 6 .5 hrs SOT for 100 percent . Is this normal .

9.0.5 , omega is 6.25. others seems to have 6 hrs for 50 percent.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] lendawg:
6 and a half hours for 2 days is really good imo
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ..Cory..:
You guys gotta give the dev a break :p I try to do about 3-5 cycles to get good battery results - from 100% to <20% every time. The first cycle after flashing usually won't show true potential. Especially when you're wiping cache and what not.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
It all depends on your usage. I usually get around 6 hours SOT over 24 hours unplugged. Anything above is incredible. To compare, with my iPhone 8 Plus I only got 3-4 hours over 24 hours...
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ..Cory..:
Oh, don't remind me... My iPhone X is something I'll never go back to, I wasted my money. Devs doing incredible work with kernels here spoils me away from my iPhone. ;)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
New releases!

..sorry for 2 kernels in 2 days... I promise not to tweak until next week... :)

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] franco985:
I am agree with you
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Kovhl:
Any possibility of RGB values and contrast ,level controls in future ?? Like it used to be there in kcal , and Cm13 display settings... We can adjust contrast and level in kcal, and RGB values from 0 to 255 separately in display settings.

I have read OP that such requests will not be done since it will cause heaviness / overload on kernel.

But I dont know if this feature will spoil the lightness of the kernel .

So asking.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
It was implemented in 0526 or 0529 build i think? But removed in 0603 for the stability of the kernel.... And battery ?

Back using latest July 4 Omega zram version, with Beta 13, Smart Boost turned off, so far so good after 24 hours, will keep monitoring :good:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] PokemonTotalWar:
I had a REALLY bad run with the new version on my last cycle. 18hrs, 3.5hrs SOT, at 20%. Usually I'd be at 40-50% on this kernel with that amount of on time. Hopefully next cycle is better, the one before was :eek:
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kristofpetho:
Any further feedback on latest build? Anything needs to be fixed, or reverted?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] wooki:
Still testing but didn't notice any difference to the build where you disabled gpu based logging / debugging.

My battery meter has dropped in screen on averages from 10.5%/hour to 9.9%/hour. Screen off usage has dropped from around 1%/hour to 0.6%/hour.

But that's just my first run. Need more data. ?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
Performance no problem at all. Smooth as always. Active drain is also great! Wasnt able to get a screenshot, but I got 7hrs 30 to 8hrs sot. Great for me im on OP6 :D no problems for me! Thank you for your hardwork!

I know you're busy busy with the builds my man... Any possibility for DTS support?

Thanks again!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] pooch11:
Been using this kernel since May and no complaints. On the latest build and can confirm I had 35% left before charging with 5h30m screen. Keep a few things in mind...

1) I always have LTE on - otherwise why bother having a phone?

2) BT is always on in case I hop into my car

3) Screen brightness is usually always full except when it's really dim in the room.

As I said no complaints. In fact, the kernel is excellent. There's no compromise between performance and battery life. Well done and thank you for putting the effort into making it.

Everything's great on my end on the latest kernel zram latest beta! Got three days on the last charge with 3 hours of screen on time and had 30 percent left. No bugs, glitches, or freezes or anything.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Michael_Kuhhh:
What does the zRam do ?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kitcostantino:
basically, it creates a swap space to hold more apps in RAM.

In older iterations of android (think 2012 or so), zram was used to keep a couple of apps from bogging down and kicking in OOM (out of memory app closes). on newer devices, the ideology is OP6t has so much extra ram, zram can yield a noticable difference in performance by virtue of keeping more apps loaded in the swap space zram creates.

I am not the definitive source here, but my understanding is that the Beta rom versions have zram implemented, and thus they need the zram version of the kernel.

i stay on stable, so i cant say i have tried the zram version. i doubt its really necessary with 8gb of ram, though.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] drake90001:
Compatible with .15 beta?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Michael_Kuhhh:
Hmmmm could that be why my phone keeps shutting down after flashing the regular kernel (not zram)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Affy08:
If you are on open beta, it's better to flash the zram version. Less complications
