[KERNEL][PORT] Sultan Kernel for Android 11 [February 3, 2021] - Google Pixel 2 XL ROMs, Kernels, Recoveries, & Oth

Hi again Sultan Kernel does not support Android 11. So with permission from @Sultanxda, I decided to port Sultan Kernel over to Android 11.
There are a few things I should say about this project so users are aware. I currently do not intend on maintaining this kernel after Sultan has released his official kernel for Android 11. I'm yet to have any issues with stability. Your mileage may vary.

What does the removal of the panel brightness limit mean?

By default, Google have limited the brightness of the panel to a value of 225 out of a maximum of 255. This removed that limit and allows the device to utilise the panels full brightness

Be sweet if you made a P version of this same kernel!

I do have similar builds available for P on my GitHub releases page. The builds for P are unified with Q kernel sources and contain the same features as the Q kernel.

Will the top one work on P

Is this a stable feature?

Sentheb3ast said:

Click to expand...
Click to collapse
Yes it is 'stable' and is used in other kernels like ElementalX by default. The only negative that I think could arise from this is an increased chance of experiencing screen burn in when utilising that high brightness a lot.

Can you add zstd compression for zram?

neekless said:

Click to expand...
Click to collapse
No, as I don't believe the compression algorithm for ZRAM can be modified from within userspace. The concept is to stay as close to Sultan's kernel with only additional options for those who want them. The core kernel should remain the same. Besides Simple LMK already does a fantastic job of memory management IMO.

New compiler benchmark results from hackbench — a tool (compiled executable here) that aims to solely benchmark scheduler and pipe performance. Keep in mind that you'll probably never see an improvement in real-world scenarios.
TLDR: GCC 9 > GCC 8 > Clang 9.

battery charging limiter:
open
Code:
/sys/kernel/charge_levels/charge_level_ac
or
Code:
/sys/kernel/charge_levels/charge_level_usb
and write the maximum charging current you want (measured in mA). Obviously the -ac file applies the limit when charging via the wall charger, the -usb file when charging via USB. 0 = stock settings.

I have no idea. I'm still a beginner in the world of OPO's ROM's. If AOSP-CAF uses Sultan's camera, my guess is that the whole kernel will probably work. If you try, let me know the result.

Autosmp was developed by mrg666.

Which thermal driver? And a way to use sdcardfs instead of fuse on sultan's los? And thank you for sharing this with us.

Sultan's thermal driver. To use sdcardfs on ROMs that normally use fuse, just add ro.sys.sdcardfs=true at the end of your build.prop and reboot.

Yeah no problem with the video, asking for permission is right when you need to mirror a file, or publish it somewhere etc. To show my work in a simple video is totally fine!

[SIZE=+1]Notes[/SIZE]
WARNING: Latest firmware is now required and enforced starting from 20190214 build. Make sure you flash firmware once BEFORE the ROM or you'll get error while flashing. You can find the latest firmware on my webserver, the OSDN or AndroidFileHost.
Firmware requirements:
20190804 and newer: Pie 16.2017.1906.056
20190526 until 20190712: Pie 16.2017.1905.053
20190505 until 20190513: Pie 16.2017.1903.050
20190312: Pie beta 16.2017.1902.037
20190214 until 20190223: Oreo 15.2016.1901.339
NXP TFA98xx amplifier support won't be fixed until I find a working OSS variant for it.
Don't ask me to ship prebuilt audio blobs together with prebuilt audio amplifier from TheRagingBeast, since it's a pretty bad idea to use prebuilt audio HALs. If you want it that bad, use custom kernel that has the required commits and flash the amplifier zip (please find it elsewhere and don't share it here, sorry).

Sorry man,I forgot to say if "ROM supports screen stabilization", or maybe later on Xenon HD you will enter the feature

@krasCGQ feeling very good to see a developer like u is working for this device.
Your ROM is smooth!
BTW, if u don't mind, can u kindly port the MIUI10 ROM for our device?
Or, any custom skinned OS.
As, we are bored with the stock Android looks.
(There's a stable miui10 port already by Sagar Makhar, with the SOT of 8hrs~9hrs approx!)
But, we need updates!

Ok.
Is there any custom ROM available , which has something different in looks ,specially the status bar.
(I really become irritated whenever i see the AOSP status bar, this is so much ugly! yaak)

There's no rom with such kind of feature... U can always try substratum... it's really good for customisation..

Please please can you set default antibanding to 50hz and there is a problem in vedio recording sound in ever rom including this one

Of all the pie roms i have used...this is best one as i am getting more than 10hrs of SOT..So kudos to developer for that...but it will be more awesome if it gets basic custom rom features like...long press power for torch,staus bar modifications.
And theming is also not working...acsent colour ,dark theme or black theme doesn't seem to work...i do understand it's experimental but it will be really nice to have these goodies

As I remember:
1. Long press power for torch is exist and working.
2. As I said in OP, it's still on development.
3. If it doesn't work on LineageOS, it doesn't either on XenonHD.

I'll be the first. Just formatted my device and rooted it, first kernel im going to test!

Wow, very interesting changelog, will be interesting to see how it performs and what others think!
Conflicting decisions between kernel devs it seems on some features, like ZRAM for example.
Looking forward to flashing

Looking forward to flash, there's no klapse support right?
Edit: Damn this kernel is snappy AF ?

Congrats on this release!

Finally arrived! waiting for it since I know you are about to build one for op7pro.

/* Notice */
Both OnePlus 7 and 7 Pro is supported.
Only OxygenOS is supported, but it is likely that the kernel will work with other ROMs. Though you may encounter minor issues.
Feel free to tip me which commits are needed to fix other ROMs.
Android Q beta is not supported and I’ll not spend my time adding support for it.
Do not ask for premature Android Q beta support.

Version Information
Status: Stable

Keep in mind this is early build and many los features are not merged yet do not report those as bugs as they are not device specific and will be resolved
Also here are some screenshots
Also big thanks to everyone who supported this and other projects since lineageos 15.1 since i do this in my free time and donations help offset server cost and get me coffee

Wow, you just keep this device alive. Cant wait to try this Rom(im currently downloading...) Will report in a few days how it is

Holy moly, that was real quick. Thanks for this ROM! Do you think you could fix the microstuttering that sometimes appears on LOS 17.1? I see you have an EAS implementation in the works but only you know the real status of your tree.
Alternatively, could you provide a no-op performance profile so we can tweak the interactive governor through a kernel manager? When I change my governor settings for my custom ones microstuttering goes away until they reset to default after a while even if I enable apply on boot, and the default performance option is janky when doing anything more intensive than scrolling a webpage or through the system UI. Sometimes playing games is impossible because it runs smoothly but randomly jumps.
Again, thanks for your ROM. We are blessed to have a dev like you working on this old horse

So far ROM is awesome smooth and fast ,only problems for me at least:
1-brightness slider
2-calls problem can't hear or talk and can't record in such apps like WhatsApp
Thx for ur awesome works so much appreciated

Hi,
Did anybody try to dirtyflash from 17.1? I had no luck so far...
And again, big thank to Ivan, for the rom and keeping device alive!!!!!
thx

I don't know if you mean the same thing, but at least Pokemon Go "jerkiness" can be completely fixed by changing GPU powersave mode from "coarse demand" to "always on".. But you need some adjustable kernel like Morokernel to be able to do this, and Moro is not very good with recent LOS versions.
I don't know what the issue with "coarse demand* is.. it turns off GPU power after 100ms of idle. That certainly shouldn't happen during gameplay when there's constant movement on screen?

Thanks for responding. Changing to always_on does help a little but it makes the phone MUCH hotter...or is it my idea?
The phone is hotter and it still stutters, I tried changing the I/O schedulers to less intensive noop and tweaking the interactive governor helps but then it resets itself back to stock settings no matter what I do. But no matter what, there is always at least a bit of microstuttering. It is ruining the experience on this otherwise perfect ROM.
Also the custom kernels are using a different kernel/binary blob base that doesn't work with this ROM family anymore. I personally don't want to delve in the headache of merging commits and fixing build failures, it means downloading yet another kernel for yet another SoC and my space is kinda limited right now because I already maintain a device.

Hmm. I'm actually currently on FloydQ rom. It is very smooth with Moro and this "always on" mode. Battery use is very minimal, phone does not get hot.
FloydQ is using the older code base so Moro works. But earlier I was using some older LOS 17.1 beta with Morokernel and it was smooth. The later versions (with newer code base) stuttered..
Hmm.. perhaps there is some bug causing entire device to halt for over 100ms? Then coarse_demand mistakes this as idling and powers off the GPU, making things even worse.

I can't see call screen when someone calls please fix this

As it says on the main post, it's pointless to report a bug without including:
a) Logcat
b) proc/last_kmsg (or proc/kmsg)
c) data/tombstones
d) dmesg
as he can't possibly recreate every issue.

Thank you !
I will test with NikGapps

please someone upload it on sourceforge ((((

I am switching to another ROM and flashing echofix

Wattsensi said:
Does this ROM have all the bugs and instability older Lineage ROMs had, or it works as a daily driver? Apart from the fixable echo problem, do calls work well? I am considering switching ROMs to instal ThundeRStorms Kernel if I can't solve this issue from userspace. as a bonus I get EAS.
Click to expand...

Well.. I'm probably the wrong person to answer, as I have never encountered the echo or volume problems on LOS either. And I use this as my work phone so I call quite a lot.
But still yeah, FloydQ feels very stable. I think it's mostly binaries moved from the S9+ rom, as it has all Samsung proprietaries working (like VoLTE calls).. I assume echo cancellation as well. And it passes SafetyNet out of the box, you don't necessarily need Magisk to run bank apps etc.

Well, I flashed Resurrection Remix and indeed, the microstuttering is gone! Thanks for the recommendation.
EDIT: The culprit seems to be the N935KKKU4CTH1 rebase, running a ROM previous to their inclusion makes the problems disappear

Thanks for your work
Working fast and snappy on taimen running ProtonAOSP 11.4.0

Is anyone successful in flashing on crdroid? What's the experience like

Flash in walleye run 11.4 proton OS . Boot fail. Auto boot to bootloader
Show notify yellow at the bottom: ERROR: BootLinux Failed: Not Found

Can i use this on Android 10?

Did you flash the kernel correctly? It appears that your boot image is corrupted.

No, only Android 11 phones with the latest firmware are supported.

Download your kernel.
And flash via twrp

It appears that I had removed important dtb files which made the kernel unbootable on walleye. I uploaded a new build to (hopefully) fix the issue. The new build should be called "Sultan-kernel-plus_20210418-fixup.zip".
EDIT: It's fixed and is safe to flash.

Yay... It boot now. But do u know why it same issue like other kernel ? (kirisakura, sultan old version,...) .
The issue is: when restart, the boot amination very very slow. Some time when the screen of press power key to turn on phone it take 3-5s to open (sometimes not usually) .

New build is up with some original commits. Nice!

any settings for rgb to eliminate the yellowish from white?

Newwwww build

@Kaz205 I've been following your github repo for a while and there was a period of time where you used PELT and is no longer using it. Just wanted to know what are your findings regarding PELT?

I initially switched to PELT in hopes of lower jank. However I switched back because it turns out that PELT breaks live frequency stats and that jank is more or less the same as WALT with some proper tuning.

New build is out with lots of cool changes!

May I use this kernel for 10?
