@fereidooni was right - freezing and reboot if play video (Youtube Music in my case).
I am back on 1.4 :good:

[Kernel][grus] Kowalski Kernel [ beta: XXX - stable: r1.9.3 ]
- Thread starter pengus77
- Start date
Tried flashing the beta on phh v115. Freezes pretty often in Chrome, forcing a restart. WIll try wiping davlik and cache
Yesh, the beta has a problen with memory heavy graphics operations.PPlease don't use it and get back to stable as noted in the previous posts. I'm working to fix this for the next beta.
Pleased to report that stable is working stable
Sooo, tracked down and killed the video-reboot-freeze-omg-help problem (probably). Works for me here, so it should work for you too.... hopefully...
Anyway, still getting the super-duper memory optimizations, so enjoy this one and let me know if it's release-worthy
Grab it here or in the second post or on github... you know the drill

Here to report after 30 minutes of usage of the latest beta:
Everything seems to work perfectly as stable, but, the video issue that freezes and you need to reboot still there. Rolling back to stable for now.
Edit: I'm on the July build of Pixel Experience GSI.

Argh, the link in the release post pointed to the old beta. My fault guys. Make sure you're running 15b and if you downloaded from the link in the previous post, please re-download it. My bad. Apologies.
By the way, I've tested with local videos, youtube, prime, netflix and web videos. All is good here.

Yeahp, seems all fine here! Tried to record a video, playing a vid on YouTubeVanced, playing a huge vid that caused the bug the other day and everything is ok. Thanks for the update :good:
Kowalski Kernel b1.5c
And here we go again. New day, new beta release.... getting closer to a stable imho...
Anyway, reintroduced the brightness fix that I disabled a few ago because I was on 10.3.1.0 vendor (no bug there). Installed latest EU vendor and bam! got hit by the bug. So now it should be fine (thanks @okitavera for finding this fix upstream). You can grab the beta here (this time the url is right LOL)
Let me know how it goes. Have fun

hahaha yeah it's insane to follow all the people using different vendors / firmwares / basebands. It's like chasing a rabbit down a hole. Now I get why lineage sticks with a firmware / vendor set and never changes it
Yep various vendor and firmware = pain in ass. That's why we put crDroid in the OP link on the latest from China Developer ROM - 9.7.25.
actually the pain are comes from the china developer ROM. How ?
1. They significantly changes some implementation in their app/frameworks, or just "android".
2. But... instead of improving their logic on the android levels, they decided to modify the kernel and of course, the glues between those layer, or we can just says "HAL".
3. Since unofficial developers like some kernel hackers around XDA (maybe @okitavera too) is using an outdated kernel source, the "android" will runs incorrectly on some cases, because the HALs is not perfectly compatible anymore.

it's quite easy.
tell everyone to use stable version, both the users and xda developers. which is impossible, because their friends will says "hey I'm using ported rom from meme.eu because of course is it".
or
either drop all links related to miui china developer, so anyone in the internet can't download it, and focus on the stable version, which is impossible too.
or
tell someone on the xiaomi that they should push their regular weekly updates on their github, which is...yeah, frickin impossible and too egoistic ?
Or I keep shouting for a serious rom developer to partner with that helps me build and test a proper vendor for a non gsi rom. At that point we're good to go and we decide when to update the blobs.
yeah, it's 50% of my 1st point.
and that's the most realistic way, especially since your kernel already focusing for aosp gang ?
I had with 1.5c after night 7-8h only 1% battery consumption. :good: All switch on like LTE, BT, data, wifi,... wow
woahh really ? that so freakin awesome , will try it asap
thanksalso the dev :victory::victory: big thanks

25Ehm... hello everyone
Our phone is quite a little powerful beast, but Xiaomi really made a crappy job on optimizing it, right?
After unlocking the bootloader I felt the need to go back to my roots and get my hands dirty to fix the wrongs in the kernel they released. The phone felt slow and heavy, the battery barely lasted a day. I use my phone for my job and I need to be snappy, stable and last way more than a day. So I started tweaking, digging and experimenting and the result is this kernel that I'm releasing today, in an attempt to make our MI9SE a bit better for all those people who actually use this phone... as a phone...
This kernel is GSI / AOSP only. Don't flash it on Miui based roms unless you are suicidal or want to lose some features, in which case you're free to do as you please and I'm free to ignore your posts, right?
There will be, from time to time, experimental/unstable versions that I release for public testing (usually they're not harmful, but... ehm.... ok you get it) so watch out for the second post if you feel brave and want to be on the bleeding edge. Official kernels are released when the beta testing phase is done and 100% of the feedback is positive.
Don't ask for ETA or you'll be fish slapped... badly! Ignore this warning only in case a nasty bug slips in the release, then you can fish slap me
Ok, enough talk, let's get down to business now.
Features
* Compiled in release mode (all debug stripped)
* Removed all auditing
* Disabled modules support to avoid interference from Xiaomi vendor
* Battery friendly, performance aware
* DT2W support. If disabled the display and touchscreen will power down
* 3G modem small optimizations
* K-Lapse 5.0 support (thanks to tanish2k09 for this awesome piece of code)
* Flicker Reduction via heavily modified Exposure Adjustment module from Sony
* Boeffla Wakelock Blocker pre-configured to block most of the bad boys
* BFQ and CFQ I/O Schedulers
* Adreno Idler support (your gpu will thank me)
* Westwood TCP congestion algorithm enabled by default (and a lot more enabled)
* Support for NTFS (read only)
* Support for F2FS
* And loads more... yeah just ask or check my github
Q & A
Q: Battery !!! Why it's so baaaad ! My phone doesn't sleep !!!
A: Well, don't get it badly, it's not really my problem, is it ? 99.999% is an app you have installed that's preventing deep sleep... go ahead and install BetterBatteryStats, check the Partial Wakelocks and se what's killing your phone. Have fun
Q: App X crashes ! OMG all my data is gone !!!
A: Read again on top, not my fault, sorry. I try my best to give out a stable kernel, but "**** happens" and i can't control it...
Q: I get tons of bsods, my phone doesn't wake up from sleep, it freezes and omg... it just exploded !!!
A: No dmesg / logcat, no party. And please don't post messages like those in the thread if you're not ready to attach a log to the post.
Q: When will you enable gpu overclock, road runner speed mode or wile e. coyote immortality ?
A: Never... on a second thought... maybe... who knows ?
Q: When will you release the new version ? It's a week we're using the old one !!
A: Is it stable ? Then please allow me to fish slap you with a huge trout !
Downloads
All downloads for Kowalski Kernel will be linked in the second post AND in the thread when a new version is released and a changelog will be filed accordingly.
The downloads are labeled as "kowalski-XY-grus" where X can be either "r" for release or "b" for beta. Y is the version number. Eg: kowalski-r1.4-grus is a release, while kowalski-b4-grus is a beta version.
Source will be pushed to my github about 2 or 3 days after a release (or before if I'm not careful), to make sure that no major bugs are introduced in the public repository. You can find the magic code here
This kernel can be compiled with any clang 4.9.x that supports the aarch64-linux-gnu target, so if you want to compile it by yourself you'll have either to build your own toolchain, or use one of the many prebuilt ones (for example from aosp).
Please don't rip-off my work. Please don't kang this kernel. Please don't c&p from my github without proper credit. I'm a nice guy, but i will report you.
Little code of conduct for my threads is necessary: no drama, no OT. Oh and please don't message me on Telegram privately when we have this awesome platform where everyone can benefit from the Q&A.
Thanks
* Okita for the awesome job she made on the base kernel cleanup (this kernel is based on one of her first releases)
* Linus, well, for the linux kernel
* francescod for taking the risks of testing possibly harmful pre-releases
* qualcomm, because codeaurora is awesome!
* osm0sis, the one who allowed us mortals to provide flashable kernels without pain
Oh, I was almost forgetting... on a side note... i'm not really responsible if you decide to test it and your phone melts... right ?

Last Updated 2019-09-1315Kowalski Kernel 1.9.3 Release
Hey hey,
new week, new release. This one has been in the works for a loooong time actually (go look at the dev branch on my github to get an idea) but it's really starting to work as I wanted.
Brief recap of the changes between the last public beta and this one:
Version 1.9.3 release - Download here
* Implement display idle states and expose sysfs nodes to manage them
* qcacld-3.0: Add sme_power_save_api.h include
* Add toggle for disabling newly added USB devices
* sched: don't allow userspace to boost at will
* defconfig: disable misc device and rework a bit
* kernel: implement vDSO64 and vDSO32
* spi: increase timeout to make FOD more reactive
* Bump Linux version to 4.9.192
See, lots of cool things in there under the hood. First, as usual, lots of wifi love... second, FOD speed... third, compatibility with crdroid FOD... and more, lots more....
Let me know how it goes while I keep working on my lineage port. It's going to blow you away but hey, for now I keep it only for me and few selected testers. Want to give it a spin? Drop me a PM and I'll send you a link or a telegram message.
As usual, have fun !
-13Kowalski Kernel 1.8 release (moar battery lovah)
Hey guys, this one was a blast. Had to revert all the updates to the wifi driver because they only caused problems and a bit of drain. I'm working on a complete rebase of the kernel with really minimal Xiaomi patches and full Qualcomm opensource compatibility for wifi and audio. It's going to take a bit of time but it will be here for the 2.0 release (no ETA or be fish slapped!)
Anyway, the changelog is quite long and techy, so in few words: MOAR BATTERY LOVAH! Finally getting below the 130mA for idle screen drain and the race-to-idle code has been improved vastly. Included the awesome ZEN I/O scheduler (try it if you please) and a ton of patches to memory and various timings. Also, removed a ton of debug printouts from the whole gpu/drm subsystem. Next will be taking care of the qualcomm battery (spammy as hell too).
Oh, was almost forgetting, hacked my way through the VTS/VINTF logic and found a little loophole. Exploited successfully and now the kernel is compiled without modules support, profiling, auditing and tracing. Way smaller, lots lighter.
Version 1.8 release - Download here
* reverted the update to the latest wifi driver
* disable ssbd mitigations
* mm:compaction: raise priority
* kernel:sched:fair: align periods to our kernel config (100Hz)
* techpack:audio: remove compat code
* mm: page-writeback: tune values for better memory handling
* kernel: nasty hack to bypass VTS/VINTF checks
* defconfig: disable AUDIT,PROFILING,TRACING and MORE...
* kernel: build with -O3 optimizations
* defconfig: re-enable BFQ as default scheduler
* block: add zen scheduler
* binfmt_elf.c: use get_random_int() to fix entropy depleting
* net/wireguard: add wireguard
* PM: devfreq: Use high priority workqueue
* cpuidle: don't disable cpuidle when entering suspend
* gpu:drm:msm: convert all pr_info into pr_debug
This one is the result of 9 private betas.... it should work for you too LOL
As usual, have fun (but not too much)!

All the kernel tweaks can be edited as usual with any kernel management app (EX, FK, etc...)
About the Flicker Reduction system, if your ROM doesn't support it or if you want to tweak it a bit and you feel adventurous, you can play with these sysfs endpoints
* /sys/devices/platform/soc/soc:qcom,[email protected]/msm_fb_ea_min (the minimum amount of exposure added)
* /sys/devices/platform/soc/soc:qcom,[email protected]/msm_fb_ea_enable (kinda self explanatory, isn't it? 1 = enabled, 0 = disabled)
* /sys/devices/platform/soc/soc:qcom,[email protected]/msm_fb_ea_elvss_off_treshold (the brightness threshold under which the system is enabled)8Kowalski Kernel b1.8c
Hey hey, just finished another round of tests but this one will be considered a beta for now until I get some feedback.
Download here
* Updated wifi driver to latest caf tag LA.UM.7.8.r1-06700-SDM710.0
* Disabled SSBD mitigations, useless for our phone and quite battery and performance hungry
Hope you like it as much as I do
Enjoy!
