Development Goals:
- stability
- energy savings due to more efficient algorithms (whether theoretical or not is unimportant)
- strictly no overclocking unless approved by the manufacturer or my source base integrates it (also, even if my source base integrates it, expect no support for it)
- no undervolting as well unless the manufacturer approves it since it's relatively pointless IMHO...
- all improvements should require MINIMAL user interaction (e.g. you don't need to do anything except flash the kernel or at the very least use SetCPU or the like to set fixed options)
- stability

FAQ or something like that:
1.) Camera doesn't work!
- Try this fix from Golv here. This usually occurs on older ROMs.
*Latest 20130625_10XX version should solve this without flashing older camera libs.

Could you please expound on your statement that undervolting is relatively pointless?
From my experience, undervolting
1. Improves battery life because of lower wattage (Voltage * Amperage = Wattage). Even with a really bad binned CPU, it can still make a difference.
2. Cooler operation. This means longer component life - especially important as this phone is very difficult to repair. Battery is sandwiched so the cooler we can keep the device, the longer the battery will last. (Battery longevity practices could be a topic of it's own)
3. It's Fun! Haha. But seriously. I love to tinker. How low can you go??? It's fun seeing a 25% decrease in voltage and it still run stable
I really like your approach with the rest of your points though. We should have a stable kernel that doesn't have to be tuned or tweaked at all. This however, only suites the majority. The minority may want more. I'm currently in the process of making a kernel with as few restrictions as possible. Except that I will put a ceiling on the maximum voltage (1.25v for the cpu)) because I discourage overvolting beyond spec.
Anyway, thanks for the work. The One is Awesome!

Should have put a qualifier there huh? Anyways, it's pointless from a no tweaking perspective since undervolting may not work for some chips and could cause more trouble (random restarts and the like) than it's worth. It's fun for a tweaker (like when I did something like that for the N1) but not for someone who's the flash and forget type. :fingers-crossed:
Thanks

If somebody have problems with the camera, use the camera Fix from here:

The bug is due to the old source code, released by HTC
If you are using a ROM based in 1.29.xxx.16 like the most of the new custom Roms flash just after the kernel.
Are the old camera libraries, that works with the Custom kernels.

Some of you might remember me from a time long ago and a galaxy far away!
I built/maintained dagkernel on release day for the Note 1, bringing root+overclock+recovery on day one of release
Well, recently my home was burglarized and all of my electronics taken. I took a very big ol hit that made me a sad panda Along with this stuff was my fancy-pants Alienware M18X laptop (minus the power brick, so they can't use it!) - which had all my source codes and development enviornments on it.
Rather than cry over spilt milk (really, I cried for a week! ) I decided I would re-build my development enviornment and crank out a new kernel for Galaxy Note, which is the most powerful computing device I currently have! (I am developing on an old school core 2 duo w/1GB RAM that sure feels slower!)
So, build enviornment is set up and the first build is done. Which is simply a re-built ramdisk and kernel from AT&T source. Using the newest available prebuilt toolchain from Google. I won't release this version as pretty much nothing is changed. But I wanted to get my dev enviornment up and running A first release with actual, substantial changes should be available within the day.
Support will include 4.1.2 stock ROMs (for the S-Pen love), CM, and whatever else I might support (suggestions?!)
GPU/CPU overclock will be supported, with the separate interfaces for overclocking each via an app. Hopefully I can actually push the app out this time around, it stayed internal only last time (although all frequencies and voltages were changable via boot script)
I took a look at the existing 4.1.2 kernels floating around and noted that most of them neglected some patches I made to Samsung's original source that did some funky things like re-set CPU1 (the second CPU) to stock speeds after toggling it off (for power saving)
As a result, the performance of these kernels is probably not quite what it should be after the first CPU shuts off (which happens almost immediately after android is done booting fully, when the load demand on the CPU(s) die)
Of course, my source will be public as it has been since day 1 and anyone is welcome to source my patches without asking. Viva la developers!
May your Galaxy Note run faster than this pos Dell desktop I'm using real-soon-now(tm)

I will have a first release out shortly. Just testing the impact of mpdecision on cpu performance.
For reference at OC to 1.83ghz/performance gov I was able to pull 9556 on antutu benchmark with performance gov and mpdecision disabled, ~6320 prior to overclocking. GPU is at 300MHz.
With ondemand gov and mpdecision enabled, looking around 8550. Lets try with performance gov and mpdecision enabled now...!
These scores seem about on par from what I remember from the first go-round I don't yet have the configuration sysfs interfaces set up.
Wow u know ure stuff n that really sucked about ur belongings but glad ure back in the community!

Awesome bro. How is the battery life? You going to put this out tonight?
Here is a first version, in TWRP/CWM compatible zip file. It is set to 1.83Ghz/300Mhz OC ondemand by default, with mpdecision left enabled. You should be able to use a tool like system tuner to change cpu frequencies and governors. I did not yet enable init.d support for a script in /etc/init.d to change frequencies on boot. It is on my to-do
This build is for 4.1.2 Stock/TW-based ROMs and most likely won't work on CM. Again, that's coming soon
As for battery life, I really don't know yet. I haven't had the phone disconnected from the computer during development, and this computer is so much slower than my old one I don't dare waste time doing things like that just yet. You guys try and let me know
I am thinking about 4 distinct releases,
High Power 4.1.2/Stock and CM
Power Save 4.1.2/Stock and CM
That way I can make one for balls-out speed and one for day to day use. I'm a fan of speed since I have an external battery charger and 4 batteries.

Seems like everything is running a-ok. I'm using it now Going to test it for the next couple days and see how it runs
Feels a little sluggish to me right off the bat. Tweaking the speed/governor with an app brings it right up to snappiness. Not too bad for a first run on an entirely new(to me) anciently slow computer, though. Only gets better from here

Introduction
Hello everyone! Some of you might recognize me from the Xthermal Fast Charge thread, where I had earlier created and posted unified zips for modifying the stock thermal config file on the Nexus 6P, combining the work of two different mods, namely CTTMod and Xthermal Fast Charge Mod.
Since I was earlier maintaining my unified zips in the Xthermal Fast Charge Mod thread, I have now decided to create a separate thread for them since there is still interest and I don't want to unnecessarily clutter somebody else's thread. Let's get straight to it then!
Detailed Information
CTTMod - Thread Link
When CTTMod was initially released, it changed certain values in Nexus 6P's stock thermal file to raise the temperatures at which the phone would start to use thermal throttling. This change led to an increased overall performance and the phone could be used for a longer period of time without any crippling of performance due to thermal throttling, at the cost of heat. Therefore, after using this mod, the phone would feel slightly warmer as compared to how it would've felt if this mod had not been used, but with higher sustained performance.
Xthermal Fast Charge Mod - Thread Link
When Xthermal Fast Charge Mod was initially released, it also changed certain values in Nexus 6P's stock thermal file to raise the temperatures which prevented the charging current to exceed a certain value (usually ~1500 mAh to 1700 mAh) even though the stock OEM charger was capable of delivering a current upto 3000 mAh. This change led to an increased average current drawn (~2600 mAh to 2800 mAh), thereby leading to a decrease in the time taken by the phone to charge, again, at the cost of heat. Thus, a faster fast charge.
Unified Thermal Mod
Since both the base mods target the same stock thermal file, they can't be used together and using one would override the changes done by the other. In other words, one can only use CTTMod or the Xthermal Fast Charge Mod, exclusively. My unified thermal mod provides a workaround for this by taking the best from both of the above mentioned mods and combining their changes into one file, packaged into a Magisk module/TWRP flashable zip, so that one can take the advantage of both, increased performance due to an increase in thermal throttling temperature limits as well as a faster fast charge.

Important Read-Me Points
Installation/Uninstallation
In case you wish to install the modified libraries directly in the system partition and not as a Magisk module, then add "sysover" (without the quotes) to the zip name and flash it via TWRP.
The zip will abort the installation if you try to flash it on any other device except the Nexus 6P and if you aren't running Android Marshmallow, Nougat, Oreo, Pie or Q.
The zip auto-detects your Android version and installs the correct modified thermal configuration file automatically.
To uninstall the mod, just reflash the zip via TWRP and it will undo any changes it did (whether installed as a Magisk module or directly in the system partition).
General
The mod only works with the stock OEM charger. If you're using a third party charger (irrespective of the fact whether it supports Qualcomm QuickCharge or any other fast charge capability) this mod won't work.
The lower your battery percentage is, the faster your phone will charge, i.e. as the battery charge percentage increases, the current drawn by the phone will decrease. This is stock behaviour.
The mod doesn't change the USB charge current. That is controlled by the kernel.
Regarding the thermal driver, it is preferred that you enable msm_thermal and disable core_control for effective results. However, if doing that causes issues for you (for example, cores don't come online automatically after going offline while using msm_thermal), then disable msm_thermal and enable core_control via a kernel tuning app, like EX Kernel Manager.
If possible, avoid playing games/use performance heavy apps while the phone is charging. Doing so won't cause any issues, but it is preferred not to do so while the phone is on charge.
Disclaimers
I am not the original developer of the base mods used, i.e. CTTMod and Xthermal Fast Charge Mod. I merely combined the two since they couldn't be used together. I take no credit for the original work. Please direct all your thanks and/or donations towards @Robshr and @ravinder0003, the original developers of the mods.
You are doing this at your own risk. I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you are unsure of how to go about something.

Haha, come on now, I'm not far from the Philippines (I'm in India) and I gave it a shot. Jokes apart, I know what you mean man. For us, in summers especially, this might not be the best mod to use on a daily basis, more so if the usage is heavy. In winters, however, it's a different story entirely, and I found this mod really helpful.

Also, you might want to consider a battery replacement if you plan on keeping your 6P for some time. I got it done from the Huawei Service Centre in my area, and the original one didn't cost a bomb at all. After the change, my SOT started averaging 4.5-5 hours (up from 2.5-3 hours).

Yeah i've really considerd replacing it and I've heard its quite cheap. Though last april or so I've heard somebody talking about battery replacement on PH and huawei said that they're running out of "stock" with angler. So I guess I better check it out. I might not be buying anyreplacement sooner or later but I have plans next yr to buy the OP6 or Pixel 2.

Yep, like I said before, it's not expensive, so if you manage to get your hands on one, definitely go for a replacement. Hopefully, some are still available and not out of stock. Also, I'm not too keen on Pixels anymore, seeing how comparatively difficult it is for developers to get stuff working on it + they cost a bomb! That's why I went for OnePlus 5. Had Google stuck with the Nexus line-up, I would've never bought anything else to be honest, but well..

Me too! :highfive: Coming to Nokia, they're definitely upping their game, but I'm not sure about the developer backing it will get vis-à-vis OnePlus; the latter has the best developer backing after Google.

If while flashing the kernel, you selected the overclocked frequencies for your cores, then use the overclocked oreo variant of the mod. If you didn't make any changes in the frequency screen/aren't sure if you're overclocked or not, just use the normal oreo variant and you should be good.
I notice higher temperatures as expected.
Actually my N6P reached 44.5C, are we fine?

Thanks for the mod, no offence.

Yes, that is expected, because the mod increases performance at the cost of heat, so temperatures will be slightly higher as compared to stock. It's been mentioned in the OP as well.
Also, no offence taken, at all. Feel free to use/not use the mod, whatever you feel comfortable with. Thanks for stopping by!

You can use a kernel manager app like EXKM or Kernel Adiutor to check that. If the maximum CPU frequencies for the little and big cluster are 1708 MHz and 2054 MHz, respectively, then you're running an overclocked kernel. However, if they are 1555 MHz and 1958 MHz, respectively, then you're running a non-overclocked/stock frequency kernel.
I know asking for ETA isn't allowed but could you do a fast charge only version for Oreo? I really dislike the thermal mod but would love to have the fast charge one
Hi, I am not quite sure if this is the right forum to ask about that.
I am interested in tuning the performance of my OnePlus X to a maximum level.
I followed lots of the basics which were about tuning the default android install (changes in settings mostly), but that brang only minor changes.
The thing is that I am very happy with the phone hardware, and I do not want to buy a new phone but it is getting annoyingly slow.
I have a skilled Android developer on hand who would be able to install a different OS - if this would be one solution.
Thanks for any tips!

Install yumemichi's lineage Oreo ROM or if you need more customisation install hunfatal RR ROM which is based on yumemichi's lineage source itself.:laugh:
Both are stable and are good at performance.

~~A custom kernel for (most) V20 variants~~
Swan2000 is an android kernel based on the very latest Qualcomm 4.4 CAF sources for MSM8998 (which is also compatible with MSM8996), aiming to bring new features and updates over official kernels, and also improve LGE MSM8996 devices with some extra tuning, fixing and additional features tailored specifically for their performance characteristics and feature sets, while trying to maximize the battery life and responsiveness of those devices at the same time.
Its name comes from a merge between Swankernel(@AShiningRay) and mk2000(@askermk2000), as they were the main heads behind this kernel's development.
__Disclaimers__First and foremost: DO NOT bother official LineageOS threads with bugs if you're using this kernel, only bug reports with logs pointing to the official kernel will receive support there!!!
Now for the usual XDA disclaimer:
We are not responsible for bricked devices, dead SD cards, tactical nukes being set up (with the V20 you never know), alien invasions, google spying on you, or you getting fired because the alarm app failed after you removed all traces of google services from your phone so that google couldn't spy on you.
YOU are choosing to make these modifications, and if you point the finger at us for somehow messing up your device despite YOU being the one explicitly making these modifications, we will laugh at you.
DO NOT expect support on official ROM threads if you are running this kernel. Also don't try to hide it because we will know, and we will also laugh at you.
Your warranty is most likely void at this point anyway, but nevertheless, it is now definitely void if you tamper with any part of your device / software.

__Which V20 variants/models does this kernel support?__
The kernel currently supports the following V20 variants:
H910 / H915
H918
H990(DS / TR)
LS997
US996
US996D(Dirtysanta)
VS995
Those seem to cover every rootable variant thus far, but additional variants can be added in case a breakthrough happens on F800 for example.
__What does this kernel intend to achieve?__
The main goal here is to have a kernel that not only has extra features and improvements, but is also clean and concise, having only features that are truly needed from a kernel that will run alongside a Android 12.1-based ROMs and beyond.
This kernel does have a battery life bias, but will still scale up to maximum performance when needed. Gaming variants basically mean that the kernel comes overclocked by default, no additional tweaking is needed.
__Does it have any features over official?__
Yes, quite a few. The kernel is divided into two variants and their respective gaming modes, here are the features all variants have over Lineage's 4.4 kernel:
GPU and CPU/Cache Undervolt for better power efficiency on load.
Almost no unnecessary debug flags on the kernel for better kernel performance.
USB Fast Charge.
KCAL Control (although not really needed for LOS, other custom roms might surface with the need for this)
Multiple cherry-picks from different msm8996 sources with fixes and improvements to the kernel.
Built with newer GCC toolchains (GCC 12) with optimized inlining and other compiler optimizations for 8996
Updated LZ4 libraries for faster ZRAM
Cryptographic function optimizations, slightly improving the phone's performance when calculating hashes and so on.
The Extreme variant really only has one extra feature over the Safe variant, that being:
Stronger Undervolts (i'm talking about borderline unstable undervolts here, so i really recommend that you flash the Safe variant first).
The "Gaming" versions are basically overclocked variants of Safe and Extreme, which means they also only differ in undervolt levels.
__Are there any bugs?__
As of now, the only actual kernel bug the V20 and G5 have comes down to their insanely over-engineered USB ports. You can't use them as a MacBook by plugging a fully powered hub into them like you could in 3.18 yet.
__Download & Installation__
The folders containing each kernel variant can be found here (use Ctrl+F to search for your phone model and kernel variant, there's just too many versions to neatly organize in folders and such as it would take too much time):
GITHUB KERNEL RELEASES
To install the kernel, it's the standard procedure:
Download the kernel you want for your device
Place it into the phone's storage
Boot into recovery, select it and then flash
Wipe Dalvik Cache (optional, you only need to wipe it if you face random Force Closes, but it is a good practice anyway)
Reboot.
Use AIDA64, go into the "Android" tab and look for "Kernel Version", where it should show "4.4.302-Swan2K-...".
Enjoy the experience!
As usual, we do not take responsibility if you fail to make backups before flashing this kernel, you have been warned!
__Changelog__
Spoiler: Changes done in recent versions:
*********** Swan2000 V0.1-BETA8+ ***********Small release with BCL tweaks for all devices, some msm8998 merges and minor hotspot fixes for G6.
_________________________________________
*********** Swan2000 V0.1-BETA8 [First Release] ***********This one is pretty straightforward: Basically lineage's kernel with all the features and improvements listed above, plus a few additional tweaks that would take too much space to note.
__Closing notes__
If you have any suggestion or idea that can possibly improve the kernel, do not hesitate to share, i will try to implement it when time allows it. If there are any problems that only happen on this version of the kernel, submit a log and i'll try to look at it.
I'll say it again: Please DO NOT bother official Lineage with bugs if you're running this kernel, only lineage's official kernel is supported over there.
___________________________________
The kernel's source code can be found here. It is also shared between G5 and G6!
And last but not least, special thanks to those that helped this major revamp on LGE_8996 become a reality by developing, testing, and even helping things indirectly, the dev community on all three phones had to come together for this:
@xxseva44
@npjohnson
@askermk2000
@thewolfsvk
@ROMSG
@bernardobas
@VortexHD
@Michele_Catella
And many, many others

Might need an additional post at the top later.
First of all thanks! To everyone involved, you guys rock!
A little tangent (bear with me for a while, please)
I had an OP3 before this V20, and like some "developers toy's" received a good attention for some time that phased out and was replaced by many more quickly than his predecessors in my opinion.
Besides SultanXDA Lineage 14 that he customized the kernel+ROM (achieving 6h screen time with ease), the thing that had me impressed was EAS and was beautifully implemented by mcdachpappe in this kernel. That really was responsive and also have some endurance. Other device that I still have it's my LG G4 and the devs ported so many kernels (I used blu_active most of all), but I didn't have the time needed to tweak.
After that detour, I would like to know: (no pressure, complains, just curiosity from my part)
1) EAS it's still relevant? Did you have any plans to implement it? Since the OP3 "has the same msm8996" could it be ported or benefit from this governor?
2) I noticed that you have on this kernel the "basic" governors : interactive, conservative, ondemand, userspace, powersave, performance. Do you consider other addition? Or it's an unnecessary problem?
3) I would love to not need any app than necessary, but to reduce some "image retention" there are many posts to help mitigate this issue, but the configuration it's for some app and trying to replicate in the system settings won't have near the results. Do you have any suggestion?
4) Any recommendations for applications to adjust the kernel? I used many moons ago the Kernel Audtor but the most close replacement that I'm aware it's the SmartPack-Kernel Manager?
5) A feature that always intrigue me in some Sony devices was the ability from stock to limit/manage the battery, "setting a max capacity" to stop charging at determined percentage, theoretically "extending" the life-span. How demanding, and it would benefit our devices this feature?
6) You mention the USB issue. Right now I don't have any hub and would be a nice thing in the future to plug an ethernet cable, be able to use a mouse + keyboard in some situation, and technically the V20 has HDMI out. But in this new kernel the problem comes only to being able to charge with any hub or I didn't get properly what the exact problem was?
7) The "only bug" on my H990DS that I encountered so far it's when I installed the SmartPack-Kernel Manager and in the "Overall Statistics" the CPU temperature are "-4.0°C" (I didn't install this app before with the stock kernel because I didn't needed this app). So how to properly report it?
I can't believe how much more responsive the device is, looks like magic!

1 - No, not really. While EAS was included in this kernel's earlier versions, we opted to drop it from both official and Swan2000 when shipping lineage. EAS just doesn't bring that many benefits, if any, to msm8996 and 8998 devices when the device sources are already well tuned. And that's what we saw by going back to HMP: No significant perf/power difference on V20, G5 or G6, although the results favored HMP a bit since EAS boosted too much.
2 - No other CPU governor additions are planned, interactive can be configured to do pretty much everything you need (our device trees on lineage already have it pretty balanced), and if you can use conservative if a inherent battery life bias is needed.
3 - Lineage 19.1 has LiveDisplay support by default(Settings->Display->Color->LiveDisplay), not needing any kernel additions on that front. Those guides use KCAL control, which is there on the kernel in case other custom roms show up without LiveDisplay. Personally i use a LiveDisplay Color Calibration profile of 94%R, 90%G, 92%B to nearly eliminate image retention on mine, though that's because my display has a green tint ever since i bought it, might not be the same for you. Intensity and contrast values don't seem to affect retention that much so it's up to you.
4 - SmartPack is pretty much the continuation of Kernel Adiutor in case you really need a kernel manager.
5 - It is possible to do that, but requires ROM integration and can also be buggy sometimes (my Xiaomi Mido has that feature on its custom rom and sometimes it simply doesn't charge if i enable the battery limit and it hits the threshold, only charging again after a cold reboot). Since the V20 has a user-replaceable battery, that's not a big deal.
6 - The bug is not on the usb features themselves. HDMI support is perfect, as is OTG, mouse and keyboard as well (and i also think ethernet). The problem arises when fully powered hubs come into play: The phone simply refuses to charge at the same time it's in Host/OTG mode because we didn't fully figure out USB-PD on the new kernel just yet, and as a result powered hubs don't work, though you can still use simpler hubs that don't need additional power, or charge the phone. Since the V20 and G5 are pretty much the only 8996 devices on 4.4 that have this fully-featured usb port, it's hard to conceptualize a fix that doesn't break something else.
7 - SmartPack reporting incorrect cpu temps has always happened in 4.4. Apparently it's a bug in the app because AIDA64 doesn't suffer from the same issue, nor does CPUFloat (although CPUFloat does seem to invert GPU and CPU temps in some roms). I guess that's because there aren't that many Snapdragon 82x devices running 4.4 so most apps focus on 3.18's sensor configuration.

I was aware, but thanks for the reminder, and your settings. When I was using the OP3 in the beginning I disliked very much the punchy color calibration that was used until they released "sRGB" profile that I used ever since (I guess that I couldn't have a Samsung device with their saturated profiles). And I tried to replicate some of the configs but the values don't match if you don't try to calculate. For example I liked this config that I copied from this video description and give me an very soft and neutral color spectrum (too bland for some, and with more time I would search for how to improve it):
Red 256 | Green 241 | Blue 226
Minimum RGB Value 0 | Saturation Intensity 12 | Screen Hue 0
Screen Value 128 | Screen Contrast 128
The color values are really straightforward, but "Minimum RGB"? The "Saturation Intensity" it's separated in 2 distinct values like "Saturation" and "Intensity"? Do you understand the difference?

No problem, I was just mention because my ex-wife had a Pixel XL and I bought to her this USB Hub (UCN 3273) and everything worked (except HDMI because Google intentionally disable HDMI out just to sell more Chromecasts) including PD charging. It was used with ethernet (because a real gigabit connection beats many wifi speeds and consistency, and spots with bad coverage) and even an external USB mic to make video-calls (that without powering the HUB won't work). OK if this features could come to the device, until then no need to rush.

Ok, I didn't know. It's better to know than make trouble unnecessarily.
I remember reading about low volume on audio recording and decided to test on both OP3 and H990DS with Audio Recorder (M4a +48kHz +256kbps + stereo settings). Both devices recording the same initial 20s dialogue from this video at the same distance from the speaker of my computer but very different results.
I even analyzed in Audacity on the computer and it was indeed not only much lower, but was mono instead of stereo.
How can I help you guys properly identify this problem?
Thanks again!

Minimum RGB is pretty useless, it was supposed to deal with the black levels (in essence, how dark should the darkest pixels be on the screen) but never seen it do anything useful on any of my phones, OLED or not.
As for Saturation and Intensity being separated... "Saturation Intensity" is just "Saturation" on LiveDisplay, while "Intensity" on LiveDisplay is the same as "Screen Value", which dictates the overall brightness of the screen's pixels (just don't go too far on this one, or else you'll get overblown whites, also balance it with contrast and you get a nifty max brightness boost for free).

It might come at some point since we really want to fix every major hardware feature of all three phones, though it's one of the peskiest issues to deal with on the kernel side since we have 5 or 6 usb drivers that communicate with each other.

AFAIK that's a known problem on AOSP roms as a whole (happens in 3.18, happens in 4.4, not kernel-side), mics on V20 and others just don't work as intended compared to stock. It's on the list of things we're gonna look at, but it's not a priority right now because we're trying to sort out Bluetooth in order to bring Lineage 20 in.
Once we start debugging the mics, i'll see if i can get one of our rom-side devs to approach you with more info if you're still available by then. Thanks!

Yea in regards to the mic level, this has been a known issue on the v20. However i was not aware of it recording in mono, that is very odd. The level issue is mixer path related, but the mono recording, i'm not too sure. I will admit, it may be a while until this issue is fixed as we're heading into los 20 and getting that ready. But this will definetly get looked at. Could you grab logs of when you record? I wand to see what the audio hal is doing and how it sets up for recording.

Since I couldn't download the latest build because the page error 502, I clean flash 2023-04-23 build and only install the Magisk so I could get an dmesg and the Recorder app mentioned before.
Have 2 sets of archives, the stock kernel and the Swan2000 with logcat and dmesg.
If I can provide more help, please just ask.

Those are G5 and G6 models. This kernel supports all three LGE_8996 phones, we just separated the threads for each of them.
@AShiningRay
I didn't see anything explicitly on this thread or in the github page, but it's BCL implemented on this new Kernel or it depends also from the ROM?
@xxseva44
Was the logs that I send any useful to help diagnose the audio recording issues?

BCL is enabled by default on all 4.4 builds since it's nowhere near as aggressive as 3.18, but you can disable it from userspace but it requires root... though i don't really recommend doing that.

Ah yea, so far i haven't found anything odd. If possible, can you reboot, record something and then send the logs right after? It'll help with locating the issue if that's all that audio did the entire time the device was on.

I'm sorry, but I didn't fully understand what you requested me. So let's recapitulate:
1) Reboot
2) Record
3) Log (Only logcat or with dmesg as well)?
Little off-topic: I noticed a strange behavior last night, when for the first time I tried to record an video with GCam (if you/anyone have another version, build to suggest, I'll be grateful) and no audio at all. So I opened the stock Camera and the audio was loud and clear. And with the stock audio recorder was also very low volume as with the other app.
Are those things even remotely related?
Thanks!

All logs, grab them via adb right after running the recording. As for the wonky audio levels in different apps, yes they are related. Something does not seem to be right in terms of the mixer levels so I'll need you to log all the apps that behave weird so i know what routes to look at.
So far so good. I've only had one random reboot and that was on the Safe kernel. I'm now on the Extreme kernel and no issues so far. My H990 definitely doesn't get as warm compared to the stock kernel and it still looks and feels snappy.

Ok I'll do probably today or tomorrow and post it later.
Since I don't play any games anymore on my phone since Clash Royale many, many years ago, the most intensive thing that I do it's occasionally video-calling via Telegram FOSS. But let me tell about my history with this V20 H990DS
I bought this device used, and the seller said that the battery needed to be replaced, and randomly it gave me green-screen reboot messages when below 30% and the thermals wasn't great because it was the end of summer here in Brazil. Since everywhere that I searched about buying new LG batteries anyone tells that it's hard to find a real original and reliable I decided to try this one from Aliexpress, and also ordered some copper shims (0.5mm and 0.6mm) to put thermal paste and improve things. And a 128GB SDcard since it was cheap now (compared to years ago... I tested with H2testw and it works perfectly)
So the battery arrived first, and even before it arrived I installed the Lineage 19 and with the new 4.X Kernel it almost never gave me more green-screen reboots, but few random reboots when below 35%.
With Lineage 18 + SwanKernel Extreme gave the most stable scenario but only one time I did try to video-call with Telegram and it went stable, but slow (probably due underclock, maybe?)
But last Friday using the new battery I tried to video-call through Telegram some relatives that live abroad, and with only 5 minutes of calling it rebooted and was warm-ish? So the copper shims arrived early that week and I decided to do the thermal mod this week.
With the 0.6mm it pressed the LCD giving a darker spot, so I decided to replace with the 0.5mm, put new thermal paste and try again... So no dark spot on the screen.
I installed Telegram on other computer and tried to call and test the V20, but it still reboots after some time, but the strange thing it never reaches 62 or higher.
I tried the CPU Throttling Test to test the thermals and it barely reaches 60 with the Extreme+Gaming or with only Extreme as well.
So after all of this, I remember that H990DS have the reputation for drawing a lot of power:
1) Even a "compatible non OEM" battery can't provide what this device demands in terms of power consumption?
2) Having a dual-sim gives me freedom in terms of separate personal-work calls etc and not having to carry 2 phones. Could a dual sim card adapter could be a better approach?
3) There's a chance that this H990DS motherboard it's problematic/defective somehow and replacing with another H990DS would fix things (or even a H990 non-DS with that dual-sim adapter)?
4) The random reboots could give some useful information somehow for you devs? And how the best way to collect it?
5) Are video-calling that demanding, even if it don't reach the same temperatures that the pure CPU stress?
6) Any tips, suggestions?
Thanks!
PS: @xxseva44 sorry I couldn't give you the logs, but the instability/problems here are taking much more time that I initially planned.
