[KERNEL] [2.6.32.24] [HAVS] [BFS] [BFQ] KiNgxKernel #11/#11 "Con is an Artist"
I DO NOT have an HTC Evo, but would LOVE to have one for development, and am saving for one. Bear with me until then I just wanted to say thank you to the few who have donated. I am almost there, any help is appreciated!!! I plan to have my HTC Evo fairly soon
DO NOT FORGET TO READ THE ENTIRE POST ON MY SITE, THERE IS IMPORTANT INFO
So, just as the name implies, this is an Evo kernel with SVS (Static Voltage Scaling) & HAVS (Hybrid Adaptive Voltage Scaling.) A huge thanks to estes for the havs code and raven for being the first to implement it into the nexus kernel. What this does is provide SUPERIOR BATTERY life with stability to boot. Just flash the .zip in your favorite recovery image. Enjoy and post any bugs with a logcat please.
This is compatible with any 2.2 Sense ROM
Code:
Also, a little info on HAVS and AVS:
The purpose of HAVS is to minimize the power used by the CPU by determining
and setting the optimal voltage. At the same time, the maximum voltage by
which HAVS can scale to is fixed to a specified voltage depending on the
CPU frequency in order to prevent scaling to a higher voltage than what is
normally used at a specified voltage. The optimal voltage is actively determined
for each frequency and temperature. HAVS actively adjusts the CPU voltage as the
CPU frequency and temperature changes.
Code:
While we are at it, some info on BFS:

I have full adb. I didnt have it when i upgraded from previous king kernels. Had to do a full wipe. Reinstalled rom and installed kernel before rebooting. adb works perfect. full access.

BFS Changelog
Kernel #11
- HAVS is now OUT. We are not currently using it
- Using SVS for voltage regulation at the moment
- Battery life should be great now
- I forgot about an awful lot of longs and ints that will overflow on 32 bit now with u64 deadlines. Fix them.
- Add some macro tidiness
- Make sched_clock sanity checking robust and standardised, using jiffy
difference as upper limit, and use nominal 1us when difference cannot be
trusted.
- In layman's terms these are all MAJOR fixes to his BFS scheduler
- These fixes will provide a performance and stability boost
- Higher clockspeeds are more stable!
- More I will add
Kernel #10
- Performance boost!
- More stable due to BFS overhaul
- Patched up BFS scheduler to BFS 330
- Patched in *NEW* BFS TEST patch that applies over 330 (from CKolivas himself)
* Major overhaul of queued changes
* Micooptimise multiplications/divisions to be shifts where suitable
* Drop the "skip_clock_update" concept as we update the niffies each time we
update the rq clocks, thus we want to update it more often
* Add a local last_task variable to each runqueue which keeps a copy of the
last non-idle task that ran on this CPU. Use this value to determine that a
task is still cache warm on this CPU even if it has run elsewhere in the
meantime. This improves throughput on relatively idle systems with >2 logical
CPUs
* Change SCHED_BATCH tasks to refill timeslices and reset deadline every time
they're descheduled as they've been flagged as latency insensitive, likely
fully CPU bound tasks. This should decrease the impact running batch tasks
has on other tasks
* Bypass rechecking deadline when we know that prev will run again in schedule
* Change all deadline accounting to use nanosecond values
* Rework try_preempt
* MUCH MUCH more check my patch code if you please

And yeah, I haven't a clue what that is. Lol

This is interesting... any more details?

YUP! should have no issues

If one was to push this to their device on top of whatever custom kernel/rom running.. would things start to get messy?
whats the best recommendation ?

Thanks for the quick reply. I'll wait until you put it in. Will look forward to updates on this.

ok guys kernel is live =)
let me know if you have any other questions

I'm done playing for the day but I'm def keeping an eye on this thread. I can't wait to see some real world test results. I have a feeling this thread is going to blow up by the time I get up in the morning.

While I would absolutely love HAVS, I also don't want to lose the modifications in netarchy's kernel with the FPS cap unlocked. Any way you could possibly integrate that into your kernel?
An update.zip would be grand, too.

I have netarchy kernel 4.0.3a with Fresh 3.1.0.1... can i simply flash this over it?

Works on Official CM12.1! Thank u DC

No update?

just tried this kernel and seems great (much snappier than stock cm)... only issue is cam does not work

Great work OP, but same here, camera FC all the time, even with different cameras =(

Hey, very nice kernel with lots of options and features! However, like the others above, the camera says it is busy and closes (motorola app, but should be the same with other camera apps). The torch (flashlight/flash) also does not work, probably same problem as with the camera. Could it be because of your modification of torch power by 20ma?
Tested on cm12.1
Cheers

Camera doesn't work. Torch is completely removed. Are you actually going to update this?

Locking this one, until I make a fully working zip.
Links will remain and users who want to give a try can go ahead.

Installation Instructions​
If you're updating from previous versions of Ethereal kernel or flashing a custom kernel for the first time
❯ Flash kernel ZIP -> Reboot
If you've flashed a different custom kernel before but would like to migrate to Ethereal
❯ Flash boot.img of your ROM (located in root of ROM ZIP) -> Flash kernel ZIP -> Magisk (optional) -> Reboot
The kernel ships with stock vibration patterns by default. If you'd like to switch to the modified one, simply add the keyword modvib to the file name before flashing (e.g. EtherealXO-30.0~Deity-GCC930-Mido-20200825-modvib.zip). Once this is done the ZIP MUST be flashed from recovery instead of through other means such as FKM's flasher.

Normal USB charging current is 500mA. This is increased to 900mA.
This is not related to Quick Charge.

NOTES:
*This kernel has been designed with stability and performance enough to get you a
good battery life.It has been specifically designed for normal app usage and multitasking.
System-As-Root support:This has been provided so that the kernel is compatible with Android 10 roms that
require System-As-Root to function properly.Use the NO_SAR version if you are on a Pie rom, or use the SAR version
if you are on a Q rom.
*Thermal issues have been somewhat mitigated.Note that the values present in thermal-engine.conf and the dtsi
files are marked EXPERIMENTAL.According to tests performed,temperature on daily usage has been reduced.
But due to reduced values,GAMING will partially suffer due to little/random FPS drops.
In my testing,playing games like Crazy Taxi,various indie games,Rebuplique,GTA SA etc. was smooth,but a *gradual* (not sudden)
rise in heat was noticed.Others complained that games like PUBG had FPS drops and bit of a performance decrease.
WARNING:This also modifies your thermal-engine.conf file.
*Undervolting is an experimental feature.In case you do want to modify voltage values,open Smartpack/Kernel Aduitor Kernel Manager,go to the CPU Voltage Tab,and modify only the values labelled as "perfcl_Vmin".Reducing the values by 5 is recommended.
If during undervolting,the device freezes,simply long-press the POWER button until the device reboots.
*This kernel is not for heavy gaming.Please be aware while playing games/using heavy apps.
*RAM usage,battery life,performance etc. can vary with usage.Please dont complain about any problem if you apps
are wildly running in the background or you dont maintain your device properly.Sometimes it is not the fault of the kernel.
.Please provide proper bugreports(/proc/last_kmsg,dmesg output,/sys/fs/pstore/console-ramoops files can be provided)
otherwise your bugfix request will be ignored.
*Profiles are provided above.If you do have the time,do tell me how these profiles work out for you.
*This kernel gives me a maximum of a one-and-a-half days on a single charge.I use lots of apps and multitasking is smooth.Obviously,don't take these claims for real,test test test and apply settings that are perfect for you.
Everything depends on how you use it.

you have to try. it should because of anykernel installer but it isn't tested right now

Nice to see new kernel, thanks for contributing. What tweaks would you suggest for a balanced profile between performance and [emoji367]?

I was curious about this too. I typically don't care for only battery life, nor only performance, but a good balance.

Sorry guys, i use it out of the box. it's enough for me actually.
maple is a good io scheduler and touchboost brings a bit better reactiontime.
it's all that i can say for now.

First version was and giving me problems. It would lock up and I would have to force restart my phone. Overall this is a great kernel.

Same here (using long life zip) hopefully new update fixes these random lockups/freezes. Battery life is okay too but I think that's the Android 11 beta os's fault lol
