[Kernel] Lightspeed 0.1.1 - Faster than fast enough.

FOR 1.5 ROMS ONLY.
Thanks to teknologist, maxisma, toastcfh, and all those who contributed to cracking the CPU open for overclocking.
Looking at the CDMA forums, it seems they were a step ahead of us with their kernel speedups. With help from their work, and particularly, from toastcfh, I've been able to patch and compile a kernel based on teknologist 1.9 with added features and speed.
Added features and changes so far:
- BFS, brainfuck scheduler. Basically, helps the CPU respond faster.
- Overclock. Up to 768MHz is enabled, but defaults to a safer 595MHz. It should be compatible with SetCPU. Be sure to use the custom setting.
- Deadline I/O scheduler. It should make file read and write operations a tad faster. We'll see if it really does.
Git repo: http://github.com/Soaa-/-lightspeed/tree/master/kernel-hero/
It runs at 595MHz! How do I make it faster?
Download and install SetCPU. It's available for free on xda-developers, but you can support the author by buying a copy on the market. Launch SetCPU and pick the custom option.
My phone doesn't wake sometimes! Or, it wakes and the crashes!
Use SetCPU and set the CPU governor to 'performance'. Try lowering the clock speed if the problem persists.
Can I flash this on recovery?
The first overclocked kernel was available only as sources, and binaries had to be flashed manually. Lightspeed comes as a standard update.zip package to be flashed through recovery though.
Does Wi-fi work?
Yes.
Does compcache/ramzswap work?
No idea. I don't use it.
Is it noticeably faster?
Yes. This isn't a 5% increase in speed, where the difference is only seen through benchmarks. Most phones can handle 691MHz, which is a 30% increase in speed. The lucky ones who can clock up to 768MHz get a 45% increase. The net result is a more responsive phone.
Does the CPU frequency scale to usage?
It can, if you keep the ondemand CPU governor. However, there have been reports of instability using the ondemand governor, so the performance governor is recommended instead.
Do you accept donations?
Not yet, as my work so far has just been putting other people's work together. My priority now is to make our phones better, not to make money.
0.1.1
Integrated setcpu.txt into update.zip.
0.1
Initial release

Hi,
Looks great! Does it work in 2.1 roms?
Greetz

I want to know also
Does it work on 2.1 oms ??

Sorry, the kernel is made for 1.5 ROMs only. The only decent kernel for 2.1 is still the same leaked one from a while back, I think.

ok, gonna try it now on a 1.5 rom, with setcpu.
let you know if speed is there

i use a stock rom, and have the recovery menu so can i put the zip on the sd card and then flash it ?

I am also interested in a guide on how to install/flash this properly.

Just like knudsen81 said. Everything working perfect with CPU running on 595Mhz.

From what I see, it should be flashed like all other kernels so just like ROM or radio.
Does this kernel scales overclocking depending on CPU load? For ex. lowers when idle or screen turned off.

when setcpu launches, it doesnt have the "auto detect" option
when i click on custom, it shows 528 max and no more..
what am i doing wrong here?
flashed the update.zip like a normal rom/radio btw.

Good job! looking forward for testing. What's actually missing from making overclocking work with 2.1?

I used Overclock widget to see the speed of the CPU. I only wanted to confirm if the 595Mhz was true
Also Linpack score went from 2.3 to 2.6.

Create a file named setcpu.txt at the SD card (so it will be /sdcard/setcpu.txt)
and enter the following into that file:
Code:
96000,115200,134400,153600,172800,192000,211200,230400,249600,268800,288000,307200,326400,345600,364800,384000,403200,422400,441600,460800,480000,499200,518400,537600,556800,576000,595200,614400,633600,652800,672000,691200,710400,729600,748800,768000
This will allow setting frequencies from 96 to 768 MHz via SetCPU

Thanx 4 the great work.
2 questions.
first, what does "Git repository" means and when will u release it?
second, can i flash it over Modaco 3.2 through recovery mode?
sorry 4 my bad english.

thanks for the help, lets try this out and see what happens =P

worked like a charm, thanks a lot =)

Does the camera work?

Camera, WiFi should work because it's an (old) 1.5 Kernel.

Other overclocked kernel works faster than this one (and with this one i've freezed ..) ..
With the other linpack gives me 3.2 3.3
with this 2.6 at max ..
:/

Have you set the cpu to 768? because the other kernal runs at 710 by default where as this runs at 595 but can be clocked all the way up to 768.
Please read the forums before complaining it doesn't do something.

Oneplus 3 - PubG Lags!

I've a OnePlus 3 Device.. When I Play Pubg in Med Settings.. it Lags like hell and i turned to Low Preset Still The same any solutions???

There was same problem with me too...
1. Make sure upgrade to v0.4.0.
2. If problem still continues use Elementalx kernel and overclock cpus and also turn on GPU boost to high.
Though regardless to say play on Europe server?
I play with framerate set to HIGH and BALANCED and it runs smooth most of the time.....

Will Try :good:

i'm on latest OOS beta with Derp kernel, no lag what so ever on PUBG , just played it for the 1st time last night, on HD and medium fps (and one mission on high), no lags what so evert, but here's heating normal and expected with this type of games, but didn't effect the game play.
it'll hit the battery though , i went from 92% to 20% in 70 mins of continues playing on high settings. also make sure if you're on OOS to add it to game do not disturb mode, it helps.

i do have same problem on open beta, ill try to flash costum kernel...hope they fix this on next update...

Sorry to say but it will lag in anyway
Coz it is powered by Snapdragon 820 which just sucks in gaming , not becoz of GPU (Andreno 530 is good enough) but becoz of low cores count and thermel throttle ?
And PUBG mostly depends on multicore performance of the processor, in which sd820 littrely sucks (820=450 in multicore performance)
Snapdragon 660 is much better choice for gaming it's much stable than 820/821

Someone said to me to use GFX Tool on play store and enable the vulkan and see the changes. He said it was lagging but after enable the vulkan it turns out pretty smooth after but pretty much drains the battery.

I second this, used GFX Tool with the following parameters:
PUBG M Version 0.6
Resolution: 1280x720
Style: Classic
Graphics : Balanced
FPS: 60fps
Vulkan : Enabled
Anti-Aliasing: Disabled
Running On DU v12.3
Kernel DU stock
Active battery drain after 33mins of use 9% and lags at all.

I dont know, it was smooth here currently on Nougat Zenity RR. But I do also face the lag when I'm using Unofficial RR Luis and I even overclocked the cpu, but it was smooth on OOS with stock kernel and MSM Xtended so far before. That recommendation to enable vulkan was from someone I haven't test it yet since I dont face the lag right now. Sorry can't help much, I also did not understand much why.

Not true , as mentioned on another post above, I also use the latest oos beta ROM, with derp kernel 4.4 , nonlags what so ever , not even a little ...
I've been playing pubg for a month now , and with the above setup I had no lags... I even use maple I/O sched , which by nature may cause some lag and despite that it doesn't.
onePlus stock kernel specially on beta may have issues from time to time, and a lot of cutom kernels for cutom ROMs are configured more toward battery life...
For stock rom use either derp or blu_spark, they will work out of the box without issues, Blu have more heating though on my experience.
For custom ROMs you'll need to ask the kernel dev what settings anss scheds to use ...I'd imagine flash kernel will be ok right out of the box but will not be as battery friendly as the others .

No
Well if you are happy with 20-35fps performance, than trust me you don't really need a flagship, you will be satisfied even with Snapdragon 450 which can give similar performance to sd820 in PUBG lol [QUOTEuke7;76899133]Not true , as mentioned on another post above, I also use the latest oos beta ROM, with derp kernel 4.4 , nonlags what so ever , not even a little ...

Guys if you want to game dont do it on a mobile device. Let alone a cheap China device with high failure rates on hardware.

Could anyone suggest a ROM / Kernel that is tried and tested to not lag on OnePlus 3T? I am currently using a different phone just to play the game and I really wish to move back to my phone ... Any method that is tried and tested to function properly with no lags on the current PubG update would be really appreciated

You will be hard pressed to find a combo that works. You will most likely need to build a rom made for it as most roms are not made for gaming which to be honest is a sad state on mobile device.

Try msm extended pie and aosp extended pie both with stock kernel runs pubg smooth with hd - high fps

Well i'm baffled with you guys, i ran it just fine, i even downclocked it to 1 & 1,5 Ghz (lil&big). My configs: Omnirom and the included kernel (holydragon) downclocked, display driver updated to V313 (look for adreno driver in mi mix forum) use rev15 as it is less glitchy and even has tangible score boost almost 6000 gain in antutu GPU section. And that's it, HD and High setting acquired, i even get extreme setting when i first install the driver, but somehow it disappears lol. If you want to run it even better, use old gfxtool to old pubg apk, run and then update the pubg, immediately uninstall the gfxtool to avoid ban by the new pubg detection for gfxtool. Sorry too long.

Benchmark problems

So just today, I realized I was under clocking my phone's CPU at 1920 mHz instead of the base clock speed of 2150 mHz which basically meant I was limiting its performance. Realizing this, I called myself an idiot and was also excited to see my benchmarks at base clock since its 165K using antutu when under clocked. So I changed my clock speed back to 2150 mHz and started benchmarking. All was going well until around 80% of the benchmark when the screen just instantly turned off and the notification light dimly lit up, no warnings, just instant. I can't interact with my phone until I forced restart it. I under clocked my phone again if it still has the same issue but benchmarking worked out just fine. Any idea why this happened and is there any fix? I really want to know my benchmarks at 2150 mHz ;-;
Ps: idk how to call website admins but please tell them to fix their website for PCs, can't even login since text boxes are missing, can't make a new thread since title input text box is missing when making new thread. Everything is fine on phone tho.

Im using nameless kernel. I now just remember having this same problem before and rebooting doesn't work, and i also remember that this problem is the reason why i underclocked my phone. The only thing that caused a kernel panic so far is antutu, probably geekbench too but i can't properly remember.

Kernel cpu frequency

Hi guys,
I have problem with my s7.
I rooted and installed black diamond rom. With moro kernel.
I oc cpu min freq to 2.4 max 2.6
But whenever im playing games like pubg, cpu goes down by itself, to around 1.2ghz or 1.4ghz.
I don't know if it's throttling or? Pls anything you can do to help me? Or does anyone else experience d same?

It won't stick, unless you disable any hotplug enabled.

Are you sure, coz i did that before, still did not stick, i don't know if it's a problem with s7 flat users.
Right now currently on stock.

When I disable hotplug, I can mess with the CPU the way I want, I'm on xFire with latest Moro kernel.
Maybe your kernel is in enforcing mode? IDK if that matters, but try disabling it too.

If so, I'll just assume it works, okay I'll try your rom.
But nees to ask, do you play pubg mobile on you s7?

It's been months since I've tried PUBG, never had to lock the cpu or gpu to get a stable performance as it was already smooth.

Question POCO F3 CPU min/max frequencies constantly changing by themselves

This is my first post on XDA. Recently, I got a POCO F3. Today, I tried various combinations of mods and custom firmwares and when I check in Franco Kernel Manager, my CPU min and max frequencies are chaging bby themselves. This is just with root and custom recovery installed. I thought a custom kernel may fix this, but it didn't (I tried Immensity-X, WildAngel Performance and NoGravity). As well as that, I'm finding that the GPU cannot handle an overclock or else the min and max frequencies will also fluctuate by themselves. The overclock I tried was to 682 MHz (my F3 isn't a silicon lottery winner). Does anyone have any idea as to what the issue might be?

you try flash last build NoGravity Kernel v1.0.1 + NGK App 6.1.1 (Hotfix) ?

Xiaomi does some crazy ass throttlings that limits cpu freq to 2.7k default and keeps changing with temperature 37*c, 39*c, 41*c and so on
same with gpu, gpu is not limited but it starts throttling at higher temperatures too but the problem with gpu throttling is that it doesnt revert back to highest when the temperature cools down, you'll have to revert it manually.
only way to fix this is if you edit the thermals yourself or use dynamic profile or flash thermal no junk

You can fix the freq. of both CPU and GPU to be max, and disable the mi_thermald. Try "extras/jitter-reducer.sh" in USB_SampleRate_Changer which has been developed for hi-fi audio use. But this can disable almost possible battery saving features, e.g., GPU power level, thermal throttling, doze, wireless connectivity optimization, etc., to avoid jitter distortion on all digital audio outputs.
Note: this is tested only on the STOCK kernel.
