Hi,
Actually I'm working on a project.
I'm building a kernel for MT6589 and found some changes between mediatek and AOSP (I mean the changes introduced by mediatek themselves)
Here is my work :
https://docs.google.com/document/d/1J2LxPTLSqpq71ivrfyXdKxtPnugISvvNnO-WzyxQBW0 <- feel free to comment and add information about what I've done, just don't spam
So I want to have a discussion here with other developers working on MT6589 kernel only
Our topic is to understand what are the differences introduced by Mediatek
Good work in finding out the changes. I hope this will help us in understanding the mediatek kernel more deeply and compile it with new features.
Btw, which device are you working for?
Faea F2S
do you believe that 6589 and 6589T are the same? i mean... do you believe that 6589T is just an kernel OC version of 6589?

Actually, I'm watching kernel part and not mediatek stuff so it should be the same.
They are the same. Its just a somewhere hidden file that lets the cores work on 1.5ghz instead of 1.2ghz.
Firmware of the same devices but with mt6589 or mt6589t are also working on both. There's just some configuration that enables the higher clock frequency.

Anyway, the most interesting part is the tuxonice on mediatek kernel (used for hibernating)
I'm still wondering what it really does (fastboot ? hibernate instead of power off ? etc...)
Any chance of adding usb otg support to kernel ? I have ZOPO zp910.
@Dr-Shadow , As you are working on OmniROM, I think you have access to the full source. Can you help us in building Omni for our device as we already have the kernel source and just need to know the required changes.
I know you are busy with your projects but when you get time please help us.
Thanks.

Really sad to see this development slowed down. Mt6589 had real potential if optimized i think.

although it has been a while...if you want to force an 6589 to be clocked like 6589T, you need to set this config: CONFIG_MTK_FORCE_CPU_89T = y

Actually, this shouldn't overclock the CPU on MT6589. It was a fix for MT6589T platform detection
custom kernel
MT6589 Phone users do need a custom kernel..

I didn't try building with this yet, but the code seems to overlock the cpu.
If this config is set, the related function returns a value to another function, in which max freq is set.

I just saw your post. The main idea here is to boot up the phone as fast as possible. It does not save apps, but it keeps the kernel in the ram with minimal features as possible so it wont drain battery as much. And as every hibernation it saves its last state for the essential stuff that will later transfer into ram. The whole idea is to skip bl and kernel loading part, and put sruff into ram that have been saved on the ssd

I removed this feature on my kernel because this stuff was not used. This made things more easy for merging AOSP patches

It needs to be triggered by the os for it to run. Most manufacturers dont use it becouse it may not be stable for the way it operates
It really isn't used? My stock rom boots up within few seconds, where omnirom takes much longer.
Gesendet von meinem T0LTE mit Tapatalk 2
In most cases - no. Sinve the kernel is still in the ram you cant boot anything else even if you need too. This may not be good on devices without removable batteries. And the second reason i got from one source(but im not really sure about this one) is that you need to prepare your rom to run this feature, and its not alwats being as stable( either kernel crashing or not being able to boot the os)

sg mini:
384 MB RAM, Qualcomm MSM7227, Adreno 200
totoro:
290 MB RAM, 830 MHz ARMv6, BCM Videocore iv.
And google says KK can "comfortably" run on devices with 312mb ram
so.... its a lil hard to predict if it could run on totoro...
however, JB May run...
Open GL can be handled.
camera and touch will be a very big speed braker on this one though
ONLY after it successfully boots on totoro... which again, cant be predicted
but i will go with a yes. with an improved Ramdisk we may be able to boot it
I wish we could make it have the source codes... and complete CM9 /10/10.1/11
Thanks for your concerning

Tassive cpu is from qualcomm
With full source
So overclocking and optimisation are available
Totoro cpu broadcomm
Incomplete sources- no actual overclocking and no optimisation

Wrong... wrong.
Those stats are for tass, not tassve. Tassve has exactly the same hardware as a Galaxy Y, and runs with the same BCM21553 CPU and VideoCore IV as totoro.
Remember,
Tass= GT-S5570
TassVe= GT-S5570I
totoro, tassve, cooperve and the Galaxy Pocket use the BCM21553 chipset.
It is true, however, that tass has full sources, and that is why they do have a somewhat stable KK.
Broadcom, like what madboy said, only released their sources because it was Raspberry Pi's second anniversary, not because of the petition. If it were, they would have released the sources shortly after the petition reached 10,000 signatures, but instead there was a lapse and they did not release it. Only on Feb 28, Raspberry Pi's 2nd anniversary did they release the sources. Even the main XDA site (not the forum) states that it was the anniversary that prompted Broadcom to release their sources.
Get your facts right.

I thought Broadcomm doesn't have the libs for camera or audio they are with samsung. So we are never gonna get it.
Correct me if i am wrong.

Wooow! Making smiles around the world, two packages containing Adreno drivers for Moto E users!
"This is the generic GPU drivers for adreno GPU found in snapdragon chipsets by Qualcomm.
Although this will not magically make your GPU fast, updated drivers will fix bugs and show improvements all round." ( @abhifx quote)
For AOSP/CM Lollipop 5.1.1 based
Stable:
This file is working without issues (until now) and a slight performance gain for CM12.1 and AOSP 5.1.1
Download: https://www.androidfilehost.com/?fid=24052804347848002
Unstable:
It's the last version of Qualcomm binaries. Runs 3DMark and Basemark with more performance, but it isn't okay to normal use. Well, if you wanna to compete with benchmarks (like in Hwbot) these libs are for you.
Download: https://www.androidfilehost.com/?fid=24052804347847159
Known bugs:
Antutu doesnt run 3D tests (other applications runs correctly) - Nexus related bug
Camera doesn't work
Video playback issues
Tested with:
Resurrection Remix 5.5.8 (Android 5.1.1)
You tell me
For Motorola Stock 5.1:
For Stock 5.1, I found another package in a latin forum. It works flawlessly!
Download: https://www.androidfilehost.com/?fid=24052804347847133
Tested with:
Stock Moto 5.1 Rom
lost101's Brazil 5.1 Optimized 1.1
Known bugs:
none (until now)
Installation:
- Boot into TWRP/CWM/Philz
- Flash respective zip file
- Reboot system
- Enjoy

wondering does cm team include these in rom or do we have to flash it on every rom update we flash (ofcourse based on cm12.1) ?
and yes the device seems more snappy and responsive.

This package is the last released by Qualcomm for Lollipop. The october 2015 version is exclusive to Marshmallow.
I think CM does include only when QC release the source (and this binaries are for developers, so it can not has the source released). Look at the disclaimer
This release is intended only for developers, and does not meet our customer release quality. Please refer to the included readme file for installation.

I can confirm that this runs on my device without any problems so probably also on other devices with GPU Adreno 3xx. I did not made a formal benchmark -however feel a light increase / clearly no stuttering or lower performance.

I forgot the rom name but there's a kitkat rom with no screen flickering issue by niropa (on lollipo bootloader). u can contact with niropa to solve screen flickering issue.
Yes,was in a wrong place, i have contacted a moderator, now is in android development.
Ok , i think cm11 its the most stable tree from cm team , i like KK because its more ligth weigth , i dont know why the developers wonma make roms unstable and buggies hehe , can u add a custom features? Like another toolchain? (Linaro , Uber) or new features from kernel? Like more i/o (zen ) , gpu OC or cpu OC?...
Anyway , Thank U its run great

See PACMan builds with overkill kernel by niropa. Just search in that thread and you'll find many ROMs like CarbonKK or PA, which are made to work on LP bootloader
Will this work on msim variant also? I read you mentioned xt1032 but still if you know..
It might work, but has been tested only on xt1032 aka falcon.

All work fine, bluetooth and hotspot work. I have tested it, the only warnings are 3:
-Do not active kernel samepage merging, you will have problem in camera
-install gapps only after the first reboot of the rom
-If you use whatsapp install it before switching to ART (in developer setting, for better performance select ART)
There aren't particular bugs

Is DU based on Android N preview? Autorotation works with N preview, for which this kernel is developed.

RACER_N5X_20160321
Feedback required.
Some governors may need to be tweaked if you have any freezes or RRs.
I am looking at your kernel and will report back with any findings I might make.
I'm glad we are getting options regarding kernels. N5X owners live in a bit a sad world ? for owning a Nexus device, the international dev community is astonishingly absent. So new blood is always appreciated!
Technical question: do you use a native Ramdisk or do you rely on anykernel? Meaning can we just cross-flash or do we need to create a clean basis when flashing your kernel?

Working with Kernel Adiutor, I get system lockups and reboots when trying to change cpu governor tuneables. Kernel Adiutor is also a hit or miss operation in general, aespecially after reboots.
Sometimes it refuses to launch, when letting the system settle for a couple minutes, it comes up.
I have disabled all boost and touchboost settings, there is still boosting going on (big 864MHz, little 12xx MHz). To rule out governors, I changed governors but the behaviour stayed the same. Regarding Kernel Adiutors weird behaviour earlier, it could be though that the new values I set never get written to the system. Not sure.
I also have random reboots, never caught one in the act, I only notice it when unable to unlock by fingerprint and I must enter my unlock pattern.
Log is from playing with governor tuneables.

Hello guys,
This is a project I was working on for a kernel for our SGY.
I made it with a few things in mind:
>Improve it's performance
>Be universally compatible (after I nearly given up on trying to get a snappier CM11 and after the need for a snappier SGY, I decided to go back to GB. However, BML is terrible, and it is annoying to come back to. I decided to build a MTD kernel for Gingerbread then, and it works!)
>Experiment and upgrade as much as I can (thanks @robcore!!!!)
But since I lost my device, I cannot continue developing it. I am then releasing the source code (sorry, no flashable stuff, I deleted it long ago ) for any of you to continue(?) my work if your heart so desires.
If I ever get myself another SGY (or another BCM21553 device), I will gladly continue development (and support whoever does it too), but before I lose all my data and the kernel code alongside it, I am making it available.
This kernel features:
-OC up to 1040MHz (It's questionable even today if the bcm21553 OCs really work, but I tried hacking a way that works very similarly to MarocOS's one, maybe even better. Be warned though, the source around it is messy)
-GPU hacks for performance (Again, even I don't know if they do work, probably the values are just there to be seen, I'm not sure. I do know though that increasing the CPU speed will much likely increase the speed of V3D too)
-DVFS disabled (I found out DVFS is mostly the culpirit in the "832MHz crisis" where the kernel would forcefully scale itself to 832MHz, so I eliminated any reference to it in kernel code. Apparently DVFS on the processor is only available under the bcm21553 governor, but it is present on the other drivers as well. The idea for disabling DVFS came from my friend @robcore)
-A few additional governors and a buggy interactive governor (which is the default xd)
-MTD support for Gingerbread (Thanks Samsung Epic 4G! Although it only works on TouchWiz (I tried it with SL v2 and v2.1 and it works, but under NougatME(CM7) I got no success and loads of segfaults), it works ALMOST perfectly. See bugs for details )
-Some scraped source code from Samsung's FSR I found on the internet (barely compilable, though)
Bugs:
>Gingerbread version:
-IMEI won't appear in the Status screen, I also faced problems with non-working radio for calls. Data works just fine, but calling and receiving calls is unavailable. I believe it is EFS-related. My suggestion is backing up the EFS partition's file structure, then converting it to MTD, then restoring the backup.
-TWRP will crash and panic when exiting, a workaround is force rebooting
>ICS version:
-TWRP will crash and panic when exiting (I believe fixing it here will fix the bug above too)
>KitKat version:
-Flashing images fail randomly, you may also be unable to reboot normally if you do so. I tried addressing this but I couldn't get anywhere.

Thanks to:
@robcore - his development on the Snapdragon S4 breathes life on my dev soul!
@zman0900 - I saw his thread on an MTD TW kernel for the Samsung Epic 4G, which led me to believe MTD on GB is possible.
nice kernel
It sound nice. I'm a newbie developer, I'm building a kernel to fix audio bug on cm9, hope it work. And thank you for the source

Have you gathered enough info on it? I would like to fix it too, but I couldn't get any info on whether if the audio bug is a kernel-side issue or an OS -side issue.
Best of luck for you
Building and fixing

I don't sure so I decided to build a kernel from your source and another cm9 version from Mohamad.Afaneh's source and I'll merge the audio on both of them for the best think to fix the bug.Thank you .
Link for kernel?

Compile one for yourself,man. It only takes like 15-25 mins

He wrote a script already, just add your toolchain and run the script. There's a guide in the readme

Ok. The watson-kernel-bcm21553-src is used with other files?
Because i want to make cm9 mohhamad afaneh optimized version

To make it, you have to sync the cm9 source code then add the files from his github to your localmanifest. This thing is not in anyway related to that except the MTD. This one is a kernel-compile only source
Oh man, i give up. I can't build a kernel from source, but i can modify a kernel.
Can someone give me the zimage for ics Please....

zlimage? We don't have that here, we only have boot.img for kernel

Or you can give me the extracted boot.img files. (ICS/KK)
I will rebuild it using dsixda's android kitchen.

Sorry but I can't because I'm bored of making ROMs so I switched back to Windows. I'm planning on making a ROM, I'll compile the kernel for you once I get linux installed

Sorry but I can't since my sgy is dead for a long time ago. I'll try to make one if I can find one. I've heard that there are some places that sell sgy for about 5 bucks, i'll find one ì possible
Be fast bro!!
