Hi!
First, I'm sorry to my little English. please understand.
I'm a newbie kernel maker. I saw some kernel post. example, siyahkernel and how to kernel compile... etc.
then I known how to add governor, io scheduler and update wifi driver.
but I want how to update mali driver and another specially driver or source.
I downloaded mali android driver. hmm... but I don't know.:crying:
How to update mali driver or add kernel driver?
Please advise to me!
ps. please explain to add kernel driver is anything.
umm... that's hard question?
then, where do other kernel developers know update or add kernel driver?
...

hi.. i need some advice/guide regarding this matter..
first of all, i'm planning on compiling custom kernel myself for my ace. i've succesfully compiled a kernel on my debian box using kernel sourcecode from samsung and also applied bfs patch. but now i dont want to just stop here.
the problem is i dont know where to look for those undervolt patch, smartass governor patch, interactive governor patch etc etc. gooling for "android kenel patch/module" just bring me to precompiled kernel thread, not the source patch itself. so maybe anyone can guide me the right direction? thx before

better to see the github site, lot of kernel source with many patching in there. and i think, for the much customized of samsung kernel, you can just patching, manual diffing will more better because samsung kernel is not vanillaish android kernel. much modification in there.

Custom kernel for the Ace on it's way..?
Hello,
In these last weeks i have been cooking and modifying my kernel's device.
Successfully. Changed all sorts of things, memory management, kernel, filesystem made it linaro compilable and so on so on.
However i have been unable to update the Mali Driver. It is currently running r2p4, so is UMP.
Any tips, or anyone could share his own experience on the general steps that one has to make in order to update the graphic driver ?
Thank you in advance
Hi everyone!
I have a nexus 5 with Android 4.4.4 (hammerhead). I would like to make few changes to the io scheduler (fair scheduler for example) but I am not sure where to start. I hope someone can guide me
The thing that I want to modify in the io scheduler is to add two steps:
1) before selecting the next task to run, check its pid to recognize if it is a task of a specific process
2) schedule it on a specific core, or migrate it to a specific core
Forgive me if I am lacking of more details but I am relatively new to kernel stuff
Does anyone have any suggestion on how to add those 2 steps?
Thanks
Maybe the question is too narrow...Even a guide to understand the source code of the CFS scheduler implemented in Android would be more than fine at this point...I could not find a good one. Any suggestion for where I can find an explanation of the CFS source code?
Solved

Never mind...thanks anyway!
I have solved by setting the affinity of a given process to a specific core.
I have never rooted it or touched my g850 's kernel, it is 5.0.2 lollipop and kernel version is 3.10.9-8213318.
I want to benchmark performance and power consumption on exynos5430 with HMP scheduler and Energy Aware Scheduler.
I have 2 questions about that.
Is my g850's kernel include HMP scheduler(Global task scheduler)? I mean, does it applied on my kernel and my g850's processor is running with HMP Scheduler without any configuration?
And, If I want to install 3.18 kernel which include Energy Aware Scheduler, what kind of defconfig i have to use?
I checked arch/arm/config, but there are only arm's fundamental defconfig files.(like acs5k, armadillo, exynos, versatile .... etc)
Is there any defconfig for g850? or can I use 5430-base_defconfig(I can't paste link here)?
I've been built kernel for linux, but I'm new to android, so I wish you guys help me for this...

If I compiled 3.18 kernel, How can I install it on my device? I tried to unpack original rom and change kernel image, but it's md5 file, so I dunno how to. Is there any ONE SIMPLE WAY to just install my zimage on my device? or appropriate guide to install it on g850. I found bunch of guides on google, but most of the uses nexus.
I'm so desperate to do this, I wish I can get an answer here. Thanks
