I know that the boot img contains the kernel.. but how can i now change somthing inside?
ROMS I open with winrar and then change everything I want.
Does it work a different way at Kernel?

I hear that some kernals are better than others and I assumed they change when you change your ROM but I'm not sure. I feel like I would have better battery life with a better kernel.

I wanted to change the boot logo for i9300. Im well aware that you have to incorporate it in the kernel. I installed Ubuntu, the necessary libraries and brought the cyanogenmod source code. Only part is I dont have the necessary experience to tweak it using the NDK tools

View 1 Replies View RelatedI just installed the new BB froyo v.01 and it runs great, no force close or any market / maps issues. I noticed that it is running at 800mhz and I usually run at 1ghz. I tride both bekit LV1ghz and P3Droid LV1ghz and after reboot, I get a red light on the top of the droid and it says that my battery is too low (and my battery is fully charged BTW). My droid reboots after about 20 seconds....rinse repeat...I tried to remove the battery and put it back in, doesn't help.
Has this happened to anyone else?
Does anybody know if the new desktop kernel patch written by Mike Galbraith can be applied or modified to be used in the android kernel?

View 1 Replies View Relatedwhere I have got right now on my phone, which is:
1. I updated to stock 2.1 using the sprint update tool.
2. I followed the video tutorial to root the phone
3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?
I currently have bekit 1ghz kernet installed, but I was interested in trying out some other kernels. Can I just install them via Rom Manager over the first kernel? Or is there some kind of uninstall process I should use first?

View 1 Replies View RelatedWe know that the ROM is installed to the /system partition. Likewise the kernel ie boot.img is installed to the /boot partition of the device. I tried hard but could not find any reference to such a /boot partition(directory) in the root of the device. I would like know whether it is hidden or disguised as something else. The script that flashes the custom kernels has the following line
Code:
package_extract_file("boot.img", "/dev/block/mmcblk0p9");
(What is the block code for system and other partitions?)
Is mmcblk0p9 the /boot partition? Moreover /dev/block has no reference to boot or mmcblk0p9. So where exactly is the kernel being extracted? The boot.img comes packaged as zImage + ramdisk, In other words where are zImage and ramdisk extracted to, in the root file system and in what form? Is the ramdisk responsible for the creation of the root files system(/dev, /proc, /data. /system, /sys, /sbin etc)?
Well I am working on beagleboard-xm project, where I am supposed to upgrade the current Android version to ICS. The thing is, I have to keep the current kernel , because it is customized for some applications that run on that board. It is not me that compiled that kernel...
Is it even possible to keep the "old" kernel and upgrade to ICS? Can it be done in any way? Or a new kernel with new patches has to be installed...?

Galaxy Nexus using Android
What sections of kernel code are changed for optimization of performance.
Like we can change
1) the minimum free memory that android need to keep free.
2) Rate of clearing cache
3)Advanced LMK- where we can kill more than one process at at time when memory scarcity occurs.
4) Reducing logging.
5) In framework we can change the oom_adj value of important processes.
6) Implement Zram for kernel.
7) change the minimum and maximum no of process for AMS.
I want to know all the changes that can be made into kernel or framework code to optimize performance. I also want to know how can we implement swapcache for android kernel. What changes do i need to make in the code.
