What is a kernel?

this might be a stupid question, but what is a kernel and how do u use them? i know what a rom is and how to install but not a kernel....

Wikipedia definition:
"In computing, the kernel is the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components).[1] Usually as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources (especially processors and I/O devices) that application software must control to perform its function. It typically makes these facilities available to applicationprocesses through inter-process communication mechanisms and system calls."
Since Android is based on Linux: (don't know if this relevant)
"The Linux kernel is an operating system kernel used by the Linux family of Unix-like operating systems.[6] It is one of the most prominent examples of free and open source software.[7]
The Linux kernel is released under the GNU General Public License version 2 (GPLv2),[4] (plus some firmware images with various licenses), and is developed by contributors worldwide. Day-to-day development takes place on the Linux kernel mailing list.
The Linux kernel was initially conceived and created by Finnish computer science student[8] Linus Torvalds in 1991. Linux rapidly accumulated developers and users who adopted code from other free software projects for use with the new operating system.[9] The Linux kernel has received contributions from thousands of programmers.[10] Many Linux distributions have been released based upon the Linux kernel."

I have a question too.
When I boot ubuntu 10.04, the kernel comes up as 2.6.32, I think this is the same number as a previous android kernel. So how close is the android kernel to the linux kernel, us it a fork? When the new linux kernel comes out, will the android kernel be updated to reflect that?

What the little brown things are in a popcorn bag before you pop it XD

I thought it would be better to ask here than start a new thread but i have never installed a kernal before and was wondering how, do you just flash it in recovery? I have the desire rom and would like for my speaker to be a bit louder.

With kernels, I usually do ADB command.

It's the same with some Android and phone specific patches applied. A config file decides what architecture to build for and what drivers to include. That's what lets us bring in cutting edge features like compcache and BFS quickly.
Nice to think that your phone is running the exact same code that the world's fastest supercomputer is.

[SCRIPT][NDK] agcc wrapper mod for latest Android NDK

Here is an update to 'agcc' wrapper originally written by Andrew Ross. You can find his original version here.
Modded/Updated agcc
Helps you to quickly compile native C code for ARM, MIPS or x86 targets. I updated 'agcc' to try out a few existing exploits on Android, in hope of finding a few more to open up root for my new phone.
I thought some of you may find this updated script useful for compiling native code. I have tested these changes only on a Windows machine using Android NDK r8b.

[REQ]Anybody willing to compile MortScript as 64-bit version for me/all?

Source code here:
https://code.google.com/p/jscripts/source/browse/#svn/trunk/MortScript
MortScript currently only exists as a 32-bit version, it's development has been stopped years ago. Most today's computers are 64-bit, so it would be great to have a 64-bit version of MortScript, too.

[How to] Launch PC OS/software/services (Linux&Windows&OSX) on Zenfone 2 ze551ml
Hi ! I've found a way concerning apps for Linux & Windows compatibility, because we have x86 cpu, we are able to launch it (especially windows software with Wine and PlayOnLinux) after dedicated installation of Linux distribution chrooted (on img file or dedicated partition on SDcard), and search people can speak english and french to translate my tutorial (not finish yet) in english.
I'm searching a way to use VirtualBox too (trying to launch Windows & OSX), but we don't have linux-headers packages for our Linux Kernel, so i can't compile modules drivers for him, i've found a way with linux kernel of chrome-OS, maybe we can do something like that ?.
Concerning 2D and 3D acceleration, i've found a way with software mesa renderer, but a lib is developed here for translate OpenGL ES calls to OpenGL (like wine do the same between DirectX and OpenGL).

This is great news

I can work on translating your tuto in English.

Just using chrome

Raspberry Pi 4 can run both Android and Linux apps.

Hi,
We make a Debian based Linux distribution that runs as an application on top of Android.
For Raspberry Pi 4 we use KonstaKang's latest 64bit LineageOS 19 (Android 12).
Installation is as simple as installing Android APK's. You can download a free evaluation
version from volkspc.dot.org.
Regards
Vasant

This can also be done with apps like AnLinux, Andronix, Debian noroot, or with proot-distro in termux.

It has been a while since I updated thread - . We just made a new release yesterday. This is based on KonstaKang's LineageOS 20 (Android 13). We also provide a SDK so that developers can build their own Debian Bullseye based distribution.

Our Linux desktop is now based on Debian Bookworm XFCE 4.18. The SDK has also been updated to Bookworm. More details at volkspc.org.

Our latest release works well with both of KonstaKang's LineageOS 20 (Android 13) and AOSP 13.
