How does patch work UNIX?

patch is a command that takes the output from the diff and puts it into a file. Then, it can take the filed output and overwrite another file with with the changes. For example, a common use is to use the patch to transfer changes from the changed file to the original file, thus making them identical.

How to submit a driver for the Linux kernel?

If you are submitting a driver, also read Submitting Drivers For The Linux Kernel; for device tree binding patches, read Submitting patches: the essential guide to getting your code into the kernel. This documentation assumes that you’re using git to prepare your patches.

How do you submit patches to the Linux kernel?

Linus and other kernel developers need to be able to read and comment on the changes you are submitting. It is important for a kernel developer to be able to “quote” your changes, using standard e-mail tools, so that they may comment on specific portions of your code. For this reason, all patches should be submitted by e-mail “inline”.

What are the steps for contributing to the Linux kernel?

Step 1: Prepare your system. Steps in this article assume you have the following tools on your system: Step 3: Build/install your kernel. Step 4: Make a branch and switch to it. Step 5: Update your kernel to point to the latest code base. Step 6: Make a change to the code base.
