RGB-Pi Custom Kernel
====================
This fork contains specific changes for special features like:
* Interlaced video
* Native CSYNC
Compilation
===========
First install Git and the build dependencies:
```sudo apt install git bc bison flex libssl-dev make```
Apply the Default Configuration Pi4 32-bit:
```KERNEL=kernel7l```
```make bcm2711_defconfig```
Apply the Default Configuration Pi4 64-bit:
```KERNEL=kernel8```
```make bcm2711_defconfig```
Customising the Kernel Version Using LOCALVERSION (Optional):
```CONFIG_LOCALVERSION="-v7l-RGB_PI"```
Building the Kernel locally Pi4 32-bits:
```
make -j4 zImage modules dtbs
sudo make modules_install
sudo cp arch/arm/boot/dts/*.dtb /boot/
sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/
sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
sudo cp arch/arm/boot/zImage /boot/$KERNEL.img
```
Building the Kernel locally Pi4 64-bits:
```
make -j4 Image modules dtbs
sudo make modules_install
sudo cp arch/arm64/boot/dts/broadcom/*.dtb /boot/
sudo cp arch/arm64/boot/dts/overlays/*.dtb* /boot/overlays/
sudo cp arch/arm64/boot/dts/overlays/README /boot/overlays/
sudo cp arch/arm64/boot/Image /boot/$KERNEL.img
```
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
