End of the project

This project (along with MyyQi) started a long time ago, in order to get the various subsystems of RK3288 boards working on Mainline kernels, with all the bells and whistles, with the hope of having a Vulkan dev-board someday.
So this project incorporated the Mali GPL kernel drivers, that had to be used with the Mali Blobby GL drivers, which were updated by ARM at the time, with the hope that ARM would release Vulkan drivers for RK3288 boards !

Fast-forwarding 3 years later, mainline kernels now provide drivers for the GPU, some staging drivers for the VPU (using V4L2 Request API, which is rather unsupported...) and have incorporated various fixes that make them almost useable without patches.
Mesa now incorporates the OpenGL user-space drivers. There's still some work to do on them but, still, they can run an entire batch of glmark2 without major issues (just some weird drop shadows on one test).

Meanwhile, neither ARM nor Rockchip have updated the Mali user-space drivers, making them unuseable with newer Mali kernel drivers.
I tried to maintain the most recent version that worked with the old blobby drivers, but it has reached a point where it's not possible easily.
So I'm dropping the whole Mali user-space drivers support.

That means that this repository purpose has reached its end.

You can now enjoy (almost) every feature of RK3288 boards (except maybe Vulkan, unless someone wants to play with MESA) using mainline kernels and standard MESA OpenGL drivers.
The VPU part still requires a player able to handle V4L2 Request API correctly. But that should come soon enough in every distribution.

So this repository only includes a few remaining patches for Tinkerboard systems (as I'm pretty sure nobody uses MiQi boards anymore), and that's it.

Using the main script

bash GetPatchAndCompileKernel.sh

This works whether you cloned this whole repository or just downloaded the script alone.

Don't hesitate to edit the script and replace the CROSS_COMPILE value in the script, in order to match your cross-compiling toolset prefix.
If you don't use cross-compile tools (meaning that you're compiling on your ARMv7 machine), set it like this CROSS_COMPILE=

If you'd like to reconfigure the kernel using menuconfig, nconfig, qtconfig, ... do it like this :

# Assuming that you want to use menuconfig
MAKE_CONFIG=menuconfig bash GetPatchAndCompileKernel.sh

Now, you need all the tools required to compile a kernel.
That includes, at least, gcc, make, automake, bison, flex, bc, pkg-config and some SSL library development headers (libssl-dev on Debian systems).

In order to use this script, you'll also need : wget, git and bash.

Using menuconfig also require ncurses libraries and development headers (ncurses-dev on Debian systems).

Prebuilt kernels

Armbian provide premade Debian packages of kernels for Rockchip systems including most of the patches included here.

About

This repository provides patches and mainline kernel cross-compiling scripts tailored towards Rockchip 3288 boards.

The main cross-compiling script will :

• Clone the latest release or release candidate branch of the mainline kernel;
• Apply various RK3288 specific patches for Tinkerboard boards;
• Copy and use this repository configuration file;
• Cross-compile the patched kernel;
• Create the folder /tmp/Rockmyy-Build and install the cross-compiled kernel in that folder.
