Mali userspace driver installation.
-----------------------------------

This repository contains a complete set of Mali userspace drivers, including
proprietary OpenGLESv2/EGL binaries.

Prerequisite:
-------------

You will need to have a matching version of libUMP installed.

You can get this from the linux sunxi package server, which is
documented at http://linux-sunxi.org/Packages

Or you can manually build libump from the sunxi libump git repository at
https://github.com/linux-sunxi/libump

Cloning this repository:
------------------------

> git clone https://github.com/linux-sunxi/sunxi-mali.git
> git submodule init
> git submodule update

This should make sure that you fully set up this repository and the
sunxi-mali-proprietary submodule.

Installing the binaries:
------------------------

First off, while there are some android binaries present, there is currently no
support for installing the android binaries, you will have to do so manually.

When everything goes well, all you need to do is run:

> make install

This should autodetect things, and install the correct mali GLES and EGL
libraries in your system.

Verifying the EGL/GLES installation:
------------------------------------

After installation, run the following to build the hello triangle utility:

> make test

When this succeeds, you can attempt to run it:

> test/test

If this shows a colourful triangle in a grey background measuring 480x480 then
all is fine!

This test application will also print EGL and GL information to the command
line.

Do make sure that you are either on the console for the framebuffer binaries to
work correctly. For X11 binaries, do make sure that X has started.

More control:
-------------

The build system tries to detect a few things on its own. It creates a
config.mk which can be remade by running

> make config

The build systen will try to determine which version of the userspace
binaries need to be installed. It will use the utility in version/ to query the
kernel driver for its version. So please make sure to run this on the target
system with the mali kernel driver loaded. The mali driver version can be
overridden when configuring with the VERSION= argument. Possible values are
currently 'r2p4', 'r3p0', 'r3p1', and 'r3p2-01rel1' (which also supports rel2).

The build system will try to determine which of the 'armel' of 'armhf'
toolchains your system uses, so that the correct binaries can be installed. This
can be overridden at configure time with ABI= argument. Possible values are
'armel' and 'armhf'.

The build system will try to detect whether libX11 is installed, and if so will
default to installing the x11 binaries. This can be overridden with the
EGL_TYPE= configure argument. Possible values are 'framebuffer' or 'x11'.

Running:

> make config VERSION=r3p1 ABI=armel EGL_TYPE=framebuffer

will remake config.mk with the respective values.

Subsequently running:

> make install

will then install the lot into your system.

To remove all built files, and even the configuration, run:

> make clean
Something went wrong with that request. Please try again.
