Hi @amine; the answer here: https://gitlab.freedesktop.org/lima/mesa/issues/73
-
You are right the blob: 'mali450r5p001rel0linux1fbdevarm64v8a' is the proprietary library executing the GLES operations on the mali 450. The linux GNU/GPL license is not compatible at all.
Indeed, we don't have a tutorial; On the framebuffer environement you just have to add the GLES headers on your gcc include directory, and add the 'blob' as a library.

Here is the glmark2-es2-fb output (hang at the refract test):

This setup is now working using the mainline kernel (megous 4.14 and the following patch: https://github.com/noblock/sunxi-mali/blob/master/kernel-patches/9902-megous-add-h5-mali.patch). Using the same r5p0 blob:
Once you have the kernel, here is the mali kernel module (r5p0):
https://github.com/noblock/sunxi-mali
Here is the general information:

Here are the steps to get a legacy H5 kernel running with Mali r5p0:
* Linux kernel from: https://github.com/OrangePiLibra/OrangePi_H5SDK
* Here is my legacy kernel generation script: https://pastebin.com/w1b4exzW
* Mali kernel module: DX910-SW-99002-r5p0-01rel0 from here: https://developer.arm.com/products/software/mali-drivers/utgard-kernel
* Mali kernel patch: https://pastebin.com/VnJgZWZJ (name: DX910-SW-99002-r5p0-01rel0.patch)
* Blob: mali450r5p001rel0linux1fbdevarm64v8a
* Good benchmark/test utility: glmark2-es2-fb. The blob is a aarch64 one, so we must use a aarch64 linux environment to compile and run glmark2-es2-fb.

I just checked the mali blob: mali450r5p001rel0linux1fbdevarm64v8a (fbdev) and this blob is working on the legacy kernel with the proper patches.
Nevertheless we may have some stability issues at the current voltage/frequence; Indeed gl-mark2-es-fb crashes around the refract test on my board.

The UART can be activated. GND, RX and TX are in a non-connected state by default. GND can be easily connected to the ground available on the printed circuit board. Enabling RX and TX require shunting two pins for RX, and two pins for TX, using the diagram below
GND RX TX 3.3V (serial connector) [] [] [RX] [TX] [] [] (empty component close to the serial connector) (shunt) (shunt) [] [] [RX'] [TX'] [] []
