Mali GPU driver

Guys guys I have my own Arch linux version made for an OrangePi PC, ¿Could someone please help me with the OpenGL drivers? I tried almost everything and couldn't make it yet =/

Hi Guys

I build mainline kernel and U-Boot and make Arch linux image.
Arch Linux image with Mainline kernel and U-Boot

I tried install mali driver into this image, but run modprobe return error.

My board is Orange Pi 2.
I used magicse uploaded driver.

Could anyone help me?

After

modprobe mali

Copy code

u need wrote

dmesg

Copy code

for watch why driver not loaded...

It's also necessary to compile the mali driver for your kernel.

There is no MALI in mainline.

hmm mayby this will help

https://github.com/Icenowy/sunxi-mali

it is not official supported so not much information about it

but these source build with the newer kernels

Thank you for reply.

I can now build latest official mali driver r8p0.
https://developer.arm.com/produc ... ivers/utgard-kernel

I applied some patches and use "sunxi.c" from github you presented.
I maked Arch Linux Package is here.
                     https://mega.nz/#!UW43iJJA!aleUd ... QniF30n-s86HJZFSvTI


But it still does not work.

# modprobe mali
modprobe: ERROR: could not insert 'mali': No such device
# dmesg
[17609.436928] Couldn't find the mali node

Copy code

This message is sended from "sunxi.c".
I think need build device tree driver like "allwinner,sun8i-h3-mali", but I have never made a device tree driver.
Does anyone have an idea?

I build git rep, but same result.
There is mali DeviceTree in A23 and A33.
https://git.kernel.org/pub/scm/l ... 7461f3f424d03942d88
But H3 is not provided.
I will wait H3 mali DeviceTree.

Thanks very much!!
I applied armbian patches and succeed to load mail kernel module.
