After
  1. modprobe mali
Copy the Code
u need wrote
  1. dmesg
Copy the 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.

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.
  1. # modprobe mali
  2. modprobe: ERROR: could not insert 'mali': No such device
  3. # dmesg
  4. [17609.436928] Couldn't find the mali node
Copy the 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.
