hmm mayby this will help

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

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.
