Trying to get ODROID-XU4 Mali driver working on armhf

Hi,

I'd like to get the ODROID-XU4 Mali driver working, using native compilations.

The ODROID-XU4 uses an Exynos 5422 CPU which embeds a Mali-T628 MP6 Midgard 2nd gen GPU:
https://en.wikipedia.org/wiki/ODROID

I'm using the official ODROID kernel:
https://github.com/hardkernel/linux/

So far, a /dev/mali0 is present with rw root rights only.

The mali_dp kernel module isn't activated by default, and I don't know if it's the right one for this GPU.
I activated it, it has to be loaded manually, but doesn't seem to be useful. Is it ?
Code:# modinfo mali_dp

vermagic: 4.14.180 SMP preempt mod_unload ARMv7 p2v8It seems that this stuff is required:
- UMP (Unified Memory Provider) User-Space Driver
- UMP Kernel driver
- Mali Midgard GPU Kernel Driver

The UMP User-Space Driver can be found here:
https://developer.arm.com/tools-and-...ump-user-space
I'm using this one:
Code:$ tree -d DX910-SW-99006-r10p0-00rel0

It seems that the generated .so have to be manually packaged because the "make install DESTDIR" way doesn't work.

The Mali Midgard GPU Kernel Driver can be found here:

I'm stuck here, any help/explanations are welcome.
