wayland utgart mali drivers multiple contexts

Hi

I used wayland drivers for mali 450 from 

https://developer.arm.com/products/software/mali-drivers/user-space

mali-450_r7p0-01rel0_linux_1arm64.tar.gz

and I also tried some rockchip builds

https://github.com/rockchip-linux/libmali

but only HiKey drivers are working fine with weston 

so I am really able to start another wayland app in  weston run. (some initialization problem)

Are there any change that other drivers wasn't properly compiled?

They all works with qt5 with eglfs so when just one application run.

Can you explain where is the problem?
