GPU driver in Tizen OS

Hi, all
   I am porting Tizen2.4 to Orangepi+, and the X window system failed.
I use mali_drv.so(I got from some place without sourcecode:L), and when X starts, server load video driver,
but mali_drv.so call drm operation in the kernel.

error log:
[   280.214] (**) MALI(0): Use umplock across processes.
[   280.224] (EE) MALI(0): Error: mali_drm_open_master Unable to open DRM: No such file or directory
.
[   280.224] (EE) MALI(0): Error: Failed to be master of DRM!.
[   280.224] (II) UnloadModule: "mali"

As you know, kernel 3.4.39 don't support drm much.So I guess there is no drm driver in the kernel.
Can anyone help me ?

I wrote a DRM driver for the H3 kernel 4.5 (see http://moinejf.free.fr/opi2).I know that some people are working on the MALI driver, but I don't know its actual state.
BTW, does Tizen need X11?

Yes, before Tizen2.4, use X11 xorg version.
