Sam Lantinga c26946e9f2 Fixed bug 3792 - [KMS/DRM] Wrong GBM format 
Romain Tisserand

Using KMS/DRM driver from WIP SDL2.0.6 on Linux/ARM SoC RockChip RK3328 (ARM Mali 450 MP2 GPU).

The current code is using GBM_BO_FORMAT_XRGB8888 as GBM buffer format specifier.

The Mali driver (it has been confirmed some other vendor implementations too) expects GBM_FORMAT_XRGB8888.

The Mesa implementation is actually handling both values as the same, but it's not implemented like this into every gbm.h vendor header.

https://github.com/ideak/mesa/blob/master/src/gbm/backends/dri/gbm_dri.c

So with stock SDL2 on my card (Mali vendor implementation), it does not work, eglCreateWindowSurface fails, and gbm_is_format_supported fails too (with the BO variant).
It runs fine with GBM_FORMAT_XRGB8888.

Here is a link of the gbm.h from Mali user-space driver :

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting
with README.md

Enjoy!
