[Mesa-dev] [PATCH 1/2] egl/dri2: implement platform_null (v2).

[Frank Henigman]

The name "surfaceless" suits me.

Does this platform need to provide a hint to the user about buffer format?
Platform drm does this via the EGL_NATIVE_VISUAL_ID query of
eglGetConfigAttrib(), returning a gbm format value.  Unless we do the
same or similar here, how does the user robustly find the right format
for allocating buffers?
