> libGL error: drmMap of framebuffer failed (Invalid argument)
> libGL error: reverting to (slow) indirect rendering
I've been wondering about this, I mentioned it to Alan + Keith at XDC,
I've had to patch my libdrm to be okay with an 0 length mmap,
Something like I'm sure TG have done something different or maybe just
never checed this in ..
Dave.
