my card is reported by lspci as:

01:00.0 VGA compatible controller: NVIDIA Corporation GF114 [GeForce GTX 560
Ti] (rev a1) (prog-if 00 [VGA controller])

eglkms demo from mesa-demo works fine under 9.0.2, 9.1 and git

I update to libdrm but the bug was in my code I was open the device with python
open instead of the low level os.open which allows for O_RDWR.
