Hi Keil

for sources one can refer to Chapter 5 Graphics Linux Manual

and sect.5.1.5 Source Code Structure included in Linux 4.19.35_1.1.0 Documentation

As described in sect.5.1.1 Introduction :

"The GPU driver kernel module source is in the kernel source tree, but the libraries are
delivered as binary only."

Please also check i.MX_Graphics_User's_Guide.pdf,

Best regards
igor
