1 This is a mirror of the kernel validation code into the userspace GL library. 2 It is only built when USE_VC4_SIMULATOR is defined, for compiling the driver 3 on an x86 system with the simpenrose simulator. It allows testing of changes 4 across the kernel and userspace with exposure to most of the software stack, 5 on a higher-performance and more-debuggable environment than the native 6 hardware. 7
