Where i could find that SGX_ClipBlit test (source or binary)?

For mainline You will probably need
https://github.com/PabloPL/linux/commit/de0f7e299d94f5dfdcf15375ec2d3ace54ac4a24
because powervr is using some strange pointers.
I'm building my kernel and will get strace output of pvrsrvinit on my
device (where it's working) in few minutes.
For me it fails when trying to use egl programs (egl configurations =
0). Of course on mainline (5.0-rc4).
