The headers and code that I copy between the two userspace locations
will go in libdrm when I have a kernel ABI, but vc4_drm.h can't go in
until merging to the kernel, and there's not a whole lot of point
without that.

Yes, I have thought about basing vc4-gpu-tools off of intel-gpu-tools.
I've actually tried to build and use the kms testing stuff on vc4, and
it was a total bust.  Someone needs to do a lot of work to make igt
useful for non-intel.  If you'd like me to build my vc4 testing inside
of igt, I'd someone to demo one of my tests building inside of igt, with
the test runner working and none of the intel-specific tests reporting
failure, and get me permission to just push code to that repository
(It's hard enough getting piglit tests reviewed, vc4-specific tests and
tools would never get review).
