The program intel-gpu-tools from git is crashing on startup. When starting intel-gpu-tools using the -f option, the following messages are shown:
intel-gpu-overlay: gpu-perf.c:340: request_add: Assertion `class <= I915_ENGINE_CLASS_VIDEO_ENHANCE' failed.
intel-gpu-tools version 1.18 opens, but shows the GPU usage as "idle", while version 1.22 opens and shows, in the part where it should show GPU usage, "i915.ko tracepoints not available".

It intentionally doesn't adapt to different versions of the tracepoints, I suspect you need v4.19 currently (and v4.19 won't be for another 3 months...)
Does this still happen with a recent kernel?
Using latest kernels (5.0-rc) and latest intel-gpu-overlay it works correctly. It is only failing when older kernels, as 4.18.0-15, are used.
