For those unfamiliar with intel-gpu-tools, it’s a collection of tools for GNU/Linux distribution that allows the debugging the official Intel graphics driver for Intel GPUs. Tools include a GPU hang dumping program, performance microbenchmarks for regression testing the DRM, as well as a performance monitor. The latest release, intel-gpu-tools 1.21, adds quite a bunch of changes, including automatic loading of DRM modules when opening a DRM device, much-improved GPU quiescing code to more thoroughly flush pending work and old data, as well as production support for the Meson build system while automake is still kept around.
