It still looks scary, can I implore to add some defensive layers with NULL-inits and handling of NULLs in the functions? It might not crash today... -- Petri Latvala
From: Rob Clark <robdclark@chromium.org> Add an initial set of tests for the gpu SUBMIT ioctl. There is plenty more we can add, but need to start somewhere. v2: add msm_device::gen and drop igt_msm_pipe_gen().. any test that needs to build even trivial cmdstream will need this so make it part of the util helper code Rob Clark (3): drmtest: Add DRIVER_MSM support msm: Add helper library msm: Add submit ioctl tests lib/drmtest.c | 3 + lib/drmtest.h | 1 + lib/igt_msm.c | 171 +++++++++++++++++++++++++++++++++++++++++ lib/igt_msm.h | 119 +++++++++++++++++++++++++++++ lib/meson.build | 1 + tests/meson.build | 1 + tests/msm_submit.c | 186 +++++++++++++++++++++++++++++++++++++++++++++ 7 files changed, 482 insertions(+) create mode 100644 lib/igt_msm.c create mode 100644 lib/igt_msm.h create mode 100644 tests/msm_submit.c
