Change in drmtest base opening function allows it to use __drm_open_driver_another(N, ...) out of order, for example on board with three discrete GPUs: __drm_open_driver_another(2, DRIVER_INTEL); __drm_open_driver_another(0, DRIVER_INTEL); Second solution for Xe is based on filtered views. Both allows to quickly write tests. There is still drawback of not printing in children logs for first opened device. I renamed lib from lib/i915/igt_multigpu.* to lib/intel_multigu.* as I do not know of any non Intel developer using igt for such tests. v2: corrected two patches which introduced multigpu lib (Dominik) rebased patch intoducing Xe multigpu macro, corrected description v3: corrected include in first multigpu patch (Dominik) fixed typo (Dominik), refactoring code with Xe and gem macro (Kamil) v4: corrected typo in macro (Dominik) v5: removed cached names and relaxing checks for filtered devices in 3/8 patch, added Janusz to cc in 1/8...5/8 (Kamil) v6: extended description of patches 1 and 2, fixed bug in 3/8 (Janusz) improved usage of _is_already_opened() (Kamil) Cc: Janusz Krzysztofik Dominik Karol Piątkowski (4): lib/igt_device_scan: Introduce filtering out non-PCI devices lib/drmtest: Introduced drm_open_driver_another lib/intel_multigpu: Introduce library for multi-GPU scenarios lib/intel_multigpu: Introduced gem_multigpu_count_class and igt_multi_fork_foreach_gpu Kamil Konieczny (4): lib/drmtest: allow opening cards out of order lib/intel_multigpu: Add xe_multi_fork_foreach_gpu tests/intel/xe_exec_basic: add multigpu subtests tests/intel/gem_mmap: add basic multi-GPU subtest lib/drmtest.c | 85 ++++++++++++++++++----- lib/drmtest.h | 1 + lib/igt_device_scan.c | 21 ++++++ lib/igt_device_scan.h | 2 + lib/intel_multigpu.c | 135 ++++++++++++++++++++++++++++++++++++ lib/intel_multigpu.h | 36 ++++++++++ lib/meson.build | 1 + tests/intel/gem_mmap.c | 77 ++++++++++++-------- tests/intel/xe_exec_basic.c | 36 ++++++++++ 9 files changed, 350 insertions(+), 44 deletions(-) create mode 100644 lib/intel_multigpu.c create mode 100644 lib/intel_multigpu.h -- 2.42.0
