    "content": "This series adds a new test to lc-compliance that tests queuing a lot of\nrequests at once and hopefully exposing the issue described in [1].\n\nI hardcoded the amount of buffers to allocate at once to 8 since more than that\nwould cause errors when allocating.\n\nHirokazu,\nsince you have a patch series addressing this issue on the IPU3\npipeline [2], could you test this series? If both my and your patch series are\nworking, lc-compliance should crash before applying your series but run through\ncompletion after applying it.\n\nChanges in v2:\n- Renamed and reworded commits and series\n- Dropped patches 2 and 3, which were hacks to test, and added patch 1 to add\n  count to FrameBufferAllocator\n- Thanks to Niklas:\n  - Created new standalone test instead of looping over the other tests\n\n[1] https://bugs.libcamera.org/show_bug.cgi?id=24\n[2] https://lists.libcamera.org/pipermail/libcamera-devel/2021-April/019108.html\n\nv1: https://lists.libcamera.org/pipermail/libcamera-devel/2021-April/019139.html\n\nNícolas F.
