This is necessary since\nthe test in 2/2 needs to run IPA in isolated mode.\n\nThe test tests two things:\n- Camera reconfigurations re-runs without stopping CameraManager\n- Fd leak across IPA IPA boundary.\n\nCurrently the test fails but a fix is already posted to the list:\n\"ipa: Use FileDescriptor instead of int in layers above IPC payload\"\n\nChanges in v2:\n- In 1/1, set LIBCAMERA_IPA_FORCE_ISOLATION to \"1\" instead of \"TRUE\"\n- In 2/2, include checkstyle fixes which were missing in v1,\n no code changes as such.\n- A tangential issue of \"runtime error\" had been seen in v1. It's\n in progress of resolving via \"IPC: Avoid memcpy() call with nullptr\"\n i.e. as separate series instead.\n\nUmang Jain (2):\n libtest: camera_test: Plumb constructor to set\n LIBCAMERA_IPA_FORCE_ISOLATION\n test: camera: Camera reconfiguration and fd-leak test\n\n test/camera/camera_reconfigure.cpp | 255 +++++++++++++++++++++++++++++\n test/camera/meson.build | 1 +\n test/libtest/camera_test.cpp | 5 +-\n test/libtest/camera_test.h | 2 +-\n 4 files changed, 261 insertions(+), 2 deletions(-)\n create mode 100644 test/camera/camera_reconfigure.cpp"}
