A fully qualified python module, like 'selfdrive.controls.radard'.\r\n# 2. A path to an executable, like '/data/openpilot/visiond'.\r\n#       * If the module is not build, this application will try to build it\r\n#         from a Makefile in the parent folder.\r\n# 3. An empty string, which disables the module.\r\n#\r\n# Any value that does not satisfy any of the conditions above will trigger an Exception\r\n#   and abort execution.\r\n\r\nmanaged_processes = {\r\n  \"uploader\": os.getenv(\"OPENPILOT_UPLOADERD\", \"selfdrive.loggerd.uploader\"),\r\n  \"controlsd\": os.getenv(\"OPENPILOT_CONTROLSD\", \"selfdrive.controls.controlsd\"),\r\n  \"radard\": os.getenv(\"OPENPILOT_RADARD\", \"selfdrive.controls.radard\"),\r\n  \"calibrationd\": os.getenv(\"OPENPILOT_CALIBRATIOND\", \"selfdrive.calibrationd.calibrationd\"),\r\n  \"loggerd\": os.getenv(\"OPENPILOT_LOGGERD\", \"selfdrive.loggerd.loggerd\"),\r\n  \"logmessaged\": os.getenv(\"OPENPILOT_LOGMESSAGED\", \"selfdrive.logmessaged\"),\r\n  \"logcatd\": os.getenv(\"OPENPILOT_LOGCATD\", \"./logcatd\"),\r\n  \"boardd\": os.getenv(\"OPENPILOT_BOARDD\", \"./boardd\"),\r\n  \"ui\": os.getenv(\"OPENPILOT_UI\", \"./ui\"),\r\n  \"visiond\": os.getenv(\"OPENPILOT_VISIOND\", \"./visiond\"),\r\n  \"sensord\": os.getenv(\"OPENPILOT_SENSORD\", \"./sensord\"), }\r\n```"}}
