Metadata about each device is stored on the filesystem in the directory: ${TMPDIR:-/tmp}/vfio-selftests-devices Within this directory is a directory for each BDF, and then files in those directories that cleanup.sh uses to cleanup the device. - run.sh runs a selftest by passing it the BDFs of all set up devices. - cleanup.sh takes zero or more BDFs as arguments and cleans up each device. If no BDFs are provided, it cleans up all devices. This split enables multi-device testing by allowing multiple BDFs to be set up and passed into tests: For example: $ tools/testing/selftests/vfio/scripts/setup.sh <BDF1> <BDF2> $ tools/testing/selftests/vfio/scripts/setup.sh <BDF3> $ tools/testing/selftests/vfio/scripts/run.sh echo <BDF1> <BDF2> <BDF3> $ tools/testing/selftests/vfio/scripts/cleanup.sh In the future, VFIO selftests can automatically detect set up devices by inspecting ${TMPDIR:-/tmp}/vfio-selftests-devices. This will avoid the need for the run.sh script.
