Thanks! What would be the best way for kunit_tool to: 1. Know that the tests have completed as QEMU will be just sitting there with kernel complaining about the absence of init (or running whatever we give it as init)? 2. Read the test results from debugfs under QEMU virtual machine while the kernel is still there? I think supplying an init script/binary that copies the /sys/kernel/debug/kunit/results/* to a 9p shared dir set up by kunit_tool would work but it would add a step of cross-compiling and packaging a userspace binary.
