Daniel Verkamp 9fde8f499a examples/baremetal: exit instead of hanging Use an INT3 (0xCC) instruction to cause the example to exit after printing the message. This is more convenient than having to manually kill crosvm from another terminal. BUG=None TEST=Run baremetal and observe that it exits Change-Id: I4baeecca41d156c82bb1e1b27d0f8c2ba93959f9 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/3691966 Reviewed-by: Anton Romanov <romanton@google.com> Reviewed-by: Alexandre Courbot <acourbot@chromium.org> Commit-Queue: Daniel Verkamp <dverkamp@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com>		2022-06-23 22:30:40 +00:00

README.md

This is a small baremetal x86_64 application that can be booted with crosvm. You can simply do cargo run and it'll build it and use crosvm from PATH to launch it. Alternatively you can build it with cargo build and run with crosvm run --disable-sandbox path/to/target/x86_64-naked/debug/baremetal

The application does nothing but output Hello World! log line over serial port and go into infinite loop. This is expected and you'll need to kill crosvm to stop it.
