[PATCH 3/4] kunit: tool: Allow overriding the shutdown mode from qemu config

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Not all platforms support machine reboot.
If it a proper reboot is not supported the machine will hang.
Allow the QEMU configuration to override the necessary shutdown mode for
the specific system under test.
