[kvm-unit-tests RFC PATCH 07/17] x86 TDX: Extend EFI run script to support TDX

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

 



Currently TDX framework is based on EFI support and running test case
in TDX environment requires special QEMU command line parameters.

Add an environment variable EFI_TDX. When set, enable test case to
run in TDX protected environment with special QEMU parameters.

Force "-cpu host" to be the last parameter as qemu doesn't support
to customize CPU feature for TD guest currently.
