[PATCH v12 00/23] TDX KVM selftests

Sagi Shahar
2025-10-28T21:20:55Z

This is v12 of the TDX selftests.

This series is based on v6.18-rc3

Changes from v11 [1]:
- Rebased on top of v6.18-rc3.
- Hook vm_tdx_finalize() into kvm_arch_vm_finalize_vcpus instead of
calling it as part of vm_tdx_create_with_one_vcpu. See "KVM: selftests:
Finalize TD memory as part of kvm_arch_vm_finalize_vcpus" which was
added to this series.
- Replaced vm_tdx_create_with_one_vcpu with vm_create_shape_with_one_vcpu
following Sean's patch to simplify creating VM shapes.
