Hi Paolo/Sean,
This series contains patches to initialize TDX when loading KVM module.
The main purpose of sending this out is to have a review and for the
integration to kvm-coco-queue, but this series can also be applied to
kvm/queue cleanly.
v1 -> v2:
- Add KVM_INTEL_TDX to guide KVM TDX code. (Sean)
- Distinguish "TDX cannot be supported" vs "TDX fail to enable due to
unexpected failure", and handle them differently. (Sean)
- Update changelog accordingly
- Remove useless comments around tdx_enable() and tdx_cpu_enable()
(Sean).
- Add SPDX-License-Identifier tag to vmx/tdx.h
Btw:
I kept the name tdx_bringup(), tdx_cleanup() but didn't change them to
tdx_module_init() and tdx_module_exit() cause I feel KVM does more than
"module" init/exit. We can change that if needed.
v1: https://lore.kernel.org/kvm/cover.1730120881.git.kai.huan...
