Hi,
Here is v4 of TDX VM/vCPU creation series. The main change is to rebase
on top of Sean's "KVM: x86: Free vCPUs before freeing VM state" which
will go into v6.14. Instead of introducing separate vm_destroy and
vm_free callbacks, vm_destroy is moved at end of kvm_arch_destroy_vm.
Detailed changelog from v3:
KVM: VMX: Refactor VMX module init/exit functions
- fix modpost issues [Kai]
KVM: VMX: Initialize TDX during KVM module load
- extract cpus_read_lock() out of __do_tdx_cleanup [Kai, Chao]
- removed kvm_can_support_tdx()
KVM: TDX: Get system-wide info about TDX module on initialization
- fix for introduction of __tdx_cleanup
KVM: TDX: create/destroy VM structure
- included two patches from Sean's "Free vCPUs before freeing VM state" series
- replace vm_free hook with vm_destroy, introduce new vm_pre_destroy [Sean, Yan]
- rename tdx_vm_free to tdx_vm_destroy
- remove TDX_SEAMCALL_RETRIES from __tdx_reclaim_page
KVM: TDX: initialize VM with TDX specific parameters
- squashed "KVM: TDX: Set arch.has_protected_state to true" [Kai]
