* What's TDX?
TDX stands for Trust Domain Extensions which isolates VMs from the
virtual-machine manager (VMM)/hypervisor and any other software on the
platform. [1] For details, the specifications, [2], [3], [4], [5], [6], [7], are
available.


* The goal of this RFC patch
The purpose of this post is to get feedback early on high level design issue of
KVM enhancement for TDX. The detailed coding (variable naming etc) is not cared
of. This patch series is incomplete (not working). So it's RFC.  Although
multiple software components, not only KVM but also QEMU, guest Linux and
virtual bios, need to be updated, this includes only KVM VMM part. For those who
are curious to changes to other component, there are public repositories at
github. [8], [9]


* Patch organization
The patch 66 is main change.  The preceding patches(1-65) The preceding
patches(01-61) are refactoring the code and introducing additional hooks.

- 01-12: They are preparations. introduce architecture constants, code
         refactoring, export symbols for following patches.
- 13-40: start to introduce the new type of VM and allow the coexistence of
         multiple type of VM. allow/disallow KVM ioctl where
         appropriate. Especially make per-system ioctl to per-VM ioctl.
- 41-65: refactoring KVM VMX/MMU and adding new hooks for Secure EPT.
- 66:    main patch to add "basic" support for building/running TDX.
- 67:    trace points for
- 68-69:  Documentation

* TODOs
Those major features are missing from this patch series to keep this patch
series small.

- load/initialize TDX module
  split out from this patch series.
- unmapping private page
  Will integrate Kirill's patch to show how kvm will utilize it.
- qemu gdb stub support
- Large page support
- guest PMU support
- TDP MMU support
- and more

Changes from v1:
- rebase to v5.13
- drop load/initialization of TDX module
- catch up the update of related specifications.
- rework on C-wrapper function to invoke seamcall
- various code clean up
