Subject: [PATCH v4 00/10] Add TDX Guest Support (#VE handler support)
Date: Wed,  4 Aug 2021 12:18:45 -0700	[thread overview]
Message-ID: <20210804191855.2901927-1-sathyanarayanan.kuppuswamy@linux.intel.com> (raw)

Hi All,

Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious
hosts and some physical attacks. This series adds #VE handler support,
for port I/O, MMIO and MWAIT/MONITOR features in TDX guest.

This series is the continuation of the patch series titled "Add TDX Guest
Support (Initial support)" which added initial support for TDX guests. You
can find the patchset in the following link.

[set 1, v5] - https://lore.kernel.org/patchwork/project/lkml/list/?series=510805

Also please note that this series alone is not necessarily fully
functional.

You can find TDX related documents in the following link.

https://software.intel.com/content/www/br/pt/develop/articles/intel-trust-domain-extensions.html

Changes since v3:
 * Rebased on top of Tom Lendacky protected guest changes.
 * Rest of changelogs are included in patches in-line.

Changes since v2:
 * Rebased on top of v5.14-rc1.
 * Rest of changelogs are included in patches in-line.

Changes since v1:
 * Rebased on top of TDX guest set 1 patches (which had some core API changes).
 * Moved "x86/tdx: Add early_is_tdx_guest() interface" patch from set 1 patch
   series to this patchset (since it is only used in early I/O support case).
 * Rest of changelogs are included in patches in-line.
