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, v8] - https://lore.kernel.org/lkml/20211005025205.1784480-1-sathyanarayanan.kuppuswamy@linux.intel.com/ 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 v6: * Included section titles in spec references Changes since v5: * Rebased on top of v5.15-rc1. * Rebased on top of Tom Landeckys latest CC support patches. Changes since v4: * Renamed tdg_ prefix to tdx_. * Rest of changelogs are included in patches in-line. 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.
