Subject[PATCH v1 0/4] Add TDX Guest Support (Debug support)
Date
Hi All,

Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious
hosts and some physical attacks.

Following patches adds tracepoint support for TDX Guest TDCALL requests
and #VE exceptions. It also includes helper function to detect TD-DEBUG
mode which will be used by patches in other TDX series to add TD-DEBUG
mode specific features support.

This series is the continuation of the following TDX guest related patches.

[set 1] - https://lore.kernel.org/patchwork/project/lkml/list/?series=505232
[set 2] - https://lore.kernel.org/patchwork/project/lkml/list/?series=506230
[set 3] - https://lore.kernel.org/patchwork/project/lkml/list/?series=506231
[set 4] - https://lore.kernel.org/patchwork/project/lkml/list/?series=506232

Also please note that this series alone is not necessarily fully
functional. You need to apply all the above 4 patch series to get
a fully functional TDX guest.
