This does not include the actual KVM-side support which will come from the KVM folks. The TDX host interactions with kexec also needs to be ironed out before this is ready for prime time, so this code is currently Kconfig'd off when kexec is on. The majority of the code here is the kernel telling the TDX module which memory to protect and handing some additional memory over to it to use to store TDX module metadata. That sounds pretty simple, but the TDX architecture is rather flexible and it takes quite a bit of back-and-forth to say, "just protect all memory, please." There is also some code tacked on near the end of the series to handle a hardware erratum. The erratum can make software bugs such as a kernel write to TDX-protected memory cause a machine check and masquerade as a real hardware failure. The erratum handling watches out for these and tries to provide nicer user errors" * tag 'x86_tdx_for_6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits) x86/virt/tdx: Make TDX host depend on X86_MCE x86/virt/tdx: Disable TDX host support when kexec is enabled Documentation/x86: Add documentation for TDX host support x86/mce: Differentiate real hardware #MCs from TDX erratum ones x86/cpu: Detect TDX partial write machine check erratum x86/virt/tdx: Handle TDX interaction with sleep and hibernation x86/virt/tdx: Initialize all TDMRs x86/virt/tdx: Configure global KeyID on all packages x86/virt/tdx: Configure TDX module with the TDMRs and global KeyID x86/virt/tdx: Designate reserved areas for all TDMRs x86/virt/tdx: Allocate and set up PAMTs for TDMRs x86/virt/tdx: Fill out TDMRs to cover all TDX memory regions x86/virt/tdx: Add placeholder to construct TDMRs to cover all TDX memory regions x86/virt/tdx: Get module global metadata for module initialization x86/virt/tdx: Use all system memory when initializing TDX module as TDX memory x86/virt/tdx: Add skeleton to enable TDX on demand x86/virt/tdx: Add SEAMCALL error printing for module initialization x86/virt/tdx: Handle SEAMCALL no entropy error in common code x86/virt/tdx: Make INTEL_TDX_HOST depend on X86_X2APIC x86/virt/tdx: Define TDX supported page sizes as macros ... |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
