Merge tag 'x86_tdx_for_6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tipPull x86 TDX updates from Dave Hansen: "The majority of this is a rework of the assembly and C wrappers that are used to talk to the TDX module and VMM. This is a nice cleanup in general but is also clearing the way for using this code when Linux is the TDX VMM. There are also some tidbits to make TDX guests play nicer with Hyper-V and to take advantage the hardware TSC. Summary: - Refactor and clean up TDX hypercall/module call infrastructure - Handle retrying/resuming page conversion hypercalls - Make sure to use the (shockingly) reliable TSC in TDX guests"[ TLA reminder: TDX is "Trust Domain Extensions", Intel's guest VM confidentiality technology ]* tag 'x86_tdx_for_6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/tdx: Mark TSC reliable x86/tdx: Fix __noreturn build warning around __tdx_hypercall_failed() x86/virt/tdx: Make TDX_MODULE_CALL handle SEAMCALL #UD and #GP x86/virt/tdx: Wire up basic SEAMCALL functions x86/tdx: Remove 'struct tdx_hypercall_args' x86/tdx: Reimplement __tdx_hypercall() using TDX_MODULE_CALL asm x86/tdx: Make TDX_HYPERCALL asm similar to TDX_MODULE_CALL x86/tdx: Extend TDX_MODULE_CALL to support more TDCALL/SEAMCALL leafs x86/tdx: Pass TDCALL/SEAMCALL input/output registers via a structure x86/tdx: Rename __tdx_module_call() to __tdcall() x86/tdx: Make macros of TDCALLs consistent with the spec x86/tdx: Skip saving output regs when SEAMCALL fails with VMFailInvalid x86/tdx: Zero out the missing RSI in TDX_HYPERCALL macro x86/tdx: Retry partially-completed page conversion hypercalls List of files: /linux/arch/x86/virt/vmx/Makefile

c33621b4c5ad5b6b8b245754013cc506f9ded2b8 - x86/virt/tdx: Wire up basic SEAMCALL functions

Tue, 15 Aug 2023 11:02:04 +0000

x86/virt/tdx: Wire up basic SEAMCALL functionsIntel Trust Domain Extensions (TDX) protects guest VMs from malicioushost and certain physical attacks. A CPU-attested software modulecalled 'the TDX module' runs inside a new isolated memory range as atrusted hypervisor to manage and run protected VMs.TDX introduces a new CPU mode: Secure Arbitration Mode (SEAM). Thismode runs only the TDX module itself or other code to load the TDXmodule.The host kernel communicates with SEAM software via a new SEAMCALLinstruction. This is conceptually similar to a guest->host hypercall,except it is made from the host to SEAM software instead. The TDXmodule establishes a new SEAMCALL ABI which allows the host toinitialize the module and to manage VMs.The SEAMCALL ABI is very similar to the TDCALL ABI and leverages muchTDCALL infrastructure. Wire up basic functions to make SEAMCALLs forthe basic support of running TDX guests: __seamcall(), __seamcall_ret(),and __seamcall_saved_ret() for TDH.VP.ENTER. All SEAMCALLs involved inthe basic TDX support don't use "callee-saved" registers as input andoutput, except the TDH.VP.ENTER.To start to support TDX, create a new arch/x86/virt/vmx/tdx/tdx.c forTDX host kernel support. Add a new Kconfig option CONFIG_INTEL_TDX_HOSTto opt-in TDX host kernel support (to distinguish with TDX guest kernelsupport). So far only KVM uses TDX. Make the new config option dependon KVM_INTEL.Signed-off-by: Kai Huang Signed-off-by: Dave Hansen Reviewed-by: Kirill A.
