IntelTdx.h defines the defition used by TDX in OvmfPkg: - Mailbox related defitions,such as the data structure, command code, AP relocation defitions. See Table 5.44 Multiprocessor Wakeup Mailbox Structure in below link. https://uefi.org/specs/ACPI/6.4/05_ACPI_Software_Programming_Model/ ACPI_Software_Programming_Model.html#multiprocessor-wakeup-structure Cc: Ard Biesheuvel <ardb+tianoc...@kernel.org> Cc: Jordan Justen <jordan.l.jus...@intel.com> Cc: Brijesh Singh <brijesh.si...@amd.com> Cc: Erdem Aktas <erdemak...@google.com> Cc: James Bottomley <j...@linux.ibm.com> Cc: Jiewen Yao <jiewen....@intel.com> Cc: Tom Lendacky <thomas.lenda...@amd.com> Cc: Gerd Hoffmann <kra...@redhat.com> Acked-by: Gerd Hoffmann <kra...@redhat.com> Signed-off-by: Min Xu <min.m...@intel.com> --- OvmfPkg/Include/IndustryStandard/IntelTdx.h | 67 +++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 OvmfPkg/Include/IndustryStandard/IntelTdx.h diff --git a/OvmfPkg/Include/IndustryStandard/IntelTdx.h b/OvmfPkg/Include/IndustryStandard/IntelTdx.h new file mode 100644 index 000000000000..cc849be2fb59 --- /dev/null +++ b/OvmfPkg/Include/IndustryStandard/IntelTdx.h @@ -0,0 +1,67 @@ +/** @file + Defines the defitions used by TDX in OvmfPkg. + + Copyright (c) 2020 - 2021, Intel Corporation.
