x86/sev: Move SEV compilation unitsA long time ago it was agreed upon that the coco stuff needs to go whereit belongs: https://lore.kernel.org/all/Yg5nh1RknPRwIrb8@zn.tnicand not keep it in arch/x86/kernel. TDX did that and SEV can't find timeto do so. So lemme do it. If people have trouble converting theirongoing featuritis patches, ask me for a sed script.No functional changes.Move the instrumentation exclusion bits too, as helpfully caught andreported by the 0day folks.Closes: https://lore.kernel.org/oe-kbuild-all/202406220748.hG3qlmDx-lkp@intel.comReported-by: kernel test robot Closes: https://lore.kernel.org/oe-lkp/202407091342.46d7dbb-oliver.sang@intel.comReported-by: kernel test robot Signed-off-by: Borislav Petkov (AMD) Reviewed-by: Nikunj A Dadhania Reviewed-by: Ashish Kalra Tested-by: kernel test robot Link: https://lore.kernel.org/r/20240619093014.17962-1-bp@kernel.org List of files: /linux-6.15/arch/x86/coco/Makefile

59bd54a8 - x86/tdx: Detect running as a TDX guest in early boot

Tue, 05 Apr 2022 23:29:10 +0000

x86/tdx: Detect running as a TDX guest in early bootIn preparation of extending cc_platform_has() API to support TDX guest,use CPUID instruction to detect support for TDX guests in the earlyboot code (via tdx_early_init()). Since copy_bootdata() is the firstuser of cc_platform_has() API, detect the TDX guest status before it.Define a synthetic feature flag (X86_FEATURE_TDX_GUEST) and set thisbit in a valid TDX guest platform.Signed-off-by: Kuppuswamy Sathyanarayanan Signed-off-by: Kirill A.

x86/cc: Move arch/x86/{kernel/cc_platform.c => coco/core.c}Move cc_platform.c to arch/x86/coco/. The directory is going to be thehome space for code related to confidential computing.Intel TDX code will land here. AMD SEV code will also eventually bemoved there.No functional changes.Signed-off-by: Kirill A.
