PPI test runs successfully with Windows 10 WHLK, despite the limited number of supported funcions (tpm2_ppi_funcs table, in particular, no function allows to manipulate Tcg2PhysicalPresenceFlags) The way it works is relatively simple: a memory region is allocated by QEMU to save PPI related variables. An ACPI interface is exposed by QEMU to let the guest manipulate those. At boot, ovmf processes and updates the PPI qemu region and request variables. I build edk2 with: $ build -DTPM2_ENABLE -DSECURE_BOOT_ENABLE I test with qemu & swtpm/libtpms (tpm2 branches, swtpm_setup.sh --tpm2 --tpm-state tpmstatedir) $ swtpm socket --tpmstate tpmstatedir --ctrl type=unixio,path=tpmsock --tpm2 & $ qemu .. -chardev socket,id=chrtpm,path=tpmsock -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-crb,tpmdev=tpm0 Github trees: https://github.com/elmarco/edk2/tree/tpm-ppi https://github.com/elmarco/qemu/tree/tpm-ppi Thanks v2: - style and commit message fixes Marc-André Lureau (4): OvmfPkg: add Tcg2PhysicalPresenceLibNull when !TPM2_ENABLE OvmfPkg/IndustryStandard: add QemuTpm.h header OvmfPkg: add Tcg2PhysicalPresenceLibQemu OvmfPkg/PlatformBootManagerLib: process TPM PPI request OvmfPkg/OvmfPkgIa32.dsc | 4 +- OvmfPkg/OvmfPkgIa32X64.dsc | 4 +- OvmfPkg/OvmfPkgX64.dsc | 4 +- .../PlatformBootManagerLib.inf | 2 + .../DxeTcg2PhysicalPresenceLib.inf | 34 + .../DxeTcg2PhysicalPresenceLib.inf | 25 +- OvmfPkg/Include/IndustryStandard/QemuTpm.h | 69 ++ .../PlatformBootManagerLib/BdsPlatform.c | 8 + .../DxeTcg2PhysicalPresenceLib.c | 19 +- .../DxeTcg2PhysicalPresenceLib.c | 889 ++++++++++++++++++ .../DxeTcg2PhysicalPresenceLib.uni | 3 +- .../PhysicalPresenceStrings.uni | 28 +- 12 files changed, 1039 insertions(+), 50 deletions(-) create mode 100644 OvmfPkg/Library/Tcg2PhysicalPresenceLibNull/DxeTcg2PhysicalPresenceLib.inf copy {SecurityPkg/Library/DxeTcg2PhysicalPresenceLib => OvmfPkg/Library/Tcg2PhysicalPresenceLibQemu}/DxeTcg2PhysicalPresenceLib.inf (80%) create mode 100644 OvmfPkg/Include/IndustryStandard/QemuTpm.h copy EdkCompatibilityPkg/Foundation/Library/EdkIIGlueLib/Library/BaseLib/Ia32/CpuSleep.c => OvmfPkg/Library/Tcg2PhysicalPresenceLibNull/DxeTcg2PhysicalPresenceLib.c (55%) create mode 100644 OvmfPkg/Library/Tcg2PhysicalPresenceLibQemu/DxeTcg2PhysicalPresenceLib.c copy {SecurityPkg/Library/DxeTcg2PhysicalPresenceLib => OvmfPkg/Library/Tcg2PhysicalPresenceLibQemu}/DxeTcg2PhysicalPresenceLib.uni (97%) copy {SecurityPkg/Library/DxeTcg2PhysicalPresenceLib => OvmfPkg/Library/Tcg2PhysicalPresenceLibQemu}/PhysicalPresenceStrings.uni (62%) -- 2.17.0.253.g3dd125b46d
