This series adds support for the full TPM 1.2 Physical Presence Interface (PPI) and activates the TPM 1.2 menu at the end. PPI is a prerequisite for the menu to work.
The modifications to the original code are mostly due to the fact that we are using a memory region for PPI in QEMU. I tried to keep them at a minimum. For the PPI Flags I am using a EFI variable just like the original code does. (SecurityPkg/Library/DxeTcgPhysicalPresenceLib/DxeTcgPhysicalPresenceLib.c) The PhysicalPresenceFlags variable is write-protected (since v3) by adding an entry to AuthVariableLib.c. The consequence of locking the variable is that the processing of the physical presence opcodes, and with that write-access to that variable, had to be moved to before the end-of-DXE because afterwards it cannot be changed anymore. Regards, Stefan v3: - Moved processing of physical presence opcodes to before end-of-DXE - Write-protected PhysicalPresenceFlags variable by entry in AuthVariableLib.c v2: - Added patch that copies sources from SecurityPkg to OvmfPkg before changes - Use CONSTRUCTOR from DxeTcgPhysicalPresenceLib.inf - Other nits Gerd Hoffmann (1): OvmfPkg: add TPM 1.2 config menu Stefan Berger (7): OvmfPkg: Move processing of physical presence opcode before End-of-Dxe OvmfPkg: Check for TPM 2 early to leave function early SecurityPkg: Store physical presence code by submitting to PreOS func SecurityPkg: Declare PhysicalPresenceFlags variable and its properties OvmfPkg: Copy TPM 1.2 DxeTcgPhysicalPresenceLib.c from SecurityPkg OvmfPkg: Enable physical presence interface for TPM 1.2 OvmfPkg: Enable TPM 1.2 Physical Presence Opcode processing OvmfPkg/Bhyve/BhyveX64.dsc | 1 + .../PlatformBootManagerLib/BdsPlatform.c | 23 +- .../PlatformBootManagerLib.inf | 1 + .../PlatformBootManagerLibBhyve/BdsPlatform.c | 20 +- .../PlatformBootManagerLibGrub/BdsPlatform.c | 20 +- .../DxeTcg2PhysicalPresenceLib.c | 36 +- .../DxeTcgPhysicalPresenceLib.c | 22 + .../DxeTcgPhysicalPresenceLib.inf | 27 + .../DxeTcgPhysicalPresenceLib.c | 1448 +++++++++++++++++ .../DxeTcgPhysicalPresenceLib.inf | 64 + .../DxeTcgPhysicalPresenceLib.uni | 22 + .../PhysicalPresenceStrings.uni | 46 + OvmfPkg/Microvm/MicrovmX64.dsc | 1 + OvmfPkg/OvmfTpmComponentsDxe.dsc.inc | 1 + OvmfPkg/OvmfTpmDxe.fdf.inc | 1 + OvmfPkg/OvmfTpmLibs.dsc.inc | 4 + OvmfPkg/OvmfXen.dsc | 1 + .../Include/Library/TcgPhysicalPresenceLib.h | 39 + .../AuthVariableLib/AuthServiceInternal.h | 1 + .../Library/AuthVariableLib/AuthVariableLib.c | 11 + .../AuthVariableLib/AuthVariableLib.inf | 4 + .../DxeTcgPhysicalPresenceLib.c | 55 + SecurityPkg/Tcg/TcgConfigDxe/TcgConfigDxe.inf | 1 + SecurityPkg/Tcg/TcgConfigDxe/TcgConfigImpl.c | 41 +- 24 files changed, 1819 insertions(+), 71 deletions(-) create mode 100644 OvmfPkg/Library/TcgPhysicalPresenceLibNull/DxeTcgPhysicalPresenceLib.c create mode 100644 OvmfPkg/Library/TcgPhysicalPresenceLibNull/DxeTcgPhysicalPresenceLib.inf create mode 100644 OvmfPkg/Library/TcgPhysicalPresenceLibQemu/DxeTcgPhysicalPresenceLib.c create mode 100644 OvmfPkg/Library/TcgPhysicalPresenceLibQemu/DxeTcgPhysicalPresenceLib.inf create mode 100644 OvmfPkg/Library/TcgPhysicalPresenceLibQemu/DxeTcgPhysicalPresenceLib.uni create mode 100644 OvmfPkg/Library/TcgPhysicalPresenceLibQemu/PhysicalPresenceStrings.uni -- 2.31.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
