tpm: Move backend code under the 'backends/' directory

2020-06-19T11:25:55+00:00

TPM subsytem is split into backends (see commit f4ede81eed2) and frontends (see i.e. 3676bc69b35). Keep the emulated hardware 'frontends' under hw/tpm/, but move the backends in the backends/tpm/ directory.

tpm_spapr: Support TPM for ppc64 using CRQ based interface

2020-02-02T03:07:57+00:00

Implement support for TPM on ppc64 by implementing the vTPM CRQ interface as a frontend. It can use the tpm_emulator driver backend with the external swtpm. The Linux vTPM driver for ppc64 works with this emulation. This TPM emulator also handles the TPM 2 case.

tpm: allocate/map buffer for TPM Physical Presence interface

2019-01-18T02:10:57+00:00

Implement a virtual memory device for the TPM Physical Presence interface. The memory is located at 0xFED45000 and used by ACPI to send messages to the firmware (BIOS) and by the firmware to provide parameters for each one of the supported codes. This interface should be used by all TPM devices on x86 and can be added by calling tpm_ppi_init_io(). Note: bios_linker cannot be used to allocate the PPI memory region, since the reserved memory should stay stable across reboots, and might be needed before the ACPI tables are installed.

tpm: add CRB device

2018-01-29T19:22:50+00:00

tpm_crb is a device for TPM 2.0 Command Response Buffer (CRB) Interface as defined in TCG PC Client Platform TPM Profile (PTP) Specification Family “2.0” Level 00 Revision 01.03 v22. The PTP allows device implementation to switch between TIS and CRB model at run time, but given that CRB is a simpler device to implement, I chose to implement it as a different device. The device doesn't implement other locality than 0 for now (my laptop TPM doesn't either, so I assume this isn't so bad) Tested with some success with Linux upstream and Windows 10, seabios & modified ovmf. The device is recognized and correctly transmit command/response with passthrough & emu. However, we are missing PPI ACPI part atm.
