[Qemu-devel] [PATCH v3 0/4] Add support for TPM Physical Presence interface
Posted by Marc-André Lureau 5 years, 10 months ago
Hi,

The following patches implement the TPM Physical Presence Interface
that allows a user to set a command via ACPI (sysfs entry in Linux)
that, upon the next reboot, the firmware looks for and acts upon by
sending sequences of commands to the TPM.

A dedicated memory region is added to the TPM CRB & TIS devices, at
address/size 0xFED45000/0x400. A new "etc/tpm/config" fw_cfg entry
holds the location for that PPI region and some version details, to
allow for future flexibility.

With the associated edk2/ovmf firmware, the Windows HLK "PPI 1.3" test
now runs successfully.

It is based on previous work from Stefan Berger ("[PATCH v2 0/4]
Implement Physical Presence interface for TPM 1.2 and 2")

Git branches:
https://github.com/elmarco/qemu tpm-ppi
https://github.com/elmarco/edk2 tpm-ppi

Marc-André Lureau (1):
  tpm: add a fake ACPI memory clear interface

Stefan Berger (3):
  tpm: implement virtual memory device for TPM PPI
  acpi: add fw_cfg file for TPM and PPI virtual memory device
  acpi: build TPM Physical Presence interface
