https://trustedcomputinggroup.org/tcg-acpi-specification/
== ACPI PPI Interface ==
QEMU supports the Physical Presence Interface (PPI) for TPM 1.2 and TPM 2. This
interface requires ACPI and firmware support. The specification can be found at
the following URL:
https://trustedcomputinggroup.org/resource/tcg-physical-presence-interface-specification/
PPI enables a system administrator (root) to request a modification to the
TPM upon reboot. The PPI specification defines the operation requests and the
actions the firmware has to take. The system administrator passes the operation
request number to the firmware through an ACPI interface which writes this
number to a memory location that the firmware knows. Upon reboot, the firmware
finds the number and sends commands to the the TPM. The firmware writes the TPM
result code and the operation request number to a memory location that ACPI can
read from and pass the result on to the administrator.
The PPI specification defines a set of mandatory and optional operations for
the firmware to implement. The ACPI interface also allows an administrator to
list the supported operations. In QEMU the ACPI code is generated by QEMU, yet
the firmware needs to implement support on a per-operations basis, and
different firmwares may support a different subset. Therefore, QEMU introduces
the virtual memory device for PPI where the firmware can indicate which
operations it supports and ACPI can enable the ones that are supported and
disable all others. This interface lies in main memory and has the following
layout:
+----------+--------+--------+-------------------------------------------+
| Field | Length | Offset | Description |
+----------+--------+--------+-------------------------------------------+
| func | 0x100 | 0x000 | Firmware sets values for each supported |
| | | | operation. See defined values below. |
+----------+--------+--------+-------------------------------------------+
| ppin | 0x1 | 0x100 | SMI interrupt to use. Set by firmware. |
| | | | Not supported. |
+----------+--------+--------+-------------------------------------------+
| ppip | 0x4 | 0x101 | ACPI function index to pass to SMM code. |
| | | | Set by ACPI. Not supported. |
+----------+--------+--------+-------------------------------------------+
| pprp | 0x4 | 0x105 | Result of last executed operation. Set by |
| | | | firmware. See function index 5 for values.|
+----------+--------+--------+-------------------------------------------+
| pprq | 0x4 | 0x109 | Operation request number to execute. See |
| | | | 'Physical Presence Interface Operation |
| | | | Summary' tables in specs. Set by ACPI. |
+----------+--------+--------+-------------------------------------------+
| pprm | 0x4 | 0x10d | Operation request optional parameter. |
| | | | Values depend on operation. Set by ACPI. |
+----------+--------+--------+-------------------------------------------+
| lppr | 0x4 | 0x111 | Last executed operation request number. |
| | | | Copied from pprq field by firmware. |

| | | | firmware. Used by firmware. |
+----------+--------+--------+-------------------------------------------+
| movv | 0x1 | 0x15a | Memory overwrite variable |
+----------+--------+--------+-------------------------------------------+
The following values are supported for the 'func' field. They correspond
to the values used by ACPI function index 8.
+----------+-------------------------------------------------------------+
| value | Description |
+----------+-------------------------------------------------------------+
| 0 | Operation is not implemented. |
+----------+-------------------------------------------------------------+
| 1 | Operation is only accessible through firmware. |
+----------+-------------------------------------------------------------+
| 2 | Operation is blocked for OS by firmware configuration. |
+----------+-------------------------------------------------------------+
| 3 | Operation is allowed and physically present user required. |
+----------+-------------------------------------------------------------+
| 4 | Operation is allowed and physically present user is not |
| | required. |
+----------+-------------------------------------------------------------+
The location of the table is given by the fw_cfg tpmppi_address field.
The PPI memory region size is 0x400 (TPM_PPI_ADDR_SIZE) to leave
enough room for future updates.
