TPM Support
|
|
===========
|
|
|
|
Introduction
|
|
------------
|
|
|
|
This allows enumerating Trusted Platform Modules, also known as "TPM" devices,
|
|
although it does not allow the user to update the firmware on them.
|
|
|
|
GUID Generation
|
|
---------------
|
|
|
|
These devices use custom GUIDs:
|
|
|
|
|
|
* `TPM\VEN_$(manufacturer)&DEV_$(type)`
|
|
* `TPM\VEN_$(manufacturer)&MOD_$(vendor-string)`
|
|
* `TPM\VEN_$(manufacturer)&DEV_$(type)_VER_$(family)`,
|
|
* `TPM\VEN_$(manufacturer)&MOD_$(vendor-string)_VER_$(family)`
|
|
|
|
...where `family` is either `2.0` or `1.2`
|
|
|
|
Example GUIDs from a real system containing a TPM from Intel:
|
|
```
|
|
Guid: 34801700-3a50-5b05-820c-fe14580e4c2d <- TPM\VEN_INTC&DEV_0000
|
|
Guid: 03f304f4-223e-54f4-b2c1-c3cf3b5817c6 <- TPM\VEN_INTC&DEV_0000&VER_2.0
|
|
```
|
|
|
|
Vendor ID Security
|
|
------------------
|
|
|
|
The device is not upgradable and thus requires no vendor ID set.
