History
Richard Hughes 2e1245728f Call the superclass directly from subclassed devices 
This allows a device subclass to call the parent method after doing an initial
action, or even deliberately not call the *generic* parent method at all.

It also simplifies the plugins; you no longer have to remember what the plugin
is deriving from and accidentally clobber the wrong superclass method.

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.

External interface access

This plugin uses the tpm2-tss library to access the TPM. It requires access to /sys/class/tpm.
