![]() The fact that it currently lives in uefi-capsule is a historical accident, and it doesn't really belong to tpm-eventlog either. Fixes some of https://github.com/fwupd/fwupd/issues/3901 |

TPM
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
.
