Patch Set #1, Line 900: acpigen_write_name_string("_HID", "MSFT0101");
the TPM spec says that either _HID or _CID must be MSFT0101. […]
Hmm, maybe you are looking on an outdated spec:
```
8.1 ACPI Device Object for TPM
A TPM device object MUST contain
a. a _HID object with a value that is formatted according to the ACPI Specification
and contains the manufacturer ID of the TPM vendor and a unique identifier and
is in the format “AAA####” or “NNNN####”, and
b. a _CID object with the value of “MSFT0101” or evaluate to a package where the
2515 value “MSFT0101” is one of the IDs within the package, or
c. A TPM device object MUST contain a _HID object with the value of “MSFT0101”
```
Point b says CID must be MSFT0101. Point c says HID must be MSFT0101
