Hello, We are running Linux under Hyper-V with its emulated vTPM (you might call it synthetic TPM). While the TPM itself adheres to the spec, it does not support localities. Consequently, the I/O block does not include the locality portion, and the control register offset is hence different in the TPM2.0 ACPI table from what the driver expects. This leads to below warning: root@ubuntu:~# dmesg | grep tpm [ 7.849077] tpm_crb VTPM0101:00: [Firmware Bug]: Bad ACPI memory layout I wonder if a warning message of the form "Memory layout does not comply to PC-client-spec. Disabling locality support." might be more descriptive, perhaps with an additional comment in the source code. What do you think? Jork
