如何檢查機器是否支持tpm

TPMs don’t necessarily appear in the ACPI tables, but the modules do print a message when they find a supported module;Sodmesg | grep -i tpmis a good indicator.

dmesg | grep -i tpm

如果有

[  134.026892] tpm_tis 00:08: 1.2 TPM (device-id 0xB, rev-id 16)

或者

[    0.000000] efi:  ACPI 2.0=0x69cb0000  ACPI=0x69cb0000  TPMFinalLog=0x69cf2000  SMBIOS=0x69f71000  SMBIOS 3.0=0x69f70000  ESRT=0x69f4c818  MEMATTR=0x63421098  TPMEventLog=0x5f828018 
[    0.006922] ACPI: TPM2 0x0000000069CC3940 000034 (v03 INTEL  NUC7CJYB 00000001 AMI  00000000)

如果沒有

[    0.900526] ima: No TPM chip found, activating TPM-bypass! (rc=-19)
