tpm: TPM 2 support - SeaBIOS

19 Oct 2017


      Hello,
    I am using the seabios-1.10.0 with qemu2.6, I know seabios-1.10.0 supports TPM2.0, but unfortunately it doesn’t work for me. I have tested CentOS 7.2 and Ubuntu 14.04, it all said: 
    “ima: NO TPM chip found, activating TPM-bypass!”
    I doubt it’s a problem about TPM driver, so I download the Ubuntu kernel source code, and I find the interface as follows:
--- TPM Hardware Support
-*-    TPM Interface Specification 1.2 Interface / TPM 2.0 FIFO Interface
<M>    TPM Interface Specification 1.2 Interface (I2C - Atmel)
<M>    TPM Interface Specification 1.2 Interface (I2C -Infineon)
<M>    TPM Interface Specification 1.2 Interface (I2C - Muvoton)
<M>    National Semiconductor TPM Interface
<M>    Atmel TPM Interface
<M>    Infineon Technologies TPM Interface
<M>    XEN TPM Interface
< >    TPM 2.0 CRB Interface
< >    STMicroelectronics TPM Interface Specification 1.2 Interface
---
    Should I need open the TPM 2.0 CRB Interface? I really hope you could give me some advice.
