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.

Best Reagrds,
