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.
You can passthrough a TPM 2.0 device with the qemu TIS interface. This should work ok with a Linux guest.
Is your TPM 2.0 device correctly working on the host?
