The Trusted Platform Module (TPM) Interface Specification (TIS) describes the protocol for communicating with a TPM on a PC platform, including an register-based protocol over SPI. This decoder stacks on the existing SPI decoder, and decodes the TIS register transactions. Signed-off-by: Tobias Peter <[email protected]>
The Trusted Platform Module (TPM) Interface Specification (TIS) in combination with the TPM I2C Interface Specification describe the protocol for communicating with a TPM on a PC platform, including a register-based protocol over I2C. This decoder stacks on the existing I2C decoder, and decodes the TIS register transactions. Signed-off-by: Johannes Holland <[email protected]>
The Trusted Platform Module (TPM) Interface Specification (TIS) describes the protocol for communicating with a TPM on a PC platform, including a FIFO protocol based on register transactions. This decoder stacks on a TPM TIS decoder, and decodes the TPM Commands and Responses encoded in the register transactions. Signed-off-by: Tobias Peter <[email protected]>

Having more dumps of TPM data would be helpful, and test cases for sigrok-test would be extra helpful. We have some SPI TPM data in sigrokproject/sigrok-dumps#38 but no I2C or TIS at all making testing the decoder hard. |

Add decoders for the communication stack between the Trusted Platform Module (TPM) and a host machine. Included are three decoders,
tpm_tis_i2candtpm_tis_spiwhich implement register access andtpm_fifo_tiswhich implements the so-called (TPM Interface Specification) TIS protocol on top of that.The TPM commands and responses are not yet implemented, the
tpm_fifo_tisdecoder merely decodes command names and response error codes.tpm_fifo_tistpm_tis_i2c,tpm_tis_spi
