We ran the same command with both software TPM and hardware TPM.
Please find the detailed debug logs from the tcsd attached. Also copied the
relevant portions. For API GetPubKey, software TPM works fine and in thsi
case it seems an 'ioctl' call is made compared to a write in case of actual
TPM.
Software TPM:
