TPM control

Thursday, 27 February 2020

I got a new computer (8GB RAM, 64-bit, AMD Ryzen 5 3550h) & managed to install Fedora
30 on it. I want to gain control of the TPM and began following
https://paolozaino.wordpress.com/2017/03/18/configure-and-use-your-tpm-mo...
for guidance. TPM does show up in the BIOS as enabled but I can't set anything about
it.

# dmesg | grep -i tpm

gives

[    0.000000] efi:  ACPI=0x8f7fe000  ACPI 2.0=0x8f7fe014  ESRT=0x8e60b998 
SMBIOS=0x8e607000  SMBIOS 3.0=0x8e605000  MEMATTR=0x7e2d4018  TPMEventLog=0x7516e018

00040000)

# systemctl status tcsd

gives

No idea what this really means.
whereis tcsd
gives
tcsd: /usr/sbin/tcsd /etc/tcsd.conf /usr/share/man/man8/tcsd.8.gz
so I have tcsd, it just isn't talking with the TPM, apparently.

# systemctl enable tcsd

gives no response, apparently succeeds.

# tpm_version

gives

Tspi_Context_Connect failed: 0x00003011 - layer=tsp, code=0011 (17), Communication
failure
This is my first rodeo with TPM and I'm trying to gain control over it so I can
reinstall an OS and boot live disks and such and not be banned from doing so by my
computer. What's wrong with TPM & how do I gain control over it?
Thanks.
