The location of the "pcrs" file is changed in newer kernels. Try running "find /sys -name pcrs". This will show the path of the "pcrs" file in newer kernels. On one of my systems, it is "/sys/devices/pnp0/00:0b/pcrs".

In the past using tboot 1.8.x and versions of trousers, tpm tools, etc, etc. that came with the distros, I was able to see the PCR values with: cat /sys/class/misc/tpm0/device/pcrs Currently I'm in CentOS 7.2 and have compliled and installed tboot 1.9.4. I see this, which with my limited knowledge base tells me something is goign right: [root@server0 ~]# txt-stat | grep measured TXT measured launch: TRUE TBOOT: measured launch succeeded [root@server0 ~]# txt-stat | grep senter senter_done: TRUE Any idea why I can't see the PCR values? ------------------------------------------------------------------------------ _______________________________________________ tboot-devel mailing list tboot-devel@lists.sourceforge.net https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.sourceforge.net_lists_listinfo_tboot-2Ddevel&d=CwICAg&c=IV_clAzoPDE253xZdHuilRgztyh_RiV3wUrLrDQYWSI&r=lDSLRzn8YUPmwjLuy9Ek9Dy-T15T3uK505eKqf1EFfg&m=NW5BjH-7UaDlGhOrxKFZY_PC9XkHbi0fJfVpYdlK_cg&s=AAL66FfeskvFTy17cL-vaa91FerkBig24cqkbMWuCxQ&e= ------------------------------------------------------------------------------ _______________________________________________ tboot-devel mailing list tboot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/tboot-devel
