NAME¶

tpm2_rc_decode(1) - Decode TPM2 error codes to a human readable format.

SYNOPSIS¶

tpm2_rc_decode [OPTIONS] [ARGUMENT]

DESCRIPTION¶

tpm2_rc_decode(1) - Converts an RC_CODE from the TPM or TSS2 software stack into human readable errors. Analogous to strerror(3), but for the TPM2 stack.

OPTIONS¶

This tool takes no tool specific options.

•

ARGUMENT the command line argument specifies the error code to be parsed.

COMMON OPTIONS¶

This collection of options are common to many programs and provide information that many users may expect.

•

-h, --help=[man|no-man]: Display the tools manpage. By default, it attempts to invoke the manpager for the tool, however, on failure will output a short tool summary. This is the same behavior if the “man” option argument is specified, however if explicit “man” is requested, the tool will provide errors from man on stderr. If the “no-man” option if specified, or the manpager fails, the short options will be output to stdout.

•

-v, --version: Display version information for this tool, supported tctis and exit.

•

-V, --verbose: Increase the information that the tool prints to the console during its execution. When using this option the file and line number are printed.

•

-Q, --quiet: Silence normal tool output to stdout.

•

-Z, --enable-errata: Enable the application of errata fixups. Useful if an errata fixup needs to be applied to commands sent to the TPM. Defining the environment TPM2TOOLS_ENABLE_ERRATA is equivalent. information many users may expect.

EXAMPLES¶

tpm2_rc_decode 0x1d5
tpm:parameter(1):structure is the wrong size
