tss2_nvsetbits(1)

NAME
tss2_nvsetbits(1) -

SYNOPSIS
tss2_nvsetbits [OPTIONS]

SEE ALSO
fapi-config(5) to adjust Fapi parameters like the used cryptographic profile and TCTI or directories for the Fapi metadata storages.

fapi-profile(5) to determine the cryptographic algorithms and parameters for all keys and operations of a specific TPM interaction like the name hash algorithm, the asymmetric signature algorithm, scheme and parameters and PCR bank selection.

DESCRIPTION
tss2_nvsetbits(1) - This command sets bits in an NV Index that was created as a bit field. Any number of bits from 0 to 64 may be set. The contents of bitmap are ORed with the current contents of the NV Index.

OPTIONS
These are the availabe options:

•   -i, --bitmap=BITS:

    A mask indicating which bits to set in the NV space.

•   -p, --nvPath=STRING:

    Identifies the NV space to write.

COMMON OPTIONS
This collection of options are common to all tss2 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.

    To successfully use the manpages feature requires the manpages to be installed or on MANPATH, See man(1) for more details.

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

EXAMPLE

        tss2_nvsetbits --nvPath=/nv/Owner/NvBitmap --bitmap=0x0102030405060608

RETURNS
0 on success or 1 on failure.
