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