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