superiotool - Super I/O detection tool

       Please see the individual source code files and/or the README file.

       Please report any bugs on the coreboot mailing list (https://coreboot.org/Mailinglist).

superiotool is a GPL'd user-space utility which can

        * detect which Super I/O chip is soldered onto your mainboard,

        * at which configuration port it's located (usually 0x2e or 0x4e), and

        * dump all register contents of the Super I/O chip, together with the
          default values as per datasheet (to make comparing the values easy).

       It  is  mainly  used for coreboot development purposes (see coreboot.org for details on coreboot), but it
       may also be useful for other things.

       The list of supported Super I/O chips is available at https://coreboot.org/Superiotool#Supported_devices,
       but it can also be viewed by running superiotool-l.

superiotool is covered by the GNU General Public License (GPL), either version 2 of the License,  or  (at
       your option) any later version.

       superiotool - Super I/O detection tool

       If no command line option is specified, superiotool merely tries to detect the Super I/O chip.  You  must
       use the -d option to dump the Super I/O register contents.

       -d,--dump
              Dump  Super  I/O  registers (if the Super I/O chip is detected and superiotool supports the --dump
              option for this chip). The output will look something like this:

              $superiotool-d
              Found SMSC FDC37N769 (id=0x28, rev=0x01) at 0x3f0
              Register dump:
              idx 00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10 11...
              val 20 90 80 f4 00 00 ff 00 00 00 40 00 0e 28 01 00 00 00...
              def 28 9c 88 70 00 00 ff 00 00 00 00 00 02 28 NA 00 00 80...

              The idx fields contain the register numbers/indexes of the Super I/O, the val fields  contain  the
              contents  of  the  respective  register as read from the Super I/O, and the def fields contain the
              default values for the respective register, as specified in the datasheet.

              The numbers in the output are all in hex format, and some special values may also occur: NA stands
              for notavailable (i.e., the  datasheet  doesn't  specify  a  default  value  for  the  respective
              register),  RR  means  reserved (the datasheet explicitly marks this register as reserved), and MM
              means misc, which can mean several things. It's recommended to consult the datasheet for  detailed
              information about the MM fields.

       -e,--extra-dump
              Dump  extra  secondary  register  contents  too, if available. Only in combination with the --dump
              option. This option will, for instance,  dump  the  environmental  controller  (EC)  configuration
              registers for the ITE IT8716F chip. The format is similar to the output of the --dump option.

       -l,--list-supported
              List  all  Super I/O chips recognized by superiotool. The phrase (dumpavailable) following a chip
              name indicates that superiotool supports the --dump option for this chip.

       -V,--verbose
              Enable verbose mode. This option can be used together with the -d option.

              The verbose output will not only list for which type of Super I/O the tool is scanning,  but  also
              at  which configuration port it's probing, and which Super I/O initialization sequence is used. If
              no Super I/O was detected in a probing run, the returned output will be shown, as it may be useful
              for figuring out which (currently unrecognized) Super I/O chip this may be.

       -v,--version
              Show version information and exit.

       -h,--help
              Show a help text and exit.
