Project description

UPP

UPP: Uplift Power Play

A tool for parsing, dumping and modifying data in Radeon PowerPlay tables

Introduction

UPP is able to parse and modify binary data structures of PowerPlay tables commonly found on certain AMD Radeon GPUs. Drivers on recent AMD GPUs allow PowerPlay tables to be dynamically modified on runtime, which may be known as "soft" PowerPlay table. On Linux, the PowerPlay table is by default found at: /sys/class/drm/card0/device/pp_table.

Requirements

Python 2.7 or 3.6+, click library. Optionally, for reading "soft" PowerPlay table from Windows registry: python-registry. Should work on Windows as well (testers wanted).

Usage

At its current form this is a CLI only tool. Getting help:

Usage: upp [OPTIONS] COMMAND [ARGS]...

  UPP: Uplift Power Play

  A tool for parsing, dumping and modifying data in Radeon PowerPlay tables.

  UPP is able to parse and modify binary data structures of PowerPlay tables
  commonly found on certain AMD Radeon GPUs. Drivers on recent AMD GPUs
  allow PowerPlay tables to be dynamically modified on runtime, which may be
  known as "soft PowerPlay tables". On Linux, the PowerPlay table is by
  default found at:

     /sys/class/drm/card0/device/pp_table

  There are also two alternative ways of getting PowerPlay data that this
  tool supports:

   - By extracting PowerPlay table from Video ROM image (see extract command)
   - Import "Soft PowerPlay" table from Windows registry, directly from
     offline Windows/System32/config/SYSTEM file on disk, so it would work
     from Linux distro that has acces to mounted Windows partition
     (path to SYSTEM registry file is specified with --from-registry option)

  This tool currently supports parsing and modifying PowerPlay tables found
  on the following AMD GPU families:

    - Polaris
    - Vega
    - Radeon VII
    - Navi 10
    - Navi 14

  Note: iGPUs found in many recent AMD APUs are using completely different
  PowerPlay control methods, this tool does not support them.

Options:
  -p, --pp-file <filename>        Input/output PP table binary file.
  -f, --from-registry <filename>  Import PP_PhmSoftPowerPlayTable from Windows
                                  registry (overrides -p / --pp-file option).
  -d, --debug / --no-debug        Debug mode.
  -h, --help                      Show this message and exit.

Commands:
  dump     Dumps all PowerPlay parameters to console.
  extract  Extract PowerPlay table from Video BIOS ROM image.
  get      Get current value of a PowerPlay parameter(s).
  set      Set value to PowerPlay parameter(s).

Dumping all data:

Usage: upp dump [OPTIONS]

  Dump all PowerPlay data to console

  De-serializes PowerPlay binary data into a human-readable text output. For
  example:

      upp --pp-file=radeon.pp_table dump

  In standard mode all data will be dumped to console, where data tree
  hierarchy is indicated by indentation.

  In raw mode a table showing all hex and binary data, as well as variable
  names and values, will be dumped.

Options:
  -r, --raw / --no-raw  Show raw binary data.
  -h, --help            Show this message and exit.

Extracting PowerPlay table from Video ROM image:

Usage: upp extract [OPTIONS]

  Extracts PowerPlay data from full VBIOS ROM image

  The source video ROM binary must be specified with -r/--video-rom
  parameter, and extracted PowerPlay table will be saved into file specified
  with -p/--pp-file. For example:

      upp --pp-file=extracted.pp_table extract -r VIDEO.rom

  Default output file name will be an original ROM file name with an
  additional .pp_table extension.

Options:
  -r, --video-rom <filename>  Input Video ROM binary image file  [required].
  -h, --help                  Show this message and exit.

Getting parameter:

Usage: upp get [OPTIONS] VARIABLE_PATH_SET...

  Retrieves current value of one or multiple PP parameters

  The parameter variable path must be specified in "/<param> notation", for
  example:

      upp get /FanTable/TargetTemperature /VddgfxLookupTable/7/Vdd

  The raw value of the parameter will be retrieved, decoded and displayed on
  console. Multiple PP parameters can be specified at the same time.

Options:
  -h, --help  Show this message and exit.

Setting parameters:

Usage: upp set [OPTIONS] VARIABLE_PATH_SET...

  Sets value to one or multiple PP parameters

  The parameter path and value must be specified in "/<param>=<value>
  notation", for example:

      upp set /PowerTuneTable/TDP=75 /SclkDependencyTable/7/Sclk=107000

  Multiple PP parameters can be set at the same time. The PP tables will not
  be changed unless additional --write option is set.

  Optionally, if --to-reg output is used an additional Windows registry
  format file will be generated, named same as PowerPlay output target
  filename with an additional '.reg' extension.

Options:
  -t, --to-reg  Save output to Windows registry .reg file as well.
  -w, --write   Write changes to PP binary.
  -h, --help    Show this message and exit.
