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" in coin-mining community. On Linux, the PP table is by default found at: /sys/class/drm/card0/device/pp_table.

Requirements

Python 2.7 or 3.6+, codecs, collections, struct, click. Should work on Windows as well, but modified table needs to be uploaded to registry instead of sysfs file.

Usage

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

  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

  This tool currently supports reading 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:
  -i, --pp-file <filename>  Input/output PP table binary file
  -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
  set      Set value(s) to PowerPlay parameter(s)

Dumping all data:

Usage: upp dump [OPTIONS]

  Dump all PowerPlay data to console

  De-serializes PowerPlay binary data into a Python dictionary.

  In standard mode all data will be dumped to console, where data 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

  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

  Retrieves current value of a particular PP parameter

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

      /FanTable/TargetTemperature
      /VddgfxLookupTable/7/Vdd

  The raw value of the parameter will be retrieved, decoded and displayed on
  console.

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

Setting parameters:

Usage: upp set [OPTIONS] VARIABLE_PATH_SET...

  Sets values to one or multiple PP parameters

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

      /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.

Options:
  -w, --write  Write changes to PP binary
  -h, --help   Show this message and exit.
