envytools

Tools for people envious of nvidia's blob driver.

The canonical repo is at: https://github.com/envytools/envytools/. Pushing anywhere else will result in a de-facto fork!

docs: plain-text documentation of the GPUs, nVidia binary driver, and the tools (in-sync HTML version at https://envytools.readthedocs.io)
envydis: Disassembler and assembler for various ISAs found on nvidia GPUs
rnn: Tools and libraries for the rules-ng-ng XML register database format
rnndb: rnn database of nvidia MMIO registers, FIFO methods, and memory structures.
nvbios: Tools to decode the card description structures found in nvidia VBIOS
nva: Tools to directly access the GPU registers
vstream: Tools to decode and encode raw video bitstreams
vdpow: A tool aiding in VP3 reverse engineering
easm: Utility code dealing with assembly language parsing & printing.
util: Misc utility code shared between envytools modules

Building, installing

Dependencies:

Optional dependencies needed by hwtest:

Optional dependencies needed by demmt:

Optional dependencies needed by nva:

Optional dependencies needed by vdpow:

Optional dependencies needed for ninja build (faster recompile times):

If your distribution has -dev or -devel packages, you'll also need ones corresponding to the dependencies above.

On ubuntu it can be done like this:

apt-get install cmake flex libpciaccess-dev bison libx11-dev libxext-dev libxml2-dev libvdpau-dev python3-dev cython3

To build using ninja (recommended if you work on envytools):

$ cmake . -G Ninja
$ ninja

If you prefer to stay with make, use

$ cmake .
$ make

To install [which is optional], use

$ ninja install

or

$ make install

If you want to install to a non-default directory, you'll also need to pass it as an option to cmake before building, eg.:

$ cmake -D CMAKE_INSTALL_PREFIX:PATH=/usr/local .

If you don't want to compile some parts of envytools, you can pass the following options to cmake:
