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!

Subdirectories:

• 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

Dependencies:

• cmake
• libxml2
• flex
• bison
• pkg-config

Optional dependencies needed by hwtest:

• libpciaccess

Optional dependencies needed by demmt:

• libdrm (nouveau)
• libseccomp

Optional dependencies needed by nva:

• libpciaccess
• libx11
• libxext
• python3
• cython3

Optional dependencies needed by vdpow:

• libpciaccess
• libx11
• vdpau

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

• ninja

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:

• Hwtest: -DDISABLE_HWTEST=ON
• Nva: -DDISABLE_NVA=ON
• VDPOW: -DDISABLE_VDPOW=ON
