SPIR-V Tutorials

This is a repository of SPIR-V tutorials starting from the very basics. It is expected that the reader is familiar with basics of Vulkan GLSL.

This is not an officially supported Google product.

Initial Setup

These tutorials are currently only supported on Linux. Please run ./scripts/setup for initial setup. It is expected that spirv-as and spirv-val are installed on the system (usually in a spirv-tools package). Additionally, it is recommended to have the highlight command installed (from a package with the same name).

How to Follow the Tutorials

Navigate to the directory of each tutorial and follow the instructions in the README.md there. The tutorial directories are tagged with a number to indicate the intended order, for example:

01 - Introduction to SPIR-V/
02 - My First Change/
03 - My First Variable/

In the tutorials, README.md will generally introduce a new set of SPIR-V instructions and include an exercise to modify a provided SPIR-V by hand and verify the results. Solutions are provided, but it's strongly recommended not to be consulted until the exercise is complete.

Warning: passively reading the tutorials will quickly become boring. Do get your hands dirty.

When opening the SPIR-V files, it is recommended to enable some syntax highlighting for readability. With vim for example, you can install this excellent plugin, otherwise set ft=lisp is an improvement over no highlighting.

Troubleshooting

If issues with highlight are encountered, edit ./scripts/test_spirv:

• Try changing xterm256 to ansi if your terminal is not an XTERM.
• Get rid of the highlight path and live with monochrome GLSL.
