gfx-portability

This is a prototype library implementing Vulkan Portability Initiative using gfx-rs low-level core. See gfx-rs meta issue for backend limitations and further details.

Vulkan CTS coverage

gfx-rs Backend	Total cases	Pass	Fail	Quality warning	Compatibility warning	Not supported	Resource error	Internal error	Timeout	Crash
Vulkan	3742	1393	101	0	0	2248	0	0	0	0
DX12	3563	1243	73	0	0	2247	0	0	0	0
Metal	3710	1260	66	0	0	2384	0	0	0	0

Currently stopping with:

Unable to create Vulkan instance: VkError(ErrorIncompatibleDriver)

Please visit our wiki for CTS hookup instructions. Once everything is set, you can generate the new results by calling make cts on Unix systems.

Check out

git clone --recursive https://github.com/gfx-rs/portability && cd portability

Build

Makefile (Unix)

make

CMake (Window)

Build the Rust library (portability implementation):

cargo build --manifest-path libportability/Cargo.toml --features <vulkan|dx12|metal>

Build the native example:

mkdir build
cd build
cmake ..
cmake --build . --target native_test

Running Samples

LunarG (API-Samples)

After building portability as shown above, grab a copy from https://github.com/LunarG/VulkanSamples. Manually override the VULKAN_LOADER variable and set it to the portability library.

set (VULKAN_LOADER "path/to/portability/library")

Then proceed with the normal build instructions.
