gfx-portability

Build Status Gitter

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 7759 2155 131 34 0 5439 0 0 0 0
DX12 3576 1258 70 0 0 2248 0 0 0 0
Metal 7687 2072 112 39 0 5464 0 0 0 0

Current blockers:

  • Vulkan: "api.command_buffers.render_pass_continue" (secondary render passes).
  • DX12: lack of VkBufferView implementation.
  • Metal: "api.buffer_view.access.suballocation.buffer_view_memory_test_complete" (missing R32Uint support).

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. When investigating a particular failure, it's handy to do make cts debug=<test_name>, which runs a single test under system debugger (gdb/lldb). For simply inspecting the log output, one can also do make cts pick=<test_name>.

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.
