VK_KHR_portability_subset Validation

Requirements

Either

• The VK_LAYER_LUNARG_device_simulation layer with portability enabled or
• A driver that supports VK_KHR_portability_subset.

Running the tests

The following is an example setup for running the portability tests on Windows with devsim:

# Replace ';' with ':' when running on *nix
$env:VK_LAYER_PATH="/path/to/VulkanTools/build/layersvt/Debug;/path/to/Vulkan-ValidationLayers/build/layers/Debug"

# Make sure the devsim layer is loaded.
# Again be sure to replace ';' with ':' when running on *nix.
$env:VK_INSTANCE_LAYERS="VK_LAYER_KHRONOS_validation;VK_LAYER_LUNARG_device_simulation"

# This environment variable must be set to ensure portability is enabled as there is currently no programatic way to enable portability in the devsim layer
$env:VK_DEVSIM_EMULATE_PORTABILITY_SUBSET_EXTENSION="1"
