Is it possible to disable Vulkan extensions for debugging purposes? If so, how?

[CNR0706]

I am trying to debug a performance regression related to VK_EXT_graphics_pipeline_library and wondered if it is possible to disable this extension in AMDVLK in order to be able to get a "before and after"-ish comparison.

This is quite easy to do in RADV (RADV_DEBUG=nogpl), but I haven't been able to figure out how to do this in AMDVLK (/AMDGPU-Pro Vulkan).

You could use the runtime setting EnableGraphicsPipelineLibraries to enable/disable the extension.

Thanks for making me aware of this. This option definitely disables GPL.

Is there a complete list of supported runtime options I can look up? The list in this repo is very incomplete.

You could check below files for a complete list:

.../xgl/icd/settings/settings_xgl.json (API layer settings)
.../pal/src/core/settings_core.json (PAL hardware-independent settings)
.../pal/src/core/hw/gfxip/gfx9/settings_gfx9.json (PAL GFX9+ settings)

Will do, thanks a lot!
