Class NVShaderSmBuiltins

java.lang.Object

org.lwjgl.vulkan.NVShaderSmBuiltins

public final class NVShaderSmBuiltins
extends java.lang.Object

Description

This extension provides the ability to determine device-specific properties on NVIDIA GPUs. It provides the number of streaming multiprocessors (SMs), the maximum number of warps (subgroups) that can run on an SM, and shader builtins to enable invocations to identify which SM and warp a shader invocation is executing on.

This extension enables support for the SPIR-V ShaderSMBuiltinsNV capability.

These properties and built-ins should typically only be used for debugging purposes.
