Class EXTPipelineProtectedAccess

org.lwjgl.vulkan.EXTPipelineProtectedAccess

public final class EXTPipelineProtectedAccess
extends Object

This extension allows protected memory access to be specified per pipeline as opposed to per device. Through the usage of this extension, any performance penalty paid due to access to protected memory will be limited to the specific pipelines that make such accesses.

Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4 with the EXT suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
