layers: Tuning MemTracker Reverse sense of fenceMap using VkFence instead of fenceID as key. This eliminates iterating over all of fenceMap. Stop creating internal fences and let vkQueueSubmit pass NULL fence. Track lastSubmittedFence and lastSubmittedQueue in command buffer info. Use unordered_map instead of map for better performance. Reuse iterator returned by map find whenever available. It is faster than repeating a find operation with "[]" notation. Remove map entries at time of VkDestroy instead of other calls such as Wait.
Version 0.8, 04 Feb 2015
This project provides open source tools for VK Developers.
VK is an Explicit API, enabling direct control over how GPUs actually work. No validation, shader recompilation, memory management or synchronization is done inside an VK driver. Applications have full control and responsibility. Any errors in how VK is used are likely to result in a crash. This project provides layered utility libraries to ease development and help guide developers to proven safe patterns.
New with VK in an extensible layered architecture that enables significant innovation in tools:
The components here are being shared with the Khronos community to provide insights into the specification as we approach an alpha header, and to assists those doing demos for GDC.
The following components are available:
VK Library and header files, which include:
Core Validation Layers
BUILD.md includes directions for building all the components, running the validation tests and running the demo applications.
Information on how to enable the various Debug and Validation layers is in layers/README.md.
This version of the components are written based on the following preliminary specs and proposals:
This work is intended to be released as open source under a BSD-style license once the VK specification is public. Until that time, this work is covered by the Khronos NDA governing the details of the VK API.
While this project is being developed by LunarG, Inc; there are many other companies and individuals making this possible: Valve Software, funding project development; Intel Corporation, providing full hardware specifications and valuable technical feedback; AMD, providing VK spec editor contributions; ARM, contributing a Chairman for this working group within Khronos; Nvidia, providing an initial co-editor for the spec; Qualcomm for picking up the co-editor's chair; and Khronos, for providing hosting within GitHub.
