layers: Track valid dynamic scissor and viewport indices with masks CmdSetViewport/CmdSetScissor were broken; they assumed the update replaced all the viewports/scissors; further, the drawtime validation was too aggressive -- nowhere does the spec require the number of valid dynamic viewports/ dynamic scissors to be equal to the number used by the PSO; just that all viewports/scissors used by the PSO must be provided. V2: Add more parens to quiet warnings in android build Signed-off-by: Chris Forbes <chrisforbes@google.com>
This project provides Khronos official ICD loader and validation layers for Vulkan developers on Windows and Linux.
Vulkan is an Explicit API, enabling direct control over how GPUs actually work. No (or very little) validation or error checking is done inside a Vulkan driver. Applications have full control and responsibility. Any errors in how Vulkan is used often result in a crash. This project provides standard validation layers that can be enabled to ease development by helping developers verify their applications correctly use the Vulkan API.
Vulkan supports multiple GPUs and multiple global contexts (VkInstance). The ICD loader is necessary to support multiple GPUs and the VkInstance level Vulkan commands. Additionally, the loader manages inserting Vulkan layer libraries, including validation layers between the application and the ICD.
The following components are available in this repository:
If you intend to contribute, the preferred work flow is for you to develop your contribution in a fork of this repo in your GitHub account and then submit a pull request. Please see the CONTRIBUTING file in this respository for more details
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 Validation layers is in layers/README.md.
Architecture and interface information for the loader is in loader/LoaderAndLayerInterface.md.
