layers: Distinguish never-bound from un-bound memory cases Fixes #964 Added special MEMORY_UNBOUND handle (0xF..FE) that indicates that memory bound to an object has been freed. When attempting to bind memory or checking for bound memory, distinguish the never-bound case from the memory un-bound case. For sparse binding case allow for memory to be re-bound. Update tests to account for new error messages. There's a sliver of exposure here if an actual memory handle is MEMORY_UNBOUND. We could remove that exposure by never having unique_objects return MEMORY_UNBOUND as a handle. I believe the exposure is small enough that we don't need to do that, but am open to other opinions.
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.
