Description

Device loss can be triggered by a variety of issues, including invalid API usage, implementation errors, or hardware failures.

This extension introduces a new command: vkGetDeviceFaultInfoEXT, which may be called subsequent to a VK_ERROR_DEVICE_LOST error code having been returned by the implementation. This command allows developers to query for additional information on GPU faults which may have caused device loss, and to generate binary crash dumps, which may be loaded into external tools for further diagnosis.
