Description
Device loss can be triggered by a variety of issues, including invalid API usage, implementation errors, or hardware failures. This extension introduces two new commands:
vkGetDeviceFaultReportsKHR 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. Additionally this command allows developers to query for additional information on GPU faults which were internally recovered by the implementation.
vkGetDeviceFaultReportsKHR differs from vkGetDeviceFaultInfoEXT in that it can be called at any time, is able to report faults which do not result in VK_ERROR_DEVICE_LOST and allows the caller to wait for such an error to occur.
vkGetDeviceFaultDebugInfoKHR provides a separate interface which must only be called when a device loss has occurred to provide extended GPU vendor specific crash post-mortem information.
