QuoteChange log for September 29, 2022 Vulkan 1.3.230 spec update:
Public Issues:
* Add common valid usage statements for bind buffer and bind image
commands to prevent rebinding resources after slink:vkFreeMemory (public
issue 1937).
Internal Issues:
* Add common valid usage statements for drawing commands to prevent
binding an input attachment descriptor with an image view that is not in
the framebuffer (internal issue 3223).
* Fix references to nonexistent 'fragmentShadingRate' feature (internal
issue 3235).
* Add valid usage statement to flink:vkCmdCopyQueryPoolResults disallowing
usage on active queries (internal issue 3236).
* Update structure layouts in `video.xml` for the provisional video
extensions to address alignment issues (internal issue 3242).
* Clarify that slink:VkGraphicsPipelineLibraryCreateInfoEXT::pname:flags
excludes linked libraries (internal merge request 5447).
* Change the type of slink:VkVideoReferenceSlotInfoKHR::pname:slotIndex to
`int32_t` in the provisional video extensions (internal merge request
5452).
New Extensions:
* apiext:VK_EXT_device_address_binding_report
* apiext:VK_EXT_device_fault
* apiext:VK_EXT_extended_dynamic_state3
* apiext:VK_EXT_pipeline_protected_access
* apiext:VK_NV_optical_flow
* apiext:VK_NV_present_barrier
QuoteThis extension enables applications to track the binding of regions of the GPU virtual address space, and to associate those regions with Vulkan objects. This extension is primarily intended to aid in crash postmortem, where applications may wish to map a faulting GPU address to a Vulkan object.
For example, a page fault triggered by accessing an address located within a region of the GPU virtual address space that was previously reported as bound and then unbound may indicate a use-after-free error. Similarly, faults generated by accessing virtual addresses outside the limits of a bound region of GPU virtual address space may indicate indexing beyond the bounds of a resource.
QuoteDevice loss can be triggered by a variety of issues, including invalid API usage, implementation errors, or hardware failures.
This extension introduces a new command: flink:vkGetDeviceFaultInfoEXT, which may be called subsequent to a ename: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.
QuoteThis extension adds almost all of the remaining pipeline state as dynamic state to help applications further reduce the number of monolithic pipelines they need to create and bind.
QuoteThis extension allows protected memory access to be specified per pipeline as opposed to per device. Through the usage of this extension, any performance penalty paid due to access to protected memory will be limited to the specific pipelines that make such accesses.
QuoteOptical flow are fundamental algorithms in computer vision (CV) area. This extension allows applications to estimate 2D displacement of pixels between two frames.
QuoteThis extension adds support for synchronizing corresponding presentation requests across multiple swapchains using the present barrier.
