zChange log for June 26, 2026 Vulkan 1.4.355 spec update:

Github Issues

  * Switch to dual Apache 2.0 OR MIT license for generated headers (public
    Vulkan-Headers issue 605).
  * Mark superseded VK_KHR_surface commands as legacy (public PR 2763).
  * Fix two typos in image view usage description (public PR 2765).

Internal Issues

  * Add standalone SPIR-V VU constraining OpUndef (internal issue 4424).
  * Update common draw VU 09116 to require all / no components to be in
    write mask for the 999E5 format (internal issue 4758).
  * Require heap data mappings to UBOs to be aligned in common draw dispatch
    VU 11441 (internal issues 4817, 4859).
  * Remove `chunked` Makefile target and related infrastructure, replacing
    the target rule with an error message pointing to the equivalent chunked
    presentation of the specification on the Vulkan docs site (internal
    issue 4872).
  * Update VkRenderingInfo VUs to explicitly say when resolveImageView is
    VK_NULL_HANDLE (internal issue 4877).
  * Combine common draw dynamic state VUs for
    VK_ANDROID_external_format_resolve (internal MR 7510).
  * Refactor the various places subgroup size control is discussed into the
    new <<shaders-varying-subgroup-size, Varying Subgroup Size>>,
    <<shaders-full-subgroups, Full Subgroups>>, and
    <<shaders-required-subgroup-size, Required Subgroup Size>> sections
    (internal MR 8277).
  * Add an `alias` attribute to XML `member` tags to track feature flags
    which are shared between extension and core features (internal MR 8360).
  * Clarify that if vkSetSwapchainPresentTimingQueueSizeEXT is never called,
    vkQueuePresentKHR with present timing queries will also return
    VK_ERROR_PRESENT_TIMING_QUEUE_FULL_EXT (internal MR 8337).
  * Add support for new XML tags introduced by VK_KHR_extended_flags to
    VulkanObject scripts (internal MR 8356).
  * Add VkDescriptorSetAndBindingMappingEXT VUs to validate
    samplerPushOffset alignment / limits (internal MR 8358).
  * Add VkGpaSessionCreateInfoAMD VU to require secondaryCopySource GPA
    session to have begun and ended (internal MR 8362).
  * Update description of VkPhysicalDeviceDataGraphOperationSupportARM XML
    to remove nonexistent sType / pNext members (internal MR 8367).
  * Reword the NOTE on vkGetPhysicalDeviceDescriptorSizeEXT for clarity
    (internal MR 8370).
