VK_KHR_maintenance9(3) Manual Page

Support VkDevice with no queues. These can be used as effectively an offline compiler to prepopulate pipeline caches, without expensive queue creation or internal memory allocations.

Allow vkCmdSetEvent2 to not provide a dependency, providing vkCmdSetEvent-style usage using enums from VK_KHR_synchronization2

Add a VkQueryPoolCreateFlagBits::VK_QUERY_POOL_CREATE_RESET_BIT_KHR flag to create a query pool with all queries initialized to the reset state.

Allow any integer bit width for specific bit-wise operations.

Add a property to enable sparse support with VK_EXT_image_2d_view_of_3d.

Add a property to indicate the implementation will return (0,0,0,0) or (0,0,0,1) to vertex shaders that read unassigned attributes.

The effects of image memory barriers and image layout transitions on 3D images created with VK_IMAGE_CREATE_2D_ARRAY_COMPATIBLE_BIT are scoped to the slices specified by the user-provided VkImageSubresourceRange.

Queue family ownership transfers are no longer required for buffers and linear images, and a new physical device queue family property is exposed to indicate whether queue family ownership transfers are required for optimal images.
