VkPhysicalDeviceMaintenance7PropertiesKHR

The VkPhysicalDeviceMaintenance7PropertiesKHR structure is defined as:

typedef struct VkPhysicalDeviceMaintenance7PropertiesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 robustFragmentShadingRateAttachmentAccess;
    VkBool32 separateDepthStencilAttachmentAccess;
    uint32_t maxDescriptorSetTotalUniformBuffersDynamic;
    uint32_t maxDescriptorSetTotalStorageBuffersDynamic;
    uint32_t maxDescriptorSetTotalBuffersDynamic;
    uint32_t maxDescriptorSetUpdateAfterBindTotalUniformBuffersDynamic;
    uint32_t maxDescriptorSetUpdateAfterBindTotalStorageBuffersDynamic;
    uint32_t maxDescriptorSetUpdateAfterBindTotalBuffersDynamic;
} VkPhysicalDeviceMaintenance7PropertiesKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• robustFragmentShadingRateAttachmentAccess indicates whether the scaled size of a fragment shading rate attachment can be less than the size of the render area. If robustFragmentShadingRateAttachmentAccess is VK_FALSE, the size of the attachment multiplied by the texel size must be greater than or equal to the size of the render area. If it is VK_TRUE and the fragment shading rate attachment was created with VkImageSubresourceRange::baseMipLevel equal to 0, the scaled size can be smaller than the render area, and shading rates for missing texels are defined by texel replacement for invalid texels.
• separateDepthStencilAttachmentAccess indicates support for writing to one aspect of a depth/stencil attachment without performing read-modify-write operations on the other aspect. If this property is VK_TRUE, writes to one aspect must not result in read-modify-write operations on the other aspect. If VK_FALSE, writes to one aspect may result in writes to the other aspect as defined by render pass load operations, render pass store operations and render pass resolve operations.
• maxDescriptorSetTotalUniformBuffersDynamic is the maximum total count of dynamic uniform buffers that can be included in a pipeline layout. Descriptors with a type of VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC count against this limit. Only descriptors in descriptor set layouts created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit. See Dynamic Uniform Buffer.
• maxDescriptorSetTotalStorageBuffersDynamic is the maximum total count of dynamic storage buffers that can be included in a pipeline layout. Descriptors with a type of VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC count against this limit. Only descriptors in descriptor set layouts created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit. See Dynamic Storage Buffer.
• maxDescriptorSetTotalBuffersDynamic is the maximum total count of dynamic uniform buffers and storage buffers that can be included in a pipeline layout. Descriptors with a type of VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC or VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC count against this limit. Only descriptors in descriptor set layouts created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit.
• maxDescriptorSetUpdateAfterBindTotalUniformBuffersDynamic is similar to maxDescriptorSetTotalUniformBuffersDynamic but counts descriptors from descriptor sets created with or without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set.
• maxDescriptorSetUpdateAfterBindTotalStorageBuffersDynamic is similar to maxDescriptorSetTotalStorageBuffersDynamic but counts descriptors from descriptor sets created with or without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set.
• maxDescriptorSetUpdateAfterBindTotalBuffersDynamic is similar to maxDescriptorSetTotalBuffersDynamic but counts descriptors from descriptor sets created with or without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set. While an application can allocate dynamic storage buffer descriptors from a pool created with the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT, bindings for these descriptors must not be present in any descriptor set layout that includes bindings created with VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT.

If the VkPhysicalDeviceMaintenance7PropertiesKHR structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
