C Specification
The VkPhysicalDeviceMaintenance7PropertiesKHR structure is defined as:
// Provided by VK_KHR_maintenance7
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;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
robustFragmentShadingRateAttachmentAccessindicates whether the scaled size of a fragment shading rate attachment can be less than the size of the render area. IfrobustFragmentShadingRateAttachmentAccessisVK_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 isVK_TRUEand the fragment shading rate attachment was created with VkImageSubresourceRange::baseMipLevelequal 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. -
separateDepthStencilAttachmentAccessindicates support for writing to one aspect of a depth/stencil attachment without performing read-modify-write operations on the other aspect. If this property isVK_TRUE, writes to one aspect must not result in read-modify-write operations on the other aspect. IfVK_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. -
maxDescriptorSetTotalUniformBuffersDynamicis the maximum total count of dynamic uniform buffers that can be included in a pipeline layout. Descriptors with a type ofVK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMICcount against this limit. Only descriptors in descriptor set layouts created without theVK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BITbit set count against this limit. See https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#descriptorsets-uniformbufferdynamic. -
maxDescriptorSetTotalStorageBuffersDynamicis the maximum total count of dynamic storage buffers that can be included in a pipeline layout. Descriptors with a type ofVK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMICcount against this limit. Only descriptors in descriptor set layouts created without theVK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BITbit set count against this limit. See https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#descriptorsets-storagebufferdynamic. -
maxDescriptorSetTotalBuffersDynamicis the maximum total count of dynamic uniform buffers and storage buffers that can be included in a pipeline layout. Descriptors with a type ofVK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMICorVK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMICcount against this limit. Only descriptors in descriptor set layouts created without theVK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BITbit set count against this limit. -
maxDescriptorSetUpdateAfterBindTotalUniformBuffersDynamicis similar tomaxDescriptorSetTotalUniformBuffersDynamicbut counts descriptors from descriptor sets created with or without theVK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BITbit set. -
maxDescriptorSetUpdateAfterBindTotalStorageBuffersDynamicis similar tomaxDescriptorSetTotalStorageBuffersDynamicbut counts descriptors from descriptor sets created with or without theVK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BITbit set. -
maxDescriptorSetUpdateAfterBindTotalBuffersDynamicis similar tomaxDescriptorSetTotalBuffersDynamicbut counts descriptors from descriptor sets created with or without theVK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BITbit set. While an application can allocate dynamic storage buffer descriptors from a pool created with theVK_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 withVK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT.
Description
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.
