Fields

• robustBufferAccess :: Bool

  robustBufferAccess specifies that accesses to buffers are bounds-checked against the range of the buffer descriptor (as determined by DescriptorBufferInfo::range, BufferViewCreateInfo::range, or the size of the buffer). Out of bounds accesses must not cause application termination, and the effects of shader loads, stores, and atomics must conform to an implementation-dependent behavior as described below.

  • A buffer access is considered to be out of bounds if any of the following are true:

    • The pointer was formed by OpImageTexelPointer and the coordinate is less than zero or greater than or equal to the number of whole elements in the bound range.

    • The pointer was not formed by OpImageTexelPointer and the object pointed to is not wholly contained within the bound range. This includes accesses performed via variable pointers where the buffer descriptor being accessed cannot be statically determined. Uninitialized pointers and pointers equal to OpConstantNull are treated as pointing to a zero-sized object, so all accesses through such pointers are considered to be out of bounds. Buffer accesses through buffer device addresses are not bounds-checked. If the cooperativeMatrixRobustBufferAccess feature is not enabled, then accesses using OpCooperativeMatrixLoadNV and OpCooperativeMatrixStoreNV may not be bounds-checked.

      Note

      If a SPIR-V OpLoad instruction loads a structure and the tail end of the structure is out of bounds, then all members of the structure are considered out of bounds even if the members at the end are not statically used.

    • If robustBufferAccess2 is not enabled and any buffer access is determined to be out of bounds, then any other access of the same type (load, store, or atomic) to the same buffer that accesses an address less than 16 bytes away from the out of bounds address may also be considered out of bounds.
    • If the access is a load that reads from the same memory locations as a prior store in the same shader invocation, with no other intervening accesses to the same memory locations in that shader invocation, then the result of the load may be the value stored by the store instruction, even if the access is out of bounds. If the load is Volatile, then an out of bounds load must return the appropriate out of bounds value.
  • Accesses to descriptors written with a NULL_HANDLE resource or view are not considered to be out of bounds. Instead, each type of descriptor access defines a specific behavior for accesses to a null descriptor.

  • Out-of-bounds buffer loads will return any of the following values:

    • If the access is to a uniform buffer and robustBufferAccess2 is enabled, loads of offsets between the end of the descriptor range and the end of the descriptor range rounded up to a multiple of robustUniformBufferAccessSizeAlignment bytes must return either zero values or the contents of the memory at the offset being loaded. Loads of offsets past the descriptor range rounded up to a multiple of robustUniformBufferAccessSizeAlignment bytes must return zero values.
    • If the access is to a storage buffer and robustBufferAccess2 is enabled, loads of offsets between the end of the descriptor range and the end of the descriptor range rounded up to a multiple of robustStorageBufferAccessSizeAlignment bytes must return either zero values or the contents of the memory at the offset being loaded. Loads of offsets past the descriptor range rounded up to a multiple of robustStorageBufferAccessSizeAlignment bytes must return zero values. Similarly, stores to addresses between the end of the descriptor range and the end of the descriptor range rounded up to a multiple of robustStorageBufferAccessSizeAlignment bytes may be discarded.
    • Non-atomic accesses to storage buffers that are a multiple of 32 bits may be decomposed into 32-bit accesses that are individually bounds-checked.
    • If the access is to an index buffer and robustBufferAccess2 is enabled, zero values must be returned.
    • If the access is to a uniform texel buffer or storage texel buffer and robustBufferAccess2 is enabled, zero values must be returned, and then Conversion to RGBA is applied based on the buffer view’s format.
    • Values from anywhere within the memory range(s) bound to the buffer (possibly including bytes of memory past the end of the buffer, up to the end of the bound range).

    • Zero values, or (0,0,0,x) vectors for vector reads where x is a valid value represented in the type of the vector components and may be any of:

      • 0, 1, or the maximum representable positive integer value, for signed or unsigned integer components
      • 0.0 or 1.0, for floating-point components

  • Out-of-bounds writes may modify values within the memory range(s) bound to the buffer, but must not modify any other memory.

    • If robustBufferAccess2 is enabled, out of bounds writes must not modify any memory.

  • Out-of-bounds atomics may modify values within the memory range(s) bound to the buffer, but must not modify any other memory, and return an undefined value.

    • If robustBufferAccess2 is enabled, out of bounds atomics must not modify any memory, and return an undefined value.

  • If robustBufferAccess2 is disabled, vertex input attributes are considered out of bounds if the offset of the attribute in the bound vertex buffer range plus the size of the attribute is greater than either:

    • vertexBufferRangeSize, if bindingStride == 0; or
    • (vertexBufferRangeSize - (vertexBufferRangeSize % bindingStride))

    where vertexBufferRangeSize is the byte size of the memory range bound to the vertex buffer binding and bindingStride is the byte stride of the corresponding vertex input binding. Further, if any vertex input attribute using a specific vertex input binding is out of bounds, then all vertex input attributes using that vertex input binding for that vertex shader invocation are considered out of bounds.

    • If a vertex input attribute is out of bounds, it will be assigned one of the following values:

      • Values from anywhere within the memory range(s) bound to the buffer, converted according to the format of the attribute.
      • Zero values, format converted according to the format of the attribute.
      • Zero values, or (0,0,0,x) vectors, as described above.

  • If robustBufferAccess2 is enabled, vertex input attributes are considered out of bounds if the offset of the attribute in the bound vertex buffer range plus the size of the attribute is greater than the byte size of the memory range bound to the vertex buffer binding.

    • If a vertex input attribute is out of bounds, the raw data extracted are zero values, and missing G, B, or A components are filled with (0,0,1).
  • If robustBufferAccess is not enabled, applications must not perform out of bounds accesses.
• fullDrawIndexUint32 :: Bool

  fullDrawIndexUint32 specifies the full 32-bit range of indices is supported for indexed draw calls when using a IndexType of INDEX_TYPE_UINT32. maxDrawIndexedIndexValue is the maximum index value that may be used (aside from the primitive restart index, which is always 232-1 when the IndexType is INDEX_TYPE_UINT32).

If this feature is not supported, the implementation supports only boolean occlusion queries. When any samples are passed, boolean queries will return a non-zero result value, otherwise a result value of zero is returned. When this feature is enabled and QUERY_CONTROL_PRECISE_BIT is set, occlusion queries will report the actual number of samples passed.

  • FORMAT_R16G16_UINT
  • FORMAT_R8G8_UINT
  • FORMAT_R16_UINT
  • FORMAT_R8_UINT

  Note

  shaderStorageImageExtendedFormats feature only adds a guarantee of format support, which is specified for the whole physical device. Therefore enabling or disabling the feature via createDevice has no practical effect.

  To query for additional properties, or if the feature is not supported, getPhysicalDeviceFormatProperties and getPhysicalDeviceImageFormatProperties can be used to check for supported properties of individual formats, as usual rules allow.

  FORMAT_R32G32_UINT, FORMAT_R32G32_SINT, and FORMAT_R32G32_SFLOAT from StorageImageExtendedFormats SPIR-V capability, are already covered by core Vulkan mandatory format support.

  Note

  The intent of the viewportBoundsRange limit is to allow a maximum sized viewport to be arbitrarily shifted relative to the output target as long as at least some portion intersects. This would give a bounds limit of [-size + 1, 2 × size - 1] which would allow all possible non-empty-set intersections of the output target and the viewport. Since these numbers are typically powers of two, picking the signed number range using the smallest possible number of bits ends up with the specified range.
