C Specification

The VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT structure is defined as:

typedef struct VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkDeviceSize       storageTexelBufferOffsetAlignmentBytes;
    VkBool32           storageTexelBufferOffsetSingleTexelAlignment;
    VkDeviceSize       uniformTexelBufferOffsetAlignmentBytes;
    VkBool32           uniformTexelBufferOffsetSingleTexelAlignment;
} VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT;

Members

The members of the VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT structure describe the following implementation-dependent limits:

Description

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • storageTexelBufferOffsetAlignmentBytes is a byte alignment that is sufficient for a storage texel buffer of any format.

  • storageTexelBufferOffsetSingleTexelAlignment indicates whether single texel alignment is sufficient for a storage texel buffer of any format.

  • uniformTexelBufferOffsetAlignmentBytes is a byte alignment that is sufficient for a uniform texel buffer of any format.

  • uniformTexelBufferOffsetSingleTexelAlignment indicates whether single texel alignment is sufficient for a uniform texel buffer of any format.

If the VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT structure is included in the pNext chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.

If the single texel alignment property is VK_FALSE, then the buffer view’s offset must be aligned to the corresponding byte alignment value. If the single texel alignment property is VK_TRUE, then the buffer view’s offset must be aligned to the lesser of the corresponding byte alignment value or the size of a single texel, based on VkBufferViewCreateInfo::format. If the size of a single texel is a multiple of three bytes, then the size of a single component of the format is used instead.

These limits must not advertise a larger alignment than the required maximum minimum value of VkPhysicalDeviceLimits::minTexelBufferOffsetAlignment, for any format that supports use as a texel buffer.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_PROPERTIES_EXT
