Description

This extension adds more expressive alignment requirements for uniform and storage texel buffers. Some implementations have single texel alignment requirements that cannot be expressed via PhysicalDeviceLimits::minTexelBufferOffsetAlignment.

New Structures

Extending PhysicalDeviceFeatures2, DeviceCreateInfo:
- PhysicalDeviceTexelBufferAlignmentFeaturesEXT

Extending PhysicalDeviceProperties2:
- PhysicalDeviceTexelBufferAlignmentPropertiesEXT

New Enum Constants

EXT_TEXEL_BUFFER_ALIGNMENT_EXTENSION_NAME

VkPhysicalDeviceTexelBufferAlignmentFeaturesEXT - Structure describing the texel buffer alignment features that can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceTexelBufferAlignmentFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceTexelBufferAlignmentFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

PhysicalDeviceTexelBufferAlignmentFeaturesEXT
Fields texelBufferAlignment :: Bool `texelBufferAlignment` indicates whether the implementation uses more specific alignment requirements advertised in `PhysicalDeviceTexelBufferAlignmentPropertiesEXT` rather than `PhysicalDeviceLimits`::`minTexelBufferOffsetAlignment`.

VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT - Structure describing the texel buffer alignment requirements supported by an implementation

Description

If the PhysicalDeviceTexelBufferAlignmentPropertiesEXT structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

If the single texel alignment property is FALSE, then the buffer view’s offset must be aligned to the corresponding byte alignment value. If the single texel alignment property is 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 BufferViewCreateInfo::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 PhysicalDeviceLimits::minTexelBufferOffsetAlignment, for any format that supports use as a texel buffer.

Valid Usage (Implicit)

storageTexelBufferOffsetAlignmentBytes :: DeviceSize
storageTexelBufferOffsetAlignmentBytes is a byte alignment that is sufficient for a storage texel buffer of any format.
storageTexelBufferOffsetSingleTexelAlignment :: Bool
storageTexelBufferOffsetSingleTexelAlignment indicates whether single texel alignment is sufficient for a storage texel buffer of any format.
uniformTexelBufferOffsetAlignmentBytes :: DeviceSize
uniformTexelBufferOffsetAlignmentBytes is a byte alignment that is sufficient for a uniform texel buffer of any format.
uniformTexelBufferOffsetSingleTexelAlignment :: Bool
uniformTexelBufferOffsetSingleTexelAlignment indicates whether single texel alignment is sufficient for a uniform texel buffer of any format.
