Description

This extension adds support for additional 1-, 2- and 4-component formats with 10, 12, or 14 bits of components in 16-bit containers.

New Structures

Extending PhysicalDeviceFeatures2, DeviceCreateInfo:
- PhysicalDeviceFormatPackFeaturesARM

New Enum Constants

ARM_FORMAT_PACK_EXTENSION_NAME

What do we call this extension?

RESOLVED

Many existing extension have the format in the name, but in this case we want to expose multiple formats.

We will describe this set of formats as a “pack”.

Compatibility classes

RESOLVED: Should these additional formats be in the same compatibility class as any other formats? For single-plane formats, we put formats with the same number of bits (but different types) in the same class. Each multi-plane or subsampled format gets its own compatibility class. This is consistent with how existing formats are handled.

Format feature requirements

RESOLVED: The format feature queries could be used to determine what is supported on any given implementation, but it may be useful to establish a baseline requirement in the specification. For that purpose, we require a set of format features - sufficient to enable texture operations - to be supported for the added unsigned integer single-plane formats. Other formats and format features are optional.

VkPhysicalDeviceFormatPackFeaturesARM - Structure describing whether the additional formats feature is supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceFormatPackFeaturesARM 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. If the application wishes to use a Device with any features described by PhysicalDeviceFormatPackFeaturesARM, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.

Valid Usage (Implicit)

formatPack :: Bool
formatPack indicates that the implementation must support using a Format of FORMAT_R10X6_UINT_PACK16_ARM, FORMAT_R10X6G10X6_UINT_2PACK16_ARM, FORMAT_R10X6G10X6B10X6A10X6_UINT_4PACK16_ARM, FORMAT_R12X4_UINT_PACK16_ARM, FORMAT_R12X4G12X4_UINT_2PACK16_ARM, FORMAT_R12X4G12X4B12X4A12X4_UINT_4PACK16_ARM, FORMAT_R14X2_UINT_PACK16_ARM, FORMAT_R14X2G14X2_UINT_2PACK16_ARM, and FORMAT_R14X2G14X2B14X2A14X2_UINT_4PACK16_ARM, with at least the following FormatFeatureFlagBits:
