See VkPhysicalDeviceVulkan12Features manual page.

Fields

sampler_mirror_clamp_to_edge: bool

Indicates whether the implementation supports the VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE sampler address mode.

If this feature is not enabled, the VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE sampler address mode must not be used.

draw_indirect_count: bool

Indicates whether the implementation supports the vkCmdDrawIndirectCount and vkCmdDrawIndexedIndirectCount functions.

If this feature is not enabled, these functions must not be used.

storage_buffer8_bit_access: bool

Indicates whether objects in the StorageBuffer, ShaderRecordBufferKHR, or PhysicalStorageBuffer storage class with the Block decoration can have 8-bit integer members.

If this feature is not enabled, 8-bit integer members must not be used in such objects. This also indicates whether shader modules can declare the StorageBuffer8BitAccess capability.

uniform_and_storage_buffer8_bit_access: bool

Indicates whether objects in the Uniform storage class with the Block decoration can have 8-bit integer members.

If this feature is not enabled, 8-bit integer members must not be used in such objects. This also indicates whether shader modules can declare the UniformAndStorageBuffer8BitAccess capability.

Indicates whether objects in the PushConstant storage class can have 8-bit integer members.

If this feature is not enabled, 8-bit integer members must not be used in such objects. This also indicates whether shader modules can declare the StoragePushConstant8 capability.

shader_float16: bool

Indicates whether 16-bit floats (halfs) are supported in shader code.

This also indicates whether shader modules can declare the Float16 capability. However, this only enables a subset of the storage classes that SPIR-V allows for the Float16 SPIR-V capability: Declaring and using 16-bit floats in the Private, Workgroup (for non-Block variables), and Function storage classes is enabled, while declaring them in the interface storage classes (e.g., UniformConstant, Uniform, StorageBuffer, Input, Output, and PushConstant) is not enabled.

shader_int8: bool

Indicates whether 8-bit integers (signed and unsigned) are supported in shader code.

This also indicates whether shader modules can declare the Int8 capability. However, this only enables a subset of the storage classes that SPIR-V allows for the Int8 SPIR-V capability: Declaring and using 8-bit integers in the Private, Workgroup (for non-Block variables), and Function storage classes is enabled, while declaring them in the interface storage classes (e.g., UniformConstant, Uniform, StorageBuffer, Input, Output, and PushConstant) is not enabled.
