C Specification

Bits which can be set in VkPhysicalDeviceSubgroupProperties::supportedOperations and VkPhysicalDeviceVulkan11Properties::subgroupSupportedOperations to specify supported group operations with subgroup scope are:

// Provided by VK_VERSION_1_1
typedef enum VkSubgroupFeatureFlagBits {
    VK_SUBGROUP_FEATURE_BASIC_BIT = 0x00000001,
    VK_SUBGROUP_FEATURE_VOTE_BIT = 0x00000002,
    VK_SUBGROUP_FEATURE_ARITHMETIC_BIT = 0x00000004,
    VK_SUBGROUP_FEATURE_BALLOT_BIT = 0x00000008,
    VK_SUBGROUP_FEATURE_SHUFFLE_BIT = 0x00000010,
    VK_SUBGROUP_FEATURE_SHUFFLE_RELATIVE_BIT = 0x00000020,
    VK_SUBGROUP_FEATURE_CLUSTERED_BIT = 0x00000040,
    VK_SUBGROUP_FEATURE_QUAD_BIT = 0x00000080,
  // Provided by VK_NV_shader_subgroup_partitioned
    VK_SUBGROUP_FEATURE_PARTITIONED_BIT_NV = 0x00000100,
  // Provided by VK_KHR_shader_subgroup_rotate
    VK_SUBGROUP_FEATURE_ROTATE_BIT_KHR = 0x00000200,
  // Provided by VK_KHR_shader_subgroup_rotate
    VK_SUBGROUP_FEATURE_ROTATE_CLUSTERED_BIT_KHR = 0x00000400,
} VkSubgroupFeatureFlagBits;

Description

  • VK_SUBGROUP_FEATURE_BASIC_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniform capability.

  • VK_SUBGROUP_FEATURE_VOTE_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniformVote capability.

  • VK_SUBGROUP_FEATURE_ARITHMETIC_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniformArithmetic capability.

  • VK_SUBGROUP_FEATURE_BALLOT_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniformBallot capability.

  • VK_SUBGROUP_FEATURE_SHUFFLE_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniformShuffle capability.

  • VK_SUBGROUP_FEATURE_SHUFFLE_RELATIVE_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniformShuffleRelative capability.

  • VK_SUBGROUP_FEATURE_CLUSTERED_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniformClustered capability.

  • VK_SUBGROUP_FEATURE_QUAD_BIT specifies the device will accept SPIR-V shader modules containing the GroupNonUniformQuad capability.

  • VK_SUBGROUP_FEATURE_PARTITIONED_BIT_NV specifies the device will accept SPIR-V shader modules containing the GroupNonUniformPartitionedNV capability.

  • VK_SUBGROUP_FEATURE_ROTATE_BIT_KHR specifies the device will accept SPIR-V shader modules containing the GroupNonUniformRotateKHR capability.

  • VK_SUBGROUP_FEATURE_ROTATE_CLUSTERED_BIT_KHR specifies the device will accept SPIR-V shader modules that use the ClusterSize operand to OpGroupNonUniformRotateKHR.
