Enum
VkSubgroupFeatureFlagBits
Bitmask describing what group operations are supported with subgroup scope
Bits which can be set in
VkPhysicalDeviceSubgroupProperties::supportedOperations
to specify supported group operations with
subgroup scope are:
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,
} VkSubgroupFeatureFlagBits;
