Vulkan.Core10.Enums.PipelineShaderStageCreateFlagBits

VkPipelineShaderStageCreateFlagBits - Bitmask controlling how a pipeline shader stage is created

Description

• PIPELINE_SHADER_STAGE_CREATE_ALLOW_VARYING_SUBGROUP_SIZE_BIT specifies that the SubgroupSize may vary in the shader stage.

• PIPELINE_SHADER_STAGE_CREATE_REQUIRE_FULL_SUBGROUPS_BIT specifies that the subgroup sizes must be launched with all invocations active in the task, mesh, or compute stage.

If PIPELINE_SHADER_STAGE_CREATE_ALLOW_VARYING_SUBGROUP_SIZE_BIT_EXT and PIPELINE_SHADER_STAGE_CREATE_REQUIRE_FULL_SUBGROUPS_BIT_EXT are specified and minSubgroupSize does not equal maxSubgroupSize and no required subgroup size is specified, then the only way to guarantee that the 'X' dimension of the local workgroup size is a multiple of SubgroupSize is to make it a multiple of maxSubgroupSize. Under these conditions, you are guaranteed full subgroups but not any particular subgroup size.
