WorkgroupSize(3)

Name

WorkgroupSize - Size of a workgroup

Description

WorkgroupSize

SPIR-V 1.6 deprecated WorkgroupSize in favor of using the LocalSizeId Execution Mode instead. Support for LocalSizeId was added with VK_KHR_maintenance4 and promoted to core in Version 1.3.

Decorating an object with the WorkgroupSize built-in decoration will make that object contain the dimensions of a local workgroup. If an object is decorated with the WorkgroupSize decoration, this takes precedence over any LocalSize or LocalSizeId execution mode.

Valid Usage

  • VUID-WorkgroupSize-WorkgroupSize-04425
    The WorkgroupSize decoration must be used only within the GLCompute, MeshEXT, TaskEXT, MeshNV, or TaskNV Execution Model

  • VUID-WorkgroupSize-WorkgroupSize-04426
    The variable decorated with WorkgroupSize must be a specialization constant or a constant

  • VUID-WorkgroupSize-WorkgroupSize-04427
    The variable decorated with WorkgroupSize must be declared as a three-component vector of 32-bit integer values

  • VUID-WorkgroupSize-TileShadingRateQCOM-10635
    If the TileShadingRateQCOM Execution Mode is used, variables decorated withWorkgroupSize must be declared using the Input Storage Class
