# VkScopeKHR(3) Manual Page

## Name

VkScopeKHR - Specify SPIR-V scope

Loading… please wait.

## C Specification

Possible values for VkScopeKHR include:

    // Provided by VK_KHR_cooperative_matrix
    typedef enum VkScopeKHR {
        VK_SCOPE_DEVICE_KHR = 1,
        VK_SCOPE_WORKGROUP_KHR = 2,
        VK_SCOPE_SUBGROUP_KHR = 3,
        VK_SCOPE_QUEUE_FAMILY_KHR = 5,
      // Provided by VK_NV_cooperative_matrix
        VK_SCOPE_DEVICE_NV = VK_SCOPE_DEVICE_KHR,
      // Provided by VK_NV_cooperative_matrix
        VK_SCOPE_WORKGROUP_NV = VK_SCOPE_WORKGROUP_KHR,
      // Provided by VK_NV_cooperative_matrix
        VK_SCOPE_SUBGROUP_NV = VK_SCOPE_SUBGROUP_KHR,
      // Provided by VK_NV_cooperative_matrix
        VK_SCOPE_QUEUE_FAMILY_NV = VK_SCOPE_QUEUE_FAMILY_KHR,
    } VkScopeKHR;

or the equivalent

    // Provided by VK_NV_cooperative_matrix
    typedef VkScopeKHR VkScopeNV;

## Description

- `VK_SCOPE_DEVICE_KHR` corresponds to SPIR-V `Device` scope.

- `VK_SCOPE_WORKGROUP_KHR` corresponds to SPIR-V `Workgroup` scope.

- `VK_SCOPE_SUBGROUP_KHR` corresponds to SPIR-V `Subgroup` scope.

- `VK_SCOPE_QUEUE_FAMILY_KHR` corresponds to SPIR-V `QueueFamily` scope.

All enum values match the corresponding SPIR-V value.
