C Specification

Possible values of the flags member of VkShaderCreateInfoEXT specifying how a shader object is created, are:

// Provided by VK_EXT_shader_object
typedef enum VkShaderCreateFlagBitsEXT {
    VK_SHADER_CREATE_LINK_STAGE_BIT_EXT = 0x00000001,
    VK_SHADER_CREATE_ALLOW_VARYING_SUBGROUP_SIZE_BIT_EXT = 0x00000002,
    VK_SHADER_CREATE_REQUIRE_FULL_SUBGROUPS_BIT_EXT = 0x00000004,
    VK_SHADER_CREATE_NO_TASK_SHADER_BIT_EXT = 0x00000008,
    VK_SHADER_CREATE_DISPATCH_BASE_BIT_EXT = 0x00000010,
    VK_SHADER_CREATE_FRAGMENT_SHADING_RATE_ATTACHMENT_BIT_EXT = 0x00000020,
    VK_SHADER_CREATE_FRAGMENT_DENSITY_MAP_ATTACHMENT_BIT_EXT = 0x00000040,
} VkShaderCreateFlagBitsEXT;

Description

  • VK_SHADER_CREATE_LINK_STAGE_BIT_EXT specifies that this stage is linked to all other stages being created in the same vkCreateShadersEXT call whose VkShaderCreateInfoEXT structures have the VK_SHADER_CREATE_LINK_STAGE_BIT_EXT flag set in flags.

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

  • VK_SHADER_CREATE_REQUIRE_FULL_SUBGROUPS_BIT_EXT specifies that the subgroup sizes must be launched with all invocations active in the compute stage.

  • VK_SHADER_CREATE_NO_TASK_SHADER_BIT_EXT specifies that the mesh shader being created must only be used without a task shader. Otherwise, the mesh shader being created must only be used with a task shader.

  • VK_SHADER_CREATE_DISPATCH_BASE_BIT_EXT specifies that a compute shader can be used with vkCmdDispatchBase with a non-zero base workgroup.

  • VK_SHADER_CREATE_FRAGMENT_SHADING_RATE_ATTACHMENT_BIT_EXT specifies that the fragment shader can be used with a fragment shading rate attachment.

  • VK_SHADER_CREATE_FRAGMENT_DENSITY_MAP_ATTACHMENT_BIT_EXT specifies that the fragment shader can be used with a fragment density map attachment.
