Description

This extension is intended to convey throttle hints to the device, but does not specify the throttling behavior or any minimum guarantees. This extension is intended to communicate information from layered API implementations such as ANGLE to internal proprietary system schedulers.

It has no behavioral implications beyond enabling more intelligent behavior from the system scheduler.

Application developers should avoid using this extension. It is documented solely for the benefit of tools and layer developers, who may need to manipulate pNext chains that include these structures.

There is currently no specification language written for this extension. The links to APIs defined by the extension are to stubs that only include generated content such as API declarations and implicit valid usage statements.

This extension is only intended for use in specific embedded environments with known implementation details, and is therefore undocumented.

New Enums

• ThrottleHintTypeSEC

New Enum Constants

• SEC_THROTTLE_HINT_EXTENSION_NAME

• SEC_THROTTLE_HINT_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_THROTTLE_HINT_FEATURES_SEC

  • STRUCTURE_TYPE_THROTTLE_HINT_SUBMIT_INFO_SEC

Stub API References

There is currently no specification language written for this type. This section acts only as placeholder and to avoid dead links in the specification and reference pages.

// Provided by VK_SEC_throttle_hint
typedef struct VkPhysicalDeviceThrottleHintFeaturesSEC {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           throttleHint;
} VkPhysicalDeviceThrottleHintFeaturesSEC;

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_THROTTLE_HINT_FEATURES_SEC

Structure Chaining

Extends the structures

• DeviceCreateInfo

• PhysicalDeviceFeatures2

There is currently no specification language written for this type. This section acts only as placeholder and to avoid dead links in the specification and reference pages.

// Provided by VK_SEC_throttle_hint
typedef struct VkThrottleHintSubmitInfoSEC {
    VkStructureType          sType;
    const void*              pNext;
    VkThrottleHintTypeSEC    throttleHint;
} VkThrottleHintSubmitInfoSEC;

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_THROTTLE_HINT_SUBMIT_INFO_SEC

• throttleHint must be a valid ThrottleHintTypeSEC value

Structure Chaining

Extends the structure

• SubmitInfo
