vkCmdSetDispatchParametersARM - Set parameters that affect dispatch commands

Description

Parameters set using cmdSetDispatchParametersARM affect the following dispatch commands:

• cmdDispatch

• cmdDispatchBase

• cmdDispatchIndirect

Valid Usage

• PhysicalDeviceSchedulingControlsPropertiesARM::schedulingControlsFlags must contain PHYSICAL_DEVICE_SCHEDULING_CONTROLS_DISPATCH_PARAMETERS_ARM

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• pDispatchParameters must be a valid pointer to a valid DispatchParametersARM structure

• commandBuffer must be in the recording state

• The CommandPool that commandBuffer was allocated from must support QUEUE_COMPUTE_BIT operations

• This command must only be called outside of a render pass instance

• This command must only be called outside of a video coding scope

Host Synchronization

• Host access to commandBuffer must be externally synchronized

• Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

VkDeviceQueueShaderCoreControlCreateInfoARM - Control the number of shader cores used by queues

Description

Queues created without specifying DeviceQueueShaderCoreControlCreateInfoARM will default to using all the shader cores available.

VkPhysicalDeviceSchedulingControlsFeaturesARM - Structure describing scheduling controls features that can be supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDeviceSchedulingControlsFeaturesARM structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceSchedulingControlsFeaturesARM, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.

VkPhysicalDeviceSchedulingControlsPropertiesARM - Structure containing scheduling control properties of a physical device

Members

• schedulingControlsFlags specifies the specific scheduling controls that a physical device supports.

Description

If the PhysicalDeviceSchedulingControlsPropertiesARM structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

VkPhysicalDeviceSchedulingControlsDispatchParametersPropertiesARM - Structure containing scheduling control dispatch parameters properties of a physical device

Members

• schedulingControlsMaxWarpsCount specifies the maximum number of warps that a shader core can run concurrently.

• schedulingControlsMaxQueuedWorkgroupBatchesCount specifies the maximum number of workgroup batches that a shader core can queue.

• schedulingControlsMaxWorkGroupBatchSize specifies the maximum size of workgroup batches that can be requested using DispatchParametersARM::workGroupBatchSize.

Description

If the PhysicalDeviceSchedulingControlsDispatchParametersPropertiesARM structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

If PhysicalDeviceSchedulingControlsPropertiesARM::schedulingControlsFlags does not contain PHYSICAL_DEVICE_SCHEDULING_CONTROLS_DISPATCH_PARAMETERS_ARM then schedulingControlsMaxWarpCount and schedulingControlsMaxQueuedBatchesCount are undefined.

VkPhysicalDeviceSchedulingControlsFlagBitsARM - Bitmask specifying scheduling controls supported by a physical device

Description

• PHYSICAL_DEVICE_SCHEDULING_CONTROLS_SHADER_CORE_COUNT_ARM specifies that a DeviceQueueShaderCoreControlCreateInfoARM structure may be included in the pNext chain of a DeviceQueueCreateInfo or DeviceCreateInfo structure.

• PHYSICAL_DEVICE_SCHEDULING_CONTROLS_DISPATCH_PARAMETERS_ARM specifies that a cmdSetDispatchParametersARM command may be recorded in a command buffer and that properties returned in PhysicalDeviceSchedulingControlsDispatchParametersPropertiesARM are valid.
