VkTensorMemoryBarrierARM

The VkTensorMemoryBarrierARM structure is defined as:

typedef struct VkTensorMemoryBarrierARM {
    VkStructureType sType;
    const void* pNext;
    VkPipelineStageFlags2 srcStageMask;
    VkAccessFlags2 srcAccessMask;
    VkPipelineStageFlags2 dstStageMask;
    VkAccessFlags2 dstAccessMask;
    uint32_t srcQueueFamilyIndex;
    uint32_t dstQueueFamilyIndex;
    VkTensorARM tensor;
} VkTensorMemoryBarrierARM;

pub struct TensorMemoryBarrierARM {
    s_type: vk::StructureType,
    p_next: *const c_void,
    src_stage_mask: vk::PipelineStageFlags2,
    src_access_mask: vk::AccessFlags2,
    dst_stage_mask: vk::PipelineStageFlags2,
    dst_access_mask: vk::AccessFlags2,
    src_queue_family_index: u32,
    dst_queue_family_index: u32,
    tensor: vk::TensorARM,
}

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• srcStageMask is a VkPipelineStageFlags2 mask of pipeline stages to be included in the first synchronization scope.
• srcAccessMask is a VkAccessFlags2 mask of access flags to be included in the first access scope.
• dstStageMask is a VkPipelineStageFlags2 mask of pipeline stages to be included in the second synchronization scope.
• dstAccessMask is a VkAccessFlags2 mask of access flags to be included in the second access scope.
• srcQueueFamilyIndex is the source queue family for a queue family ownership transfer.
• dstQueueFamilyIndex is the destination queue family for a queue family ownership transfer.
• tensor is a handle to the tensor whose backing memory is affected by the barrier.

The first synchronization scope and access scope described by this structure include only operations and memory accesses specified by srcStageMask and srcAccessMask.

The second synchronization scope and access scope described by this structure include only operations and memory accesses specified by dstStageMask and dstAccessMask.

Both access scopes are limited to only memory accesses to tensor.

If tensor was created with VK_SHARING_MODE_EXCLUSIVE, and srcQueueFamilyIndex is not equal to dstQueueFamilyIndex, this memory barrier defines a queue family transfer operation. When executed on a queue in the family identified by srcQueueFamilyIndex, this barrier defines a queue family release operation for the specified tensor, and the second synchronization and access scopes do not synchronize operations on that queue. When executed on a queue in the family identified by dstQueueFamilyIndex, this barrier defines a queue family acquire operation for the specified tensor, and the first synchronization and access scopes do not synchronize operations on that queue.

A queue family transfer operation is also defined if the values are not equal, and either is one of the special queue family values reserved for external memory ownership transfers, as described in Queue Family Ownership Transfer. A queue family release operation is defined when dstQueueFamilyIndex is one of those values, and a queue family acquire operation is defined when srcQueueFamilyIndex is one of those values.
