C Specification
The VkTensorMemoryBarrierARM structure is defined as:
// Provided by VK_ARM_tensors
typedef struct VkTensorMemoryBarrierARM {
    VkStructureType          sType;
    const void*              pNext;
    VkPipelineStageFlags2    srcStageMask;

    VkAccessFlags2           dstAccessMask;
    uint32_t                 srcQueueFamilyIndex;
    uint32_t                 dstQueueFamilyIndex;

-

tensoris a handle to the tensor whose backing memory is affected by the barrier.
Description
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 https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#synchronization-queue-transfers.
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.
