Description
If the VkPhysicalDeviceShaderIntegerDotProductPropertiesKHR
structure is included in the pNext
chain of the
VkPhysicalDeviceProperties2 structure passed to
vkGetPhysicalDeviceProperties2, it is filled in with each
corresponding implementation-dependent property.
These are properties of the integer dot product acceleration information of a physical device.
Note
A dot product operation is deemed accelerated if its implementation provides a performance advantage over application-provided code composed from elementary instructions and/or other dot product instructions, either because the implementation uses optimized machine code sequences whose generation from application-provided code cannot be guaranteed or because it uses hardware features that cannot otherwise be targeted from application-provided code. |
