IOBufferMemoryDescriptor
IOBufferMemory is a term used to describe a memory region allocated to hold data being transferred through input/output channels. It serves as a buffer between producers and consumers of data, smoothing speed mismatches and enabling efficient data movement between devices, peripherals, and software layers.
In many systems, IOBufferMemory can be allocated from pageable or pinned memory. For devices that perform direct
Lifecycle and synchronization: buffers are allocated, filled by a producer, handed off to a consumer or device,
