IOKit mapping constructor.
- Parameters
-
| iokit_memory_descriptor | IOMemoryDescriptor to be mapped into the kernel address space |
| offset | offset into memory descriptor to create mapping |

kernel map free
Checks if kernel mapping already exists and
does not call unmap(): IOMemoryMap instances will unmap themselves upon free, ie. when the last client with a reference calls release. unmap() forces the IOMemoryMap to destroy the mapping it represents, regardless of the number of clients. releases the map object.

IOKit kernel map initializer.
map<kernel> maps an IOMemoryDescriptor (typically cast of a dxd::memory or buffer class) into the kernel address space.
https://developer.apple.com/library/content/qa/qa1197/_index.html
Allows re-initialization.
Checks buffer object,
maps the buffer into the kernel (will fail if offset is given)
and obtains a kernel virtual address (apply offset here instead).
- Parameters
-
| iokit_memory_descriptor | IOMemoryDescriptor to be mapped into the kernel address space |
