* Memory Descriptor
|
|
*
|
|
* A memory descriptor provides information about a block of memory.
|
|
* Typically, each page of memory that the VMM uses will have a memory
|
|
* descriptor associated with it. The VMM will use this information to create
|
|
* its resources, as well as generate page tables as needed.
|
|
*
|
|
* @var memory_descriptor::phys
|
|
* the starting physical address of the block of memory
|
|
* @var memory_descriptor::virt
|
|
* the starting virtual address of the block of memory
|
|
* @var memory_descriptor::type
|
|
* the type of memory block. This is likely architecture specific as
|
|
* this holds information about access rights, etc...
