Enumeration Type Documentation

enum Memory_class

This enum is used for specifying what sort of memory is required when allocating physical memory pages.
For example, some DMA transfers require their buffers to be below the one megabyte mark. It is assumed that the memory classes are ordered in descending order of preciousness.
Enumeration values:

MEM_CLASS_BELOW_1MB

MEM_CLASS_ABOVE_1MB

MEM_CLASS_ANY
