Detailed Description

Implementation of the PhysicalMemoryManager for common mips.

Warning: The implementation of this module has been seriously hacked together. It needs changing, currently it doesn't even support freeing of pages! The common mips implementation of the PhysicalMemoryManager

The copy-constructor

bool MipsCommonPhysicalMemoryManager::allocateRegion	(	MemoryRegion &	Region,
		size_t	cPages,
		size_t	pageConstraints,
		size_t	Flags,
		physical_uintptr_t	start = `-1`
	)

virtual

Allocate a memory-region with specific constraints the pages need to fullfill.

Parameters

[in]	Region	reference to the MemoryRegion object
[in]	cPages	the number of pages to allocate for the MemoryRegion object
[in]	pageConstraints	the constraints the pages have to fullfill
[in]	Flags	flags from the VirtualAddressSpace class namespace
[in]	start	the physical address of the beginning of the region (optional)
