Providing access to physical memory allocated to a process by selectively mapping pages of the physical memory with virtual memory allocated to the process

A system for providing improved memory access to a process, comprising,

• physical memory;
• a memory manager, the memory manager configured to receive requests from the process, the requests including an allocation request for virtual memory, an allocation request for physical memory, and a request to map virtual memory to physical memory;
• and
• the memory manager including at least one mechanism for determining whether the process is entitled to map the virtual memory to the physical memory, and if so, the memory manager configured to instruct a processor to map the virtual memory to the physical memory.

In a computer system having physical memory and at least one processor, a method for accessing the physical memory, comprising:

• receiving a request from a process for physical memory, and in response, allocating at least one page of physical memory thereto;
• receiving a request from the process for virtual memory capable of being mapped to physical memory, and in response, allocating virtual memory thereto;
• receiving a mapping request from the process to map a range of virtual memory to at least one page of the physical memory, the request including a variable corresponding to the range of virtual memory and a list of each physical page;
• determining whether the process has the range of virtual memory allocated thereto, and if not, failing the mapping request;
• and
• determining whether the process is entitled to access each page of physical memory requested, and if so, mapping a virtual memory location in the range of virtual memory to each page of the physical memory, and if not, failing the request.
