Module kernel::mem::frame_allocator

The frame_allocator module provides a frame allocator for the kernel.

Structs

• FRAME_ALLOCATOR
• FrameTracker
  The FrameTracker struct represents a frame in the physical memory. It contains the frame number and is responsible for zeroing out the frame when it is created. It deallocates the frame when it is dropped, which follows the RAII idiom.
