Sergey Bugaev	118cb391dd	VM: Pass a PhysicalPage by rvalue reference when returning it to the freelist. ... This makes no functional difference, but it makes it clear that MemoryManager and PhysicalRegion take over the actual physical page represented by this PhysicalPage instance.	2019-06-14 16:14:49 +02:00
Conrad Pankoff	aee9317d86	Kernel: Refactor MemoryManager to use a Bitmap rather than a Vector ... This significantly reduces the pressure on the kernel heap when allocating a lot of pages. Previously at about 250MB allocated, the free page list would outgrow the kernel's heap. Given that there is no longer a page list, this does not happen. The next barrier will be the kernel memory used by the page records for in-use memory. This kicks in at about 1GB.	2019-06-12 15:38:17 +02:00
