Efficient Copy-on-Write for Virtual-Memory Objects

Implementing classical, full-featured COW with multiple nesting levels would introduce substantial management overhead on the operating system side. Our goal with Morsels is to eliminate this overhead while retaining limited COW functionality.

Huge Pages for Virtual-Memory Objects

Currently, Morsels only support 4-KiB pages, but with larger page sizes the management overhead could be further reduced and the average memory access could be sped up, due to faster page-table walks and an increased TLB coverage.

Page Eviction for Shared Virtual-Memory Objects

The translation lookaside buffer (TLB) caches present page table entries, so that pages can not be unmapped by simply clearing the related page table entry. However, page eviction is vital for implementing advanced features like swapping and huge-page merging.
