For example, since it requires pages to be mapped +in kernel space in order to be used, the maximum amount of usable physical +memory is currently around 800MB (or 1.8GB if a 2/2 split is set). And +because the page allocator is unable to easily return blocks of contiguous +pages, the kernel has to use virtual memory to provide contiguity. +But the kernel virtual space is separate from the direct mapping of +physical memory, so the larger it is, the less physical pages available. +The size of the kernel space is currently around 200MB, with around 100MB +for kernel objects. This small size prevents the system from achieving +scalability, since a panic occurs when the kernel is unable to allocate +a kernel object such as a port. In addition, the kernel uses mainly tables +to store IPC rights. When a table is full, it is enlarged through a kernel +specific version of realloc(). When a file system starts managing many +files (e.g. because some of their content is cached in physical memory), +these tables can get big enough to make realloc() fail because of +fragmentation. + +The goal of this project is to make as much physical memory available as +possible for both the kernel and applications, by rewriting the page +allocator into a buddy allocator to support contiguous block allocations, +using it directly instead of virtual memory as the backend of the slab +allocator for kernel objects, and, if time allows it, transform IPC right +tables (e.g. into radix trees) and get rid of realloc(). + +This project requires a good understanding of virtual memory (both physical +mappings at the MMU level and virtual mappings at the VM level), and strong +skills in C programming.
