Project proposal: 64k kernel projectI propose a 64k kernel project. This project should contribute and support on an on-going basis: - A SPARC kernel which uses 64k pages instead of 8k pages ("dwarf pages") as default page size. The system should no longer use or support the usage of 8k pages
How would this work with network I/O? Do the IOMMUs support 64k pages? Do you really want to expose a 64k chunk of memory to IO just to DMA in a single ethernet packet?
- Necessary modifications to kernel modules to support the 64k page size mode (notable usage of hard coded 8k page size exists for example in the UFS module) - Necessary modifications to user land tools in ON to support the kernel 64k page size mode - Create the tools necessary to create, maintain and profile the kernel performance. The leaders initially will be Knut Reinert and myself. This project proposal has one (large) problem: We can only start this project if Sun is willing to contribute the changes of their own (abandoned) 64k kernel project - is this possible?
