Resumo

We describe XOmB, an exokernel being developed to exploit the features of modern hardware. Specifically we discuss the use of large 64-bit virtual address spaces to provide a hybrid of segmentation and paging. This abstraction allows us to expose files and memory-mapped devices using the same mechanism. We also describe current work to develop a multicore scheduling mechanism that balances efficency and userspace flexibility.
