The (First?) CHERI Microkernel Workshop

On 23 April 2016, adjacent to EuroSys 2016 in London, the University of Cambridge hosted a workshop to investigate potential uses for CHERI in microkernel design. The event included attendees from Cambridge, SRI, ETH Zurich, George Washington University, TU Dresden, ARM, Broadcom, Google, Hewlett Packard Labs, and Oracle, who presented on various current microkernel designs and capability models, the CHERI instruction-set architecture, and potential new directions in operating-system design supported by architectural change.
