DESCRIPTION:This talk surveys the RISC‑V isolation toolbox—spanning PMP
 /ePMP\, SPMP\, privilege levels\, virtualization\, Risc-V Worlds\, and eme
 rging Supervisor Domains—and shows how these mechanisms can be combined 
 to build scalable\, composable security and safety systems beyond traditio
 nal privilege separation.\n\nRISC‑V has steadily developed a rich and di
 verse set of isolation mechanisms\, including ePMP for physical memory pro
 tection\, privilege levels for execution control\, page‑based virtual me
 mory for scalable address isolation\, hypervisor extensions for virtualiza
 tion\, and Worlds for hardware‑enforced compartmentalization. Each of th
 ese tools addresses different isolation challenges\, from resource‑const
 rained microcontrollers to full server‑class systems.\n\nModern platform
 s increasingly demand fine‑grained\, composable isolation rather than co
 arse\, monolithic privilege separation. Mixed‑criticality systems\, safe
 ty‑certified embedded platforms\, and confidential computing environment
 s all require isolation techniques that can be layered\, combined\, and ad
 apted to different threat models and deployment constraints.\n\nThis talk 
 presents a toolbox‑oriented view of RISC‑V isolation.\n\nSupervisor Do
 mains are introduced as an emerging architectural direction within this to
 olbox\, exploring finer‑grained isolation within supervisor mode itself.
  While still evolving\, Supervisor Domains illustrate the broader move bey
 ond privilege levels toward more modular and composable execution domains 
 and provide a useful lens for understanding how future RISC‑V systems ma
 y further decompose trusted software.
