This interface is a set of operations added to a previously + proposed virtual instruction set architecture called LLVA (Low Level Virtual + Architecture) and can be implemented on existing processor hardware. The + long-term benefits of such an interface include + richer OS-information for hardware, + greater flexibility in evolving hardware, + and + sophisticated analysis and optimization capabilities for kernel code, + including + across the application-kernel boundary transformations. + Our interface design (LLVA-OS) contains + several novel features for machine-independence and performance, including + efficient saving and restoring of (hidden) native state, + mechanisms for error recovery, and several primitive + abstractions that expose semantic information to the underlying translator and + hardware. We describe the design, a prototype implementation of LLVA-OS + on x86, and our experience porting the Linux 2.4.22 kernel to LLVA-OS. + We perform a performance evaluation of this kernel, identifying and + explaining the root causes of key sources of virtualization overhead. + </blockquote> + + <h2>Published:</h2> + <blockquote> + "A Virtual Instruction Set Interface for Operating System Kernels", John Criswell, Brent Monroe, and Vikram Adve.<br> + Workshop on the Interaction between Operating Systems and Computer Architecture (WIOSCA '06), Boston, Massachusetts, 2006. + </blockquote> + + <h2>Download:</h2> + <ul> + <li><a href="2006-06-18-WIOSCA-LLVAOS.pdf">A Virtual Instruction Set Interface for Operating System Kernels</a> (PDF)</li> + <li><a href="2006-06-18-WIOSCA-LLVAOS.ppt">A Virtual Instruction Set Interface for Operating System Kernels</a> (slides)</li> + </ul> + + </body> + </html> Index: llvm-www/pubs/2006-06-18-WIOSCA-LLVAOS.pdf Index: llvm-www/pubs/2006-06-18-WIOSCA-LLVAOS.ppt _______________________________________________ llvm-commits mailing list llvm-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits
