source of reference: Second Level Address Translation (The Free Encyclopedia WikipediA) last edited on 5 August 2021, at 20:45 UTC, URL: https://en.wikipedia.org/ Second Level Address Translation (SLAT), also known as nested paging, is a hardware-assisted virtualization technology which makes it possible to avoid the overhead associated with software-managed shadow page tables. AMD has supported SLAT through the Rapid Virtualization Indexing (RVI) technology since the introduction of its third-generation Opteron processors (code name Barcelona). Intel's implementation of SLAT, known as Extended Page Table (EPT), was introduced in the Nehalem microarchitecture found in certain Core i7, Core i5, and Core i3 processors. ARM's virtualization extensions support SLAT, known as Stage-2 page-tables provided by a Stage-2 MMU. The guest uses the Stage-1 MMU. Support was added as optional in the ARMv7ve architecture and is also supported in the ARMv8 (32-bit and 64-bit) architectures. [Implementations] Rapid Virtualization Indexing Rapid Virtualization Indexing (RVI), known as Nested Page Tables (NPT) during its development, is an AMD second generation hardware-assisted virtualization technology for the processor memory management unit (MMU). A VMware research paper found that RVI offers up to 42% gains in performance compared with software-only (shadow page table) implementation. Tests conducted by Red Hat showed a doubling in performance for OLTP benchmarks. RVI was introduced in the third generation of Opteron processors, code name Barcelona. |
