“Session ID: BUD17-305 Session Name: Implementing contiguous page hint for anonymous pages in user space - BUD17-305 Speaker: Bamvor Jian Zhang Track: Kernel

★ Session Summary ★ Contiguous page hint is a feature in AArch32 and AArch64 which could decrease the number of TLB misses and improve the performance by sharing a single TLB entry across 16 4k pages whenever the pages are also physically contiguous. Currently, it is only used in hugetlb which limited the scenarios where it can be used. This session will share and discuss following things:

  1. The current design of hugepage, transparent hugepage and page Fault and proposal from Bamvor

  2. Compare and analyze the performance of different designs, including transparent hugepage, hugepage and Bamvor’ design.

  3. Discuss the scenarios which are suitable for this work beyond the enterprise. ————————————————— ★ Resources ★ Event Page: http://connect.linaro.org/resource/bud17/bud17-305/ Presentation: https://www.slideshare.net/linaroorg/bud17305-implementing-contiguous-page-hint-for-anonymous-pages-in-user-space Video: https://youtu.be/LZiPH4J8f0I —————————————————
