Emerging byte-addressable non-volatile memory (NVM) has the advantages of fast, cheap and persistent, and is considered as the next generation of persistent memory. However, existing NVM-based filesystems cannot adapt well for mobile devices, and not to mention the consideration for mobile application characteristics. In this paper, we propose an efficient and durable in-memory file system named as Mobi-PMFS for mobile devices. Proposed Mobi-PMFS is not only adaptive to ARM architecture, but also customized according to mobile application features. A wear-aware three-list space management scheme including a switching allocation algorithm is proposed to provide optimum performance for mobile systems while keeping the durability of NVM. Experimental results show that Mobi-PMFS is 8x times and 1.2x faster than EXT4-SSD and EXT4-DAX, and provides 11x wear-leveling improvement compared with the original PMFS. |
