| Post subject: | Simple framework for developing filesystems in userspace |
Hello there. As I found a lot of trouble porting FatFS to my kernel I decided to create my own implementation of the filesystems (Fat32 and Ext2) that I plan to support. For that task, I decided to invest a few days in developing a framework to test the FS in userspace before running them on the kernel (for sake of my own sanity) As a way to contribute a bit to this awesome community, I'm posting the code: https://github.com/TretornESP/FUSED The aim is to emulate a FatFS-enabled disk driver but supported by a raw file. The development roadmap is: - Basic primitives (Read, Write, Startup, Status and IOCTL) - Lazy mode loading for the files (currently it just mmaps it, which is a bad idea for big files) - Buffer cache emulation (probably just introducing preconfigured delays on a miss, open to ideas) - SSD Wear emulation (gathering stats) In case you decide to give it a try, please don't doubt in asking any questions, I will gladly assist you! Thank you all! |
