Hi, In this post we will explore FIO’s RTEMS port and how it can be used to benchmark RTEMS filesystems and drivers. First, let’s have a quick look at all the RTEMS filesystems: RTEMS FILESYSTEMS RTEMS supports mainly two types of filesystems: Network and Physical fs. Benchmarking support for networking filesystems isn’t yet available. However, nearly every other physical filesystem can be benchmarked and contrasted. Heap-based file systems are those which uses malloc() for file allocation. In other words, they reside completely on heap memory. These are mainly used to provide basic directory/file management even if there is no dedicated…
