Losing this when you load ELFs is kind of a bummer. Probably a dumb question but I wonder if it'd be possible to only swap in the parts of the binary that are needed at any given time.
- ValdikSS 9mo agoswap requires MMU, so no, unfortunately. But there are tricks to have XIP userspace: cramfs supports it, as well as a special AXFS file system. cramfs parses ELF files and marks XIP only a .text/ro segments of it, not the whole file. https://github.com/npitre/cramfs-tools/commit/2325ed2de8fd1781cbf36ca31797de1d306ccb8e https://github.com/npitre/cramfs-tools/commit/2325ed2de8fd17...
- actionfromafar 9mo agoHistorically, Unix SVR7 and Minix had swap with no MMU. But Linux can't do it.
