Hello Pirmin,
- should cached_fs_rom theoretically work on base-linux, or is there an inherent restriction that prevents this?
unfortunately not. The cached_fs_component relies on core's RM service for the on-demand population of (remote) address spaces to enforce read-only memory mappings at the client side.
Unlike the various microkernels, Linux does not provide an appropriate mechanism for the remote manipulation of virtual address spaces.
Cheers Norman
