summary
Claim: mainline Linux 5.13 contains kernel XIP support for MMU‑enabled RISC‑V 64 targets and a real project fits Linux on a MaDoo board with 8 MB SRAM + 8 MB QSPI NOR by using XIP Linux and Buildroot. Measured non‑XIP kernel+root+app needed >8 MB RAM (kernel ~1+ MB RAM, root 1–4 MB, app ~2 MB); with XIP kernel shrinks to ≈250 KB flash/under 1 MB RAM and userland uses uncompressed executable sections on a special FS (serfs), enabling much lower idle power and faster boot.
