After all, everything supports Svbare... After applying this series, a NOMMU kernel based on defconfig (changing only the three options below*) boots to userspace on QEMU when passed as -kernel. # CONFIG_RISCV_M_MODE is not set # CONFIG_MMU is not set CONFIG_NONPORTABLE=y *if you are using LLD, you must also disable BPF_SYSCALL and KALLSYMS, because LLD bails on out-of-range references to undefined weak symbols. * b4-shazam-merge: riscv: Allow NOMMU kernels to run in S-mode riscv: Remove MMU dependency from Zbb and Zicboz riscv: Fix loading 64-bit NOMMU kernels past the start of RAM riscv: Fix TASK_SIZE on 64-bit NOMMU Link: https://lore.kernel.org/r/20240227003630.3634533-1-samuel.holland@sifive.com Signed-off-by: Palmer Dabbelt --- d4b500cceb0e09ae22722d41454df6012848062b
