See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi all, below is a series to support nommu mode on RISC-V. For now this series just works under qemu with the qemu-virt platform, but Damien has also been able to get kernel based on this tree with additional driver hacks to work on the Kendryte KD210, but that will take a while to cleanup an upstream. To be useful this series also require the RISC-V binfmt_flat support, which I've sent out separately. A branch that includes this series and the binfmt_flat support is available here: git://git.infradead.org/users/hch/riscv.git riscv-nommu Gitweb: http://git.infradead.org/users/hch/riscv.git/shortlog/refs/heads/riscv-nommu I've also pushed out a builtroot branch that can build a RISC-V nommu root filesystem here: git://git.infradead.org/users/hch/buildroot.git riscv-nommu Gitweb: http://git.infradead.org/users/hch/buildroot.git/shortlog/refs/heads/riscv-nommu
