I'm wondering whether Rich could kindly elaborate a little bit more details about this concern ? Since my employer, Andes Tech, is one of the founding plantium memeber of RISC-V Foundation and we're shipping a considerable amount of Linux-running RV32 products at the time we're speaking, we will be happy to help on the kernel side and make it more stablized and secured. During my pastime, I've ported Alpine Linux with musl 1.2.0 to a publicily available and open-sourced platform, LiteX/VexRiscv[1], which could be synthesized and "burnt" to a Lattice ECP5-5G Versa Evaluation Board with completely FOSS toolchain without any closed source component. [2] And here's the footage of booting : https://asciinema.org/a/315205 Unfortunately, since my musl 1.2.0 is an inhouse work and we are still polishing and preparing it for upstreaming, please excuse me from not releasing the cpio image and stuffs at this time being. P.S. Regarding the last mail: https://www.openwall.com/lists/musl/2020/03/13/4 I'm not really qualified to answer the reason/profit of lacking LR/SC pair. Yet just a rough hunch that LR/SC is much stronger in atomicity than other AMOs. Best regards and looking forward to the prosperity, Ruinland ChuanTzu Tsai [1] https://github.com/litex-hub/linux-on-litex-vexriscv [2] https://symbiflow.github.io/
