Release, which has been through 10 rounds of review on mailing list. We almost got the Acked-by/Reviewed-by of all patches except "Process management and Signal", but all've been tested. Here is the LTP-20180118 test report: ----------------------------------------------- Total Tests: 1298 Total Skipped Tests: 281 Total Failures: 10 Kernel Version: 4.19.0+ Machine Architecture: csky Hostname: buildroot ----------------------------------------------- This patchset adds architecture support to Linux for C-SKY's 32-bit embedded There are two ABI versions with several CPU cores in this patchset: ABIv1: 610 (16-bit instruction, 32-bit data path, VIPT Cache ...) ABIv2: 807 810 860 (16/32-bit variable length instruction, PIPT Cache, SMP ...)

"LTP, Lmbench ..." will be tested for every commit. See here for more details: https://gitlab.com/c-sky/buildroot/pipelines We'll continouslly improve csky subsystem in future" Arnd acks, and adds the following notes: "I did a thorough review of the ABI, which as usual mainly consists of spotting any files that don't use the asm-generic ABI itself, and having it changed to it matches exactly what we do on other new architectures. I also looked at every other patch and commented on maybe half of them where I saw something that did not quite seem right. Others have reviewed specific patches in greater depth. I'm sure that one could fine more of the minor details, but as long as they are not ABI relevant, they can be fixed later. The only patch that is part of the ABI and that nobody reviewed is the signal handling. This is one of the areas I never worked on in much detail. I did not see anything wrong with it, but I also don't know what the problems with the other architectures are here, and we seem to be hitting issues occasionally, and we never managed to generalize this enough for new architectures to have a trivial implementation. I was originally hoping that we could have the 64-bit time_t interfaces ready in time to completely drop the 32-bit ones, but that did not happen. We might still remove them in the next merge window depending on whether the libc upstream people prefer to keep them or not. One more general comment: I think this may well be the last new CPU architecture we ever add to the kernel. Both nds32 and c-sky are made by companies that also work on risc-v, and generally speaking risc-v seems to be killing off any of the minor licensable instruction set projects, just like ARM has mostly killed off the custom vendor-specific instruction sets already. If we add another architecture in the future, it may instead be something like the LLVM bitcode or WebAssembly, who knows?"
