This is the 3th version patchset to add the Linux kernel port for C-SKY(csky). Thanks to everyone who provided feedback on the previous version. This patchset adds architecture support to Linux for C-SKY's 32-bit embedded CPU cores and the patches are based on linux-4.18.4 There are two ABI versions with several CPU cores in this patchset: ABIv1: ck610 (16-bit instruction, 32-bit data path, VIPT Cache ...) ABIv2: ck807 ck810 ck860 (16/32-bit variable length instruction, PIPT Cache, SMP ...) More information: http://en.c-sky.com I'm from Hangzhou,China C-SKY Microsystems and responsible for C-SKY Linux port. The development repo is https://gitlab.com/c-sky/csky-linux We use buildroot as our CI-test enviornment. "LTP, Lmbench ..." will be tested for every commit. See here for more details: https://gitlab.com/c-sky/buildroot/pipelines You can try C-SKY linux in a few steps: $ git clone https://gitlab.com/c-sky/buildroot.git $ cd buildroot $ make qemu_csky_ck807f_4.18_glibc_defconfig $ make It will download "linux glibc gcc binutils qemu busybox" source code and build them into one image. How to run, See: https://c-sky.gitlab.io/-/buildroot/-/jobs/95233371/artifacts/output/images/readme.txt Any feedback is welcome.
