This is the 5th version patchset to add the Linux kernel port for C-SKY(csky). Since I misunderstood the linux-next. I made some discrete patches which made review confusing. Now correct back to the whole patchset style. Thanks to everyone who provided feedback on the previous versions. This patchset adds architecture support to Linux for C-SKY's 32-bit embedded CPU cores and the patches are based on linux-4.19-rc3 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 Here is the pre-built cross compiler for fast test from our CI: https://gitlab.com/c-sky/buildroot/-/jobs/97941896/artifacts/file/output/images/csky_toolchain_csky_ck860_platform_defconfig_72371bf75a51f27ea59fc34eeaf236e06b75bf69.tar.xz 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 also can try C-SKY linux in a few steps with buildroot: $ 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.
