This is the 7th version patchset to add the Linux kernel port for C-SKY(csky) based on linux-4.19-rc3. In this patchset some fixup patches are folded into original patch in order to make review clearly and reduce the patches' number for upstream patchset. The changelog is added in the every patch's commit-msg. Here is the LTP test report for this patchset: (and add "V10 C-SKY(csky) Linux Kernel Driver" patchset) ----------------------------------------------- Total Tests: 1298 Total Skipped Tests: 280 Total Failures: 11 Kernel Version: 4.19.0-rc3+ 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: 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 The development repo: https://gitlab.com/c-sky/csky-linux Here is the pre-built cross compiler for fast test from our CI: https://gitlab.com/c-sky/buildroot/-/jobs/101608095/artifacts/file/output/images/csky_toolchain_qemu_csky_ck807f_4.18_glibc_defconfig_482b221e52908be1c9b2ccb444255e1562bb7025.tar.xz 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 Any feedback is welcome.
