[PATCH V4 00/27] C-SKY(csky) Linux Kernel Port

From: Guo Ren
Date: Wed Sep 12 2018 - 09:25:25 EST


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.
