[PATCH V8 00/21] C-SKY(csky) Linux Kernel Port
From: Guo Ren
Date: Fri Oct 12 2018 - 00:43:44 EST
This is the 8th version patchset to add the Linux kernel port for
C-SKY(csky) based on linux-4.19-rc3.
In this patchset, we fixup make allmodconfig and remove one callback
in smp.c with irqchip's feedback.
Here is the LTP test report for this patchset:
(and add "V12 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://github.com/c-sky/csky-linux
ABI Documentation: https://github.com/c-sky/csky-doc
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
