Thanks a lot for your patchset, I took a detail look at this patchset, and it looks good to me, I'm pretty happy that this patchset was backported from mainline kernel and you are the maintainer. For this patchset, Reviewed-by: Hanjun Guo <guohanjun(a)huawei.com> BTW, do we need updates for compiler, glibc and other usersapce package to recognize Hygon processor or performance optimization? if yes, you can send those patches to openEuler as well. And I kindly invite you to create a new SIG for Hygon processor in openEuler [1].
