Hi, all

We use AMD Rome CPUs, like EPYC 7452.
RHEL said that RHEL 7.6.6 began to support these cpus(detials:
https://access.redhat.com/support/policy/amd)
, but we found that  CentOS7.6 with kernel 3.10.0-957.21.3.el7.x86_64 also
works fine.
So, my questions are:
1) Is there any place that i can find the cpu support info?
2) Dose the kernel 3.10.0-957.21.3.el7.x86_64 from CentOS7.6 already
contains changes made by kernel 3.10.0-957.27.2.el7 from RHEL7.6?
3) Does the kernel update has a release note or something like that and
where to find ?

Any suggestions will help !
Thanks
