We just published an initial preview version of our next kernel-uek. This is based on upstream Linux 4.14 (latest stable -14). UEK4 is/was based on a 4.1 upstream Linux kernel.
If you want to try it out, you can just add the yum repo below on your Oracle Linux 7-based system. If you don't have a quick OL7 environment, remember you can sign up for a free account on Oracle Cloud and quickly create an Oracle Linux 7 instance and do exactly the same.
There will be very regular updates of this preview kernel going forward so you can remain up to date with our development efforts. The source code is there as well and we are going to push the git repos onto github/oracle soon(ish).
All you have to do is add the following to your /etc/yum.repos.d/public-yum-ol7.repo file.
[ol7_developer_UEKR5] name=Oracle Linux $releasever UEK5 Development Packages ($basearch) baseurl=http://yum.oracle.com/repo/OracleLinux/OL7/developer_UEKR5/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1and then upgrade your kernel
# yum upgrade kernel-uekreboot and you are all set.
If you want the latest dtrace along with it, it's in the same repo, you can just do
# yum install dtrace-utils Do a dtrace -l, you can see there are over 5000 probes now!
