Re: [CentOS-devel] [CentOS-announce] Release for CentOS Linux 7 (1804) on POWER9 (ppc64le)
2018-08-15 20:26 GMT+02:00 James O'Connor jpoc@linux.vnet.ibm.com:
I am pleased to announce the general availability of CentOS Linux 7 (1804) for POWER9 processors (ppc64le - powerpc 64-bit little endian). This release is derived from Red Hat Enterprise Linux 7.5 ALT.
Note this release is 99% equivalent to the existing CentOS 7 Linux 7 (1804) for POWER8 processors (ppc64le - powerpc 64-bit little endian). The key difference being that kernel-4.14.0 is used for POWER9 enablement and kernel-3.10.0 is used for POWER8 enablement.
You will find the CentOS 7 (1804) Power9 installation images here:

A special thank you to Johnny Hughes and Pablo Greco for their assistance making this release possible.
This is a great news. Can we have a power9 arch repo in http://mirror.centos.org/altarch/7/virt/ as well? I guess other SIGs are in same situation.

$basearch on Power9 is still ppc64le, so it should just work ? At least that's what I was told, as we have no Power9 to test it :)

Can anybody with a power9 environment test it and give feedback?

Looks like to me that this issue is what arch is supported by qemu-kvm, right? Or there is an error caused by the new lorax/anaconda tree.
You could, theoretically, install the VM from ppc64le tree, then change your repo files to point to the power9 tree and upgrade.
I think the stock ARCH type from qemu would be ppc64le (power8) and its not really emulating power9, right?

The ONLY items changed from base ppc64le are:
kernel (and all the things that SRPM produce) anaconda (and all the things that SRPM produce)
Besides the binary RPMs produced from those SRPMS .. everything else is just ppc64le built items hard linked in.
So, theoretically the only items that would have an issue would be things that require the 3.10.0 RHEL based kernel and not the kernel-alt (4.14.0 based) .. or that depend on anaconda.
If you want/need to BUILD something against kernel-alt or the new anaconda instead of the base os ones .. we will need to get that set up in CBS.
