Im trying to install Fedora 27 in my PowerPc but I can not boot it, I tested ubuntu and booted ok with yaboot, also tested openbsd and freebsd with openfirwmare boot. I saw this link https://github.com/masterzorag/G5_ppc64-linux but I can not replicate it or I did not understand why so many steps and why iso will not work for him.
I have problem with Nvidia driver in all tested distros... Any experience or recomendation ? Im user of Fedora about more than 8 years but I see for ppc64 some distros have less packages than others...

Subject: Compile Fedora with auto-vectorization

Should we start compiling Fedora with auto-vectorization, either using
-O3 or -O2 -ftree-loop-vectorize?
Downstream experimented with that for POWER 7 (the ppc64p7 packages).
But if auto-vectorization is beneficial on POWER, it likely helps on
other CPUs as well, given that SIMD support is quite common nowadays.
I really want to avoid a package-specific flag because I don't think
discussions about per-package build policies are a good use of our time,
and dependency changes invalidate previous decisions based on package
use all the time. (We saw a lot of that when we still had
package-specific hardening flags.)
We currently have the RPM macro _performance_build for that: It's used
in some Fedora spec files, but the redhat-rpm-config support have never
be contributed to Fedora. If we enable auto-vectorization globally,
those packages could remove the _performance_build setting, a minor cleanup.
