people on this list with years of experience of PPC CPUs who may be able to help.

Hi all,
I've just done a git pull and rebuilt master on my Mac Mini G4 in order to test

Hi all,
Referencing my bug report over on the kvm-ppc list at
https://www.spinics.net/lists/kvm-ppc/msg14971.html, I've been experiencing a
