Yesterday I had the idea to modify the problematic patch [1] so that it applies on ppc64el only but not on powerpc and ppc64. This should at least fix the console problem. Adrian[1] https://salsa.debian.org/kernel-team/linux/-/blob/debian/latest/debian/patches/bugfix/powerpc/fbdev-offb-Update-expected-device-name.patch?ref_type=heads
So, I've been reading about this patch, trying to find out the
purpose of changing the property name. I'm wondering why fbdev
offb code is failing to find the display, as all changes look they
are within offb. So, IIUC, the kernel fbdev module is expecting "of-display.0"
from modern OF compatible firmware but Apple OF is providing "of-display".
Am I on track or off?
