Hi Sascha,

I yesterday tried to compile the newest kernel 4.14 for my PS3 running
OtherOS++ and "Red Ribbon GNU Linux" from 2014. I even succeeded and
created the three *.deb files and installed them afterwards.

Unfortunately, my machine did not boot.

As far as I read in very old sources, this could be that my machine is
using OtherOS++ on firmware 3.55.2 and not the Sony OtherOS prior
firmware 3.2x.

I'm in contact with the creator from "Red Ribbon" and he mentioned we
have to manually patch PS3 linux kernel.

So, my question 1 would be: which patches would I need to get the newest
kernel 4.14 running on my PS3 machine?

I don't know about your machine with OtherOS++ on firmware 3.55.2,
but for FAT and DECR-1400 models with firmware 3.15 or lower the
otheros.bld built from the latest ps3-queue-v4.14 branch of my
ps3-linux repo using either ps3_petitboot_defconfig or
ps3_petitboot_nfs_defconfig will boot if written to flash memory
using ps3-flash-util or the XMB [Install Other OS].

Be aware that there was a kernel ABI breakage effecting kexec and
that the ps3-petitboot-09.11.30 I released cannot boot kernels newer
than linux-v3.15. See:

  https://www.mail-archive.com/debian-powerpc@lists.debian.org/msg66884.html (PS3?)

I'm working towards an updated petitboot release.

Question 2 would be: maybe there exists a second tree where we can get
the kernel for OtherOS++ too?

Sorry, I don't know.  You'll need to ask for help in the hacker
community for OtherOS++.

Maybe there is other stuff I am missing, but as far as I can tell the
sources compile beautifully on the PS3 powerpc machine. Only downside:
it takes 4-5 hours depending on what you selected in the step of "make
menuconfig"...

I highly recommend you cross compile on a PC.
