Freescale P5020 cpu will be kvm-pr?

From: luigi burdo <hidden>
Date: 2016-02-29 19:08:41 

Hi all,sorry for this email but i need to ask to  Alexander Graf and Michael Ellerman if will be possible have kvm and kvm-pr for the Freescale/Nix P5020 cpu . We are testing a new desktop machine with this powerpc cpu classesand right now we see kvm under qemu is working only on emb side, this because the kernelset the e5500 cpu as a emb and there is no an option for build the kernel with book3s.

here are the new machine specs:http://www.vincentperkins.com/AmigaNG/x5000.php 
Thanks for your time and sorry for my English

KVM for e5500 uses hardware hypervisor features.  PR-mode KVM is not
supported.  Nested KVM is not supported.

p5020 uses an e5500 core which is book3e.  You cannot use a book3s kernel with
it.  Why would you want to?

I don't know what you mean by "working only on emb side".

Hi Scott, thanks for the reply,about: I don't know what you mean by "working only on emb side".thru qemu 2.5 i can use only ppcemb as kvm not ppc64 or ppc 
Dont have the Kvm-pr is a really unhappy news, it means we will not have the opportunity to run for example Mol-kvm on  this machine.
about:KVM for e5500 uses hardware hypervisor featureslook like hypervisor is disabled because the main Hardware is too young and need a better knowledge.

Thanks for your time and infos

Oh, you mean the QEMU target... "ppc64" should work.

Right.  KVM on book3e does not allow making the CPU look like a different type
of PPC.  It just lets you create virtual instances of the same CPU.

about:KVM for e5500 uses hardware hypervisor features
look like hypervisor is disabled because the main Hardware is too young and
need a better knowledge.
Not sure what you mean here.

Is there anything particular about that log that you are concerned about?

hi Scott,
the P5020 mmu is signed by the kernel no book3e found=20
kvm ppc64 crash if run by qemu.
in the kernel( 4.5 too)all is enabled we had a base .config by freescale/nix=
=20
where kvm options and book3e  where enabled.
my suspect is this can be an generated issue by  the host uboot or a missed t=
db parameter and not a linux kernel problem.
Just was need an expert point of view .

qemu: fatal: This KVM version does not support PAPR
You need to tell QEMU to use the appropriate CPU type (e5500) and platform

Hi Scott,
this is my Kernel 4.5 dmesg 

dmesg | grep -i MMU

None of these messages are a problem.

"Book3E HW tablewalk" is for e6500, not e5500.  fsl-hv is for the Freescale
Embedded Hypervisor (Topaz), not KVM.

i attached my kenrel .config

My qemu-ppc-64 crash, note i have the same crash 

qemu: fatal: This KVM version does not support PAPR
You need to tell QEMU to use the appropriate CPU type (e5500) and platform
(ppce500).  PAPR is for book3s, which is what QEMU defaults to.
