Applications and Porting / [GAME] yQuake2 runs perfectly :D
« on: April 10, 2020, 11:04:51 pm »
The https://github.com/yquake2/yquake2 port is actually one of the best Quake 2 port atm. Firstly it supports wide range of renderers, from Software to Vulkan. Secondly the author is very active. Thirdly the codebase can be compiled easily for Linux ppc64le without any issue.

Applications and Porting / Re: Dolphin emulator works without JIT

What do you mean when you say 'KVM-able'?

Applications and Porting / [GAME] Dolphin emulator works without JIT
« on: April 05, 2020, 07:10:36 am »
Dolphin emulator can be compiled on any LE platform. Because of lacking JIT, the performance is dreadful.

The dev team is not so much interested in support ppc64le at this stage because they do not have access to a workstation.

I've been looking around for the Docker CE (ppc64le) binary for Debian buster. Docker does not offer ppc64le package for Debian (source: https://docs.docker.com/install/linux/docker-ce/debian/)

The only source I could find is this post from IBM https://developer.ibm.com/linuxonpower/docker-on-power/ which has links to Unicamp repository. Unfortunately that repo has old version.

Wondering if anyone know of a maintained repo with up-to-date Docker CE packages?

UPDATE: AFAIK there is no official packages from K8S or Debian, however the new K8S comes witth kubepkg tooling which could be used to build debian packages. Here is the link to built DEB packages https://github.com/runlevel5/kubernetes-packages

Much thanks in advance

Another emulator that does the job very well is RetroArch with Beetle PSX HW core. Highly recommended!

I also learn that packer does support building qemu virtual machine. And there are quite a number of templates available if you are lazy to bake your own.

Here is one https://github.com/osuosl/packer-templates

Thanks for the reply.

I resolve the issue by using `pseries` as machine.

I am trying to create virtual machine to run Ubuntu 18.04 PPC64LE with QEMU and KVM_HW module.

Below is my config:

Code: [Select]
<domain type="kvm">
  <name>ubuntu18.04</name>
  <uuid>f121409d-6da7-49f2-ba86-e8e87ee26398</uuid>

    </libosinfo:libosinfo>
  </metadata>
  <memory>4194304</memory>
  <currentMemory>4194304</currentMemory>
  <vcpu>16</vcpu>

    <boot dev="hd"/>
  </os>
  <cpu mode="custom" match="exact">

  </cpu>
  <clock offset="utc"/>

    <disk type="file" device="disk">
      <driver name="qemu" type="qcow2"/>
      <source file="/root/.local/share/libvirt/images/ubuntu18.04.qcow2"/>
      <target dev="sdb" bus="sata"/>
    </disk>
    <disk type="file" device="cdrom">
      <target dev="sda" bus="scsi"/>
      <readonly/>
    </disk>
    <interface type="network">
      <source network="default"/>
      <mac address="52:54:00:16:bd:e5"/>
    </interface>
    <console type="pty"/>
    <graphics type="vnc" port="-1"/>
    <video>
      <model type="vga"/>
    </video>
  </devices>
</domain>

When I start the virtual machine, I got error:

Code: [Select]
Unable to complete install: 'internal error: qemu unexpectedly closed the monitor: 2020-03-29T05:54:00.894965Z qemu-system-ppc64: invalid chip model 'host' for powernv9 machine'

which is a bit peculiar because my host is actually POWER9 and AFAIK the Sforza POWER9 that Raptor CS offers for Blackbird system does support PowerNV (I could confirm that by grepping for PowerNV in /proc/cpuinfo).

I would like to ask if anyone could give me guidance to troubleshoot this issue. Much thanks in advance

Do you have any suggestion? I am not aware of any UE4-base game that offers ppc64le binary atm.

401
I haven't tried any PS2 yet. Going to give GC a go first because I really want to finish the Zelda: Wind Walker this time.

Screenshots from running mednafen


403
Been wondering if anyone has experimented with any working PSX emulator? I've tried PCSXR which crashed because the Pete's OpenGL plugin got segmentation fault. I also have tried the mednafen emulator with no success (only the bios pops up).

UPDATE:

I managed to get PCSXR and mednafen (compiled from sources) run PSX games

Blackbird / Re: Where is the internal USB header pin?
« on: March 11, 2020, 06:00:54 pm »
Weirdly both J10105 and J10106 points to the same port in the manual.

Blackbird / Where is the internal USB header pin?
« on: March 11, 2020, 07:53:32 am »
I am a bit lost after the reading the user guide manual v1.0 PDF

On page 30, the J10106 is said to be the internal USB header. Yet... page 22 TPM also points to the same port...?!
