I am going to attempt to ask Google to support ppc64le with their toolings. Wish me luck.

Applications and Porting / [APP] Discourse now runs on Linux ppc64le
« on: March 08, 2020, 05:59:36 pm »
EDIT: Thanks to the work by lloeki https://github.com/sqreen/ruby-libv8-node/issues/11, Discourse now works out-of-the-box on ppc64le
Discourse is a great forum software which is written in Ruby-based framework Ruby On Rails.At one stage I believe RaptorCS was considering using Discourse however they went with Simple Machines Forums instead because libv8 rubygem does not support ppc64le.
In theory it is possible to build libv8 rubygem for ppc64le linux because the upstream v8 library has supported ppc64. I've spent a bit of time trying to get v8 7.3.495 compiled by substituting Google's toolings (such as cpython, git) with the stock toolings. For more details, please have a look at https://github.com/runlevel5/v8-ppc64le. It's going to take time for me to follow up with the libv8 maintainer to work out a way to set up automated build for ppc64le. For the time-being, we could go with custom-built gem.
Another hurdle that I overcome is to get mini_suffix gem to run on ppc64le. That gem does not ship with libpsl for linux ppc64le. I've created a patch which is waiting for approval. Users could fetch the branch, build the custom gem with `
That's pretty much it.

Applications and Porting / [DEV] Build ppc64le binary for rubyjs/libv8 rubygem
« on: March 08, 2020, 09:26:58 am »
Few weeks ago, I was asking why Raptor did not choose Discourse as the forum platform. It turns out that libv8 gem does not support ppc64le because .... Google does not offer an easy way to build v8 library out of the box.
Well, I've spent 2 days to learn how to get v8 to compile and managed to build custom libv8 gems which could satisfy the requirement of Discourse.
If you are interested in how, feel free to have a look at my https://github.com/runlevel5/v8-ppc64le

Thanks for documenting it.
It would be great if this issue is addressed in the upstream Ubuntu.
What do you think about lodging a ticket with Ubuntu folks?

If it is polaris 12, the most recent amdgpu in Linux 5.4 should support that card out of the box.
If you want to be sure, buy yourself a Vega10 or 12 cards such as RX Vega 56 or 64. Those cards are confirmed to run perfectly on the host Linux.

Applications and Porting / [DEV] How to install Elasticsearch 7.4.2 for Linux ppc64le?
« on: March 01, 2020, 06:53:18 am »
AFIK ES does not officially support PowerPC and I am not aware of any custom distribution that support linux ppc64le.
Because ES is written in Java, that means it is super trivial to get it compiled under linux ppc64le host.
If you are interested in how, please have a look at my build script

Firmware / Troubleshooting sshd openbmc host via port 2200 after upgrading to 2.0

Applications and Porting / [GAME] Attempt to compile Unreal Tournament 4 on Linux ppc64le - in progress
« on: February 22, 2020, 03:25:51 am »
Unreal Tournament 4 is one great game by EPIC GAME which was developed in crowd sourcing model.
The game development was ceased indefinitely however the community has been keeping it going a bit further out of the official EPIC GAME git repo.
I am not a big fan of this game however I am very curious on getting it compiled and run under vulkan mode to test out my AMD Radeon Vega 64 card.
I have been following the guide by Raptor CS https://wiki.raptorcs.com/wiki/Software/ThirdParty/Guides/Epic/UnrealTournament4. If I understand the context of that guide correctly, Raptor Engineering's Timothy added support for PowerPC by forking from a community fork which added support for Unreal Engine 4.20.
The first hurdle is to build Unreal Engine 4.20 on my Fedora 32 (rawhide) by following instructions on the https://wiki.raptorcs.com/wiki/Software/ThirdParty/Guides/Epic/UnrealEngine
I have got to the steps of compiling libdwarf:
The source code does not include the `build_native` script. I think Timothy forgot to push that script to the repo OR there might be a missing step to generate that script which was not documented.
Either way, I am trying to unblock myself from this issue by learning the similar script for libelf to see if I could replicate for libdwarf.
Wish me luck

I am not so familiar with DarkPlaces to answer your question. I think it is just as good as vkQuake / QuakeSpasm.
I love to dig in FTEQW a bit more when I have more free time for gaming.

Blackbird / Support for POWER9 22core?

The official product page of blackbird stated that the motherboard support up to 8-core POWER9. Wondering if it is possible to use the POWER9 22core?
