Applications and Porting / Re: [GAMES] Quake 3 source port with Vulkan renderer (vkQuake3)

It's pretty much straight-forward changes. I would really appreciate if PPC guru members could review and chime in the PR because I know the core team of ioquake3 might not be well versed in PPC so they might be hesitated in merging the changes.

It's nearly there! I hope today I could get the PR polished for merger.

@ClassicHasClass I would really appreciate if I could get your guidance and support as I start adding more PPC-specific features into ispc. Great thanks in advance

Thanks, that indeed fixes the build issue for me. But I'm still getting the same runtime issue as before - a segfault after loading the first level.

Please run the game with gdb and paste the stacktrace to gist.github.com or pastebin and share the link here

Okay I added a basic support PPC64LE

It's pretty much straight forward changes https://github.com/ispc/ispc/pull/3735

at this stage it has no PPC-specific ISPCTarget enum values, no ISA enum entry, no .ll builtin files. I hope this would create the foundation for developers to further extend it.

I built dxc and it seems to be recognized by RBDOOM, but I'm getting a build error:
[ FAIL ] SPIRV builtin/lighting/interactionSM.vs.hlsl {main} {USE_GPU_SKINNING=1 LIGHT_POINT=1 LIGHT_PARALLEL=0 USE_PBR=1 USE_NORMAL_FMT_RGB8=1 USE_SHADOW_ATLAS=1}

I did not run into such issue,

```

# build dxc
git clone https://github.com/microsoft/DirectXShaderCompiler.git
cd DirectXShaderCompiler
git submodule update --init --recursive
mkdir build && cd build
cmake .. -C ../cmake/caches/PredefinedParams.cmake
make dxc -j
sudo make install-dxc
# build the shared library
make dxcompiler -j32
# install it
sudo make install-dxcompiler
# then update the library cache:
sudo ldconfig


# build game
git clone https://github.com/RobertBeckebans/RBDOOM-3-BFG.git
cd ./RBDOOM-3-BFG/
git submodule update --init --recursive
mkdir build && cd build
export DXC_CUSTOM_PATH=/usr/local/bin/dxc
../neo/cmake-linux-debug.sh
cd ../build
make -j32
```

Applications and Porting / [DEV] Need help with testing htop-rs

« on: January 27, 2026, 03:41:19 am »

htop-rs is basically an experiment to port C htop to Rust.

It's not feature complete yet but I hope to get a bit of feedback from the community in regards to the PPC64LE Linux build

It looks like the newest version requires Microsoft's DXC which doesn't seem to be available in Portage and is itself an LLVM fork, so I expect getting it to build might be some work in itself. The last version that doesn't require it is 1.4.0.

You have to build DXC manually from source. Building it is quite straightforward, no patches required at all

Applications and Porting / [DEV] Proposal to drop PPC64 BE support in the next version of Golang

« on: January 19, 2026, 07:03:14 am »

See https://github.com/golang/go/issues/76244

It's unfortunate that Go might drop support for PPC64BE for real. That means many Golang-based softwares will cease running on POWER8 or even POWER5 G5 PowerMac.

Operating Systems and Porting / Re: FreeBSD 16 plans to drop support for PPC64.

« on: November 26, 2025, 04:24:35 pm »

We'd like to retire powerpc64 and powerpc64le just before the FreeBSD stable/16 branch.

It would be a great disappointment if FreeBSD drop support for PPC64. I find FreeBSD extremely useful for hosting ZFS.

In that case, reply to the mailing list. If no one replies about using FreeBSD on POWER, the conclusion will be that it's unused code ready for removal.
FYI, I already replied. Note that you need to be subscribed to reply.

I am still trying to figure out how to get the mailto to respond to the message. If you happen to know how to do so for mlmmj-based mailing list, please point me to the right place. Many thanks in advance

Applications and Porting / [DEV] Electron support for ppc64le

« on: November 04, 2025, 05:47:04 pm »

Electron is a well known web-based stack for cross-platform application development. It is not my cup of tea but many popular apps such as VS Code, Atom, Slack, etc are built with it. So having it support ppc64le upstream is definitely a big win for us all.

There is a ticket https://github.com/electron/electron/issues/15691 to gather efforts from the community to get the support implemented. lex-ibm has been maintaining his own build script which is known to work well up to v37. Because he is occupied with other priorities, it would be great if any member could give him a hand to:

* Get his build script to support latest v39
* Extract all patches and submit PRs upstream
