sabnzbd-riscv64

SABnzbd for RISCV64 ... with RISCV Vector instructions (RVV) in both sabctools and par2cmdline-turbo.

Specials:

• alpine, as it provides gcc 14, which is needed to compile RVV
• par2cmdline-turbo: updated config.guess
• unrar: remove "-march=native" so that it compiles
• sabnzbd: use python modules cryptography and cffi from alpine (not from pip, as that needs rust and a lot of compiling), and use them as --system-site-packages in the python venv.

Notes:

• Plain Ubuntu:24.10 is easier, but not compiled with gcc 14, so no RVV commands in sabctools and par2cmdline-turbo
• this docker image build does also work on x86 and ARM, but less necessary

Prepare

Running on your RISCV64: Bianbu, with docker (docker.io) installed

Check your docker setup is working:

docker run hello-world

If that fails because of permissions:

sudo docker run hello-world

Check your git setup is working:

git --version

build

On your RISCV64 board, execute this:

docker build -t="sanderjo/sabnzbd-riscv64" github.com/sanderjo/sabnzbd-riscv64.git#main

Building will take 15 minutes (on a Banana Pi BPI-F3, with SpacemiT K1 8 core RISC-V chip)

Check your build with:

docker images

The "make -j3" uses 3 cores, so you should see 3 cores jump to 100% (see screenshot). More cores might lock-up your system.

run

docker run -p 8080:8080 sanderjo/sabnzbd-riscv64

SABnzbd logging

SABnzbd should show these lines at startup: "SIMD set: RVV" and both par2 and unrar available:

rvv

During the build, if your RISCV64 supports RVV, you should see the list of RVV commands in the par2 binary:
