@cwt mentioned this to me today.
If you are rust-lang fan, create this file:
cat .cargo/config.toml
[net]
git-fetch-with-cli = true
[profile.release]
opt-level = 3
debug = false
lto = 'thin'
strip = true
[target.riscv64gc-unknown-linux-gnu]
rustflags = ["-C", "target-cpu=sifive-u74", "-C", "target-feature=+m,+a,+f,+d,+c,+zba,+zbb"]
It will help squeeze every last piece of performance generating VF2-specific binaries from your rust-lang compiler and cargo. If you haven’t tried rust, please do. It’s well worth it the investment in effort.
and
are great reference points on how to build great apps with rust.
czkawka supports many different gui sdks, and among them slint . Worth the read.

hello, I use the same configuration for mpv on sway, my mpv cannot play videos however.It is core dumped.What is yout environment variable, I found that the default value of WLR_RENDER_DRM_DEVICE is /dev/dri/card1, which is not a drm node.

我看见你的截图上有中文，所以我用中文回答你，我英文不好。我只是个普通用户，我的mpv配置是试错多，试出来的。而且我的显示器是1k屏，不如你的4k屏。如果你播放流畅就应该是GPU使用正确了吧 http://forum.rvspace.org/t/vf2-mpv-mkv-vlc/4101/2?u=lzzhzh
Hi,
The repo (not cwt) just needs to catch up the new mkinitcpio which requires systemd 255.4.

The patched mesa is based on mesa 22.1.7, which is already 19 months old. Shouldn’t most of the patches applied in the pkgbuild be mostly obsolete by now, as the things they fix/add have already been fixed/added upstream?

The new kernel packages are ready, the new image should be done on Monday.
You can also use this script to update the kernel.

Sorry for the delay, the new image cwt21 is here Release cwt21 · cwt-vf2/archlinux-image-vf2 · GitHub .
I didn’t have time to update the post yet, will do it tonight or tomorrow.

I wanted to share some important updates regarding the cwt21 kernel. Previously, I had been using clang as the default compiler for the kernel since the very beginning. However, the latest version of clang (clang-17) on Arch Linux introduced some unexpected regressions. Notably, the kernel build time increased significantly—from less than 3 hours to over 4 hours.
But what concerned me the most was the impact on the performance of xxhash. When built with clang, the xxhash checksum for our btrfs slowed down to just one-third of the speed compared to the version built with gcc. Given that xxhash plays a crucial role in our system’s performance, this was a critical issue.
To address these challenges, I made the decision to rebuild the kernel using gcc instead. The result is our new image, cwt21.1 , which you can find here: Release cwt21.1 · cwt-vf2/archlinux-image-vf2 · GitHub

I seem to be encountering an OPENGL error when running telegram-desktops (AUR). Is it because of my misconfiguration? Or is it that this image does not support the OPENGL driver?

Never tried the telegram desktop client on the VF2. But the opengl stuff on VF2 is far from a working state and completness currently. So that is most probably an issue with that horrible state of opengl on the device.

My NVME install is setup exactly like that…just changing the default line prior to a reboot changes the OS.

Anyone else tried Release cwt22-5.12.0-1 - cwt22 5.12.0-1 and have it fail to recognise the NVME device?/dev/nvme0* or load the root device.
