ISP on GPU is probably doable. If I'm lucky, it will do ~1Mpix / 30fps on Librem 5. #linuxphone Standby.

@martijnbraam Yeah, robot was suggesting PBOs. It would be great if someone with GPU experience could chime in, ideally saying "no, Librem 5 GPU can't handle 30MB/sec data flow" or better "yes, Librem 5 GPU can handle that easily, here is how" :-). Or maybe "No, can't work on Librem 5, but OnePlus 6 with this example ..."

Anyway, if someone has GPU experience, please chime in. If you know someone, you can show them the post or maybe boost :-).

debayer-gpu (git@gitlab.com:tui/debayer-gpu.git) tries to do debayering on GPU. But it seems OpenGL 2.1 is ... really not meant to do the computation. glReadPixels() can be used to get data off the GPU, but that does not have great performance. On PinePhone, you can only get RGBA out, but we really need RGB. Doing RGBA->RGB on CPU is easy, but it degrades performance further. I believe problem is that ISP produces a lot of data.

On Thinkpad X220, converting 400 images is like 12 seconds. If I do no processing in the fragment shader, it is still 10 seconds. X220 is able to process ~20Mpix/second on GPU. I don't believe Librem 5 will be significantly better.

If you believe GPU can be useful for task like debayering (mostly rearranging data with some additions and 2 matrix multiplies per pixel), let me know. 30Mpix/second on Librem 5 would be useful performance. #linuxphone

The https://liberux.net/ looks so cool. I really hope they're able to deliver, even if I'm not fully in the market for a new phone yet.

Peter from the LINux on MOBile blog did an email interview with them, featuring many of the same questions in my head about this new contender in the space.

So, there's this new "totally unique" Linux phone from Europe that promises to revolutionize something or other. 🙄 In the most #groundbreaking development since sliced bread, they reveal—wait for it—hardware! 🤔 Because clearly, putting Linux on a phone is a feat that no one else has ever attempted before.🥱

Liberux Nexx: An interview with Liberux about their made-in-EU OSHW Linux Phone

As much as I like the existing Linux phones, and am hopeful for the @Liberux, I'm kinda miffed that there isn't a good Linux phone in the general form factor of a #BlackBerry Leap, the all-time greatest smartphone form factor.

Like, give me some venture capital and I'd be up in that shit. I'd give it awesome specs, and have a tailored version of #Slackware with #Phosh on it. Maybe even #NetBSD for shits and giggles.

Does anyone daily drive #postmarketOS or any similar #linuxphone that is not an AOSP derivative?

How’s the experience?

Calling all analog film photographers! 🎞️ I've been working on Filmbook, an open-source app to help you keep track of your film usage. It's built with Rust & GTK4/libadwaita for a smooth & modern experience – and it even runs on Linux phones like the Librem 5 and Pinephone Pro! 📱

The first version is ready for testing, and I'd love your input on what features would make it even better! Join the community & help shape Filmbook: https://codeberg.org/bjawebos/filmbook ✨ #filmphotography #analogphotography #rustlang #gtk #opensource #community #testing #featureideas #librem5 #pinephone #linuxphone

So, after about a month of slow and gradual changes to my phone ecosystem (and after accepting the quite unfortunate limitation of having to rely on my work phone for the national eID in Sweden: "BankID", due to missing NFC): I'm now ready to try out the actual switch from iPhone to #sailfishos #linuxPhone from #jolla as my 'main driver' phone.

Let's see how it goes! 😄

OK, I can understand that this is a niche market and that there won't be as many sales for a #LinuxPhone as for an Android/IOS ... but €1,300 (minimum) for the first backers for the #LiberuxNEXX !? 🤯
