@jarkko @vbabka It may be good enough for that with some luck. I actually have 9MB 386sx here. Too bad Linux stopped supporting 386 some time ago :-(.

@jarkko @vbabka I feel 4MB is too little for anything other than busybox these days.

@admin @ljs @vbabka For the record, would you mind explaining which part of my comments do you find objectionable? I believe "no regressions" is a long term kernel rule, and while it may be inconvenient to companies, it is existing policy. I'd prefer that rule to stay.

@vbabka I'd really like to see picopad emulation. I tried to hack qemu to do that, but it is a lot of work.

@ljs @vbabka Maybe your employer can fork the kernel if that's so unfair? :-(.

@vbabka Linux on Atari 8-bit was not a joke?

@dcz Aha, and kmscube fails, too, and it has no manpage. GPUs are fun :-(.

@dcz Thank you, that's much better. Is there any special setup to be done?

I'm getting permission denied. Running it as root does not fix stuff.

(Is there easy way to force CPU fallback just to test things)?

@martijnbraam Yep, that seems to be identical problem. Fun thing is unplugging the weird device does not fix the problems...

@dcz Where do I get the bayer binary or its sources? Best I could find is crates/crispy/src/shaders/bayer.rs, and that seems to be something else.

@dcz So far I found that I should be able to build on Droidian on oneplus6, but that has no working camera. I'd really like to play with rggb8 -> rgb888 conversion on the GPU, is that going to be feasible with the current code? (Any hints? :-) )

@martijnbraam Dunno. After plugging it in, desktop fails to react properly to some mouse events. I did not debug it much further, but it basically means you have to log out.

@dcz Ok, so which phone should I play with? I'd like to try libobscura. README says "cargo run --bin glium_2". But I guess "cd libobscura/crates/vidi-examples" is needed before that. And that, on right system. On Librem 5, I get "this version of Cargo is older than the `2021` edition, and only supports `2015` and `2018` editions.".

@martijnbraam I don't believe it even has a mouse part. Its just somehow detected as one. And sw solution is required for this ;-).

I have two devices (train controller and autopilot panel) that are detected as mice in Linux, breaking the desktop when they are plugged in. How to deal with them? Blacklist in kernel? Somewhere in udev

@as400 @alpinelinux Assuming it is accurate :-). It would not be first time battery meters not working properly in edge case.

@ljs Well, what do you believe should be done there? Hong Kong is China, and that can't be fixed. (And yes, communists torture people, Ujgurs, too, probably more). Taiwan is not China, and we can probably make it stay that way. But it is really quite hard to influence country with 1e9 people and nukes. We can't even influence North Korea, 1e7 people and few nukes :-(, and have very hard time influencing Russia, 1e8 people and nukes.
