Also, it looks like NXP has picked up their Cadence HDMI/DP bridge/PHY driver upstreaming effort again, which is a great news as it's one of the biggest things we carry in the downstream #librem5 tree! https://lore.kernel.org/lkml/20260407-dcss-hdmi-upstreaming-v21-0-4681070ab82f@oss.nxp.com/T/

I think he's enjoying his win. #cats #cat #caturday #catsofmastodon #shotonlibrem5

Yup, and we have a winner it seems! Congrats, Mostly White Guest! #cats #caturday #catsofmastodon #shotonlibrem5

I think it may be slowly turning into a napping contest #cats #caturday #catsofmastodon #shotonlibrem5

Here's a before-and-after example. There's much more (done with an early version of this code) in my old thread: https://social.librem.one/@dos/115091388610379313

Millipixels has really overstayed its welcome, it was meant to be a temporary pile of hacks to facilitate driver development, but - perhaps inevitably, as makeshift does - it stayed there much longer than anticipated. I have spent a few hours polishing some of its roughest edges, finishing up past WIP work and hacking some desperately needed quality-of-life improvements in. Along with e.g. rotation sensing and better QR code detection, it can now also adjust frame rate to extend exposure time.

Last but not least, last kernel update is also lowering the FPS you can get in various modes - from 120/60/60/20/15 to 83.3/40/30/20/8. Why? It was the easiest way to reduce the MIPI CSI-2 clock freq, which turns out to effectively resolve the issue of camera locking up until a reboot under DRAM load due to ERR050384 erratum! The driver could be made to configure the clocks dynamically to unlock the full FPS range again, but that's left for later. Kernels are hard to show, so have more cats 😸

Here's a few cat-less examples too for some variety. The processing is still pretty basic, you can easily get better results out of Darktable etc. but it should nevertheless be a big improvement for what you get by a simple point-and-shoot.

@codo@fosstodon.org @janvlug@mastodon.social You can easily turn any website into a webapp, whether it's defined as a PWA or not. Pic related. Battery, in my experience: 4-5 hours of active use; 12-14 hours of idling without sleeping; 22-24 hours in system suspend where it wakes up from calls and SMS. Calls and SMS have been reliable for me here in Poland, but it's always subject to carrier compatibility now with VoLTE. In general there's no need to reboot at all unless updating or working on the kernel.

@sos@mastodon.gamedev.place C++? 😱 What made you add these pluses to the mix?

@opensourceopenmind@social.vivaldi.net @etbe@mastodon.nzoss.nz Depends on your needs. I use XMPP daily, but I definitely wouldn't want it to scream for my attention. It's supposed to show me the messages when I reach for the phone, not the other way around :P

@etbe@mastodon.nzoss.nz @opensourceopenmind@social.vivaldi.net It could be better, but it usually manages to go through a day on a single charge, which is far from the point where I'd personally start considering such measures. Are you using system suspend? If not, why?

@codo@fosstodon.org @janvlug@mastodon.social If you don't care about what's currently on the phone, you can just reflash it: https://docs.puri.sm/Hardware/Librem_5/Maintenance/Reflashing.html If you do, there are ways to mount its filesystem over USB and investigate too.

@Luigi311 The bottleneck for photo taking is actually DNG unpacking and JPEG compression. The shader is able to process more than 30 FPS (although at fairly low resolution), as it was written for real-time video recording: https://source.puri.sm/-/snippets/1223

@janvlug@mastodon.social @codo@fosstodon.org BTW. I do have a plan to make it be dealt with automatically on stock PureOS with minimal negative impact, just bear with me for a while still as unfortunately I only have two hands and one head and need to sleep at times 😁

@janvlug@mastodon.social @codo@fosstodon.org It's a modem firmware bug that we have no control over. There are workarounds with various tradeoffs, you could put a watchdog for it too. In practice, for me it's only a minor annoyance since flipping the switch is so fast, but I can see it being disruptive for certain use cases. Fortunately the modem is easily replaceable so we won't be stuck with this forever.

@jajo@mastodon.nu @janvlug@mastodon.social Here in Poland there is one kind of instant payments that can't be done without my bank's mobile app (Blik) - but their Android app works fine in Waydroid. Some banks around the world require platform attestation which is extremely user hostile though. If your bank is among those, you should complain to them and maybe look for alternatives.

@Sonikku@techhub.social oh no

@wariat@mastodon.social @kokos@mastodon.com.pl @rocking_horse@mastodon.social To co się zmieniło od tego czasu to to, że Rada Języka Polskiego uznała odmianę z zachowaniem x za także dopuszczalną, więc choć "Firefoxie" nadal tak samo kłuje w oczy, to już odpada argument, że jest niezgodne z oficjalną ortografią którym można było kiedyś zamknąć dyskusję. Natomiast postulowanie używania tu apostrofu to kompletna i oczywista odklejka xddd

@rocking_horse@mastodon.social To chyba musisz się lepiej zapoznać z językiem polskim w takim razie.

@newbyte @fisherdude You really want to be on the latest kernel as well!

@Blort Which one do you want to see? It's still using a very basic debayering method of 2x2 superpixels, so it has its dimensions halved and produces false colors at contrasting edges. I'm going to put a better demosaicing algorithm in there, but will have to see how much higher output resolution will influence performance before making it the default.

@aleabdo Already available in crimson-updates-proposed! Migrating to crimson-updates in a week.

@fun @noisytoot @alexanderkjall It is not serious, but OTOH the exploit is simple enough that it's still relatively easy to decipher.

@sos@mastodon.gamedev.place that damned satan's seed!!!

The way it does video recording is still... uhm, not great 🤪 so it's only usable for short clips, but it also benefits from the processing improvements, so these short clips should at least look prettier now. Audio should be a bit less desynced now too. If you want to record for as long as your storage lets you to with perfect audio sync, check out the video recorder at https://source.puri.sm/-/snippets/1223

@zwarf@social.anoxinon.de What exactly do you mean by "not a great experience performance wise"? In my experience while not exactly silky smooth at all times Pure Maps is perfectly usable on the Librem 5.

@wolnoscwkieszeni@mastodon.com.pl @mat_hmm@mastodon.social Co prawda nie używam pmOS, ale moim daily driverem jest Librem 5 z PureOSem już od kilku lat, więc z tym "nie nadawaniem się" bym nie przesadzał. Może się nie nadaje gdy oczekujesz, że wszystko będzie działać na losowym sprzęcie przy którym sobie z nudów dłubie jedna osoba po kilka godzin w miesiącu 😜

@codo@fosstodon.org @janvlug@mastodon.social It's not really brickable unless you physically damage it or lock it down with e-fuses.

@vincent Similar story with fuel gauge patches, they need some changes: https://lore.kernel.org/lkml/20220318001048.20922-1-sebastian.krzyszkowiak@puri.sm/ Generally, aside of really recent stuff, things that stay downstream usually have a reason to stay there. Some reasons are easier to get rid of than others though, so I can help point you in their direction.

@codo@fosstodon.org @janvlug@mastodon.social OK, that's the one (the other string shows up in dmesg, I mixed them up). You should be able to flash it, though if the red LED is shining continuously you may want to give it a few minutes to charge up a bit first, as from the previous messages it seemed like it might have been browning out on power.

@codo@fosstodon.org @janvlug@mastodon.social Keep the battery in, keep it plugged in. Holding the power button for about 5 seconds will turn it off, holding Vol+ while turning it on will put it into flashing mode. Verify it's seen in lsusb as NXP SE Blank M850, then launch the script.

@vincent Yes, feel free to ping me there. Regarding USB there is https://lore.kernel.org/all/20260316-eth-null-deref-v1-1-07005f33be85@google.com/ - in next but hasn't reached stable trees yet, so you may be missing that.

@rocking_horse@mastodon.social @kokos@mastodon.com.pl W sens'ie że wpieprz'amy apostrof'y w niewłaściw'e miejsc'a? Apostrof służy do zasygnalizowania czego nie wymawiać.

@tragivictoria@mastodon.catgirl.cloud Ale to że niby mają wrócić to raczej taki medialny głuchy telefon. Oni wnioski o sloty wysłali jeszcze zanim się wycofali, a wycofali się nagle gdy im sanepid zamknął magazyn 😂

@kokos@mastodon.com.pl Jeszcze nie tak dawno tylko jedna z tych form była poprawna i tak powinno było pozostać.

@tragivictoria@mastodon.catgirl.cloud W sensie te z jesieni? Oni je wtedy w końcu uruchomili, z opóźnieniem bo nie mieli personelu na czas 😜

@vincent Note that there's an upstream lm3560 driver, but it uses V4L2 API. As far as I'm aware the reason for writing a new one was that a LED device can be attached as a V4L2 subdev, while V4L2 device can't be exposed through the LED API, so some discussion with upstream maintainers may be needed first. Also, I don't consider s5k3l6xx driver to be anywhere near upstreamable quality just yet. It needs a solid cleanup and it still has a few open problems to solve in its clock configuration.

@codo@fosstodon.org @janvlug@mastodon.social Not even when holding Vol+?

@vincent Incidentally, I think attempting to apply the feedback from the gauge series would be a good start! It's self-contained and I haven't touched it for a while so we wouldn't step on each other's feet, as I've been reworking some other stuff for mainlining recently too. The TPS65982 stuff is very entangled with other drivers, firmware config etc. so I'd leave that one for later.

@vincent Though we may consider configuring it out-of-spec anyway if it ends up helping with ERR050384.

@zwarf@social.anoxinon.de Test it with "/usr/libexec/geoclue-2.0/demos/where-am-i -t -1 -a 8" If you don't upload fresh assistance data with https://source.puri.sm/-/snippets/1207 it will likely take a few minutes to get a cold fix.

@vincent These events aren't handled in the upstream driver, so I don't think this patch makes sense there without reworking and upstreaming other patches as well. Also, it's already there in the 6.18 tree: https://source.puri.sm/sebastian.krzyszkowiak/linux-next/-/commit/a2b7faa8e47673f18a002f07517e218cbe39b6a1 There's still feedback to apply from https://lore.kernel.org/lkml/20220317154518.4082046-1-sebastian.krzyszkowiak@puri.sm/ that I have never got around to do so far. That's why I asked to coordinate ;)

@codo@fosstodon.org @janvlug@mastodon.social Just hold Vol+ button while turning the phone on, it won't do anything but should then show up in lsusb and then run the flashing script.
