Pavel MachekAlways fast charging battery to 100% capacity will reduce battery longevity significantly. Complicating factor is that running out of battery is very annoying, and battery below 10% capacity also loses longevity (very significantly around 0%).<br><br>So… we can do better, and this is my attempt. Simple idea is to simply charge to 80%, use “batman norm” to do that.<br><br>But we can do better. You can add time when you want phone to be ready, and it will try to figure optimal charging profile so that phone is at 80% when requested. Use “batman 15:30” if you want phone to be at half past three.<br><br>Code is at <a href="https://github.com/pavelmachek/unicsy_demo/tree/master/bat" rel="nofollow noopener" target="_blank">https://github.com/pavelmachek/unicsy_demo/tree/master/bat</a> .<br><br><a class="hashtag" href="https://social.kernel.org/tag/librem5" rel="nofollow noopener" target="_blank">#librem5</a> <a class="hashtag" href="https://social.kernel.org/tag/linuxphone" rel="nofollow noopener" target="_blank">#linuxphone</a>

Debayering is actually easier and better quality if we downscale at the same time, and that allows best framerate, so we do that (2048x.. resolution).<br><br>ARM has problems with cache coherency w.r.t. DMA, and kernel solution is to simply disable cache on DMAbufs for userspace, which means accessing video data is 10x slower than it should be on the CPU. Which means debayering on GPU is attractive, and that's what we do. (gold.frag). GPU can do more image signal processing functions easily, too, so we do some of that.<br><br>Unfortunately, we hit the same uncached memory problem at the GPU output. So we use separate thread to copy. All this unfortunately does not fit on one core, so we need two threads, one controlling GPU debayer on frame n+1, while the other one copies video data from frame n. (heart.c). We save resulting RGBA data to ramdisk. This all costs maybe 80% of one core.<br><br>From there, Python scripts can pick them up: <a href="http://ucam.py" rel="nofollow noopener" target="_blank">ucam.py</a> displaying the viewfinder and <a href="http://mpegize.py" rel="nofollow noopener" target="_blank">mpegize.py</a> handling the video encoding via gstreamer. There's basically 0% cpu left, but I can encode ~1024x.. video. Unfortunately that's without audio and with viewfinder at 1fps. Plus, combination of C + Python is great for prototyping, but may not be that great for performance.<br><br>Code is here: <a href="https://gitlab.com/tui/tui/-/tree/master/icam?ref_type=heads" rel="nofollow noopener" target="_blank">https://gitlab.com/tui/tui/-/tree/master/icam?ref_type=heads</a> .<br><br>At this point I'd like viewfinder functionality merged into the rest of GPU processing. Ideally, I'd like to have a bitmap with GUI elements, combine it with scaled RGBA data, and rendering it to screen. I know SDL and Gtk, SDL looked like better match, but I could not get SDL and GPU debayering to work in single process (template SDL code is here <a href="https://gitlab.com/tui/debayer-gpu/-/blob/master/sdl/main.c?ref_type=heads" rel="nofollow noopener" target="_blank">https://gitlab.com/tui/debayer-gpu/-/blob/master/sdl/main.c?ref_type=heads</a> ).<br><br>If you can integrate main.c and heart.c, that would be welcome. If you have example code that combines SDL with processing on GPU, that would be nice, too. If you know someone who can do GPU/SDL, boost would not be bad, I guess.<br><br><span class="h-card"><a class="u-url mention" href="https://chaos.social/@datenwolf" rel="nofollow noopener" target="_blank">@<span>datenwolf</span></a></span><br><span class="h-card"><a class="u-url mention" href="https://mastodon.social/@NekoCWD" rel="nofollow noopener" target="_blank">@<span>NekoCWD</span></a></span><br><span class="h-card"><a class="u-url mention" href="https://fosstodon.org/@dcz" rel="nofollow noopener" target="_blank">@<span>dcz</span></a></span><br><span class="h-card"><a class="u-url mention" href="https://fosstodon.org/@martijnbraam" rel="nofollow noopener" target="_blank">@<span>martijnbraam</span></a></span>
