Christian Gmeiner<p>Funny… I'm investigating some wide_line CTS failures, and for some unknown reason, the blob driver does a second draw with line width 1 after the normal wide line draw. etnaviv does not know about the existence/need of this special draw, which causes the CTS tests to fail.</p><p>Starting to question my life choices 🙃 </p><p><a href="https://fosstodon.org/tags/etnaviv" class="mention hashtag" rel="tag">#<span>etnaviv</span></a> <a href="https://fosstodon.org/tags/mesa3d" class="mention hashtag" rel="tag">#<span>mesa3d</span></a> <a href="https://fosstodon.org/tags/librem5" class="mention hashtag" rel="tag">#<span>librem5</span></a> <a href="https://fosstodon.org/tags/mntreform" class="mention hashtag" rel="tag">#<span>mntreform</span></a></p>

Eternal, Majesty<p>Any here with a <a href="https://toot.cat/tags/Librem5" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Librem5</span></a> get terrible WiFi reception with their device? A Purism rep suggested it might be something with my router config. I've now tested with about 5 different routers in and out of my control, and see the same thing with all: I basically need line-of-sight to the router to maintain signal, 5G networks can sometimes do slightly better, maintaining a signal through a single interior sheetrock wall. Other devices, even much older devices, seem to hold connections on these networks just fine. Recommendations?</p>

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>
