Can you program GPUs and do you want to become a HERO? #linuxphone community needs your help.
We are trying record video, and have most pieces working, but one is missing: fast enough debayering. That means about 23MB/sec on #librem5.
Debayering is not hard; camera images have subpixels split on two lines, which need to be corrected. They also use different color representation, but that's fixable by some table lookup and two matrix multiplies.
Librem 5 has Vivante GPU, 4 in-order CPU cores and 3GB RAM. My feeling is that it should be fast enough for that. If task is for some reason impossible, that would be good to know, too.
Image data looks like this
RGRGRG... xBxBxB... ......... .........
Task is to turn that into usual rgbrgb.... format. rgb = RGB * color matrix, with table lookups for better quality. I can fix that once I get an example.
I'm looking for example code (#pinephone would work, too), reasons it can not be done... and boosts if you have friends that can program GPUs. #gpu #opensource
Since I assume you're going to want to pass the rendered image into some kind of video encoder, you may want to make sure that you match stride and alignment requirements with your target buffer so etnaviv will be able to perform linear rendering rather than de-tile it afterwards (though IIRC it's currently gated behind ETNA_MESA_DEBUG).
@dos adding to that, what data type is the image data (float, int, ???) and what data type is expected to come out?
instead of trying to outsource to the GPU, have you considered SIMD? (I assume librem5 and pinephone support NEON)
if the GPU is better suited, another question is whether there's support for compute shaders on the respective GPUs (what is the supported OpenGL version, assuming there is no Vulkan support on these devices)
@dos As for copies... Yes, I'm currently doing more copies than needed. I measured Librem 5 at about 2GB/sec memory bandwidth, and stream is about 30MB/sec. At 1Mpix/24fps resolution, gstreamer should be able to encode it in real time.
Here's huge problem with v4l, which gives uncached memory buffers to userspace. That means one whole CPU core is dedicated to copying that to "normal" memory. If that is ever solved, yes, other optimalizations are possible. Currently, this means it is not even possible to copy anything bigger than 1Mpix out of the v4l.
Megapixels is not an example of how to do things in the most performant way 😀 OpenGL operates in a VRAM-centric model, it's very copy-heavy. We don't need to copy things around, as our GPUs operate on the exact same memory CPUs do.
Not only you had copies in- and out- of GLES context there, but these copies were sequential - and your benchmark waited until things were copied before proceeding with the next frame, so it was pretty much useless in assessing GPU performance. In practice, GStreamer can happily encode the previous frame while the GPU is busy with the current one, all while CSI controller is already receiving the next one.
@dos Thanks for a patch. And yes, it makes the loop faster.. if you don't actually use the data. When used for loading/saving 720 images from the ramdisk, speed went from ~16 sec to ~21 sec.
I left the memcpy line commented out for a reason - with it uncommented, the result is exactly the same as with glReadPixels (which is effectively a memcpy on steroids). The point is to pass that buffer to the encoder directly, so it can read the data straight from the output buffer without waiting for memcpy to conclude.
I've also verified that the approach is sound by having the shader output different values each frame and accessing it via hexdump_pixels inside the loop. Still fast ;)
That said, rendering to a linear buffer can be slower, that's expected. The question is whether gains from passing buffers around for free are higher, which for an actual "record video from a camera" use case will almost certainly be true (and which has very different performance characteristics from reading images from files - you can't directly attach a file as a texture).
Yes, with memcpy(), I'm getting same results as before. If I get rid of the memcpy(), and attempt to fwrite() the buffer directly, things actually slow down.
I can't easily connect gstreamer to that, I'm going through ramdisk for now. I'm using time ./ocam.py debayer for testing -- gitlab.com/tui/tui/-/blob/mast…
Why not? I quickly hacked up passing dma-bufs to GStreamer and even though I'm glFinishing and busy-waiting on a frame to get encoded sequentially it still manages to encode a 526x390 h264 stream in real time on L5.
Plugged it into V4L2 - with a caveat that for now I fed the GPU full-res 13MP frames to meet stride alignment requirement (the shader output is still 526x390). It says it does 240 frames in 10.55s. I wonder if it's really slightly too slow, or just bad timing from our camera stack 😀
It's ugly, hardcodes everything, lies on frame timing, occasionally segfaults. Most of it is copied straight from LLM, I just massaged the pieces to work together. Not the kind of code I'd like to sign off on 😀 But it's a working example, so have fun with it.
The first thing to do to improve it (after cleaning it up) would be to actually make use of the buffer pool. Dequeue the buffer, attach it as a texture, kick off rendering, get a fence and pass it with the output buffer to GStreamer without waiting on rendering to finish, then queue it back asynchronously once rendering is done. This should allow for much more complex shaders than this sequential code does.
BTW. The fact that I could stream full-res frames and bin them down in the shader at real time is an interesting news, as this may open up possibility to use phase detection autofocus.
@dos Exactly. That's a bit of big deal. That's why I'm trying to make sure this code does not go away. I had phase-detection auto-focus working at one point, but decided it is unusable as I did not see a way to scale down images quickly enough.
There's a question whether it will be worth elevated power consumption though. I've also stumbled upon csi erroring out with "Rx fifo overflow" requiring a reboot to recover that I haven't seen at lower resolutions, but haven't looked closer.
@dos Yes, there's more work to be done in the kernel; sometimes camera does not work after reboot, bayer-10 modes are not supported, ... 🙁. And yes, it will take more power, but with phase-detection AF, it should be significantly better camera.
@dos Fences; that must be some kind of dark magic.
This code seems too good to be true. So, just to be sure, and in case you disappear tomorrow, can I add /* Copyright 2025 Sebastian Krzyszkowiak, GPLv2 */ and act according to that?
Good question. Not sure what license would be appropriate to put on something that's mostly an output of a model trained on code on all sorts of licenses anyway...
But given that it's just a bit of glue code between three APIs put together as an example, consider it to be under MIT-0 😜
When I lie to GStreamer and tell it that its input is in YUY2, it gets faster - perhaps even fast enough to encode at 1052x780. That's another opportunity for improvement.
(and there's nothing magic about fences, it's just a simple synchronization primitive 😛)
@dos Yeah, I played a bit. Nice. But segfaults, occasionaly, and may segfault more when I switch to matroskamux. So I guess crash may be gstreamer-related? 😀. There's also some kind of noise in bottom right corner, maybe that's related, too.
I'm playing with GStreamer now (which is new for me) and it seems like most of this code could be replaced with GStreamer elements, and the rest should neatly plug in as custom elements 😂
You've got a dma-buf handle, already mapped buffer and even GStreamer with all its sinks available, so... however you want? Pretty much anything will be able to consume it easily.
@dos I don't have much experiences with GUI programming, so I was looking for suggestions. I've got dma-buf handle but would not know what to do with it in gtk, and maybe SDL is better match. Or perhaps stick to original plan and do user interface ("take picture" button etc) in another process.
Not sure what you mean. GStreamer is internally multi-threaded, but its API is thread-safe and there's only one thread in this code. Of course any kind of production-quality code will use some mainloop and enqueue buffers based on callbacks rather than while(!processed){} loop, but it's not exactly rocket science.
@dos There are at least two threads in this code: main one, and whatever runs "on_buffer_released". I don't yet know what causes the segfaults, but I suspect gstreamer.
@dos Lets keep the example simple 😀. Yes, g = G1+G2/2 is superior, and there are advanced debayer algorithms. I know them. Examples are at gitlab.com/tui/debayer-gpu/ . There's just one small problem: It takes minute and I need it to take 10 seconds.
@dos It seems that ignoring half of green pixels is right thing to do at the moment: gitlab.com/tui/debayer-gpu/-/t… "Normal" debayer is 40% too slow. (That's better than 5 times too slow, but still not good enough). If you can can get it to 24 loops in second, you'll become a hero 😀.
On 9f076a5, I'm getting 88MB/s with one green channel, 82MB/s with two and 105MB/s with nothing but static gl_FragColor. The three copies it does could be eliminated and I believe texelFetch could make it slightly faster on the GPU side too.
Anything that works on Librem 5 is fine, bonus points if I can understand it. Robot generated code using -lEGL -lGLESv2 -lm ... and that builds and does something. Librem 5 reports:
Vendor: etnaviv Renderer: Vivante GC7000 rev 6214 OpenGL Version: OpenGL ES 2.0 Mesa 21.2.6 GLSL Version: OpenGL ES GLSL ES 1.0.16
are you limited to OpenGL ES 2.0 or can you use a more modern version? ES-2.0 is very bare bones in its image format and shader capabilities and efficiently converting 10 bpp will be a PITA, due to lack of texelFetch function. Anyway, spent the day finding a nice polynomial to linearize the sensor values (LUTs should be avoided if possible, memory access has latency and costs energy, if you can calculate in a few instr. prefer that).
@datenwolf I believe I'm limited to OpenGL ES 2.0. Presumably hardware can do more but our current drivers can not, so we are stuck there.
On the other hand... #librem5 main sensor can not do 10bpp at the moment, due to missing drivers. So maybe we can focus on 8bpp, first. Probably ineffecient conversion is "good enough" too, as GPU is a bit overpowered for this job.

Dans l'un de mes derniers posts je vous faisais part de mon étonnement et de ma colère au sujet du criminel #BillGates reçu comme un chef d'Etat par les gouvernements occidentaux corrompus. En effet, comment justifier qu'un type qui veut réduire la population mondiale de 10 à 15% avec ses faux #vaccins, ne soit toujours pas en prison ? Comment comprendre que ces gouvernements collaborent avec des labos pharmaceutiques multi-condamnés pour tromperie, pour mise en danger de la vie d'autrui, pour homicides "involontaires", pour empoisonnement et autres délits ? Il n'y a qu'une seule réponse possible. L'industrie pharmaceutique dont la puissance financière dépasse de loin l'industrie de l'armement, est l'un des plus grands corrupteurs que le monde ait connu. Si donc nos gouvernements collaborent avec cette industrie de la mort, au détriment de leurs propres peuples, c'est qu'ils sont corrompus jusqu'à l'os. Quel imbécile peut encore leur faire confiance ?
#RFKJr frappe fort : les #États-Unis gèlent tous les financements à #GAVI, l’Alliance vaccinale cofondée par #BillGates. Motif ? 🔍 Le #DTC, vaccin massivement injecté en Afrique, tue plus d’enfants qu’il n’en sauve. Étude validée, preuves accablantes. #GAVI le savait. Ils ont continué. Pas de sécurité. Pas de transparence. Juste une industrie qui sacrifie des vies au nom de l’idéologie eschatologique et du profit. Fin de la récré pour #BigPharma. L’impunité a une date de péremption. #RFKJ est trop gentil. Ces gens devraient tous être jugés par des tribunaux populaires... E. Montana
But not everyone is applauding the decision. Bill Gates, the tech mogul turned vaccine evangelist whose foundation has bankrolled Gavi from the beginning, is ringing alarm bells. In a Gates Notes blog post, he claimed: "There's never been a point in the past 25 years when more lives hung in the balance. In all likelihood, 2025 will be the first year since the turn of the century when the number of children dying will go up instead of down."
Gates and the European Union responded to the funding gap with a major fundraising push. This week, they co-hosted the "Global Summit: Health & Prosperity through Immunization" in Brussels, trying to save the alliance from financial freefall. Gavi's CEO, Sania #Nishtar, claims that the U.S. cut alone could result in an additional 1.2 million deaths over the next five years.
Despite those claims, the summit raised over $9 billion toward Gavi's $11.9 billion goal for its 2026–2030 budget. The Gates Foundation pledged $1.6 billion. The European Commission threw in €260 million. An additional $4.5 billion was committed from development finance institutions, and vaccine manufacturers chipped in with cost-cutting agreements expected to save another $200 million.
'When the science was inconvenient, Gavi ignored the science,' stated Health Secretary Robert Kennedy Jr. when announcing plans to halt funds to Gavi in an effort to restore public safety and trust.
The official narrative is or maybe was that you can not change one element into another except by a nuclear reaction
So you would be doing a chemical reaction on something that already has oxygen in it's chemical formula to end up with oxygen in the O2 form without other elements chemically binded to O2
But I also presume Mars is a light in the sky and they do not have real footage of it's surface and the Mars rover images or videos are fake
You obviously don't have a scientific background and do not understand what was technically possible, in the 1960s.
I actually watched the moon landing and I was super interested in high tech. I watched the emergence of hard- and software.
It was materially IMPOSSIBLE to record videos of more than 30 seconds, back then, so it all had to be live-streamed.
There was no CGI. There was no "photoshop". The largest working memory on a mainframe was 8 MB.
They brought back fantastic photos in extremely high resolution from a Hasselblad camera - from space and the moon's surface.
NVidia demonstrated that it was IMPOSSIBLE to get the lighting right without a full ray tracing simulation, which they could not have performed, back then. Everything on those images is EXACTLY as it would have to be if they actually were on the moon & could not have been simulated.

A new report from the Center for Media Monitoring has laid bare the biases in #BBC reporting of Israel’s war on Gaza. Among the key findings from the study, which analyzed an incredible 35,000 pieces of BBC news content (articles, interviews, #TV clips, etc.) were:
Israeli casualties received 33 times the coverage as Palestinian ones. Emotive words like “murder” or “massacre” were frequently used to describe Israeli deaths, but rarely Palestinian ones.
The BBC interviewed twice as many Israeli guests as Palestinians, and were 11 times as likely to give viewers the Israeli perspective.
On more than 100 occasions, BBC anchors tried to shut down guests claiming that Israel was carrying out a genocide.
The BBC, of course, is not a neutral actor, but a one-sided, pro-Israel organization. Its online Middle East editor, is, by his own admission, a former #CIA employee and #Mossad “collaborator.” For more on that story, see the investigation:
Raffi Berg, now at the center of a media scandal over the BBC’s Israel coverage, once worked for a known CIA front and collaborated with Mossad officials.
@israel, it is called genocide in Spanish public media and even in the parliament, I can't understand why it can't be called this way in the BBC. Fucking Right Wings and their media
because the UK is taking active part in the genocide, not only by subsidizing Israel and its military, they are flying spy planes off Cyprus for the IOF. Calling it a genocide would imply that the UK can't keep its support for Israel.
The UK created this whole mess with the Balfour Declaration in the 1920s. The United Kingdom is single-handedly responsible for every Palestinian death since they, alone, created the situation that led to the Nakba.
@gme @Catweazle I wouldn't say "single-handedly" responsible, since the USA and Germany took a very big part in creating the current situation, but indeed you are correct. You could also say that many of the problems in Syria, Iraq, Iran, are due to the British Empire meddling in the region.
#Germany summons Iranian ambassador over alleged spying on Jews 🤨 … it’s Germany’s turn to carry out some dirty work for Israel it seems.. but what about summoning the Israeli ambassador over the documented ongoing genocide in #Gaza?
As part of the “new chapter” in its history, #Germany has become a kind of #Jewish shtetl. Descendants of #Nazis adopt Jewish symbols, worship #Zionism and persecute Jews who criticize Israel – in the name of fighting #antisemitism, of course.
Hefetz describes how Germany has undergone what she calls “convertion to Zionism,” that is the transformion of descendants of Nazis into “the new Jews.” But she starts with a joke she heard from a Jewish child in #Berlin:
“What’s the difference between Jews and Muslims? The Jews are already past that.”
Muslims have become the new target for traditional German racism and intolerance. She contrasts today’s Germany with the country she found 23 years ago:
“Germany 23 years ago was truly a different Germany. It was still an anti-militaristic and anti-nationalist society and state, which respected its constitution and international law to some extent, where a million people marched against the horrific and internationally illegal war by the US in Iraq, which Germany refused to participate in.”
She traces this transformation back to Germany’s first chancellor, Konrad Adenauer, who stated: “We caused the Jews such great injustice, we committed such terrible crimes against them, that there was a need to atone for them or repair them to some extent, if we wanted to regain honor among the nations of the world.” However, Adenauer’s antisemitic reasoning was revealed when he added: “The power of the Jews – even today, especially in America – should not be underestimated. Therefore, I consciously and carefully invested my entire being, to the best of my ability, to bring about reconciliation between the German people and the Jewish people.”
Hefetz says that Germans have now collectively “converted to Zionism” without the need for actual conversion:
“An entire wing of the German ‘left’ consists of men who ‘engaged in identity searching’ and found it in the form of Israel. They sound as if Noa Tishby is speaking from their throats, wrapping themselves in Israeli flags and IDF flags, going to see folk dance performances celebrating diplomatic relations between the states, and saving Jews from ‘antisemitism.’”
She explains that “according to data published in the Israeli magazine in Berlin, ‘Spitz,’ in an article later removed, more than half of the complaints about antisemitic incidents in Germany are by German Christians with Nazi grandparents, who are attacked by Jews demonstrating against Israel, for example.” The irony, she notes, is that “descendants and great-grandchildren of Nazis are very sensitive to ‘antisemitic attacks against them,’ especially if they come from Jews and Israelis.”
Hefetz describes Germany’s creation of an artificial Jewish identity: “Germany has become a kind of Jewish shtetl. There is no place in the world where you can hear more #klezmer music (traditional Eastern European Jewish music) , adapted to the German ear. The popular names in recent decades in Germany are Hebrew Jewish names.” She explains how “the German state began funding Reform conversion of Christians to Judaism, and recreated the destroyed German liberal Judaism, a ‘new Judaism’ that is of course more desirable than the ultra-Orthodox, who are ‘Ostjuden.’”
Note: The original derogatory term #Mizrahim as used by Ashkenazi Jews, referred to Jews of Eastern European heritage. In #Israel this term was then repurposed to describe Arab Jews, mostly, as part of what Aziza Khazzoom described as de-orinetalization of the largest Jewish diaspora, see “How the Polish Peddler Became a German Intellectual” sup.org/books/sociology/shifti…
Hefetz details how this “Israelization” serves #Germany’s return to #militarism:
“Identification with Israel helps Germany return to being a militaristic state: it helps break the taboo of nationalism; it helps rehabilitate the image of the German man, who in the years after the war tried to be ‘non-German’ by emphasizing soft qualities, non-authoritarian education for children.”
She quotes recent statements by German Chancellor Friedrich Merz, who said Israel “does the dirty work for us” regarding attacks on Iran, while a security expert from his party stated “we are also ready to die for Israel.” She notes the antisemitic nature of these statements:
“These antisemitic statements about Jews doing Germany’s ‘dirty work’ are not new, and the reference to killing civilians as ‘dirty work’ recalls Himmler’s Poznan speech, or what Rudolf Hess said at the Nuremberg trials.”
She concludes that “Germany is making a comeback” through authoritarian measures disguised as fighting antisemitism, while “Germany supplies Israel with at least a third of the weapons for the genocide in Gaza.” Despite this official support, Hefetz notes that “there is an absolute majority in the German public that consistently opposes supplying weapons to Israel; and with all the pro-Israeli propaganda and Israeli flags flying over every government office in Germany, 73% think what Israel is doing in Gaza is genocide.“

Ohmies. I have been trying to explain the Repo market chaos and the relationship to Covid since the very beginning--it was one of the main signals that lead me to believe that Covid was fake. I am not an investor, but I have been watching the markets since 2008, when I became convinced that the debt supernova was THE driving force behind all happenings.
I was convinced my thinking was correct, so in 2008 I left L.A. (and my marriage) because once I saw that the debt bubble was being successfully re-inflated, I knew that it would return with a vengeance, and that the Government would need an EXCUSE for the next even more massive bailout. A second naked "bank bailout" would not fly with the masses was my logic. Some kind of false flag would be necessary. I wanted to be out in the rural area to build a buffer against whatever false flag the diabolical traitors had in mind. I figured 10 years MAX to get prepared.
I was slightly off. It was 11 years.
In 2019, the Repo Market (short-term, interbank lending market) was screaming that the whole banking system was on the verge of collapse--SOMETHING absolutely had to happen.
Covid was the thing that checked the most boxes--the thing that could align the incentives of the string-pullers.
It took the genius of Brett Weinstein to convince me that there really was a virus. I didn't believe the virus was real until I fell under the Twatter / Rogan / Weinstein spell (much to my current embarrassment).

Bu karanlık kalple mücadele etmek için Hıristiyanlık Tanrı'ya teslim olmayı; Mill insanlıkla birlik duygusu geliştirmeyi; Kant ahlakın gereklerini en önemli önceliğimiz haline getirmeyi; Singer kendini acıyı azaltmaya adamayı; ben ise Platoncu bir arayışla insanları erdemli kılmanın güvenilir bir yolunu bulmak için bilimi kullanmayı öneriyorum. Bunların hepsi ortak bir mücadelenin biçimleridir - insan doğasında var olan bencilliğe karşı mücadele. Belki de bu mücadele hepimizin aynı tarafta olduğu bir mücadeledir. Yaşasın etik devrim."
@Max_Imum i planted a Pinot noir vine from Lowes a few years back. Last year I had enough grapes to make two cups of grape juice (and ate a bunch and so did the birds)
I trimmed it back in the fall.
For some reason, maybe because I don't know how to properly/effectively grow stuff, I was SHOCKED by the vine's growth again this year. I had to trim it back because it is going nuts.
I didn't do anything to it except try to train it to the trellis. Nature is amazing.
If they hope this will get men want to marry again, i don't know if it'll work out as they expect it to. Not after men can learn about the true nature of women and the pitfalls of marriage on social media. But it's certainly a sensible start to restore some much needed balance in the relation of the sexes.
Unfortunately, we won't ever see something like this in the West as long as the current liberal-democratic-progressive-vaginal paradigm persists.

Additionally, Medicaid, Medicare, and Social Security Benefits are not being cut, but are being STRENGTHENED and PROTECTED from the Radical and Destructive Democrats by eliminating Waste, Fraud, and Abuse from those Programs.
We can have all of this right now, but only if the House GOP UNITES, ignores its occasional “GRANDSTANDERS” (You know who you are!), and does the right thing, which is sending this Bill to my desk. We are on schedule — Let’s keep it going, and be done before you and your family go on a July 4thvacation. The American People need and deserve it. They sent us here to, GET IT DONE!
Our Country is going to explode with Massive Growth, even more than it already has since I was Re-Elected. Between the Growth, this Bill, our Tariffs, and more, “THE ONE, BIG, BEAUTIFUL BILL” sets the United States down a fiscal path by greatly reducing our Federal Deficit, and setting us on course for enormous Prosperity in the new and wonderful Golden Age of America.
To my GOP friends in the House: Stay UNITED, have fun, and Vote “YAY.” GOD BLESS YOU ALL!

You lose meaningful data if you ignore half of green pixels.
I see no reason why it couldn't be done. Just take care not to introduce needless copies in your processing path. dmabufs are your friends.

adding to that, what data type is the image data (float, int, ???) and what data type is expected to come out?
instead of trying to outsource to the GPU, have you considered SIMD? (I assume librem5 and pinephone support NEON)
if the GPU is better suited, another question is whether there's support for compute shaders on the respective GPUs (what is the supported OpenGL version, assuming there is no Vulkan support on these devices)
Sebastian Krzyszkowiak
in reply to tizilogic • • •@tizilogic It's either 8-bit int, or 10-bit int stored as 16-bit.
GC7000L supports compute shaders, but etnaviv isn't there yet.
Naive debayering is easy, but for good picture quality you need much more than that.
Pavel Machek
in reply to Sebastian Krzyszkowiak • • •@dos As for copies... Yes, I'm currently doing more copies than needed. I measured Librem 5 at about 2GB/sec memory bandwidth, and stream is about 30MB/sec. At 1Mpix/24fps resolution, gstreamer should be able to encode it in real time.
Here's huge problem with v4l, which gives uncached memory buffers to userspace. That means one whole CPU core is dedicated to copying that to "normal" memory. If that is ever solved, yes, other optimalizations are possible. Currently, this means it is not even possible to copy anything bigger than 1Mpix out of the v4l.

in reply to Pavel Machek • • •Megapixels is not an example of how to do things in the most performant way 😀 OpenGL operates in a VRAM-centric model, it's very copy-heavy. We don't need to copy things around, as our GPUs operate on the exact same memory CPUs do.

in reply to Pavel Machek • • •After eliminating glReadPixels and having the output buffer mmaped instead: "18.9 MB in 0.08s = 244.4 MB/s"
After putting glTexImage2D out of the loop to emulate zero-copy import from V4L as well:
"18.9 MB in 0.05s = 400.1 MB/s"

in reply to Sebastian Krzyszkowiak • • •Also, it gets faster when you increase the buffer size, because rendering is so fast you're mostly measuring API overhead 😁
With full 13MP frames: 315.1 MB in 0.62s = 511.3 MB/s

in reply to Pavel Machek • • •I left the memcpy line commented out for a reason - with it uncommented, the result is exactly the same as with glReadPixels (which is effectively a memcpy on steroids). The point is to pass that buffer to the encoder directly, so it can read the data straight from the output buffer without waiting for memcpy to conclude.
I've also verified that the approach is sound by having the shader output different values each frame and accessing it via hexdump_pixels inside the loop. Still fast ;)
Sebastian Krzyszkowiak
in reply to Sebastian Krzyszkowiak • • •Pavel Machek
in reply to Sebastian Krzyszkowiak • • •@dos But you only hexdumped first few pixels, right?
Is that buffer uncached or something?
I pushed current code to gitlab.com/tui/debayer-gpu .
Yes, with memcpy(), I'm getting same results as before. If I get rid of the memcpy(), and attempt to fwrite() the buffer directly, things actually slow down.
I can't easily connect gstreamer to that, I'm going through ramdisk for now. I'm using time ./ocam.py debayer for testing -- gitlab.com/tui/tui/-/blob/mast…

Why not? I quickly hacked up passing dma-bufs to GStreamer and even though I'm glFinishing and busy-waiting on a frame to get encoded sequentially it still manages to encode a 526x390 h264 stream in real time on L5.

It's ugly, hardcodes everything, lies on frame timing, occasionally segfaults. Most of it is copied straight from LLM, I just massaged the pieces to work together. Not the kind of code I'd like to sign off on 😀 But it's a working example, so have fun with it.

Plus it also adds possibility of zooming.

IIRC PDAF was also usable at half-res.
RAW10 is just a matter of setting up clocks for higher bandwidth and more lanes. Switching data format is then just a single register away.
Pavel Machek

This code seems too good to be true. So, just to be sure, and in case you disappear tomorrow, can I add /* Copyright 2025 Sebastian Krzyszkowiak, GPLv2 */ and act according to that?
Sebastian Krzyszkowiak
in reply to Pavel Machek • • •Good question. Not sure what license would be appropriate to put on something that's mostly an output of a model trained on code on all sorts of licenses anyway...
But given that it's just a bit of glue code between three APIs put together as an example, consider it to be under MIT-0 😜

Do I guess correctly that shaders can do arbitrary resolutions, such as 800x600?
I like the v4l+shaders integration. I'm not sure if I like the v4l+shaders+gstreamer integration.

For SDL with GL: just import it the same way V4L buffers are imported.
Frankly, it's flexible enough that your choice of toolkit should only depend on other factors.

in reply to Pavel Machek • • •Anyway, spent the day finding a nice polynomial to linearize the sensor values (LUTs should be avoided if possible, memory access has latency and costs energy, if you can calculate in a few instr. prefer that).
Pavel Machek
in reply to datenwolf • • •@datenwolf I believe I'm limited to OpenGL ES 2.0. Presumably hardware can do more but our current drivers can not, so we are stuck there.
On the other hand... #librem5 main sensor can not do 10bpp at the moment, due to missing drivers. So maybe we can focus on 8bpp, first. Probably ineffecient conversion is "good enough" too, as GPU is a bit overpowered for this job.
