conclusion… whatever the structure of what you are doing, the kernel only deals with a rasterized version of it… a thought: 3 ioctl for something that should be done with… drumrolls… 1 … if the structure passed contained all the data. 🤔 … where did i see something similar… …. right!! got it… it is what was done to vulkan to learn from the inefficiency of opengl. so then… when will drm be modernized??? the funny part is that the atomic part is basically already similar to the vulkan notion of command buffers… … so why not go all the way and also change these 3 ioctls at the start into 1 (and do it everywhere else where applicable)

I think we completely bypassed the gpu and wrote directly into the frame buffer.... I guess this is how it all works: 1a) a program calls opengl to write gpu code (ie, shaders)+vertex info+normal info etc into some buffers in host memory. 1b) these buffers are processed by the graphics card driver and sent into the graphics card memory via PCIe bus. 1c) gpu reads these buffers from the graphics card memory, turns them into pixels, and writes them again into some off-screen buffers in graphics card memory. 2a) OR, a program opens a fbdev buffer and prints pixels directly into it. 2b) these fbdev pixels is written into some off-screen buffers in graphics card memory. 3) This way, if many programs work in host cpu, they will generate many off-screen buffers in graphics card memory. 4) It is the task of a compositor, like wayland/weston, to take all these buffers, composit them, and generate a single frame buffer, which will be displayed. In my opinion, this presentation follows the road 2ab-3-4. It would be very interesting to watch a program which would follow 1abc-3-4. I curse the event organizers to cut this program that short. I hope mr ser does a fırther program in which he shows us kms+opengl integration...

Really useful and informative!

:)

Well explained thanks Julian.

Camera is too far away to read slides.

Background sound is annoying and makes it tough to follow speaker.

Very helpful, thanks!

Very informative talk! 🎉

Let's just build the visually inspectable technology with 90s equivalent performance, and go from there. If you build it, they will come.

So, the hardware problem is a complete unsolved monster?

How does this all relate to the /dev/fb0 I can write to today

Great presentation! I wish I would saw it earlier. Thanks!

Sir can I use GFDL images from wikimedia commons in my KZfaq please please please give reply

I wrote a version of Unix for my atari ste in a combination of assembler and cross-compiled C back about 1990(?) before I got distracted and wrote STe Bombaman.. Sure its probably all on a SCSI disk in my garage along with the ICD and all the other hardware I had. Really must get around to sorting it all out one day, maybe when I retire in a few years... Recall considering using ColdFire back in the day but decided to go full PowerPC and rewrite all the assembler code.. Then went switched and went to Strongarm.. Been a great time the last 40 years being into all this as a hobby and as a career..

What does the classpath exemption for the GNU license mean. I can’t wrap my head around it.

Amazing work

This guy is actually 😍 amazing, thank you.!!

Dear Foss north. First: Thanks for this very interesting playlist. One question, which you touched in an episode before, but is still a vit unclear: why are cc licenses not suitable for software? Why can't these be used for software? What is the difference between, for example, a copyleft GPL and a cc license that explicitly states that license is possible only if the whole derivative artefact is licensed under the same license? Thanks!

Bravo

The only weakness in Fedora is that they have not adopted Calamares. They have the monstrosity called Anaconda.

確かに層は厚いよね～。

This looks like it would have been a very interesting presentation. Unfortunately I am struggling to understanding your English - I mean no offence as I am quite sure your English is far better than my French.

Great explanation!

This is Gold.

The sound is very bad low!! At least use a mic to produce professional course video!!

That was incredible! Whole lecture, informations from first hand! Does somebody knows actual name of his youtube channel? I can't find it...

Wonderful, insightful and inspiring talk. Thanks Martin and foss-north.

Awesome talk, Christo, good job!

these kind of videos saved me a lot of time by showing me the big picture of copyleft licenses. Thanks :D

Interesting, thanks for this. :)

One W0rd, MONERO.

I need a Video cable ..for my STF .. and i will be back on the game..

I really enjoy this presentation. It's awesome work. Thank you very much. However, when attempting to compile the demos, I get: undefined reference to `drmModeGetResources', `drmModeGetConnector', `drmModeFreeConnector', `drmModeFreeConnector' and `drmModeFreeResources'. These prototypes are expected to be defined in <xf86drm.h> or <xf86drmMode.h>, which I both have in my system. However, if I look into these files, none of them has the prototypes for these functions. I've done my best to find them, and have looked for alternative versions of libdrm, but came to a dead end. I would really appreciate a bit of help to get back on track. I may be missing something simple. Cheers !

KMS is actually a very good candidate for computer and console emulation, especially when a CRT monitor is used. Minimal display latency. What I haven't figured out yet is how to use a custom display mode without a custom EDID file, which restricts your runtime options.

Helpful

Cool thank you! Clear information without too much chit-chat.

ok.je comprend mieux pourquoi il y a autant de commentaires en Anglais dans vos vidéos.

Nice chat; Olof, 100% with you on the comment about old tools and flows, LOL, ages behind from what software is doing these days,

Très intéressant. Mais pourquoi continuer à supporter ce matériel obsolète et ce système tant comparable à Window ? Le Falcon à été trop long à venir et à déjà introduit des incompatibilités. Les clones et systèmes alternatifs encore plus. Et ne parlons pas du coldfire. En parallèle, avec Mint, c'est une bascule dans le monde Unix. C'était intéressant dans les années 90, mais depuis seul importe Unix et le matériel récent, en terme de coût performance compatibilité durabilité. Je respecte profondément la ferveur des utilisateurs Atari et Amiga. Juste pourquoi ne pas accepter le deuil et rejoindre le rang de l'histoire ? Où trouvez-vous encore la force de poursuivre cette aventure ?

IN FreeMiNT you can also yse a X11 Unix server! It is called X11-GemServer, in which you can run some low ressource Linux software as a clock.. I test it on a Falcon many years ago, it was very slow but it worked.

Atari and Amiga were similar machine, and had the same CEO "Jack Tramiel" (Who was in Commodore and Atari Corp)

The audio is horrible

Im subs btw

This is soo underated! I have to share this to all my community

Have to isolate since a neighbour has gotten Corona until i get answers on Friday if i have gotten it or not, so started listening to this podcast anyways any link or more information to that rms QT thing?

So, if an operating system works on RISC-V like Debian, does that mean anything that application that works for Debian now works on this CPU regardless of the instruction set?
