14:59 <mcirsta> hi chewitt. I managed to get your kernel from github and I am compiling it as a Manjaro package

14:59 <mcirsta> they have their own config file which I'm now using, any idea if there's something specific in the config file to build the Amlogic vdec

15:00 <mcirsta> btw how chewitt, narmstrong what do you use to build for aarch64 and how long does it take to build the kernel ? ( just curious )

15:06 <chewitt> this is the defconfig I use with LibreELEC https://github.com/chewitt/LibreELEC.tv/blob/amlogic-upstream/projects/Amlogic/linux/linux.aarch64.conf

15:06 <chewitt> it might be a bit minimal for a desktop OS like Manjaro

15:07 <chewitt> but @spikerguy who preps the Manjaro images should have everything needed, if not we can get him/them to add things

15:08 <chewitt> I'm cross compiling on a 32x core AMD TR2 box with 128GB ram and 4TB of nvme SSD

15:09 <chewitt> although work VMs occupy most space .. my LE build VM is 16GB RAM I think

15:09 <chewitt> although work VMs occupy most space .. my LE build VM is 16GB RAM I think

15:10 <chewitt> build time for a complete LibreELEC distro image is about 35-40 mins depending on what else is consuming cpu

15:10 <chewitt> if I shut everything else down it's about 26 mins, but there are things I host for work that can't be stopped

15:11 <chewitt> the kernel building part on it's own takes about 2-3 mins

15:12 <chewitt> but the way the build-system works, if it's just a respin with an extra patch or config change is closer to 30s

15:54 <mcirsta> OK, thanks for that. I'll just use the Manjaro config for now and I'll check if the vdec is in there , hopefully it is

15:55 <mcirsta> for some reason I though compiling on a aarch64 distro is better and managed to secure some Oracle cloud with 12 virtual Amprere I think cores

15:55 <mcirsta> it's decent

15:55 <mcirsta> 9 min to compile the Manjaro ARM kernel which is probably bigger than the LE one

19:46 <rockosov> Hi all! Let me introduce myself. I’m kernel developer from SberDevices. We are creating consumer devices based on Amlogic SoC, and started our internal work on the Amlogic upstream kernel support a few months ago. We already sent meson-ir-tx driver to upstream, and it was accepted. I hope we can help the community with Amlogic happy upstreaming.

20:34 <mcirsta> hi rockosov, if you can say , what kind of consumer devices

20:34 <mcirsta> more specifically will you be using the hardware vdec

20:36 <rockosov> Yes, sure, I can provide the links to our already released devices. Here you are https://sberdevices.ru/sberportal/, https://sberdevices.ru/sberboxtop/, https://sberdevices.ru/sberbox/

20:36 <mcirsta> yes, I saw now

20:37 <mcirsta> I actually think it's a great idea so use mainline for Amlogic, I've just tested on an old S912 TV box I had and most things work great

20:37 <mcirsta> except for one thing the HW vdec

20:38 <mcirsta> I was actually talking with the guys here about how I could help with the hardware vdec for Amlogic

20:38 <rockosov> We are using hardware vdec, but still based on Amlogic internal driver

20:38 <mcirsta> unfortunately I'm a c++ dev , not a kernel or embedded one

20:40 <mcirsta> vdec seems to be one of the last if not the last piece for proper mainline support

20:40 <rockosov> I’m in kernel developers teams around 7 engineers. We are maintain all low level things in the our devices. Our goal is transition to upstream code and valuable contribution to it of course

20:41 <mcirsta> that would indeed be great

20:41 <rockosov> I’m not currently understand a status for other video pipeline support

20:41 <rockosov> Amlogic has many things inside like GDC, ge2d etc

20:42 <mcirsta> and it would even make the news , as the first Amlogic hardware to use mainline

20:42 <mcirsta> I don't know much about the current vdec status either

20:42 <mcirsta> just that there was work done but now it needs to be brought up to date and finalized

20:43 <rockosov> I thought VIM3 and some Odroid devices already use mainline, haven’t?

20:43 <mcirsta> I just started looking into it and setting up my development environment today

20:44 <mcirsta> I don't think so, maybe there are some mainline images

20:44 <mcirsta> but you cannot really use mainline if you want vdec

20:44 <mcirsta> as far I know at least

20:44 <mcirsta> besides I don't count those as they're not consumer devices

20:45 <mcirsta> I think when you deliver stuff to consumers then you're shipping a product

20:45 <mcirsta> dev boards are nice of course but they're for geeks :)

20:46 <mcirsta> even as a geek I wouldn't really take a VIM3 and connect it to my TV

20:46 <mcirsta> it would care my wife :D

21:33 <rockosov> You are right! :-) but dev boards are good choice to debug reference flows for comparing with production device situation
