Panfrost does not currently support the Mali G31/52 (Bifrost) chips used in G12A/G12B/SM1 hardware and I don't see that changing for a while yet. It's not an issue though as we have all the required blobs and can use those; hence we are shipping two images (AMLGX with lima/panfrost and AMLG12 with blobs) which are working on a range of newer hardware. There are no plans to drop support for S905 and up devices but it is a large task and developers have proper jobs and families so progress comes as it comes; we're not forcing the schedule. We will push a master branch bump to Linux 5.4.x soon; although there are ongoing changes to the video decoding drivers that need corresponding changes to Kodi/ffmpeg so our master branch will not be as usable as Linux 5.2/5.3 was for a while.

Great news! But wat a huge task. And to think that all this is being accomplished by volunteers coding in their spare time, awesome.

Am i right to assume that s802 - s805 - s812 are being considered obsolete?

Great to hear! Always enlightening to read your explanations, makes things a bit more understandable. Could the succesful development of panfrost mean that we possibly can expect future LE release on mainstream linux with support for s905x2 - s905x3 - s922 ? This all seems a huge task. Is there any prediction when all this magic will be reality?

Will s905* will be supported in future LE releases? (still going strong, great soc!)

it has been a while since i dropped in here asking this question, have been wondering how things are now..., if i might ask chewitt, status on the s912, last i can remember is that after it was being cursed upon for a long time a solution for the missing fbdev mail libraries was developed in using libhybris and android gralloc mali drivers. is this still the case? i seem to remember something about an opensource driver being developed for the s912, did that development succeed?I think this was called panfrost?

Why would you even bother trying to run illegal addons? There has been so much work put in LE / Kodi to get genuine video services like amazon prime and netflix working, so much effort to get adaptive streaming and widevine running. you wanna waste all that effort with some shitty add-on?

just get a decent supported device, dont be cheap and subscribe to your favourite streaming provider, and you're all set. you can even get something x86 with a bluray drive, buy second hand bluray's, then you've got yourself dirt cheap high quality content.

Looks like Dell is blocking max. performance at firmware level. Maybe max. performance leads to heat problems, or whatever issues.

The only "solution" I see is a firmware hack.

That would make sense, because these 3040 boxes are really tiny. They fit in the palm of your hand. I already was wondering about the incredible small footprint these cherry trail units have. This was what attracted me to them in the first place. I can imagine that the current "normal" power setting is good enough for them to just do thin client tasks on a simple linux os. Nothing fancy there. Doing h264 30mbit 1080p decode is a whole other story. Could well be they burn on "perfomance" power mode, looking at how tiny they are.

Ask Dell, they should know what they write on boot. I'm very sure the video stop comes from UEFI, not LE.

I believe you! Problem is that these dell wyse 3040 boxes are being sold primarely as thinclients. Seems no one at dell is waiting for a guy asking about uefi settings. Even reimaging these devices is a pain in the ***, since they use some kind of deployment tool, with uefi pxe booting.

That leaves me with almost no options; i was hoping i could get the box booting in csm legacy mode and run LE like that, but that also seems to easy to be true. CSM booting disappeared as soon as i enabled uefi booting and i'm searching for a way to get csm module enabled again.

These cherry trail boxes, even a fancy dell wyse, keep giving me a headache!

Quote from Da Flex

Set your energy preference back to "performance" at UEFI settings.

This is a problem, i've searched the dell firmware back and over twice, there are no energy preference settings. I can set c-states, turbo b**st, and something else c-states (cant remember), but no performance settings.

anyone?

It has no dedicated gpu, just cherrytrail graphics. This is why i was expecting it to work flawless... I've added the dmesg.

This is a weird problem: i have this Dell Wyse 3040 thin client, a great little device with dual displayport output. It runs stock linux, which can easily be replaced with another os. This is a cherry trail box, is has an atom x5-z8350 with native 64bit uefi firmware (yes, finally!).

LE installs and runs great in 64bit uefi mode, no problem there. Now the only problem is: when playing back video, video runs for about 3 seconds and then freezes. I can revert back to menu (the frozen video reverts to background), and then i have to stop the stalled video manually. Combined with a flirc usb receiver this tiny box makes a really great LE device, so i'm hoping the video playback issue can be resolved.

Do yourself a favour, throw away the 32bit efi crap devices. I had a couple of these devices, even a very expensive industrial grade device. If it doesnt work it doesnt work. 32bit efi is just a nasty way of crippling an otherwise perfectly fine 64bit cpu. A way for the industry to limit use of potentional usefull hardware to next to nothing.

Especially the intel cherry trail devices often come with 32bit efi, those cheap little plastic chinese boxes with sub par cooling. My humble opinion: save a little more and get yourself something better, like intel n3700 or j5005 devices, from a well known brand (with decent cooling).

would you mind sharing what is needed to get netflix working on kodi? Im sick of having to jump between my tv and the kodi setup

Go to the Kodi forum -> video add-on section. There you will find the unofficial netflix repository stuff.Remember that all video decoding on linux is done in software, so you need more then a little device to get 1080p working (just found out myself. Runs great on my core i5 mediacenter. a low end atom x5 however...)

Are there any noticeable performance or feature benefits in updating to LE 9.0.0?

I'm currently running "8.2.3.-GUI-options" OC'ed on a C2.

inputstream adaptive, drm, netflix and amazon vod support are the most important reasons for me. Finally a good way to watch netflix (1:1 pixelmapping, framerate switching, hq decoding, fast interface). LE 9 / Kodi 18 was for me the reason to finally get a netflix subscription. Just works out of the box, no need to tweak funky patches, just download a few add-ons and you're ready.

S912 is now working on mainline linux kernels using the "panfrost" open-source alternative to the non-existent ARM mali blob and balbes150 has a testing image available via his K18 release thread for the curious to look at. Panfrost is still under fluid development and it's not stable enough for real-world use yet; there are memory leaks so you can play video but navigating around in the GUI eventually triggers OOM crashes. It's making rapid progress though, and is attracting lots of known names from the Linux graphics community who are helping to move things forwards (even ARM's open-source group are engaged) so in the next couple of months we should reach a point where issues are resolved or reduced enough for proper public testing to start.

It is beyond my comprehension how one would be able to develop an opensource linux gpu driver. Is this all done without cooperation from ARM? As i try to imagine, one should need some tech docs, documentation to start "writing" the code? I keep being amazed how much hardcore programmers are still out there trying to achieve great things.

Am i right to conclude that the current available LE images for s912 are all based on the android driver on lybhybris?

And finally, if im not overwelcoming my stay , it's great to hear that s912 development on opensource gpu driver is on its way. I also read that rockchip LE , what years back was unimaginable, now is fully supported on rk3399 and rk3328. If i might ask chewitt , at this point in time, would you go the s912 route or choose the more powerfull rk3399 rock64pro solution?

Been away from the forums for a while and been a bit busy over the S.Hemisphere Holiday period. Been doing some testing as well.

Previously users have been wary of the S912 with it's ARM Mali T820 GPU due to uncertainty with properly implemented Linux Mali GPU drivers which will be definitely be needed for Kodi v19 M. Which is at least a year away.

As chewitt has already demonstrated in previous posts, work is already underway to add such stable T820 GPU driver support for Kodi v19 rendering.

The S912 always had a problem with upcoming Inputstream-Adaptive - Linux / CoreELEC Kodi Leia - ffmpeg (CPU) h.264 decoding and rendering - needed for Leia Netflix Addon streaming. In fact you could not even ffmpeg decode and stream 720p

The Kodi Leia rending performance issue has been hunted down by @fritsch and @peak3d just today and there is now a noticeable increase in ffmpeg decoding and rendering performance on ARM platforms. 720p Netflix now works smoothly with Kodi Leia on the S912.

See the Kodi Leia PR HERE

In fact I can decode and playback 1080p h264 Bluray Rips and (low bitrate) 1080p 10bit HEVC - using CPU software decoding alone on the S912 - MINIX U9.

Be aware I'm using newer libhybris OpenGLES 2.0/3.2 - which I hope to include in future LE / CE versions - they increase rendering performance as well, especially with GLES 3.2 in Android 6.0 onwards.

The GPU Overclocked S912 is now equal quickest S9xx platform I use, rivalling the SDR only Overclocked ODROID C2.

Oh and the S912, Kodi dirtyregions workaround for S912 Subtitle stuttering will no longer be needed for Linux Kodi Leia with the above PR.

Details about that HERE

I also have not read about development on s912 for a while . The last thing i read over about a year ago is that there was no descent driver and library for linux. How have things gone since then? What was said back then is that there was no libmali.so for the mali-t820 in the s912. efforts to get LE ported included using the android driver + library, which back then resulted in an generic "do-not-buy" advice for the s912. Is this still the case? Or has the appropriate driver and library become available? The advice used to be, when going the amlogic route, buy s905 duo to proper software support.

given that your internal android is already overwritten, it does not hurt to run installtointernal again.

It tried it twice. I can boot le fine from sd card, ssh into in, installtointernal, looks allright, no errors, but the box refuses to boot from internal flash. Also when i boot le from sd card and then choose reboot from internal (and remove the sd card), the screen just stays black.

I'm running this build on an mxq pro 4k, s905 with realtek wifi, 1gb ram, 8gb flash. Running from sd card works fine. I wish to run LE from internal flash. After installtointernal everything seems to go well and i get no error messages. But after a reboot the box wont boot from internal flash (screen stays black). When i power off the device and insert the sd card it again boots LE fine. Is there anything i can try or do to get this box to boot from internal flash?

You need to find a working remote.conf for you box and place it in the Configfiles folder through Samba

Thank's. Why didnt i remember that? For future reference: it seems i have become an old geezer
