afaik at least di and scaling are not there

Both DI and scaling are fully functional with GBM + VAAPI (DRM PRIME disabled.) There is absolutely no reason to use X11 on Intel hardware

Quote from CvH

depends at not upstreamed patches for kodi and ffmpeg

Those are only DRM PRIME stuff. GBM VAAPI is fully functional (without HDR) in current LE master without those non-upstreamed patches.

Your build, would it work on a NUC6CAYB to enable HDR output ?

Try the build from post #426. It includes Linux HDR patches for MCA LSPCON. No idea if it will work or not.

Does anyone here use a Gemini Lake box with a Samsung 4K TV (2019 or 2020 model)?

After experiencing some annoying HDMI issues with 4K modes (e.g. intermittent white dots after a mode change, with known good cables) I decided to poke around in Intel driver and found the problem. Apparently, my Samsung TV doesn't like Intel's implementation of HDMI Scrambling.

I disabled scrambling with a below patch and all issues are gone.

I hope X11 would be dropped after LE 10 is branched out. I feel like it is holding back the development of Generic x86.

I don't understand what you mean by that. My builds are compiled from LE git master + HDR patches from lrusak's git repo + some minor changes to make it all compile and work.

Deinterlacing is not implemented (yet) for DRM PRIME.

You are using the wrong branch

I used this one. Is it the right one? HDR worked on Gemini Lake and (reportedly) on Tiger Lake. Didn't work on Athlon 200GE.

Quote from lrusak

Also, the AMD drivers (IMO) are some of the best.

Ok, but I can make a list of weird issues that are exclusive to AMD and not present on Intel.

Like this issue for example which I reported to AMD almost a year ago and it is still not fixed.

Quote from Deezle

Do you expect that the audio passthrough issues on Intel (e.g. NUC11PAHi)

The audio passthrough issue has been reported to Intel driver people but no one's in a hurry to fix it.

Quote from Deezle

May I ask you which machine you own yourself or plan to purchase?

I own an Asrock J4105B-ITX (Gemini Lake) board. I plan to upgrade it at some point to a Tiger Lake based mini-ITX board (most likely Celeron 6305 or Pentium Gold 7505) when they are available.

Quote from pletopia

My biggest concerns are does it do 10bit 4k HDR properly?

Current work-in-progress HDR code from lrusak's git repo (which I use for my LE builds) does not work on AMD. No idea when or if it will ever work.

But the biggest concern should be AMD's linux GPU driver quality, which is kinda crap. I encountered some nasty issues when testing LE on Athlon 200GE APU with Vega graphics.

The audio passthrough issues on Intel are nothing compared to general crappiness of AMD drivers.

Quote from nvdias

Is there any plans for the Crazycat's driver with LibreELEC 10 ? Or TBS drivers ?

DVB Addons Update by CvH · Pull Request #5165 · LibreELEC/LibreELEC.tv · GitHub

I also posted a kernel patch for TBS 5520SE here.

No dolby vision support in Linux.

Is there a way to get it running on the Minix u9-h?

No.

Quote from luckylukz

It says RC1

It was compiled from yesterday's git master and is only a couple of minor commits behind.

Quote from luckylukz

Would apreciate a build to test.

That's what I uploaded yesterday.

Quote from luckylukz

Just to clarify and remove confusion is this specifically for the Intel Iris X Graphics or will it also work for the Intel UHD Graphics in the i3 model.

All NUC11s use Tiger Lake-U SoC with the same GPU. The only difference is the number of enabled EUs (48 on i3, 80 on i5 and 96 on i7).

So yeah, it will work.

Quote from Nekromantik

should it also work on nuc 11 Pro?

Buy it and tell us

I don't see why it wouldn't work.

Quote from luckylukz

Confirmed HDR is working!

That's great news!

But keep in mind that HDR code is early and has some bugs.

For example, HDR mode sometimes does not switch off when you switch from HDR to SDR video.

Another bug I noticed - if you switch the TV off and then on again - HDR may not work anymore and Kodi must be restarted to fix this.
