Just to try I loaded this image on my Kaby Lake 7th Gen NUC NUC7i5BNK and had no luck. Trying to playback HDR content just results in a black screen and I wasn't able to select any sound options other than Bluetooth presume the image is missing the drivers for the platform.
Good to see work continuing on this though as LibreElec would definitely be my platform of choice given the option.
LSPCON support for HDR is not merged yet into kernel
Oh... Do you perhaps know something we don't?
"Once HDR support is fully baked (right now it is far from)"
That doesn't sound like HDR support is right around the corner.
guys from intel was testing themselves
These patches tested on below test environment.
Test Environment:
- Tested System: GLK and Gen11 platform.
- Monitor: Dell UP2718Q 4K HDR Monitor.
- In order to test DP HDR10, test environment uses patched Kodi-gbm,
patched Media driver and HDR10 video.
You can find these on below.
[patched Kodi-gbm]
- repo: https://github.com/Kwiboo/xbmc/tree/drmprime-hdr
[download 4K HDR video file]
- link: https://4kmedia.org/lg-new-york-hdr-uhd-4k-demo/
[Media Driver for GLK]
- repo https://gitlab.freedesktop.org/emersion/intel-vaapi-driver
master branch
[Media Driver for ICL]
- repo: https://github.com/harishkrupo/media-driver/tree/p010_compositand they pointed Kodi as software to test 
and not fully baked ? yes as the standard we have now HDR, HDR10, HDR10+, Dolby Vision etc.
and who know what more we can expect 
but as basic HDR support in linux looks like we are there.
In ubuntu 19.10 in changelog you will find
and what I see on patchwork drm-intel incoming more for devices with LSPCON from Gen9 up
and HDR10 with DP 1.4
I know still are some incompatibility example with Samsung HDR TV, which is actually issue of intel driver/
something with driver … that why even after kodi didn't started. That not installer issue, I will try port kernel config from ubuntu
no problem but that will take ages 
anyway I will post today build based on kernel 4.16 from ubuntu where users reported is working fine with Ryzen APU just in case if you will want test
@gwilly you tested this build ?
Sendspace.com Mobile File <-LibreELEC-Generic.x86_64-9.0-devel-20180529211555-85b8697.img.gz
unpack and replace KERNEL and SYSTEM on USB stick 
please try this second build and also check your bios settings
updated: I found some patch I will prepare next build
please check 1 post and test, thx
Update: I read a lot of people have same problem with Debian or ubuntu
There is a fix for my Debian error actually. If you have a fuzzed up image like me, where your image appears as if it had scan lines to the point that it is unrecognizable...
Firstly I reccomend you install Debian testing. And don't install it the usual reccomended way by first installing stable and then switching to testing sources, Install it by directly downloading the testing installer. That is my reccomendation.
Now if you have an Asrock motherboard or similar go to your BIOS/UEFI settings -> Boot settings and change CSM(compatibility support module) to disabled. Save and reboot.
Now the usual debian installer will boot and you will directly install Debian testing. Don't forget to apt update and apt upgrade and apt dist-upgrade(just in case), so you get the 4.16 kernel.
Now the 4.16 kernel is even more unstable with Vega 8 than the 4.17 kernel was on my Manjaro install, but the 4.17 kernel will land in the Testing repo in about a month. And hey, you now have Debian.
if you find time please test
1. Try this one with Bios Settings also they advised to update bios to latest
(go to your BIOS/UEFI settings -> Boot settings and change CSM(compatibility support module) to disabled. Save and reboot.)
2. try this build below - I updated llvm, mesa, and replaces firmware for Raven APU
you need over ssh do it this on my LE build
wget http://lrusak.libreelec.tv/public/modetest
systemctl stop kodi
./modetest | pastebinit@burllin and other owners of AMD Raven APU please test my build from
Experimental build AMD GPU (Vega, Ryzen APU) I need some testers because I don't have own hardware
upgrade first LSPCON - HDMI Firmware before you jump from Windows into LE, latest firmware have fixes for HD audio
KarstenL680 please check pci-ids from GPU - if its "15DD" should work - command lspci on ubuntu or libreleec - if SSH work.
also dmesg will helpful - maybe some modules/drivers are missing from mainboard. I don't have this CPU/mainboard- so I need logs for try get this working
also we can try add to syslinux this:
amdgpu.exp_hw_support=1
gwilly7 try maybe first RUN from stick - do not use installer, then we will be see if at least booting and starting kodi
or what is read
Make sure you do not have
nomodesetorvga=as a kernel parameter, sinceamdgpurequires KMS.
source: https://wiki.archlinux.org/index.php/amdgpu#enable_early_kms
so from syslinux.cfg remove - vga=current and try again
Otter that card this is Polaris - so should works
looks perfect

its working about iwlwifi-firmware use this source with latest kernels GitHub - piotrasd/iwlwifi-firmware: files used in the iwlwifi-firmware package
I updated all firmwares
today I will post
Hi here experimental build with AMD GPU support
Sendspace.com Mobile File <-- updated link
KNOWING ISSUE:
- popping sound in GUI
TO TEST on Raven APU
update 1. - here build with updated mesa, llvm and older Raven firmware
update 2. - here added patch/fix for artefacts (AMD X.Org drivers - Patchwork)
update 3. - shot in blind kernel used in ubuntu with few changes for amd (reported by users as worked)
