Hi everybody,

I recently bought a Core i5-11500 aka Rocket Lake CPU with a Z590 Mainboard (to be mor specific: ASUS ROG STRIX Z590-I GAMING WIFI).
My current setup is listed in my signature. My plan was to take my nvme ssd and put it into the new mainboard........

First problem I stumbled upon, with an integrated graphics card, the Z590 chipset doesn't allow you to run legacy mode, csm as ASUS calls it.
So I grabbed gparted and freed some space for an EFI partition and installed what was necessary (took me a little while).
After that was successful I fired up the new setup and the result was "default" display with a resolution of 1024x768....

With the help of some google-fu I found out that the drivers are net active from the scratch
You have to enable the graphics card with it's ID via modprobe (I also saw an ID of 4c8b):

Code:

options i915 force_probe=4c8a

Also in GRUB_CMDLINE_LINUX

Code:

i915.force_probe=4c8a

With that I had my 4k@60
BUT, no hardware acceleration enabled. Also one weird thing, my mceIR didn't work properly anymore.

Maybe it was too early to hope it would work

So I put my ssd into my current system back and everything was back to normal and kickin.
I will try a fresh install of Ubuntu 20 or maybe 21 (not sure for now).

Did anybody else tried out firing up a RocketLake on Ubuntu?
I thought it would be nice to have a thread to discuss findings and ideas

Not exactly sure when RKL support was added to intel-media but it appears to be in intel-media-20.3 as the first mention so might need Hirsute.

So I had time to install a fresh system.
@bluzee after what you mentioned, I installed an Ubuntu 21 (Hirsute) but sadly that didn't turned out to be enough.
Also worth mentioning, I installed drivers from oibafs repo with Kodi 19

Just this weekend i put together an Core i5-11500 system but using Arch linux, sadly i can't get vaapi decoding working in kodi(black screen) or mythfrontend(picture but green/distorted).
but it does work via mpv --hwdec=vaapi

spent to much time setting up services and getting this far i will post debug logs this weekend.

I will try mesa 21.2 on the weekend, there seems to be some changes in that reagard, hopefully it will enable hardware decoding

Mesa doesn't provide hardware decoding on Intel at all. You need to install a recent version of intel-media-va-driver-non-free (Ubuntu package name).

logs as promised, any idea why i get a black screen in kodi?

currently having to watch with hardware decoding off.

Wonder if perhaps Kodi will need to be compiled with newer version of ffmpeg?

I am also still not able to play hardware accelrated video files, only software decoding.
I saw that the Kodi repo isn't doesn't include the package for 21.04 Hirsute, I got a Kodi version which is compiled by Debian. As I can recall, that is not recommended to install that package as the Debian team does some different thing when compiling.

so turning on Expert mode then disabling "Prefer VAAPI Render Method" shows a picture.

vaapi decoding looks(?) like its working.

edit: using 5.12.0-1-mainline

I'd say it looks like it's working

That didn't work for me sadly :/

Had to cut off some repeating lines in kodi.log as it was too big for pastebinit.

I remembered that I've read to set the BIOS setting iGPU to auto and not to integrated. After doing so, hardware accelration worked.

But playing 4k Videos or a video with an Atmos stream breaks playback and I just get a blank screen.

[deadite66]

glad you got it sorted, from what i gather from another post there is a cpu usage increase bypassing the preferred method, by how much i wonder.

using a nofan cr-80eh so low cpu preferred

edit: tried to play a 4k file and got a black screen on it too, so not a complete fix.

looks like were on our own for a while.

@deadite66 - You mentioned being on Arch.  Does decoding work if you try playing the video from ffmpeg downloaded from the official repos?

If you do not see errors from the following which just decodes using vaapi (codec benchmark), then perhaps the version of ffmpeg shipped with 19.1 (4.3.2) doesn't support it?  Currently, 4.4 is in the official repos.

Code:

VID=/path/to/your/video.mp4
ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i $VID -f null -

Alternatively, you could build ffmpeg 4.3.2 on Arch and repeat to confirm support and that it's not something in Kodi causing the issue.
