I simply downloaded the needed files and created the patch files with git diff.
e.g. for av201x .c:
git diff emptyfile av201x.c > 1.patch
then fixed the path/file name in .patch file.
There are probably better ways to do this (e.g. git cherry-pick) but it works for me.
Disable debug logging?
but sadly this is no longer available on dropbox
Looks like PCI-E cards are handled by tbsecp3 driver. You will also need to add av201x tuner driver and gx1133 demod driver.
and i am not sure one could do that in kodi too.
Also those kodi patches are for DRMPRIME which we don't use on x86.

What impact has it to only use 10 bit instead of 12?
None whatsoever.
Has anybody any pointers where i could open a bug for that?
how do i force 8 Bit or 10 Bit
For 8-bit:
systemctl stop kodi
./proptest 185 connector 191 8
systemctl start kodiHow do i edit the edid and change "SCDC Present"?
I used this. It's in CEA Extension 1 -> HDMI-Forum VSDB.

Also worth trying a custom EDID with "SCDC Present" bit set to "disabled".
IMO those dropouts are data errors related to Intel HDMI 2.0 implementation.
Settings - System - Power Saving - Shutdown Function - Suspend
This is supposed to be used with Shutdown function timer. It works as intended.
I think lrusak said on slack he will look into it. Unfortunately I have very little experience with pw.
I think Pipewire should only be enabled with Kodi 21/LE12.
Install tvheadend43 and pvr.hts, configure tvheadend via the web interface (default port is 9981). It should work
ls /dev/dvb/adapter0/ . You should see frontend0 is present if the driver successfully loaded
smp do you know how to build a version with pipewire?
Edit distributions/LibreELEC/options
PIPEWIRE_SUPPORT="yes"
KODI_PIPEWIRE_SUPPORT="yes"
ALSA_SUPPORT="no"
KODI_ALSA_SUPPORT="no"
PULSEAUDIO_SUPPORT="no"
KODI_PULSEAUDIO_SUPPORT="no"
Maybe it's worth trying to do a test build with pipewire to see if there's any improvement.
For those who only use the satellite tuner I modded the driver to disable the DVB-T/C tuner.
TBS 5520SE has 2 tuners attached to a single demod. DVB core apparently does not support 2 tuners on 1 demod so the driver used a hacky way to split the adapter in 2 virtual frontends. This cause all sorts of issues with tvheadend (e.g. "no free adapter available"). I modded the driver so si2157 DVB-T tuner is not attached and only 1 DVB-S frontend is created.
I've seen a similar issue on a Samsung TV. Usually, when a HDMI source device is powered down - the TV still detects that something is plugged in to the HDMI port. But some devices stop being detected when powered down, on the next boot TV "thinks" that a new device has been connected and some HDMI-related settings reset to defaults. As a workaround, you can try to connect the Pi to TV via a self-powered HDMI splitter/switch/extender.
but no issue when play recorder
I think this has something to do with how the realtime streams are handled by Kodi.
Could you try to play via pvr addon with this build? - LibreELEC-Generic.x86_64-12.0-devel-20231208072228-5b2d3ec.img.gz
