MIPI-DSI is available on both RPi and Khadas boards. It would seem to require kernel module support, though, with (from the little I've read) a display controller-specific driver. Are any of those even present within the LibreELEC kernel?
The linux.arm.conf file for libreelec-9.2 does have CONFIG_DRM_MIPI_DSI set to y.
I don't know what other device drivers might be needed, though. The setup seems the same for the current master and Linux 5.9.2.
Finally, on a semi-related note, does LibreELEC support installing Entware or is that just a CoreELEC (convenience) feature?
Well, I can at least answer that question. LE does not seem to have installentware.
Hello,
I'm interested in extending kodi_panel to use more than just SPI-connected panels. I'd like to be able to use an IPS panel (better colors, wider viewing angles), and I've picked up an RPi 4. I'm unsure what direction to pursue for connectivity -- DSI, DPI, or HDMI.
To clarify my intent, I'm not interested in dynamically switching the role of the displays. The primary HDMI output (which, for lack of additional knowledge, I'll call fb0) is always for Kodi's use, connected to an AVR and 4k TV. Audio for movies would also make use of that HDMI connection, while 2-channel music makes use of a USB-attached DAC (thanks to the Audio Profiles addon).
I'm also not interested in running X (even for fb1). I'm content to render the front panel image using Pillow and, ideally, handle touchscreen events in kodi_panel as well -- all in user-space Python. (Hopefully all of that actually works!)
Of particular concern is whether fb0 retains hardware-acceleration and whether fb0 remains independent (with regard to resolution, color depth, display freq) from the front-panel display. The front-panel display would be limited to something like 480x800 resolution (with 24b color depth). I'm not looking for a 4k 10" front panel. Well, not yet. 
So, on to some general questions...
Hopefully, the "lift" for any prerequisites can be kept fairly light. I'd still like to run LibreELEC / CoreELEC, since the widget's role is just an HTPC.
Any thoughts on which connection method has the most longevity? HDMI seems the obvious choice, but I'm concerned that fb0 and fb1 aren't completely independent. I only recently realized that DSI is available on the Khadas boards, so that did raise my interest some.

Thanks for any discussion! Regards,

Experimenting further, UPnP/DLNA services work as expected (after reboot) if Kodi start is delayed until networking is available (one of the LibreELEC settings).
One always forgets setup tweaks after a while.
Using 9.0 Beta 2 on a Raspberry Pi, I'm finding that the UPnP/DLNA services setting doesn't appear to be "sticky". Settings are always correctly remembered if I bring them up, but (after a reboot) Kodi on the RPi is unable to connect to my DLNA server unless I first go in, disable, and then re-enable UPnP services. After that, everything works perfectly!
mlovell Hifi Shield works but there are no userspace alsa support. Which means you can only have simultaneous output with HDMI and Hifi Shield.
Ah, without the menu choice, I never thought to just hook up the RCA outputs! I'll give that a try.
Thanks.
Hello,
Is there support for the ODroid HiFi Shield Plus in any of the C2 community builds?
I found some mention of the HiFi Shield in various posts on the LE forum, including statements of it working out-of-the-box (I think) with kszaq's build. Trying both that one and raybuntu's, though, the DAC never comes up as an option for audio output. The two modules I've seen mentioned elsewhere, namely
don't appear to be available either.
Thanks for any advice,
Matt
[EDIT: typos]
With both LE 7.95.1 and 7.95.2 on a CuBox-i2eX using HDMI to a Yamaha receiver, set up with pass-through for all audio formats, the soundtrack for a movie cuts out for about a second every 4-8 seconds. Audio is fine for music playback (even multi-channel PCM audio) through that same HDMI connection.
Has anyone else observed this. Are there any logs that would help with diagnosis? (I'm an experienced Linux user, just not that familiar with Kodi.)
The same CuBox plays movies with DTS and TruHD audio fine (the same files, actually) with the last released OpenELEC.

Hmm... the 7.95.2 instance was under a network load (doing a scan) when the audio cut-outs were happening. With the scan concluded, playback seems to be normal. (I guess I'll have to watch a movie to make sure
The cutouts that were happening earlier with 7.95.1 were in the absence of any other activity (at least to me knowledge). Those drop-outs caused me to go back to OE for a bit.

Unfortunately, playback still isn't normal.
It does seem somewhat sensitive to load (even though onscreen debug information doesn't show either CPU core very heavily loaded) -- moving the mouse to activate controls seems to be able to trigger a momentary drop-out.
Any thoughts (logs to capture or other settings to try)?
Thanks,
Matt
