I noticed we're now shipping several kodi packages, kodi-bin (x11), kodi-gbm, and kodi-wayland. I'm wondering about advantages/disadvantages to each of these. For example, for an Intel graphics scenario, what package would be recommended and why?
EDIT: Please check my wiki edit: https://wiki.archlinux.org/index.php?ti … did=568031 which is not exhaustive based on my research but is a good start.

The inadequacies of GBM are listed in the GBM roadmap, todo list and issue list #14876.

Nice, thanks for sharing. I noticed higher CPU usage while idle on the kodi GUI comparing x11 to gbm... it was only a single experiment, playback of the same file watching CPU usage via top and load average as reported by uptime after playing for 20 min. Perhaps a bug with dirty frames or the like?
Under x11:
load average: 1.07, 1.11, 0.84
Idle CPU 3-4% and playback CPU 12-14%
Under gbm:
load average: 1.19, 1.10, 1.01
Idle CPU 11-12% and playback CPU 10-12%

Funny, I was looking into the same thing. What video driver are you using?
Reading about the fact that gbm runs directly on the video driver, i thought it would be a good choice for a stand alone media player, but looking at your idle stats makes me doubt again.
Support for hardware decoding is said to be limited, but LibreElec will soon be GBM only:

I guess Nvidia users are out

Intel onboard. More data, just loading kodi (not playing anything) so idle.
After 1 h 20 min, GBM:
% ps -p $(pidof kodi-gbm) -o %cpu,%mem,cmd
%CPU %MEM CMD
8.1 1.5 /usr/lib/kodi/kodi-gbm --standalone
% uptime
16:42:04 up 2:12, 1 user, load average: 0.16, 0.09, 0.07
And then switching to x11 and repeating:
ps -p $(pidof kodi-x11) -o %cpu,%mem,cmd
%CPU %MEM CMD
3.4 1.4 /usr/lib/kodi/kodi-x11 --standalone
% uptime
18:51:13 up 1:20, 1 user, load average: 0.12, 0.08, 0.02

Sounds like there is something that keeps triggering the CPU, this happened before on Intel platforms:

Have you tried different kernels?
I'll have a go on my AMD E350 tonight, see what happens.

Haven't played with it much beyond what I shared here.

Just FTR, higher CPU usage confirmed on RX550 too.
