    GPU memory is fixed at boot time and we already optimised consumption. Kernel caching has a simple rule: "if you understand the kernel documentation, do what you like, else leave alone" and since 99.99% of users will not understand kernel memory architecture it's best left alone. On the Kodi side users like to tweak cache/buffers settings thus undoing thousands of man-hours of effort to optimise the default settings with a ham-fisted bodge from a forum post where a user with a different use-case and no great clue about the underlying mechanisms said it made things better. As a broad rule cache settting changes will fix one thing and cause three more things. So feel free to go nuts .. do the reading (lots of kernel docs, RPi docs, Kodi docs are out there) but when it all makes no different or causes issues - revert back to the defaults and marvel at how things just work again.

    Hi, I understand what you're saying, and you've convinced me.

    Thank you for these explanations !

    Hi,

    I have a few more questions.

    I would like to do a stress test to check the stability, i tried this command: journalctl -f | grep -i underv but it doesn't work.

    And I also wanted to know if it's possible to optimize the rpi, I'm not looking for OC, but to disable or enable useful elements or not. to reduce consumption.

    I'm thinking of the files config.xml and advancedsettings.xml

    Just optimize the device

    The initialization of the CEC adapter has a bug. On your working LE 12.0.1:

    On your non-working LE 13 nightly (20241103-f662bea):

    Code

    2024-11-05 16:49:04.832 T:1046    debug <general>: Thread PeripBusCEC 140732832476800 terminating

    In the working log, the CEC adapter is registered at /dev/cec1, in the non-working log at Linux.

    I've already reported the bug to the devs. Stay tuned.

    Ok, if I can't do anything on my side. I'll wait with my rpi3 again
