Thank you David,
I kept i8042 in
RTIRQ_NAME_LIST because it was present in the default
configuration of rtirq. I have
now removed it from RTIRQ_NAME_LIST, but the situation doesn't
seem to have changed.
Shared memory:
I don't know how
to find it, could you please tell me how to check it
out?

I don't know about the rest of the settings, but why is i8042 (PS/2 keyboard/mouse controller) on the RTIRQ_NAME_LIST?
Does the laptop use shared system memory for video?

I have a setup that I use in my live sets made with an ASUS N551 laptops and a NI Komplete Audio 6, which allows me to play without XRUNS at 64 frames / period with a modular approach (Qtractor, LinuxSampler, Yoshimi, SooperLooper, PureData). The whole thing runs on Debian Stretch with AVLinux 4.9.47-rt37avl2 kernel. I am quite happy with the performance of this setup, but I started having XRUNS when I added real-time video management as well. Those issues made me notice that the system runs without XRUNS only if XOrg is not stressed much, while it starts producing XRUNS when I play a video, or when I open the browser, or even when I quickly move or resize a window. I would like to understand if the problem is due to an incorrect configuration of realtime priorities, or to something that I have not yet managed to trap. I currently use these configurations: [Xorg] The video driver is i915. I read on the internet that: "If your graphic card was manufactured in 2007 and newer, try uninstalling the xserver-xorg-video-intel package and use the builtin modesetting driver (xserver-xorg-core) instead" Questions: - I uninstalled xserver-xorg-video-intel, but I still see the i915 driver: is that correct, or should I see another driver? [rtirq] RTIRQ_NAME_LIST = "snd usb i8042" RTIRQ_PRIO_HIGH = 90 RTIRQ_PRIO_DECR = 5 RTIRQ_PRIO_LOW = 51 RTIRQ_RESET_ALL = 0 RTIRQ_NON_THREADED = "rtc snd" Questions: - rtc must be in "NON_THREADED", or in "RTIRQ_NAME_LIST"? - in "RTIRQ_NAME_LIST" can I remove "usb" and put only the item that manages my USB card? Should it be xhci? - can i take i8042 off the list? - is it recommended to use RTIRQ_RESET_ALL = 1 to override all other IRQs? [jackd] jackd -P83 -dalsa -dhw: K6 -r44100 -p64 -n2 -I1 Questions: - the priority must be lower than those that are set to the IRQs by rtirq? [limits.conf] @audio - rtprio 99 # maximum realtime priority @audio - memlock unlimited # maximum locked-in-memory address space (KB) Questions: - what is the recommended value of rtprio in 2020? On the internet I find 90, 95 and 99 Can you help me do a checkup of my configuration? Thanks!
