Ubuntu Studio : checking & configuring RTIRQ handler interrupts
Well, the tile says it all, I think. I 've been reading things about this topic here and in other forums, I already have the rtirq-init script installed and changed the line GRUB_CMDLINE_LINUX="threadirqs" in /etc/init.d/rtirq status, with no perceived results.
If I type rtirq status in the terminal, all I get is "command not found", so I guess there are quite a few things I 'm certainly missing. Could any of you, wizards, share a newbie-friendly way to tackle this topic? Thanks so much in advance. |

Code:
GRUB_CMDLINE_LINUX="threadirqs" For the command you need root rights: Code:
sudo /etc/init.d/rtirq status The output should be similar to this: Code:
PID CLS RTPRIO NI PRI %CPU STAT COMMAND 255 FF 95 - 135 6.6 S irq/32-xhci_hcd 275 FF 94 - 134 0.0 S irq/33-xhci_hcd 9 TS - 0 38 0.1 S ksoftirqd/0 18 TS - 0 38 0.1 S ksoftirqd/1 24 TS - 0 38 0.2 R ksoftirqd/2 With Code:
sudo /etc/init.d/rtirq start Code:
sudo /etc/init.d/rtirq stop What are you trying to achieve with these changes?

Hi Lilith, and thanks for the reply!
Basically, I 'm trying to make sure that my system has all the necessary tweaks to achieve a reasonably good performance of Kontakt, as other users have reported it as possible. While not at the studio right now, I'll follow your tips and post back here my results. Anything else you can say on this subject? I have other aspects of audio tweaks in Linux covered by Ubuntu Studio Controls, but I have some doubts regarding this, and Kontakt is xrunning like crazy on a I7 machine with 32 Gbs of RAM and SSDs. Together with my attempt to install Liquorix -failed by now, as I comment in the other thread - I'm trying to get all tweakable aspects of the system ready for an optimal audio performance. Any further insights are deeply appreciated... |

I don't have any experiences with running Win plugins. Have you tried the xruncounterscript to see how optimized your machine is?
https://github.com/Gimmeapill/xruncounter I also deinstalled the Liquorix Kernel again today as CPU usage was higher compared to the stock kernel.

Setting IRQ priorities: start [ICE1724] irq=18 pid=619 prio=90: OK. Setting IRQ priorities: start [ehci_hcd] irq=23 pid=156 prio=85: OK. Setting IRQ priorities: start [ehci_hcd] irq=23 pid=157 prio=84: OK. Setting IRQ priorities: start [xhci_hcd] irq=28 pid=158 prio=85: OK. Is this allright? Kontakt continues xrunning like crazy, anyway... |

Have a look here:
https://linuxmusicians.com/viewtopic.php?t=19276 Especially https://linuxmusicians.com/viewtopic...106591#p106591 Do you get more xruns when you use the mouse or keyboard?

Well, the ICE1724 was the old PCI soundcard, which I've just removed. I also had my onboard audio card disabled - something which I wasn't sure about -. I'm still having sound interrupt issues with the USB Komplete Audio 6, although the realtimesystemquickconfigscan script shows everything as "good" (except for the "SET IRQ of the sound card" message).
I'll do something, if you don't mind : I'll create another thread to deal with these kind of issues regarding Linux realtime audio (and I'll try to leave the first posts as placeholders to arrange, little by little, a newbie's summary with all the recipes that the experts contribute in the most clear way possible). I feel I'm opening threads here and there but the info remains completely fragmented and scattered across threads/forums/web pages, etc... |
