[Fedora-music-list] threadirqs kernel parameter with standard kernels...

Hi all Cab any one confirm this? I noticed that standard kernels found in the fedora repos were built with CONFIG_IRQ_FORCED_THREADING=y thus the kernel parameter threadirqs can be used on boot. To do this I edited /etc/default/grub (with root privileges) such that: GRUB_CMDLINE_LINUX="rhgb quiet threadirqs" and run the following (root) command line grub2-mkconfig --output=/boot/grub2/grub.cfg If this is correct I guess this could be something for the next JAM spin... Using Fernando's tip I get the following listings for version 3.17.4-301.fc21 of kernel.x86_64 bash-4.3$ rtirq status PID CLS RTPRIO NI PRI %CPU STAT COMMAND 487 FF 70 - 110 0.0 S irq/31-snd_hda_ 30 FF 50 - 90 0.0 S irq/9-acpi 51 FF 50 - 90 0.0 S irq/14-ata_piix 52 FF 50 - 90 0.0 S irq/15-ata_piix 58 FF 50 - 90 0.6 S irq/17-ata_piix 65 FF 50 - 90 0.0 S irq/22-ehci_hcd 66 FF 50 - 90 0.1 S irq/20-ehci_hcd 67 FF 50 - 90 0.0 S irq/20-uhci_hcd 68 FF 50 - 90 0.5 S irq/21-uhci_hcd 69 FF 50 - 90 0.1 S irq/20-uhci_hcd 71 FF 50 - 90 0.6 S irq/21-uhci_hcd 72 FF 50 - 90 0.0 S irq/22-uhci_hcd 73 FF 50 - 90 0.0 S irq/12-i8042 74 FF 50 - 90 0.0 S irq/1-i8042 76 FF 50 - 90 0.0 S irq/8-rtc0 252 FF 50 - 90 0.0 S irq/19-yenta 266 FF 50 - 90 0.0 S irq/19-firewire 268 FF 50 - 90 0.3 S irq/29-nouveau 469 FF 50 - 90 0.4 S irq/30-iwl3945 936 FF 50 - 90 0.0 S irq/32-enp9s0 3 TS - 0 19 0.3 S ksoftirqd/0 17 TS - 0 19 0.2 S ksoftirqd/1 bash-4.3$ ps axuw|grep irq root 3 0.3 0.0 0 0 ?
