[LAD] rtirq script is broken with 2.6.31

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Rui et al, I just found that recent kernel development (merging IRQ threads into mainline) breaks the "rtirq" setup script. Basically rtirq does nothing. The command to get the PID PIDS=`ps -eo pid,comm | egrep "IRQ.${IRQ}\$" | awk '{print $1}'` (rtirq line 120) does no longer work since the IRQ process names have changed. I've quickly changed it to PIDS=`ps -eo pid,comm | egrep "irq\/${IRQ}-" | awk '{print $1}'` and it sets the priorities again, but that's not correct since it also raises priority of other drivers on the same IRQ.. Similarly `rtirq status` returns nothing. I've checked with: `ps -ewo pid,class,rtprio,ni,pri,pcpu,stat,comm --sort -rtprio` instead. It looks like a new set of regexps for rtirq is in order ;) This is Linux soyuz 2.6.31-rc5-rt1.1 #1 SMP PREEMPT RT Wed Aug 5 23:06:21 CEST 2009 i686 GNU/Linux # ps -eo pid,comm | grep -i irq 4 sirq-high/0 5 sirq-timer/0 6 sirq-net-tx/0 7 sirq-net-rx/0 8 sirq-block/0 9 sirq-tasklet/0 10 sirq-sched/0 11 sirq-hrtimer/0 12 sirq-rcu/0 149 irq/9-acpi 495 irq/14-ata_piix 496 irq/15-ata_piix 506 irq/16-yenta 526 irq/12-i8042 527 irq/1-i8042 1418 irq/8-rtc0 1428 irq/19-ehci_hcd 1446 irq/16-uhci_hcd 1447 irq/17-uhci_hcd 1450 irq/18-uhci_hcd 1452 irq/19-uhci_hcd 1544 irq/29-iwl3945 22591 sirq-high/1 22592 sirq-timer/1 22593 sirq-net-tx/1 22594 sirq-net-rx/1 22595 sirq-block/1 22596 sirq-tasklet/1 22597 sirq-sched/1 22598 sirq-hrtimer/1 22599 sirq-rcu/1 22609 irq/17-HDA Inte 22610 irq/17-ohci1394 22952 irq/16-i915@pci 22968 irq/28-eth1 Yes I'm also baffled at the high PIDs for IRQs. I hazard a guess that those are a result of a suspend/resume cycle; and I'll check later if the chrt settings do persist after a suspend/resume. so long, robin
