Hi, I'm trying to use my firewire cards (Alesis IO14 and Yamaha GO46) for recording my saxophone over a previously recorded session with Ardour and I'm unable to do it because I experiment xruns more often that it should be no matter which interface I use.. I get xruns even when not playing/recording music. I'm using FFADO trunk version and Jackd 1.9.7 (QJackCTL with default settings). The strange thing is I'm able to do it with an EMU 0404 USB (which is supposed to be more prone to xruns than a firewire interface) with 0 xruns. As I mention in the subject I get xruns in both 2 distros (Mandriva and Fedora) so I guess it's an IRQ issue but I'm unable to follow this guide: http://subversion.ffado.org/wiki/IrqPriorities This is what I get: ... cat /proc/interrupts CPU0 CPU1 0: 125 9 IO-APIC-edge timer 1: 4 4032 IO-APIC-edge i8042 4: 0 4 IO-APIC-edge 8: 0 1 IO-APIC-edge rtc0 9: 0 0 IO-APIC-fasteoi acpi 12: 953 182082 IO-APIC-edge i8042 14: 0 0 IO-APIC-edge pata_atiixp 15: 0 0 IO-APIC-edge pata_atiixp 16: 0 1 IO-APIC-fasteoi ohci_hcd:usb2 17: 1 44 IO-APIC-fasteoi ohci_hcd:usb3, ohci_hcd:usb5 18: 356 103082 IO-APIC-fasteoi ohci_hcd:usb4, ohci_hcd:usb6, radeon 19: 30 5586 IO-APIC-fasteoi ehci_hcd:usb1 20: 146 65627 IO-APIC-fasteoi firewire_ohci 21: 2 92 IO-APIC-fasteoi ICE1724 22: 335 142664 IO-APIC-fasteoi ahci 41: 195 85324 PCI-MSI-edge eth0 NMI: 0 0 Non-maskable interrupts LOC: 964322 1031999 Local timer interrupts SPU: 0 0 Spurious interrupts PMI: 0 0 Performance monitoring interrupts PND: 0 0 Performance pending work RES: 607534 426798 Rescheduling interrupts CAL: 1645 1509 Function call interrupts TLB: 9531 6635 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts MCE: 0 0 Machine check exceptions MCP: 9 9 Machine check polls ERR: 0 MIS: 0 ps -eLo pid,cls,rtprio,pri,nice,cmd | grep -i "irq" 3 TS - 19 0 [ksoftirqd/0] 7 TS - 19 0 [ksoftirqd/1] 5476 TS - 19 0 grep --color=auto -i irq I have no chance to know each IRQ priority and/or modify it.

This is still kind of experimental. If you encounter problems, please also check with the old stack. ... The problem is I can't use the old stack with Fedora current kernel. Things get better (but not perfect) if I use the CCRMA RT kernel but I should be able to do it with the regular kernel. My firewire card has the TI chipset. Your help will be really appreciated. Thank you in advance, Luis Pablo |
