Re: [linux-audio-user] Re: Frustrated bigtime

Well, I upgrated to 13-rc6 and tried the patch. The patch ruins the kernel source...it won't compile on this architecture (amd64) with it applied. However, it seems to be included to some degree already. There are only 3 preempt modes and I chose the best...the one I wanted to try first anyway. I also fixed the IDE driver issues. I haven't even messed with any of the interupts. It is working...for now at least. I even started mozilla in the middle of a playback to test and I didn't get an xrun. I did get 2 while typing this and they were not small ones. I am also wondering if it might be some acpi setting I could change that would help a lot. For instance: localhost CPU1 # cat power active state: C2 max_cstate: C8 bus master activity: 000021eb states: C1: type[C1] promotion[C2] demotion[--] latency[000] usage[00000010] *C2: type[C2] promotion[C3] demotion[C1] latency[090] usage[30301282] C3: type[C3] promotion[--] demotion[C2] latency[900] usage[00014940] Maybe switching to C1 could help? I'm assuming latency should be smaller... I also can't seem to find out which interrupt my soundcard is on. I don't see it in the list: localhost proc # cat interrupts CPU0 0: 318085 IO-APIC-edge timer 1: 3765 IO-APIC-edge i8042 8: 0 IO-APIC-edge rtc 9: 1694 IO-APIC-level acpi 12: 1170 IO-APIC-edge i8042 14: 6163 IO-APIC-edge ide0 15: 12 IO-APIC-edge ide1 177: 29479 IO-APIC-level SiS SI7012 185: 519 IO-APIC-level eth0 193: 15025 IO-APIC-level ohci_hcd:usb1 201: 0 IO-APIC-level ohci_hcd:usb2 209: 0 IO-APIC-level ohci_hcd:usb3 217: 54 IO-APIC-level ehci_hcd:usb4 NMI: 1088 LOC: 318053 ERR: 0 MIS: 0 And what is the proc file interface for the preempt patch?
