[01:39] Anyone know about usb interrupts? I show 5 interrupts for usb1 to usb5. I have 6 usb ports(plugs)... all of which seem to use usb1. usb1 is ehci (usb 2.0) and usb 2 to usb 5 are uhci (usb1.1 I think) [01:43] The MB manual does not show any other usb pins. Odd... anyway, USB seems to be my high priority interrupt. [01:45] eth0 was sharing the same interrupt, but I moved it to be lower than my audio cards and have my ice1712 higher than the ensoniq. [01:49] So far it seems stable. I'm running Audacious through PA->jack at -p 64, downloading software and can run some midi stuff at the same time with no xruns. [02:36] astraljava, todays respin seems to work well live/installed on both my desktop and my netbook and I have marked the i386 as passed in both live and install. [03:38] len-dt: Excellent news, thank you for your efforts! :) [03:41] astraljava, whens the next respin? [03:41] I don't know, hopefully there is none. :) [03:42] I'll sniff the air on -release and let you know if something's happening. [03:42] astraljava, lots activity in #ubuntu-release... [03:42] Heheh, yeah I do fear so... [03:43] Well anything during the last 12 hours doesn't seem to touch us, so thus far I doubt there's going to be a new one on Sunday. But there's still plenty of time left for that. :) [03:45] release day/hour=? [03:51] 26th. [03:51] Why oh why oh why can't people read anymore? [03:52] No offense to whoever that dude is, but I explained all that in the original email. [03:52] Apparently it was a case of TL;DR. [03:52] grr [03:55] astraljava, hey, if he has an amd64, maybe it will get done and then he will know for next time. [03:56] Yeah. :) [03:57] I'd have to start studying how one creates installer packages for Macs. But I think I'll try and get a few more hours of sleep, first. [04:04] Bah, Mail.app doesn't seem to play very nicely together with Gmail. [06:49] len-dt: usb should be no problem as long as you don't use it [06:50] I haven [06:50] 't tried messing with mine, but I have share ir's with usb ports and they aren't affecting performance for me anywyay [06:51] wifi and graphic card are commone to cause problems [06:51] With the initirq script, shared irq is supposed to be less of a problem, but I'm not so sure [06:52] I don't know if we have got any confirmation on this, when it comes to -lowlatency [06:53] As I've said before, I don't think you can trim general performance by tuning either the desktop or the kernel [06:53] If you get problems, they are most probably hardware related [06:54] By tuning the kernel, I mean by switching things off. Of course, the low latency stuff is what matters [07:24] len-dt: If you like, try disabling the initirq scriptto see how that affects your performance. It's a dependency to -lowlatency, so what I did was I just moved /etc/init.d/rtirq [07:29] len-dt: Also, use "ps -eo rtprio,pri,ni,comm" to see the difference in rtprio for your processes [07:29] You'll need to reboot in between, of course [14:32] ailo, sorry I had gone to bed (not beauty sleep, just non-ugly sleep) [14:33] I found that my pci slots starting right after the video slot go from low to high. [14:36] The last one is int 23, but is shared with all the usb2.0 ports. I had the nic in there for that reason, but I found out that hardware wise it has priority... so net traffic affected my sound. [14:38] I have moved the nic to beside the video card... it gets int17 now. [14:42] The end slot where it was is empty to avoid int sharing with a sound card and the one next to that (int 22?) still had the knockout so I left it empty too for now. Next is the ice1712 with int 21. It seems to be rock solid now... -p32 is possible with the odd xrun, but -p64 only gets xruns when PA's jacksink closes a port... not jack's fault and not a good low latency use anyway. [14:50] next the ice1712 is the ens1370 with int20. It gets used for midi io only and the audio part just causes trouble. [14:50] * len-dt wishes he could turn that part off and just get midi. [14:53] I have to make sure I turn it off in PA after a new install or it can cause xruns... maybe not so much now that the int is lower priority. [14:57] I have found that turning off pulse->jack bridging brings cpu usage down a lot in -p128 and lower. Try: [14:57] pactl unload-module `pactl list short |grep jackdbus |sed s/module-jackdbus-detect//` [14:58] To test this. and pulseaudio --kill to restart. [15:02] At -p1024 the effect doesn't show, but lower, PA's CPU goes up about twice as fast as jacks. [15:11] I have turned off the par and ser ports in bios and found out I have ir and firewire (also turned of) as well. [15:16] ailo, ps -eo rtprio,pri,ni,comm, gives this: [15:16] 85 125 - irq/20-snd_ens1 [15:16] - 19 0 dnsmasq [15:16] 85 125 - irq/21-snd_ice1 [15:17] should I be running the ens at 80? [15:18] also I have: [15:18] 80 120 - irq/23-ehci_hcd [15:18] 80 120 - irq/16-uhci_hcd [15:18] 78 118 - irq/19-uhci_hcd [15:18] 79 119 - irq/18-uhci_hcd [15:18] 79 119 - irq/16-uhci_hcd [15:18] But with no usb devices that should not be a problem. [15:50] I will try testing with that stuff turned off to see what difference it makes [16:28] ScottL meeting today? [16:29] len-dt, we were supposed to [16:29] we still can [16:29] i'm doing a few errands around the house but i'll poke in quite often and see if we reach a quorum for a meeting [16:36] ScottL, I have to go in the next few minutes. [16:42] So you guys come up with a schedule. I'll probably go to sleep within the next couple of hours, so if it happens during that time, I can participate. [16:43] But we seriously have to commit to meetings better the next cycle, [16:43] It's been rather ridiculous for the current one. [16:43] astraljava, ja, no kidding [16:44] I get the idea people are not yet ready to talk about next cycle, being worn out from this one. [16:45] len-nb: Yeah, and it's why I'm not trying to squeeze anyone for best times for it, yet. [16:45] Let us all cool down for a moment. :) [16:46] astraljava, I think so, also maybe the time change may confuse people. [16:47] I have gone from -9 to -8 [16:47] Yeah. But then it also seems this current schedule isn't the most optimal. [16:49] Anyway, I have to go. [18:29] * astraljava laughs at the mail on -users [18:29] Is someone actually working on the Preparation page? [18:30] We should remove the "under construction" statement if not. [18:35] astraljava, i believe ttoine was doing it [18:37] Ok. === jussi is now known as android
