| astraljava | ScottL: Yeah sure, go ahead. | 01:16 |
|---|---|---|
| holstein | ScottL: yeah... im in | 02:37 |
| ScottL | astraljava, holstein : here is most of steve's instructions: https://wiki.ubuntu.com/SteveConklin/rteval | 03:27 |
| ScottL | here is the rest: "One more thing - it's not clear to me how cgroups might affect this test and the | 03:27 |
| ScottL | validity of the results, so it is probably worth running it both from a terminal | 03:27 |
| ScottL | app under your regular login, and also from the console (ctrl-alt-F1), | 03:27 |
| ScottL | to see whether the results are different" | 03:27 |
| ScottL | thanks astraljava and holstein , i'll do my test tomorrow | 04:04 |
| ailo | ScottL, But we're only supposed to test with a -generic kernel? | 04:04 |
| ScottL | ailo, let me add this part.... | 04:04 |
| ScottL | What I'd like to do now is have just a few people test it and run it on some | 04:04 |
| ScottL | machines (both low-latency and regular kernels) and see whether the numbers it | 04:04 |
| ScottL | gives us are different, make sense, and are useful to us for making judgements | 04:04 |
| ScottL | about the choice between various kernels or options. | 04:04 |
| ScottL | If you can take a look and try to run this under the LL kernel, that would be | 04:05 |
| ScottL | great. If it's useful, I'll see whether I need to put more time into packaging | 04:05 |
| ScottL | this up nicely. | 04:05 |
| ScottL | For now I'll just gather results and compare them. | 04:05 |
| ailo | So you guys have -lowlatency kernels available? | 04:05 |
| ScottL | LL - lowlatency | 04:05 |
| ScottL | abogani's ppa, ailo | 04:05 |
| ailo | I had problems with his kernel | 04:05 |
| ailo | I have my own | 04:05 |
| ScottL | https://launchpad.net/~abogani/+archive/ppa | 04:05 |
| ScottL | oh, what problems were you having? | 04:06 |
| ailo | Are yours working well? | 04:06 |
| ailo | I haven't tried his for a while | 04:07 |
| ailo | I'll install it and see what happens | 04:07 |
| ailo | ScottL, Can't boot with that kernel | 04:30 |
| ailo | I was asking you a couple of days ago about this | 04:31 |
| ailo | Whether we were to be using a different kernel, since alessio has labeled the one in his PPA "old" | 04:31 |
| ailo | Only, the one in his PPA is ahead the Ubuntu kernel by one version | 04:31 |
| ailo | Don't know if that's intentional | 04:32 |
| ailo | I'm using standard Ubuntu install, so I don't know if that will make things any different | 04:32 |
| ailo | I can't even boot into a terminal | 04:32 |
| ailo | ScottL, Could you ask Alessio about this? | 04:33 |
| ailo | I could give you guys a script that would let you build your own custom kernel, but I don't have time to do that today | 04:34 |
| ailo | Heading to the studio later | 04:34 |
| ScottL | ailo, i will ask alessio about it and i'll check one more thing as well | 05:16 |
| ScottL | ailo, try this one perhaps? https://launchpad.net/~abogani/+archive/lowlatency | 05:16 |
| ScottL | you are right, the other one was labeled as "old", this one is just "lowlatency" and latest build was 3 weeks ago | 05:17 |
| ScottL | no headers though in this one :/ | 05:17 |
| ScottL | oh, wait...yes there are header files! | 05:17 |
| ScottL | i think this one is probably the right one then | 05:18 |
| ailo | ScottL, Cool. Se we need to test it on Precise as well then | 05:41 |
| ailo | I heard it was installable | 05:41 |
| ailo | Time to get Precise, then.. | 06:00 |
| len_ | ailo said "I heard it was installable" Close. see my email on the list. There are some metas that have issues. These may not affect this test though. | 06:21 |
| len_ | The install goes fine with no work flows... I was able to install all but 3 of the 6 metas And those three I was able to install most of after the fact with aptitude. The desktop has a problem with the sudo stuff. | 06:25 |
| len_ | When I try to run synaptic for example, instead of asking me for the sudo password, it asks for root's password. Any of the other sudo menu items seemed to have the same problem. | 06:26 |
| len_ | I tested setting up a printer too, same thing. I would guess xubuntu is having this problem too as I don't think we do anything to that. Can someone ask one of them? Seems to me there is someone connected both ways. | 06:28 |
| ailo | As long as we're able to boot into the system. I guess we don't even need a desktop to run the tests | 06:37 |
| ailo | I'm gonna install it this evening (not even 8 am here yet) | 06:43 |
| ailo | And run the test | 06:43 |
| ailo | bb tomorrow about the results | 06:43 |
| len_ | Looking at the instructions a new kernel is downloaded, but no reboot happens? | 06:51 |
| ailo | len_, The instructions for the test? | 06:53 |
| len_ | Ja, the link from earlier on. | 06:54 |
| len_ | This one : https://wiki.ubuntu.com/SteveConklin/rteval | 06:55 |
| ailo | len_, I don't think you install the kernel in those instructions. It seems you download source code into the rtval directory, which is needed for the rtval install | 06:55 |
| len_ | makes sense. I've gotten away from the roll your own days. | 06:56 |
| ailo | I haven't downloaded anything yet, but I assume rtval is compiled and using something from the kernel source | 06:56 |
| ailo | len_, Just install whatever derivative of Ubuntu Precise you want, add abogani's lowlatency and the proceed with the rtval instructions, if you'd like to participate in the test | 06:57 |
| ailo | btw, ScottL: Are there any settings for changing cpu governor in Ubuntu Studio? | 06:59 |
| len_ | I can do that but the machine I have it installed on is using a 40G usb drive. The drive access is kinda slow, would that affect it? | 06:59 |
| ailo | I guess the smartest thing is for everyone to install the same derivative of Ubuntu :P | 06:59 |
| len_ | I've got the nov 18 US on here. | 07:00 |
| ailo | len_, It won't affect audio performance, but I have no idea about what the test does, so.. | 07:00 |
| len_ | I could use 11.10 on the other machine though. | 07:00 |
| len_ | OK, it doesn't look like it has any special needs. I think I will run it on the net book. | 07:02 |
| len_ | It is slower and so will show problems and differences better. | 07:02 |
| ailo | len_, I don't know if it show differences better, or even differently. Atom processor? On our end, we're really just interested in audio performance, but I don't know what the test does yet | 07:04 |
| len_ | Ja atom. Aspire one. | 07:04 |
| ailo | We don't know if the test is useful, even | 07:04 |
| ailo | But, let's get cracking and see what happens :) | 07:05 |
| len_ | Tried rteval on Nov18 alpha distro for US. Step 2D failed: | 07:39 |
| len_ | root@ubuntu:~/python-schedutils-0.3# python setup.py install | 07:39 |

| len_ | python-schedutils/schedutils.c:1:20: fatal error: Python.h: No such file or directory | 07:40 |
| len_ | compilation terminated. | 07:40 |
| len_ | error: command 'gcc' failed with exit status 1 | 07:40 |
| ailo | len_, You're missing something, like a library | 07:43 |
| ailo | len_, I'll have a look at it in the evening or tomorrow | 07:43 |
| ailo | python.h sounds like a standard python dev lib | 07:43 |
| ailo | Belonging to one, I mean | 07:43 |
| len_ | I'm gone for the night. I'll try it on 11.10 tomorrow. | 07:44 |
| len_ | Ya, US seems to be missing a lot of bits... a calader that pops up from the clock would be nice | 07:44 |
| len_ | opps Calendar.. | 07:44 |
| ailo | This would be a development library | 07:44 |
| ailo | Something like python-dev, or similar | 07:45 |
| ailo | See you len_ | 07:45 |
| len_ | bye | 07:45 |
| l33o | mornin every one | 08:23 |
| l33o | bye | 09:09 |
| len_ | G'morning, I would guess that the instructions on the rteval webpage need to be changed to include whatever packages are needed in step one if that procedure is to be useful. | 15:44 |
| len_ | Whoever wrote it probably already had this stuff on their system. | 15:46 |
| astraljava | len_: I fail to see your point. The page starts with "1. Install the required packages:" | 15:47 |
| len_ | Yes, I did straight copy and paste the first line that is supposed to get all required packages sudo apt-get install python-ethtool python-libxslt1 python-dmidecode rt-tests | 15:50 |
| astraljava | And that's not enough? | 15:50 |
| len_ | It didn't work when I get to sudo python setup.py install | 15:51 |
| len_ | See above (last night) for what I got. | 15:51 |
| astraljava | A-ha. Well, you can edit the page, can't you? | 15:51 |
| len_ | At this point if I did that... it would be to add... more stuff required to the page. I am not sure which package it is. | 15:53 |
| astraljava | The thing about wikis, as you can see, is that at any given point in time, they might not be 100% correct. Anything that takes you closer, is welcome. | 15:54 |
| len_ | I came from slackware where all the devel stuff was included in any install I did because a lot of the packages I used where src. Ubuntu is not like that... | 15:54 |
| len_ | Still getting used to it. | 15:54 |
| len_ | Says immutable page, I thought that meant no changes allowed. | 15:55 |
| astraljava | Probably, then. | 15:56 |
| astraljava | Ahh... you just have to login. | 15:57 |
| astraljava | log in* | 15:58 |
| len_ | So I would have to have an account... maybe I do but don't remember :-) | 15:58 |
| astraljava | *rolls eyes* | 16:02 |
| len_ | gotta go for now... | 16:02 |
| ailo | I was going to do the rteval test tonight, but I'm too tired. I'll have to wait until tomorrow | 21:04 |
| ailo | len_, I would start with installing python-dev | 21:07 |
| ailo | len_, Then redo. If there's an error, check what header is missing. Google it, and install the required library | 21:09 |
| shnatsel | I'm writing docs on seeds | 21:26 |
| shnatsel | targeted at creating ubuntu derivatives | 21:27 |
| shnatsel | they might be helpful to you too | 21:27 |
| shnatsel | https://docs.google.com/document/d/1RPPF14h1Sw2gQjGTuZjUIlNHnGrafS8ekhFjJM9MT00/edit | 21:27 |
| shnatsel | trying to make the doc more or less step-by-step | 21:27 |
| shnatsel | any additions, comments, insight etc appreciated | 21:28 |
