| OvenWerks | Eickmeyer: FYI - http://www.ovenwerks.net/paste/kernel.txt | 15:29 |
|---|---|---|
| * OvenWerks also wonders what the difference is... | 15:30 | |
| Eickmeyer | OvenWerks: Did you explain that USB requires that buffer be 128*3? | 15:32 |
| OvenWerks | The conversation makes it clear they are trying to monitor through the DSP and need low latency. | 15:33 |
| OvenWerks | however, the main point is that one kernel works and another doesn't. | 15:33 |
| OvenWerks | https://liquorix.net/ | 15:33 |
| Eickmeyer | Ok, well, I don't see any solution from our perspective. The kernel team would have to modify the configs, or accept a MP from us on the existing lowlatency config. | 15:34 |
| OvenWerks | This is actually maintained by one of the xubuntu devs ;) | 15:34 |
| Eickmeyer | brb | 15:34 |
| OvenWerks | (or at least is mirrored by) | 15:40 |
| OvenWerks | Anywy, I am also not sure if we should try changing our lowlat kernel or merely be ready to mention "other" possibilities. | 15:45 |
| wonko | I should give it a go and see what happens | 15:45 |
| wonko | It's only 5.2 currently it seems (if that really matters) | 15:46 |
| OvenWerks | So long as it works with your HW that should be ok. | 15:46 |
| wonko | I don't see why it wouldn't. 5.0 worked | 15:47 |
| wonko | ok, reboot time. :) | 15:47 |
| OvenWerks | right. | 15:47 |
| OvenWerks | one of the great lines one their web page is: "Tunes the kernel for responsiveness at the cost of throughput and power usage" | 15:48 |
| wonko | I wonder what that actually means. 😁 | 15:51 |
| OvenWerks | Eickmeyer: certainly we have not kept the lowlatency kernel up to date with the newer kernels | 15:52 |
| OvenWerks | wonko: low latency != speed | 15:52 |
| wonko | I understand that | 15:53 |
| wonko | But I wonder what they do to achieve that | 15:53 |
| Eickmeyer | OvenWerks: I recently went over the config, and it's still quite sane and not much different from the default one. The lowlatency kernel is now maintained by the Ubuntu Kernel team, not us. | 15:53 |
| Eickmeyer | Though, I know they'll accept any sane MP we throw at them. | 15:53 |
| OvenWerks | Eickmeyer: yes they maintain it... effectively for us but the config started here. | 15:54 |
| Eickmeyer | Might be good to compare the liquorix kernel's config file to the lowlatency one and see if we can simply bring-in that config and see if we can merge request it into the lowlatency kernel. | 15:54 |
| Eickmeyer | Who's the Xubuntu dev that is involved? | 15:55 |
| wonko | Ugh, it didn't set grub correctly and booted into lowlatency instead | 15:55 |
| OvenWerks | Maybe not anymore, his web page no longer points at it. | 15:55 |
| wonko | so, that's a fail. :) | 15:55 |
| Eickmeyer | Ok. | 15:56 |
| Eickmeyer | Who *was* it then? | 15:56 |
| OvenWerks | it was unit193 | 15:56 |
| Eickmeyer | Oh! | 15:56 |
| Eickmeyer | Well, we already have a relationship with him, might be worth talking to him. | 15:57 |
| Eickmeyer | teward: ping | 15:57 |
| OvenWerks | if you look at the "Debian Prerequisites:" on https://liquorix.net/ and scroll through... it still shows his site as a mirror | 15:57 |
| Eickmeyer | I see. | 15:58 |
| wonko | that should have put something in /etc/grub.d/ right? | 15:58 |
| wonko | that's how grub works these days? | 15:58 |
| OvenWerks | you would probably have to look in the sub menu | 15:58 |
| wonko | I........ don't know what that means. :) | 15:59 |
| OvenWerks | right under the lowlatency entry (or generic if you have one there is another entry... I don't remember what it is called) that when select gives another menu | 16:00 |
| wonko | There was advanced options and custom I think were the two other options | 16:00 |
| OvenWerks | advanced options I think. | 16:01 |
| wonko | You would think a kernel installing itself would make a grub boot option though, no? | 16:01 |
| OvenWerks | no. | 16:01 |
| wonko | This thing is such a hassle to reboot. Ugh. | 16:01 |
| OvenWerks | What is the kernel actually called? | 16:01 |
| wonko | vmlinuz-5.2.0-21.2-liquorix-amd64 | 16:02 |
| OvenWerks | with ls -l /boot what date does it show for that kernel? | 16:03 |
| wonko | -rw-r--r-- 1 root root 8939392 Oct 17 19:12 vmlinuz-5.2.0-21.2-liquorix-amd64 | 16:04 |
| wonko | it's smaller. I wonder what they've cut out then? | 16:04 |
| OvenWerks | hard to know. Maybe some of the non-free blobs? | 16:05 |
| OvenWerks | (wifi, nvidia, etc.) | 16:06 |
| OvenWerks | Eickmeyer: That kernel may not be great for graphics, or video... in fact the low latency kernel may not be the best either | 16:07 |
| OvenWerks | Eickmeyer: I think we should be adding the generic kernel to installer | 16:08 |
| Eickmeyer | OvenWerks: Yeah, and possibly the seed. | 16:08 |
| wonko | Ok, I don't think I'm going to mess with that right now. I've got things to actually do other than wait for my computer to reboot. :) | 16:09 |
| OvenWerks | :) | 16:09 |
| OvenWerks | wonko: new upload, last_master gets initialized for first start (to "") and device detection doesn't try to do anythinig if jack is False | 18:22 |
| OvenWerks | wonko: the GUI is different as well but can mostly be ignored. It still works but there are some new bits that do nothing right now. | 18:24 |
| wonko | ok, i'll click on them a lot and complain to you that they don't do anything. :) | 18:24 |
| wonko | in the configparser branch, right? | 18:24 |
| OvenWerks | in master | 18:24 |
| wonko | have you merged configparser yet? | 18:25 |
| OvenWerks | configparser is finished/ready for delete | 18:25 |
| wonko | groovy | 18:25 |
| wonko | gui doesn't look any different to me. :) | 18:27 |
| OvenWerks | did you put it in the right place? | 18:28 |
| OvenWerks | usr/share/ubuntustudio-controls/ubuntustudio-controls.glade has to be put in it's place | 18:29 |
| wonko | oh right, I forgot that part | 18:42 |
| wonko | I was just copying usr/bin/* to /usr/bin/ | 18:42 |
| wonko | WHY DOESN'T CHECKBUTTON DO ANYTHING?!?!?!?! YOU'RE TERRIBLE AT THIS!!!!!!!!one!!!!! | 18:44 |
| wonko | :D | 18:44 |
| OvenWerks | Actually I just removed that... | 18:44 |
| OvenWerks | Now it works ;) | 18:44 |
| OvenWerks | wonko: I have left the top part for now but my intent is to have two sides, inputs and outputs with the left being inputs and the right being outputs. | 18:45 |
| wonko | I definitely like the layout changes | 18:45 |
| wonko | the tabs make it less cluttered | 18:45 |
| wonko | yeah, that would be a nice change | 18:46 |
| OvenWerks | the top will have a drop down (on each side) with the list of bridges plus the bottom one will be "Add Bridge" | 18:46 |
| wonko | also, no more jack getting restarted since i started using the configparser version (with your changes to that) | 18:46 |
| wonko | so that's happy times | 18:46 |
| OvenWerks | then there will be a name slot to set the name | 18:46 |
| OvenWerks | then a connect to slot | 18:47 |
| OvenWerks | wonko: I am not sure if I should allow a number of channels or not... but whtever | 18:47 |
| wonko | We'll figure it out. :) | 18:48 |
| OvenWerks | I want to do something similar for "Extra Devices" | 18:49 |
| OvenWerks | Probably not connections though | 18:49 |
| OvenWerks | I want to have a USB device blacklist for things like webcams | 18:51 |
| teward | Eickmeyer: ERR:bronchitis | 23:17 |
| teward | Is the ping urgent? | 23:18 |
| Eickmeyer | teward: Nah, it was a general discussion. | 23:18 |
| teward | Ah. Context? | 23:18 |
| Eickmeyer | Scrolling... | 23:18 |
| teward | Since i just napped for 7 hours I am actually half sane lol | 23:18 |
| Eickmeyer | teward: It had to do with changing the config in the lowlatency kernel. Mostly merge requests and what-not. | 23:19 |
| teward | Ah. All kernel config changes have to go through the Kernel team | 23:19 |
| Eickmeyer | That's what I thought. | 23:19 |
| teward | Because thats their realm | 23:20 |
| teward | They need to spotcheck, etc | 23:20 |
| teward | Test | 23:20 |
| teward | The whole shebang | 23:20 |
| Eickmeyer | Yeah. We used to directly maintain the lowlatency kernel directly, aiui. | 23:20 |
| teward | I wouldnt want to make any config changes default either without their input as well | 23:20 |
| Eickmeyer | Right. | 23:20 |
| Eickmeyer | It would be to more closely match the Liquorix kernel since that does a better job of handling audio. If we did that, we'd also seed the generic kernel. | 23:21 |
| teward | This is why I lurk #ubuntu-kernel lol | 23:21 |
| Eickmeyer | I also lurk there. | 23:21 |
| teward | Eickmeyer: i would wonder the diff between the existing kernel and the Liquorix kernel. | 23:21 |
| Eickmeyer | teward: Yeah, that's something I'd need to research. | 23:22 |
| teward | Also consider that AIUI all kernels get Main and Security coverage so it is a larger discussion | 23:22 |
| teward | About support for multiple seeded kernels, etc. | 23:22 |
| Eickmeyer | OvenWerks: ping | 23:22 |
| teward | @Eickmeyer: if the config changes for lowlatency make sense I think Kernel team would be more than happy to work with you to get them in. | 23:25 |
| Eickmeyer | teward: Right. I'll have to check the diffs. | 23:25 |
| teward | I think that it would be a NACK on shipping more than one kernel base version tho | 23:25 |
| teward | My thoughts nothing to substantiate rho | 23:26 |
| teward | Tho* | 23:26 |
| teward | Darn phone... | 23:26 |
| Eickmeyer | Well, it's always the same kernel base version as generic, so that shouldn't be an issue. | 23:26 |
| teward | I meant if you went and asked them to also ship Liquorix just for Studio ;) | 23:27 |
| teward | But yes otherwise the base is still the Generic that is already maintained by Kernel. | 23:27 |
| Eickmeyer | No, I wouldn't want to do that. I'd want to take their config and figure out the diff for our existing lowlatency kernel and figure out what makes the most sense. | 23:28 |
| teward | Unrelated I have been floored for 3 days >.< bronchitis is evil | 23:28 |
| teward | Had to use PTO... | 23:28 |
| Eickmeyer | Dude, bronchitis is from Hell itself. | 23:28 |
| teward | Pneumonia is worse | 23:28 |
| Eickmeyer | That's true. Pneumonia knocked me on my back a couple years ago. | 23:29 |
| teward | As long as the bronchitis doesnt evolve into lower respiratory hell i will be fine | 23:29 |
| Eickmeyer | Yeah. Typically it doesn't, but that would definitely be bad. | 23:30 |
