| szlin | toscalix: Do you have any idea on it ? | 09:02 |
| patersonc | hi | 09:03 |
| toscalix | no, this is a topic for the maintainers | 09:03 |
| toscalix | I just pinged bwh | 09:03 |
| toscalix | no answer yet | 09:03 |
| szlin | oops, that's bad. Because the next topic is also related to him | 09:04 |
| toscalix | agree | 09:05 |
| toscalix | I see the release mail at 22:10 | 09:06 |
| toscalix | I wonder if he is up | 09:06 |
| toscalix | anyway, let's move on. I will talk to him later on | 09:06 |
| toscalix | to find out what happened | 09:06 |
| moxavictor | hi | 09:06 |
| szlin | The topics which I have are related to him, so let's have open discussion? | 09:07 |
| patersonc | szlin: I have a question | 09:08 |
| szlin | please | 09:08 |
| patersonc | Can you outline the experience your team has with Linux and Linux maintenance? | 09:09 |
| szlin | sure. | 09:10 |
| szlin | The team is made up by volunterrs in different departments | 09:11 |
| moxavictor | hi everybody, i am new guy in this chat, may i know others ? | 09:11 |
| toscalix | moxavictor: yes, but we are in the middle of a meeting, so what about later on? | 09:11 |
| moxavictor | ok, i join this meeting from moxa | 09:12 |
| toscalix | cool | 09:12 |

| szlin | Wes/ Ethernet driver | 09:12 |
| toscalix | quite a team | 09:13 |
| patersonc | Great :) | 09:13 |
| szlin | We are developing the industrial products, so it needs long-term support in Linux | 09:13 |
| toscalix | o/ | 09:13 |
| patersonc | Which Kernel version do you tend to use at the moment? And do you actively upstream? | 09:13 |
| szlin | For example: rail way, power station and marine | 09:14 |
| szlin | The same as the CIP kernel 4.4 | 09:14 |
| szlin | patersonc: yes, "upstream first". | 09:15 |
| patersonc | Great | 09:15 |
| szlin | And of course, it's the spirit of open source | 09:15 |
| toscalix | o/ a couple of points from me | 09:16 |
| toscalix | may I? | 09:17 |
| szlin | by all means. | 09:17 |
| toscalix | #info New gitlab subgroup for kernel repos: https://gitlab.com/cip-project/cip-kernel | 09:17 |
| toscalix | #link https://gitlab.com/cip-project/cip-kernel | 09:17 |
| toscalix | Feel free to use the journal. It helps us to keep track of the work. | 09:18 |
| toscalix | #link https://wiki.linuxfoundation.org/civilinfrastructureplatform/journal | 09:18 |
| toscalix | The third point is a question: Is there anybody at Moxa who will use B@D to test the kernel? | 09:18 |
| moxavictor | toscalix: could i know where you from ? | 09:18 |
| toscalix | I work for codethink | 09:19 |
| moxavictor | good | 09:19 |
| szlin | toscalix: moxavictor is our kernel guru, he works in Moxa for more than 25 yrs | 09:19 |
| *** patersonc has quit IRC | 09:19 | |
| *** patersonc has joined #cip | 09:20 | |
| szlin | toscalix: yes, we are trying to do this test by aligning with our testing system | 09:20 |
| toscalix | can I ask what do you guys use? | 09:20 |
| toscalix | for testing I mean | 09:20 |
| * patersonc is back (poor network connection) | 09:20 | |
| szlin | patersonc: Are you Chris from Renesas? | 09:21 |
| patersonc | szlin: Yep | 09:21 |
| szlin | toscalix: Do you mean testing tool ? | 09:21 |
| toscalix | yes, for the kernel | 09:21 |
| szlin | We used Jenkins/ Lava | 09:21 |
| toscalix | ah, LAVA, then we will be able to collaborate easily | 09:21 |
| toscalix | even if you use plain LAVA on a server we will be able to share the configs, tests, etc | 09:22 |
| moxavictor | toscalix: the testing need hardware, how do you get hardware to do it ? | 09:22 |
| toscalix | rajm: Robert Marshal is the person working on it | 09:22 |
| szlin | That's exactly what we doing | 09:23 |
| toscalix | moxavictor: we are using the CIP platforms: BBB and the Renesas board | 09:23 |
| rajm | yes it would be good to have more content to the tests within lava - very much on the surface at the moment | 09:23 |
| szlin | moxavictor: I think he used BBB/ Renesas board for testing | 09:23 |
| rajm | (am also from Codethink) | 09:23 |
| moxavictor | can you add moxa's board to do it ? | 09:24 |
| toscalix | moxavictor: we can, but adding platforms has many implications in terms of maintenance, and involve costs, so there is a process to propose new platforms | 09:24 |
| toscalix | there should be a formal proposal to the TSC | 09:25 |
| rajm | That would be a good addition - we're still integrating the renesas config | 09:25 |
| rajm | ah ok | 09:25 |
| moxavictor | ok, i got it | 09:25 |
| patersonc | rajm: I've been told that Renesas will add to the LAVA tests at some point, not sure when though sorry. | 09:25 |
| toscalix | Technical Steering Committee. I suggest you guys go through it | 09:25 |
| rajm | :-) | 09:25 |
| toscalix | like Renesas did | 09:25 |
| patersonc | moxavictor: Do you already have a Renesas board? | 09:25 |
| szlin | toscalix: thanks for guiding | 09:25 |
| moxavictor | no, we used others SoC | 09:26 |
| patersonc | moxavictor: Okay. If you or your team need Renesas board(s) to help with the CIP maintenance then please let me know. Perhaps we can get some to you. | 09:27 |
| moxavictor | patersonc: tks | 09:27 |
| toscalix | the same applies to Moxa with the rest of the members. If Moxa wants other Members to use their platform, send boards is the usual approach | 09:28 |
| szlin | patersonc: Do you also want to join CIP kernel maintenance team? | 09:28 |
| toscalix | once it becomes an official platform | 09:28 |
| toscalix | we would use it | 09:28 |
| toscalix | One last point from me: talked to bwh yesterday about putting the kernel configs on the wiki | 09:29 |
| moxavictor | toscalix: you mean that we can send board to CIP ? | 09:30 |
| patersonc | szlin: It's an option I'm trying to push for, but struggling atm. Renesas is a silicon provider and historically we don't tend to get involved directly with Kernel maintenance. | 09:30 |
| toscalix | to members, yes. Renesas sent us a board and now we are working with it to supoprt it with B@D | 09:30 |
| szlin | moxavictor: If we send the proposal and get approved in TSC, yes | 09:31 |
| moxavictor | ok, got it | 09:31 |
| toscalix | the idea is to test the cip kernel on the CIP platforms | 09:31 |
| moxavictor | may i know patersonc where from ? | 09:32 |
| toscalix | back to my last point, bwh and I will workl on it the coming days | 09:32 |
| patersonc | moxavictor: I'm based in Renesas' UK office | 09:32 |
| moxavictor | welcome | 09:32 |
| patersonc | szlin: Can I ask what distro(s) do you use? | 09:33 |
| szlin | Debian | 09:33 |
| toscalix | szlin: is debian dev, correct? | 09:33 |
| szlin | patersonc: Actually, I am DD | 09:33 |
| szlin | toscalix: correct. | 09:34 |
| toscalix | patersonc: szlin is one of the DebConf 2018 organisers | 09:34 |
| patersonc | Ah :) | 09:35 |
| patersonc | So super Deb then | 09:35 |
| patersonc | Do you plan to use CIP Core / Deby? | 09:35 |
| szlin | Since Debconf18 will be held in Taiwan | 09:35 |
| toscalix | SDD :-D | 09:35 |
| szlin | patersonc: we do not use yocto or meta-debian. | 09:36 |
| szlin | we develop our tool for image generation | 09:36 |
| *** patersonc has left #cip | 09:37 | |
| *** patersonc has joined #cip | 09:37 | |
| moxavictor | who know the kernel maintainer do what ? | 09:37 |
| toscalix | we are over 7 min from the scheduled time. I need to go | 09:37 |
| toscalix | next week again. I will tell bwh to ping you guys when he is back, through IRC | 09:38 |
| szlin | :( please ping bwh and let he know our topics afterwards | 09:38 |
| patersonc | toscalix: Thanks | 09:38 |
| toscalix | so you can ask him the questions that were a matter of this meeting | 09:38 |
| moxavictor | ok, bye, tks | 09:38 |
| szlin | thanks | 09:38 |
| patersonc | szlin: Are you using CIP Core / Deby at all? | 09:38 |
| szlin | patersonc: We don't use Deby but our own tool | 09:39 |
| patersonc | Okay. What are your platforms based on? ARM? | 09:39 |
| szlin | yap | 09:39 |
| patersonc | armhf/arm64? | 09:40 |
| szlin | https://www.moxa.com/product/UC-8100-ME-T.htm | 09:40 |
| szlin | patersonc: Both | 09:40 |
| patersonc | Okay | 09:40 |
| patersonc | Sorry for all the questions :) | 09:41 |
| szlin | patersonc: Are you a kernel engineer in Renesas? | 09:41 |
| szlin | do not worry about it | 09:41 |
| patersonc | Yes, I am a member of the Linux team in the UK and I manage the technical side of the CIP project for Renesas. | 09:42 |
| moxavictor | patersonc: what you will do ? | 09:42 |
| moxavictor | bug fix ? add new driver ? new kernel version porting ? | 09:43 |
| szlin | I met katayama-san last year in OSS-J | 09:43 |
| patersonc | moxavictor: At the moment we are concentrating on upstreaming support for the Renesas RZ/G1 SoCs and platforms and then backporting them to the CIP Kernel | 09:43 |
| patersonc | szlin: Great. Katayama-san is the overall project lead. I work with him closely. | 09:44 |
| szlin | patersonc: I see. | 09:44 |
| patersonc | moxavictor: With this in mind I'm keen to collaborate as much as possible with the CIP maintenance team to smooth the process. | 09:44 |
| patersonc | Renesas are also looking to contribute to the testing side of the project, especially the CIP-RT side. The plan is to get a LAVA-lab setup to facilitate this. | 09:45 |
| szlin | patersonc: Which subsystem do you often to work with? | 09:45 |
| patersonc | szlin: Most of our work is adding new platform support so I touch a little on a lot of subsystems rather than being an expert on one. | 09:46 |
| moxavictor | the Linx RT patched needs to fix some device driver, do you do it ? | 09:46 |
| patersonc | moxavictor: Most of the RT work is done by the RT project. At the moment we're just consumers of their work. The demo we showed at ELC is based on the CIP-RT branch. | 09:47 |
| szlin | patersonc: Kernel generalist. | 09:48 |
| patersonc | :) | 09:48 |
| patersonc | Alas I'm not signing up for the CIP maintenance though ;) At the moment I have no time :( | 09:48 |
| moxavictor | ok | 09:49 |
| patersonc | I have little maintenance experience anyway! But happy to keep in the look and learn. | 09:49 |
| patersonc | s/look/loop | 09:49 |
| szlin | patersonc: same here :) | 09:49 |
| patersonc | As you're an expert, can I ask you about Debian maintenance? | 09:50 |
| szlin | By all means, if I can answer it | 09:50 |
| patersonc | During debian-stable, what is maintained? Just security fixes? Or bug fixes etc. as well? | 09:51 |
| szlin | patersonc: Most of them are security-related stuff, some of them are critical "rc" issue | 09:54 |
| szlin | This point release mainly adds corrections for security issues, along with a few adjustments for serious problems | 09:55 |
| szlin | ref: https://www.debian.org/News/2018/20180310.en.html | 09:55 |
| patersonc | Okay. And this maintenance is done for all of the Debian packages? | 09:56 |
| patersonc | szlin ^ | 09:59 |
| szlin | Be right back, got a meeting at 18:00 | 09:59 |
| patersonc | szlin: Okay! | 10:00 |
| patersonc | szlin: Some other questions whilst I remember them: I assume that Debian LTS _only_ backports security fixes. Is this for all packages or just a sub-set? Do you know if Debian LTS will support ARM64 for Jessie? | 10:03 |
| patersonc | bwh: Perhaps questions for you ^ | 10:35 |

| patersonc | Ah :( | 12:27 |
| Ystk | have you discussed something about kernel maintener? | 12:28 |
| patersonc | We did. Agustin sent round a log of the conversation to cip-dev | 12:29 |
| szlin | Ystk: Not so much, since Ben was not here | 12:29 |
| Ystk | that nice. I thought we should discuss about in the morning 🙁 | 12:30 |
| Ystk | I see | 12:30 |
| Ystk | we... CIP have to find someone to take over the roll. | 12:31 |
| szlin | patersonc: AFAIK, they have no plan for Jessie in ARM64 support | 12:32 |
| Ystk | for myself, I am not aware with Arm64 support for Jessie | 12:32 |
| patersonc | szlin: Thank you. Do you know if there is a plan for LTS support in future Debian releases? | 12:32 |
| Ystk | but Moxa want to do, maybe. | 12:33 |
| szlin | Ystk: we are focus on Stretch | 12:34 |

| Ystk | Yes, I am Yoshi here | 12:35 |
| szlin | Ystk: Hiii!! | 12:35 |
| szlin | patersonc: Unsure, but I think ARM64 is trend. just a matter of time | 12:37 |
| patersonc | szlin: Thanks. I'm just trying to plan ahead. If CIP is using Debian because of the DebianLTS support, we need to make sure it supports the architectures we are using. | 12:38 |
| szlin | Ystk: Will CIP sponsor OSS this year? | 12:38 |
| szlin | patersonc: BTW, the discussion here will be recorded | 12:38 |
| Ystk | I agree it is trends. but imho, for arm 64 we can focus on the next kernel release | 12:39 |
