| paulg | reading that "workflow" thread (via lore) - had no idea github/lab place so little value on the commit log until I read what kanavin wrote. That seems broken IMHO. Many times the commit log is as important as the change itself. | 03:30 |
|---|---|---|
| paulg | https://lore.kernel.org/all/CANNYZj8_zPhh_XCZrxaPvXd_Oz5kzbzHNLvT6qzvtztquKA0ew@mail.gmail.com/ | 03:30 |
| paulg | Take that cgroup thing that was screwing the LTP runs of the AB for us this summer. It really was just a one line fix. | 03:34 |
| paulg | https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1e7107c5ef | 03:34 |
| paulg | But without that commit log laying out wtf was going on, the change would have been (a) worthless and (b) never accepted. | 03:35 |
| paulg | I want to read stuff in 5-10 years - long after I've forgot what I did, and be able to understand it as if seeing it for the 1st time. | 03:37 |
| jaskij[m] | <paulg> "reading that "workflow" thread..." <- That is true. When looking at a typical GH/GL workflow, you do not look at individual commits in a PR, but rather the whole set of changes. Which then naturally leads to squashing the branch with something more sensible. | 03:38 |
| jaskij[m] | Which is entirely different from a mailing list workflow. In fact, in a mailing list workflow it would make sense to work on a local branch when testing stuff, squash it to a different branch and git-format-patch that for the e-mail | 03:39 |
| paulg | Not sure what you mean by "squash" in this context. | 03:43 |
| jaskij[m] | So you could argue that, so long as the pull/merge commit is fine, the rest is irrelevant (and for a large project, squashes are IMO necessary) | 03:43 |
| jaskij[m] | paulg: Take all the commits in a branch and reapply them on top of master/main as a single new commit. With possibly new commit message. | 03:44 |
| paulg | people do that? Wow. | 03:45 |
| paulg | so you've thrown away the baseline for which the work was developed/tested (which a merge preserves) because you implicitly rebased to a new baseline - AND you throw away any details that the author of the original changes thought were relevant | 03:47 |
| jaskij[m] | My bad. Squash reapplies on the same base | 03:48 |
| jaskij[m] | Just that it replaces all the commits with one | 03:48 |
| jaskij[m] | Also, it depends on how people treat commits. | 03:49 |
| jaskij[m] | Okay, I'm underslept and my mind is in my code. Haven't used squash much so unsure about the rebase | 03:51 |
| paulg | squash in "git rebase -i" context was meant to fold a tweak/fixup into a larger commit. If people are using it to junk all history - well that is just wrong. | 03:51 |
| jaskij[m] | Mhm. OTOH having a clean commit history requires self discipline which I know not everyone has. | 03:54 |
| paulg | again - not following your use of "history" here. | 03:55 |
| paulg | a reference to someone who develops a patch series on a branch already polluted with other non-related changes? | 03:56 |
| paulg | or did you mean "clean commit logs" instead? | 03:56 |
| paulg | either one is easily solved with simple basic and reasonable quality expectations enforced by the maintainer (or sub-maintainer) of the (portion of the) project. | 03:59 |
| jaskij[m] | Clean logs. For me, as the developer, remembering to pause and make a clean commit is something that tears away my focus from the code. So that one commit can cost me a good half hour of work. There are other options - usually involving working out the commits backwards. | 04:01 |
| paulg | sure - nobody says you have to write a three page essay right then and there ; I expect most people might jot a couple key points/words they want to remember and then come and (re)write the logs once they are happy with the code and testing and think it is submit-worthy. That just makes sense. Nobody is suggesting you stop for a half hour and lose focus. Just that you don't get lazy and skip doing them at the end. | 04:04 |
| paulg | Because when you write a commit log, you have to justify the change to others. And if you find you can't do that in a convincing way - well you probably need to go back and take a 2nd look at what you've done. | 04:06 |
| paulg | I'm sure many times that has forced me to re-think things and consider alternate plans and it usually is for the better. | 04:07 |
| jaskij[m] | No argument there. Although, if you're pushing your WIP branch regularly, this does require `git push --force` - something I've mentally marked as forbidden. But that opinion is right now changing, because what is wrong with cleaning up history on a not-yet-merged branch? | 04:09 |
| paulg | most kernel people I've seen (and myself included in that) simply push "feature-ABC-v1" and then "feature-ABC-v2" etc etc. -- unless you've already established with your consumers that there will be a daily non-fast forward reset of a WIP branch (like sfr's next/master for the kernel) | 04:12 |
| paulg | "rules" like no force push need to be understood from why they were recommended in the 1st place and not just blindly adhered to. | 04:13 |
| jaskij[m] | > push "feature-ABC-v1" and then "feature-ABC-v2" | 04:14 |
| jaskij[m] | as in separate branches with different histories | 04:14 |
| jaskij[m] | * > | 04:14 |
| jaskij[m] | push "feature-ABC-v1" and then "feature-ABC-v2" | 04:14 |
| jaskij[m] | as in separate branches with different histories | 04:14 |
| jaskij[m] | paulg: True. And you made me realize that this is one of the rules I've internalized very early on and don't remember the rationale for - if there ever was one. | 04:15 |
| paulg | yes v1 and v2 ;sure. Changed/improved hisory - maybe more commits. And quite possibly different baselines too. Then people can tell you "I was using v1 and it worked fine, but v2 crashes. Unless you are somehow ashamed of the earlier versions, why hide it? | 04:17 |
| paulg | again I'm a kernel person - so typically a feature manages to get "merge worthy" by v5 or so, after absorbing review feedback etc etc - -- assuming it isn't crazy complex | 04:18 |
| paulg | And then it gets *merged* (and NOT REBASED onto master) which preserves the baseline which is CRITICAL for effective use of "git bisect". | 04:20 |
| jaskij[m] | I actually have yet to contribute, unfortunately. There are reasons, but let's not make this discussion about me. Actually, on that topic, is there a way to find some help wanted/beginner issues? | 04:22 |
| jaskij[m] | Because it's been sitting on my mind that I should contribute. | 04:22 |
| paulg | I guess it depends on your area of interest. But the regular yocto status mailout has a paragraph in it that talks about bugs people can pick up if they are looking to get started and helping out. | 04:24 |
| paulg | let me see if I can find a link. Unless someone else here beats me to it. | 04:24 |
| paulg | https://lore.kernel.org/all/066701d7d580$b9390150$2bab03f0$@gmail.com/ | 04:26 |
| paulg | Bottom paragraph "Ways to Contribute". | 04:26 |

| kanavin | paulg, you really haven't used github properly yet? :D man you live in a bubble | 08:36 |
| qschulz | jaskij[m]: if the runtime U-Boot knows about which platform it is booted on, then please go for a fitimage. If not, then check if it's possible to add this detection to runtime (e.g. a GPIO/ADC/whatever). If not, then it depends, you can either build different U-Boots and insert in its environment which dtb to build from the kernel fitimage | 08:46 |
| qschulz | tlwoerner: I switched to honister/master for now, I'll get back to dunfell once I have something for you. Turns out mailine UBoot is half broken for us :| (depends on the toolchain being used...) | 08:47 |
| qschulz | tlwoerner: but while you're here, our board ha U-Boot proper at a different offset in the storage medium, why do we have two reserved partitions between the SPL (idbloader.img) and U-Boot proper in the wks? | 08:48 |
| *** zpfvo <zpfvo!~fvo@89.244.125.164> has quit IRC (Ping timeout: 250 seconds) | 08:49 | |
| qschulz | paulg: what I also don't like about GitHub CI is that it does builds/tests on the last commit of the pull request (or the last commit after a push). Or at least in the "default" configuration (i'm new to github ci). | 08:50 |
| jaskij[m] | qschulz: What is wrong with going fitimage build time? ie, not one fitimage with two dtbs, but two different fitimages each with one of the dtbs. Hardware detection is unfortunately not possible, as it's the same baseboard with different SoMs. It is slightly hacky, but at least I keep everything in my BSP layer instead of in U-Boot. | 08:50 |

| qschulz | paulg: also... yes, I've heard some projects squash many commits together *on purpose*. git commit logs are surprisingly really not cared about. and it's hard to force people to write good ones. | 08:52 |
| qschulz | jaskij[m]: you can have an Image.gz in there, I think U-Boot just detects it's compressed and uncompresses it before trying to load it | 08:52 |
| JosefHolzmayrThe | qschulz: s/force/cluebat/g | 08:52 |
| qschulz | paulg: how does this branch-v1, branch-v2 works for github/gitlab based PR? Is there a way to make a PR use a different branch after it's been opened? | 08:53 |
| jaskij[m] | qschulz: I know I can, the question is how to tell Yocto to use Image.gz in fitImage. | 08:53 |
| *** Bardon <Bardon!~Bardon@user/Bardon> has joined #yocto | 08:54 | |
| qschulz | Granjow: if you have the new overrid syntax, you should have FILES:${PN}:append and do_install:append. if you have the old syntax, FILES_${PN}_append and do_install_append | 08:54 |
| jaskij[m] | qschulz: another hacky way, if the pins are otherwise unused, I can just use the DT with the WiFi and let the probe fail. | 08:54 |
| qschulz | jaskij[m]: what is different between the SoMs? U-Boot is running on the Som, not the carrierboard :) | 08:55 |
| jaskij[m] | WiFi | 08:55 |
| jaskij[m] | there's two SoM variants, one includes a CYW-based WiFi | 08:55 |
| jaskij[m] | they're otherwise identical | 08:55 |
| jaskij[m] | but U-Boot needs to know which DT to pass to the kernel | 08:56 |
| qschulz | Usually you have a way to distinguish HW at runtime based on HW configruation. If not, tell your HW dept to do it next time :) | 08:56 |
| jaskij[m] | "HW dept" - we're small enough that I do all the pinouts for SoMs :P | 08:57 |
| qschulz | jaskij[m]: one way would be to init the SDIO (I assume it's SDIO) card for the WiFi and read the SDIO_DEVICE_ID and SDIO_MANUFACTURER_ID and base your choice of dtb from there | 08:57 |
| qschulz | jaskij[m]: resistors populated or not on an ADC input pin is one way to do this, allows for a big amount of configurations to be described | 08:58 |
| qschulz | jaskij[m]: having two different fitimages just because you have two different dtb is not really using the benefits frm fitimages :) (almost using it as if it was a uImage :D) | 08:59 |
| jaskij[m] | I thought fitImages replaced uImages? | 08:59 |
| jaskij[m] | I'll verify with the EE, but it seems those SDIO pins are unused - so yes, I can probe, or just use the same DT and let the kernel probe fail | 09:00 |
| qschulz | jaskij[m]: I meant the WiFi module is connected to SDIO | 09:00 |

| qschulz | also..... I think you might be able to have one kernel with two SDIO devices in the SDIO controller device tree node | 09:01 |
| qschulz | because it matches against the SDIO_DEVICE_ID and SDIO_MANUFACTURER_ID to know which driver to probe | 09:01 |
| qschulz | so if your power-up sequence (mmc-pwrseq) is the same for both (same pins, same timings), you can do that | 09:02 |
| jaskij[m] | it's.... a stupid SoM design - the WiFi module is on the SoM and connected to the SoC, but at the same time signals are present on the SoM connector so you can use them if using a no-WiFi variant | 09:02 |
| qschulz | jaskij[m]: yeah it's not really important to know what;s going out of the SoM, you want to know what';s on the SoM (I assume nothing changes on the carrierboard?) | 09:03 |
| jaskij[m] | the other device tree, if it ever uses those pins, won't be using those pins for SDIO | 09:03 |
| jaskij[m] | (SoM is external btw) | 09:04 |
| jaskij[m] | and yes, carrier is the same | 09:04 |
| qschulz | tlwoerner: well... that's new :p especially since atf is not in a separate partition but in U-Boot | 09:05 |

| qschulz | jaskij[m]: Not that I know no. I mean you can always modify the files from your U-Boot sources to adapt them. Otherwise, I think you could have different uEnv.txt or boot.scr files per board and use this as boot script and keep the U-Boot binary identical for both SoMs | 09:38 |

| qschulz | tlwoerner: I don't think you're going to like the question but... our board is not yet migrated to TPL and it is an issue for Yocto-built SPL apparently because its size seems to be a bit too much for the SoC to handle it correctly | 11:21 |
| qschulz | it's not an issue with fedora35 or debian11 aarch64, hence why it's news to us | 11:21 |

| jaskij[m] | If only docsis allowed more upstream channels | 11:46 |
| kanavin | jaskij[m], it does in the latest standard, but operators are slow to introduce it | 11:46 |
| kanavin | it also requires discontinuing analog TV | 11:46 |
| jaskij[m] | The only times I've seen analog cable TV in my life was with stolen signal | 11:47 |

This technology enables multi-gigabit symmetrical services while remaining backwards compatible with DOCSIS 3.1. CableLabs released the full specification in October 2017." | 11:47 |

| jaskij[m] | Yeah. And the best hotel in town has quite a bit of history behind it. | 11:49 |

| qschulz | and now I cry with Austrian ISPs speed | 11:53 |
| kanavin | the thing is, how do you even saturate a 1Gb link at home | 11:53 |
| kanavin | there's only so many 4K videos a typical household can watch at the same time :) | 11:53 |

| qschulz | I'm more upset by upload link, it's not nice when you have your server at home :/ | 11:55 |
| kanavin | and if you can buy 8k monitors for all family members, you won't be doing 'yocto' ;) | 11:55 |
| qschulz | kanavin: you don't need 8k monitors to select 8k quality on the Youtube player :p | 11:56 |
| kanavin | but you still need a computer that can handle it :) | 11:57 |
| qschulz | details, details | 11:57 |
| kanavin | but seriously. I wonder what Nvidia is going to do when they reach real time ray tracing with resolutions that exceed human eye ability. | 11:58 |
| jaskij[m] | kanavin: One of my main points during my autumn PC upgrade was to have my Gbit downlink be the bottleneck when downloading from Steam. TBH, I only went Gbit because ISP told me the upgrade from my legacy 300 Mbit plan was an euro a month. | 11:58 |
| kanavin | jaskij[m], same here, I convinced my ISP to give me a promo deal which is meant for new subscribers only, so I'm paying the same price I did before, and first 6 months are free :) | 11:59 |
| jaskij[m] | kanavin: There's new techniques and papers coming out all the time to make stuff more realistic looking. I know a dev working on one of the major offline 3D engines and reading papers is a significant part of his work. | 12:01 |
| kanavin | I'm slightly anxious about the flood of deep fake videos this will enable | 12:03 |
| kanavin | hopefully people will learn that a video is not to be trusted | 12:03 |
| jaskij[m] | kanavin: I just called them up, we were shuffling some hardware and needed a new settop. Then the call center dude just offered it. | 12:04 |

| rburton | 0.60 means we can drop a bit from insane.bbclass, which pleases me | 12:37 |

| rburton | which is mostly deleting code too, so yay | 12:39 |
| kanavin | webkit has a bizarre patch submission process. Every patch is an attachment in bugzilla, and there's an in-tree script that creates a bug, and attaches the patch to it.

| RP | jsbronder: seems quite strange it would only happen with openssl as that shouldn't be large enough to cause issues with threads/memory with 96GB avail | 19:32 |
| RP | jsbronder: would be interesting to strace a failing run and see if you can see anything odd about the trace | 19:32 |
| jsbronder | I have to take it back about it running in parallel, setting RPM_BUILD_NCPUS=1 seems to have resolved things for me. | 19:35 |
| jsbronder | The strace didn't have anything of interest, in particular I was looking for EINVAL. But the only failing calls were some ENOENTs, mostly rpmbuild looking for config files and a couple of EAGAINs. | 19:37 |
| RP | jsbronder: did you hit the max open files limit? | 19:37 |
| RP | jsbronder: rpm is quite different between dunfell and master now :/ | 19:38 |

| RP | sometimes the new toys have sharp edges too | 19:39 |
| khem | RPM_BUILD_NCPUS=1 tells me a rpm bug | 19:41 |

| Pan5ky | does anyone have experience using dotnet with bitbake? my recipes build fine when i build them individually but when i run them in parallel the dotnet process trips up and is stuck at project restore. | 20:08 |

| *** hpsy <hpsy!~hpsy@user/hpsy> has quit IRC (Quit: Leaving.) | 21:28 | |
| RP | vd: usually your distro or *something* should be controlling it | 21:30 |

| RP | vd: yes | 21:35 |
| vd | ok then I guess it's up to you to add the layer knowing that it'll make such customization, thus you must adjust the BBFILES_PRIORITY accordingly for that customization layer | 21:36 |
| RP | vd: the point is that you have to opt in to the customisations by selecting the distro | 21:37 |
| vd | RP: ok I see. I was pushing the customization too far because I want to customize my images for specific customer, so I was adding an override for it. But I understand that a meta-customer layer would be more appropriate. | 21:41 |

| moto-timo | vd: those layers might be very trivial, just a distro layer to house the psplash customization. just a BSP layer to add device tree. The extra directories/git repos eventually seem to make life easier. | 22:07 |
