| thomas_34 | https://docs.yoctoproject.org/dev-manual/building.html?highlight=multiconfig#building-a-simple-image Chapter 4: "The target is the name of the recipe you want to build." | 06:28 |
| thomas_34 | https://docs.yoctoproject.org/dev-manual/building.html?highlight=multiconfig#building-images-for-multiple-targets-using-multiple-configurations : "You can use a single bitbake command to build multiple images or packages for different targets where each image or package requires a different configuration (multiple configuration builds)." | 06:29 |
| thomas_34 | I'm confused here. "Target" in the first definition means cleary something different compared to the second sentence. | 06:29 |
| ablu | thomas_34: In the first example "target" references to the "bitbake <target>" above. | 06:33 |
| thomas_34 | ablu, ahh okay. So when I want to communicate with "yocto-people", what do they understand under the term "target"? | 06:34 |
| ablu | thomas_34: Typically it is your build result. What that is probably depends on your context. | 06:36 |
| thomas_34 | Okay, so its not the "piece of hardware", which I build software with yocto/bitbake? | 06:37 |
| ablu | I would call it "piece of software built for a particular configuration (hardware, tunable, ...)". But I am not sure whether one will be able to find a definition that fits everything. | 06:40 |

| Ad0 | I have a working defconfig, but I want to change it into fragments | 09:38 |
| Guest40 | Good all, I am trying to create a yocto, which has two recipes, one "mount-points" which does the mount of the disks, and in the other one I want to create a directory and add a file to that directory "utilities.bb", in "utilities.bb" I have specified with RDEPEND that "mount-points" must be executed first so there is no conflict with | 09:40 |
| Guest40 | "utilities.bb" but I am not able to create the directory after the mount. | 09:40 |
| Guest40 | I have tried to create the directory in / instead of in the disk I am mounting and it has worked without problem so I understand that the recipe works fine and the problem is that it will try to mount later and it will step on the directory that is created with "utilities.bb". | 09:40 |

| landgraf | Ad0: https://docs.yoctoproject.org/kernel-dev/common.html#preparing-the-build-host-to-work-on-the-kernel | 09:44 |
| Ad0 | that's in the layer, not the working dir | 09:45 |
| Ad0 | my idea is to remove the defconfig from my layer and let it use the vanilla config, then replace the config in the working directory so it will be created as a fragment when done | 09:46 |
| Ad0 | easier to see what's different so I can remove the shit I don't need | 09:47 |
| landgraf | Ad0: The document I linked covered this task iirc | 09:47 |
| Ad0 | I don't think it covers the internals like where the config ends up in the working tree | 09:48 |
| Ad0 | I need to find that path and replace the file | 09:48 |
| landgraf | Ad0: iiuc you want to have vanila defconfig + fragments in your layer, right? | 09:49 |
| Ad0 | yes, but I already have a "complete" modified defconfig in my layer already. when I start the task it will use that file . but I will temporarily remove the file and rather replace it in the working tree so a fragment is created | 09:50 |
| Ad0 | with several devices with different defconfigs + kernel upgrades I think fragments would be easier | 09:50 |
| Ad0 | instead of full defconfigs per device | 09:51 |
| Ad0 | also it will remove some bbappend scripting | 09:51 |
| landgraf | Ad0: just run find tmp* -name .config in your builddir and you'll find it | 09:51 |
| Ad0 | yeah from memory last time I checked there were several | 09:52 |

| Ad0 | could be | 09:53 |
| Ad0 | I will just try a -c menuconfig and diff the files till I find one that matches | 09:53 |
| landgraf | there're several but not all are related to kernel. | 09:53 |
| Ad0 | thanks! I think the path you have there is correct | 09:58 |
| enok71 | Anyone who knows how kernel-fitimage.class works and how to make it create config sections that u-boot can actually use to add a bunch of .dtbo overlay images included in the fitimage file to the included .dtb image at boot time, as described in the u-boot documentation? It looks to me like those config sections emitted by kernel-fitimage are not entirely useful for u-boot. I'm using the latest master HEAD from the poky git repo. | 10:03 |
| Ad0 | landgraf, does it generate fragments for me based on the diff from menuconfig? | 10:05 |
| Ad0 | the article you gave me seems like i have to manually make my own | 10:05 |
| Ad0 | maybe I didn't read well enough | 10:05 |
| Ad0 | bitbake -c diffconfig virtual/kernel | 10:06 |
| enok71 | Or perhaps nobody uses dtbo in this way and instead creates multiple complete .dtb files and no .dtbos? A waste of space though, as 99% of such dtbs will be identical. | 10:08 |
| rburton | merit: do the apply_sysroot_patches as a postfunc on do_patch. because patch runs before configure and DEPENDS is short-hand for do_configure[depends] you'll need to add the dependency on the other recipe explicitly. | 10:11 |
| Ad0 | "Could not locate BSP definition for my-machine/standard and no defconfig was provided" but it is based on raspberry pi tho. | 10:12 |
| Ad0 | probably because I set MACHINEOVERRIDES | 10:16 |
| rburton | by default the yocto-kernel framework uses MACHINE as KMACHINE | 10:21 |
| rburton | if you're not providing a bsp definition then make sure you set KMACHINE to the right one | 10:21 |
| Ad0 | thanks | 10:22 |
| Ad0 | that var is nowhere in meta-raspberrypi tho | 10:23 |
| Ad0 | something else sets that maybe | 10:23 |
| rburton | as i said, default is MACHINE | 10:23 |
| rburton | https://git.yoctoproject.org/poky/tree/meta/classes-recipe/kernel-yocto.bbclass#n17 | 10:23 |
| Ad0 | thanks a lot | 10:24 |
| Ad0 | so you can set a different machine for kernel | 10:25 |
| Ad0 | it worked setting it to it but I guess I have to find the right name ... Could not locate BSP definition for raspberrypi3/standard and no defconfig was provided | 10:26 |
| rburton | have you created a new machine that pulls in the rpi machine? | 10:26 |
| Ad0 | no, just require conf/machine/include/arm/armv7a/tune-cortexa7.inc and include conf/machine/include/rpi-base.inc | 10:27 |
| rburton | meta-raspberrypi doesn't even use linux-yocto, so you either need to use the meta-rpi kernel, or provide your own config | 10:28 |

| Ad0 | ok | 10:28 |
| Ad0 | I will just copy the defconfig from the linux-raspberry pi and use that as a baseline. what sucks is that I have to think about updating that too | 10:29 |
| rburton | the rpi kernel pulls the rpi fork of linux which has a defconfig in | 10:30 |
| Ad0 | yeah | 10:30 |
| rburton | use that :) | 10:30 |
| Ad0 | linux-raspberrypi/1_5.15.92+gitAUTOINC+509f4b9d68_14b35093ca-r0/defconfig | 10:31 |
| Ad0 | so if I use git pull on that layer I might have to update it | 10:31 |
| rburton | recipes-kernel/linux/linux-raspberrypi.inc:KBUILD_DEFCONFIG:raspberrypi4 ?= "bcm2711_defconfig" | 10:31 |
| rburton | if you use their kernel tree then you can just use the defconfig it provides | 10:31 |
| Ad0 | maybe I can set the KBUILD_DEFCONFIG in my bbappend for my machines then? | 10:32 |
| rburton | if you have rpi hardware then i don't know why you don't just use the rpi kernel in meta-rpi, but yes you could recreate the recipe | 10:33 |
| Ad0 | I seen that name but not gotten into it (meta-rpi) , not sure what the diff is between that and meta-raspberrypi | 10:34 |
| rburton | i was being lazy, meta-raspberrypi is what i meant | 10:34 |
| Ad0 | yeah I have seen some alternate layer for meta-rasperrypi | 10:34 |
| Ad0 | I use the kernel there but | 10:34 |
| Ad0 | setting KBUILD_DEFCONFIG in my bbappend worked | 10:37 |

| paulbarker | Hey folks, here's something I've not thought about before but came up in discussions today - should we be providing an older linux-libc-headers version if our BSP provides a kernel version older than the one in oe-core? | 14:20 |
| Guest84 | Nothing else to change but the python3_blah.bb file? | 14:21 |
| paulbarker | E.g. Scarthgap will have linux-libc-headers 6.6, but our BSP will use the 6.1 CIP kernel by default | 14:21 |

| Guest84 | Let me try that and I’ll come back to you | 14:21 |
| Guest84 | rburton: Thanks | 14:22 |
| paulbarker | https://docs.kernel.org/kbuild/headers_install.html explicitly says that "Kernel headers are backwards compatible, but not forwards compatible." | 14:22 |
| rburton | zeddii: ^^^ | 14:22 |
| paulbarker | My reading of that is that we should be providing the older linux-libc-headers version in our BSP and using it when we build an older kernel | 14:22 |
| zeddii | it's been stated that way for years. in practice, we've hit a grand total of zero issues. | 14:25 |
| zeddii | I'd be strongly against any changes in core to the headers, but people can do whatever they want in their own layers. | 14:25 |
| paulbarker | zeddii: We definitely don't need any changes in core. | 14:27 |
| zeddii | my opinion stands on any layer, but I just obviously have no input on them. | 14:28 |
| paulbarker | I expect issues would occur if someone used flashy new kernel features that weren't present in our older BSP kernel, but adoption of new APIs/etc is usually slow | 14:28 |
| zeddii | if you change the libc-headers, you are then repsponsible for the complete testing of all your applications and there's not much OEcore or any maintenance can do if you run into an issues. | 14:28 |
| zeddii | paulbarker: and that's a pathalogically evil program that is going directly at kernel headers and structures. if something goes through libc, they are well protected. | 14:29 |
| zeddii | this is very well trodden ground. | 14:29 |
| zeddii | (the libc-headers question) | 14:29 |
| zeddii | I answered it about 13 years ago at Wind River, and the answer still hasn't changed. | 14:29 |
| paulbarker | zeddii: From that I imply that Go is pathologically evil, and I don't disagree haha | 14:29 |
| zeddii | indeed! | 14:30 |
| *** sev99 <sev99!~sev99@172-100-114-080.res.spectrum.com> has joined #yocto | 14:30 | |
| RP | paulbarker: keep in mind that linux-libc-headers works in conjunction with glibc and the toolchain to decide what to do. glibc has the notion of "OLDEST_KERNEL" and the "guarantees" are also from components like glibc. | 14:32 |
| RP | paulbarker: you really don't want or need multiple toolchains and libc-headers versions around | 14:34 |
| RP | paulbarker: as zeddii says, whilst you may not have considered it, it has been given a lot of thought and real world testing over the last decade+ | 14:35 |
| paulbarker | So, the conclusion would be - libc provides enough of a buffer to prevent issues | 14:40 |
| zeddii | the only class of applications that even have a chance of running into issues are exchanging structures with the kernel AND if the kernel for some reason decided to re-order a structure. The userspace ABI promise is in play, regardless of what libc-headers says. | 14:43 |
| zeddii | if something is that tied to the kernel, you'd hope that same application is checking the version, etc. | 14:43 |
| jdiez | when modifying (with `devtool modify`) a build tool that is required by another recipe, is it enough to do `devtool build <buildtool>`? the changes I made don't seem to be visible when I build the recipe that depends on this build tool | 14:44 |

| pbiel | I'm a bit confused abut how should I approach the following problem in Yocto. | 17:45 |
| pbiel | For example I have a machine and I would like to achieve the following: | 17:45 |
| pbiel | for development builds I would like to use extlinux configuration and store let's say 10 different device tree blobs on /boot partition to allow switching between them on boot for the purpose of some tests | 17:45 |
| pbiel | on the other hand for the same machine for a production build I would like to add some patches to u-boot that remove all the unnecessary u-boot commands and leave only bootm command, the same goes for the image type I would like to use for the production build - fitImage and what's more signed | 17:45 |
| pbiel | Basically this can be applied to more use cases, not only u-boot. | 17:45 |
| pbiel | Whenever I searched for the answer to this question, most answers concerned the image generation where the solution is simple - just create two image variants: *dev, *production, and install appropriate packages accordingly. But this cannot be applied as things like kernel device tree, uboot config and so on are configured in machine file. | 17:45 |
| pbiel | What is the canonical solution for such problems? | 17:45 |

| khem | pbiel: I would say, define new distro_features dev and prod and make the needed changes under those since the changes are not only in recipe space but also global namespace | 18:05 |

| pbiel | Well that makes sens actually. I'm looking at this moment at the ATF recpipe for one of NXP's boards, and in fact, in that recipe they change if DISTRO_FEATURES contains secure. If so they use UBOOT_BINARY that is preconfigured to support secure boot, otherwise they use standard u-boot config | 18:09 |
| pbiel | they check* | 18:10 |

| Zapados | How do I layer kas YMLs? For example, parent.yml has some BBLAYERS ?= in it. Then I want child.yml, header: includes: -parent.yml, then append some more BBLAYERS in there. Any way to do that? | 20:24 |
| jonmason | Zapados: we're doing it in meta-arm | 20:24 |
| jonmason | there is an include method | 20:24 |
| jonmason | one sec and i'll link you | 20:24 |
| jonmason | Zapados: https://git.yoctoproject.org/meta-arm/tree/ci/qemuarm.yml | 20:25 |
| Zapados | jonmason I don't see that extending BBLAYERS though. | 20:26 |
| vvn | hi there -- I have an ERROR: No recipes in default available for: <paths-to-dynamic-multimedia-layer>/libcamera_%.bbappend, but I do have meta-multimedia in my BBLAYERS. Any idea what could be the issue? Layers order or priority maybe? | 20:26 |
| jonmason | Zapados: I thought you were generally asking how to layer them | 20:27 |
| jonmason | you can see in base.yml how to change variables | 20:27 |
| jonmason | https://git.yoctoproject.org/meta-arm/tree/ci/base.yml | 20:27 |
| jonmason | that is what is included in that qemuarm.yml file | 20:28 |
| jonmason | and we tweak it further in testimage.yml | 20:28 |
| jonmason | and in xen.yml | 20:28 |
| *** vladest <vladest!~Thunderbi@adsl-89-217-204-83.adslplus.ch> has quit IRC (Quit: vladest) | 20:28 | |
| jonmason | then you just do something like "kas build ci/qemuarm.yml:ci/xen.yml:ci/testimage.yml" | 20:28 |
| Zapados | jonmason looking at testimage.yml, what additional layers are added there? It's likely I'm thinking about this wrong...? | 20:31 |
| jonmason | if you want layers, xen.yml pulls in meta-virt | 20:31 |

| jonmason | essentially, you are modifying the local.conf via the tag "local_conf_header:" | 20:32 |
| Zapados | jonmason so to extend BBLAYERS I could do something like BBLAYERS:append = " test"? | 20:33 |
| Zapados | Ahh, this was stacking: | 20:34 |
| Zapados | bblayers_conf_header: | 20:34 |
| Zapados | meta-xxxbase: | | 20:34 |
| Zapados | LCONF_VERSION = "7" | 20:34 |
| Zapados | BBPATH = "${TOPDIR}" | 20:34 |
| Zapados | BBFILES ?= "" | 20:34 |
| Zapados | layer-order: | | 20:34 |
| Zapados | BBLAYERS ?= " \ | 20:34 |

| jonmason | you only need the secondary names if you are going to override them in another yml | 20:43 |
| jonmason | but that looks like it might work | 20:43 |
| Zapados | i'd like to extend them, not override. Say there are 30 BBLAYERS entries in first YML. Second YML needs to add 2 more layers. I just want to extend the list by the 2 more. | 20:44 |
