<Sion> Hello everyone, I'm fairly new with Yocto (love it atm). I do have a question regarding the tested distribution list, I'm currently using Debian Bullseye in combination with the latest hardknott and I don't see any immidiate issues but is the Yocto team currently testing Debian 11 as well?
<JosefHolzmayrThe> Sion: i have no definitive statement on that, but i'm pretty sure it will get into the autobuilder testing in some not-too-distant future.

<fbre> (replace with your account names and passwords)

camus has joined #yocto
<fbre> JosefHolzmayrThe: I did not install specific useradd/groupadd stuff for the account which runs the image generation
<JosefHolzmayrThe> fbre: no, but i guess that your image brings those and therefore they at least end up in the sysroot, right?
<fbre> JosefHolzmayrThe: It's not an account which needs root rights
<JosefHolzmayrThe> fbre: no, thats not what i'm talking about.
<JosefHolzmayrThe> anyways, i'll give your approach a spin and check if there are different effects.
<JosefHolzmayrThe> nope, perfectly the same.
<fbre> JosefHolzmayrThe: Which error does happen?
<JosefHolzmayrThe> fbre: i con't copy it out at the moment, but upon inspection there is no useradd/usermod in the -native sysroot. hence, it fails. so i guess my real question is: what form of dependency do i need for that tool to show up.
<fbre> JosefHolzmayrThe: I don't know what you mean with "in the -native sysroot"...
<JosefHolzmayrThe> fbre: your EXTRA_USERS_PARAMS needs the usermod command to be available. unless specific actions are taken, my understanding is that it will be taken from the -native sysroot for the recipe in question (in this case, the image)
<JosefHolzmayrThe> fbre: and if the command is not there, it cannot be executed.
<fbre> What is a "sysroot" and what is its property "-native"
<fbre> ?
<fbre> Sorry, can't help further
lucaceresoli has joined #yocto
<JosefHolzmayrThe> fbre: sysroots are the environments that are created per recipe, basically from the dependencies. and the -native incarnation is the one thats meant to run during the build. no problem, i know its a complicated problem.
mihai has quit [Quit: Leaving]
<JosefHolzmayrThe> qschulz: looks like shadow should provide it.
<fbre> What is "shadow" in this case?
Schlumpf has joined #yocto
<fbre> ah OK, likely I use another package which draws "shadow" in then
<qschulz> JosefHolzmayrThe: extrausers IMAGE_CLASSES does not include that bbclass I think?
<RP> JosefHolzmayrThe: You'd not expect it to show up in the native sysroot, you'd expect it to be in the target one?
<JosefHolzmayrThe> RP: -native one.
<JosefHolzmayrThe> and as it inherits useradd, i'd naively expect it to pull in all things needed for... "adding users" :)
<RP> JosefHolzmayrThe: I think I'm misreading the above, I thought you mean the user/group wasn't in the native sysroot. You're right that the tools should be added
<JosefHolzmayrThe> RP: exactly, but it seems that this is not the case.
<RP> JosefHolzmayrThe: for your demo recipe, you could put a chown call in the do_install
<JosefHolzmayrThe> RP: to get rid of the dummy?
<qschulz> JosefHolzmayrThe: also, FILES:${PN} :)
<RP> JosefHolzmayrThe: no, just that you're not using the user/group you're creating anywhere
<JosefHolzmayrThe> RP: lemme try.
<RP> JosefHolzmayrThe: it won't change anything much but it would fail if there was an issue
<JosefHolzmayrThe> RP: yeah thought so.
<JosefHolzmayrThe> why doesn't FILES_${PN} err out on parsing?
<RP> JosefHolzmayrThe: it can't know that is an override. It only errors on "_append" which it knows is bad
<JosefHolzmayrThe> ah.
<JosefHolzmayrThe> but DEPENDing on neither shadow-native nor shadow-sysroot seem to give me the commands
<JosefHolzmayrThe> wCPO: whenever you want to run something during build time.
<wCPO> JosefHolzmayrThe: Make sense, but why does it have libtpm-native then?
<JosefHolzmayrThe> wCPO: no idea, look at the recipe to see what it needs. it might also be something that its build process relies on inside.

davidinux has joined #yocto
<RP> wCPO: sometimes these things persist when they're no longer needed
<wCPO> RP: yep, I'm gonna CC the guy who updated it in the past when I submit the patch, maybe he know
<sveinse> If I specify "bitbake -k packagegroup-something package-index" will a) package-index be run even if packagegroup-something fails and b) will it execute last?
<rburton> yes, no
<sveinse> ok, thanks
<rburton> (they'll execute in parallel)
<sveinse> package-index on its own invocation step then, got it
<rburton> you can try https://github.com/rossburton/meta-ross/blob/master/classes/simplefeed.bbclass and see if you can make it work properly
<rburton> oh no, not that
<rburton> huh where is my class
<sveinse> Yeah, the use case is that we're building to a packagefeed, but occational not every package compiles successfully, so in order to have a valid package feed, I'd like to update the repo I've got
<sveinse> Normally bitbake packagegroup-x does this if and only if it completely succeeds
<rburton> i had a patch that would run package-index in the closing stages of the build so you could always have an up to date feed, but i appear to have lost it
<RP> rburton: you've lost it? :)
<rburton> i lost it long ago
<RP> rburton: I suspect we all did...

<JosefHolzmayrThe> great minds think alike, they say.
<sveinse> Is there a yocto/bb-way of disabling a systemd service in a ROOTFS_POSTPROCESS step? For those services that has been installed with systemd.bbclass and have a system-preset/98-*.preset entry
thekappe has joined #yocto
<sveinse> I'm not sure how the preset logic actually work. Something in (yocto) first time startup activates the presets and thus enables/disables these services?
leon-anavi has quit [Quit: Leaving]
<qschulz> to be done in the recipe providing the systemd service
<sveinse> qschulz: Yes. And say the bb enables a service via these mechanisms, but then the image wants the service disabled. Whats the right way of doing that?
<qschulz> I assume proper way would be a bbappend for that bb, or a distro. For the hackish way, looking at how it is done by the systemd class and call the same things from within the rootfs might do it
<sveinse> Is .bb the right spot? I mean the recipe/package might be correct, but multiple images might want different enable/disables. Then I'd need a separate bbappend for each of those image variants, right?
<qschulz> that's policy and policy is what the distro is responsible for
<qschulz> otherwise you can always try to run `systemctl disable <service name>` in your ROOTFS_POSTPROCESS_CMD but it does not feel super right
<jaskij[m]> Does anyone have a link or something with arguments I could use to allow my boss to open source my recipes?
<RP> jaskij[m]: I'm not sure we have anything written into the docs. michaelo, do you know anything?
<RP> jaskij[m]: I did write https://lists.yoctoproject.org/g/yocto/topic/82722441? is which different but related
<rburton> jaskij[m]: if they're recipes for relatively common software then the best argument is that other people will test/maintain. if you get a recipe into meta-oe for example then other will also help keep it up to date

<sveinse> qschulz: I see. Under the yocto paradigm, a distro handles policy, that all good. It would then imply that you'd need multiple distros to make different policies, or startup policies, like in this case, wouldn't it? Doesn't that make it, uhm, a big machine for an image variant? Or is that how yocto distros are?

<jaskij[m]> if I'm looking right, it somehow goes through `PACKAGECONFIG` variable flags and uses the values of the flags that are listed in the base variable?
<jaskij[m]> is this normal, or is this something that comes from one of the classes inherited?

<qschulz> 5.4, 5.10, probably 5.16?
<jaskij[m]> earlier it was every fifth iirc
<jaskij[m]> 5.4 to 5.10 was the exception
<jaskij[m]> but who knows?
<jaskij[m]> so long it makes it into Yocto 3.5 ;)
<qschulz> 4.4, 4.9, 4.14, 4.19 indeed
<rburton> fabatera[m]: DEPENDS += "autoconf-archive" is exactly what you want
<perdmann> qschulz: https://dpaste.org/1CYd
<perdmann> so i really broke that :-D
<qschulz> perdmann: BBLAYERS is a space separated list of paths :)

<qschulz> perdmann: with bitbake -e you have the history of the variable, so you can see where all gets messed up
<jaskij[m]> qschulz: I'm still angry at my SoM vendor - outdated imx-sc-fw means I'm stuck at 4.14 :/
<fabatera[m]> rburton: Thank you! I was wondering if the dependency could be auto generated. (It was not needed on previous Yocto zeus release).
<rburton> no
<rburton> build dependencies are explicit
<qschulz> perdmann: have you also triple checked that you have the correct branch checked out for all your layers and Bitbake (if you use openembedded-core without poky)?
<qschulz> otherwise, noidea.gif and I'm now afk so good luck :)
<qschulz> jaskij[m]: sc-fw?
<qschulz> jaskij[m]: imx SoCs support in upstream kernel is very good usually
<perdmann> qschulz: wait what do i use? ...
<jaskij[m]> qschulz: Might've misnamed. The firmware for the built-in M4 in i.MX8X. It must much the sec firmware, and one of the two is causing issues with the kernel if I try 5.4.
tnovotny has quit [Quit: Leaving]
<jaskij[m]> afaik they wrote that firmware against pre-mainline kernel released by NXP

<sveinse> jaskij[m]: I am too. We're stuck at rocko due to some vendor opengl driver. I'm sure there is newer kernel+yocto combos that work, but its quite the validation work. Dunfell/Gatesgarth/Hardknott has too new systemd for the kernel
<jaskij[m]> oof
<jaskij[m]> I at least was able to port the kernel and firmwares to Dunfell, might not be fully validated but seems to work nicely
<jaskij[m]> sveinse: if you're using i.MX, afaik there's a reverse-engineered OpenGL driver for the VCG which has perf parity with the closed source one
<sveinse> jaskij[m]: yes, the etnaviv - it's the same. However there are some GL operations etnaviv doesn't support. E.g. dithering is not great in etnaviv so the UX team put the veto foot down
<jaskij[m]> and I really don't want an older systemd than what's in Dunfell, I really want the nice CAN support in systemd-networkd
<sveinse> wait what, does systemd support operations from CAN?
<jaskij[m]> it supports configuring socketcan interfaces
<jaskij[m]> networkd specifically does
<sveinse> haha, sorry, got a little overexcited here. Yeah, that makes sense. Good to know. We're using CAN
manuel1985 has quit [Quit: Leaving]
<sveinse> I need to see if I can find an overview of the minimal kernel version of the respective systemd releases
<jaskij[m]> it's in the README in the repo iirc
<jaskij[m]> nope
<jaskij[m]> that's for `main`
<jaskij[m]> urgh, my messages got reordered
<sveinse> Yes, thats for *that* release, and then you need to plot a matrix across previous systemd releases
<sveinse> ...which you can use to map against specific yocto releases :P
<jaskij[m]> Dunfell has systemd 244
<jaskij[m]> I tried Hardknott and promptly noped out
<jaskij[m]> too much work, for not enough benefit right now
<jaskij[m]> mostly around i.MX8X support
frieder has quit [Remote host closed the connection]
<sveinse> Testing 5.10.1 on hardnott on imx6 and it seems ok. No graphics on this device fortunately
<jaskij[m]> imx6 is easier, no vendor firmware
<jaskij[m]> we're using SoMs, so there's one more place in the support chain to keep you outdated
<sveinse> aha, that's interesting. So you need properitary things to run on imx8?
<jaskij[m]> imx8 all have that Cortex-M4, right?
<jaskij[m]> it needs firmware which, if you're using a SoM, is provided by your SoM vendor
<sveinse> we're prospecting a new architecture, as imx6 is, what 2012 tech, and imx8 has been proposed
mckoan is now known as mckoan|away
<jaskij[m]> this firmware needs to match version with the security firmware
<jaskij[m]> and iirc both talk with the kernel
<sveinse> there are some interesting stuff in the semi-pro world, like the CM4 from RaspberrPi trading
<jaskij[m]> in my case one of the two is causing an issue when moving to 5.4 mainline and the device simply refuses to boot
<jaskij[m]> I don't even get serial output
<jaskij[m]> sveinse: you kinda lost me there
<jaskij[m]> I know of Pi CM4, but the last two words completely confuse in the context
<sveinse> jaskij[m]: We're exploring if the cm4 from raspberry pi is anything at all, or if it just is a toy
<sveinse> as a replacement to the imx6 board we have
<jaskij[m]> because of the low availability, we've settled on using SoMs using the SMARC standard
<jaskij[m]> kinda bulky, but we don't mind and at least we're not tied to one SoM vendor
<sveinse> right
<sveinse> i got to go, but this has been very interesting. Thanks. See you around.
<jaskij[m]> see you
<sveinse> (we need a good forum/chat for this, but HW-ppl dislike IRC it seems)
<jaskij[m]> sveinse: first of all, CM4 doesn't have built-in CAN, and using an external controller is always a mild PITA
<sveinse> jaskij[m]: yep, I am aware. Major drawback
<jaskij[m]> I'm not sure about Pi4, but the bcm283x in Pi1 to Pi3 is basically a settop SoC
<jaskij[m]> there's i.MX9 around the corner too
<jaskij[m]> they've already announced it, but haven't shown any SoCs yet
<jaskij[m]> yeah, seems like Pi4 doesn't improve much in the peripheral department
<jaskij[m]> yuck
<sveinse> biggest advantage with the cm4 is the huge package/distro community. It's extremely well supported
<jaskij[m]> guessing by you being here, you'll be running Yocto/OE anyway?
<jaskij[m]> so that advantage doesn't exist then, does it?
<sveinse> To be honest don't know. We had one product for 5 years on ubuntu (armhf) and decided that it wasn't worth the stretch to customize it the way we needed it to, enter Yocto. However Yocto is hard for many and it requires tremendous investment in build frameworks
<sveinse> We're run yocto for 6 years or so
roussinm has joined #yocto
<sveinse> The more I use Yocto, the more I enjoy it
<jaskij[m]> yeah, Yocto will draw out every issue in build systems
<jaskij[m]> that too
<jaskij[m]> I've spent what, two weeks? trying to build SciPy
<jaskij[m]> I don't like some of the stuff in meta-scipy, such as a lack of an optimized BLAS
<sveinse> But it does have a curve, and engineers with yocto experience is very hard to get by. I've tried many times on delegating my tasks to others (as I am manager), internal and external looking
<jaskij[m]> really?
<jaskij[m]> I've got no plans to move rn, but last time I looked there was little job offers mentioning Yocto

<jaskij[m]> hmm.... I'm packaging something that's screwing up install paths somewhere... do I just fix it in `do_install_append` or patch CMakeLists.txt?

<vd> kergoth: thank you
<arr> Good afternoon folks. I have a weird issue. A recipe foo-image depends on another recipe/package bar. If I run -c cleansstate for bar and then run bitbake on foo-image, bitbake understands that foo-image depends on bar package and rebuilds it (runs compile, install, package etc tasks including do_package_write_ipk) but it won't run rootfs and image tasks for foo-image. Any ideas why?
<arr> foo-image has "IMAGE_INSTALL = bar" entry in .bb file
<khem> jaskij: usually its better to fix the component build system in your case cmake and also submit upstream to make it cross compile friendly, second option would be to tweak it in do_install
<khem> arr: did anything change in the package bar build after rebuilding ?
<khem> perhaps it found the signatures to be exact and hence did not rebuild image
<arr> khem, yes, there were changes
<khem> ok did these changes result in output of build
<arr> The package bar downloads a binary file as source and simply tars it up as compile step. The binary file changed for sure.
<arr> But the versions and other metadata for the file didn't change.
<khem> well it sounds like its sneaking in things under the nose of bitbake, if tarball changed I wonder why SRC_URI checksums did not change
<arr> The .ipk file produced at the end of write_package_ipk has new file, so output of bar is correct
<khem> I think you could change recipe for bar to explicitly download the tarball via SRC_URI and things will fall into place
davidinux has quit [Ping timeout: 245 seconds]
<arr> khem, Ah. I will try that. Thanks.
<vd> is there a mechanism similar to IMAGE_BOOT_FILES = "some_artifiact;different_name" but for the rootfs?
pgowda has quit [Quit: Connection closed for inactivity]
<khem> vd: what usecase are you looking for ?
whuang0389 has joined #yocto
<vd> khem: I'm embedded several images in my rootfs, for example an initrd, an overlay image, application container images, and the process could be generic: do_rootfs[depends] += "${MY_ROOTFS_DEPENDS}" and a bunch of files copied into ${IMAGE_ROOTFS} from a ROOTFS_POSTPROCESS_COMMAND function. If I could fill a variable with the "from;to" syntax, I
<vd> could make a generic post process function.
<vd> s/embedded/embedding
<khem> hmmm, I guess this are all super image functions perhaps
<vd> khem: so from the recipe or a configuration file I could do for example: MY_ROOTFS_EXTRADEPENDS += "core-image-minimal:do_image_complete" and MY_ROOTFS_EXTRAFILES += "core-image-minimal.squashfs;/var/lib/machines/app.img"

<jaskij[m]> khem: after looking around, seems like at least one path variable is used both for tests and as installation path, and it's altogether a complicated issue
<jaskij[m]> so no upstream patches from me, unfortunately
<jaskij[m]> Plus, it's entirely possible I'm passing wrong paths to the script
<Xagen> when doing a build from toaster, can you force the checkout for a specific layer to be at a specific tag/commit-id instead of a branch?
