| Striking7 | https://git.yoctoproject.org/cgit/cgit.cgi/auto-upgrade-helper/about/ | 15:11 |
| Striking7 | I've followed the directions, but I'm pretty new to yocto, so I haven't been able to get it to properly run. | 15:11 |
| Striking7 | I ran ". ./oe-init-build-env build-auh" from a fresh clone of yocto | 15:13 |
| Striking7 | where does it expect the auto upgrade helper sources to be? | 15:13 |
| Striking7 | I don't see a bitbake target for it either | 15:13 |

| meego | hi there, what might be the Right Way™ of having conditional SRC_URI (a different git branch) depending on the image being built ? | 15:21 |
| kergoth | meego: images are constructed from packages. at the time the package is built, we have no idea what images it'll be installed into | 15:21 |
| kergoth | so you could change it via local.conf between the two builds, to make it rebuild with the new rev, or use two recipes/packages and select between them | 15:22 |
| yates | meego: perhaps having a bbappend in your image layer to modify the SRC_URI? | 15:22 |
| *** learningc <learningc!~learningc@mti-37-145.tm.net.my> has quit IRC | 15:23 | |
| kergoth | unlikely the images are in separate layers, and violates the convention where layer inclusion shouldn't change the build without opting in | 15:24 |

| Striking7 | How can I query what versions of a package are available? | 15:28 |
| meego | thanks for the help. i've considered the .bbappend path. Won't there be a naming issue ? Let's say my debug image has IMAGE_INSTALL_append += "packageX-dbg", and i create a "packageX-dbg.bbapend" file. That bbappend can't modify the packageX build process, can it ? | 15:29 |
| kergoth | package, or recipe? bitbake -s is probably sufficient | 15:29 |
| kergoth | meego: bbappends apply to recipes, not packages | 15:29 |
| Striking7 | Looking at it | 15:29 |
| Striking7 | Thank you. | 15:29 |

| *** User__ <User__!~learningc@219.92.37.145> has quit IRC | 15:30 | |
| Striking7 | kergoth - bitbake -s ran fast enough that it's obviously looking at a local copy | 15:30 |
| kergoth | Striking7: as opposed to what? | 15:30 |
| kergoth | bitbake builds from local recipes, that's what it is | 15:30 |
| Striking7 | is there a utility to run the same type of lookups remotely? For instance, to see if a CVE has been patched yet according to version numbers? | 15:30 |
| jonmason | RP: cool! | 15:31 |
| kergoth | devtool has a subcommand to check for new upstream versions, but you can't build them without using it to first upgrade the recipe | 15:31 |
| Striking7 | Sure - I understand: bitbake is a local deal. Not a problem. That package info has to be grabbed by some utility though | 15:31 |
| Striking7 | Ok, good to know | 15:31 |
| jonmason | where did you put it? in the linux-yocto_4.19.bb? | 15:31 |
| kergoth | no, it doesn't. determining what upstream versions are available used to be entirely manual | 15:31 |
| RP | jonmason: linux-yocto_5.0.bb | 15:31 |
| kergoth | the fact that we have such a tool now is a convenience | 15:31 |
| Striking7 | I agree. I'm trying to figure out how best to use it. | 15:32 |
| zeddii | the kernel part works fine here as well. | 15:32 |
| jonmason | RP: weird, I wonder why it wasn't working for me. Anyway, ship it ;-) | 15:32 |
| Striking7 | Thanks for the tip about devtool | 15:33 |
| meego | kergoth: OK. If i understand correctly, there is no way to conditionally load a bbappend from an image bb file. Because of the layer separation you mentioned. Is that right ? | 15:34 |
| *** stephano <stephano!~stephano@134.134.139.76> has joined #yocto | 15:34 | |
| kergoth | appending an image isn't going to magically change a different recipe | 15:35 |
| kergoth | one recipe can't change how another recipe builds | 15:35 |
| kergoth | yates was proposing changing the recipe configuration based on inclusion of a layer, not changing the image | 15:35 |
| kergoth | afaict anyway | 15:35 |
| kergoth | i'd suggest just changing ther ecipe's SRCREV from local.conf when you switch image builds | 15:35 |
| kergoth | bitbake picks a single provider of a package to build, builds it one way, and then that package is available to install in any and all images | 15:36 |
| kergoth | an image can't change another reicpe/package | 15:36 |
| meego | kergoth: ok understood | 15:36 |
| meego | i'll take the local.conf path. Thank you both for your help. | 15:37 |
| kergoth | you could use a second recipe, and switch versions/providers to select it, or change how the one recipe builds via configuration | 15:37 |
| kergoth | in either case you're having to change providers in the config, so it doesn't matter either way | 15:37 |
| zeddii | @#!@! gmail, RP it filed your follow up from this morning as spam. | 15:39 |

| * kergoth giving serious thought to ditching gmail at some point | 15:39 | |
| yates | please take my suggestion with a grain of salt. kergoth has two orders of magnitude more experience with yocto than i | 15:40 |
| Crofton | only 2? | 15:41 |
| kergoth | it's a valid suggestion, my objections are more to do with conventions and "best practices" .. i hate that term, but drawing a blank | 15:41 |
| yates | Crofton: the order of magnitude estimate is an order of magnitude. could be 20... | 15:42 |
| kergoth | idiomatic. that's the word i was looking for. oe allows you a hell of a lot of flexibility, so a certain amount of thought as to the cleanest most maintainable approach is useful | 15:42 |
| yates | will my .bbappend for a recipe in my layer get utilized when devtool building | 15:42 |
| yates | ? | 15:42 |
| kergoth | devtool build just runs bitbake | 15:43 |
| kergoth | if the layer is included, and the bbappend matches the patterns in BBFILES, and its filename matches the recipe, it'll be applied whether you're using devtool or not | 15:43 |
| yates | kergoth: aha. that was going to be antoher question: difference between "devtool build <recipe" and "bitbake <recipe"? nada? | 15:43 |
| yates | within context of a devtool modify, that is | 15:44 |
| Striking7 | Is there a way to roll a package back to a previous version using bitbake, devtool, and the like? | 15:45 |
| kergoth | looks like it just bitbakes the populate_sysroot packagedata tasks for you, optionally temporarily disabling parallel make during the build | 15:45 |
| kergoth | https://github.com/openembedded/openembedded-core/blob/master/scripts/lib/devtool/build.py | 15:45 |
| yates | Striking7: seems like a git/svn function, | 15:45 |
| kergoth | https://github.com/openembedded/openembedded-core/blob/master/scripts/lib/devtool/build.py#L57-L73 | 15:45 |
| kergoth | https://github.com/openembedded/openembedded-core/blob/master/scripts/lib/devtool/build.py#L49-L51 | 15:45 |
| Striking7 | Reading your links - thanks for the info | 15:45 |
| kergoth | those 3 links were for yates | 15:46 |
| kergoth | to "roll back" a version you need to change/rename the recipe to the old version, and adjust patches appropriately | 15:46 |
| Striking7 | Oh, came in kind of handy for me anyway :-) | 15:46 |
| kergoth | if we already had a recipe for the old version at some point, as yates says, use git to resurrect the old version | 15:46 |
| Striking7 | ok. | 15:46 |
| kergoth | bitbake only builds the verisons of the recipes we have in the layers, not arbitrary versions | 15:47 |
| kergoth | devtool assists with upgrades to newer upstream versions, but you'll have to fix patches, if we'd already built the old version, it makes more sense to pull it out of source control than to re-do the work | 15:47 |
| Striking7 | Makes sense. | 15:47 |
| yates | back to the .bbappend question, i have a .bbappend in a layer which should be selected for matchbox-wm which is simply this: https://paste.fedoraproject.org/paste/jrnTHd6sigstMaPuPqlQsg | 15:48 |
| Striking7 | I don't mind doing it that way, I'm just trying to figure out all the data that's available to me here. For instance, one thing we would really like is a list of available package versions | 15:48 |
| yates | yet the ./configure option --enable-composite" is not being specified | 15:48 |
| Striking7 | I can get the list of latest packages, but not info about previous versions for a single package. | 15:48 |
| kergoth | †he only list you can get is what recipes you have right now, or what upstream upgrades are available. by policy we don't keep old versions around in our layers, it's a maintenance nightmare to keep everything building going forward | 15:49 |
| Striking7 | Of course, I understand completely | 15:49 |
| kergoth | *if* the recipe name includes the version, i.e. for non-git recipes, you could use git to extract a list of the files we've removed from history | 15:49 |
| kergoth | Striking7: https://github.com/kergoth/dotfiles/blob/master/git/scripts/git-attic | 15:50 |
| Striking7 | So really all the remote access these tools do is git? | 15:50 |

| kergoth | via http://chneukirchen.org/dotfiles/bin/git-attic | 15:51 |
| yates | there | 15:51 |
| kergoth | Striking7: no, devtool's upgrade checking uses patterns and remote urls to check for remote version availability | 15:51 |
| Striking7 | Thanks kergoth | 15:51 |
| kergoth | but other than that,e verything is local | 15:51 |
| yates | i need "Building with Composite manager" to be "yes" | 15:51 |
| kergoth | yates: make sure your append is in an included layer (see conf/bblayers.conf in BBLAYERS) and in the correct path to be included (see BBFILES in <layerdir>/conf/layer.conf) | 15:51 |
| Striking7 | kergoth: perfect! I'll dive into its source to see where all that comes from. That looks like the right direction for me | 15:52 |
| kergoth | and the filename has to match the recipe | 15:52 |
| yates | i'm using matchbox-wm_%.bbappend - wouldn't that work ? | 15:52 |
| kergoth | bitbake/oe is designed to be self-contained and independent of host and target distro and machine, we've never designed or implemented a protocol to access metadata anywhere but in the local layers | 15:52 |
| kergoth | yates: also, use bitbake-layers show-appends, way quicker way to check if it's being applied | 15:53 |
| *** meego <meego!500b97ce@gateway/web/freenode/ip.80.11.151.206> has quit IRC | 15:53 | |

| yates | ok | 15:53 |
| kergoth | that filename is fine, yeah, so check layer inclusion and its location within the layer | 15:53 |
| kergoth | you can't just drop a bbappend wherever you want, it has to match the wildcards in BBFILES in the layer it's in | 15:53 |
| kergoth | i.e. <layerdir>/recipes-*/*/*.bbappend, or whatever | 15:54 |

| kergoth | np. that attic script is handy, particularly since it includes the last commit where the file existed, so you can look at the recipe with git show, or use checkout to resurrect it | 16:00 |
| Striking7 | veeeeery cool | 16:00 |
| Striking7 | This is all still a bit over my head - I just started this job Tuesday. | 16:01 |
| Striking7 | So the terminology (recipe vs. package, layers, etc) is all still soft and squishy in the brain | 16:01 |
| kergoth | no worries, we all have to start somewhere, and oe/yocto is complex (of necessity, due to the flexibility), with a fairly steep learning curve | 16:01 |
| kergoth | once you grasp the big picture it starts to come together in your head, i think | 16:01 |
| kergoth | but some learn best bottup-up, others top-down, so depends on the person | 16:02 |
| Striking7 | Totally understand - I usually do a little of each | 16:06 |
| Striking7 | lets you use your right brained creativity in "reverse engineering" from top down, lets you use left brain methodical tendencies for bottom up | 16:06 |

| yates | would be nice if bitbake-layers show-appends took a recipe as a final argument, so you don't have to grep through ALL appends to fihd the one... | 16:59 |
| kergoth | not a bad idea, maybe submit a bug to bugzilla? | 16:59 |
| kergoth | debatable whether it should accept layer or recipe as first argument, so probably use an option. -r RECIPE or something | 17:00 |
| yates | kergoth: good idea. just to complete, was i right on the application of the BBFILES in layer.conf? | 17:01 |
| kergoth | yes, bblayers lists layers to process, conf/layer.conf is parsed in each layer to construct a final BBPATH and BBFILES, and bitbake uses those to do the actual parsing | 17:01 |
| yates | ack - good. | 17:02 |
| kergoth | then BBFILE_COLLECTIONS/BBFILE_PATTERN_<name>/BBFILE_PRIORITY_<name> controls layer priority. when the same recipe exists in multiple layers with different versions, the higher priority layer recipe is used, even if it's the older one, unless PREFERRED_VERSION selects explicitly | 17:02 |

| Striking7 | So I like devtool so far - its "upgrade" command takes a preferred version as a param, and it can downgrade or upgrade pretty seamlessly. | 20:00 |
| Striking7 | What I'd like is to get a list of versions of a package that are available and present that to the user | 20:00 |
| Striking7 | (or rather, long term, to another component in the system) | 20:00 |
| *** armpit <armpit!~armpit@45.19.219.178> has joined #yocto | 20:00 | |
| Striking7 | Anyone know if devtool has a way of doing that already? I know it's using SRC_URI and scraping latest_version from there, but I wasn't sure if it stored all the versions available as well | 20:01 |
| khem | JPEW: icecc in my env did not solve the world hunger | 20:01 |
| khem | JPEW: I have 16Core+16GB+300GB-SSD | 20:01 |
| Striking7 | khem - that's the worst: I hate it when my code fails to solve world hunger | 20:01 |
| JPEW | khem: Too bad. It is a bit twiddly.... for example, we are all running a patched version of icecc | 20:02 |
| khem | and I add another box with same spec and build times are same or worse | 20:02 |
| khem | I guess n/w is my bottleneck | 20:02 |
| khem | I need 10G backhaul | 20:02 |
| JPEW | That would be nice. What do you have now? | 20:03 |
| khem | or maybe even thats not enough to beat SSDs | 20:03 |
| khem | JPEW: this is some cloud that someone else manages I have asked them the question | 20:03 |
| JPEW | khem: Could be the SSDs. I still have spinny drives | 20:04 |
| khem | JPEW:I am doing another experiment where I will have 4 8 core machines as slaves and then do -j30 to build chromium-x11 | 20:04 |
| khem | yeah SSDs are the biggest improvement for OE builds I agree | 20:05 |
| yates | JPEW: it looks like that is for wayland | 20:05 |
| yates | we are using x11 | 20:05 |
| JPEW | Ah. too bad | 20:05 |
| khem | yates:you can look into westeros which is a light weight wayland compositor | 20:05 |
| khem | https://github.com/rdkcmf/westeros | 20:06 |
| yates | JPEW: have you used wayland/weston on an embedded device with like a smallish LCD display? (ours is 800x480) | 20:06 |
| khem | yates:whats the app ? | 20:06 |
| khem | do you run in kiosk mode ? | 20:06 |
| yates | khem: i don't understrand the question(s) | 20:07 |
| khem | x11+qt5 is decent | 20:07 |
| yates | we are using x11+wxwidgets | 20:07 |
| JPEW | yates: I've used weston for testing purposes. We have our own proprietary wayland compositor we use in production (not by choice.... I'd rather use weston) | 20:07 |
| JPEW | weston is pretty configurable with plugin shells and such | 20:08 |
| yates | JPEW: would it be easy to bring weston/wayland in instead of x11/matchbox? | 20:08 |
| khem | weston is heavier, surely thats why we wrote westeros for RDK and its opensource( Apache-2.0) so enjoy and contribure back | 20:08 |
| JPEW | yates: depends on what applications you want to run on top of it | 20:08 |
| JPEW | yates: Just getting weston is pretty easy | 20:09 |
| JPEW | IMAGE_INSTALL += "weston" | 20:09 |
| khem | or base your image on top of core-image-weston | 20:09 |
| JPEW | Oh, ya that would work :) I didn't even know that was a thing | 20:09 |
| JPEW | khem: Does core-image-weston default weston to use DRM for hardware accelerated rendering? | 20:10 |
| yates | DRM? | 20:10 |
| khem | We have a browser based UI running on top of wayland+westeros doing full HD video in less than 512M RAM device | 20:10 |
| JPEW | yates: Direct Rendering Management, basically the kernels GPU API | 20:11 |
| khem | see https://github.com/WebPlatformForEmbedded/meta-wpe | 20:11 |
| JPEW | yates: AFAIK, weston in OE defaults to using (non-accelerated) framebuffer backend, which might feel pretty slow. If you have a GPU, enabling the DRM backend in weston makes it much better :) | 20:12 |
| yates | holy crap! | 20:12 |
| yates | no, nothing near HD video required in our stuff. | 20:13 |
| yates | but we do want sexy-looking UI with gradients, transparency, etc. | 20:13 |
| JPEW | yates: sure, are you using OpenGL (or OpenGLES) for that? | 20:14 |
| yates | i don't know... (sheepish look). i'm using wxWidgets wxDC classes and a little of my own, but transparencies don't work because we have no compositor | 20:16 |
| yates | wxDC has a built-in gradient fill | 20:16 |
| yates | perhaps under-the-hood wx uses OpenGL | 20:17 |
| yates | ? | 20:17 |
| JPEW | yates: Probably not | 20:17 |
| khem | wxwidgets would use opengl if platform enabled it | 20:19 |

| khem | build it with --with-opengl | 20:20 |
| yates | thanks for all the input folks, i'm still parsing/thinking on it. | 20:20 |
| yates | khem: you mean build wxWidgets --with-opengl? | 20:20 |
| khem | yes | 20:20 |
| khem | and ensure that your graphics driver supports openGL and is enabled there too | 20:21 |
| JPEW | FWIW: My recollection is that wxDC is a simple (non-acclerated) raster bitmap backing, and there are other classes for using OpenGL in wxWidgets, but I could be wrong | 20:21 |
| yates | yes, we already are: https://paste.fedoraproject.org/paste/UC7v7DGyhgPfuYhQYMht8w | 20:21 |
| yates | this is from the wx recipe i wrote a few weeks back. | 20:22 |
| khem | thats possible maybe they rely on GLX | 20:22 |
| yates | libglu is a depends - is that opengl? | 20:22 |
| *** nerdboy <nerdboy!~sarnold@gentoo/developer/nerdboy> has joined #yocto | 20:22 | |

| yates | so it's not wx | 20:25 |

| *** dv_ <dv_!~dv@62-178-50-190.cable.dynamic.surfer.at> has joined #yocto | 20:37 | |
| yates | i'm just trying to determine the quickest way to get our project transparency. | 20:37 |
| yates | if that means switching to weston/wayland, so be it. | 20:38 |
| yates | that will also probably be the time to upgrade morty to something this century.. | 20:38 |
| yates | it seems wayland is the wy of the future. | 20:38 |
| yates | but i do have questions. like can i still run an xterm if x11 is not there? | 20:39 |
| yates | can i run vnc server ? | 20:40 |
| yates | yada yada.. | 20:40 |
| yates | i guess i'm ignorant of the deeps parts of x11 versus wayland | 20:40 |
| yates | deep | 20:40 |
| yates | khem: are you implying that if the graphics driver supported openGL and it is enabled there, that we'd have transparencies with matchbox-wm? | 20:45 |
| yates | matchbox-wm + wxWidgets, that is? | 20:48 |
| rburton | yates: those comments are not very accurate. we autoreconf mbwm for a start | 20:52 |
| rburton | yates: nobody that i'm aware of has used the compositor since nokia/maemo so who knows if it still *works* | 20:52 |
| rburton | yates: ideally, just ditch X entirely and use weston | 20:52 |
| yates | right, coming to the same conclusion | 20:53 |
| rburton | x11 is legacy at this point basically | 20:54 |
| rburton | if you can use wayland | 20:54 |
| yates | khem/rburton: by "base your image on core-image-weston" do you mean "inherit core-image-weston" instead of "inherit core-image"? | 20:55 |
| rburton | no, i mean ditch X entirely and use weston | 20:55 |
| rburton | core-image-weston is an example, like core-image-sato | 20:55 |
| rburton | enabling compositing in mbwm is most likely trivial though | 20:55 |
| yates | rburton: oh? | 20:56 |
| rburton | --enable-composite and come back with patches | 20:56 |
| yates | you mean just rewrite part of the compositor? | 20:57 |
| yates | :) | 20:57 |

| *** armpit <armpit!~armpit@45.19.219.178> has quit IRC | 21:29 | |
| psrcode | but if I take the lttng-tools recipe which define PACKAGECONFIG ??= "lttng-ust" lttng-ust is not present in the end image. | 21:30 |
| *** wildwillie <wildwillie!50d98c5d@gateway/web/freenode/ip.80.217.140.93> has joined #yocto | 21:31 | |
| psrcode | I have to add PACKAGECONFIG += "lttng-ust" to a bbapend (lttng-tools) to see lttng-ust feature used | 21:31 |
| psrcode | is it because lttng-ust is not part of the "runtime dependencies" and only in the "build dependencies"? | 21:33 |
| wildwillie | Hi, Anyone here using RPI3 with Yocto? I have tried following : https://jumpnowtek.com/rpi/Raspberry-Pi-Systems-with-Yocto.html but I cannot get it generate the bootcode.bin. This whole workflow is very different from other stuff, like imx6 | 21:34 |
| RP | psrcode: PACKAGECONFIG is primarily about build time things | 21:36 |
| RP | psrcode: What would work here is to change the lttng-ust line to PACKAGECONFIG[lttng-ust] = "--with-lttng-ust, --without-lttng-ust, lttng-ust, lttng-ust" | 21:38 |
| RP | psrcode: that 4th position in the PACKAGECONFIG entry adds to RDEPENDS | 21:38 |
| RP | psrcode: so then the lttng-tools package would depend on lttng-ust | 21:39 |
| RP | psrcode: normally we pick up rdepends through dynamic linking analysis but I guess lttng doesn't directly link to ust | 21:40 |
| psrcode | RP: based on the PACKAGECONFIG ??= line was it the intention to have lttng-ust by default? | 21:40 |
| RP | psrcode: I think so | 21:40 |
| psrcode | because lttng-tools can be built without lttng-ust | 21:40 |
| psrcode | if so this solve a big chunk of the ptest suite | 21:41 |
| RP | psrcode: ah, interesting. Yes, its being made configurable and turned on there | 21:41 |
| psrcode | still we do have a fuckup on our side regarding how we handle ust dependant tests | 21:41 |
| RP | psrcode: I guess we just never realised there wasn't a direct linkage to cause it to be pulled in | 21:42 |
| psrcode | I'm looking into adding the python agent option on lttng-ust so we can run the python agent test via lttng-tools, otherwise the ptest suite works all green | 21:42 |
| RP | psrcode: sounds great! :) | 21:43 |
| psrcode | RP: there was a couple missing dep for the tests and 1~2 fuckup on our side. I'll send you a RFC when I'm confident with the work. | 21:43 |
| psrcode | next step will be to have all this integrated in our CI to track stuff either from scratch or using report from your builder | 21:44 |
| RP | psrcode: FWIW our ptest builds do run lttng-tools-ptest at least on qemux86 | 22:02 |

| rburton | yes | 23:42 |
| bluelightning | unless you specified that path (unlikely), devtool modify checks out the source to workspace/sources/<recipename> | 23:42 |
