| 18:51.58 | felix_inst | I am struggling a bit with why a config fragment I made does not seem to get applied. I see the fragment pop up in build/tmp/work/plat-linux/.. along with other applied fragments. For whatever reason, though, the one I added is not reflected in .config - why would that be? |
| 19:10.38 | zeddii | what's your kernel provider / kernel recipe. step 1) does it inherit kernel-yocto ? or include linux-yocto.inc ? |
| 19:14.26 | felix_inst | this is with a linux-xlnx kernel - checking on the includes |
| 19:21.49 | felix_inst | it includes linux-yocto.inc |
| 19:22.32 | zeddii | so that's good. fragments are never ignored or not applied, but that doesn't mean their settings always make it into the .config |
| 19:23.02 | zeddii | if there's a missing dependency, or another option in the kernel selects/clears a CONFIG, what's in your fragment won't be in the final .config |
| 19:23.24 | zeddii | I have audit tools for the latest releases that can help explain that, but not for the releases that Xilinx supports. |
| 19:23.41 | felix_inst | yes, I am having trouble seeing layer priorities because I need to work through petalinux |
| 19:24.26 | felix_inst | for the option I want, I also tried enabling all required settings in the same fragment to make sure |
| 19:25.10 | felix_inst | is the fact that I see the cfg file in the build tree enough of an indication that I didn't mess up the recipe? |
| 19:25.28 | zeddii | you would get a fetcher error if the .cfg wasn't picked up. |
| 19:25.36 | felix_inst | because that part seemed simple - and I can at least start looking elsewhere if I can cross that one off the list |
| 19:26.10 | zeddii | try doing a menuconfig on the kernel via bitbake, and search up the option you are trying to set. |
| 19:26.18 | zeddii | the dependencies and selcted implications will be listed there. |
| 19:26.41 | felix_inst | that's what I did - should be fine |
| 19:27.05 | felix_inst | I do get an info saying that ../linux-xlnx/oe-local-files/devtool-fragment.cfg would be removed |
| 19:27.11 | felix_inst | any idea what that is all about? |
| 19:28.12 | felix_inst | and that file doesn't exist - sorry if this is a xilinx specific question |
| 19:28.46 | felix_inst | oh nvm, that's from config not build |
| 19:29.55 | felix_inst | build seems to have no related messages other that it is compiling from an external source tree |
| 19:32.12 | felix_inst | and in that tree's config I have the prerequisites set, but not the option I am trying to enable |
| 19:33.15 | zeddii | hmm. is it using externalsrc ? |
| 19:33.35 | zeddii | if so, the config steps were inhibited for that in the past. |
| 19:33.39 | felix_inst | how do I check on that? sorry, utterly new to all of this |
| 19:36.08 | zeddii | what's the exact message about the external src tree you are seeing ? |
| 19:37.19 | felix_inst | NOTE: linux-xlnx: compiling from external source tree /home/user/components/yocto/workspace/sources/linux-xlnx |
| 19:38.22 | felix_inst | i see a "inherit externalsrc" in a kernel .bbappend - so that means it *is* using externalsrc I assume |
| 19:39.27 | zeddii | yup. |
| 19:39.51 | zeddii | let me see if I can raise someone else to comment ... fray you around ? |
| 19:40.21 | felix_inst | awesome, i appreciate the help! |
| 19:40.35 | zeddii | what's the xilinx release ? if I map it to the base yocto release, we can peek to see if that was before or after the configuration step was inhibited. |
| 19:40.59 | felix_inst | is there some section in the documentation i should read? i went through config fragements getting me to this point ;) |
| 19:41.17 | felix_inst | xilinx 2020.1 |
| 19:42.25 | felix_inst | oh i see - shouldn't I be able to get my option turned on with a defconfig I make? |
| 19:42.52 | felix_inst | i was just trying to do it in a custom layer to leave the base config untouched if at all possible |
| 19:43.20 | zeddii | possibly, but it goes through the same process as a fragment, and defconfig will overlay any base stuff completely. |
| 19:43.55 | felix_inst | hmm, I do have fragments in other layers as well, though - wouldn't those have the same issue? |
| 19:44.16 | zeddii | possibly. |
| 19:44.33 | felix_inst | let me check if all of those option apply properly |
| 19:44.56 | zeddii | i don't know how the petalinux build is structured, if you can find the work-shared/$MACHINE/kernel-source directory, there are logs, etc, to check. |
| 19:48.16 | felix_inst | i see debug messages searching for the .cfg file - but nothing that looks like a warning or error |
| 19:49.56 | zeddii | which file exactly did you check ? |
| 19:50.17 | felix_inst | i grepped all of them in the oe-logs folder |
| 19:51.34 | zeddii | not sure if anything specific would be in there, this is internal to config merge process, it isn't dumped to what bitbake/oe would pick up. |
| 19:51.51 | zeddii | there's a ".kernel-meta" subdirectory under the kernel-source directory that would have more info. |
| 19:52.08 | felix_inst | i am also looking at merge_config_build.log now - but don't see my setting in there |
| 19:52.30 | felix_inst | yeah that's the file you are talking about I think |
| 19:53.21 | zeddii | then, the kernel recipes may be clobbering the SRC_URI or something else. bitbake would have errored if it wasnt found at that level. |
| 19:53.30 | felix_inst | are bsp.cfg and user.cfg somehow special? |
| 19:53.32 | zeddii | and the merge never "ignores" a file. |
| 19:53.34 | zeddii | nope. |
| 19:53.52 | zeddii | something is injecting them from the petalinux side of things |
| 19:53.59 | zeddii | but they aren't special outside of that. |
| 19:54.10 | felix_inst | but are they somehow not subject to the inhibit you mentioned earlier? |
| 19:54.19 | felix_inst | or declared exempt or something? |
| 19:54.37 | felix_inst | I am wondering if I can append those .cfg files - that's why I am asking |
| 19:54.44 | felix_inst | instead of making a new fragment |
| 19:54.55 | zeddii | if you can find them, then probably. |
| 19:55.06 | zeddii | and no, either the configuration tasks run, or they don't |
| 19:55.22 | zeddii | and it does sound like they are running, so they've made sure the task is running with their externalsrc setup. |
| 19:55.27 | felix_inst | they do in some cases, not in others ;) |
| 19:57.00 | felix_inst | that file shows a whole bunch of conflicts, though. but those problems are all in the xilinx/avnet setup. that's scary |
| 19:58.24 | zeddii | conflics/overrides are fun, just the way things work. to both be standalone and/or additive. |
| 19:59.16 | felix_inst | this one is avnet overriding xlnx - but I am using the exact versions for which the contraption was developed |
| 19:59.40 | felix_inst | so I am a bit surprised these things didn't get ironed out in development - or am i missing something here? |
| 20:00.15 | zeddii | I don't understand the setup and petalinux, so I can't say. |
| 20:00.16 | felix_inst | screw it, I will do the config manually and add a note for now... |
| 20:00.51 | felix_inst | I am also a bit overwhelmed figuring that out |
| 20:01.25 | zeddii | if you are in that .kernel-meta directory in the kernel source dir. |
| 20:01.32 | zeddii | there's also a file 'config.queue' |
| 20:01.41 | zeddii | see if your fragment is listed in there. |
| 20:01.54 | felix_inst | i see config.baseline and config.new |
| 20:02.00 | marex | reads about scc and cringes ... |
| 20:02.21 | zeddii | has no shits to give |
| 20:02.27 | zeddii | felix_inst: those are different files. |
| 20:02.28 | marex | felix_inst: you dont happen to have two fragments named exactly the same , or named differently but in the same kmeta directory , included in the build ? |
| 20:02.43 | marex | zeddii: I am not gonna complain about meta-xilinx this time :-) |
| 20:02.45 | marex | I promise |
| 20:02.55 | felix_inst | marex, they have different names |
| 20:03.16 | zeddii | config.baseline and config.new are not files from the standard OE/yocto components |
| 20:03.17 | marex | OK, it was one thing which I ran into and which was caused me a great deal of pain |
| 20:03.30 | zeddii | they must be petalinux junkers |
| 20:03.48 | zeddii | what's the path of the directory that you are finding them ? |
| 20:04.06 | zeddii | doesn't mind some meta-xilinx or petalinux shade. it's all good fun. |
| 20:05.05 | felix_inst | build/tmp/work-shared/uz3eg-iocc/kernel-source |
| 20:05.25 | zeddii | and then .kernel-meta ? |
| 20:05.38 | felix_inst | yes |
| 20:06.41 | felix_inst | hang on, found a config.queue |
| 20:06.49 | zeddii | and there's a config.queue file there ? are they listed in that ? I think they may be commiting some other crime. Another thing you can do is a: bitbake -e linux-xlnx and see what the SRC_URI contains. |
| 20:06.56 | felix_inst | configs//./axisfifo.cfg # non-hardware |
| 20:07.01 | felix_inst | mine is listed in there |
| 20:07.19 | zeddii | ok. so it will be applied, but other things can still impact the final.confg |
| 20:07.40 | zeddii | what comes after it in the file ? those can still turn things off, etc, after that fragment. |
| 20:08.11 | felix_inst | https://pastebin.com/80pCS4KV |
| 20:08.30 | felix_inst | oh i see, so those are the configs I gotta work through and make sure my setting stays active? |
| 20:08.48 | zeddii | the queue is merged in that order, last one through the gate "wins" |
| 20:08.49 | felix_inst | and bottom is highest prio? |
| 20:08.57 | felix_inst | k |
| 20:09.07 | zeddii | so if you are unlucky something is impacting the option you are trying to change. |
| 20:09.58 | zeddii | there are some ways to bounce up the priority of yours via the KERNEL_FEATURES variable, but I'd have to know the version to get the incantation right. |
| 20:10.30 | zeddii | but somewhere in the kernel recipe chain, the SRC_URI being appended to bring those in. |
| 20:10.33 | felix_inst | oh so that is to bump up prio of part of a layer but not all of the layer? |
| 20:10.48 | marex | zeddii: is there some more detailed documentation for the inner workings of SCC ? |
| 20:10.54 | zeddii | these don't really follow that, it's just SRC_URI ordered. |
| 20:10.59 | marex | it seems it is not just me struggling with the tool |
| 20:11.30 | zeddii | we had it documented about 8 years ago, but they chucked all those in the bin for simpler docs. |
| 20:11.39 | zeddii | but scc isn't in play here. |
| 20:12.03 | zeddii | for the most part anyway. |
| 20:13.21 | felix_inst | i grepped for CONFIG_XIL_AXIS_FIFO in all .cfg files and no other ones contain that |
| 20:13.28 | felix_inst | so I don't think anything else overwrites |
| 20:13.43 | felix_inst | am i not looking for the final config in the right spot? |
| 20:14.00 | zeddii | that's the kernel build dir, which i'm not sure what they set it to. |
| 20:14.19 | felix_inst | build/tmp/work/uz3eg_iocc-xilinx-linux/linux-xlnx/5.4+git999-r0/linux-xlnx-5.4+git999/.config:4551:# CONFIG_XIL_AXIS_FIFO is not set |
| 20:14.35 | felix_inst | build/tmp/work-shared/uz3eg-iocc/kernel-build-artifacts/.config:4550:# CONFIG_XIL_AXIS_FIFO is not set |
| 20:14.53 | felix_inst | these are the two .config files with the setting I care about - and it's disabled in either one |
| 20:14.57 | zeddii | yep. that's the one. so something is still missing to turn it on or something else is unselecting it. |
| 20:15.07 | zeddii | what's the Kconfig block look like for it ? |
| 20:15.13 | zeddii | i.e. the source code. |
| 20:16.07 | felix_inst | https://pastebin.com/HwT01sW7 |
| 20:16.25 | felix_inst | not much there - and OF is enabled in the final config it seems |
| 20:17.02 | zeddii | yah. I can't imagine it is off. |
| 20:17.48 | zeddii | and that's in the externasrc tree ? or is it an out of tree module ? |
| 20:19.13 | felix_inst | the source is in the external tree |
| 20:19.48 | zeddii | that matters in the sense that even if dependencies are on, the Kconfig may not be reachable. i.e. some other surrounding menu option is disabled. |
| 20:19.55 | felix_inst | and the config.new in that tree is a synlink to one of the two config files that i just mentioned |
| 20:20.06 | felix_inst | the first one |
| 20:20.17 | felix_inst | so that's how they connect I suppose |
