Dec 17 08:12:05 <stuom1> what should I remove from tmp/ that bitbake would rebuild them and not complain that something is missing?
Dec 17 08:12:34 <stuom1> I can remove whole build/ but i dont want that since rebuild would take half a day
Dec 17 08:15:08 <Mr0rris0> got this pdf, whats it mean really

Dec 17 08:15:36 <Mr0rris0> in Computer-Communication Networks
Dec 17 08:15:56 <LetoThe2nd> Mr0rris0: hum, how come you think we do explain CS theory?
Dec 17 08:16:34 <Mr0rris0> cant say, just not sure if any if it applies to what i glanced over this bein about
Dec 17 08:17:21 <Mr0rris0> if not then thats something, i mean i dunno, i guess it informs me of something
Dec 17 08:17:34 <LetoThe2nd> Mr0rris0: without atually looking at it, spanning trees in networks are usually about routing.
Dec 17 08:19:26 <erbo> stuom1: you can remove all of build/tmp/*, it should "rebuild" quite fast since it will use the sstate-cache
Dec 17 08:23:47 <stuom1> @erbo Ok I'm trying that thanks. It gives me massive error spam for about every recipe that "The recipe XXX is trying to install files into a shared area when those files already exist". Is that expected?
Dec 17 08:29:26 <stuom1> "ERROR: XXX do_package_write_ipk: If the above message is too much, the simpler version is you're advised to wipe out tmp and rebuild (reusing sstate is fine). That will likely fix things in most (but not all) cases.
Dec 17 08:29:47 <stuom1> wiping out tmp is what I just did, causing the errors
Dec 17 08:42:51 <LetoThe2nd> stuom1: wiping out, in the meaning of completely removing tmp?
Dec 17 08:45:22 <stuom1> LetoThe2nd yes
Dec 17 08:45:41 <LetoThe2nd> stuom1: strange, that is totally unproblematic
Dec 17 08:48:45 <stuom1> ls
Dec 17 08:56:11 <nacknick> Hi. I want to add package manager ("apt-get") to my rpi3-yocto image. After adding EXTRA_IMAGE_FEATURES += "package-management" and modify PACKAGE_CLASSES ?= "package_deb" in local.conf file, I guess that I need to add repositories to the image so I will able to use "apt" command. How to do it? I want to add recipes that available from
Dec 17 08:56:12 <nacknick> openembedded.org afterwards
Dec 17 08:57:29 <LetoThe2nd> nacknick: sorry, thats not how it works
Dec 17 08:57:44 <LetoThe2nd> nacknick: openembedded does *not* provide package feeds.
Dec 17 08:58:23 <RP> kanavin: I think with the feedback I've just sent that means you have feedback on most of the unmerged patches. I'm going to wait for a new queue now for those.
Dec 17 08:59:30 <nacknick> letothe2nd: OK. So what should I do to be able to install packages after the image is running?
Dec 17 09:00:31 <LetoThe2nd> nacknick: you'd have to set up your ownb package repository -> https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/package-manager-white-paper.pdf
Dec 17 09:01:20 <LetoThe2nd> nacknick: but usually its way better to think about your usecase first. if you want an interactive system to tinker on and install packages at random, then OE/yocto is just not what fits your needs.
Dec 17 09:01:55 <LetoThe2nd> nacknick: the OE way is to think and decide what one needs *before* building, and then create a custom image that exactly suits the usecae.
Dec 17 09:04:42 <nacknick> LetoThe2nd: Thank you
Dec 17 09:04:56 <LetoThe2nd> nacknick: have fun.
Dec 17 09:05:27 <LetoThe2nd> nacknick: i think episode #2 gives a pretty good outline of how to do custom images: https://www.youtube.com/playlist?list=PLD4M5FoHz-TxMfBFrDKfIS_GLY25Qsfyj
Dec 17 09:14:59 <stuom1> LetoThe2nd I had to remove build/deploy along with build/tmp to get rid of errors
Dec 17 09:15:59 <LetoThe2nd> stuom1: ok. so you deliberately pulled deploy *out* of tmp?
Dec 17 09:17:16 <stuom1> I didn't, but maybe somebody did :D
Dec 17 09:17:22 <LetoThe2nd> thats very uncommon, and probably part of your problem. whenever somebody here says "wipe tmp", it is implicitly assumed that everything that is neither sstate nor downloads is removed.
Dec 17 09:21:52 <stuom1> I think my local.conf is pretty much default what came with Toradex's sources, and yes deploy dir is separate
Dec 17 09:22:09 <LetoThe2nd> go blame toradex
Dec 17 09:22:16 <stuom1> I will ;)
Dec 17 09:22:52 <LetoThe2nd> why would anybody ship you a local.conf for any reason other than hiding dirty hacks, no idea.
Dec 17 09:29:03 <kroon> When I run out of disk space, its not possible to start new tasks, not even 'clean'-task for a recipe in order to free up space. Are there any other way to salvage the build except wiping TMPDIR ?
Dec 17 09:37:38 <qschulz> kroon: to be able to run bitbake, maybe modify BB_DISKMON_DIRS? https://www.yoctoproject.org/docs/current/ref-manual/ref-manual.html#var-BB_DISKMON_DIRS
Dec 17 09:38:22 <qschulz> kroon: but I always just remove TMPDIR since with the sstate-cache it's pretty fast
Dec 17 09:39:08 <kroon> qschulz, ah.. I guess you mean temporarily lower the limits in order to run emergency cleanup tasks. sounds reasonable
Dec 17 09:39:44 <JaMa> anyone seeing higher inode usage recently?
Dec 17 09:40:49 <JaMa> I'm on 4M limit in TMPDIR with relatively small image
Dec 17 09:52:10 <stuom1> has anybody tried to make a recipe for scipy using pip?
Dec 17 09:52:57 <LetoThe2nd> stuom1: it has been asked several times, but i don't think there something out there.
Dec 17 09:54:29 <stuom1> yeah all I find is different problems with it but no solutions
Dec 17 10:09:24 <lfa> hello! I have a board which can have two different flash sizes (4 and 8GB). I'm using wic to create a "data" ext4 partition. This data partition should have a differnt size for the 4 GB and 8GB flash
Dec 17 10:09:57 <LetoThe2nd> lfa: 2 machine files which include  all the common parts and just route to separate wks files
Dec 17 10:10:01 <lfa> What's the best practice to handle a situation like this? Generate two different wic images? Resize the partition dynamically on first startup?
Dec 17 10:10:14 <LetoThe2nd> lfa: the wks files an also have a common include
Dec 17 10:10:29 <LetoThe2nd> and therefor just haev different sizes.
Dec 17 10:10:38 <LetoThe2nd> (thats the blunt, common aproach)
Dec 17 10:11:11 <lfa> Ok, so I should create two machines?
Dec 17 10:11:23 <LetoThe2nd> the rest depends on your use case.
Dec 17 10:11:59 <LetoThe2nd> it can be possible to resize on first startup. or maybe the only difference is in some for of data partition. or, or, or
Dec 17 10:12:25 <LetoThe2nd> the 2machine approach certainly works, but there might be more elegant ones for your specific usecase.
Dec 17 10:14:36 <qschulz> lfa: are you sure only the size changes? no page size? no block size? etc. If there's any chance that size is not the only change, different machines. If there is even the smallest chance the flash chip will change, different machines. (considering flash = nand device)
Dec 17 10:14:45 <qschulz> considering/assuming
Dec 17 10:14:51 <lfa> ok, thanks. I will look into it. Two machines sounds a bit cumbersome, as really the only difference is the size of this partition (which is empty in the image btw)
Dec 17 10:14:55 <lfa> qschulz: it's an eMMC
Dec 17 10:15:36 <lfa> sorry, should have mentioned that :)
Dec 17 10:16:05 <qschulz> lfa: or create two wic images with different sizes. Don't know if it's supported already though
Dec 17 10:16:16 <qschulz> but usually, different hardware = different machines
Dec 17 10:18:10 <LetoThe2nd> its the better safe than sorry appraoch.
Dec 17 10:20:45 <lfa> well.. there are other hardware differences too, but all these are handled during "runtime". I followed the approach the imx6 sabresd boards took. 1 machine, supporting different variants (e.g. iMX6 Solo vs Quad)
Dec 17 10:21:26 <lfa> The only remaining difference during build-time would be the eMMC size
Dec 17 10:25:49 <qschulz> lfa: do à la RPi with resizing of the partition at runtime?
Dec 17 10:28:00 <lfa> qschulz: thanks for RPi pointer. Will look at how they do it
Dec 17 10:35:35 <qschulz> lfa: I don't know if they do it in Yocto though, but raspbian and others do for sure
Dec 17 10:36:02 <rburton> fairly simple, grow the partition table then grow the file system
Dec 17 10:37:13 <rburton> systemd actually has a service built in to grow file systems, but it can't do partitions too.  probably worth sending a patch to them to do the partition table too...
Dec 17 10:52:15 <yocti> New news from stackoverflow: Unable to start bitbake server <https://stackoverflow.com/questions/48132054/unable-to-start-bitbake-server>
Dec 17 11:34:37 <stuom185> anybody using chromium? Any way to get rid of that "getrandom indicates that the entropy pool has not been initialized" message at startup?
Dec 17 11:35:05 <stuom185> I mean it doesnt start before it gets some entropy (mouse movement etc)
Dec 17 11:40:42 <rburton> get some entropy in your pool
Dec 17 11:41:01 <rburton> a lot of boards have a hardware rng you can hook up
Dec 17 11:43:12 <crazy_imp> hi, what should i look at if fetching of an ssh+git source fails? if i run the git ls-remoto command with all the variables set by the fetcher in a normal shell, it looks fine, but bitbake complains about being unable to parse the HEAD revision
Dec 17 11:46:43 <kroon> stuom185, rburton, I got a stalling sshd on boot once, nowadays I think sshd RRECOMMENDS "rng-tools" in order to help with the entropy
Dec 17 11:46:52 <rburton> right
Dec 17 11:46:55 <rburton> its a brute force hammer
Dec 17 11:48:37 <rburton> i've been meaning to remove that and get BSPs to add it if they need it
Dec 17 11:49:17 <stuom185> thanks, I'll look into rng-tools
Dec 17 11:50:37 <rburton> first look at your hardware
Dec 17 11:51:08 <stuom185> there is /dev/hwrnd but what to do with it
Dec 17 11:51:08 <rburton> you might just need to pass a kernel argument to get it working nicely
Dec 17 11:51:13 <rburton> what is the hardware?
Dec 17 11:51:22 <stuom185> hwrng i mean
Dec 17 11:52:16 <stuom185> toradex colibri imx8x
Dec 17 11:59:02 <rburton> http://main.lv/writeup/kernel_dev_hwrng.md is a useful resource
Dec 17 12:26:18 <rburton> stuom185: assuming https://github.com/torvalds/linux/blob/master/drivers/char/hw_random/imx-rngc.c is the driver then maybe a fix like https://github.com/torvalds/linux/commit/62f95ae805fa9e1e84d47d3219adddd97b2654b7 is appropriate?
Dec 17 12:38:13 <stuom185> rburton thanks for looking into it. I will take a note of these if I will need them later. It looks like it's way over my head though, I was hoping more like some --dont-ask-about-entropy flag for chromium haha.
Dec 17 12:38:46 <rburton> the problem is deeper: you have *no* entropy on boot
Dec 17 12:38:53 <rburton> rng-tools will bandaid it
Dec 17 12:40:03 <stuom185> So far only chromium seems to care about that. Is there something bad about rng-tools?
Dec 17 12:41:18 <rburton> no, its just that for some hardware it isn't needed
Dec 17 12:41:30 <rburton> (if the kernel does the right thing)
Dec 17 12:41:44 <rburton> thus that omap patch: one line to tell the kernel to use the driver out of the box
Dec 17 13:47:12 <LetoThe2nd> ndec: *sigh* andreea skipped my typo in the mail - can you edit a tweet she made?

Dec 17 14:16:15 <Crofton|road> LetoThe2nd: 1630 is new start time?
Dec 17 14:22:42 <LetoThe2nd> Crofton|road: it was always the start time, but it seems that this was only in my head
Dec 17 14:22:55 <Crofton|road> Ah :)
Dec 17 14:23:43 <Crofton|road> Dodn't forget to mention https://pretalx.com/oe-workshop-2020/ please
Dec 17 14:23:53 <LetoThe2nd> Crofton|road: yeah i've got it mentally noted.
Dec 17 14:24:38 <Crofton|road> I'll try and watch and remind you if you slack off
Dec 17 14:26:06 <LetoThe2nd> "if"?

Dec 17 15:41:47 <wertigon> I have gotten an image with psplash up and running and now I want to replace the image
Dec 17 15:42:00 <wertigon> But merely replacing it seems to not do anything

Dec 17 16:07:02 <rburton> wertigon: did you change the png, or the generated source
Dec 17 16:07:21 <rburton> wertigon: you need to re-generate a header from the png
Dec 17 16:09:05 <wertigon> I did regenerate the .h file
Dec 17 16:09:18 <wertigon> And copied it
Dec 17 16:09:41 <wertigon> Thinking a cache problem somewhere, but nvm... Time to go home for today
Dec 17 16:09:58 <wertigon> I'll do a clean rebuild during the night and see if that solves my problem :)
Dec 17 16:10:50 <wertigon> My problem btw, image showing up is a bit large, so I want to shrink it somehow
Dec 17 16:13:11 <wertigon> Anyway; see you tomorrow!

Dec 17 16:21:24 <kanavin> rburton, how does one actually build a devupstream variant of a recipe?
Dec 17 16:21:42 <kanavin> I tried lttng-modules-devupstream, devupstream-lttng-modules, nothing seems to work
Dec 17 16:22:04 <kanavin> lttng-modules-devupstream:target, devupstream:target-lttng-modules
Dec 17 16:25:52 <LetoThe2nd> Crofton|road: was that enough advertising?
Dec 17 16:26:02 <Crofton|road> Yes
Dec 17 16:26:11 <Crofton|road> having the link in chat should be great
Dec 17 16:26:54 <LetoThe2nd> Crofton|road: for reasons unknown we seemed to only have a handful of viewers today. no idea why.
Dec 17 16:30:12 <LetoThe2nd> actually thought that finding out why things happen is an interesting topic for most users ;-)
Dec 17 16:33:32 <Crofton|road> Maybe the time issue?
Dec 17 16:33:44 <Crofton|road> holidays? people are already slacking off
Dec 17 16:34:18 <LetoThe2nd> yeah timing is really a problem for me these days.
Dec 17 16:35:49 <LetoThe2nd> anyways. off then!
Dec 17 16:36:02 <kergoth> I'm half asleep and unproductive today
Dec 17 16:46:20 <rburton> kanavin: it makes an identical recipe clone with a different PV
Dec 17 16:46:30 <rburton> kanavin: so set PREFERRED_VERSION
Dec 17 16:46:51 <kanavin> oh, I see
Dec 17 17:50:42 <khem> armpit: I took the qemuppc64 machine conf from one of your layers, it does not boot linux-yocto 5.2 though ,should it ?
Dec 17 17:52:26 <armpit> I have not touched it in years so I have not idea what state it is in
Dec 17 17:53:23 <RP> khem: ask zeddii about mips64 ;-) I'd hope ppc64 is in better shape
Dec 17 17:53:57 <khem> armpit:ok
Dec 17 17:54:05 <khem> RP: yeah heh
Dec 17 18:06:42 <kanavin> rburton, usage of devupstream badly breaks 'devtool upgrade'
Dec 17 18:06:50 <kanavin> it gets confused between the two variants
Dec 17 18:26:23 <kergoth> that's odd, it should know what's preferred and what isn't
Dec 17 18:26:35 <kergoth> keying off of filename only perhaps
Dec 17 20:50:09 <mischief> what's the right way to override /etc/sysctl.d/99-sysctl.conf from procps?
Dec 17 20:52:39 <khem> mischief: via a bbappend provide your own and add it to do_install
