Sep 23 03:44:44 <Guest88924> Did anyone performance tests of running a program using a custom kernel created by yocto vs running over an unmodified ffos ?
Sep 23 03:45:16 <Guest88924> The thing is that I would like to see if yocto is useful to create images that performs better
Sep 23 03:48:16 <Snert> seems like the results of such performance testing would be so highly specific to your task at hand.
Sep 23 03:48:44 <Snert> meaning you'll have to do that yerself to get meaningful results.

Sep 23 03:49:18 <Snert> seems like the results of such performance testing would be so highly specific to your task at hand.
Sep 23 03:49:21 <Snert> meaning you'll have to do that yerself to get meaningful results.
Sep 23 03:51:16 <kergoth> yocto is a build tool, not magic. but yes, you'd have to do your own performance testing for whatever your needs are
Sep 23 03:51:30 <jaberme> Ahm. But then, Yocto can be (for example) to optimize a run. I mean, if I have a program running on a embedded device, using a typical kernel, may Yocto help me to reduce (editing some layers) to reduce the imagen size and performance? Or Yocto simply helps you to port OS to different devices? (thanks for your previous responses Snert
Sep 23 03:52:14 <jaberme> thx kergoth
Sep 23 08:30:13 <bluelightning> morning all]
Sep 23 08:38:29 <soderstrom> bluelightning: morning :)
Sep 23 08:40:26 <bluelightning> hi soderstrom
Sep 23 08:41:12 <soderstrom> bluelightning: how are you this morning? :)
Sep 23 08:41:32 <bluelightning> ok thanks, how about you?
Sep 23 08:43:31 <soderstrom> I'm perfectly fine afaik ^^
Sep 23 09:18:35 <Ulfalizer> what's the point of the packaging step? does the installation step make use of binary packages? is the target system expected to have a package manager installed and support dynamic updates that way?
Sep 23 09:19:40 <Ulfalizer> as in, what use is having e.g. a bunch of RPMs for the packages?
Sep 23 09:20:08 <neverpanic> The latter
Sep 23 09:20:22 <Ulfalizer> okay, thanks
Sep 23 09:20:31 <neverpanic> You can have $pkg installed and can install the debug symbols on demand, for example.
Sep 23 09:20:54 <Ulfalizer> ok, makes sense
Sep 23 09:32:43 <neverpanic> Ulfalizer: Great, looking forward to see you next week then :)
Sep 23 09:33:43 <Ulfalizer> neverpanic: ah, didn't realize it was you :P
Sep 23 09:33:44 <Ulfalizer> same :)
Sep 23 09:39:51 <rburton> Ulfalizer: and the former, the images are built from packages
Sep 23 09:42:37 <Ulfalizer> rburton: are those in e.g. RPM format though? i assumed it just fetched stuff directly from the working directory.
Sep 23 09:43:29 <Ulfalizer> or WORKDIR or whatever it's called :)
Sep 23 09:45:01 <rburton> no, it uses the packages
Sep 23 09:45:06 <rburton> rpm or deb or opk
Sep 23 09:45:14 <Ulfalizer> kk
Sep 23 09:45:24 <rburton> because the packages are where the metadata and postinst scripts and so on are
Sep 23 09:49:39 <Ulfalizer> 5.3.12. in the manual makes it sound like it's copying stuff directly out of the workdir, but maybe i'm missing something re. what do_install does
Sep 23 09:54:20 <neverpanic> do_install runs make install (or equiv) and puts files into a destdir, that will later be split into packages in do_package
Sep 23 09:54:54 <neverpanic> when building images, meta/classes/image.bbclass defines a task do_rootfs that uses the packages to build an image
Sep 23 09:55:58 <Ulfalizer> ah, okay, i think i'm following then
Sep 23 11:02:13 <raykinsella78> hi folks - how do I override default configuration files that ship with Yocto - like /etc/network/interfaces
Sep 23 11:02:50 <raykinsella78> I can do a bbappend, with my own version - but what will happen when it tries to copy over with it baulk?
Sep 23 11:14:46 <Crofton|work> raykinsella78, Like this: https://github.com/EttusResearch/meta-ettus/commit/da86e76d116798e386d073a18453aabb6179a09a
Sep 23 11:24:24 <blotunga> hi
Sep 23 11:24:38 <blotunga> I'm trying to build an archive using the instructions from here: https://wiki.yoctoproject.org/wiki/Building_your_own_recipes_from_first_principles#Build_an_example_package_based_on_a_local_source_archive
Sep 23 11:25:07 <blotunga> but I get: linux-yocto-custom.bb: Failure expanding variable do_patch: ExpansionError: Failure expanding variable SRCPV, expression was ${@bb.fetch2.get_srcrev(d)} which triggered exception FetchError: Fetcher failure: SRCREV was used yet no valid SCM was found in SRC_URI
Sep 23 11:26:08 <blotunga> the bb file looks like this: http://pastebin.com/56RLR20j
Sep 23 11:26:29 <blotunga> don't mind the hardcoded paths right now, i just want to see it run
Sep 23 11:26:36 <blotunga> any ideas why it fails?
Sep 23 12:25:01 <bluelightning> blotunga: because you are not using git you need to set PV to a value that does not include SRCPV
Sep 23 12:25:11 <bluelightning> or rather, does not include ${SRCPV}
Sep 23 12:25:40 <blotunga> bluelightning: since I'm a complete beginner, can you show an example?
Sep 23 12:26:14 <bluelightning> blotunga: the value you are setting in that recipe for PV is "${LINUX_VERSION}+git${SRCPV}"
Sep 23 12:26:19 <blotunga> ah
Sep 23 12:26:26 <blotunga> from the .inc file
Sep 23 12:26:27 <bluelightning> the fact that you have ${SRCPV} in there is what's causing the error
Sep 23 12:26:53 <bluelightning> no, it's in the recipe itself - i.e. what you put in pastebin
Sep 23 12:27:04 <blotunga> ah yes
Sep 23 12:27:12 <blotunga> because I was using it with git before
Sep 23 12:27:13 <blotunga> damn
Sep 23 12:28:22 <blotunga> and what should SRCREV be?
Sep 23 12:30:13 <_4urele_> Hi everyone,
Sep 23 12:30:48 <_4urele_> I'm using gstreamer, with libgstrtp, but i can't find symbols for libgstrtp...
Sep 23 12:31:20 <_4urele_> I can't find any libgstrtp-dbg
Sep 23 12:36:41 <blotunga> bluelightning: thanks, it seems to work
Sep 23 12:42:54 <raykinsella78> bluelightning: if a recipe has an existing do_install, how do I run something after it in bbappend ... I need to append another action.
Sep 23 12:43:13 <raykinsella78> do_install_append() ?
Sep 23 12:43:26 <bluelightning> blotunga: SRCREV doesn't need to be set unless you're fetching from a version control system such as git
Sep 23 12:43:32 <bluelightning> blotunga: great
Sep 23 12:43:35 <blotunga> ah ok
Sep 23 12:43:36 <bluelightning> raykinsella78: yes
Sep 23 12:50:57 <blotunga> i wonder where the sandbox/dev comes from when building: meta-sigma-arm    = "sandbox/dev:f8768497fcba507a23996f7833a5ed4a93a33f3f", is there some trace from the original git version someweher?
Sep 23 13:05:24 <raykinsella78> Currently 3 running tasks (708 of 2624):
Sep 23 13:05:29 <raykinsella78> god its taking an age
Sep 23 13:11:17 <raykinsella78> bluelightning: if I had SRC_URI reference to aproject/afile in a recipe and then the same file in a bbappend, will the original get ignored.
Sep 23 13:11:31 <bboozzoo> any ideas where updateme that appears in kernel-yocto.bbclass comes from and what it does?
Sep 23 13:13:03 <bboozzoo> s/updateme/configme/
Sep 23 13:13:47 <bboozzoo> or is it just a bitbake task name being called explicitly?
Sep 23 13:16:27 <maxin> bboozzoo: configme comes from yocto-kernel-tools ..
Sep 23 13:18:40 <maxin> bboozzoo:  Please have a look here: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-kernel-tools/tree/tools/configme
Sep 23 13:18:47 <bboozzoo> looking right now
Sep 23 13:18:59 <bboozzoo> so this is the place where config fragments get applied?
Sep 23 13:20:01 <maxin> bboozzoo: yes, this handles the kernel configuration part
Sep 23 13:22:12 <bboozzoo> hm, I'm trying to recreate something similar for linux-wandboard, came up with some inline python and simple cat $cfg >> defconfig loop, but it looks like configme does a lot more
Sep 23 13:22:38 <raykinsella78> folks is there anyway to show what receipes have a dependency on a specific package.
Sep 23 13:25:48 <maxin> raykinsella78: "bitbake -u depexp -g package-name" ?
Sep 23 13:26:18 <raykinsella78> maxim: does that not tell me the dependences of a given reciepe,
Sep 23 13:26:38 <raykinsella78> maxim: I want the reverse, a list of packages that depend upon it.
Sep 23 13:27:03 <maxin> raykinsella78: It has a "Reverse Depends" section as well..
Sep 23 13:27:55 <otavio> rburton: http://ci.ossystems.com.br/job/fsl-community-bsp-master-next_x11-imx28evk/837/console
Sep 23 13:27:58 <raykinsella78> maxin:  ok thanks I will take a look again
Sep 23 13:28:05 <otavio> rburton: my builde reproduced the error
Sep 23 13:29:45 <bluelightning> raykinsella78: sorry, could you explain what you meant re SRC_URI ?
Sep 23 13:31:03 <raykinsella78> bluelightning: say a given recipe has in its SRC_URI - recipe/files/afile
Sep 23 13:31:44 <raykinsella78> bluelightning: I then create another layer also with recipe/files/afile
Sep 23 13:32:01 <raykinsella78> bluelightning: with the afile from the second layer automagically override the first.
Sep 23 13:36:44 <bluelightning> raykinsella78: only if you have a bbappend for the recipe in that second layer containing FILESEXTRAPATHS_prepend := "${THISDIR}/files:" in the directory next to the files dir
Sep 23 13:37:56 <raykinsella78> bluelightning: perfects, thanks for the tip
Sep 23 13:40:46 <bluelightning> you'll see that more-or-less boilerplate line in a lot of bbappends
Sep 23 13:41:08 <raykinsella78> bluelightning: had it already, just didn't make the connection ...
Sep 23 13:41:45 <bluelightning> ah ok, fair enough
Sep 23 15:10:08 <NewbNeedsHelp> yocto is officially making me feel stupid.  I can't mount a thumb drive and I need to get files onto my wandboard.
Sep 23 15:11:24 <NewbNeedsHelp> I set up a tftp server and I am trying to connect to it from yocto.  When I run tftp on yocto I am told "Usage: tftp [OPTIONS] HOST [PORT]" but I can't get it to connect to the server (which is pingable from yocto)
Sep 23 15:11:50 <NewbNeedsHelp> what is the syntax to connect to the tftp server from yocto?  man tftp does not work
Sep 23 15:13:33 <kergoth> "can't get it to connect" is not useful information. if you're getting an error, than give us the error. that said, you aren't 'on yocto'. yocto is an umbrella project that includes many things, including poky, the linux distribution you're likely running on your board
Sep 23 15:24:17 <NewbNeedsHelp> so should I ask for help on #poky?
Sep 23 15:25:28 <NewbNeedsHelp> I'm sorry if I am dumb and asking the wrong question
Sep 23 15:27:20 <NewbNeedsHelp> I am not getting an error.  If I run "tftp 10.10.1.90:69" it merely tells me the usage.  I've tried just about every combination of commands that I can think of.  Unfortunately I don't know what the "OPTIONS" are
Sep 23 15:30:25 <NewbNeedsHelp> That worked.  Thank you for the help.
Sep 23 15:30:39 <NewbNeedsHelp> I think I'm good now.  You all are life savers.
Sep 23 15:44:57 * kergoth realizes he never submitted an oe selftest for recipetool-newappend and rolls eyes at self
Sep 23 16:04:18 <Ulfalizer> how can i get the DESCRIPTION text of a recipe via the bitbake tool?
Sep 23 16:04:54 <JaMa> bitbake -e recipe | grep ^DESCRIPTION=
Sep 23 16:04:55 <rburton> Ulfalizer: low-fi way is bitbake -e [recipe] | grep -e ^DESCRIPTION=
Sep 23 16:05:36 <JaMa> rburton: still working on v2 for ${B} issue?
Sep 23 16:05:45 <rburton> JaMa: yeah
Sep 23 16:06:01 <rburton> JaMa: there's a new race with do_populate_lic_setscene
Sep 23 16:06:14 <JaMa> k, just wanted to refresh it before starting new world build
Sep 23 16:07:41 <Ulfalize1> what's the last thing i wrote?
Sep 23 16:07:42 <rburton> urgh, enters task with a [dirs] set, minute later it does os.getcwd() and that throws file not found
Sep 23 16:07:59 <rburton> Ulfalize1: "how can i get the DESCRIPTION text of a recipe via the bitbake tool?"
Sep 23 16:08:21 <Ulfalize1> < Ulfalizer> maybe there isn't a one-to-one correspondence between the name you give to bitbake and .bb files, but work with me as i'm a noob :P
Sep 23 16:08:25 <Ulfalize1> i'll add that then. thanks. :)
Sep 23 16:13:51 <HoloIRCUser4> Gm
Sep 23 16:18:27 <raykinsella781> folks how do I specify a particular version of a recipe when more than one is available in my image file or at the command line?
Sep 23 16:18:43 <rburton> raykinsella781: set PREFERRED_VERSION in your distro or layer config
Sep 23 16:19:25 <raykinsella781> rburton: thanks keep forgetting that ...
Sep 23 16:25:57 <raykinsella781> Exception: NameError: global name 'imagetypes_getdepends' is not defined
Sep 23 16:25:58 <raykinsella781> odd
Sep 23 16:46:25 <Nilesh_> Hu
Sep 23 17:29:52 <cheeb> hi
Sep 23 18:09:01 <raykinsella781> how do I autoenable a systemd service when the image is being generated.
Sep 23 18:18:59 <kergoth> raykinsella781: see the SYSTEMD_AUTO_ENABLE variable in systemd.bbclass. in master/2.0 it's enabled by default, not sure about your version, you can examine the class to see it. set to a value of "enable" to enable it
Sep 23 18:21:43 <raykinsella781> kergoth: thanks got it!
Sep 23 18:34:22 <kergoth> RP: do you think we should move to using a stamp to indicate an out of date mirror tarball needs updating rather than removing it? I don't feel strongly either way. In theory it should only be removed if we successfully updated the clone in ud.clonedir.. i can see an argument that an out of date tarball is better than no tarball, but i can also see an argument that if you need a tarball for distribution, you should enable BB_GENERATE_MIRROR_TARBALLS=1
Sep 23 18:34:22 <kergoth>  and make it a nonissue..
Sep 23 18:34:36 * kergoth shrugs
Sep 23 18:35:23 <kergoth> and i forgot to cc bluelightning on a recipetool/devtool change again. i really need to get better about using Cc: headers in my commits
Sep 23 20:20:22 <RP> kergoth: BB_GENERATE_MIRROR_TARBALLS is set but we lost the tarball yesterday
Sep 23 20:20:57 <RP> kergoth: turned out that repo was quite damaged and revisions went missing so I'm not surprised the fetcher had a fit :/
Sep 23 20:21:21 <RP> kergoth: but it did delete the old tarball and fail to create a new one since the fetch failed due to missing revisions
Sep 23 20:27:16 <kergoth> Huh, I wonder what codepath triggered its removal. Afaict the recently added one should only have hit on successfully updating clonedir.
Sep 23 20:27:17 <kergoth> interesting
Sep 23 20:27:43 <kergoth> We really need to sit down and start delineating more ideas on cases that need adding to the unit tests, perhaps a wiki page to start with
Sep 23 20:58:37 <RP> kergoth: yes. I wish I could sit down with this and figure out what happened but I'm in full fire fighting mode right now
Sep 23 20:59:10 <RP> kergoth: I'd imagine force pushing a branch and then running a build against a removed commit and a new commit would do it
Sep 23 21:00:06 <RP> kergoth: <build rev A>; <force push B, replacing A>, <build rev B>, <build rev A>
Sep 23 21:11:17 <dasabhi> hey guys i compiled a kernel from scratch without bitbake
Sep 23 21:11:26 <dasabhi> and its operational on the board
Sep 23 21:11:36 <dasabhi> but i dont know how to ge the ethernet drivers working
Sep 23 21:11:51 <dasabhi> as in i cannot ping google at all
Sep 23 21:12:02 <dasabhi> and when i type ifconfig it doesnt even detect eth0
Sep 23 21:13:45 <dasabhi> any one know whats going on?
Sep 23 21:15:02 <Snert_> if up eth0
Sep 23 21:15:11 <Snert_> does nothing?
Sep 23 21:15:24 <dasabhi> it did something
Sep 23 21:15:28 <dasabhi> i see >
Sep 23 21:15:31 <Snert_> now do ifconfig
Sep 23 21:15:43 <dasabhi> nothing
Sep 23 21:15:58 <Snert_> eth0 exists but it has no ip addy?
Sep 23 21:16:02 <dasabhi> just returned >
Sep 23 21:16:26 <Snert_> hmmmm...okay beyond me.
Sep 23 21:16:29 <dasabhi> no thats not possible, when i use a different kernel it connects to ethernet
Sep 23 21:17:27 <xyzzy42> ifconfig doesn't show interfaces that aren't up by default.  ifconfig -a does them all, or specify an interface name to see it if it's up or not
Sep 23 21:19:37 <xyzzy42> if eth0 really doesn't exist, problem is almost always driver not in kernel or device tree incorrect
Sep 23 21:20:15 <dasabhi> xyzzy42: yeah that is the issue, the kernel doesnt have the drivers
Sep 23 21:20:39 <dasabhi> xyzzy42: thing is during cross compilation i don't know how to enable the right ethernet drivers
Sep 23 22:30:38 <malkauns> how do i add wireless-regdb to yocto?
Sep 23 22:30:57 <malkauns> is it a kernel config setting or a image feature?
