caisongAnybody know something about AGL CIAT-meeting yesterday? There is no message or mail about it.08:59
leon-anavicaisong, keep in mind that in the US they have already switched to daylight saving time so meetings might start in a different time depending your location's time zone.09:01
leon-anaviI missed a meeting yesterday because I didn't calculate the daylight saving time shift in the US :)09:01
*** toscalix has joined #automotive09:02

wesamhey, I see that I have 107gb of files in my build/tmp/work folder12:29
wesamis there a way i can decrease that cause my machine is full12:30
CTtpollardwesam: look for the inherit rm_work option for local.conf12:36
CTtpollardit will be documented in the yocto manuals12:36
*** caiortp has joined #automotive12:37
*** gunnarx has quit IRC12:38
wesamCTtpollard: would that delete all the stuff in work?12:41
CTtpollardwesam: 'yes'12:42
wesamCTtpollard: lol that was self explanatory, thanks12:42
CTtpollardif you have a populated sstate-cache & downloads dir it should be able to handle high level changes to the image without the need for the old work contents though12:42
CTtpollardwesam: basically the inherit tells bitbake to remove the work dir for package when it's no longer needed during the build process12:43
wesamcan I just delete the work directory outright12:49
wesambecause i am at the last part of building the image and I cant finish because of no space12:49
wesamI already deleted everything in my downloads and my sstate-cache12:50
CTtpollardthen no, that will cause everything to be rebuilt12:51
CTtpollard& redownloaded, etc12:51
wesamright12:51
wesami should of never deleted the sstate-cache12:51
CTtpollardsstate & download are the most valuable directories when doing multiple builds12:52
CTtpollardof the same systems anyhow12:52
wesamoh12:53
wesamgood to know12:54
wesamlol12:54
wesamwell I will get this build to finish and redo the whole build tonight12:54
CTtpollardwesam: The yocto documentation is good, if you plan to do continuous builds I advise you take a look. pre/own-mirrors is also a useful variable for speeding up local builds12:55
CTtpollardalso the documentation for parallel & bb threads12:56
wesamCTtpollard: it is, I used it to make my bb file. I will read through the documentation for everything else12:57
CTtpollardand of course #yocto upstream channel12:58

leon-anavizeenix, gunnarx I have just created GDP-575 for upstreaming the patch for rvi_lib.16:40
*** _corrupt has joined #automotive16:45
*** rajm has quit IRC16:47
wesamhas anyone got oprofile working on AGL16:53
RzRwesam, isnt it a regular linux kernel (+LSM) ?17:01
*** gunnarx has quit IRC17:07
zeenixleon-anavi: \o/17:10
*** rstreif has quit IRC17:11
*** Taha has quit IRC17:15
*** dunderroffe__ has quit IRC17:19
wesamRzR: im sorry, isnt what a regular linux kernal17:25
wesamoprofile is a profiling tool17:26
RzRyea it relies on a kernel module17:27
RzRyou need to enable this option, on which board are you working ?17:27
wesamintel minnowboard17:27
RzRyour CPU needs counters17:27
RzRso you have it17:27
wesamhow would i enable17:28
RzRjust make sure to have CONFIG_OPROFILE enabled17:28
RzRmake menuconfig :)17:28
RzRor the yocto way, using kernel's fragments17:28
wesamin what config file?17:28
CTtpollardor check if it's already enabled (I usually zcat the config gz)17:29
khemFor RPI users vc4graphics + X + kernel 4.9 fails but 4.4 works fine on master yp17:29
khemif you use userland graphics then its ok17:30
wesamRzR: can you explain where i should enable CONFIG_OPROFILE17:31
wesamCTtpollard: i tried looking for it but i dont have the operf command17:32
khemoprofile is ancient,17:32
khemmay be perf is better perhaps17:32
smurraythe newest version of oprofile essentially uses the perf api's anyways17:33
wesamkhem: lol you arent the first one to tell me this17:33
*** jlrmagnus has joined #automotive17:33
wesamI am looking into perf right now17:33
*** murphy has joined #automotive17:40
RzRwesam, anyway you'll need to enable options in kernel17:40
RzRhere is an example17:40
RzRhttp://git.yoctoproject.org/cgit/cgit.cgi/meta-oic/tree/recipes-kernel/linux/linux-yocto_3.19.bbappend17:40
*** murphy42 has quit IRC17:41
*** dunderroffe__ has joined #automotive17:44
wesamso i should write a bbapend to get it working?17:46
wesamand do something like KERNEL_FEATURES += "CONFIG_OPROFILE = 1"17:47
CTtpollardwesam: can you check zcat /proc/config.gz | grep $whatyouwant first?17:51
wesamCTtpollard: sure17:52
wesamCTtpollard: i just get this17:54
wesamshould i add CONFIG_OPROFILE=y17:54
wesamijust get this CONFIG_OPROFILE_NMI_TIMER=y17:56
CTtpollardso the only option grep is finding is 'CONFIG_OPROFILE_NMI_TIMER=y' if so then yes you need to add  CONFIG_OPROFILE=y to the kernel config, via bitbake most probably17:57
*** Taha has joined #automotive17:57
