08:46.48ant_workOOM (udevadm)
08:47.18anarsoulgood morning, ant_work
08:47.59anarsoulant_work: 32mb ram?
08:48.08ant_workno, 64
08:48.13anarsoulhmmm
08:48.37anarsoulmake sure that CONFIG_LEGACY_PTYS is disabled in kernel
08:48.57ant_workI have two suspects: 1) meta-oe may be adding smthg bad
08:49.18ant_work2) recent rework of udev recipes / compatibilty for systemd and sysvinit
08:49.19anarsoul2month-old build works ok on 64mb
08:49.38ant_workcore-* images built with oe-core only did boot ok
08:49.52ant_workcouple of weeks ago
08:50.13anarsoulanyway, check for CONFIG_LEGACY_PTYS
08:50.29ant_workit's funny how we battle wit the damned udev cache since years :/
08:50.55ant_workanarsoul: kernel has not changed, even I've removed stuff recentl
08:51.21anarsoulant_work: just check, those legacy PTYs eat too much space in tmpfs
08:51.40anarsoulwith this config enabled I'm not able to boot oe rootfs on rx1950 (32mb ram)

08:53.27ant_workanarsoul: changes in oe-core 9 days ago...hmmm
08:56.43anarsoulant_work: I still suggest you to check if CONFIG_LEGACY_PTYS is disabled.
08:57.04ant_workit is not explicitely enabled
08:57.34anarsoulcould you share your rootfs?
08:58.01ant_workyes but later, is on another machine
08:58.16ant_workfor armv4/collie you mean?
08:58.53ant_workI'm looking now at the recent commits playing withudevadm/udev_cache

09:12.10ant_workI remember having battled with it couple of times
09:13.00anarsoul:)
09:14.52ant_work<ant__in fact I'm thinking about dropping udev>
09:15.01ant_workreally, we could live with devtmpfs
09:15.36ant_worknow we have all the CGROUPS stuff just because of udev
09:16.05anarsoulyeah, we could
09:17.56anarsouludev on a device like this is just a waste of memory/cpu time

12:04.32ant_workdon't miss the Android vs. armv7 SWP thread
12:04.37ant_workif you have free time
12:04.47Crofton|worklakml?
12:04.48ant_workit's already 49 posts and it's 4th july
12:04.51ant_workyes
12:05.38ant_workhttp://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/268504.html
12:11.51broonieant_work: Relatively few of the people there are in the US!
12:17.52ant_work^_^
12:18.35ant_workbroonie: really one single patch over vanilla and Android boots? wow
12:18.43ant_workunexpected
12:19.59broonieant_work: Most of the trick is device support.
12:26.04ant_workCrofton|work: one of last RMK posts is even summoning Linus T.
12:26.11ant_workthat's th enuclear strike
12:26.12Crofton|workomg
12:26.26Crofton|workI saw ones where they suggested that would be like summoning Sauron
12:26.34ant_workhe he
12:27.00Crofton|workmru is arguing with rmk again
12:28.12ant_workyea, uncomfortable

12:33.51Crofton|worksomeone from .us should complain to rmk about arguing on a .us holilday
12:35.50mckoanCrofton|work: LOL
12:36.12Crofton|workas I recall someone mentioned he complained about people emailing on a weekend :)
12:39.56koenheh
12:39.57koenSWP
12:40.11koenthat was discussed at lenght during connect macau as well
12:40.18mckoanCrofton|work: I've got to know about his ways a bit 'rough' when I was working with StrongArm in 2002 ;-)
12:41.54ant_workarguing with him is a problem because he's mostly right ;)
12:43.09koen"Asking them all to
12:43.10koenrecompile is not feasible"
12:43.12koenhahahaha
12:43.26koenandroid sucks, news at 11
12:44.22Crofton|workI figure the handset manufacturers want you to replace your handset every year anyway
12:49.46koenand you still get a 2 year old android version with it
12:50.55ant_workI don't own any A. device atm but I guess when you upgrade the 'firmware' you upgrade both kernel + userspace
12:51.11ant_workor is it perverswely done?
12:51.51ant_workand for the apps in the store, well, how many stores? you can count on one hand
12:52.19koenthere are a lot of app stores
12:52.28koenbut only one official google store
12:52.36ant_workreally? didn't know
12:54.12anarsoulheh, it's expected that some old apps aren't work on newer device and/or firmware
12:54.33anarsoul(for Android, of course)
12:54.52ant_workApple is more drastic with that
12:55.02ant_workand the devices are much more expensive
12:55.11ant_work(in the past at least)
12:56.18ant_workpeople wanting to sell to owners of ios6 or ios7 had to recompile the older apps
12:56.31ant_workend
12:56.45anarsoulwhat I want to say is that there won't be armv8 android for already released versions of android
12:56.48anarsouli.e. for 4.4
12:57.13koenhttp://releases.linaro.org/14.06/android/images/armv8-android-juno-lsk
12:57.23koenthat's android64 4.4.3
12:57.27anarsoulthey'll probably release 5.0 for armv8, so it's ok to say to devs "you have to recompile your apps to make them work with android v5"
12:57.53anarsoulkoen: are there any android devices in production with armv8 cpu?
12:58.46koennone for sale
12:58.57koenthe only armv8 device you can buy is the iphone 5s
12:59.20koenthe server type stuff is still "call us, we'll give you a quote"
12:59.41koenmaybe in a few weeks you can buy armv8 phones in china
13:02.54anarsoulkoen: so it's only a matter of bumping sdk version or whatever they have
13:03.27anarsoulinstead of messing with kernel and introducing emulation of not-anymore-supported instructions
