* ppisati wonders if they'll try to use nvidia's opensource tegra driver13:16
apwppisati, interesting13:17
ppisatiapw: /me wonders if we can use it for our phablet/nexus7 img13:20
apwppisati, indeed.  why don't you find out :)13:20
ogra_theiur opensource driver is for X, isnt it ?13:20
ogra_wont help on phablet13:20
ppisatiogra_: no idea13:21
ppisatiapw: don't think it's ready yet, but i can give it a look13:21
ogra_and i dont think it has full 3D support in X so wont be of much use on n7 desktop either13:21
ogra_phablet uses libEGL directly, thats the part they will never make free13:22
rtgapw, 'binary-arch-deps-$(do_libc_dev_package) += binary-arch-headers' is why headers are not getting packaged in the LTS backport build for Raring.13:26
apwrtg ?13:26
ppisatiogra_: "x11, drm, fbdev, and gdi" which backend do we use with libegl?13:26
apwrtg, how does that work in any version if that is true13:27
rtgapw, bug #113444113:27
ubot2`Launchpad bug 1134441 in linux-lts-raring (Ubuntu Precise) "kernel headers are missing from 3.8" [Undecided,In progress] https://launchpad.net/bugs/113444113:27
rtgapw, becasue we set that flag false for the LTS backport build13:27
apwrtg, obviously we don't want libc making back there though13:27
apwrtg, and how does it work in the quantal lts backport13:27
rtgapw, dunno, was just gonna go have a look13:27
apwrtg that change is nothing new13:27
apwrtg, and remember binary-arch-headers is in more than one place, depending on settings13:28
apwrtg, and binary-arch-headers is _not_ the headers for the kernel, that is only libc-dev13:29
rtgapw, well, hmm.13:29
rtgapw, what builds linux-headers*all.deb ?13:30
apwrtg,  install13:31
rtginstall-headers13:31
apwrtg, ie binary-arch13:31
apwrtg, so binary-arch-headers is only about libc-dev, binary/install et al all make the headers13:31
apwbinary-headers is a convienience for you as a human and not used internally iirc13:32
ogra_ppisati, gralloc13:32
apwrtg, search for "        # The flavour specific headers image13:32
apwrtg, this is on the raring backport branch right ?  13:34
rtgapw, yep13:34
* apw pokes13:34
apwrtg, any idea when we might see 3.8.1, cause this had is pissing me right off13:42
apwheap13:42
rtgapw, today according to his announcement13:42
apwas soon as you have it i want want want want *stamp foot* *cry*13:43
* apw is getting grumpy a losing his environment every other hour13:45
apwand this is too hard to reporoduce to be able to bisect it reliablly13:45
apwand not far enough apart to not be annoying13:45
apwrtg, not that there is any hope that it will be fixed by that, there is none of the flip fixes in there, bugger13:47
apwrtg, got it, its that -SRCPKG thing agian14:05
rtgyeah, I was just getting to that conclusion14:05
apwdh_installchangelogs -plinux-lts-raring-headers-3.8.0-714:05
rtgmust be in a control file14:05
* apw will sort it out14:06
rtgapw, k, I'll go back to the N7 kernel14:06
rtgapw debian.master/control.stub.in:Package: SRCPKGNAME-headers-PKGVER-ABINUM14:07
apwrtg, we're not using those in theory14:08
apwrtg, as we are on the branch14:08
apwand control is right actually as we make the right package name in the output14:08
apwbut we don't put the shit in the right place, so it is empty14:08
apwrtg, this is all because we don't let the indep package change name, which we should really do14:11
apwthese lts-backports packages are a bit of a mess ... arg14:11
rtgthe indep packages are unique because of the ABI number, right ?14:12
apwthey are for lts-backports _only_ because they don't overlap14:12
apwfor example in ppc they are not14:13
apwor indeed in the linux-lowlatency14:13
apwso we have to be very careful in changing the indep parts14:13
apw_or_ more likely we should be letting the indep package in the lts-backports be different14:13
rtgso you're thinking it _should_ be linux-lts-raring-headers 14:13
apwperhaps, we can discuss that at 'sprint', the important thing is for now we need to fix that14:14
apwbut only on the lts-backport branch14:14
apwnot in the master, as that is carried over to ppc and lowlatency14:14
* apw confirms this is the issue14:14
rtgapw, well, if we are going to change the name we need to do it before sprint14:14
apwrtg, will figure out the deps for ppc and lowlatency and propose somethign on kernel-team@14:20
=== bambee is now known as rperier
rtgack14:20
apwwe need the change i am having to revert there, so for now i'll do it on the branch14:20
rtgapw, policy on CONFIG_PATA_ACPI in raring is that it has to be 'y' or 'm', right ?14:50
apwyeah14:50
rtgI think it should _never_ be 'y'14:50
rtgas it will match any storage PCI ID14:51
apwrtg is it causing an issue? 14:58
rtgapw, bug #108478314:58
ubot2`Launchpad bug 1084783 in linux (Ubuntu Raring) "[Regression] SATA reset failing since Linux 3.6" [High,Fix committed] https://launchpad.net/bugs/108478314:58
apwrtg, if the description in that bug is right then indeed it should not be y, it being y is interesting it must have been switch that way for a reason, no idea why tho.15:00
rtgapw, I couldn't find one either. just thought you might know.15:00
rtgI'm gonna make the policy 'm'15:01
apwnope i dont recall, perhaps uni-cum ?15:01
rtgwtf is uni-cum ?15:02

rtgthat one ^15:46
rtgisn't that your build bot somewhere ?15:46
apwyeah it is a build bot jobby15:46
apwnow i get you, yo mean you uploaded just before seeing there was a .1 you could rebase to at the saem time15:46

rtgapw, did you have a patch for the raring LTS headers issue yet ?17:04
rtgapw, never mind. I fixed it.17:19
BenCrtg: when are you guys going to switch to using an upstream tar ball with 3.8?17:35
rtgBenC, usually just before handoff prior to release. guess thats coming right up.17:36
BenCOk17:37
rtgBenC, I'll try to remember it for the next upload.17:37
infinityBenC: Ah, wasn't around.  Oh well, you get adare.17:58
* rtg -> lunch18:26
apwrtg, you changed that indep thing on master-next in raring, that is the wrong place, that will break ppc et al18:39
rtgapw, you're sure ?19:03
rtgapw, ok, dropped that patch for now19:06
apwrtg, yeah they both have full header sets, including their own independant common header, to allow them to migrate britney independantly19:11
rtgapw, ok, I've just left it in the LTS branch19:11
unkle_georgeThis is more of a glibc/alloc thing, but maybe someonehere can explain it to me:  "deallocated space is not placed19:17
unkle_george on the free list for reuse by later allocations" http://man7.org/linux/man-pages/man3/mallopt.3.html19:17
unkle_georgeSo any allocations over 128k are not reusable by my app even after free?19:18
unkle_georgewhile(1) {delete [](new char[128*1024]);} will eventually exhuast memory space?19:19
rtghenrix, I think 'Re: [PATCH 018/139] tty: Prevent deadlock in n_gsm driver' on the kteam list is directed at you.20:07
rtgapw, pushed N7 again with some config updates. seems to work OK on the desktop.20:30
henrixrtg: checking20:31
henrixrtg: interesting, looks like we're not building that driver in with our config.20:33
henrixrtg: i need to take a closer look at that20:34
rtghenrix, you should likely be building vanilla stable with allyesconfig20:34
henrixrtg: i was testing with the same config we use for the mainline builds20:35
rtghenrix, which I beleive is derived from Ubuntu20:35
henrixrtg: most likely. i'll start doing that. thanks20:35
