smbppisati, We cannot be faulty. It must be the computer. ;)07:33
* ppisati should try to ditch pidgin and go back to... $whatever we ship07:33
apwppisati, for me my at-tab and dash invokations now take 20-40s to occur07:39
apwmorning all07:39
apwalt-tab07:39
ppisatiuhm no, alt-tab is still fast07:39
ppisatiandi admit i never use the dash07:39
smbapw, morning. always or only first07:40
apwoh i never use dash _intentionally_ but when i do now it freezes my desktop for 30s07:40
apwoh every time, always07:40
ppisatinope07:40
smbHm, ok. I only see a very long time the first time I bring it up07:40
ppisatistill fast07:40
ppisatieven the dash07:40
apwsmb, i am very glad i did not upgrade my desktop to daily-quality07:41
smbapw, Yeah, me too.07:41
apwmy main non-fixed workhorse agent57 is now in the scrap pile thanks to it07:41
apwi am pretty sure it is not kernel because that machine is one of the very boxes i test kernels on before upload07:42
ppisati"haswell i5 + ati gpu" box is ok07:42
smbawesome07:42
RAOFapw: Hm, sounds like the intel regression in mesa that I thought was fixed, then fixed again, and then fixed another time?07:42
apwand my typing useage style makes this bug immediatly obvious07:42
apwRAOF, need some of your bees back ?07:42
apwRAOF, how could i confirm ... this is a baby (read old) atom07:42
RAOFapw: Nah, that'd bee a tjaalton problem now :)07:42
apwheh :)07:43
RAOFOh, you're trying to use a 915?07:43
apwheh07:43
RAOF:)07:43
apwRAOF, so it cannot be ubiquitus can it, i think my other i915 is ok, i think07:44
RAOF??? :(07:44
smbapw, So maximegalon seems to come up with latest updates and that is a similarly old atom and i91507:44
apwi am upgrading another aom to the same level to see if it is affected too07:44
* apw parays this is not one of those "it could never have worked" bugs, the ones which only exhibit for me07:45
apwalso ... i have "blacker" cursors today, is that normal07:45
smbapw, mine is Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03)07:45
RAOFapw: Not normal, but you're not alone.07:45
apwmine is a D4xx/D5xx/N4xx/N5xx integrated ..07:46
apwRAOF, yeah i have inverted cursors07:46
smbapw, Hm... mine is not blinking and solid right now but seems bright enough07:47
tjaaltonapw: huh, so dash is slow for you?07:47
smbapw, tjaalton Oh great, mine is not slow ... it does not appear at all07:48
smbnow the whole dash turned grey07:48
smbapw, Something likely unrelated but maybe we should have a look: "perf samples too long (5012 > 5000), lowering kernel.perf_event_max_sample_rate to 25000"07:49
smbThose I think I remember appearing more often recently07:51
apwsmb, yeah the slower machines seem to say things about that, i assume it is benigh07:52
apwbut knowing would be good07:52
apwtjaalton, on that machine, yeah like hit alt, have nothing moving or changing but the cursor for like 40s07:52
apwthen it appears half filled, then wait a bit more07:52
tjaaltonnice07:53
apw35d by naieve counting == seconds07:53
smbapw, Ok, yeah, seems I have exactly the same07:53
apwthe launcher scrolls on just fine if i use meta+N to get to windows07:54
apwsmb, how is alt-tab07:54
smbThere is now a shadow dash07:54
smbHave not tried yet as it was so slow to even get the first thing up07:54

tjaaltoni'm looking at upstream changes since 9.108:09

tjaaltonwell, gen3 isn't that uncommon08:10

smbtjaalton, Ah ok, I just thought apw's netbook had something slightly newer than mine08:14
apwtjaalton, they are on gen7 inhouse i would think08:14
apwso that is 4+ versions older, "what are they"08:14
tjaaltonapw: probably so08:14
apwtjaalton, i am feeling retarded how do i find the exact GMA I have08:18

smbapw, a011 is 315008:19
apwcool, ok so smb is the same as the OR and i have added my chipset to the title08:20
apwsmb, could you 'affects me' on it08:20
smbapw, Hm, newer but looks like slower, less pipelines...08:20
smbapw, think I have08:21
apwok good08:21
apwsmb, title says 'me and one other' which would be the OR08:22
smbapw, mine says me and two other 08:22
apwsmb, i hate launchpad some days08:22
smbBut as the title changed to add your gma3150 I thnk we look at the same. :)08:23
apwoh i see, when you update one you have, it +1's the number _you_ have08:23
apwnot the actual number, POC08:23
apwtjaalton, i think you and i may have collided updating the title, and i may have bolloxed your update08:24
smbapw, Speaking of breakage... my FFE for Xen-4.3 in Saucy got approved over the weekend... :)08:24
* apw hates LP more08:24
* apw adds smb to the list08:24
* smb thought he was already on it in the tops region08:25
tjaaltonheh, I added [gen3] there now, it should cover it all08:25
apwgreat08:25
* apw moves smb up the list, rapidly08:25
smbAt least moving up ranks *somewhere*. Though on the "todo" list would be so much better. :-P08:26
apwsmb, can you test 'resume' performance on your gen3, i am finding a good 10s of "i am on, but there is nothing to talk to password wise" before i can use that box08:26
apw*down* on that one, *down* i say08:26
smbapw, I think that moves priority of what I can test as well08:27
apwbah, tuche' m'lord08:27
smbapw, suspend/resume seems to be ok (only one attempt)08:28
apwsmb, it works fine, it just seems reallly slow to let me start typing the password08:28
apwie the backlight comes on immediatly but gnome screensaver is not talking to me for ages08:28
smbapw, Yes, but no that looks good, too08:29
smbIt even comes up quickly without needing another keypress08:29
apwi guess that means there is something i can fix, perhaps something installed08:29
smbEither that or a slight difference between gma950 and 315008:30
apwyeah08:30
apwone or t'other08:30
smbWasn't that the machine that more often than the rest seemed to suffer from i915 problems08:31

Gsportwill linux ever be fixed?08:33
apwGsport, heh08:33
Gsportintel grafics suck08:35
* apw really hopes not, else there is no reason to pay me08:35
apwGsport, heh no i think it sucks as much as any other, just cause it is developed in the clear it is more obvious08:36
Gsporti have to respect your opinion i suppose08:36
GsportIMHO intel isnt dead it just deserves to die08:37
smbtjaalton, Ok, that environment variable override does work for me, too08:38
tjaaltongood08:38
apwGsport, i think someone who is willing to engage and share their data is to applauded, even if they are not the most powerful GPU makers08:46
apwit isn't like you have to buy their products if you don't like them, vote with your wallet08:47
apwtjaalton, ok that bug upstream implies that unity needs to adapt08:54
tjaaltoncould be08:56
* apw wonders what the recommendation is, pin mesa back or switch the environment08:56
* apw tries the env for completeness08:58
ppisatibrb09:02
apwtjaalton, confirming the /etc/environment thing here as well09:06
apwppisati, how utterly broken is calxeda09:51
apwgiven this is about the 40th patch we are applying for it09:51
apwtjaalton, i don't know if you saw the somewhat off topic comment in the bottom of the mesa bug, it seems the "unity puts the second screen in a place you can no longer render to it" bug is back (if they are accurate)10:17
apwhenrix, i see that kees fixes for those various CVEs are starting to trickle in via the HID tree10:36
apw(and i assume you have the same searcher i do to find them :))10:36

apwhenrix, heh i noticed when i went to add them :)10:37

hashkenI want to know if process virtualization is enabled in a particular kernel11:14
hashkenWhat flags should I check for in the kernel config file?11:15
apwhashken, what sort of virtualisation?11:15
hashkenI want to know if this particular kernel can support mininet - https://github.com/mininet/mininet11:17
apwhashken, do you mean lxc or something else11:17
hashkenA brief description of mininet from the github page11:17
hashkenMininet creates virtual networks using process-based virtualization and network namespaces - features that are available in recent Linux kernels. In Mininet, hosts are emulated as bash processes running in a network namespace, so any code that would normally run on a Linux server (like a web server or client program) should run just fine within a Mininet "Host". The Mininet "Host" will have its own private network interface an11:17
hashkenSwitches in Mininet are software-based switches like Open vSwitch or the OpenFlow reference switch. Links are virtual ethernet pairs, which live in the Linux kernel and connect our emulated switches to emulated hosts (processes).11:18
hashkenI am not exactly familiar with virtualization and stuff.11:18
apwso that sounds like it uses network namespaces and openvswitch, so i would expect that to work on later releases if anywhere11:18
apwas we keep pretty much up on the leading edge there for openstack and the like11:19
smbIt still would not be completely clear what feature is being looked for. Openvswitch in in the kernel and relatively complete in Saucy/3.11 11:22
smbTo run VMs is also supported in the kernels11:22
smbor containers11:23
apwyeah i am going on the page which that above snippet came from, which sounds like it is trying to use something lightweight to simulate many hosts, basically a cut down lxc as they are all under ones control and not malicious11:23
hashkenI am actually seeing if the raspberry pi kernel can support mininet11:26
hashkenSo, I actually need to know the kerenl config flags that are related to virtualization11:26
hashkenI have been able to find the flag fornetwrok namespaces - CONFIG_NET_NS11:26
hashkenBut, process virtualization is such a general concept, that I have not been able to find the relevant flags.11:27
hashkenSince you guys have a much better idea about the kernel than me, I am hoping that you will able to point out the appropriate flags to make mininet work.11:28
apwhashken, well indeed, there a are a lot, i would look at the init/Kconfig which has all the namespaces which are 'generic' listed, search for NET_NS11:31
smbhashken, This sounds like you are looking for a containerization, so probably a mix of cgroup and *_NS options11:31
apwand whether openvswitch is in the version you are using, harder to say11:31
smbHm looking at the readme and checkign with Saucy, there is a mininet package in the archive11:36
smbI would assume then this works with the stock ubuntu kernels11:37
smbhttps://github.com/mininet/mininet/blob/master/INSTALL11:38
smbStates the only requirement would be NET_NS11:38
smband openvswitch 11:39
KalozHi. I would like to ask for the merge of two bugfixes into the generic kernel for saucy. Who should I bug about them? ;)12:07
ppisatiapw: ah, i keept thinking the 'disable module check' + abi bump are enough12:17
smbKaloz, If those fixes are upstream in Linus tree and picked up by upstream stable they will be in the Saucy kernel automatically at some point.12:17
ppisati*keep12:17
smbKaloz, When unsure you can point out the fixes on kernel-team@lists.ubuntu.com12:20
Kalozsmb: yeah, but as one of them breaks booting, if those fixes get late, saucy won't install12:21
Kalozsmb: do I have to subscribe there or is it internal?12:22
apwppisati, well that patch didn't disable the module check either12:22
apwor if it did it did it against the wrong abi12:22
smbKaloz, Ok, so for that one you should file a bug (if you have not already) with ubuntu-bug linux. The list is public and you don't have to subscribe. Just takes a bit longer then as you have to get trhough moderation12:23
ppisatiapw: no, it didn't12:23
apwKaloz, so you might email the kernel-team mailing list with the patches and ask for them as well, a bug always helps focus the mind12:23
Kalozsmb: there's a bug, but it seems $randomuser can set it to "Fix released" so I'm afraid it will stay below radar or be missed in the noise12:25
apwKaloz, if it isn't fixed change it back12:25
apwand ... what is the bug number12:25
smbKaloz, Right, and I would write the email in addition12:25
Kalozapw: okay, I'll wait for the second ones upstream submission and send mail to there12:25

apwi hate LP12:30
smbapw, Which lp does not care about. :-P12:30
smb+112:30
smbHm, that upstream report looks like that was CSM not working but EFI did?12:30
KalozEFI does, but only with the patch12:31
smbah ok, have not read through all comments12:31
Kalozotherwise LPSS makes the kernel puke and it happens before framebuffer gets initialized12:31
Kalozso one gets no output at all :P12:32
apwKaloz, that fix hasn't hit linus' tree as yet, so ... we are going to be resistant on picking it up12:32
apwin case it changes12:32
Kalozapw: well, it's surely affects the macs, but if you check the patch, it could fail on other systems, too.. I know it's queued for 3.12, but stable was added in CC -- no idea when Linus would merge it12:34

kamalbjf, I haven't looked at the nouveau thing yet ... feel free to handle it.16:25
bjfkamla, done16:26
rtgkamal even16:26
=== kamal is now known as kamla
=== kamla is now known as kamal
bjfhenrix, greg sob'd it, it must be good16:27
rtgbesides, its a staging driver....16:28
henrixbjf: rtg: agreed.. so we just keep it as it is and i'll try to keep an eye on other regressions on this driver16:29
bjfhenrix, no, let's go ahead and sru that fix and get it into this cycle16:30
henrixbjf: oh, ok. so... iirc the backport isnt trivial and i would rather revert the commit that introduced the issue then having an untested (possibly broken) fix.16:31
henrixbjf: but i'll have to look again to the fix (there has been a weekend since last time i looked!)16:32
bjfhenrix, ack, go for the simple fix if the backport is a pita16:34
henrixbjf: ack16:34

dave_hi, what should I use for grouper: "fakeroot debian/rules binary-omap4" (from https://wiki.ubuntu.com/KernelTeam/ARMKernelCrossCompile)18:18
rtgdave_, I use 'dpkg-buildpackage -d -B -aarmhf -us -uc'18:19
dave_rtg: I was trying this all weekend. It builds. But I can't deploy the zImage (via abootimg) on grouper. It won't boot.18:21
rtghmm, well that is a different issue18:21
dave_rtg: what am I supposed to do once 'dpkg-buildpackage -d -B -aarmhf -us -uc' is finished? How do I get the kernel (boot.img) replaced?18:22
rtgdave_, there is some abootimg magic that I can never remember. perhaps ogra_ does.18:23
ogra_just run flash-touch-kernel ... it should dtrt18:23
ogra_root@ubuntu-phablet:/# flash-touch-kernel -h18:24
ogra_usage: flash-touch-kernel [path to kernel]18:24
* rtg -> lunch18:24
ogra_(needs zImage|vmlinuz)18:24
dave_where does flash-touch-kernel come from?18:25
ogra_initramfs-tools-ubuntu-touch 18:26
ogra_it is preinstalled on the device18:26
ogra_(and undocumented on purpose :) )18:26
dave_yes, flash-touch-kernel is on the device. But how is that supposed to work? I can cp a zImage over and flash it on the device???18:27
ogra_yes18:28
ogra_adb push zImage /tmp/18:28
ogra_adb shell18:28
dave_let me try that18:28
ogra_flash-touch-kernel /tmp/zImage18:28
ogra_(you could also just install the .deb of your build, flash-touch-kernel will be called automatically if you do that18:30
ogra_)18:30
dave_(when I was trying to install my .deb files,  got an error msg saying smth like "cannot write to /system/.." or similar)18:33
dave_"flash-touch-kernel /tmp/zImage" does not work. My zImage is not good I guess.18:33
dave_"fastboot flash boot saucy-preinstalled-boot-armhf+grouper.img" and I'm back in business :-)18:35
dave_So let me see, 'dpkg-buildpackage -d -B -aarmhf -us -uc' should work on raring?18:35
rtgdave_, I build on precise using  gcc-4.6-arm-linux-gnueabi18:37
phillwHi, is the fix for bug 1218691 noteworthy to kernel team / bug-team / ubuntu+1 ?18:37
ubot2`Launchpad bug 1218691 in linux-firmware (Ubuntu) "Possible missing firmware /lib/firmware/radeon/KAVERI" [Low,Triaged] https://launchpad.net/bugs/121869118:37
rtgphillw, its benign (unless you have a Radeon that requires the Kaveri firmware)18:38
* apw gives up for the day18:38
dave_rtg: gcc-4.6-arm-linux-gnueabi is not available on raring. I am using 4.7 here. But I also tried on precise + quantal (chroot) with gcc-4.6-arm-linux-gnueabi. On quantal I can build complete. Maybe I should try that zImage with flash-touch-kernel...18:39
rtgdave_, we had trouble with 4.7 and higher. it would not produce a bootable kernel18:39
phillwrtg: in my tiny opinion, having the warning message still flag up is a pain and could lead to further bug reports. However, I leave it in your good hands :)18:40
dave_rtg: OK18:40
dave_rtg: precise and quantal both good?18:40
rtgphillw, I'm hoping the kaveri firmware is upstream by the time saucy releases18:40
rtgdave_, same cross compiler IIRC, so yeah it should be18:41
phillwrtg: is there anyone I should ask about https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1218691/comments/418:41
ubot2`Launchpad bug 1218691 in linux-firmware (Ubuntu) "Possible missing firmware /lib/firmware/radeon/KAVERI" [Low,Triaged]18:41
phillwit is there, just possibly needs a sponsor?18:42
rtgphillw, get the radeon guys to send a patch to Ben Hutchings <ben@decadent.org.uk> to include the Kaveri firmware 18:44
phillwrtg: do they have a channel? 18:44
rtgphillw, the linux kernel mailing list (which the radeon devs should know about)18:45
phillwrtg: thanks, will do :)18:49
dave_what is "build-generic-lpae" good for?19:18
apwdave_, larger memory systems (in arm land)19:25
rtgapw, what happended with you "giving up" for the day ?19:26
dave_am I supposed to use ./debian/build/build-generic/arch/arm/boot/zImage for grouper, or "./debian/build/build-generic-lpae/arch/arm/boot/zImage" ?19:28
rtgdave_, I think you're not building from the right branch19:28
dave_git clone git://kernel.ubuntu.com/ubuntu/ubuntu-saucy.git19:29
dave_git checkout -b grouper remotes/origin/grouper19:29
rtgyou should be building from the grouper branch (which does not contain an lpae flavour)19:29
dave_huh?19:29
rtgwell, that looks right wrt  the branch name.19:30
dave_well, I just tried a new "./debian/build/build-generic/arch/arm/boot/zImage" and it still doesn't boot on my grouper19:32
dave_how would I skip building drivers, if I'm in a hurry?19:33
dave_(I'm a little more familiar with the AOSP build process)19:34
dave_Looks like I was indeed not on the grouper branch.19:37
dave_woah, I'm in19:43
dave_rtg + apw: thank you. "which does not contain an lpae flavour" was solving it for me :)19:46
rtgdave_, cool19:47
dave_...and "flash-touch-kernel /tmp/zImage" is helpful info. But I need to master abootimg too. Thank you!!19:47
rtgdave_, as for skipping drivers, there really aren't any shortcuts because of debian packaging.19:48
rtgnuless you _really_ know what yuo're doing19:48
rtgunless*19:48
dave_aha. well, normally I do. I just made a mistake in my chroot. didn't have git installed... lalala19:50
dave_my I ask how long it takes for you to build, say, grouper from scratch?19:51
rtgdave_, 5-7 minutes on my 4-way 80 CPU server19:51
rtglonger on my laptop19:51
dave_"4-way 80 CPU"?19:52
rtgdave_, its kind of noisy too19:52
rtgoops, only 64 hyper-threads19:53
ogra_oh, cking is already gone 19:53
dave_rtg: are you honest?19:53
rtgogra_, of course. we chase him off every day at 5P19:54
ogra_ [    0.000183] Calibrating delay loop (skipped) preset value.. 13.53 BogoMIPS (lpj=67677)19:54
ogra_:)19:54
ogra_13.53 ... funny value for a 1.6 GHz CPU on boot 19:54
rtgdave_, processor: 6319:54
rtgvendor_id: GenuineIntel19:54
rtgcpu family: 619:54
rtgmodel: 4619:54
rtgmodel name: Intel(R) Xeon(R) CPU           X7550  @ 2.00GHz19:54
ogra_i'll try to catch him tomorrow then 19:54
dave_I admit it takes longer that 5-7 minutes on mine. But won't say how much.19:55
dave_boot.img via abootimg working also. Life can be good.20:05
* rtg -> EOD21:03
dave_Why no adb logcat during boot? Or is there a trick?21:48
ogra_during boot ?21:50
dave_yeah, link on that other OS, you know.21:51
dave_like21:52
ogra_no, we are not that other OS :) our logs live in /var/log 21:54
ogra_but you can use /system/bin/logcat to get logcat output from the android container21:54
ogra_(it isnt in PATH)21:54
dave_When this other OS is installed I can run "adb logcat" on my laptop and if the grouper is connected via USB I can watch it boot, from very early on. When I have Ubuntu installed, "adb logcat" shows nothing during boot.21:58
dave_Above, I was talking about the system log, not the kernel log. The kernel log can be watched during boot like so: adb shell cat /proc/kmsg (on the other OS). Maybe just a simple adb thing, that can be enabled?22:10
