straycatssam2, As I understand it you can't bind two processes to the same port, I don't know of any way to have multiple services running on the same port.09:05
ssam2oh, that's a shame09:06
ssam2I wonder if there's anything else we can do to make it possible to use Morph on public wifi, then09:06
ssam2this limitation made it impossible to actually give a demo when I gave a talk about Baserock at the weekend09:06

ssam2I wonder if one lighttpd process could route requests to both cgit.cgi and morph-cache-server as appropriate09:08
straycatI guess we could do, that's what we do with gitano on http.09:13
straycatAhh except that the git stuff runs as the "git" user and the cache stuff runs as the "cache" user.09:19
persiaRouting different URIs to different engines from the same server on the same port is fairly normal.09:20
persiaOne way to get around the multiuser issue is to have the server instance proxy 127.0.0.1:8080 to some prefix, which ought just be a line of config somewhere09:21
*** franred [~franred@82-70-136-246.dsl.in-addr.zen.co.uk] has joined #baserock09:21
persia(if not, we can move cgit to 7080, and run any of the many lightweight frontend web servers to proxy both services at different prefices.09:21
KinnisonWe could go to a proper httpd which can handle multiple users, or as persia says, we can run a bundle of servers against localhost and then reverse-proxy from :8009:23
KinnisonCherokee is pretty easy to get to build09:23
KinnisonBut keeping the current separation might be better09:24
persiaThe aforementioned "proper httpd" does the same thing, just tries to hide it from users (and tends to use unix sockets rather than real ports)09:24
KinnisonCan use TCP too09:24
KinnisonCherokee is pretty flexible09:24
KinnisonNot that I'm an upstream on it09:24
Kinnisonahem09:24
Kinnison[* may not be true]09:25
KinnisonAnd I definitely didn't do the work to allow multiple uid/gid support while still dropping privs on the main process, oh no09:25
* persia doesn't really see the point of claiming to be a monolithic server than then proxying to oneself over TCP, but leaves that sort of architectural decision to proper upstreams of the relevant servers09:26
Kinnison:-)09:27
KinnisonHigh performance across a wide range of platforms often comes at the expense of architectural elegance :-(09:28

paulsherwoodrichard_maw: Did folks agree with my suggestion to merge franred's script on its own, then run it on master, and merge the result?11:26
richard_mawyes11:27
paulsherwoodcool11:27
paulsherwoodtvm11:27
* paulsherwood is excited :)11:28
radiofreethis 3.16 built the kernel in 27 minutes, 17 minutes slower than it should11:49
radiofreequite a lot of oops messages (relating to kernel) in the dmesg log as well11:50
paulsherwoodthat's not lovely11:50
radiofreethankfully since i upgraded it using baserock i can just reboot on 3.10 to build the artifacts11:51
paulsherwoodi've been building with 3.15 on x86 with no problems... but maybe i should try 3.1611:51
paulsherwooddo you think what you're seeing is jetson specific?11:52
radiofreepaulsherwood: this is a jetson issue11:52
* paulsherwood must try upgrading soon11:53
paulsherwoodhas anyone done any work to make for minimal size devel system? eg low-hanging-fruit stratum-splitting magic12:30
radiofreei'm hoping this fixes the kernel issue12:31
radiofreethe CPU_FREQ stuff doesn't appear to be very well implemented12:31
radiofreeso it was defaulting to ondemand (so a low clock speed) then crapping out when you try and do anything with it (i.e increase it), since the cpu0/cpufreq/ stuff wasn't being exported12:32
radiofreeforcing it to PERFORMANCE looks ok, but i'll know in about 7 minutes12:32
paulsherwood:-)12:32
paulsherwoodwhere are you setting that, radiofree ?12:33
radiofreein the kernel config12:33
radiofreeCONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y12:34
radiofreedoesn't look good12:46
paulsherwoodoh dear12:56
radiofreemove back to 3.1012:56
radiofreebut then docker might not work?12:58
paulsherwoodprobably not13:01
paulsherwoodradiofree: are you using the configs i added for docker? if so, maybe they are the problem?13:02
ssam2paulsherwood: haven't done any work for a minimal size dev system, would love to13:04
ssam2there's some issues with splitting that need resolving though, like the one I mailed the list about last week13:04
radiofreepaulsherwood: not that13:09
radiofreeit's the 3.16 kernel i'm building with the baserock config, no docker stuff in it13:10
radiofreecpu isn't maxed out13:10
paulsherwoodradiofree: so are you saying that 3.16 works nicely for graphics, but has issues for compile/build?13:18
radiofreeyep13:22
cyndisare you using 3.16 on jetson?13:34
pedroalvarezcyndis: I believe he is13:35
cyndisthen it is no wonder that cpufreq isn't working :)13:36
pedroalvarezradiofree: ^^13:36
cyndissince the series that adds it isn't yet even in -next, just on the ML13:36
pedroalvarezthat's good to know, thanks13:39
cyndisif you're interested in tegra support in the upstream kernel, please join #tegra. most of the devs are there.13:40
radiofreecyndis: thanks :)13:41
cyndis:) great to see that people are actually using it!13:42
cyndislots of patches in the pipeline at the moment13:42
paulsherwoodcyndis:  aha! :)13:44
paulsherwoodradiofree: ^^13:45

radiofreeany chance on getting another +1 on my tegra-3.10 merge?15:51

radiofreemore patches sent!16:47
richard_mawradiofree: I would have preferred the commit message say why we need to revert, but I overheard enough conversation to have a sufficient idea of the problem16:51
pedroalvarezradiofree: thanks for the example (max-jobs)16:53
pedroalvarezSeems like I need to set max-jobs to  in audiomanager16:54
richard_mawradiofree: +2, on the condition that you update the commit in your definitions change from 123cc68c33ff537748a244f4932640083b4b6825 to de3664efca390a8d2fe525a583d17772deee8500 (the merge commit)16:54
radiofreeok16:55
richard_mawlet me know when it's done, so I can include it in the morphology rearrangement patch16:57
paulsherwoodrichard_maw: do you mean the chunks-in-definitions rearrange? is that going live today?16:59
richard_mawthat's the plan16:59
radiofreerichard_maw: merged16:59
radiofreeerm16:59
radiofreeyes merged16:59
* paulsherwood can hardly wait16:59
pedroalvarezI wonder if I can get a quick review on this: http://pastebin.com/jabw6tz917:00
pedroalvarezor should I send it to the ML?17:00
pedroalvarezcurrently audiomanager doesn't build on a Jetson board17:01
richard_mawpedroalvarez: give it a few minutes, and include the audiomanager morphology change in definitions.git17:01
pedroalvarezoh! good to know!17:01
paulsherwoodradiofree: you missed my comment on your comment :)17:02
richard_mawpedroalvarez: is audiomanager running out of memory, or is the build-system failing to parallelise properly?17:02
richard_mawthe former is minor grumbling, the latter brings shame upon audiomanager's build system17:02
pedroalvarezrichard_maw: I believe it's running out of memory17:03
pedroalvarezOh, I managed to build it, it doesn't happens always :)17:03
paulsherwoodpedroalvarez: well +117:05
paulsherwood(better to fix it, avoid tripping up someone else in future)17:06

* pedroalvarez had an ERROR, but he forgot to upgrade his morph first17:15
