| racarr | in this little demo shell the application switcher event filter is constructed from in the_event_filters from, but needs to get the_frontend_shell() hich needs the_input_focus_selector() which needs the_event_filters() ;) | 00:01 |
|---|---|---|
| racarr | hmm. I don't think I have moved more than 15 feet since tvoss went to sleep | 00:02 |
| thomi | ugh - as an interim hacky solution, benchmark data is being stored here: https://code.launchpad.net/~mir-team/+junk/benchmark-graphs - so please nobody delete that branch ;) | 00:13 |
| racarr | weird problems with my demo shell server configuration...seems the contents of my std::initializer_list are being lost in passing around | 00:53 |
| kdub | fbnativewindow defeats me another day :/ | 01:08 |
| racarr | aww | 01:09 |
| smspillaz | hmm, neat http://codicesoftware.blogspot.com/2013/04/put-your-hands-on-programming-language.html | 01:40 |
| smspillaz | language aware merge tool | 01:40 |
| RAOF | Hm. Interesting. Build Mesa with clang and Mir segfaults. | 02:11 |
| RAOF | Woot! | 02:23 |
| RAOF | We draw! | 02:23 |
| duflu | RAOF: Still building Mir with gcc? | 02:30 |
| RAOF | Yes. | 02:30 |
| RAOF | Fun fact: A radeon 5350 can't render mir_eglplasma at 1920x1200 at 60 FPS | 02:31 |
| duflu | RAOF: My first guess is accidental writes to const variables (which are memory protected under clang) | 02:31 |
| duflu | RAOF: I'll look at optimizations :) | 02:31 |
| duflu | RAOF: Oh. eglplasma is trying to do 1.3 billion single precision cosines per second :/ | 02:41 |
| RAOF | That's… quite a lot :) | 02:41 |
| duflu | RAOF: I've been thinking for some cases (like this) it may make sense to create a low-res surface and flag it as needing upscaling. The other case I thought of was simple games | 02:42 |
| RAOF | That's a part of the "fullscreen" request, isn't it? | 02:43 |
| RAOF | You say "make me fullscreen" with flags such as "and please change the output's resolution" or "upscale me if necessary" or etc. | 02:43 |
| duflu | RAOF: Yeah in the real world. Though some of our work-items are marked as DONE without such forethought :/ | 02:44 |
| duflu | I've been guilty of similar | 02:44 |
| RAOF | Oh, have we marked fullscreen as done? | 02:44 |
| duflu | RAOF: No, that one's in progress pending my state work | 02:44 |
| RAOF | <value optimised out> | 02:45 |
| RAOF | MY NEMESIS! | 02:45 |
| duflu | RAOF: What was your frame rate BTW? | 02:47 |
| RAOF | 40 FPS | 02:47 |
| RAOF | Which is not bad for a two-generations-ago low-power GPU. | 02:48 |
| duflu | RAOF: Hah. I call that a great success then | 02:48 |
| duflu | Hmm, we're out by two orders of magnitude. Best I can find, AMD advertise the 5450 as "Processing power (single precision): 104 GigaFLOPS" | 02:52 |
| duflu | Though it's likely that cosine takes many FLOPS | 02:53 |
| duflu | This might also be a limiting factor: Pixel fill rate: 1.6 Gigapixels - 2.6 Gigapixels/sec | 02:53 |
| duflu | I can't find specs for 5350. Seems to happen with all my graphics cards too. They're always so low-end that the manufacturer does not publish their existence | 02:54 |
| RAOF | You can find it on http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics_processing_units - it's an RV710 | 02:55 |
| RAOF | Which has specs around what you've listed. | 02:55 |
| RAOF | Hm. With -O0 I can see why clang's failing - the glFlush pointer appears to be garbage. | 02:58 |
| duflu | glFlush has a "pointer"? | 03:00 |
| duflu | To the context? | 03:00 |
| RAOF | The dri2_drv structure has a glFlush function pointer. | 03:01 |
| RAOF | ...which is populated via dri2_drv->get_proc_address("glFlush"), which is presumably the thing that's broken. | 03:01 |
| RAOF | ...which, in turn, is dlsym()'d from _glapi_get_proc_address | 03:02 |
| RAOF | And clang does throw a warning somewhere in the mapi/glapi build, so that might be it. | 03:03 |
| RAOF | And that suggests that the problem is not in *my* code, and we build mesa with gcc, so I'm going to call it good :). | 03:04 |
| duflu | Sounds a bit odd. Plain old C issues with clang should be easy to resolve. I surprised Mesa is not yet clang-friendly | 03:07 |
| RAOF | Oh, it's Wednesday! | 03:11 |
| RAOF | That means it's SRU DAY! | 03:12 |
| * duflu wonders if the SRU/SRY pun has been overdone yet | 03:19 | |
| thomi | behold: mir/glmark benchmark graphs: http://people.canonical.com/~thomir/ | 04:19 |
| thomi | errr... kind of hacky, I know | 04:19 |
| thomi | now the preasure is on RAOF to fix that bug in mir :P | 04:19 |
| thomi | err, mesa | 04:19 |
| RAOF | The pleasure's all mine! | 04:22 |
| racarr | https://bugs.launchpad.net/mir/+bug/1167133 this stuf is weird | 04:28 |
| ubot5 | Launchpad bug 1167133 in Mir "Input Filters fail to work when overriden through server configuration" [Undecided,New] | 04:28 |
| racarr | thomi: I see only 59 fps on one of the tests | 04:29 |
| racarr | I guess someone is to be fired. | 04:29 |
| smspillaz | isn't fps a bad metic ? | 04:29 |
| racarr | :p | 04:29 |
| racarr | yes | 04:29 |
| racarr | espescially when its capped to vsync ;) | 04:30 |
| thomi | right, so let's fix the vsync issue | 04:30 |
| smspillaz | I thought I read this article on arstechnica about measuring frame time | 04:30 |
| racarr | it's just a start | 04:30 |
| thomi | if anyone has any better ideas, I'm open to suggestions | 04:30 |
| smspillaz | racarr: the clear answer to this one is to just make mir hot-patch monitor firmware to make them refresh faster | 04:30 |
| smspillaz | "hey guys" | 04:31 |
| smspillaz | "my monitor goes at 50,000fps" | 04:31 |
| racarr | smspillaz: What do you think mir is doing no?? | 04:31 |
| racarr | w* | 04:31 |
| smspillaz | "all thanks to mir" | 04:31 |
| racarr | we stole the code from beryl | 04:31 |
| smspillaz | racarr: you stole code from norwood? | 04:31 |
| racarr | err...^H^H^H | 04:31 |
| smspillaz | oh sorry, norwood is the protocol | 04:32 |
| smspillaz | I meant northfield | 04:32 |
| smspillaz | you stole code from northfield | 04:32 |
| robert_ancell | duflu, you seem to have a very unreliable computer! | 06:04 |
| duflu | robert_ancell: It was working fine. Then I upgraded gtalk | 06:04 |
| robert_ancell | alf_, racarr, meeting? | 06:04 |
| alf_ | robert_ancell: ah, sorry I was waiting for a link on irc :) | 06:05 |
| robert_ancell | alf_, np :) | 06:05 |
| robert_ancell | kdub, ^ | 06:06 |
| RAOF | Aaah, hangouts :) | 06:12 |
| alf_ | robert_ancell: sorry, network died for a moment there | 06:22 |
| robert_ancell | alf_, :) | 06:22 |
| alf_ | thomi: btw, glmark2 prints frametime if you prefer to parse and display that (although you could also calculate it yourself easily) | 06:24 |
| RAOF | Only if we're not vsyncd :) | 06:24 |
| duflu | Argh. Stupid audio subsystem. Now looks like system-wide, my audio goes to/from the wrong devices and ignores my selection of devices to use. It worked last week... | 06:24 |
| RAOF | Wheee! | 06:25 |
| duflu | It's even broken in gnome-control-center | 06:25 |
| duflu | Oh, and my other headphones that would have worked recently disintegrated from age | 06:27 |
| thomi | alf_: yeah, I have frametime - if you think that's a better metric to use it'd be simple to switch | 06:55 |
| RAOF | alf_: Do we need nouveau support for use-dma-buf before landing it? I've got radeon support. | 08:46 |
| RAOF | Eh, I'll just implement nouveau support as well. It's not like it's hard. | 08:47 |
| mlankhorst | erm | 08:47 |
| mlankhorst | didn't I do that? :P | 08:47 |
| RAOF | mlankhorst: That was in xmir; it needs mesa as well. | 08:47 |
| mlankhorst | oh | 08:47 |
| mlankhorst | glxgears seemed to have worked though | 08:47 |
| RAOF | You probably didn't do that, because the gallium changes you need only just landed on github :) | 08:48 |
| mlankhorst | ok | 08:48 |
| RAOF | Yeah glxgears will work. es2gears_mir won't :) | 08:48 |
| alf_ | RAOF: Feel free to add nouveau now or leave it for later, I don't think it blocks anyone. | 08:48 |
| mlankhorst | it blocks meeeeeeee and I'm not a mesa developer | 08:49 |
| alf_ | RAOF: ^^ well I guess you have your answer ;) | 08:49 |
| mlankhorst | alright alright I'll poke mesa some | 08:50 |
| RAOF | mankhorst: Ok. I'll do nouveau as well and land use-dma-buf tomorrow. | 08:50 |
| mlankhorst | RAOF: I was sarcastic :P | 08:50 |
| RAOF | Probably a better idea anyway; landing in the morning means I can put out fires at my leisure during the day. | 08:51 |
| mlankhorst | i'll fix up nouveau and any bugs I come across myself | 08:51 |
| mlankhorst | just put it somewhere | 08:52 |
| mlankhorst | RAOF: ^ | 08:54 |
| RAOF | mlankhorst: github.com/RAOF/mesa - egl-platform-mir-dma-buf and mir-ppa. | 09:19 |
| mlankhorst | kk | 09:20 |
| RAOF | You need to implement whandle->type == DRM_API_HANDLE_TYPE_FD in bo_from_handle and bo_get_handle. See also: https://github.com/RAOF/mesa/commit/4deaa1bd5377e6224eb266f6a5c8e602f666aeff | 09:21 |
| RAOF | (You might notice the stunning kludge in that commit ) | 09:22 |
| mlankhorst | aw, installing some armhf packages removes some amd64 ones | 09:23 |

| mlankhorst | looks like my nexus 7 doesn't like mir either, I tried the instructions, but mir just crashes | 11:50 |
| mlankhorst | done with nouveau I think, I'm ignoring the GART stuff as it's unneeded with the kernel patches.. | 12:03 |
| alf_ | mlankhorst: for nexus 7, ping kdub, he should know more about what's up there | 12:03 |
| kgunn | mlankhorst: something about libhybris mods required only for nexus7 & only to egl...something about pthreads....platform team is workin' on it | 12:04 |

| mlankhorst | it's against the dma-buf branch but with debian from your ppa-dma-buf branch, which is why i disabled the egl-platform-mir patch | 12:43 |

| katie | racarr, how's it going? do you have time for a brief hangout? | 16:07 |

| racarr | kdub: more to xkbcommon-mapper too (I think the latest jenkins error there is a network quirk should be fixed soon) | 19:34 |
| racarr | fixed build in with FindXKBCommon.cmake :) | 19:34 |
| thomi | morning all | 19:54 |
| racarr | morning | 20:01 |
| robert_ancell | racarr, hello | 20:59 |
| kgunn | robert_ancell: hey...how did the team meeting go? | 21:35 |
| kgunn | robert_ancell: i literally woke up at 12:50 with no alarm....like an internal clock went off | 21:35 |
| robert_ancell | kgunn, we had alf, RAOF, duflu me and thomi there | 21:36 |
| kgunn | robert_ancell: i thot about joining....then thot better | 21:36 |
| robert_ancell | mostly did a round of "what we're doing" then talked about some CI stuff | 21:36 |
| robert_ancell | kgunn, good idea :) | 21:36 |
| kgunn | robert_ancell: bummer...no racarr or kdub? | 21:36 |
| robert_ancell | kgunn, no :( | 21:36 |
| * kdub is here | 21:36 | |
| robert_ancell | kgunn, we found it funny that we moved the meeting to a better time but had less people! | 21:37 |
| kgunn | kdub: past tense | 21:37 |
| kgunn | robert_ancell: and alan was out | 21:37 |
| kgunn | robert_ancell: so did you know what to do after leaving that prd review with richard? | 21:41 |
| robert_ancell | kgunn, I didn't think we had any actions other than to keep him up to date on planning changes | 21:42 |
| kgunn | robert_ancell: i suppose we did agree to split out mir into pieces...like, input support, system compositor, app copy/paste etc | 21:43 |
| robert_ancell | kgunn, the PRDs not editable by us right? | 21:43 |
| robert_ancell | kgunn, and those splits are reflected in the blueprints | 21:43 |
| kgunn | robert_ancell: prd isn't editable but the m2m planning one is.... | 21:45 |
| kgunn | i'm gonna take a crack | 21:45 |
| kgunn | i'll let you correct the damage :) | 21:45 |
| robert_ancell | kgunn, heh :) | 21:46 |
| thomi | I just finished configuring jenkins to graph mir autolanding build times. The result is: http://static.inky.ws/image/3841/showChart.png | 21:47 |
| thomi | tl:dr: it's getting longer | 21:47 |
| thomi | robert_ancell: got a minute? | 22:01 |
| robert_ancell | thomi, sure | 22:01 |
| thomi | robert_ancell: so WRT the lightdm autolanding, we need to hack the packaging stuff a bit. Lots of the PS projects have started using inline packaging, which makes it easier to keep the packaging & source code synced | 22:02 |
| thomi | so I could either propose a MP that adds the debian/ dir to lp:lightdm, *or* I could make a new branch: lp:lightdm-team/lightdm/trunk-packaging | 22:02 |
| thomi | it's up to you :) | 22:02 |
| robert_ancell | thomi, yeah, I'd prefer the packaging was separate as lightdm is used outside of ubuntu | 22:04 |
| thomi | robert_ancell: sure, OK. | 22:04 |
| thomi | I think there's some script that strips out the debian/ dir for "upstream" releases for Unity... but that's some deep juju that I have nothing to do with | 22:06 |
| kgunn | robert_ancell: hey is duflu going to propose his surface state stuff this week? (curious) | 22:10 |
| robert_ancell | kgunn, I though he was but I'm not 100% sure. I'll ask today | 22:10 |
| thomi | robert_ancell: any chance you could add me to the lightdm-team so I can push these packaging branches to be owned by that team? | 23:01 |
| robert_ancell | thomi, what's you LP id? | 23:01 |
| thomi | thomir | 23:01 |
| robert_ancell | thomi, done | 23:02 |
| thomi | thanks | 23:02 |
| RAOF | PSA: I've pushed the use-dma-buf mesa changes and marked use-dma-buf as approved. In the period while these things are not in sync, Mir EGL will not work. | 23:10 |
| RAOF | And by that I mean "Mir clients won't be able to use EGL" | 23:10 |
| racarr | robert_ancell: Merr...sorry...forgot about IRC. | 23:18 |
| racarr | ripping the InputDispatcher controller stuff (for focus) out of the InputManager to fix a focus bug to make my demo shell work :) | 23:18 |
| racarr | I made a demo shell that fullscreens everything and adds and alt tab keybinding but it crashes when you cycle focus because | 23:21 |
| racarr | the second time a window is made focused the way we recycle the android window handles in set_input_focus_to | 23:22 |
| racarr | causes the InputChannel to be destroyed and recreated...closing the fd | 23:22 |
| racarr | triggering an assert! | 23:22 |
| racarr | So it seemed like a good time to just go ahead and bite the bullet and implement the proper focus selection where the dispatcher controller maintains a list of all the window handles (this is what is needed to enable picking for touch input as well) | 23:23 |
| racarr | but then it became a refactoring spiral | 23:23 |
| racarr | haha | 23:24 |
| racarr | almost done | 23:24 |
| racarr | RAOF: Do you think you could do another review of https://code.launchpad.net/~robertcarr/mir/enable-inprocess-egl/+merge/155888 to override Alf's need's fixing (was fixed yesterday) | 23:41 |
| racarr | kevin approved so I think if you are ok with it we can land it | 23:41 |
| RAOF | racarr: Sure | 23:41 |
| racarr | Would like to land it so I can do a software cursor example | 23:41 |
| racarr | (a really funny one ;)) | 23:41 |
| racarr | kdub: Does this mean anything to you https://jenkins.qa.ubuntu.com/job/mir-android-raring-i386-build/337/console | 23:43 |
| racarr | err, loaded question maybe :p but you know what I mean | 23:43 |
| kdub | racarr, no unfortunately :/ | 23:44 |
| racarr | hmm | 23:45 |
| racarr | ill try a rebuild in an hour or so and maybe it will fix itself | 23:45 |
| racarr | if not investigate deeper | 23:45 |
