| anpok_ | tjaalton: hm I am trying your vulkan binaries.. | 08:57 |
| anpok_ | and I have a problem within X .. | 08:57 |
| anpok_ | vkcube and other examples I pulled complain that there is no DRI3 support.. | 08:57 |
| anpok_ | but I actually rebuilt the most recent intel xorg video driver .. enableing dri2 in debian/rules.. | 08:57 |
| anpok_ | did I miss a step? | 08:58 |
| anpok_ | dri3 of course.. | 08:58 |
| anpok_ | stuff runs fin on top of drm/kms though | 08:58 |
| anpok_ | zzarr: any news form your endevaours? | 08:59 |
| zzarr | anpok_, it's hard to understand what parts of the kernel I need to make an Android container work/run | 09:01 |
| anpok_ | .. write a detailed description when you figure that out.. | 09:01 |
| anpok_ | i want to try that too next time i get some more free time.. | 09:02 |
| zzarr | right now it's more like if I figure it out | 09:03 |
| anpok_ | :) | 09:03 |
| zzarr | is there a more detailed block diagram of the kernel/libhybris and all of it? | 09:04 |
| zzarr | anpok_, what would be the best approach? trying with the Android driver or wrap the freon driver? | 09:08 |
| zzarr | if the question is not clear by wrapping the freon driver I mean making a Mir-server that runs on top of freon | 09:12 |
| anpok_ | zzarr: well you need to solve the problem of transfering a rendering result from a client to the server.. if the freon driver has capabilities to do that - then this will be the more intersting approach because you get to write some code.. | 09:15 |
| tjaalton | anpok_: you missed reading the ppa description :) | 09:16 |
| anpok_ | my (maybe outdated?) understanding of the chrome os rendering system is that they only have a single process doing the actual rendering with the gpu driver.. the other processes just use an inter process version of GLES/EGL and maybe some 2D drawing library | 09:17 |
| zzarr | anpok_, I think so too I would get a much deeper knowledge and it would work on any Chrome OS device (Intel/ARM alike) | 09:18 |
| anpok_ | zzarr: but yeah that would also be an interesting integration task.. let USC do all the rendering.. | 09:18 |
| anpok_ | tjaalton: yeah I am good at that | 09:18 |
| zzarr | anpok_, I'm still not familiar with all the terms, what does USC stand for *feeling like I should know* | 09:20 |
| anpok_ | unity-system-compositor the system compositor in the default ubuntu touch setup | 09:20 |
| anpok_ | usually the thing that posts to screen | 09:20 |
| zzarr | anpok_, okey | 09:21 |
| anpok_ | with kms/android drivers it just posts the buffer of the nested server to screen | 09:21 |
| anpok_ | so it is a process that runs a mirserver | 09:21 |
| zzarr | anpok_, is that a good approach here too? | 09:22 |
| anpok_ | what do you refer to: | 09:23 |
| anpok_ | ? | 09:23 |
| anpok_ | ah you mean having usc there too .. | 09:25 |
| anpok_ | yes you need something with the necessary permissions to access the gpu.. and the screen.. and you want to allow as processes as possible | 09:26 |
| anpok_ | thats actually even safer than with kms/android drivers.. | 09:26 |
| zzarr | anpok_, good call | 09:31 |
| anpok_ | *as few processes | 09:32 |
| zzarr | anpok_, could you help me figure out where to start? (I'm still new to graphics in general) | 09:37 |
| anpok_ | hm first I would try to figure out where and how chrome os sets up rendering with the drivers you have.. | 09:38 |
| anpok_ | then try to get that workin outside of chrome os.. | 09:38 |
| anpok_ | then take that as a basis for a mir graphics platform | 09:39 |
| zzarr | anpok_, Is the lack of console a problem or is that bypassed if I get freon running? | 09:39 |
| anpok_ | hm no i do not think so.. | 09:40 |
| anpok_ | it might just make stuff harder to try out :) | 09:41 |
| zzarr | I have a kernel with console right now, so I don't think that would hinder anything | 09:42 |
| anpok_ | i guess figuring those things out will keep you busy for a while ... then you have to look into getting the IPC services working.. | 09:51 |
| anpok_ | and after that you might have to make some changes to mir to get all of that working as a graphics platform | 09:51 |
| zzarr | IPC? | 09:51 |
| anpok_ | interprocess communication | 09:51 |
| zzarr | okey, yes | 09:52 |
| anpok_ | http://www.chromium.org/developers/design-documents/displaying-a-web-page-in-chrome | 09:52 |
| zzarr | thanks anpok_ | 09:52 |
| anpok_ | https://sites.google.com/a/chromium.org/dev/developers/design-documents/gpu-accelerated-compositing-in-chrome.. | 09:52 |
| anpok_ | oops | 09:53 |
| anpok_ | strip the last two dots | 09:53 |
| zzarr | thanks again :-) | 09:57 |
| zzarr | anpok_, the second link is a bit outdated, (Chrome OS used X back then, and Freon as of Q3/Q4 last year) | 09:58 |
| anpok_ | tjaalton: yay works.. | 10:00 |
| anpok_ | tjaalton: oh.. those demos at //github.com/SaschaWillems/Vulkan.git make the i915 reset the gpu in various ways.. | 10:04 |
| zzarr | anpok_, it's hard to find any info about how freon works | 10:06 |
| zzarr | anpok_, this might be interesting https://sites.google.com/a/chromium.org/dev/developers/design-documents/ozone | 10:08 |
| zzarr | Vulkan looks nice | 10:14 |
| alan_g | alf_: I'd like your eyes on this (as you wrote the original). I tried reverting the associated changes and this appeared reproduce the original failure, but it was hardly a clean merge so I can't verify I've captured the intent: https://code.launchpad.net/~alan-griffiths/unity-system-compositor/rework-DeadlockLP1491566/+merge/286698 | 10:16 |
| tjaalton | anpok_: which cpu? | 10:18 |
| alf_ | alan_g: ack, I will take a look | 10:21 |
| anpok_ | tjaalton: i7-4750HQ .. so haswell iris 5200 | 10:23 |
| tjaalton | anpok_: hmm might be a known issue then | 10:24 |
| anpok_ | there is an incomplete support warning on startup of each demo.. | 10:25 |
| anpok_ | zzarr: hm there was a mir port of that one once -- running ozone as a mir client -- not what you need as far as i can tell.. | 10:26 |
| tjaalton | yeah, the driver is in flux and moving stuff around upstream, so i haven't bothered updating it yet | 10:27 |
| zzarr | anpok_, I guess that I could have a look at that but only to get a general feel | 10:58 |

| zzarr | anpok_, is there an picture or description how the components communicate in Mir? | 12:17 |
| zzarr | I have found this, what parts don't I need? http://i1-linux.softpedia-static.com/screenshots/Mir_1.png | 12:20 |
| zzarr | If I ported QtMir and QtUbuntu, would that be enough? | 12:20 |
| alan_g | zzarr: as it port them to something other than Mir? | 12:21 |
| zzarr | or is it everything below libhybris? | 12:21 |
| * alan_g should probably read backchat | 12:22 | |
| zzarr | I guess I was thinking a bit wrong | 12:22 |
| zzarr | I should have the freon driver in the position where libhybris is now | 12:23 |
| anpok_ | probably.. | 12:25 |
| anpok_ | there is no nice colorful picture that guides you through the source code | 12:26 |
| anpok_ | you will have to provide an implementation of the mir::graphics::Platform interface | 12:26 |
| zzarr | anpok, the image I found as well as knowing that the interface mir::graphics::Platform is a colorful image ;-) | 12:28 |
| alan_g | zzarr: does this help? https://bazaar.launchpad.net/~mir-team/mir/development-branch/view/head:/design/Architecture.dia (You need dia to view it) | 12:29 |
| zzarr | I was about to install dia from the repository... but I could not... it says that it don't know about a package called "dia-gnome-gnome-gnome-gnome"... I suspect I know why | 12:33 |
| zzarr | alan_g, nice diagram | 12:41 |
