jonoRAOF, do you know what the status is on the ATI blocker that is blocking Mir from updating in the archive?05:04
RAOFjono: It's being frustrating and awkward.05:04
jonoRAOF, I can imagine05:04
jonostill blocked I presume05:05
RAOFBut it's not actually an ATI blocker; it's an IPC problem that only appears on that machine for some reason.05:05
jonoRAOF, do you think we should hold off the call for testing for the packages in the archive until this is fixed?05:06

duflumlankhorst: How to force it higher?07:25
mlankhorstso trust me if it's stuck on 30 fps07:25
mlankhorstit's because of a double vblank path07:25
mlankhorstthe only times boot speeds have given me issues have been when I was running real 3d applications, not the compositing manager :P07:27

dufluDear radeon: Give me an error, or display my buffer. Doing neither is not very friendly.09:00
alf__duflu: is this with the dmabuf fix applied?09:01
duflualf__: I have no idea what you mean. But I have tested up to kernel 3.10.6 and get the same bug09:01
duflualf__: What is it? What does it do?09:02
alf__duflu: dmabuf fix = fix for not pinning video buffers to system memory that mlankhorst was working on09:02
alf__mlankhorst: does 3.10.6 contain the dmabuf pinning fixes?09:03
duflualf__: Yeah mean for nouveau? Yes tested that and it works. But no luck with radeon... though I can't test kernel 3.11 with radeon due to other errors09:03
mlankhorstalf__: 3.11 does, which is in the archive09:04
mlankhorstI don't think it qualifies for stable, but it can be backported if you care09:05
duflualf__: Yeah I ran into that on nouveau and confirmed 3.11 works. You mean a similar fix is required for radeon?09:05
alf__duflu: yes, it's a dmabuf issue affecting both nouveau and radeon09:06
duflualf__: OK. I just gave up trying 3.11 on radeon due to strange errors. I'll have to go back to it09:06
alf__duflu: what problems do you get with 3.11?09:11
duflualf__: I saw odd Mesa/kernel errors and then full system hang. But that was raring + 3.11 kernel. I will try saucy daily image now...09:13
dufluIt's difficult when I can't upgrade this machine to saucy yet, and it's the only one I can put video cards in09:13
alf__duflu: why can't you upgrade?09:14
duflualf__: It's my "stable" server/desktop09:14
alf__duflu: perhaps have an partition for unstable installations?09:15
duflualf__: Perhaps. But that's a last resort09:16
alf__duflu: btw, I have a radeon, so if you want me to try something with saucy + 3.11 I would be happy to09:17

mterryracarr, heyo!  Got a sec to talk about mir sessions in u-s-c?  I'm testing on my nexus4 and the_shell_session_container() seems empty (yet mir/lightdm/u-s-c seem to be up and I see things on the screen).  What populates that list?  (seems to be sessionmediator in mir, but not sure what calls its connect() method)16:28
alan_gBRB - I've broken VT switching, need to restart some stuff16:40
=== alan_g is now known as alan_g|EOD
racarrmterry: the protobuf_message_processor17:25
racarrbut if things are working the session container is almost certainly being filled17:26
racarryou could check for open session, etc, well "connct" with17:26
racarrperhaps, you are getting the_shell_session_container in a weird way17:26
racarri.e. if you just store the CAchedPtr return value17:26
racarrwell, you need to hold17:26
racarra strong reference to it17:26
racarror you might end up with two17:26
mterryI got disconnected, resending in case I was already timed out...18:27
mterry<mterry> racarr, sorry, was away for lunch18:27
mterry<mterry> racarr, it seems that it's filled from platform-api.  So apps themselves might fill it...  but I think the shell/greeter aren't.   Not sure if they should or even if I'm reading the situation right18:27
racarrmterry: Ah ok18:28
racarrit's filled from the RPC layer as basically18:28
racarrthe session is like connection or something18:28
racarrthere is no session for shell/greeter surfaces.18:28
racarri.e. inprocess18:29
mterryracarr, but don't they act as a client for the u-s-c?  I'd think they'd call mir_connect to connect to the system mir18:29
racarrno, so18:30
racarrwe don't have nested mir at the moment, but lets say we did and then18:30
racarrthere is USC, which iwll jjust hve one session18:30
racarr"session mir"18:30
racarrand the session mir has application sessions, and shell surfaces, etc.18:30
racarrin the session mir18:30
racarrthe shell surfaces, are all inprocess clients18:30
racarrso there is no mir_connect, and no session18:30
racarrthere could be a session of some sort invented I guess. haven't come up with a usecase/sensible way to do it so far18:31
mterryracarr, shell surfaces are inprocess clients to what?  To their own mir servers?  But aren't they also clients to the u-s-c?  So they'd do a mir_connect to it, I would have thought.  I guess I'm missing how u-s-c views the shell surface, if it doesn't think of them as a client session...18:35
racarrmterry: u-s-c never sees shell surfaces18:35
racarru-s-c just sees18:35
racarrgreeter, maybe bootsplash and stuff like that, and one surface18:36
racarrfor each user session18:36
mterryracarr, ok, sorry.  I guess when I said 'shell surface' I meant user session surface18:36
racarroh ok like the whole18:36
mterryracarr, so greeter/user should be registered as sessions in u-s-c, right?18:36
racarrshould be in the_session_container yeah18:36
racarrbut, we don't have nested mir at the moment so you couldn't actually do that right?18:37
mterryOK, I'm not seeing that now.  So somewhere that's being messed up (and may be my own patches...)18:37
mterryracarr, we don't have nested mir?18:37
mterryracarr, how is u-s-c supposed to work then?18:37
mterryjust xmir?18:37
racarryep just xmir18:37
racarrnested mir is still in progress18:37
racarrsome parts of it started to land18:37
mterryracarr, ok.  So maybe I'm still getting ahead of myself.  :(   /me is eager to try to test whole system integration with a split greeter on phone18:38
racarryou could use little Qt apps that display a picture as fake session clients of u-s-c18:39
racarrto get things going18:39
racarrit just wont be as satisfying lol18:39
mterryracarr, well, I'm actually able to get the greeter and shell to be run by lightdm18:39
mterryracarr, but they don't seem to talk to u-s-c at all, and I can't switch between them18:39
racarrI don't know what exactly is going on byt my guess is its just18:40
racarrtwo entirey seperate mir servers18:40
bschaeferhmm there seems to be a recent memory leak in: mir_connection_create_display_config19:58
