10:26 <lynxeye> Uh, I think I finally got a clue on what's going on with the xwayland ts sharing issue. It's again (mostly) not caused by the sharing itself, but is fundamental issue with resource maps and their interaction with TS.

10:27 <lynxeye> So another fundamental bug exposed by this series.

11:04 <mntirc> oh wow

11:04 <mntirc> bug in mesa or xwayland?

11:11 <lynxeye> etnaviv mesa driver bug

13:19 <mntirc> lynxeye: complicated to fix?

13:29 <lynxeye> mntirc: If my mental model is correct then the thing that needs fixing should be reasonably straight forward. Just a lot of intricate resource state details to consider, so it needs to be done quite carefully with a good audit across the whole driver.

17:09 <sravn> lynxeye: I have full faith in your mental model :-) Glad to see that you are on track to find the root cause of this bug. Around the corner awaits the next bug surfaced by ts sharing...

20:22 <marex> sravn: the whole etnaviv driver seems flaky and seems to need a lot of work on it ... sigh

20:34 <sravn> marex: It is a pleasure to follow all the effort put into etnaviv recently. I am sure we will end with a driver that is in much better shape than one year ago

20:36 <marex> sravn: it would be nice if there was an actual community around etnaviv, but for that it would require at least some rudimentary documentation

20:36 <marex> and guidance for newcomers
