1471704 - Enable tiling on Linux for P-OMTP

Status: RESOLVED WONTFIX

(Core :: Graphics: Layers, enhancement, P3)

Description

[Ryan Hunt [:rhunt] (on leave until early May)]

This will need to wait to see what issues we get enabling OMTP on linux.

In the meantime, here is a try run [1]. I see no issues, just the expected unexpected-pass/fail reftest changes.

OMTP has been enabled on linux for a bit and there are no obvious issues. I'll let it sit for the rest of this week and then put up a patch to enable tiling.

Comment 2

[Ryan Hunt [:rhunt] (on leave until early May)]

Another try run to make sure nothing has changed [1]. I'll put up the patch soon.

[Ryan Hunt [:rhunt] (on leave until early May)]

One other change, I ran into an assertion firing on try that seems to be related to a bad refcounting definition in CaptureTiledPaintState.

[Ryan Hunt [:rhunt] (on leave until early May)]

It seems my try runs were only running linux64 and missed these failures. They look fuzzy to me. I'll update the reftest annotation patch.

Comment 15

[Ryan Hunt [:rhunt] (on leave until early May)]

Here's a try run with updated reftest assertions.

Comment 20

[David Durst [:ddurst]]

If this was disabled in 1480139 for causing things (like 1477226), is it going to be re-enabled in 63?

Comment 21

[Ryan Hunt [:rhunt] (on leave until early May)]

No, there are no immediate plans to re-enable this. Someone would need to get the time to sort through the crashes, and there are higher priority things that need to be done.

Comment 22

[Eric Rahm [:erahm]]

Per 1480139, comment 8 it looks like this was a memory win.

Comment 23

[Eric Rahm [:erahm]]

This was a pretty big memory win, it would be nice to see it resurrected.

Comment 24

[Olivier Duclos]

All the blockers have been solved. Time to resurrect this!
