1297260 - Devise a testing strategy for GPU process restarts

Status: NEW

(Core :: Graphics, defect, P3)

Description

[David Anderson [:dvander] - inactive, e-mail if emergency]

We've never tested our device reset code on TreeHerder, and this is a good time to start now that we will have a very simple way of creating failures: we can kill the GPU process.

We don't just want to test that we can recover at the top of an event loop: we should be able to test the GPU process dying in the middle of an IPDL transaction, or while decoding video, or in the middle of a texture operation.

Normal unit or integration tests would be a good place to start.

Matt also mentioned a chaos mode on tree herder might help: We could randomly crash the GPU process during GPU entry-points and make sure we can recover to paint another frame.

Kevin, as I talked with david, this is another good practice to extend testing coverage of composition, especially with gpu process. Please have a look at it.
