This is killing Fennec nightly on every use of a canvas element. We should either back out the Android changes or properly serialize the relevant information in the parent and send it on process creation.
And when I say canvas, I really mean webgl canvas. Still, this is a topcrash.
Created attachment 572313 [details] [diff] [review] avoid calling GfxInfoBase::GetFeatureStatusImpl for now on Android this should remove this crash, according to the call stack. So... if we can't use this interface to query hardware information in the content process on Android, what do you think we should do to get that infomation? Query it from the chrome process and pipe it to the content process?

I think the best plan would be to query and send the information in the chrome process inside ContentParent::ContentParent, and keep it all under an #ifdef ANDROID.

I'm unable to repro this when I backout the patch. jdm: what hardware/setup are you using, and is there any other info you can give me to repro it? I'd also appreciate a more in-depth description as to how you think this should be dealt with properly.
I merely saw this topcrash on crash-stats, I didn't try reproducing it. I'm not certain it's worth solving properly, given that desktop e10s is on hold and mobile e10s is going away imminently on nightlies.
This is a problem that still has to be dealt with. It was caused by some additions I made to support blocklisting Android devices from graphics features (OpenGL Layers, WebGL, etc). Benoit wrote up a temporary fix for it, but I need to reactivate this code properly. Any info you can provide would be appreciated.
It looks like any content process which triggers a SetDimensions call on a webgl canvas should cause the problem. I outlined a plan to solve this properly in comment 4 - we send other bits of information to child processes already, so this would just be querying amd sending one more thing, then storing that data somewhere so that we don't need to hit the JNI for the feature status later.
Ok, I think I completely missed the e10s being phased out part. It sounds like based on that, there's no reason not to do these queries on a single process once this is done, i.e. the way we were already doing them minus the mistakes in handling SDK versions detailed in bug 700931.
Actually, it might remain necessary to solve this properly for content processes if B2G is planning to be using them, which I believe they are.
mwu tells me that Gonk doesn't care about this, so we can probably leave it be.
Ok, thanks for checking into that.
We should definitely fix this the "right way", if it's not incredibly difficult to solve generally. Rumors of the death of multi-process Gecko are greatly exaggerated, even if particular products (desktop Firefox) aren't planning on using it in the near future.
Ok, I will start looking into solving it correctly then. If anyone has any repro steps or additional information on it, please provide it as right now I can't repro it.
