Description Chris Lord [:cwiiis] 2012-02-04 03:46:07 PST
The patch in bug #717283 was checked in to enable other optimisations, but none of these optimisations are ready yet. On its own, this patch is possibly a slight performance decrease, and introduces unnecessary risk.

We should back it out until we're ready.

Unfortunately, other work was done inside this patch and on top of it, so the back-out patch is not entirely trivial. Patch incoming.

Backout ondemand tiling

This patch backs out on-demand tiling, but doesn't back out any of the other associated work/fixes (some initialisation memory leak fixes, checkerboard metrics)

I'm currently at FOSDEM and won't be back until Monday evening, so if this needs checking in before Tuesday morning GMT, someone else needs to do it.

I've marked both dougt and blassey as reviewers, but I only think it needs the one review, so whoever takes it, remove the other flags if you could please :)

Backout ondemand tiling

Lots of stuff here but I looked over it and there doesn't appear to be anything obviously wrong with it. Try run is also green, and I built it locally and it seems to work fine.

Backout ondemand tiling

[Triage Comment]
This is needed on aurora, but not beta. The code never landed there.

This backout should make the rendering performance on aurora match that on trunk and beta.
