Summary: Forward to component transfer filter to WebRender → Forward component transfer filter to WebRender
Assignee: nobody → tnikkel

This just gets the data into webrender, it was a huge headache. Still need to actually write shaders to do the work.

Check point to see if I've done something horribly wrong.

Attachment #9036875 - Flags: feedback?(jmuizelaar)

Can you write a summary of your approach?

Flags: needinfo?(tnikkel)

We use a WrFilterData on the C++ side to hold the filter values (and function types), it's just a collection of pointer/size pairs for the values. We change the thing we pass around in C++ from nsTArray<FilterOp> to WrFilterHolder which contains a nsTArray<FilterOp>, nsTArray<WrFilterData>, and a nsTArray whose sole purpose is to own the memory for the values in the nsTArray<WrFilterData>.

The format for stacking contexts in the built display list goes from

PushStackingContext item
push_iter of Vec<FilterOp>

to

SetFilterOps item
push_iter of Vec<FilterOp>
1st SetFilterData item
push_iter of array of func types
push_iter funcR values
push_iter funcG values
push_iter funcB values
push_iter funcA values
.
.
.
nth SetFilterData item
push_iter of array of func types
push_iter funcR values
push_iter funcG values
push_iter funcB values
push_iter funcA values
PushStackingContext item

We need separate a SetFilterData item for each filter because we can't push_iter a variable sized thing.

When we iterate over the built display list to flatten it we work similarly to how gradients work with a SetGradientStops item before the actual gradient item. So when we see SetFilterOps or SetFilterData we use them to fill out values on the built display list iterator but don't those items return them to the iterator user and instead continue iterating until we hit the PushStackingContext item, at which point to the iterator consumer it appears as those the FilterOps and FilterDatas were on the PushStackingContext item. (This part is trickier too since we need a TempFilterData type that just holds ItemRange's until we get the actual bytes later.)

This gets the data all the way to where we construct the PictureCompositeKey. I'm not sure if we can just stick all these vecs on the PictureCompositeKey or not because I haven't looked at how it is used yet.

I guess the reason for making this non-Copy is because there is now a Vec stored in the composite mode enum, is that right?

I'll leave some comments in the other patches with a possible alternative way to store the data. If that works / makes sense, we could keep this enum as Copy, and remove these clone calls.

Also, I think in at least some of these cases in this patch, the clone call should not be required - but that may not be relevant if we change how the filter data is stored.

I'm not sure about having this as a separate enum variant - can it just be part of PictureCompositeMode::Filter? We already differentiate in the batching match statement on some specific filter types (e.g. blur and drop shadow).

We might be able to avoid this by skipping creation of this composite mode filter much earlier in the flattening step, if the filter data is empty?

Instead of this nested match, perhaps we can move this common code into a function, and pass a closure, or something similar to that.

Maybe this could just return a bool or something like that if it's valid, to avoid cloning the heap allocated vec.

This loop can probably be simplified quite a bit if we're able to use the interning logic mentioned below.

I haven't totally thought this through, but I think there might be a better way to structure the way we pass FilterData through WR, which would resolve the need to have a Vec in the PictureCompositeMode enums etc.

We have this interning infrastructure, which we use for primitives and clips. It allows us to store some arbitrary amount of data, and then get a unique handle for it that identifies the content. If we were to introduce an extra interner for storing the filter data, then the PictureCompositeMode enum would effectively just store a handle to that interned filter data. An added advantage of this, if it works, is that the GPU cache handle for the table data would remain across new new display lists, which would save us invalidating and uploading GPU cache data for the filter each time a new display list is received.

It'd be great to add a small number of wrench reftests for this functionality too (unless I missed that in one of the patches I didn't look at).

If we make it part of PictureCompositeMode::Filter then that means we need to store whatever data we need in a FilterOp, but FilterOp is shared with C++ (it didn't use to be so we could go back to that), and I don't think we can put the required rust data into a struct that is shared with C++.

This is what all the filters do in the general filter arm of the match just before this, so I just went along with that.

I thought about this, we'd still need an if at least to determine which closure to use. And separating it out into a separate function seemed like it would make the code harder to understand. I can try again if you have an idea that might work.

I tried getting that to work, the FilterData that we need to sanitize comes out of a vector, so moving out of that doesn't work. I'm probably missing something about how to do this properly in rust?

In future, we might want to store these as quantized fixed point values. This would give better cache hits in the interner if values are slightly different due to FP accuracy, and would also mean there's no need for a manual Hash impl below. But this can be done later on, no need to do it now.

Instead of checking for None here, we could restructure this slightly so that instead of None if identity, the continue is placed there. Then the _ branch won't need the Some(..).

It's still not totally clear to me why this is separate from being inside the FilterOp enum. But it's not a big deal - we could land as-is and consider changing this as a follow up.

Why do we need to add Hash/Eq to this?

We put FilterDataHandle (== intern_types::filterdata::Handle) into the PictureCompositeKey enum and the PictureCompositeMode enum. PictureCompositeMode has PartialEq, and PictureCompositeKey has PartialEq, Hash, Eq. So we need PartialEq, Hash, Eq on Handle and Epoch since it's in Handle. Is there a better way to do it?

Yup, at least in theory. If what I've written below doesn't make sense / or doesn't seem easy to make work, let me know and I'll take a closer look or we can discuss the details on IRC.

The current problem is roughly that:

The PictureCompositeKey is hashable so that we can identify pictures that have the same content / filters, for purposes of invalidating cached tiles etc. If we store intern::Handle in that, the cache key will often change, because intern::Handle has items like an epoch in it, that get updated per-frame.

What we ideally want to do (and I'm not sure if there's gotchas here) is:

  • Store the unique identifier of the filter in PictureCompositeKey. We can do this by calling handle.uid(). This returns the constant part of an interned handle that uniquely identifies the interned content. The ItemUid returned by that method implements Hash and Eq, so that it can be used directly in PictureCompositeKey.

  • It should be fine to store the full handle in PictureCompositeMode enum, I think. This enum doesn't need to be hashed, so it doesn't have those strict requirements. The current PictureCompositeMode enum does require PartialEq, but I just tested locally and that's not actually needed (it compiles if I remove it). So hopefully, if you remove PartialEq from PictureCompositeMode, you should be able to store the intern::Handle in there.

The part that I'm a bit uncertain on is whether the first change above might mean that the complete handle is not currently available where/when the PictureCompositeMode enum is constructed. If that's the case, we might be able to fix that by using the extra scene data struct that's available for interner use (which is currently a () in your patch)?

This diff works. Seems far too easy. Maybe I'm missing something.

don't add PartialEq, Hash, Eq to interning structures

Add interning structure

So if I combine this with the last patch undoing the PartialEq, Eq, Hash from the interning structures, are you okay with this?
Attachment #9045161 - Flags: review?(gwatson)

Yup, ship it!

PictureKey contains a Picture so we need to increase it's size expectation too.

For some reason this fixes the wrench reftest on Windows (works fine without this change on linux/mac). I don't understand it. Is this sane?

compute component transfer function type always

Review of attachment 9046228 [details] [diff] [review]:
-----------------------------------------------------------------

It seems like there's two possibilities here:

1) We're hitting a driver / ANGLE shader compiler bug. If we can determine that's the case, landing it like this is fine - but we'd want to add a comment to the shader describing why the code is like this, so someone doesn't change it. The comment should reference an entry that gets added in https://github.com/servo/webrender/wiki/Driver-issues.

2) Maybe there's a bug in the shifting / values of the funcs that get ORed in to the Op that is only showing up on Windows. It seems unlikely, but perhaps worth logging out of the CPU code the exact int values that are being passed in batch.rs, just to confirm they are as you expect?

The original failure was because there is a test to make sure shaders contain a default case for all switch statements. The test isn't smart and it just string matches "switch" and "default:" even in comments, since I used the word switch in a comment this caused it to fail.
