/**
|
|
|
|
* We want to share layer trees across thread contexts and address
|
|
|
|
* spaces for several reasons; chief among them
|
|
|
|
*
|
|
|
|
* - a parent process can paint a child process's layer tree while
|
|
|
|
* the child process is blocked, say on content script. This is
|
|
|
|
* important on mobile devices where UI responsiveness is key.
|
|
|
|
*
|
|
|
|
* - a dedicated "compositor" process can asynchronously (wrt the
|
|
|
|
* browser process) composite and animate layer trees, allowing a
|
|
|
|
* form of pipeline parallelism between compositor/browser/content
|
|
|
|
*
|
|
|
|
* - a dedicated "compositor" process can take all responsibility for
|
|
|
|
* accessing the GPU, which is desirable on systems with
|
|
|
|
* buggy/leaky drivers because the compositor process can die while
|
|
|
|
* browser and content live on (and failover mechanisms can be
|
|
|
|
* installed to quickly bring up a replacement compositor)
|
|
|
|
*
|
|
|
|
* The Layers model has a crisply defined API, which makes it easy to
|
|
|
|
* safely "share" layer trees. The ShadowLayers API extends Layers to
|
|
|
|
* allow a remote, parent process to access a child process's layer
|
|
|
|
* tree.
|
|
|
|
*
|
|
|
|
* ShadowLayerForwarder publishes a child context's layer tree to a
|
|
|
|
* parent context. This comprises recording layer-tree modifications
|
|
|
|
* into atomic transactions and pushing them over IPC.
|
|
|
|
*
|
2013-04-26 02:25:33 +04:00
|
|
|
* LayerManagerComposite grafts layer subtrees published by child-context
|
2010-07-22 01:17:33 +04:00
|
|
|
* ShadowLayerForwarder(s) into a parent-context layer tree.
|
|
|
|
*
|
|
|
|
* (Advanced note: because our process tree may have a height >2, a
|
|
|
|
* non-leaf subprocess may both receive updates from child processes
|
|
|
|
* and publish them to parent processes. Put another way,
|
2013-04-26 02:25:33 +04:00
|
|
|
* LayerManagers may be both LayerManagerComposites and
|
2010-07-22 01:17:33 +04:00
|
|
|
* ShadowLayerForwarders.)
|
|
|
|
*
|
|
|
|
* There are only shadow types for layers that have different shadow
|
|
|
|
* vs. not-shadow behavior. ColorLayers and ContainerLayers behave
|
|
|
|
* the same way in both regimes (so far).

|
|

|
|
|
|
* The mecanism to shadow the layer tree on the compositor through IPC works as
|
|
|
|
* follows:
|
|
|
|
* The layer tree is managed on the content thread, and shadowed in the compositor
|
|
|
|
* thread. The shadow layer tree is only kept in sync with whatever happens in
|
|
|
|
* the content thread. To do this we use IPDL protocols. IPDL is a domain
|
|
|
|
* specific language that describes how two processes or thread should
|
|
|
|
* communicate. C++ code is generated from .ipdl files to implement the message
|
|
|
|
* passing, synchronization and serialization logic. To use the generated code
|
|
|
|
* we implement classes that inherit the generated IPDL actor. the ipdl actors
|
|
|
|
* of a protocol PX are PXChild or PXParent (the generated class), and we
|
|
|
|
* conventionally implement XChild and XParent. The Parent side of the protocol
|
|
|
|
* is the one that lives on the compositor thread. Think of IPDL actors as
|
|
|
|
* endpoints of communication. they are useful to send messages and also to
|
|
|
|
* dispatch the message to the right actor on the other side. One nice property
|
|
|
|
* of an IPDL actor is that when an actor, say PXChild is sent in a message, the
|
|
|
|
* PXParent comes out in the other side. we use this property a lot to dispatch
|
|
|
|
* messages to the right layers and compositable, each of which have their own
|
|
|
|
* ipdl actor on both side.
|
|
|
|
*
|
|
|
|
* Most of the synchronization logic happens in layer transactions and
|
|
|
|
* compositable transactions.
|
|
|
|
* A transaction is a set of changes to the layers and/or the compositables
|
|
|
|
* that are sent and applied together to the compositor thread to keep the
|
2013-04-26 02:25:33 +04:00
|
|
|
* LayerComposite in a coherent state.

2013-04-26 02:25:33 +04:00

|

|
|
|
|
* out to the Layer.
|
|
|
|
*
|
|
|
|
* - a Layer has painted new pixels. Its ShadowableLayer calls one
|
|
|
|
* of the Painted*Buffer() methods above with the back buffer
|
2013-04-26 02:25:33 +04:00

|

* descriptor. This notification is forwarded to the LayerComposite,
|
2010-09-14 09:23:08 +04:00

* which uses OpenDescriptor() to access the newly-painted pixels.
|
2013-04-26 02:25:33 +04:00
|
|
|
* The LayerComposite then updates its front buffer in a Layer- and
|
2010-09-14 09:23:08 +04:00
|
|
|
* platform-dependent way, and sends a surface descriptor back to
|
|
|
|
* the ShadowableLayer that becomes its new back back buffer.
|
|
|
|
*
|
|
|
|
* - a Layer wants to destroy its buffers. Its ShadowableLayer
|
|
|
|
* calls Destroyed*Buffer(), which gives up control of the back
|
|
|
|
* buffer descriptor. The actual back buffer surface is then
|
|
|
|
* destroyed using DestroySharedSurface() just before notifying

|
|
