REGRESSION(320153@main) 2D context self drawImage performance regression
https://bugs.webkit.org/show_bug.cgi?id=323495
rdar://186731221
Reviewed by Matt Woodrow.
Upon creation, remote ImageBuffers would send their surface handle to
WCP. This would hold the underlying IOSurfaces in use, preventing
recycling through IOSurfacePool. For loops that do a lot of self draw,
this would cause IOSurface alloc/dealloc churn.
Fix by not sending the handles. This was a feature used when ImageBuffer
handles were attached to layers after compositing. Currently we use
ImageBufferSets for this. The only cases that the handle is currently
used is PlaceholderRenderingContext and view transitions. The feature
cannot be used effectively, as WCP->GPUP synchrous flush is needed
anyway before the handles can be attached to layers.
Due to this feature, the RemoteImageBufferProxy and ImageBufferBackend
were more complex than needed: the RemoteImageBufferProxy would need to
start without a backend. Upon operations that needed backend-specific
information, the access would block until the backend was available
through the handle transferring message.
Instead, instantiate the backend at the RemoteImageBufferProxy
instantiation site. For cases that can map the backend backing store,
shared memory and in-process IOSurface, create the backing store at that
moment and send it to GPUP. For cases that cannot map the backing store,
i.e. GPUP IOSurface, fetch the handle through explicit synchronous call
for PlaceholderRenderingContext and view transitions. These will be
removed in future, to be superseeded with corresponding NativeImage
infrastructure.
Remove ImageBufferBackendProperties, this was only needed due to the
complications above.
