* GpuProcessHost and GpuChannel do not assert if they receive an IPC message ↵apatrick@chromium.org2010-09-161-3/+6
| | | | | | | | | | | | | | that cannot be routed. Comment added to code: The object to which the message is addressed might have been destroyed. This is expected, for example an asynchronous SwapBuffers notification to a command buffer proxy that has since been destroyed. This function fails silently in that case.

* Added GPU stat for whether a GPU can report context lost.apatrick@chromium.org2010-09-071-0/+8
| | | | | | | | | | | | | | | On Windows it checks to see if the IDirect3D9 object supports Vista and later features (meaning it won't routinely report lost contexts). On Linux and Mac we can just check if its EGL versus some other GL that doesn't report lost contexts. I routed the stats to the renderer process so webkit code can query whether lost contexts are likely. I didn't wire up breakpad yet.

* Initial port of accelerated compositor to Mac OS X 10.6. Reusedkbr@google.com2010-08-041-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | infrastructure added for Pepper 3D and Core Animation plugins to render the compositor's output. The implementation allocates a fake "plugin window handle" on the browser side which is the "root" handle, containing the compositor's output, and which, if present, is drawn before any other accelerated plugin instances. Added messages from GPU process to browser process for handling window resizing and presentation of output. Added support to GGL for "view" contexts on Mac OS X, used only for the accelerated compositor, and requiring explicit resize notifications. The remainder of this port will go into the WebKit repository under https://bugs.webkit.org/show_bug.cgi?id=43398 after this for dependency reasons. Tested manually with CSS 3D and WebGL demos. Several stability and correctness issues remain and will be addressed in following CLs; however, the current code works for the majority of basic use cases including switching between accelerated compositing on and off, and scrolling of content.

This is safe because any IPC messages that are send are just queued up in the named pipe.

* Split GpuProcessHost into GpuProcessHostUIShim, which runs on the UIkbr@google.com2010-03-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | thread, and GpuProcessHost, which now runs on the IO thread and derives from ChildProcessHost. This split was necessary in order to service synchronous messages from the renderer process. Moved message handlers for GPU messages from renderer to browser from BrowserRenderProcessHost to ResourceMessageFilter. Stopped sending multiple ViewHostMsg_EstablishGpuChannel messages from the same renderer if the connection was already established. Resetting the channel was causing failures in Send, and every other page reload containing WebGL content to fail. This cleanup will allow further simplification in the GPU process, but this is being left for a subsequent CL. Fixed bug in sandboxing of GPU process. Fixed latent bugs in cleanup code in GpuChannel and GpuChannelHost. Fixed crashes in ChildProcessHost if resource_dispatcher_host_ was NULL. Fixed apparent latent race conditions in creation of BackingStoreProxy and VideoLayerProxy. With these changes, WebGL content is running in the sandbox on both Mac and Windows. Linux support will be added in a following CL.

* Calling OpenGL from the renderer processapatrick@chromium.org2010-03-251-2/+32
| | | | | | | | | | | | | | - Added ability for renderer processes to render to a real window (Windows only so far). - Added ability to create offscreen frame buffer objects that can be resized later. - OpenGL context can have a "parent" context that can access its last swapped back buffer through a texture ID. - Moved code to establish GPU channel from RenderWidget to RenderThread. - Changed way service size command buffer object lifetimes are managed.
