* Flush command streams after deleting resourcesjamesr@chromium.org2011-08-053-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When share groups and pooled IDs are in use, a race condition exists when destroying resources since the IDs are marked as free before the resource is actually freed. Consider: Context A creates a framebuffer with id 1 Context B is created in the same sharegroup as A Context A destroys its framebuffer: - the ID is freed (via FreeIDs(), which is a synchronous call) - a DeleteFrameBuffersImmediate command is entered into A's command buffer but does not immediately execute Context B creates a framebuffer - genFramebuffer() makes a sync call to the service side, which reports that id 1 is available At this point, if the service side processes and commands in context B's command stream, it will throw kInvalidArguments because as far as the service side is concerned framebuffer 1 has never been released. This patch adds a Flush() after destroying a resource so that the service side will process the resource destruction command before servicing other command streams. There's still a potential race condition if multiple contexts in the same share groups are making calls from different threads, but today all contexts in the same share group are on the same thread.

* Insert a soft flush into the command buffer on unmapTexSubImage2Djamesr@chromium.org2011-07-281-0/+2
| | | | | | | | | | | | | | | | | | This does a CommandBufferHelper flush in UnmapTexSubImage2DCHROMIUM so the gpu process can start processing texture uploads as soon as the texture is unmapped instead of waiting until the next hard flush or finish. This increase parallelization for tile uploads, especially during compositor startup and when the entire root layer is damaged.

* Create new GLSurface for cross process image transport.backer@chromium.org2011-07-224-138/+24
| | | | | | | | | | | | | | | Currently cross process image transport (on OSX and TOUCH_UI) uses the WebGL code path to render to a texture via FBO. This makes a clean break with path and centralizes the GL context specific IPC communication in one location. By separating from the WebGL code, I was able to avoid wasting a texture attached to the FBO in the decoder (the old code ignored this attachment --- the new code makes no such attachment at the decoder level). As a test of the new architecture, I have also implemented XComposite/GLX_texture_from_pixmap image transport (i.e. it's now possible to use the --use-gl=desktop backend on touch_ui builds).

* Detect and expose loss of OpenGL context using GL_ARB_robustness.kbr@chromium.org2011-07-1420-64/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (This CL was originally reviewed under http://codereview.chromium.org/7331020/ . The only difference is the removal of an #include from command_buffer.h that was accidentally left in and which caused a significant increase in the number of files containing static initializers, presumably because of the dependent #include of <iostream>.) This initial patch changes the Linux port to use GLX_ARB_create_context_robustness when available, and tests periodically whether the context has been lost after each draw call and when making the context current. The detection of context loss also works with EGL and ANGLE, although it always reports an unknown reset status. WebKit changes will follow which test the reset status and determine what to do in response; for example, the policy might be to never restore a WebGL context which was lost (due to a GPU reset) and which was determined to be the guilty context. Tested manually with WebGL stress tests and verified on Linux and Windows that in at least some situations it is possible to detect guilty contexts and shut down the associated WebGL application. Some precision of this detection was recently lost and will need to be fixed in following CLs. Also updated and ran GPU unit tests.

* Cooperatively round robin GPU command buffers.apatrick@chromium.org2011-07-122-10/+24
| | | | | | | | | | | The renderer processes asynchronously flush every n milliseconds. This prevents one renderer process from starving the others by issuing excessive amounts of GL calls without flushing. Also has the advantage that the GPU process more evenly spreads its work out over the course of the frame.
