* Turn on glsl built-in function emulation in ANGLE shader translator.zmo@google.com2011-09-201-2/+3
| | | | | | | | | | | | At the moment we need to turn it on for ATI/Mac and also Windows/D3D. Also, added the switch to turn of driver bug workaround, although this CL doesn't hook it up with all workarounds yet. BUG=96293 TEST=failing webgl glsl feature tests passing, with the switch, these tests fail.

| | | | | | | | | | | each flush.This means glFlush is a barrier that prevents reordering of GL commands issued on different command buffers. I used it to replace latches for synchronizing the rendering of WebGL canvas and Pepper 3D with the accelerated compositor. The primary advantage is it is more robust than latches and there is no possibility of deadlock. It should also be possible for WebGL and Pepper 3D to use it whereas exposing SetLatch and WaitLatch would be dangerous. The calls to SetLatch and WaitLatch are still in webkit but they are no-ops. SetLatch and WaitLatch are completely removed elsewhere.I changed CommandBuffer::FlushSync to Finish to reflect the new semantics. Going forward, I will add a synchronous CommandBuffer::WaitForToken and WaitForAvailableEntries, which should eliminate the need to call Finish unless glFinish is called by the client. The Pepper interface is unchanged because I don't want to break binary compatibility.I fixed a bug where the last read token in CmdBufferHelper was stale after receiving a ReportState IPC. That was causing a redundant synchronous flush in the client side SwapBuffers throttling. I removed Yield because it does not make sense with the new semantics. There is no round robin scheduling.Tested with WebGL on Windows and Mac and checked that 72672 did not regress.

* GpuScheduler fix:jbates@chromium.org2011-06-031-0/+14
| | | | | | | | | | | - Ganesh generates a lot of cheap GL commands, so 100 commands were executing in 50us, causing us to spin on PostTask(ProcessCommands) 60+ times per frame. This change simply tracks the elapsed time after each 100 commands - if the time is less than 2ms, it continues on to the next 100 commands. BUG=83628 TEST=trace FishIE demo with 500 fish, check that ProcessCommands is not called ~60 times per frame.

* Move lots of GMock stuff out of line.erg@google.com2011-01-051-14/+7
| | | | | | | | | | | | | | Nico did some treemapping of our build time on Mac, and (surprise!) gmock unittests dominated. Gmock works with several large, heavy templates, and previous patches that out of line the ctors/dtors have significantly sped up compilation (e.g.GLMock) and have reduced thrashing.

These entry points are needed in order to allow WebGL to both query the available extensions and enable them individually. Added these entry points to WebGraphicsContext3DCommandBufferImpl. A subsequent WebKit checkin under https://bugs.webkit.org/show_bug.cgi?id=40316 will utilize them and implement the OES_texture_float extension for WebGL.

* Removed dependencies on base from GPU common and client code.apatrick@chromium.org2010-09-081-1/+3
| | | | | | | | | | | | | The main change was to make scoped_ptr and the basic types the same for both NaCl and trusted plugins and to implement new logging code for GPU common and client code. Service code and unit tests can still use the logging code in base. I am really not happy with the new logging code but I thought I'd let you take a look at it to see what you think. The biggest thing I don't like is it uses assert(false) to throw an exception in a platform independent way, which brings up a modal dialog. Not ideal in the middle of a unit test run. I don't know if that will make the bots hang. Hopefully they'll time out or something.
