Since we dump image in DrawQuad, LayerScope can not dump image correctly while HWC is chosen.

I think we should either make it work or always enable GLCompositor while there is a viewer attached.
Blocks: LayerScope
As we know, LayerScope Tool needs "GLContext" and "EffectChain".

However, after the discussion with Morris this morning, we don't need "GLContext" on the view tool now, so I will set the address to 0 by default in other compositors, such as HwcComposer2D, BasicCompositor, CompositorD3D9, and CompositorD3D11.
Sorry, I should correct my comment. All the compositors will set "GLContext" to 0 by default.
Now, I can implement a general function, GenEffectChain(), in:
  1. Image Layer
  2. Thebes Layer
  3. Color Layer
  4. Canvas Layer
to generate the correct EffectChain for LayerScope tool, and also another general function, GenEffect(), which can generate a primary effect according to the different CompositableHosts in:
  1. ImageHost, Deprecated ImageHost
  2. ContentHostBase, Deprecated ContentHostBase

BTW, according to the discussion with Morris last week, we still need GLContext for HwcComposer2D, so I am going to trying to investigate how to collect layer data (to retrieve GLContext for HwcComposer2D), handle TextureHost lock/unlock problems, and generate the correct EffectChains from the generation functions above.
Assignee: mtseng → boris.chiou
Part 1: Implement general function, GetEffectChain().

1. Add GetEffectChain() for (Image|Thebes|Color|Canvas)LayerComposite.
2. Add an auto lock mechanism for CompositibleHost. Now we can lock the
   TextureHost in ImageHost or ContentHost by the autolock.
3. For each CompositibleHost, add GenEffect() to generate the
   primary effects for each host.
Attachment #8408849 - Attachment is obsolete: true
Part 2: Support LayerScope for Hardware Composer

1. This design still uses GLContext to read texture source for HwcComposer2D.
2. Use auto begin/end frame to handle the frame stamp.

No need to be virtual

And this new class is cool
Status: NEW → ASSIGNED
Thanks for your review, CJ.
I should discuss the "else" part with Morris. 
BTW, I am trying to retrieve raw texture data from ANativeWindowBuffer (from LayerRenderState), instead of GLContext. If this method can work, I will revise the APIs in LayerScope to handle the specific Hardware Composer case.

Since you add LayerScopeAutoFrame, suggest to move these two functions out of header.

Not relative to change in this patch. But, do you know why DebugDataSender::mList need to be a pointer instead of an object? If no special reason existed, suggest change it to an object member
According to the implementation, I think we can use a LinkedList object here.

It may become lazy init one, but I think we shouldn't revise its position in the patch. If the Init() does more things in the future, I will try to change it. Thanks.
Updated:

Actually, I got some gen lock failed issues after using lock/unlock of graphicBuffer in HwcComposer.
ex. 
ContentClientDoubleBuffered::FinializeFrame()
{
  DebugOnly<bool> locked = mTextureClient->Lock(Openmode::Open_READ_WRITE);
  MOZ_ASSERT(locked);   // <-- assertion failure
}
errors:
> libgenlock: perform_lock_unlock_operation: GENLOCK_IOC_DEADLOCK failed (lockType0x1, err=Connection timed out fd=125)
> msm7627a.gralloc: gralloc_lock: genlock_lock_buffer (lockType=0x2) failed
> GraphicBufferMapper: lock(...) failed -22 (Invalid argument)
> MOZ_ASSERT: Assert: Assertion failure: locked, at /.../gecko/gfx/layers/client/ContentClient.cpp:451

Sotaro mentioned this problem in Bug 898919 Comment 44 and Bug 912134 Comment 18.

According to these comments:
When using gralloc buffers, the user of the buffers need to grab genlock. OpenGL rendering and HwCompser rendering could switch dynamically in each rendering. If HwComposer or OpenGL continue to keep gralloc buffer's genlock, another one can not get genlock and wait until got the genlock is freed. If the wait time is longer than genlock timeout, "genlock failure" log printed to logcat. I wrote this genlock owner ship competiion as "gralloc usage conflicts".

This "gralloc usage conflicts" has 2 patterns.
-(1) multiple user try to use gralloc buffers simultaneously.
-(2) genlock is not released after user.

I indeed unlock each graphic buffer after locking it, so I think it's the pattern (1). In my unagi, OpenGL and HwcComposer switch often, and I usually lock/unlock the graphic buffer in HwcComposer, so it's easy to get a gen lock failed error. In the leo, the frequency of switch between OpenGL and HwcComposer is not very high, so it's not easy to reproduce the gen lock failed. (Actually, I only got one in these two days.)
I recently update a way of gralloc buffer binding by Bug 1005908. It seem to simplify the binding problem except tiling layer.

diego, any comment or suggestion for lock fail?

Sotaro,
Thanks for your information. Actually, my gecko already had your patch. I think the root cause was the graphicBuffer lock/unlock I added in HwcComposer (for LayerScope tool), even if I did nothing between the lock() and unlock(). They may affect the read & write locks in ContentClient double buffering.

I think Boris' comment 34 is spot on. If you have any questions specific to HWC then sushilc (cc'ed) or I can try to answer them.

why not just move switch statement into SnederHelper::SendLayer?

Part 1: General functions for EffectChains

Since you add GenEffect() to all XXXXComposite class, I think you can also reuse this function to generate the effect used in CompostiorOGL::DrawQuad().

Many classes access the LayerScopeWebSocketManager in this file, so I wrapped it as a static class.

OK
1. Retrieve buffer from GPU.
2. Refactor - use SenderHelper class to manage the Sender
   static function structure.

I can reuse the GenEffectChain() for ColorLayerComposite. However, (ThebesLayer|CanvasLayer|ImageLayer)Composite needs CompositableHost and should lock it first (by autolock). If I want to reuse GenEffectChain for these layers, Changing the scope of the lock of ContentHost or ImageHost is necessary. I am unsure the impact of it, so just keep the original code in my new patch. If changing the scope doesn't affect anything, I could generate the primary effect out of the composite function.
1. Support GenEffectChain() for LayerComposite.
   Each layer can use this API to gen the
   EffectChain (only primary effect now)
2. Support GenEffect() for CompositableHost.
3. Move AutoLock to compositeHost.

Rebased.

Remove dead code or put a comment why it's disabled and when it should be enabled.

Please outdent so #if start at column 0.

OK, I will remove this dead code in my next patch. Thanks.

OK, maybe I can rebase it.

All I see in this Try run are builds. Did we verify that tests pass too?

2. Refactor - use SenderHelper class to manage the Sender
