cbb288bfe8 fix [2068105] implement queueBuffer/lockBuffer/dequeueBuffer properly
Rewrote SurfaceFlinger's buffer management from the ground-up.
The design now support an arbitrary number of buffers per surface, however the current implementation is limited to four. Currently only 2 buffers are used in practice.

The main new feature is to be able to dequeue all buffers at once (very important when there are only two). 

A client can dequeue all buffers until there are none available, it can lock all buffers except the last one that is used for composition. The client will block then, until a new buffer is enqueued.

The current implementation requires that buffers are locked in the same order they are dequeued and enqueued in the same order they are locked. Only one buffer can be locked at a time.

eg. Allowed sequence:   DQ, DQ, LOCK, Q, LOCK, Q
eg. Forbidden sequence: DQ, DQ, LOCK, LOCK, Q, Q

1c97d2ebe1 fix a bug that caused the PixelFormat viewed by Surface to be wrong.
what happened is that the efective pixel format is calculated by SF but Surface nevew had access to it directly.
in particular this caused query(FORMAT) to return the requested format instead of the effective format.

5221271375 second take, hopefully this time it doesn't break one of the builds: "SurfaceFlinger will now allocate buffers based on the usage specified by the clients. This allows to allocate the right kind of buffer automatically, without having the user to specify anything." 2009-08-11 23:32:29 -07:00

df37b62c62 SurfaceFlinger will now allocate buffers based on the usage specified by the clients. This allows to allocate the right kind of buffer automatically, without having the user to specify anything.
This change makes SurfaceHolder.setType(GPU) obsolete (it's now ignored).
Added an API to android_native_window_t to allow extending the functionality without ever breaking binary compatibility. This is used to implement the new set_usage() API. This API needs to be called by software renderers because the default is to use usage flags suitable for h/w.

f9cd64bc6c NPOT EGLimage without GL_ARB_texture_non_power_of_two would be improperly scalled
The current gralloc allocates buffer memory for render targets that will typically have NPOT dimensions. Assuming that the vendor driver supports converting the resulting NPOT android_native_buffer_t to a NPOT EGLImage, SurfaceFlinger calls glEGLImageTargetTexture2DOES(), and uses glGetError() to test whether the GL can support creating an EGL target texture with the specified NPOT EGLImage. If it is supported, the DIRECT_TEXTURE flag remains set, otherwise it is cleared.

Tangentially, if the driver advertises the GL_ARB_texture_non_power_of_two extension, the NPOT_EXTENSION flag is set, otherwise it is cleared.

If the driver supported creating an EGL target texture from a NPOT source EGLImage, it implicitly creates a NPOT texture. This does not need any glScalef() texture coordinate correction in LayerBase::drawWithOpenGL(). However, the same driver may not advertise the GL_ARB_texture_non_power_of_two extension nor generally support NPOT textures that were not derived from EGLImages. So SurfaceFlinger may flag only DIRECT_TEXTURE, not NPOT_EXTENSION.

Therefore, the test in LayerBase::drawWithOpenGL() should only perform the glScalef() if neither NPOT_EXTENSION or DIRECT_TEXTURE are flagged. Otherwise scaling is applied to NPOT EGL target textures when none is required.

0926f50664 update surfaceflinger, libui and libagl to the new gralloc api
- Currently the lock/unlock path is naive and is done for each drawing operation (glDrawElements and glDrawArrays). this should be improved eventually.
- factor all the lock/unlock code in SurfaceBuffer.
- fixed "showupdate" so it works even when we don't have preserving eglSwapBuffers().
- improved the situation with the dirty-region and fixed a problem that caused GL apps to not update.
- make use of LightRefBase() where needed, instead of duplicating its implementation
- add LightRefBase::getStrongCount()
- renamed EGLNativeWindowSurface.cpp to FramebufferNativeWindow.cpp

- disabled copybits test, since it clashes with the new gralloc api

- Camera/Video will be fixed later when we rework the overlay apis

9a11206fe7 more Surface lifetime management
Surfaces are now destroyed once all references from the clients are gone, but they go through a partial destruction as soon as the window manager requests it.
This last part is still buggy. see comments in SurfaceFlinger::destroySurface()
