68a6afeb26 fix [2122448] android_native_window_t::setUsage() only reallocates the first buffer
Take 2. We needed to check that the usage flags are "good enough" as opposed to "the same".

This reverts commit 8f17a762fe9e9f31e4e86cb60ff2bfb6b10fdee6.

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

ba5972ffdc make sure to update a surface's usage bits when it changes, instead of only the first time.
also fixed a few locking issues in Surface and commented how each member is protected.

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.

cb6b904164 fixed some issues with the software renderer when surfaces are made current.
there was several issues:
- when a surface was made non-current, the last frame wasn't shown and the buffer could stay locked
- when a surface was made current the 2nd time, it would not dequeue a new buffer

now, queue/dequeue are done when the surface is made current.

for this to work, a new query() hook had to be added on android_native_window_t, it allows to retrieve some attributes of a window (currently only width and height).

7189c0054e move opengl/include/EGL/android_natives.h to include/ui/egl/android_natives.h and don't include it from egl.h
the android_native_ types are just forward declared in egl.h

21c59d0070 get rid of android_native_buffer_t::getHandle() and replace it with an handle field
this abstraction was not necessary. things are easier now.

e71212ba53 removed the "bits" attribute from android_native_buffer_t.
"bits" can never be trusted now that we need to call lock() on the handle to get the virtual address of the buffer.

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

18d8446fe1 cleanup, remove unused fields. Also make sure that we don't systematically allocate a Surface in Surface.java if only a SurfaceControl is needed (Common case). 2009-04-16 20:30:22 -07:00

01b766839e more splitting of Surface/SurfaceControl. Surface.java is now implemented in terms of Surface and SurfaceControl.
The WindowManager side of Surface.java holds a SurfaceControl, while the client-side holds a Surface. When the client is in the system process, Surface.java holds both (which is a problem we'll try to fix later).

62185b7335 split Surface.cpp into Surface and SurfaceControl
SurfaceControl is used for controling the geometry of the surface (for the WM), while Surface is used to access the buffers (for SF's clients).
SurfaceFlingerClient now uses the SurfaceID instead of Surface*.

Currently Surface still has the SurfaceControl API and is implemented by calling into SurfaceControl.

40b7f6e043 fix some issues with Surface's lifetime management.
To deal with Java's lack of destructors and delayed garbage collection, we used to duplicate Surface.cpp objects in some case; this caused some issues because Surface is supposed to be reference-counted and unique.
