EGL now picks the buffer format out of a small set
of formats compatible with CPU consumers instead of
using the EGL_NATIVE_VISUAL_ID.

If the implementation eglCreateContext failed, we called
eglGetError(), so we could check that it set the EGL error properly.
But since we'd already called this, when the app called eglGetError()
it would get EGL_SUCCESS!

We've had the extended behavior since Android 4.3, but the extension
hadn't been ratified by Khronos yet so we couldn't add it to the

If there are two or more buffers pending that are ready for
immediate presentation, drop all but the last one.
Any code that didn't explicitly specify timestamps for buffers
was using the default value (auto-generated "now"). As a result,
surfaceflinger would drop frames whenever more than one buffer
was queued. We now use zero as the auto-generated timestamp,
and we don't set the timestamp in eglBeginFrame().

Fallout from the Flattenable change, update all its uses.
Additionnaly, fix/tighten size checks when (un)flatten()ing
things.
Removed the assumption by some flattenables (e.g.: Fence)
that the size passed to them would be exact (it can
and will be larger in some cases)
The code in Parcel is a bit complicated so that we don't
have to expose the full implementation (and also to
keep the code smallish).

this change also gets rid of the "use slow tls" option,

destroyed but current-to-a-thread resources are only destroyed
when they're made not-current; however, we were not destroying
those when the thread itself terminated, causing these resources
to be leaked forever.
we now install a tls-key destructor that takes care of this
by calling eglReleaseThread upon thread termination.

the code intended to filter out the software-renderer, but the
test as written was essentially a no-op.
the problem didn't happen most of the time because we had
updated egl.cfg to not even list the software renderer.
the test as written didn't generate a compile-time error
because String8 has a const char* cast operator; but the
end result was to compare pointers instead of the string
itself.

We now detect at runtime which sync features to use, which
allows us to remove a lot of the compile-time configuration
options. There is still one option though, to disable
KHR_fence_sync on some devices (which are more efficient
without it).
- added a backdoor to get the vendor's EGL strings
the new logic is:
- use always ANDROID_native_fence_sync if available
- fallback to KHR_fence_sync if available and not disabled
by the compile-time option
- use KHR_wait_sync if available and either of the above is
enabled

Add ES3 support to libGLESv2 and tracing tools
Import OpenGL ES 3.0 headers from Khronos SVN
Since ES3 is backwards compatible with ES2, a new wrapper isn't

Currently, to activate OpenGL tracing, an application has to be
start with --opengl-trace option (or have a debug prop set).
This CL adds support for tracing an application which may already
be running. This is implemented as follows:
- DDMS initiates a JDWP message to the VM indicating that
opengl traces be enabled.
- When that message is received, a flag is set that indicates
that tracing should be enabled.
- The trace flag is checked during every eglSwap() operation,
and if it finds that tracing should be active and it isn't,
then it starts the tracing component.

The shell property debug.egl.trace can now be set to:

The debugging and tracing levels are initialized both during
early_egl_init and egl_display_t::initialize(). For apps this has
no effect since early_egl_init is called in the context of zygote.

Hibernating EGL takes a long time (>100 ms) and blocks all other
rendering. During window animations, the outgoing activity begins
hibernation before the animation stops, causing visible stutter.
Hibernation is still available by setting 'BOARD_ALLOW_EGL_HIBERNATION
:= true' in the devices BoardConfig.mk

When eglTerminate() is called with a window surface still exists, a
deadlock would occur since egl_display_t::terminate() holds a lock
while destroying the window surface, which calls
onWindowSurfaceDestroyed() which attempts to take the same lock.
This change refactors the hibernation code and data into a separate
object with its own lock, separate from the egl_display_t lock. This
avoids the deadlock and better encapsulates the hibernation logic.
The change also fixes a bug discovered incidentally while debugging:
hibernating after calling eglTerminate() succeeds, but will cause
awakens from subsequent eglInitialize() to fail. We will no longer
hibernate a terminated display.

If the EGL implementation supports the EGL_IMG_hibernate_process
extension, use it to hibernate (and hopefully release memory or other
resources) when the process isn't actively using EGL or OpenGL ES. The
idleness heuristic used in this change is:
(a) Wake up when entering any EGL API call, and remain awake for the
duration of the call.
(b) Do not hibernate when any window surface exists; this means the
application is very likely in the foreground.
(c) Do not hibernate while any context is made current to a thread.
The app may be using a client API without the EGL layer knowing,
so it is not safe to hibernate.
(d) Only check these conditions and attempt to hibernate after a
window surface is destroyed or a thread's context is detached. By
not attempting to hibernate at the end of every EGL call, we avoid
some transient wakeups/hibernate cycles when the app is mostly idle,
or is starting to become active but hasn't created its window
surface yet.
On a Galaxy Nexus, hibernating frees 1567 VM pages from the process.
Both hibernating and waking can take anywhere from 30ms to over 100ms
-- measurements have been very inconsistent.

This is in preparation for a change that will hibernate the underlying
EGL when idle. Instead of a bare egl_display_t*, get_display() now
returns a egl_display_ptr, which acts like a smart pointer. The
"wakecount" counter managed by the smart pointer isn't used for
anything in this change. It will be used to make sure we don't
hibernate when any thread is in an EGL call, without having to hold a
mutex for the duration of the call.

from now on, the system can only have one EGL

cannot be used at the same time on a device. Of course, the

Change-Id: Id17fe4fd76eecf5f962cefb9aa32be41fc1b042d
it would happen when a context was made non-current, in this
case we would call the implementation's eglMakeCurrent() which
would succeed, if we're rescheduled at that point, another
eglMakeCurrent() could make that context current to another thread,
however, when we came back to the original call we would
overwrite egl_context_t internal state.
this is fixed by moving the critical section under
egl_display_t's lock.

This patch adds two improvements:
1. Protobuf messages are buffered and sent in chunks.
2. Multiple EGL contexts are handled properly: Corresponding
to each EGLContext, a GLTraceContext with a unique ID is created.
On eglMakeCurrent, the appropriate GLTraceContext is set and is
used while tracing subsequent GL Calls in that thread.
