SurfaceFlinger crash is observed during simulation of
Secondary display
Note: change 14e8b01a76
removed the initialization leading to the crash when
simulating secondary display. Restore the initialization
to solve the problem.

Continuing to send the last-rendered framebuffer to HWC on subsequent
frames allows the HWC to read partially-composed regions that haven't
changed, instead of re-composing from scratch.

We were already making sure the HWComposer class had the handle before
prepare, but it wasn't passing the handle along to HWC as intended.

If the virtual display surface is being consumed by the CPU, it can't
be allowed with HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED since there is
no way for the CPU consumer to find out what format gralloc chose. So
for CPU-consumer surfaces, just use the BufferQueue's default format,
which can be set by the consumer.
A better but more invasive change would be to let the consumer require
a certain format (or set of formats?), and disallow the producer from
requesting a different format.

This change fixes a bug that caused an extra frame of latency when enabling
vsync event callbacks in DispSync. The bug was related to the logic that
prevents the two events from firing with very little time between them due to
updates to the vsync model.

When this boardconfig is defined, even when all virtual display
composition is done by GLES, the HWC will be forced to copy from the
GLES framebuffer to the output buffer. On some hardware this allows
HWC to do format conversions that would otherwise have to be done by
the consumer, with worse power and/or performance.

When GLES isn't writing to the output buffer directly, request an
implementation-defined format with minimal usage flags, leaving the
format choice up to gralloc. On some hardware this allows HWC to do
format conversions during composition that would otherwise need to be
done (with worse power and/or performance) by the consumer.

This change allows SurfaceFlinger to run at a different vsync phase offset from
that used by external listeners.

This change adds a new thread for calling HWComposer's eventControl
asynchronously. The DispSync-based vsync approach ends up enabling and
disabling HWComposer's vsync callbacks at arbitrary times, and some HWComposer
implementations do not have these calls optimized.

This change removes the wakeup latency compensation from the software-generated
vsync events. Choreographer can't handle timestamps in the future, so don't
aim for early wake-ups with the expectation that the actual wake-up will be
late.
Bug: 11153576
The screen capture code wasn't waiting for the render to finish,
so sometimes you'd see an empty or partial image.
Bug 11131777
Change-Id: Ic64087322ce3bb15bb5f4fb1eb07579880fe6197
This change adds the DispSync class, which models the hardware vsync event
times to allow vsync event callbacks to be done at an arbitrary phase offset
from the hardware vsync. This can be used to reduce the minimum latency from
Choreographer wake-up to on-screen image presentation.

In GLES-only mode, we don't have the outbuf acquire fence until after
GLES composition is done for the frame. We were setting the fence in
HWC's state immediately after dequeueing the buffer from the consumer,
before GLES had started. This fence got passed through HWC and on to
the consumer, so the consumer was reading the buffer before GLES was
done writing to it.
Now we update HWC's state just before set(), when we know we have the
right fence.

When there are no window layers for a display, SurfaceFlinger clears
the undefined region using GLES. Some of the places that check for
GLES composition weren't considering this special case, in particular:
- We were skipping the eglSwapBuffers() on these frames.
- We were putting VirtualDisplaySurface in HWC-only composition mode.
This change centralizes the logic for this special case.

Change-Id: Ia8cc084c02a0e3de910def024da8a08d02bbd89d
(a) There is no invalid EGLConfig value, in particular zero is valid.
Checking return values of eglGetConfigs and eglChooseConfig is the
only way to determine success.
(b) The "simple" EGLConfig query used as the emulator fallback should
not include EGL_RECORDABLE; the emulator doesn't have it.
