c8c7109619 Abort surface composition if hw surface is invalid
If an invalid display device is detected during surface composition
(e.g., a simulated secondary display is removed), abort the
composition.

f3e85d4327 take the "transparent region" into account for blending
until now it was only used to discard a layer entirely.
we're now reducing the size of the layer if it is still
visible, if possible.

this works for instance when a surfaceView is used and
only the menu bar is displayed over it.

91d25932b6 DO NOT MERGE Make sure surfaces always have latest orientation info
When the screen is turned off, the current stack is set to -1. This causes
logic in iSurfaceFlinger's handleTransactionLocked() function to fail to
match the current stack, and the latest orientation is not set into the
layer. This causes BufferQueue, later, to potentially set an obsolete
transformHint on a created surface (such as in the case with ImageWallpaper's
Egl surface, in the bug below).

The fix is to note this situation and use a default value for the DisplayDevice,
which should have the current orientation information.

Issue #8508397 ImageWallpaper sometimes rendered in wrong orientation causing a ~30-40% drop in graphics performance

Mathias Agopian
9eb1f0558b fix another bug where screenshots could end-up all black
SF transactions were always handled on VSYNC which allowed
the screenshot to sneak-in between closing the transaction
and vsync (before it's latched), resulting in a screenshot
with the previous state.

we now always force transactions to happen immediately
before screenhots.

can't do that for virtual displays. The dimensions are used to set the
display frame of the framebuffer target layer passed to HWC, and
implicitly the dimensions of the virtual display.

2ca79399b9 latch transparent region hint only when we get a new frame
since the transparent region hint really depends on the
content of the window containing the SurfaceView
(it's calculated by the view hierarchy based on
overlapping views), it makes sense to latch it only when
the content of the window (the app) changes.

This should help fixing drawing artifacts when changing the
layout of a window containing a SurfaceView.

ca08833d5e don't use compile-time configuration of libgui as much as possible
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

ffe1f19ca9 Fix virtual displays for HWC<=1.1
If we're using a HWC that doesn't support virtual displays, or we have
more virtual displays than HWC supports concurrently, the
VirtualDisplaySurface should simply be a passthrough from source
(GLES) to sink.

This change also tries to distinguish between display types and HWC
display IDs a little better, though there's more to do here. Probably
needs a higher-level rethink; it's too error-prone now.

851cfe8342 Isolate knowledge that fb target == output buffer
HWComposer didn't allow the virtual display output buffer to be set
directly, instead it always used the framebuffer target buffer.
DisplayDevice was only providing the framebuffer release fence to
DisplaySurfaces after a commit.

This change fixes both of these, so both HWComposer and DisplayDevice
should continue to work if VirtualDisplaySurface changes to use
separate framebuffer and output buffers. It's also more correct since
VirtualDisplaySurface uses the correct release fence when queueing the
buffer to the sink.

abe815dd69 rework how we take screenshots for a CPU consumer
We're not using IMemoryHeap as a transport anymore,
instead we're providing a CpuConsumer and use the
IGraphicBufferProducer version of the screenshot API.

However, some GPU drivers don't support properly
a GPU to CPU path, to work around this, we use a
temporary BufferQueue on the server side for the
GL rendering, and we use glReadPixels into the
CpuConsumer (we're now using a CPU to CPU path
which is always supported).

Currently this "wrapping" is always performed,
but it can be bypassed on devices that support
the GPU to CPU path.

This also addresses a DoS attack vector on
SurfaceFlinger, where an application could
consume all of SF's filedescriptors by creating
a lot of screenshots in a row.

80e0a397a4 Add BufferQueueInterposer and use it for virtual displays
BufferQueueInterposer allows a client to tap into a
IGraphicBufferProducer-based buffer queue, and modify buffers as they
pass from producer to consumer. VirtualDisplaySurface uses this to
layer HWC composition on top of GLES composition before passing the
buffer to the virtual display consumer.

7adb0f8a9f Minor cleanups/fixes before virtual display refactoring
None of these should change behavior, except for removing some
incorrect log messages when using a virtual display.

- HWComposer::getAndResetReleaseFenceFd() checks the HWC version, so
  no need to do that in the DisplayDevice::onSwapBuffersCompleted().
  However, it should check that mFramebufferSurface is not NULL like
  it is for virtual displays.
- Comment that FramebufferSurface::dump() overrides the non-virtual
  ConsumerBase::dump(), and fix it so the right thing happens
  regardless of the static type of the pointer/reference the callee
  has. FramebufferSurface::dump() could be removed right now, but I'd
  need to bring it back in a later change.
- Use the right enum for validating display type ids.
- Don't try to send hotplug events for virtual displays.
- Mark virtual displays as connected so HWComposer::prepare() doesn't
  think something is wrong when it gets a non-NULL layer list.
- Remove unused FramebufferSurface methods.

- reimplement LayerScreenshot such that its
  BufferQueue is directly used as the destination
  of the screenshot. LayerScreenshot is now a thin

01e29054e6 Init displays to null layer stack
When a display is added, initialize it to use an empty layer stack, so
if it is somehow visible it will show black. It will be assigned the
real layer stack -- along with a projection and other properties -- by
window manager soon. Normally a display remains blanked until window
manager has decided what to show on it, but for HDMI connected at boot
that isn't currently the case.

f5f714aa18 apply the projection's viewport to the visibleregion passed to hwc

so this should be reflected in the visibleregion passed to
h/w composer.

DisplayDevice getViewport and getFrame are now guaranteed to return
valid Rects.

5219a06d61 set correct crop rectangle in LayerBase::setCrop
The crop always had left=top=0, because the crop position
and the layer's transform were merged together in
computeBounds() (which really used to compute the
bounds in screen space, which we usually call the
"frame" elsewhere in the code)

Note: in practice this crop value is not used by
hwc, because it's overridden in Layer::setGeometry(), which
is why this bug was never apparent.

if a layer is not mirrored, we now use its display
as the source for the transfrom hint calculation
instead of always using the default (main) display.

this change does two thing:
1) we make updateTransformHint take a DisplayDevice
   as a parameter instead of hard-coding the
   main display.

2) each time we do a transaction that could change
   the hint, we go through all layers and
   figure out which display should be used for their
   transform hint.

In this change we ignore the dirty region for the purpose of
rejecting the whole update and we rely on the fact that it will later
be expanded to the whole screen. This was the least risky fix.

dd3cb84cfb SurfaceFlinger: add support for secure displays
This change adds support for displays that are not allowed to display surfaces
with the eSecure flag set.  All non-virtual displays are considered secure,
while virtual displays have their secure-ness specified at creation time.

620685c2e6 Fix emulator vsync
The code that reserves display IDs was only run when a hardware
composer was present.  The eventControl() function, which handles
enabling of vsync, was ignoring the request because the primary
display didn't appear in its set of allocated IDs.  This moves
reservation of IDs for built-in displays outside the HWC-only block.

Also, added a couple of warnings in eventControl().

db9b41fd15 fix a corruption in blank/unblank
we were holding a reference (ie: pointer) to a sp<DisplayDevice>
while processing the message. Meanwhile the object itself could
go away and we would end up accessing a dead object.

the root cause of the problem is that we are accessing mDisplays[]
in a few places outside of the main thread.

2d5e230292 SurfaceFlinger: add animation transactions
This change adds a transaction flag for WindowManager to indicate that a
transaction is being used to animate windows around the screen.  SurfaceFlinger
will not allow more than one of these transactions to be outstanding at a time
to prevent the animation "frames" from being dropped.

The screenshot is a GL_RGB texture, and the GL_REPLACE texture env
mode uses vertex alpha for GL_RGB textures instead of alpha=1.0.

9e9689c111 Fix HDMI unblank behavior
Two issues:

(1) We were announcing the hotplug event before we were ready to
handle blank/unblank events, so we were losing the initial unblank
that power manager sends us when HDMI is first plugged in.  This
left the display blank until you toggled the device power off/on.

(2) We were retaining fbTargetHandle for HDMI after the display was
disconnected.  The value didn't get updated when HDMI was reconnected
because the display was blank, so we didn't go through that code
path.  So, when HDMI was re-connected, we passed stale data into
the HWC.

3292cae8c3 don't automatically unblank external displays
this should be handled by the display-manager. we were doing
that in SF because until recently we didn't have enough support
in the HAL. however, this is now causing other problems when
plugging hdmi while the screen is off for instance.
