8b33f03232 update SF binder protocol to support setting display attributes
no change of functionality -- the old behavior is implemented
on top of this new protocol.
this new protocol will allow, eventually, to pass informations
about displays and layer stacks.

3094df359d First prototype atttempting to support an external display
both API and implementation will change, this is just a prototype
intended to show feasability.

SurfaceFlinger is passed an ISurfaceTexture through a new
callback, it is in turn used to create an EGLSurface which
surfaceflinger will draw into in addition to the main screen.

f785754009 Pass fences from BufferQueue to SurfaceTextureClient
ISurfaceTexture::dequeueBuffer now returns the buffer's fence for the
client to wait on. For BufferQueue, this means passing it through
Binder so it can be returned to the SurfaceTextureClient. Now
SurfaceTextureClient is responsible for waiting on the fence in
dequeueBuffer instead of BufferQueue: one step closer to the goal.

ef19414bd8 Transfer HWC release fences to BufferQueue
After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.

In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.

The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

Instead, PowerManagerService will synchronize with SurfaceFlinger to

e41b318bc4 Add a BufferQueue CPU consumer.
Aimed for use cases where gralloc buffers need to be consumed by CPU
users, such as camera image data streams.

The CpuConsumer is a synchronous queue, which exposes raw pointers to
the underlying graphics buffers to applications. Multiple buffers may
be acquired at once, up to the limit set at time of construction.

542af12d10 Fix log spam about CPU frequency on one device
Previous kernels have allowed opening the CPU frequency file regardless
whether the CPU is up or not.  This fixes some log spam on one device
with dynamic hot plug CPU feature, which does not allow opening the CPU
frequency file if CPU is down.

Also, since the file descriptors are global and have long lives, add
the close-on-exec flag.

anyone can register a callback to be executed when this happens.

Use this to reload the trace property.

a26e1cfbbc Scheduling group cleanup
Remove C++ APIs androidSetThreadSchedulingGroup and
androidGetThreadSchedulingGroup, and the ANDROID_TGROUP_* constants.

Former callers of these should now use the C APIs set_sched_policy and
get_sched_policy, and the SP_* constants.

Note: debug.sys.noschedgroups is not supported by the C APIs,
this needs to be discussed.

fa5b40ebb8 libgui: add BQ consumer buffer free notifications
This change adds a new callback for BufferQueue consumers to be notified
when the BufferQueue frees some or all of its buffers.  This is needed
to retain SurfaceTexture behavior where all buffers would be freed when
the producer disconnects.  This change also modifies the
SurfaceTextureGLToGLTest.EglDestroySurfaceUnrefsBuffers test to catch
when the buffers are not freed.

The implementation is a little complicated because it needs to avoid
circular sp<> references across what will be a binder interface (so wp<>
can't be used directly).  It also needs to avoid the possibility of
locking the BufferQueue and consumer (e.g. SurfaceTexture) mutexes in
the wrong order.

This change also includes a few additional fixes and test cleanups.

a18829ab23 Accurately track the sequence numbers of batched events.
Instead of sending finished signals immediately when appending to
a batch, record the chain of sequence numbers that were part of
the batch and then send finished signals all at once when done.
This change helps the dispatcher keep track of the true state
of the application and can improve ANR detection slightly.

This is part of a series of changes to improve input system pipelining.

f0490c94d0 Implement batching of input events on the consumer side.
To support this feature, the input dispatcher now allows input
events to be acknowledged out-of-order.  As a result, the
consumer can choose to defer handling an input event from one
device (because it is building a big batch) while continuing
to handle input events from other devices.

The InputEventReceiver now sends a notification when a batch
is pending.  The ViewRoot handles this notification by scheduling
a draw on the next sync.  When the draw happens, the InputEventReceiver
is instructed to consume all pending batched input events, the
input event queue is fully processed (as much as possible),
and then the ViewRoot performs traversals as usual.

With these changes in place, the input dispatch latency is
consistently less than one frame as long as the application itself
isn't stalled.  Input events are delivered to the application
as soon as possible and are handled as soon as possible.  In practice,
it is no longer possible for an application to build up a huge
backlog of touch events.

This is part of a series of changes to improve input system pipelining.

use a socket of type SOCK_SEQPACKET.

a94f129a7b Some hardening of isolated processes by restricting access to services.
Services now must explicitly opt in to being accessed by isolated
processes.  Currently only the activity manager and surface flinger
allow this.  Activity manager is needed so that we can actually
bring up the process; SurfaceFlinger is needed to be able to get the
display information for creating the Configuration.  The SurfaceFlinger
should be safe because the app doesn't have access to the window
manager so can't actually get a surface to do anything with.

The activity manager now protects most of its entry points against
isolated processes.

- add the ability to set the vsync delivery rate, when the rate is
set to N>1 (ie: receive every N vsync), SF process' is woken up for
all of vsync, but clients only see the every N events.

- add the concept of one-shot vsync events, with a call-back
to request the next one. currently the call-back is a binder IPC.

Added support for some of the HID application launch usages to

"Search + X" type key combos.  The goal is to encourage them

66fbde3050 Add a basic hashtable data structure, with tests!
The basic hashtable is intended to be used to support a variety
of different datastructures such as map, set, multimap,
multiset, linkedmap, generationcache, etc.

Consequently its interface is fairly primitive.

The basic hashtable supports copy-on-write style functionality
using SharedBuffer.

The change introduces a simple generic function in TypeHelpers for
specifying hash functions.  The idea is to add template
specializations of hash_type<T> next to the relevant data structures
such as String8, String16, sp<T>, etc.

a36bcd53ac attempt to fix bug 5313580
the working theory here is that a Surface object has become non-promotable
because it lost its last reference; later Surface::readFromParcel is called
the previous surface is found in the cache, but can't be promoted. this causes
a new Surface object to be created which will promptly try to connect to the
CPU_API -- this in turn will fail because the previous (now dead) surface is
still connected.

To fix this, we make sure to disconnect from the SurfaceTexture when
Surface[TextureClient] is destroyed.

a929748ddb SurfaceTexture: Fix to return the oldest of free buffers to Client on Dequeue call
Surface Texture dequeue logic is modified to return the oldest of the
free buffers to Client on dequeue call.

Currently dequeue method is returning the first buffer index which is free.
The parsing is done in ascending order of the buffer slot indices.
This leads to returning the buffer which has been just queued to composer,
and hence display, and this defeats the purpose of having minimum dequeue count
as 2 in asynchrnouse mode.

This is fixed by checking all the free slots and returning the oldest buffer.

Was mistakenly assuming that Parcel::writeFileDescriptor took
ownership of the fd that was passed in.  It does not!
Added some comments and a default parameter to allow the caller
to specify whether it wishes the Parcel to take ownership.

93ca6fb91c BlobCache: remove the mutex locking
This change removes the mutex from the BlobCache class.  The caller must
be responsible for thread synchronization in order to properly implement
the Flattenable interface, which is coming soon.  Otherwise would be the
potential for the cache contents to change between the call to the
getFlattenedSize and flatten methods.  Because the caller must do this
synchronization anyway there's no reason to also some synchronization
inside BlobCache.

3e2fb7056a Deprecate local-only CursorWindows.
There is no difference and has never really been a difference
between local-only and remotable CursorWindows.  By removing the
distinction officially in the API, we will make it easier to
implement CrossProcessCursor correctly.  CrossProcessCursor
is problematic currently because it's not clear whether a call
to getWindow() will return a local-only window or a remotable window.
As a result, the bulk cursor adaptor has special case handling
for AbstractWindowedCursors vs. ordinary CrossProcessCursors
so that it can set a remotable window before the cursor fills it.
All these problems go away if we just forget about local-only
windows being special in any way.

ec4e0063a1 Use ashmem for CursorWindows.
Bug: 5332296

The memory dealer introduces additional delays for reclaiming
the memory owned by CursorWindows because the Binder object must
be finalized.  Using ashmem instead gives CursorWindow more
direct control over the lifetime of the shared memory region.

The provider now allocates the CursorWindows and returns them
to clients with a read-only protection bit set on the ashmem
region.

Improved the encapsulation of CursorWindow.  Callers shouldn't
need to care about details like how string fields are allocated.

Removed the compile-time configuration of string and numeric
storage modes to remove some dead weight.

21230c6410 Handle orientation changes more systematically.
Bug: 4981385

Simplify the orientation changing code path in the
WindowManager.  Instead of the policy calling setRotation()
when the sensor determined orientation changes, it calls
updateRotation(), which figures everything out.  For the most
part, the rotation actually passed to setRotation() was
more or less ignored and just added confusion, particularly
when handling deferred orientation changes.

Ensure that 180 degree rotations are disallowed even when
the application specifies SCREEN_ORIENTATION_SENSOR_*.
These rotations are only enabled when docked upside-down for
some reason or when the application specifies
SCREEN_ORIENTATION_FULL_SENSOR.

Ensure that special modes like HDMI connected, lid switch,
dock and rotation lock all cause the sensor to be ignored
even when the application asks for sensor-based orientation
changes.  The sensor is not relevant in these modes because
some external factor (or the user) is determining the
preferred rotation.

Currently, applications can still override the preferred
rotation even when there are special modes in play that
might say otherwise.  We could tweak this so that some
special modes trump application choices completely
(resulting in a letter-boxed application, perhaps).
I tested this sort of tweak (not included in the patch)
and it seems to work fine, including transitions between
applications with varying orientation.

Delete dead code related to animFlags.

Handle pausing/resuming orientation changes more precisely.
Ensure that a deferred orientation change is performed when
a drag completes, even if endDragLw() is not called because the
drag was aborted before the drop happened.  We pause
the orientation change in register() and resume in unregister()
because those methods appear to always be called as needed.

73aaf0d8d2 Velocity Tracker II: The Revenge of Velocity Tracker
Bug: 5265529

Rewrote the velocity tracker to fit a polynomial curve
to pointer movements using least squares linear regression.
The velocity is simply the first derivative of this polynomial.

Clients can also obtain an Estimator that describes the
complete terms of the estimating polynomial including
the coefficient of determination which provides a measure
of the quality of the fit (confidence).

Enhanced PointerLocation to display the movement curve predicted
by the estimator in addition to the velocity vector.

By default, the algorithm computes a 2nd degree (quadratic)
polynomial based on a 100ms recent history horizon.
