6b9454d1fee0347711af1746642aa7820b1ea04d 08-Nov-2014 Dan Stoza <stoza@google.com> SurfaceFlinger: Do less work when using PTS

Currently, SurfaceFlinger is very dumb about how it handles buffer
updates at less than 60fps. If there is a new frame pending, but its
timestamp says not to present it until later SurfaceFlinger will wake
up every vsync until it is time to present it. Even worse, if
SurfaceFlinger has woken up but nothing has changed, it still goes
through the entire composition process.

This change (mostly) fixes that inefficiency. SurfaceFlinger will
still wake up every refresh period while there is a new frame
pending, but if there is no work to do, it will almost immediately go
back to sleep.

Passes the BufferItem for the queued buffer to the onFrameAvailable
callback so the consumer can track the BufferQueue's contents. Also
adds an onFrameReplaced callback, which is necessary if the consumer
wants to do anything more than simple queue length tracking.

We normally recompute layer visibility when a layer gets its first
buffer; before then it's treated as invisible. Sideband layers never
get a buffer (as far as SurfaceFlinger knows), so never became
visible. Now we also recompute visibility when a layer gets a new
sideband stream.

Sideband streams are essentially a device-specific buffer queue that
bypasses the BufferQueue system. They can be used for situations with
hard real-time requirements like high-quality TV and video playback
with A/V sync. A handle to the stream is provided by the source HAL,
and attached to a BufferQueue. The sink HAL can read buffers via the
stream handle rather than acquiring individual buffers from the

this is the first step of a series of improvements to
BufferQueue. A few things happen in this change:

- setSynchronousMode() goes away as well as the SynchronousModeAllowed flag
- BufferQueue now defaults to (what used to be) synchronous mode
- a new "controlled by app" flag is passed when creating consumers and producers
those flags are used to put the BufferQueue in a mode where it
will never block if both flags are set. This is achieved by:
- returning an error from dequeueBuffer() if it would block
- making sure a buffer is always available by replacing
the previous buffer with the new one in queueBuffer()
(note: this is similar to what asynchrnous mode used to be)

Note: in this change EGL's swap-interval 0 is broken; this will be
fixed in another change.

When acquiring a buffer, SurfaceFlinger now computes the expected
presentation time and passes it to the BufferQueue acquireBuffer()
method. If it's not yet time to display the buffer, acquireBuffer()
returns PRESENT_LATER instead of a buffer.

The current implementation of the expected-present-time computation
uses approximations and guesswork.

6b44267a3beb457e220cad0666c039d3a765cdb2 10-Jul-2013 Mathias Agopian <mathias@google.com> fix SF buffer cropping

When a buffer had a crop (meaning its content is scaled to the window size)
and a window crop was defined, the resulting crop couldn't be expressed
properly because h/w composer's API was limited to integers, since
this is fixed in h/w composer 1.3, we take adventage of this to
make sure we get the correct crop.

this bug could result in the buffer being scaled by an incorrect ratio and
be slightly offset; moreover, it would produce different results from the
GL code path, which is always correct.

since the transparent region hint really depends on the

This should help fixing drawing artifacts when changing the

* commit 'a7da0dda39cf1e807eea1304b48d4583e7329b72':
make transform hint multi-display aware
8430095879d2fa6878e68f8f12da4e704815ac09 22-Nov-2012 Mathias Agopian <mathias@google.com> make transform hint multi-display aware

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.

its own wait on the fence.

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.

HWComposer must abstract the HWC HAL entirely, so that the

0cd545f14261d829513e0d6e8fa5e4e4f3372b3d 07-Jun-2012 Mathias Agopian <mathias@google.com> sometimes we would incorrectly scale the content of a surface

this would happen when a resize was pending (ie: we have received
and processed a resize transaction but have not received a buffer
with the right size) and a new transaction came in that didn't
involve a resize, for instance a translate-only transaction.

in this case, we would incorrectly update the drawing state
with the pending size, eventhough we still don't have a buffer
for it.

the solution is quite simple, we never allow the size to propagate
from current to drawing state during the regular transaction processing
(unless we are in fixed-size mode -- meaning we don't need to have
a matching size buffer), this propagation happens later once we
receive the buffer.

This change adds a crop rectangle specified in window coordinates to the layer
state. The all window pixels outside this crop rectangle are treated as though
they were fully transparent. This change also adds the plumbing necessary for
WindowManager to set that crop.

This change makes a change in the crop, scaling mode, transform, or buffer
dimensions trigger a recomputation of the visible regions of a window. With
the new cropping behavior for SCALING_MODE_FREEZE all of these can now affect
the visible region.

This change adss support for applying a buffer crop to layers with the

rather treat all pixels outside the crop rectangle as fully transparent.

dumpsys SurfaceFlinger --latency window-name

to print the latency stats of the specified window

The data consists of one line containing global stats, followed by
128 lines of tab separated timestamps in nanosecond.

The first line currently contains the refresh period in nanosecond.
Each 128 following line contains 3 timestamps, of respectively
the app draw time, the vsync timestamp just prior the call to set and
the timestamp of the call to set.

before any buffers were available, causing the window to be treated as

the opacity determined by the buffer's format were 'opaque', a
recomputation of the opacity would not be done, and the window would
continue to be treated as non-opaque. SurfaceFlinger could then
unnecessarily draw fully occluded layers.

3d8063b02e06020c8062addcc9ec49048d3bdb9a 27-Jun-2011 Jamie Gennis <jgennis@google.com> SurfaceTexture: change onFrameAvailable behavior

This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class. The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer. This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed. Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.

The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves. This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.

even when an application died.

with this change, SF is able to do its own cleanup without

Generally we never want to lock a buffer for write access if it is at
the "head" on the surfaceflinger side. The only exception (1) is when
the buffer is not currently in use AND there is at least one queued
buffer -- in which case, SurfaceFlinger will never use said buffer
anymore, because on the next composition around, it will be able to
retire the first queued buffer.

The logic above relies on SurfaceFlinger always retiring
and locking a buffer before composition -- unfortunately this
didn't happen during a screenshot.

This could leave us in a situation where a buffer is locked by the
application for write, and used by SurfaceFlinger for texturing,
causing a hang.

Here, we fix this issue by never assuming the exception (1), it was
intended as an optimization allowing ANativeWindow::lockBuffer() to
return sooner and was justified when most of SF composition was
done in software. The actual buffer locking is now ensured by
gralloc. We could have handled screenshots in a similar way to
a regular composition, but it could have caused glitches on screen,
essentially, taking a screenshot could cause to skip a frame.

now that we removed the notion of a "inUse" buffer in surfaceflinger
a lot of code can be simplified / removed.

noteworthy, the whole concept of "unlockClient" wrt. "compositionComplete"
is also gone.

mFixedSize was never set, this bug was introduced during some "cleanup", in
practice this could cause some issues when a fixed-size buffer was used and
the window was resized.

Layer::drawForSreenShot() had a typo that had no effect.

mFixedSize was used to determine if filtering was needed, which was a bit too
conservative and created a dependency between filtering and "fixed size" states
which should exist.

Now we enable filtering based on the size of the buffer vs. the size of the layer.

Bug #3081600

The OpenGL renderer in libhwui uses a single EGL context per process and
thus create it with an RGBA 8888 EGL configuration. To ensure that all
windows are compatible with this configuration, this change modifies
the window manager and SurfaceFlinger.

The window manager now checks the window's flags and if the window is
hardware accelerated, it forces the window's pixel format to be
translucent when creating the surface. The window itself is still
marked as opaque if we know that the window will be opaque on screen.
This keeps existing optimizations in place.

Similarly in SurfaceFlinger, a translucent Surface can now be created
with the Surface.OPAQUE flag, indicating SurfaceFlinger that the surface
does not require blending, despite its RGBA 8888 configuration.

208cb0772429b9ac800010829ecc7b854bdc2d24 28-Jul-2010 Mathias Agopian <mathias@google.com> fix [2873058] Surface::dequeueBuffer blocks on last buffer, i.e. cannot dequeue all allocated buffers at once.

this situation happened when the last buffer needed to be resized
(or allocated, the first time). the assumption was that the buffer
was in use by SF itself as the current buffer (obviously, this
assumption made no sense when the buffer had never been allocated, btw).

the system would wait until some other buffer became the "front" buffer.

we fix this problem by entirely removing the requirement that the
buffer being resized cannot be the front buffer. instead, we just
allocate a new buffer and replace the front buffer by the new one.

the downside is that this uses more memory (an extra buffer) for a
brief amount of time while the old buffer is being reallocated and
before it has actually been replaced.
