2c9b11f0291210c9b9513a1a0cce6afebd361b3b 25-May-2014 Prashant Malani <pmalani@google.com> surfaceflinger: Replace blank/unblank with setPowerMode

We replace the blank/unblank calls in surfaceFlinger with a more generic
setPowerMode() routine.

Some displays support different power modes (for example, with reduced
color palettes). Depending on the use case we should be able to toggle
these modes, so as to achieve incremental power savings.

Initially, three power modes will be supported:

HWC_POWER_MODE_OFF will correspond to blanking the display, while
HWC_POWER_MODE_NORMAL will correspond to unblanking. HWC_POWER_MODE_DOZE
will put the display into a low power setting, if it is supported in

If such a low power mode is not supported, it should be treated as a
call to set the mode to HWC_POWER_MODE_NORMAL.

As a consequence of adding the mPowerMode field, the mScreenAcquired is
no longer required, and thus references to it are removed and replaced
equivalent references to mPowerMode.

We also add the glue code to connect the services invocation of setting
a power mode and the HAL implementation in HWComposer.

abe815dd6978b718c04f6e22e1a893d2b51d11a1 20-Mar-2013 Mathias Agopian <mathias@google.com> 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.

ISurface was only used to get the IGraphicBufferProducer from
a Layer. It's now replaced by a BBinder subclass / IBinder and
is only used as a handle to the surface, to both refer to it
and manage its life-time.

Also cleaned-up a bit the ISurfaceComposer interface and
"create layer" code path.

wrapper around Layer

f3f7db6346323ca3ec4ec449a2622adddc6306b4 31-Aug-2012 Jeff Brown <jeffbrown@google.com> Allow global transactions to nest.

This change fixes a number of small glitches that can occur when
multiple components in the same process are updating surfaces.
One would expect that updates to disjoint sets of surfaces would
not collide but this is not the case. The first component to
close the global transaction causes all pending updates to
be applied, including those that another component might not
have finished setting up if it also had an open transaction
at the same time.

6652b3edcb7ef5402c05db12f477ceb23c27d6ec 07-Sep-2012 Andy McFadden <fadden@android.com> Watch for SurfaceFlinger death

The ComposerService object wasn't watching for SurfaceFlinger
restarts, which doesn't usually matter because the app framework
restarts when SurfaceFlinger dies. However, mediaserver continues
to run, which means its ComposerService object was trying to use
a dead handle, and playback of DRM movies was failing.

This adds a DeathRecipient listener and some logic to re-establish
the SurfaceFlinger connection.

Don't require the caller to specify the display when creating

This is intended to be a minimum change just to update the API.
Note that SurfaceFlinger still uses DisplayID in a few places
internally that might cause some features not to work properly
when there are multiple displays (LayerScreenshot, for example).
