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.

directly into an IGraphicBufferProducer

9d4e3d2f42e93e2d12bacabe97d307d30c3c20dd 25-Aug-2012 Jeff Brown <jeffbrown@google.com> Banish DisplayID from the SurfaceFlinger API.

Use only display tokens in the API to refer to new displays.

Don't require the caller to specify the display when creating
a surface (since in general a surface could be shown on
any display).

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).
