Reduce sleep time in AudioFlinger mixer thread when no data has been written to output to speed up startup time when exiting standby.
The rest of the modifications for this issues is in kernel driver:
commit 0dbb0ee136ed8de757df1ae26d84556c1751deae for buffer size modification from 8192 to 4800 bytes.
Another kernel improvement that is not submitted yes will reduce delay when audio output is exiting standby.
* changes:
Add a privateImeOption to represent that the IME should not show the voice input microphone, if it otherwise would, whenever the search dialog is planning on showing a voice search button (as specified by the current searchable).
add a way to convert a mapped "pushbuffer" buffer to a gralloc handle
which then can be safely used by surfaceflinger, without including
gralloc_priv.h
Temporarily make a function public that doesn't need to be. When
host gcc-4.0.3 is gone from the build servers we can undo this.
(Cherry-picked from eclair-mr2.)
* changes:
Revert the changes that introduced new exception that wouldn't have occured before, applications don't seem to be able to handle them and we get crashes.
* changes:
When upgrading packages with shared user ids make sure we are eliminating the package about to be deleted or upgraded when updating permissions associated with the shared user. Include a simple null check when retrieving the permission.
* changes:
Check that the window which wants to force hide is visible before setting the flag forceHiding to true. If we do layout the surfaces again this flag gets set no matter what since the keyguard window is always present in the list of tokens and this hides the window which would have become visible since the keyguard just got dismissed. This causes unnecessary focus changes due to changes in visibility of current window.
in the case where we fade a 32-bits surface (ie: GL_MODULATE w/ a,a,a,a + blending),
we first make a copy of the background into a RGB buffer, then we blend the 32-bits
surface as usual (without the alpha component), and finally blend the copy of
the background on top with 1-a. This uses a lot of bandwidth, but no CPU time.

* changes:
Fix bug 2201417. Whenever the System setting that indicates whether the notifcation stream uses the ring volume changes, the table of stream volume aliases in AudioService is updated. But the name of the alias stored in VolumeStreamState.mVolumeIndexSettingName was not updated whenever the NOTIFICATIONS_USE_RING_VOLUME setting was updated. This caused the wrong volume setting to be persisted. This change ensures the setting name is updated whenever the volume alias is, and persists the notification volume change right away (instead of after a delay), so that registered observers are notified right away. The notification seekbar in the sound settings is an example of such an observer.
