For an offloaded stream the size is always counted in bytes
(frame size == 1) and the number of channels is irrelevant.

Flush is used to quiesce a camera device as quickly as possible, which
can be used to deal with a pathological client (requests a frame
duration of hours then dying) as well as speed up stream configuration
changes when the outstanding requests data isn't required.

HALs seem to need to know the gralloc usage flags of the opposite
endpoint (producer/consumer) of a stream at configure time.
Instead of adding another call to pass stream information, we just
pass the usage flags in the existing usage field.

Add hints for video encode and decode use cases. These
hints are sent when the relevant use case starts and ends.
Clients can also send metadata along with the hint to provide
context to the power HAL so that it can make more informed
decisions about how to tweak system-level parameters.

Align camera2's management of platform-opaque formats with rest of
framework. Instead of using CAMERA2_PIXEL_FORMAT_OPAQUE, use
HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED as the format for both the
camera HAL and for gralloc, and depend on the gralloc usage flags to
let the gralloc module select the appropriate real format for specific
stream endpoints.
Add a new gralloc usage for ZSL mode, where the camera service will
hold a streaming circular buffer of opaque full-resolution images
during camera preview. Since this is an opaque format that needs to be
optimized for 30fps operation, need gralloc to be aware of this use

During the HWC 0.x evolution, some fields were left optional or
organized strangely to avoid breaking backwards compatibility. Since
we're breaking it in the transition to HWC 1.0 anyway, we can clean
these up a little.
* The current callbacks are now registered immediately after the
device is opened and guaranteed to be present, so the implementation
can rely on them being present.
* The hwc_methods_t structure is gone, with its two methods folded
into the main hwc_composer_device_1_t.
* All methods and callbacks are now required except dump(). New
methods and callbacks we add in the future will still be optional
for backwards compatibility.

disable hardware composition, though that wasn't documented. Now
we'll call prepare with non-NULL pointers but the layer list will
have zero layers.
* Set won't be called with NULL pointers. This used to cause the
display to turn off; that is now done by calling the blank() method,
which is no longer optional.

hwcomposer_defs.h now contains enums, which are essentially names.

the hwcomposer's data structures (which are a lot more fragile wrt.

The previous names and documentation were not clear as to how the
version fields should be used. As a result, they were often either
unused or used improperly.
It became clear that there were two version fields necessary. One
to version the implementing module and the other to version the
hw_module_t interface itself.
This change renames version_major and version_minor members of
hw_module_t to module_api_version and hal_api_version. It also
provides in-depth descriptions for all the fields and clarifies
the purpose of the version field in hw_device_t structure.

Refactor the local/common clock services.
This change is one of a set of 5 changes made to different repositories. Look
for this comment in all of them.
Refactor the local/common clock services to match android best
practice. Notable changes include
+ The kernel no longer knows anything about common time. Common time has been
moved completely up into user land. This has an impact on the accuracy of the
timesync debugging code, and the netfilter assisted approach to network based
timesync is going to have to be modified.
+ The timesync driver used by A@H is now just local time driver.
+ The kernel no longer needs access to the linear transform math code, and it
has been removed.
+ A new HAL has been introduced to expose the concept of local time to the
system.
+ A non-slewable stub implementation of the local time HAL based on
CLOCK_MONOTONIC has been added.
+ The old library has been eliminated. Its functionality has been
distributed among the common time binder service, the local time hal and the
linear transform utility code.
+ All clients of the old library have been changed to be clients of
the binder service, the hal and the utility code.
+ The reset_tt utilities have been removed, they no longer have a purpose in the
system.

audio effect CPU usage on enable and unregister on disable
instead of when the effect is created or destroyed.

This change adds a new Gralloc usage bit to indicate that the Gralloc
buffer being allocated will be passed to the HWComposer HAL module.

The <hardware/qemu_pipe.h> header was missing an include
that causes the code under development/tools/emulator/opengl
to fail to compile on OS X.
You need to define BUILD_EMULATOR_OPENGL=true in your
environment, otherwise this code doesn't get built yet by default.

With the new model, we will try to connect client via pipe first, and only if
the pipe connection is not available we will fall back to the socket connection.

AEC and NS via set_parameters according to BT headset capabilities.

This is useful in various situations, for instance if the HAL
wants to change its compositing strategy.

-- add a callback to camera_memory_t that can be used to free the requested
memory
-- memory requests are in the form of N buffers S bytes each
-- data callbacks pass an index to a buffer in addition to the camera_memory
pointer

Moved and renamed media/EffectApi.h to hardware/audio_effect.h
Modified the effect library API to expose a library info structure
containing an interface functions table.
Also removed enums for audio channels, audio format and devices
from effect API and use values from system/audio.h instead.

fb and gralloc are part of the same HAL for now,
but for clarity we split them into these two headers.

camera.h
-- a HAL module for the camera, camera_module_t, which can be queried for the
number and orientation of the available camera sensors. A camera sensor is
also opened through this module, and is represented by:
-- a HAL device for each camera sensor, camera_device_t, which encapsulates all
the functionality of the base class CameraHardwareInterface;

This header is used to implement qemu pipes, a very fast way to exchange
messages between the guest and the emulator program. See implementation and
tests under development/tools/emulator/system/libqemu/

Needed for things like audio and audio effects. Provides a
new interface to loading modules named 'hw_get_module_by_class'.
This takes two parameters: 'class_id' and 'instance' which are
used to construct the filename for the module to be loaded. If
instance is NULL, then this function acts identically to
hw_get_module where 'class_id' == 'id' (and in fact the latter
implemented exactly this way).
For audio, this new mechanism allows us to load multiple audio
interfaces by doing:
hw_get_module_by_class("audio", "primary", &module);
hw_get_module_by_class("audio", "a2dp", &module);
hw_get_module_by_class("audio", "usb", &module);
...
In the future we will likely want to add the ability to load a set of
module instances based on a config file, which will have a standard
syntax and the mechanism will be provided by libhardware.

the rotation-vector sensor must transmit the W component of the
unit quaternion in data[4].
This change doesn't cause a compatibility issue because nothing in the
system relies on the W component being present.

This change adds a gralloc usage flag to indicate that a buffer should
be displayed full-screen on an external display if one is present.

fix part of [Issue 3114236] [Crespo] The order of FLIP_H and ROT_90 is different from other devices
there are a typo in hardware.h where FLIP_V and FLIP_H were inverted.
this change will probably break all the overlay HALs which
implement FLIP_V/H, which thanksfully are not many.
