8ddaa824ab libcamera: pipeline: Fail match() when no camera is registered
The rkisp1 and simple pipeline handlers can fail to register any camera,
if initialization of all the detected cameras fail. In that case, they
still return success from their match function. As no camera gets
registered, the pipeline handler is immediately destroyed, releasing the
acquired media devices, and the camera manager immediately tries to
match the same pipeline handler with the same media device, causing an
endless loop.

Fix it by returning false from the match function if no camera gets
registered.

732ea045f5 cam: options: Rename optional arg to prevent shadowing
The parseValue function is given the optarg directly from the getopt
library, but the function retains the same name.

This causes an shadowed variable of the global optarg variable to be
present in the parseValue function. While this is not harmful, rename it
to work towards disabling shadowed variables.

e1f9fdb8a5 android: camera_device: Remove shadowing FrameBuffer usage
A FrameBuffer *buffer is used to obtain the 'first' buffer from a
request which is used purely to identify the timestamp from the
metadata in two locations.

Rather than keep the FrameBuffer instance around, which then causes
further usages of FrameBuffers to be shadowed, store the timestamp
locally.

bf104042f9 ipa: raspberrypi: Re-use iterator variable
The function gauss_seidel2_SOR() makes use of a function scoped iterator
'i', for several loops, and has a precedence of re-using the function
scoped iterator declaration in the majority of cases, except the first
where it is declared in the loop scope before the function scope, and
later which aliases a new declaration.

Re-use the existing iterator variable for consistency, and to prevent
variable aliasing.

Introduce a CameraWorker class that runs an internal thread to wait

Fences completion is handled through a simple poll, similar in
implementation to the sync_wait() function provided by libdrm.

05cdef27ab libcamera: pipeline: simple: enable mplane devices using contiguous memory
The current simple pipeline handler refuses to work with capture devices
which have V4L2_CAP_VIDEO_CAPTURE_MPLANE flag set in the device capabilities
field. This is too restrictive, as devices supporting the multi-planar API
can be using contiguous memory for semi-planar and planar formats, and this
would just work without any changes to libcamera.

Drop the guard against MPLANE devices, and replace it with the check of
the number of planes in the format the simple pipeline handler is going to
use for capture. This will let MPLANE devices which don't use non-contiguous
memory for frame buffers to work with the simple pipeline handler.

The following code in SimpleCameraData::init() filters out the pixel formats
libcamera doesn't support:

	PixelFormat pixelFormat = videoFormat.first.toPixelFormat();
	if (!pixelFormat)
		continue;

So the check for the number of memory planes this patch adds would not
trigger until non-contiguous planar formats becomes supported in libcamera,
and video devices using these formats are enabled in the simple pipeline
handler. Then this check will remind one to review the simple pipeline
handler code.

of CameraStream instances to make sure they get deleted and all the
resources they have acquired get released.

35f726d4da android: camera_device: Add stream mapping log
To ease following how Android streams get mapped to libcamera ones
add a (quite verbose) printout before queueing a request to libcamera.

The output looks like:
 0 -  (320x240)[0x00000022] -> (320x240)[NV12] (direct)
 1 -  (640x480)[0x00000021] -> (640x480)[NV12] (internal)

de8304b116 android: camera_device: Use CameraStream buffers
Now that CameraStream that require internal memory allocation
have been instrumented with a FrameBuffer pool, use them to create
intermediate buffers in the CameraDevice.

b84e35dc97 android: camera_stream: Create buffer pool
Add a FrameBufferAllocator class member to the CameraStream class.
The allocator is constructed for CameraStream instances that needs
internal allocation and automatically deleted.

Allocate FrameBuffers using the allocator_ class member in the
CameraStream class at CameraStream::configure() time and add two
methods to the CameraStream class to get and put FrameBuffer pointers
from the pool of allocated buffers. As buffer allocation can take place
only after the Camera has been configured, move the CameraStream
configuration loop in the CameraDevice class after camera_->configure()
call.

The newly created pool will be used to provide buffers to CameraStream
that need to provide memory to libcamera where to deliver frames.

6c8837da5e android: camera_device: Make CameraStream configuration nicer
Loop over the CameraStream instances and use their interface to perform
CameraStream configuration.

Modify CameraStream::configure() to configure the android stream buffer
count and to retrieve the StreamConfiguration by index instead of
receiving it as a parameter.

e3393f147e android: camera_stream: Fetch format and size from configuration
Fetch the format and size of the libcamera::StreamConfiguration
associated with a CameraStream by accessing the configuration by
index.

This removes the need to store the libcamera stream format and sizes
as class members and avoid duplicating information that might get out
of sync.

It also allows to remove the StreamConfiguration from the constructor
parameters list, as it can be identified by its index. While at it,
re-order the constructor parameters order.

216030aa9d android: camera_stream: Retrieve Stream and Configuration
It's a common pattern to access the libcamera::Stream and
libcamera::StreamConfiguration using the CameraStream instance's
index.

Add two methods to the CameraStream to shorten access to the
two fields. This allows removing the index() method from the class
interface.

160bb0998b android: camera_stream: Construct with Android stream
Pass the android camera3_stream_t, and a libcamera::StreamConfiguration
to identify the source and destination parameters of this stream.

Pass a CameraDevice pointer to the CameraStream constructor to allow
retrieval of the StreamConfiguration associated with the CameraStream.

Also change the format on which the CameraDevice performs checks to
decide if post-processing is required, as the libcamera facing format is
not meaningful anymore, but the Android requested format should be used
instead.
