[libcamera-devel] [PATCH 0/6] Add support for blocking method invocation

[Jacopo Mondi]

Hello,
   this small series generalise the blocking method invocation implemented in
the Android Camera HAL to be a generic libcamera core concept.

Patch 1/6 contains the definition of message invocation types, which I've been
suggested to 'be insipired' from the QT defined ones. unfortunately I'm not sure
how to handle 3 on 5 of them, so I made it clear in the documentation which
shall be changed in the v2 of this series.

2/6 passes the newly defined message invocation type to the
Object::invokeMethod() operation, 3/6 creates a synchronization class for
Objects that wraps an std::conditional_variable and 4/6 uses them in the method
invocation path of the Object and Message classes to block until a method has
not been invoked on the receiver Object.

Patch 5/6 makes the objec-invoke test use the newly introduced blocking method
invocation mode, and patch 6/6 removes the ThreadRPC class from the Android
camera HAL implementation.

Thanks
   j
