staging: vchiq: Fix refcounting bug in buffer_from_host()

2020-07-28T08:05:33+00:00

If we fail to queue the buffer then it can never be dequeued.  This can
lead to a forever loop in stop_streaming() when we wait for everything
to finish.

staging: vchiq: Move vchiq.h into include directory

2020-07-01T13:47:08+00:00

To make the separation clear between vchiq's header files and vchiq.h,
which is to be used by services and is the 'public' API, move it into a
dedicated includes directory.

staging: vchiq: Move defines into core header

2020-07-01T13:47:08+00:00

Those are only used in the core vchiq code, while present in vchiq's
'public' API header. Move them into the right place.

staging: vchiq: Use vchiq.h as the main header file for services

2020-07-01T13:47:08+00:00

This used to be vchiq_if.h but vchiq.h is more concise for an include
file that will hopefully be in the future in the includes directory.

staging: vchiq: Move conditional barrier definition into vchiq_core.h

2020-07-01T13:47:08+00:00

The barrier is only used by core code. So keep the barrier definition in
the core header.

staging: vchiq: Get rid of vchi

2020-07-01T13:47:08+00:00

All the functions that vchi currently provides are a 1:1 mapping to its
vchiq counterparts. Get rid of vchi altogether and use vchiq's on all
services.

In the process also get rid of the vchi directory, as the only remaining
file was a TODO file, which now lives in the parent directory.

staging: vchi: Move vchi_queue_kernel_message() into vchiq

2020-07-01T13:47:07+00:00

We can't really merge it with vchiq_queue_message() as it has internal
users that will not benefit from the retry mechanism
vchiq_queue_kernel_message() uses. So, for the sake of getting rid of
vchi, move it into vchiq.
