Propagate the error if spa_system_eventfd_create() fails. Also copy
errno before calling spa_log_debug() in spa_system_eventfd_create() to
make sure it is not overwritten.
The rate we get from dlls can have a subsample precision. However,
the check for using process_copy is in sample precision. This means
that an adaptive stream will oscillate rather then lock into the
exact rate.
We would timestamp within an unlikely block, which would introduce
additional jitter to current_time, which would have an impact on
the performance of the timer sensitive code.
Previously both `impl_on_notify_events()` and `process_{device,card}()`
called `check_access()`. Avoid that by merging `ACTION_ADD` and
`ACTION_DISABLE` into a single `ACTION_CHANGE` and let `process_{device,card}()`
call `check_access()` and decide what to do.
Split up `process_{device,card}()` to have a separate function that does
the lookup based on the udev device, and only use that when there is
no available reference to the actual device/card object.
`IN_IGNORED` event is sent whenever the watch is removed,
which includes when the entity is deleted among other things,
so watch that instead of the more specific `IN_DELETE_SELF`.
Add a MAPPABLE data flag that hints that the fd in the data is mappable
with a simple mmap/munmap. Normally, DmaBuf is not mappable like that
unless explicitly indicated with this flag.
Set the MAPPABLE flag on the DmaBuf from v4l2 and libcamera fd.
When asked, mmap the buffer memory in all cases when the MAPPABLE
flag is set.
This solves the case where v4l2 has exported DmaBuf and is streaming to
node A and then node B links but doesn't get automatically mmaped
memory.
Fixes#3840
When the invoke ringbuffer is full, sleep a little and try again.
Add an option to set the retty timeout, setting this to 0 restores
the old behaviour of returning -EPIPE.
Most callers don't check the return values and might assume the invoke
call is queued or executed, which could cause crashes or leaks.
When the queue overruns, it's better to log a warning and hope that the
problem is resolved soon. We might abort or return the error to the
caller later if we want to break the retry loop.

The file is moved into a new "include-private" directory. This is done
because otherwise adjustments would have to be made to the list of installed
headers, the way include tests currently work and which files are
used for generating documentation.
Fix some sanity checks and add mtu check. Don't use
spa_return_val_if_fail here as it can spam stderr.
The buffer size check in codec_encode can't be hit.
Don't show a "codecless" profile for HFP, similarly as we do for A2DP.
Simplify codec handling: for HFP/A2DP there's at most one transport for
each profile, so no need to check it has right codec. There's also no
need for "fallback profile", we always just emit nodes for the transport
we find.
Always reevaluate the rate matching even when we did not change the
follower state.
It is possible that we were a follower from some node with the same
clock and now become a follower of a node with a different clock. The
follower state doesn't change but we need to activate the rate matching
logic in that case.
Fixes rate matching in pro audio (playback) when capture and playback
are moved to another driver.
The AAC-ELD support was not properly tested on devices. In theory it
should be OK, but it's untested.
Bump it down in priority so it won't be selected by default.
Also log info on FDK-AAC AAC-ELD support status.
