5fb28bfe74 libcamera: pipeline: rkisp1: Don't rely on bufferCount
Currently the rkisp1 pipeline handler relies on bufferCount to decide on
the number of parameter and statistics buffers to allocate internally.
Instead, the number of internal buffers should be the minimum required
by the pipeline to keep the requests flowing, in order to avoid wasting
memory.

Stop relying on bufferCount for these numbers and instead set them to
kRkISP1MinBufferCount.

521177161a pipeline: rkisp1: Properly handle the bufferCount set in the stream configuration
The StreamConfiguration::bufferCount is reset to a hardcoded value of 4
in RkISP1Path::validate(). Keep the minimum value of 4 but do not reset
it, if it was set to a larger value.  This allows the user to set
bufferCount to an arbitrary number of buffers which then can be
allocated for example by the FrameBufferAllocator. If the bufferCount is
set to a smaller value it gets reset to kRkISP1MinBufferCount again and
the configuration is marked as adjusted.

0c5523c908 libcamera: pipeline_handler: Move waitingRequests_ into camera class
The waiting requests of one camera should not be able to influence

1ef8981c39 libcamera: pipeline: rpi: Do not set timestamps to 0 if unavailable
`SensorTimestamp` and `FrameWallClock` should always be available. However,
if that ever changes or they are not available for some unforeseen reason,
setting them to 0 is not ideal. That makes it more complicated for the
application to detect these cases (since they have to check the existence
either way), and if an application blindly assumes e.g. that `SensorTimestamp`
is monotonically increasing, then receiving a timestamp of 0 will likely
cause issues.

So simply omit them from the request metadata if they are not available.

5f94209b1d pipeline: rpi: Fix for enumerating the media graphs
When there are multiple entities between the sensor and CFE device (e.g.
a serialiser and deserialiser or multiple mux devices), the media graph
enumeration would work incorrectly and report that the frontend entity
was not found. This is because the found flag was stored locally in a
boolean and got lost in the recursion.

Fix this by explicitly tracking and returning the frontend found flag
through the return value of enumerateVideoDevices(). This ensures the
flag does not get lost through nested recursion.

This flag can also be used to fail a camera registration if the frontend
is not found.

a29c53f6a6 meson: Use libyaml wrap file from wrapdb
Use the libyaml wrap file from the meson wrapdb instead of
creating the wrap file manually and using the cmake module.
This provides better integration with meson, such as the
`force_fallback_for` built-in option.

This is also needed because the upstream CMakeLists.txt is
out of date, failing with a sufficiently new cmake version:

    CMake Error at CMakeLists.txt:2 (cmake_minimum_required):
    Compatibility with CMake < 3.5 has been removed from CMake.

The above is nonetheless addressed by https://github.com/yaml/libyaml/pull/314,
but the project seems a bit inactive at the moment.

The wrap file was added using `meson wrap install libyaml`,
and it can be updated using `meson wrap update libyaml`.

`default_library=static` is used to match the behaviour of the
previously used cmake build. `werror=false` needs to be set
because libyaml does not compile without warnings, and that
would abort the build process otherwise.

amount of sink and source pads.

But for some other imx SoCs, such as i.MX8QM or i.MX95, crossbar is not
symetric anymore.

Since each crossbar source is already captured as a pipes_ vector entry,
we use pipes_ vector's size to compute 1st source index.

  "1st source index" = "total number of crossbar pads" - pipes_.count()

5b7c83d8cc libcamera: process: Pass stderr and reserve stdin and stdout fds
When a child process is started from Process::start(), the file
descriptors inherited from the parent process are closed, except
the ones explicitly listed in the fds[] argument.

One issue is that the file descriptors for stdin, stdout and stderr
being closed, the subsequent file descriptors created by the child
process will reuse the values 0, 1 and 2 that are now available.
Thus, usage of printf(), assert() or alike may direct its output
to the new resource bound to one of these reused file descriptors.
The other issue is that the child process can no longer log on
the console because stderr has been closed.

To address the 2 issues, Process:start() is amended as below:
- Child process inherits from parent's stderr fd in order to share
the same logging descriptor
- Child process stdin, stdout and stderr fds are bound to /dev/null
if not inherited from parent. That is to prevent those descriptors
to be reused for any other resource, that could be corrupted by
the presence of printf(), assert() or alike.

32905fdd0b libcamera: process: Use _exit in child process
Use _exit() in child process in case of execv() error. That is to
avoid interfering with the parent process as exit() may call its
atexit() handlers and flush its io buffers.

`appendPOD()` does a single insertion, so if only a single `appendPOD()`

d997e97512 utils: codegen: Make users depend on controls.py in meson
Currently, modifying `controls.py` does not make those build targets dirty
that use a script that includes it (e.g. `gen-controls.py`) because meson
has no knowledge of this dependency. Add `depend_files` to each
`custom_target()` invocation to fix this.

Ideally it would be possible to attach this dependency to `gen_controls`,
`gen_gst_controls`, etc. objects themselves, so that repetition is
avoided, but this does not seem possible at the moment.

efdbe39698 libcamera: controls: Fix ControlInfoMap::count(unsigned int)
The two overloads of `find()` and `at()` have the same behaviour
regardless of the argument type: `unsigned int` or `const ControlId *`.
However, `count()` is not so because `count(unsigned int)` only checks
the `ControlIdMap`, and it does not check if the given id is actually
present in the map storing the `ControlInfo` objects.

So `count()` returns 1 for every control id that is present in the
associated `ControlIdMap` regardless of whether there is an actual
entry for the `ControlId` associated with the given numeric id.

Fix that by simply using `find()` to determine the return value.
