Hi Paul and Laurent,
Some reflection from ChromeOS integration's perspective.
Currently, ChromeOS separates HAL and 3A into distinct upstart services.
The upstart will launch each one in minijail with different settings.
The reason is that we'd like the 3A component to have more restrictions
than the HAL process, since it usually contains a closed sourced library.
The upstart will launch them separately and they will try to connect to
each other by a specific named socket.
On the socket connection, they communicate by a predefined mojo interface.
For vendors, we require the close sourced library to expose symbols
identical to the interface.
In my opinion, ChromeOS doesn't need to stick to mojo communication, and we
can apply this solution.
But we hope to maintain the two-service structure, and thus something I can
think of might influence.
I don't have a clear opinion for them, but I'd like to add them here for
discussion.
1. Since the 3A component is launched by an independent service and in our
case it should be ipa_proxy_worker. ChromeOS needs a way to control the
libcamera not to fork the ipa_proxy_worker, but to connect to a predefined
named socket. Maybe by specific build args for ChromeOS or an extended API
to its hal adaptor.
2. Because 3A is close-sourced, we expected it to crash for unknown
reasons. In this case, the upstart service will respawn the 3A process, and
the HAL process should be able to detect it and try to reconnect, assuming
3A is the server side of the socket.
3. Sometimes the HAL process might crash too :). The best case is that the
respawned HAL can reconnect to 3A again. Or for simplicity, 3A can exit()
on disconnection and assume upstart will restart everything.
4. This one may not be an actual problem but just a concern. For vendors,
we require the close sourced library to expose the same symbols defined by
us.
The definition:
https://chromium.googlesource.com/chromiumos/platform2/+/refs/heads/master/camera/include/cros-camera/camera_algorithm.h
For existing ChromeOS products, the binaries are deployed and following the
ChromeOS API. On the other hand, libcamera has more freedom on defining the
3A API. In the ideal situation, we could discuss with every vendor to
support libcamera's API too, but I have to admit that it depends on the
vendor, and is not always possible. If this happens, and the libcamera IPA
API can be easily translated to ChromeOS IPA API, we can add an
intermediate layer to adapt the existing binaries, and avoid the problem.
For other platforms we don't have products, we don't need to worry about
it, but It may affect rockchip, ipu3/ipu6, Mediatek and maybe Qualcomm
devices.
Thanks for the implementation Paul, the idea to reuse mojom parser is so
clever.
