Previously uORB queue size was an awkward mix of runtime configurable (at advertise or IOCTL before allocate), but effectively static with all queue size settings (outside of test code) actually coming from the topic declaration (presently ORB_QUEUE_LENGTH in the .msg). This change finally resolves the inconsistency making the queue size fully static.
Additionally there were some corner cases that the muorb and orb communicator implementation were not correctly handling. This PR provides fixes for those issues. Also correctly sets remote queue lengths now based on the topic definitions.
* Made setting of uORB topic queue size in based on topic definition only
* Fixes to the ModalAI muorb implementation
* Removed libfc sensor from format checks
* msg/TransponderReport.msg ORB_QUEUE_LENGTH 8->16 (was set to higher in AdsbConflict.h

* uORB orb_stat() and update(uint64_t *time, void *dst) are now obsolete and have been deleted
* mavlink messages add more advertised checks in streams get_size() check to improve data rate calculation across different scenarios
and remove the px4_ prefix, except for px4_config.h.
command to update includes:
for k in app.h atomic.h cli.h console_buffer.h defines.h getopt.h i2c.h init.h log.h micro_hal.h module.h module_params.h param.h param_macros.h posix.h sem.h sem.hpp shmem.h shutdown.h tasks.h time.h workqueue.h; do for i in $(grep -rl 'include <px4_'$k src platforms boards); do sed -i 's/#include <px4_'$k'/#include <px4_platform_common\/'$k/ $i; done; done
for in $(grep -rl 'include <px4_config.h' src platforms boards); do sed -i 's/#include <px4_config.h/#include <px4_platform_common\/px4_config.h'/ $i; done
Transitional headers for submodules are added (px4_{defines,log,time}.h)
Existing users of orb_exists:
- logger (dynamic subscribe to multi-instances)
- mavlink (orb subscription)
- sdlog2
- preflightcheck (check for home_position)
- wait_for_topic shell command (it's not used)
- orb_group_count() (sensors: dynamic sensor addition)
All use-cases benefit from the changed semantics: they are really only
interested if there is a publisher, not another subscriber.
This adds two uORB API calls:
- orb_advertise_queue
- orb_advertise_multi_queue
Both add a queue_size parameter to define a maximum number of buffered
item. The existing orb calls use all a queue size of one and thus their
behavior is unchanged. If a writer publishes too fast, the oldest elements
from the queue are silently dropped.
The returned timestamp is always the one from the latest message in the
queue.
Queue size can be set via ioctl during advertisement phase. After that it
cannot be changed anymore.
