* sdlog2: move from STAT.MainState to COMM.MainState
This fixes a bug where vehicle_system_status and the commander internal
state were conflicting.
This will need adaptations in logging tools.
* sdlog2: don't bother changing STAT.MainState
For compatibility reasons, let's stick to the used log field (but still
fix the bug where the buffer (union) was overwrittern.
in detail:
- in the write method: the following are not necessarily atomic operations:
_last_update = hrt_absolute_time();
_generation++;
- appears_updated() was called with a lock held in some cases, but not
in ioctl
- use the SmartLock class, so that unlock() is not needed before every
return call. Makes it less error prone
This fixes a race condition: uORB::Manager::get_instance() is used in a
multi-thread context, but the singleton initialization was not thread-safe.
Further, this avoids having to check for nullptr every time the singleton
is accessed.
uORB::Manager::initialize() is called when uorb is started. No one else
accesses the singleton before that point, because it is only used in the
orb_* methods, and in muorb. Both require uorb to be started already when
they are used.
This is necessary when using multiple instances of a topic. However it does
not free the underlying resources, as it is assumed they will be used again
at a later point.
* Qflight: add intersil sensor driver
* df_isl_wrapper: change driver lib name to isl
* posix-config: add df_isl_wrapper start command to eagle startup
* isl_wrapper: cleanup isl wrapper
* isl: remove unused option -R
* isl: change the driver name to isl29501
* DriverFramework: updated submodule again
This is to get the latest `make fix-style` changes.
* df_isl29501_wrapper: rename wrapper all the way
- either sensor combined or the replay topic where copied into
the union buffer but at times the memory was overwritten by other
topics which updated below
- this change makes sure that the two topics are copied into the union
buffer at the correct location in the code
