* Changed the method of checking and setting the server file lock on Posix to avoid conditions where the server can indicate that it is running but still hasn't finished it's initialization
The static object is destroyed on at_exit while threads might still be
inside a CS. This can lead to a hanging process.
Cleaner would be to gracefully stop the threads.
According to https://linux.die.net/man/3/pthread_cond_destroy:
Attempting to destroy a condition variable upon which other threads are
currently blocked results in undefined behavior.
- new modules/simulation directory to collect all simulators and related modules
- new Tools/simulation directory to collect and organize scattered simulation submodules, scripts, etc
- simulation module renamed to simulator_mavlink
- sih renamed to simulator_sih (not a great name, but I wanted to be clear it was a simulator)
- ignition_simulator renamed to simulator_ignition_bridge
- large sitl_target.cmake split by simulation option and in some cases pushed to appropriate modules
- sitl targets broken down to what's actually available (eg jmavsim only has 1 model and 1 world)
- new Gazebo consistently referred to as Ignition for now (probably the least confusing thing until we fully drop Gazebo classic support someday)
* sih: Move sih out of work queue
This reverts commit bb7dd0cf00.
* sih-sim: Enable sih in sitl, together with lockstep
* sih-sim: new files for sih: quadx and airplane
* sih: Added tailsitter for sih-sitl simulation
* sitl_target: Added seperate target loop for sih
* jmavsim_run: Allow jmavsim to run in UDP mode
* lockstep: Post semaphore on last lockstep component removed
* sih-sim: Added display for effectively achieved speed
* sih: increase stack size
* sih-sim: Improved sleep time computation, fixes bug of running too fast
* sitl_target: place omnicopter in alphabethic order

This adds the env option PX4_FUZZ which runs the LLVM libFuzzer which
throws random bytes at mavlink_receiver using MAVLink messages over UDP.
The MAVLink messages that are being sent are valid, so the CRC is
calculated but the payload and msgid, etc. are generally garbage, unless
the fuzzing gets a msgid right by chance.
As I understand it, libFuzzer watches the test coverage and will try to
execute as much of the code as possible.
This is already removed from nuttx, and in posix the size of s->last_times
can be just checked with sizeof()

This changes px4_task_spawn_cmd to match the NuttX task_spawn. It adds
the task name as argv[0]. See example below:
px4_task_spawn_cmd("task_name",
SCHED_DEFAULT,
SCHED_PRIORITY_DEFAULT,
1024,
(px4_main_t)&Something::start_helper,
(char *const *)argv);
with:
argv[0]: "something"
argv[1]: "start"
argv[2]: nullptr
becomes in Something::start_helper:
argv[0]: "task_name"
argv[1]: "something"
argv[2]: "start"
argv[3]: nullptr
* add basic mlock support to increase stability when system is under high load and RAM is almost full
* mainly about minimizing or completely eliminating RAM page swap time
- drivers/tone_alarm: move to ModuleBase and purge CDev (/dev/tone_alarm0)
- drivers/tone_alarm: only run on tune_control publication (or scheduled note) rather than continuously
- drivers/tone_alarm: use HRT to schedule tone stop (prevents potential disruption)
- msg/tune_control: add tune_id numbering
- systemcmds/tune_control: add "error" special case tune_id
- move all tune_control publication to new uORB::PublicationQueued<>
- start tone_alarm immediately after board defaults are loaded to fix potential startup issues
- for SITL (or other boards with no TONE output) print common messages (startup, error, etc)
Nuttx now supports sh and source (.)
sh will open a new process for each invocation.
This means the child can not modify the parent
env. So we must use . to matain how nuttx worked.
Since rc.vehicle_setup is used in both we use
source and alis as we did with sh.
- Nuttx only process all suspend & resume scheduling notes when top is running, otherwise only track IDLE
- convert cpuload and print load to c++
- delete unused fields from print_load struct
- update hrt_store_absolute_time (previous unused)
- always check with state machine before reboot/shutdown
- respect BOARD_HAS_POWER_CONTROL (shutdown from command, low battery, power button)
- px4_shutdown_request add optional delay and always execute from HPWORK
- px4_shutdown_request split out px4_reboot_request
When this triggered it actually just kept printing
"floating point exception" and never recovered. By removing this we can
at least catch it with a core dump, in CI as well as locally.
