Peter Barker c95348c1d9 SITL: Avoid run-time FPEs due to bad gyro settings if SIM_DRIFT_TIME is set to 0 
_gyro_drift essentially suffers a divide-by-zero if SIM_DRIFT_TIME is 0.  The gyro initialisation routines in AP_InertialSensor do not return once the generated NaN propogates back to them.

Lucas De Marchi b292873304 AP_InertialSensor: fix starvation in L3G4200D 
The main thread would always be blocked on the semaphore to read the
data from accelerometer and gyroscope. Especially if we have a slow
update of these values in _accumulate() due to the I2C transfer function
taking too much time: the timer thread would never give up the CPU,
causing starvation on the main thread.

This fixes the issue by reducing the critical region using a flip-buffer
so _accumulate() can work on its own copy of the data. Now that the
critical region is smaller, also avoid the semaphore and use a spinlock
instead.

Andrew Tridgell b17878c8c4 SITL: lower default GPS delay to 0.2 seconds

Andrew Tridgell d7249cc1e6 AP_AHRS: only use EKF for plane and rover if all data available

Lucas De Marchi 996739df12 AP_Compass: Do not panic if compass is not found 
Copter uses 2 compasses for linux configuration, but one of them may not
be available. Do not panic if a AK8963 isn't found.

 2015-04-14 09:25:35 +10:00
Lucas De Marchi f049c8e4c5 AP_HAL_Linux: remove needless call to mlockall() 
All threads share the same address space and have the same pages locked
into memory so it's not necessary to call mlockall() for each of them.

Grepping /proc/<tid>/status gives the same VmLck for all of them, even
when only the main thread locks the memory:

    # for i in `seq 477 482`; do \
	name=$(cat /proc/$i/comm); \
	vm=$(cat /proc/$i/status |grep VmLck); \
        echo -e "$name\t$vm"; \
    done

Lucas De Marchi b7355dc62b AP_HAL_Linux: set thread name for ease debug 
Use pthread_setname_np() to set thread name so it's easier to debug
what't going on with each of them. This is the example output of the
relevant par of "ps -Leo class,rtprio,wchan,comm":

Lucas De Marchi e3d78b8960 AP_HAL_Linux: fix passing callback to member function 
It's undefined behavior to pass the callback to pthread to a class
member like we were doing. Refactor the code so the callbacks are static
members.

This fixes the following warnings:

Lucas De Marchi 62c2f737d5 AP_HAL_Linux: fix setting RT priorities 
LinuxScheduler::init() was not really working as it should. This was the
result of "ps -Leo class,rtprio,wchan,comm | grep ArduCopter":

FF      12 futex_ ArduCopter.elf
FF      12 usleep ArduCopter.elf
FF      12 hrtime ArduCopter.elf
FF      12 poll_s ArduCopter.elf
FF      12 hrtime ArduCopter.elf
FF      12 hrtime ArduCopter.elf

As can be seen all the threads run with the same priority, the one of the main
thread. There were basically 2 mistakes:

	1) pthread_attr_setschedpolicy() needs to be called before
	   pthread_attr_setschedparam(). Otherwise the latter will just return
	   an error and not set the priority

	2) pthread_create() defaults to ignore the priority and inherit the
	   it from the parent thread. pthread_attr_setinheritsched() needs to
	   be called to change the behavior to PTHREAD_EXPLICIT_SCHED. See
	   pthread_attr_setinheritsched(3) for an example program to test the
	   behaviors.

Also, it's undefined behavior to call pthread_attr_init() several times on the
same pthread_attr_t. Although we could reutilize the same attribute without
calling  pthread_attr_init() again, lets refactor the code a little bit, so all
the pthread calls are in a single place. Then also call pthread_attr_destroy()
when we are done.

Andrzej Zaborowski 132cdc4916 Motors: Use _motor_to_channel_map in tricopter consistently. 
In AP_MotorsTri.cpp the AP_MOTORS_MOT_1, _2 and _4 constants are
always mapped to actual output channels through _motor_to_channel_map
while the _CH_TRI_YAW is not, but there were a few inconsistencies
in this that could lead to things like PWM min and max values being
set on wrong channels.

It looks like all in all _motor_to_channel_map being in PROGMEM
probably doesn't help save memory and I'm not sure how useful it is
in the first place but regardless the usage should be consistent.

When performing a u-turn in AUTO (waypoints are 180deg turn from each other) sometimes the aircraft can't decide to turn left or right and wobbled back and forth a couple times. There was existing code to solve this but it was not executing all the time like when in LOITER mode. Frankly, I don't understand the criteria that was required to make it execute and i suspect there is still a gremlin in that logic but just executing the check all the time makes prevents the wobble behavior.

Paul Riseborough 10f050c53b AP_NavEKF: Prevent baro drift causing toilet bowling 
The magnetic field states are reset once at 1.5 metres and again at 5 metres. This height check was using the height at the first arm event as the reference. In the situation where there is baro drift and extgended time between the first arm event and flight, this can cause the magnetic field state to be reset when on the ground. If this happens when flying off a metallic surface, the resultant heading errors can cause sever toilet bowling.
