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.

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

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.

Lucas De Marchi 29b667efdf AP_HAL_Linux: remove useless mlock of stack 
In Linux the default stack size is always greater than 32k, either 2MB
or 8MB depending on the architecture. There's no point in creating a
function to lock 32k.

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.

Tom Pittenger 9ecbd0e30f AP_L1_Control: fixed uTurn-wobble 
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.

Paul Riseborough b9b6938b1d AP_NavEKF: Add ability to start using GPS in-flight 
Improve the quality of the GPS required to set an EKF  origin
Eliminate repeated update of origin height - origin height updates once when EKF origin is set.
Operation in GPS mode is linked to setting of origin
 2015-04-03 15:15:09 -07:00
Paul Riseborough 98fa918b84 AP_NavEKF: Add new compass learning option 
Enables compass learning to be on continuously for non-position hold operation

Paul Riseborough a607eb8469 AP_NavEKF: Reduce the GPS glitch tether length from 100 to 50m 2015-04-03 15:15:08 -07:00
Paul Riseborough 496d31ab83 AP_NavEKF: Reduce max time Copters can reject GPS 
The maximum time copters can reject GPS has been reduced from 10 to 7 seconds as flight logs have show that inertial dead reckoning with vibration and calibration errors is not good enough to support 10 seconds without aiding.
 2015-04-03 15:15:08 -07:00
Paul Riseborough 8c2029d896 AP_NavEKF: Accel bias learning improvements 
Speed up pre-flight learning

 2015-04-03 15:15:08 -07:00
Paul Riseborough 19d1b3b813 AP_NavEKF: Update EKF origin height whilst disarmed 
This patch causes the EKF to update the height of its origin each time it receives a valid GPs message whislt disarmed.
The resultant EKF origin height represents the height of the zero baro alt datum relative to the GPS height datum.
 2015-04-03 15:15:08 -07:00
Paul Riseborough 70afcd7e70 AP_NavEKF: Add second stage alignment of yaw and earth field states 
Flight tests have shown that the magnetic field distortion associated with flight from steel structures can extend 3m or higher. To counteract this, a second and final yaw and magnetic field alignment has been added which is activated when the height exceeds 5m for the first time.

Paul Riseborough ed9c05cf2a AP_NavEKF: Remove logic used to delay fusion for load levelling 
Logic used to delay optical flow and airspeed fusion to prevent it occurring on the same time step as magnetometer fusion has been removed. This is no longer required to efficiency improvements made at the firmware level.
 2015-04-03 15:15:07 -07:00
Paul Riseborough c0d23ffc30 AP_NavEKF: Filter accuracy and stability improvements 
Improvements in PX4 firmware have reduced the computational load  and mkae the previous practicwe of splitting magnetometer and optical flow fusion across multiple time steps unnecessary and make it possible to perform a covariance prediction prior to fusing data on the same time step. This patch:

1) Ensures that a covariance prediction is always performed prior to fusion of any observation
2) Removes the splitting of magnetometer fusion so that fusion of the X,Y and Z components occurs on the same time time step
3) Removes the splitting of optical flow fusion so that fusion of X and Y components occurs on the same time step

priseborough 9a797a5d49 AP_NavEKF: Use GPS reported speed accuracy if available 
UBlox receivers report an estimate of the speed accuracy that tests show correlates well to speed glitches. Using this to scale the GPS velocity observation noise will reduce the effect of bad GPS velocity data.
