priseborough 10470b2dc1 AP_NavEKF2: fix bug in initialisation of declination co-variances 
Co-variances were being re-zeroed after being set. This meant that the initial declination learning was sensitive to measurement errors which could result in poor initial yaw accuracy.

priseborough 6b04a81b8d AP_NavEKF2: Fix plane in-flight yaw reset bug 
Fixes bugs that prevented planes being able to reset yaw to GPS to recovery from takeoff with a bad magnetoemter.

1) If the velocity innovation check had not failed by the time the in-air transition occurred, then the yaw reset would not be performed
2) The velocity states were not being reset
3) The non fly-forward vehicle (copter) reset could occur first and effectively lock out the fly-forward vehicle (plane) yaw check.

Murilo Belluzzo 3e1acdcbbf AP_HAL: Use atomic instead volatile on RingBuffer head/tail 
Volatile will provide protection to sequence re-ordering and guarantee
the variable is fetched from memory, but it won't provide the memory
barrier needed to ensure that no re-ordering (by either the compiler or
the CPU) will happen among other threads of execution
accessing the same variables.

For more info about this effect can be found on articles about
std::memory_order.

Murilo Belluzzo b7dd4dad64 AP_HAL: Fix ByteBuffer::reserve() breaking buffer state 
When using reserved(), the reserved memory cannot be read before it's
written, therefore we cannot update 'tail' until the caller of
reserved() is done writing.

To solve that, a method called 'commit()' was added so the caller can
inform that is done with the memory usage and is safe to update 'tail'.
The caller also has to inform the length that was actually written.

This solution was developed to work considering the usage context of
this class: 1 reader and 1 writer **only**.

Murilo Belluzzo 43d4012884 AP_HAL: Fix TOCTOU in ByteBuffer::peekiovec() 2016-07-08 13:10:16 -03:00
Murilo Belluzzo 9951b94d40 AP_HAL: Change the return type of 'peekiovec' 
Possible values are '0', '1' and '2' so uint8_t is a better fit. Also,
invert 'if' condition so it's clear that is returning 0, 1 or 2.
 2016-07-08 13:10:16 -03:00
Murilo Belluzzo 625f47def7 AP_HAL: Improve ByteBuffer::set_size 
So it doesn't delete and re-create the buffer if the size
happens to be the same. Still resets the buffer content.

Murilo Belluzzo e9e31172c0 AP_HAL: Simplify ByteBuffer::readptr logic 2016-07-08 13:10:16 -03:00
Leandro Pereira fbefe32017 AP_HAL: Add method to reserve space in the ring buffer 
Adds a method called `reserve()`, that will take a ByteBuffer::IoVec
array of at least two elements, and return the number of elements
filled out.  0 will be returned if `len` is over the total space of
the buffer; 1 will be returned if there's enough contiguous bytes in
the buffer; 2 will be returned if there are two non-contiguous blocks
of memory.

This method is suitable to be used with POSIX system calls such as
readv(), and is an optimization to not require temporary memory copies
while reading from a file descriptor.

Also modify the write() method to use reserve(), so that similar checks
are performed only in one place.
 2016-07-08 13:10:16 -03:00
Leandro Pereira e3b676ba89 AP_HAL: Add method to peek non-contiguous parts of a ByteBuffer 
Modify ByteBuffer class to have a `peekiovec()` method, that takes in a
`struct IoVec` array (similar to `struct iovec` from POSIX), and a
number of bytes, and returns the number of elements from this array
that have been filled out.  It is either 0 (buffer is empty), 1
(there's enough contiguous bytes to read that amount) or 2 (ring buffer
is wrapping around).

This enables using scatter-gather I/O (i.e. writev()), removing calls
to memcpy().  That's one call when no wrap-around is happening, and
two calls if it is.

Also, rewrite `ByteBuffer::peekbytes()` to use `peekiovec()`, so that
some of the checks performed by the former are not replicated in the
latter.

Andrew Tridgell 11975223dd AP_Motors: added H_RSC_POWER_NEGC and H_RSC_SLEWRATE 
this gives more control over throttle for petrol
helis. H_RSC_POWER_NEGC allows for a asymmetric V-curve, which allows
for less power being put into the head when landing or when sitting on
the ground. That can lead to significantly less vibration and chance
of ground oscillation. A heli not being flown with aerobatics does not
need to use high throttle at negative collective pitch.

The H_RSC_SLEWRATE allows for a maximum throttle slew rate to be
set. Some petrol motors can cut if the throttle is moved too
quickly. We had this happen at a height of 6m when switching from
ALT_HOLD to STABILIZE mode. It also lowers the chance of the blades
skewing in their holders with the sudden change of power when the heli
is disarmed. In general it is a bad idea to do instantaneous large
movements of a IC engine throttle.

Paul Riseborough 5c59922574 AP_NavEKF2: Fix bug that could publish bad compass offsets 
Magnetometer bias states will subject to larger errors early in flight before flight motion makes the offsets observable and the state variances reduce.
Adds a check on state variances.
Replaces the parameter check with a check of the actual filter fusion method being used.

Paul Riseborough 165335b9e3 AP_NavEKF2: Improve ability to tune magnetic field learning 
Allow different process noise to be set for body (sensor bias) and earth field states.
This allows a stable magnetometer bias estimate to be available at end of flight whilst still allowing for external magnetic anomalies during landing.
Adjust default values to give stable mag bias learning and fast learning of external anomalies.

Paul Riseborough 6523481c76 AP_NavEKF2: Improve tracking accuracy of output predictor 
Automatically use the highest gain consistent with a 5% overshoot to minimise RMS tracking errors.
Provide an alternative correction method for the position and velocity states that allows the user to specify the time-constant. This can be used to fine tune the output observer for for platform specific sensor errors and control loop sensitivity estimation noise.

Paul Riseborough dc6836988c AP_NavEKF2: Improve ground based magnetic anomaly protection for copter 
The toilet bowling check during early flight has been removed. This check caused problems where bad compass calibration was the cause of the toilet bowling and resetting to the compass was a bad option. The handling of simultaneous failed mag and velocity innovations is already handled outside the EKF by the failsafe.
A check for yaw errors due to a ground based magnetic anomaly has been introduced.

Gustavo Jose de Sousa 66f1ad9ed0 AP_HAL: Device: add support for read flag 
Many of our SPI and I2C sensors define the protocol of setting the most
significant bit of the register address in order to perform a read operation.
Thus, enable the use of a "read flag" that is ORed with the register's address.
Since this is an abstraction for general devices, it's a good idea to have zero
as the default value for that flag.

While at it, add documentation to read_registers().

Lucas De Marchi b8e3e549c7 AP_HAL_Linux: Perf: add debug method 
Test code for integration with another thread to pull data from internal

Lucas De Marchi 1727418dc9 AP_HAL_Linux: Perf: make lttng use internal fields 
Instead of creating a new object Perf_Lttng copying the necessaries
fields, just make a tighter integration with the internal perf counters
and re-use the same fields.
 2016-06-23 19:06:30 -03:00
Lucas De Marchi 619ce23799 AP_HAL_Linux: Perf: rework integration with other tools 
The idea is to leave the internal perf enabled all the time, like it is
in PX4, and then allow the integration with lttng on top. Next step
would be to runtime enable/disable only the perf counters we are
interested in.

This also changes the structure so it's easy to allow another thread to
pull data from the Perf object. A rw lock protects from addition of new
counters and an atomic unsigned int allows other threads to do a
lockless copy of the data.

In order for this to work the allocation was changed to use a single
memory pool instead of returning a calloc'ed data for each perf counter.
Since most of our counters are of ' elapsed' type, don't bother using a
smaller struct for the 'count' type

Lucas De Marchi 39d4fa2cf8 Revert changes to cmath according to gcc version 
Revert these commits:
	"AP_Common: gcc 4.9.2 behaves differently from 4.9.3"
	"AP_Common: this workaround for missing/cmath is also needed for gcc 4.9.3"

This breaks the build for PX4. The change is related to the libc, not
the compiler version. We have an workaround there based on compiler
version just because it's usual to have a more recent libc version when
you have a recent compiler.

Leonard Hall 4f0db2bc36 AP_Motors: learned THST_HOVER replace THR_MID 
This holds the estimated thrust required for the vehicle to hover
expressed as a number from 0 to 1.  0 will be equivalent to outputting
SPIN_MIN (which is a number from 0~1 but in the full output range) and 1 is equivalent to SPIN_MAX (also 0~1 but in the full output range)

Leonard Hall 5a8fc6283e AP_Motors: replace throttle_rpy_mix with throttle_avg 
AC_AttitudeControl now calculates throttle vs attitude control
prioritisation and simply provides overall maximum throttle (aka
throttle_avg) to the motors library
