Lucas De Marchi 590539f674 AP_HAL_Linux: implement threaded I2C 2016-07-30 00:55:27 -03:00
Lucas De Marchi 37de995960 AP_HAL: update Device interface for periodic tasks 
Replace the previous not-implemented interface with a set of new methods
that can be resonably implemented:

    - register_periodic_callback() now receives a functor returning bool
      to easily allow "oneshot" timers

    - adjust_periodic_callback() allows the caller to change the timer
      for a specific handle. This way drivers like MS5611 can adjust the
      timer depending on its state machine: the time to sample
      temperature is smaller than the time to get a pressure sample

    - add unregister_callback(): since we have an opaque pointer, we
      can't tell the user to just delete it in order to unregister the
      callback

Lucas De Marchi 01452bf922 AP_HAL: SPIDevice: add fullduplex method 
This method is needed when we want to transfer both tx and rx at the
same time, as opposed to common cases for sensors in which they are like
in the I2C interface: half-duplex.

Minor changes to follow coding style and improve readability:

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.

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().
