Peter Barker c917cd4dbb AP_HAL_Linux: make a static-const hal references references to external symbol 2020-03-03 10:12:14 +11:00
Andrew Tridgell 67bd4ed396 AP_HAL_Linux: use take_blocking instead of HAL_SEMAPHORE_BLOCK_FOREVER
this makes for cleaner and smaller code as the failure case is not
needed

Peter Barker cbe73b91d5 AP_HAL_Linux: correct format-string warnings
Using the string template to determine the size of the array to print
into strikes issues as varargs passes the stack variables as integer
types, so the perceived range is larger.

Lucas De Marchi ad8ab97725 AP_HAL_Linux: SPIDevice: compile out debug stuff
This should at most be behind a flag. If the device is being used by
other process/drivers, it's a problem with that specific user/distro:
don't penalize everybody else. Besides, changing the mode is not atomic
and nothing guarantees the other side doesn't get scheduled and change
it back before we get to run.

Lucas De Marchi 2c6dd64c67 AP_HAL_Linux: create one thread per spi bus rather than device
Do not create one thread per chardev (i.e. bus + kernel's chip select).
Since the shared resources are actually the bus controller and the bus
lines, it makes sense to have 1 thread per bus, otherwise it will just
get locked again on the mutex in the kernel side.

Lucas De Marchi 49d08ba72a Global: remove minlure
Minlure is a port of ArduPilot to Minnow Board connected to daughter
board. Very few of those were produced and nobody is flying with it.

It served its purpose and all the the improvements to ArduPilot remain
regardless of it not being supported anymore. Now it's just adding
maintenance work with no clear benefit, so pull the plug.

It's not being sold, there are just a few (different) engineering

that were pushing it.

This was there for compatibility with I2CDriver and SPIDriver. We don't
use them anymore so we can remove the compat method.

Lucas De Marchi 61ef653181 AP_HAL_Linux: implement SPIDevice
The way this code is structured is a little bit different from the
SPIDriver implementation:

 - We only open the bus once, no matter how many devices we have in it

 - There's a single transfer() method which uses half-duplex mode
   instead of full duplex. The reason is that for all cases in the
   codebase we are using half-duplex transfers using the full-duplex
   API, i.e. a single SPI msg with both tx and rx buffers. This is
   cumbersome because the buffers need to be of the same size and the
   receive buffer using an offset of the same length as the actux data
   being written. This means the high level APIs need to copy buffers
   around.

   If later we have uses for a real full duplex case it's just a matter
   of adding another transfer_fullduplex() method or something like
   this.

 - The methods are implemented in the SPIDevice class instead of having
   proxy methods to SPIDeviceManager as is the case of SPIDriver

Also from now on we refer to the SPIDriver objects as "descriptors"
because they have the parameters of each device in the
SPIDeviceManager::devices[] table. When SPIDeviceDriver is completely
replaced we can rename them to SPIDeviceProperties.
