• 355c1a14d   iio: kfifo_buf: Implement data_available() callback ... Browse Code »

  This patch implements the data_available() callback for the kfifo buffer instead
  of using the stufftoread flag. The kfifo used by the buffer already knows
  whether it is empty or not based on the position of its read and write pointer.
  Using this makes it a lot easier to tell whether data is available or not and it
  is not necessary to take special measures to ensure that no race conditions
  between reading and writing from the buffer occur.

  Note, that we still have to take the buffers lock to protect against concurrent
  resizeing of the kfifo.

• 647cc7b9b   iio: Add data_available callback for buffers ... Browse Code »

  This patch adds a new data_available() callback to the iio_buffer_access_funcs
  struct. The callback is used to indicate whether data is available in the buffer
  for reading. It is meant to replace the stufftoread flag from the iio_buffer
  struct. The reasoning for this is that the buffer implementation usually can
  determine whether data is available rather easily based on its state, on the
  other hand it can be rather tricky to update the stufftoread flag in a race free
  way.

• 978f47d64   VME: Provide access to VME bus enumeration and fix vme_user match function ... Browse Code »

  The match function for vme_user is completely wrong. It will blindly bind
  against the first VME slot on each bus (at this point that would be just the
  first bus as the driver can only handle one bus).

  The original intention (before some major subsystem changes) was that the
  driver bind against the slot to which the bridge was attached in the VME
  system and to the bus(es) provided via the "bus" module parameter.

  To do this cleanly (i.e. without poking arround in the subsystems internal
  stuctures) a functionality has been added to provide access to the bus
  enumeration.
