      ALSA: firewire-lib: move PCM substream constraint to AM824 layer · bc8500da
      Takashi Sakamoto authored
      In IEC 61883-6, PCM frames are transferred in Multi Bit Linear Audio data
      channel. The data channel transfers 16/20/24 bit PCM samples. Thus, PCM
      substream has a constrain about it.
      
      This commit moves codes related to the constraint from packet streaming
      layer to AM824 data block processing layer.

      ALSA: firewire-lib: rename parameter setting function for AM824 with FDF field · 51c29fd2
      Takashi Sakamoto authored
      The value of FDF field in CIP header is protocol-dependent. Thus, it's
      better to allow data block processing layer to decide the value in any
      timing.
      
      In AM824 data format, the value of FDF field in CIP header indicates
      N-flag and Nominal Sampling Frequency Code (sfc). The N-flag is for
      switching 'Clock-based rate control mode' and 'Command-based rate control
      mode'. In our implementation, 'Clock-based rate control mode' is just
      supported. Therefore, When sampling transfer frequency is decided, then
      the FDF can be set.
      
      This commit replaces 'amdtp_stream_set_parameters' with
      'amdtp_am824_set_parameters' to set the FDF. This is the same timing
      to decide the ration between the number of data blocks and the number of
      PCM frames.

      ALSA: firewire-lib: add data block processing layer for AM824 format · 5955815e
      Takashi Sakamoto authored
      This commit adds data block processing layer for AM824 format. The new
      layer initializes streaming layer with its value for fmt field.
      
      Currently, most implementation of data block processing still remains
      streaming layer. In later commits, these codes will be moved to the layer.

      ALSA: firewire-lib: add helper functions as interfaces between packet streaming layer and data block processing layer
      
      ALSA PCM framework uses PCM buffer with a concept of 'period' to
      synchronize userspace operations to hardware for nearly-realtime
      processing. Each driver implements snd_pcm_period_elapsed() to tell across
      of the period boundary to ALSA PCM middleware. To call the function, some
      drivers utilize hardware interrupt handlers, the others count handled PCM
      frames.
      
      Drivers for sound units on IEEE 1394 bus are the latter. They use two
      buffers; PCM buffer and DMA buffer for IEEE 1394 isochronous packet. PCM
      frames are copied between these two buffers and 'amdtp_stream' structure
      counts the handled PCM frames. Then, snd_pcm_period_elapsed() is called if
      required.
      
      Essentially, packet streaming layer should not be responsible for PCM
      frame processing. The PCM frame processing should be handled in each data
      block processing layer as a result of handling data blocks. Although, PCM
      frame counting is a common work for all of protocols which ALSA firewire
      stack is going to support.
      
      This commit adds two new helper functions as interfaces between packet
      streaming layer to data block processing layer. In future, each data block
      processing layer implements these functions. The packet streaming layer
      calls data block processing layer per packet by calling the functions. The
      data block processing layer processes data blocks and PCM frames, and
      returns the number of processed PCM frames. Then the packet streaming layer
      calculates handled PCM frames and calls snd_pcm_period_elapsed().

      ALSA: firewire-lib: add a member of frame_multiplier instead of double_pcm_frames · 6a4e89ff
      Takashi Sakamoto authored
      In future commit, interface between data block processing layer and packet
      stream processing layer is defined. These two layers communicate the
      number of data blocks and the number of PCM frames.
      
      The data block processing layer has a responsibility for calculating the
      number of PCM frames. Therefore, 'dual wire' of Dice quirk should be
      handled in data block processing layer.
      
      This commit adds a member of 'frame_multiplier'. This member represents
      the ratio of the number of PCM frames against the number of data blocks.
      Usually, the value of this member is 1, while it's 2 in Dice's 'dual wire'.

      ALSA: firewire-lib: add an argument for Dice's dual wire mode · 27ec83b5
      Takashi Sakamoto authored
      In IEC 61883-6, one data block represents one event. In ALSA, the event is
      one PCM frame. Therefore, when processing one data block, current
      implementation counts one PCM frame.
      
      On the other hand, Dice platform has a quirk called as 'dual wire' at
      higher sampling rate. In detail, see comment of commit 6eb6c81e
      ("ALSA: dice: Split stream functionality into a file").
      
      Currently, to handle this quirk, AMDTP stream structure has a
      'double_pcm_frames' member. When this is enabled, two PCM frames are
      counted. Each driver set this flag by accessing the structure member
      directly.
      
      In future commit, some members related to AM824 data block will be moved
      to specific structure, to separate packet streaming layer and data block
      processing layer. The access will be limited by opaque pointer.
      
      For this reason, this commit adds an argument into
      amdtp_stream_set_parameter() to set the flag.

      Currently, amdtp_stream_set_parameters() returns no error even if wrong
      arguments are given. This is not good for streaming layer because drivers
      can continue processing ignoring capability of streaming layer.

      Add GENERIC_PCI_IOMAP in the dependency list for VIA_RHINE as we are

      are not defined.

      David Hildenbrand authored
      We observed some performance degradation on s390x with dynamic
      halt polling. Until we can provide a proper fix, let's enable
      halt_poll_ns as default only for supported architectures.
      
      Architectures are now free to set their own halt_poll_ns
      default value.
