      ALSA: fireworks/firewire-lib: add support for recent firmware quirk · 18f5ed36
      Takashi Sakamoto authored
      Fireworks uses TSb43cb43c(IceLynx-Micro) as its IEC 61883-1/6 interface.
      This chip includes ARM7 core, and loads and runs program. The firmware
      is stored in on-board memory and loaded every powering-on from it.
      
      Echo Audio ships several versions of firmwares for each model. These
      firmwares have each quirk and the quirk changes a sequence of packets.
      
      As long as I investigated, AudioFire2/AudioFire4/AudioFirePre8 have a
      quirk to transfer a first packet with 0x02 in its dbc field. This causes
      ALSA Fireworks driver to detect discontinuity. In this case, firmware
      version 5.7.0, 5.7.3 and 5.8.0 are used.

      These models, AudioFire8 (since Jul 2009 ) and Gibson Robot Interface
      Pack series uses the same ARM binary as their firmware. Thus, this
      quirk may be observed among them.
      
      This commit adds a new member for AMDTP structure. This member represents
      the value of dbc field in a first AMDTP packet. Drivers can set it with
      a preferred value according to model's quirk.

      Revert "ALSA: fireworks: add support for AudioFire2 quirk" · c85523d1
      Takashi Sakamoto authored
      This reverts commit 9c6893e0.
      
      The fix is superseded by the next commit as a better implementation
      for supporting AudioFire2/AudioFire4/AudioFirePre8 quirks.

      As long as I investigated, firmware 5.7, 5.7.6 and 5.8 have this quirk.
      
      This commit adds a support for the quirk to handle AudioFire2 packets.
      For safe, CIP_SKIP_INIT_DBC_CHECK is applied to all versions of
      AudioFire2's firmwares.

      ALSA: fireworks/bebob/dice/oxfw: make it possible to shutdown safely · dec84316
      Takashi Sakamoto authored
      A part of these drivers, especially BeBoB driver, are programmed to wait
      some events. Thus the drivers should not destroy any data in .remove()
      context.
      
      This commit moves some destructors from 'struct fw_driver.remove()' to
      'struct snd_card.private_free()' to shutdown safely.

      ALSA: fireworks/bebob/dice/oxfw: allow stream destructor after releasing runtime · d23c2cc4
      Takashi Sakamoto authored
      Currently stream destructor in each driver has a problem to be called in
      a context in which sound card object is released, because the destructors
      call amdtp_stream_pcm_abort() and touch PCM runtime data.
      
      The PCM runtime data is destroyed in application's context with
      snd_pcm_close(), on the other hand PCM substream data is destroyed after
      sound card object is released, in most case after all of ALSA character
      devices are released. When PCM runtime is destroyed and PCM substream is
      remained, amdtp_stream_pcm_abort() touches PCM runtime data and causes
      Null-pointer-dereference.
      
      This commit changes stream destructors and allows each driver to call
      it after releasing runtime.

      ALSA: fireworks/bebob/dice/oxfw: add reference-counting for FireWire unit · 12ed7192
      Takashi Sakamoto authored
      Fireworks and Dice drivers try to touch instances of FireWire unit after
      sound card object is released, while references to the unit is decremented
      in .remove(). When unplugging during streaming, sound card object is
      released after .remove(), thus Fireworks and Dice drivers causes GPF or
      Null-pointer-dereferencing to application processes because an instance of
      FireWire unit was already released.
      
      This commit adds reference-counting for FireWire unit in drivers to allow
      them to touch an instance of FireWire unit after .remove(). In most case,
      any operations after .remove() may be failed safely.
