  • b04479fb8   ALSA: firewire-lib: Add a new function to check others' connection ... Browse Code »

    Plug Control Registers have two fields related to the number of established
    connections, one is 'Broadcast connection counter' and another is
    'Point-to-point connection counter'. The driver can know there are established
    connections or not to check these fields.

    This commit is for considering about JACK/FFADO streaming. Currently, when
    JACK/FFADO starts its streaming to the device, cmp_connection_establish() is
    failed expectedly. This seems to be enough but there are some devices which
    needs to change sampling frequency before trying to establish connections.
    For such devices, this functionality is needed.

  • c68a1c658   ALSA: firewire-lib: Add 'direction' member to 'cmp_connection' structure ... Browse Code »

    This patch adds 'direction' member to 'cmp_connection' structure to indicate
    the direction of connection. This patch also adds 'direction' argument to
    cmp_connection_init() function to determine the direction.

    The cmp_connection_init() function is exported and used in snd-firewire-speakers
    so this patch also affect it.

    This patch just add them. Actual implementation will be done by followed
    patches.

  • a7fa0d047   ALSA: firewire-lib: Rename macros, variables and functions for CMP ... Browse Code »

    Referring to IEC 61883-1, oMPR and iMPR, oPCR and iPCR have some fields with
    the same role in the same position. This patch renames some macros, variables
    and function arguments with "i" in its prefix to reuse them between oMPR and
    iMPR, oPCR and iPCR.

  • 31ef9134e   ALSA: add LaCie FireWire Speakers/Griffin FireWave Surround driver ... Browse Code »

    Add a driver for two playback-only FireWire devices based on the OXFW970
    chip.

    v2: better AMDTP API abstraction; fix fw_unit leak; small fixes
    v3: cache the iPCR value
    v4: FireWave constraints; fix fw_device reference counting;
    fix PCR caching; small changes and fixes
    v5: volume/mute support; fix crashing due to pcm stop races
    v6: fix build; one-channel volume for LaCie
    v7: use signed values to make volume (range checks) work; fix function
    block IDs for volume/mute; always use channel 0 for LaCie volume
