  • cae666ceb   drm/i915: Add get_eld audio component ... Browse Code »

    Implement a new i915_audio_component_ops, get_eld(). It's called by
    the audio driver to fetch the current audio status and ELD of the
    given HDMI/DP port. It returns the size of expected ELD bytes if it's
    valid, zero if no valid ELD is found, or a negative error code. The
    current state of audio on/off is stored in the given pointer, too.

    Note that the returned size isn't limited to the given max bytes. If
    the size is greater than the max bytes, it means that only a part of
    ELD has been copied back.

    For achieving this implementation, a new field audio_connector is
    added to struct intel_digital_port. It points to the connector
    assigned to the given digital port. It's set/reset at each audio
    enable/disable call in intel_audio.c, and protected with av_mutex.

  • f0675d4a8   drm/i915: Drop port_mst_index parameter from pin/eld callback ... Browse Code »

    The port_mst_index parameter was reserved for future use, but
    maintainers prefer to add it later when it is actually used.

    [Note: this is an update patch to commit [51e1d83cab99: drm/i915: Call
    audio pin/ELD notify function] where I mistakenly applied the older
    version. Jani and Daniel's review tags were to the latest version,
    so I add them below, too -- tiwai]

  • 2a8ceedf7   drm/i915: Add audio pin sense / ELD callback ... Browse Code »

    This callback will be called by the i915 driver to notify the hda
    driver that its HDMI information needs to be refreshed, i e,
    that audio output is now available (or unavailable) - usually as a
    result of a monitor being plugged in (or unplugged).

  • 632f3ab95   drm/i915/audio: add codec wakeup override enabled/disable callback ... Browse Code »

    Add support for enabling codec wakeup override signal to allow
    re-enumeration of the controller on SKL after resume from low power state.

    In SKL, HDMI/DP codec and PCH HD Audio Controller are in different power
    wells, so it's necessary to reset display audio codecs when power well on,
    otherwise display audio codecs will disappear when resume from low power
    state.
    Reset steps when power on:
    enable codec wakeup -> azx_init_chip() -> disable codec wakeup

    v3 by Jani: Simplify to only support toggling the appropriate chicken bit.

    v4 by Han: add explanation and specify the hw swquence.

  • 58fddc288   drm/i915: add component support ... Browse Code »

    Register a component to be used to interface with the snd_hda_intel
    driver. This is meant to replace the same interface that is currently
    based on module symbol lookup.

    v2:
    - change roles between the hda and i915 components (Daniel)
    - add the implementation to a new file (Jani)
    - use better namespacing (Jani)
    v3:
    - move the implementation to intel_audio.c (Daniel)
    - rename display_component to audio_component (Daniel)
    - add kerneldoc (Daniel)
    v4:
    - run forgotten git rm i915_component.c (Jani)
