  • ae891abe7   drm/i915: Split audio component to a generic type ... Browse Code »

    For allowing other drivers to use the DRM audio component, rename the
    i915_audio_component_* with drm_audio_component_*, and split the
    generic part into drm_audio_component.h. The i915 specific stuff
    remains in struct i915_audio_component, which contains
    drm_audio_component as the base.

    The license of drm_audio_component.h is kept to MIT as same as the the
    original i915_component.h.

    This is a preliminary change for further development, and no
    functional changes by this patch itself, merely code-split and
    renames.

    v1->v2: Use SPDX for drm_audio_component.h, fix remaining i915
    argument in drm_audio_component.h

  • 841b5ed7a   drm/i915/cnl: Add Port F definition. ... Browse Code »

    Some Cannonlake SKUs will come with a full split between
    port A and port E. This will be called port F although it
    is not a 6th port, but only a split.

    Note this patch alone is not sufficient for port F enabling,
    it's just the first step.

    v2: Fix size of dvo_ports found by Ander.
    v3: Adding missing cases from intel_bios.c for Port_F
    v4: Adding other missing cases and fix the commit message.
    v5: Rebase on top of display headers rework.
    v6 (from Paulo): improve commit message, bikeshed bit definitions.

  • f93189419   drm/i915/dp: DP audio API changes for MST ... Browse Code »

    DP MST provides the capability to send multiple video and audio streams
    through a single port. This requires the API's between i915 and audio
    drivers to distinguish between multiple audio capable displays that can be
    connected to a port. Currently only the port identity is shared in the
    APIs. This patch adds support for MST with an additional parameter
    'int pipe'. The existing parameter 'port' does not change it's meaning.

    pipe =
    MST : display pipe that the stream originates from
    Non-MST : -1

    Affected APIs:
    struct i915_audio_component_ops
    - int (*sync_audio_rate)(struct device *, int port, int rate);
    + int (*sync_audio_rate)(struct device *, int port, int pipe,
    + int rate);

    - int (*get_eld)(struct device *, int port, bool *enabled,
    - unsigned char *buf, int max_bytes);
    + int (*get_eld)(struct device *, int port, int pipe,
    + bool *enabled, unsigned char *buf, int max_bytes);

    struct i915_audio_component_audio_ops
    - void (*pin_eld_notify)(void *audio_ptr, int port);
    + void (*pin_eld_notify)(void *audio_ptr, int port, int pipe);

    This patch makes dummy changes in the audio drivers (thanks Libin) for
    build to succeed. The audio side drivers will send the right 'pipe' values
    for MST in patches that will follow.

    v2:
    Renamed the new API parameter from 'dev_id' to 'pipe'. (Jim, Ville)
    Included Asoc driver API compatibility changes from Jeeja.
    Added WARN_ON() for invalid pipe in get_saved_encoder(). (Takashi)
    Added comment for av_enc_map[] definition. (Takashi)

    v3:
    Fixed logic error introduced while renaming 'dev_id' as 'pipe' (Ville)
    Renamed get_saved_encoder() to get_saved_enc() to reduce line length

    v4:
    Rebased.
    Parameter check for pipe < -1 values in get_saved_enc() (Ville)
    Switched to for_each_pipe() in get_saved_enc() (Ville)
    Renamed 'pipe' to 'dev_id' in audio side code (Takashi)

    v5:
    Included a comment for the dev_id arg. (Libin)

  • 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.

    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,

  • 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.

    Register a component to be used to interface with the snd_hda_intel

    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)
