STRUCT SOF_IPC_TPLG_OPS(9)

✨ struct sof_ipc_tplg_ops(9) ✨

okay bestie, so this is the kernel API manual for struct sof_ipc_tplg_ops — it's literally the IPC-specific topology ops struct and it's giving main character energy in the SOF audio world 💅

🎀 SYNOPSIS 🎀

struct sof_ipc_tplg_ops {
    const struct sof_ipc_tplg_widget_ops *widget;
    const struct sof_ipc_tplg_control_ops *control;
    int (*route_setup)(struct snd_sof_dev *sdev, struct snd_sof_route *sroute);
    int (*route_free)(struct snd_sof_dev *sdev, struct snd_sof_route *sroute);
    const struct sof_token_info *token_list;
    int (*control_setup)(struct snd_sof_dev *sdev, struct snd_sof_control *scontrol);
    int (*control_free)(struct snd_sof_dev *sdev, struct snd_sof_control *scontrol);
    int (*pipeline_complete)(struct snd_sof_dev *sdev, struct snd_sof_widget *swidget);
    int (*widget_setup)(struct snd_sof_dev *sdev, struct snd_sof_widget *swidget);
    int (*widget_free)(struct snd_sof_dev *sdev, struct snd_sof_widget *swidget);
    int (*dai_config)(struct snd_sof_dev *sdev, struct snd_sof_widget *swidget, unsigned int flags, struct snd_sof_dai_config_data *data);

    int (*dai_get_param)(struct snd_sof_dev *sdev, struct snd_sof_dai *dai, int param_type);
    int (*set_up_all_pipelines)(struct snd_sof_dev *sdev, bool verify);
    int (*tear_down_all_pipelines)(struct snd_sof_dev *sdev, bool verify);

🌸 Members 🌸

okay so let's break down every single one of these, no skipping, we're doing the full tour 🫶

• widget — array of pointers to IPC-specific ops for widgets, and it's lowkey important that this should always be of size SND_SOF_DAPM_TYPE_COUNT — like, one per widget type, periodt. unsupported widget types get initialized to 0 ✨
• control — pointer to the IPC-specific ops for topology kcontrol IO, iconic behavior honestly 💅
• route_setup — function pointer for setting up pipeline connections 🔥
• route_free — function pointer for freeing pipeline connections, the cleanup crew fr fr
• token_list — list of all tokens supported by the IPC version. the size of the token_list array should be SOF_TOKEN_COUNT, and any unused elements in the array get initialized to 0 — no cap 💀
• control_setup — function pointer for setting up kcontrol IPC-specific data, it's giving preparation queen energy 👑
• control_free — function pointer for freeing kcontrol IPC-specific data, release the data bestie 🦋
• pipeline_complete — function pointer for pipeline complete IPC, we love a finished pipeline moment ⭐
• widget_setup — function pointer for setting up setup in the DSP, yes it literally says "setting up setup" and we're not questioning it, just vibing 😭
• widget_free — function pointer for freeing widget in the DSP, goodbye widget, you served 💖
• dai_config — function pointer for sending DAI config IPC to the DSP, talk to 'em 📢
• host_config — function pointer for setting the DMA ID for host widgets, very demure, very mindful 🌸
• dai_get_param — function pointer for getting the DAI parameter, go get that info ✨
• set_up_all_pipelines — function pointer for setting up all topology pipelines, ALL of them, not just some, bestie 💅
• tear_down_all_pipelines — function pointer for tearing down all topology pipelines, dramatic exit energy 💀
• parse_manifest — function pointer for ipc4 specific parsing of topology manifest, ipc4 said "I'll handle this one" 🌈
• link_setup — function pointer for IPC-specific DAI link set up, link it up 🔗

💜 Note 💜

okay so this is important — the function pointers (ops) are optional. not required. they're like, the accessories of the struct. wear them if you want to 💅✨

okay that's the whole struct, every single member accounted for, we ate and left no crumbs 👑 periodt 🎀
