STRUCT SOF_IPC_FW_TRACING_OPS(9)

💖 struct sof_..._tracing_ops(9) 💖

okay bestie, welcome to the Kernel API Manual — this page is all about struct sof_ipc_fw_tracing_ops, aka the IPC-specific firmware tracing ops. no cap, it's giving "the function-pointer squad for tracing things." ✨

🌸 NAME 🌸

struct sof_ipc_fw_tracing_ops — IPC-specific firmware tracing ops. that's the name, that's the assignment. 💅

✨ SYNOPSIS ✨

struct sof_ipc_fw_tracing_ops {
    int (*init)(struct snd_sof_dev *sdev);
    void (*free)(struct snd_sof_dev *sdev);
    void (*fw_crashed)(struct snd_sof_dev *sdev);
    void (*suspend)(struct snd_sof_dev *sdev, pm_message_t pm_state);
    int (*resume)(struct snd_sof_dev *sdev);
 };

🎀 Members 🎀

• init — function pointer for initialization of the tracing. main character energy for setup. 💖
• free — optional function pointer for freeing of the tracing. optional, but iconic when present. 🎀
• fw_crashed — optional function pointer to notify the tracing of a firmware crash. yes, it's the "bestie, firmware said 💀" hook. 😭
• suspend — function pointer for system/runtime suspend. sleepy time vibes. 💤
• resume — function pointer for system/runtime resume. wake up bestie, we're back. 🌅
