STRUCT PM8XXX_VIB(9)

💅 struct pm8xxx_vib(9) — the Kernel API Manual moment

okay so bestie, welcome to the <pink>kernel API manual</pink> for struct pm8xxx_vib, which is genuinely just… the structure to hold vibrator data 🎀 that's the whole vibe. literally the little home where your vibrator's info lives. no cap.

✨ SYNOPSIS ✨

struct pm8xxx_vib {
    struct input_dev *vib_input_dev;
    struct work_struct work;
    struct regmap *regmap;
    const struct pm8xxx_regs *regs;
    unsigned int enable_addr;
    unsigned int drv_addr;
    unsigned int drv2_addr;
    int speed;
    int level;
    bool active;
    u8 reg_vib_drv;
 };

look at her. eleven fields. main character energy, honestly 👑 and every single one matters, so let's go through them one by one, no skipping 💖

🌸 Members 🌸

• vib_input_dev — the input device that supports force feedback. this is the one that actually brings the haptics, the rumble, the whole moment ✨
• work — a work structure, and its entire job is to set the vibration parameters. it's giving backstage crew energy, doing the work so the vibes can happen 🫶
• regmap — the regmap for register read/write. yes you read (and write) that correctly 💅
• regs — the registers' info. all the little register details live here 📋
• enable_addr — the vibrator enable register. the on switch, basically. the yes address 💚
• drv_addr — the vibrator drive strength register. how hard we're going, address edition 🔥
• drv2_addr — the vibrator drive strength upper byte register. that's the upper byte specifically, don't forget the upper byte bestie 😭
• speed — speed of vibration set from userland. userland gets to pick how fast, iconic ⚡
• level — level of vibration to set in the chip. this one's set in the chip, not userland, important distinction 🎀
• active — the state of the vibrator. it's a bool. on or off. that's it. vibe check passed 🦋
• reg_vib_drv — the regs->drv_addr register value. it's a u8, and yes it's literally holding that register's value 💜
