STRUCT IPACK_BUS_OPS(9)

✨ struct ipack_bus_ops(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct ipack_bus_ops — literally the whole personality of a bridge module, like all the operations it can actually do 🎀 no cap.

💖 NAME 💖

struct ipack_bus_ops — available operations on a bridge module ✨

🦋 SYNOPSIS 🦋

struct ipack_bus_ops {
    int (*request_irq) (struct ipack_device *dev, irqreturn_t
(*handler)(void *), void *arg);
    int (*free_irq) (struct ipack_device *dev);
    int (*get_clockrate) (struct ipack_device *dev);
    int (*set_clockrate) (struct ipack_device *dev, int mherz);
    int (*get_error) (struct ipack_device *dev);
    int (*get_timeout) (struct ipack_device *dev);
    int (*reset_timeout) (struct ipack_device *dev);
 };

like look at her, she's giving function-pointer buffet 💅 every single member is a little callback waiting to be called.

🌸 Members 🌸

• request_irq — request IRQ 🫶 that's it, that's the whole job, she requests the IRQ.
• free_irq — free IRQ 💀 the matching clean-up arc, iconic duo behavior.
• get_clockrate — returns the clockrate the carrier is currently communicating with the device at ⏰✨
• set_clockrate — sets the clock-rate for carrier / module communication. Should return -EINVAL if the requested speed is not supported 🙈 like if you ask for a speed she can't do, she's gonna hit you with that -EINVAL, periodt.
• get_error — returns the error state for the slot the device is attached to 💔 lowkey the vibe check of the slot.
• get_timeout — returns 1 if the communication with the device has previously timed out ⏳ yes literally 1, not 0/-1 chaos, just 1.
• reset_timeout — resets the state returned by get_timeout 🔄 fresh start energy, we love a reset.
