STRUCT PECI_CONTROLLER(9)

💖 struct peci_controller: PECI controller 💖

okay bestie, welcome to the struct peci_controller(9) page from the Kernel API Manual ✨ this is the struct that represents a PECI controller, and we’re gonna walk through it together, no cap 🫶

🌸 NAME 🌸

struct peci_controller — PECI controller 💅

✨ SYNOPSIS ✨

       struct peci_controller {
           struct device dev;
           const struct peci_controller_ops *ops;
           struct mutex bus_lock;
           u8 id;
        };

🎀 Members 🎀

• dev — device object to register PECI controller to the device model. literally the device-model hookup, iykyk 💖
• ops — pointer to device specific controller operations. this is where the controller-specific moves live ✨
• bus_lock — lock used to protect multiple callers. keep those callers from stepping on each other’s toes, periodt 🔒
• id — PECI controller ID. the controller’s little name tag 🏷️

🌈 Description 🌈

PECI controllers usually connect to their drivers using non-PECI bus, such as the platform bus. Each PECI controller can communicate with one or more PECI devices 🦋
