STRUCT QNAP_MCU(9)

🌸 NAME 🌸

hey bestie, this is the manual page for struct qnap_mcu from the Kernel API Manual — section 9, no cap. 💅

struct qnap_mcu — QNAP NAS embedded controller. literally the whole vibe. ✨

✨ SYNOPSIS ✨

okay so here's the struct in all its glory — copy it exactly, bestie:

       struct qnap_mcu {
           struct serdev_device *serdev;
           struct mutex bus_lock;
           struct qnap_mcu_reply reply;
           const struct qnap_mcu_variant *variant;
           u8 version[QNAP_MCU_VERSION_LEN];
           u8 rx[QNAP_MCU_RX_BUFFER_SIZE];
        };

👑 Members 👑

• serdev — Pointer to underlying serdev. the connection bestie, iykyk. 🫶
• bus_lock — Lock to serialize access to the device. no cap, it keeps things from getting messy. 🔥
• reply — Reply data structure. the receipts, basically. 💌
• variant — Device variant specific information. every device has its own little lore. 🌈
• version — MCU firmware version. yes, the firmware version, periodt. ⭐
• rx — Receive buffer the reply is assembled in. where the reply gets built, literally. 🧚
