STRUCT IOSM_CDEV(9)

💖 struct iosm_cdev(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's all about struct iosm_cdev, which is literally the state of the char driver layer 🎀. yes, the whole vibe of the char driver layer lives in one struct. iconic. let's get into it 🫶

🌸 NAME 🌸

struct iosm_cdev — state of the char driver layer, bestie. that's it, that's the whole thing 💅

⭐ SYNOPSIS ⭐

struct iosm_cdev {
    struct wwan_port *iosm_port;
    struct iosm_imem *ipc_imem;
    struct device *dev;
    struct iosm_pcie *pcie;
    enum wwan_port_type port_type;
    struct ipc_mem_channel *channel;
    enum ipc_channel_id chl_id;
 };

look at her. seven fields. main character energy fr fr 👑

🦋 Members 🦋

so here's the cast of this little struct, no cap:

• iosm_port — a pointer of type wwan_port, just vibing in there 💜
• ipc_imem — the imem instance 🧚
• dev — pointer to the device struct, keeping it grounded ✨
• pcie — the PCIe component, the hardware bestie 🌈
• port_type — the WWAN port type, aka the vibe check of the port 🔥
• channel — the channel instance 🍓
• chl_id — the Channel Identifier, so we know which channel iykyk 💀

lowkey reminder bestie: this page ships with the kernel source over at ./drivers/net/wwan/iosm, dated October 2026, and it's struct iosm_cdev(9) in the Kernel API Manual 🦋 mwah, go read the source, ily 💜✨
