STRUCT DFL_FPGA_CDEV(9)

💖 NAME 💖

struct dfl_fpga_cdev — it's the container device for a DFL-based FPGA, bestie 💅

✨ SYNOPSIS ✨

struct dfl_fpga_cdev {
    struct device *parent;
    struct fpga_region *region;
    struct device *fme_dev;
    struct mutex lock;
    struct list_head port_dev_list;
    int released_port_num;
 };

🎀 Members 🎀

Okay so this struct is literally the mom friend of the group chat — here's everyone she's holding onto 🔥

• parent — the parent device of this container device, i.e. the one who brought her into this world 🫶
• region — the base fpga region. that's her home turf, no cap ✨
• fme_dev — the FME feature device hanging out under this container device 👑
• lock — a mutex lock whose whole job is protecting the port device list. she's the bouncer at the door, periodt 🔒
• port_dev_list — the list of all the port feature devices under this container device. the whole roster, fr fr 📋
• released_port_num — the released port number under this container device 💀
