STRUCT DFL_FPGA_PORT_OPS(9)

🎀 NAME 🎀

okay so this is struct dfl_fpga_port_ops — literally just "port ops", that's the whole vibe. it's a struct from the dfl_fpga_port_ops(9) page in the Kernel API Manual, and bestie, it's giving "small struct, big responsibilities" 💅

---

✨ SYNOPSIS ✨

here's the whole thing, exactly as it lives, no cap:

struct dfl_fpga_port_ops {
    const char *name;
    struct module *owner;
    struct list_head node;
    int (*get_id)(struct dfl_feature_dev_data *fdata);
    int (*enable_set)(struct dfl_feature_dev_data *fdata, bool enable);
 };

like, five members, all mains, no filler. we love to see it 🫶

🌸 Members 🌸

okay let's meet the cast, one by one:

• name — the name of this port ops 🏷️ it's the thing that gets matched up with the port platform device, so pick a good one, iykyk.
• owner — a pointer to the module that owns this port ops. like, whose name is on the lease, fr fr.
• node — the node that links port ops into the global list 🔗 it's the little connector that keeps everybody in the group chat.
• get_id — gets the port id straight from the hardware. hardware knows, hardware tells 🔥
• enable_set — enables or disables the port, on and off, slay 💅

💜 SEE ALSO 💜

if you're gonna go read more (and you should, bestie, it's a whole ecosystem), start with the kernel file ./drivers/fpga/dfl.h and then go meet the whole friend group:

• struct dfl_feature_id(9)
• struct dfl_feature_driver(9)
• struct dfl_feature_irq_ctx(9)
• struct dfl_feature(9)
• struct dfl_feature_dev_data(9)

• struct dfl_fpga_enum_info(9)
• struct dfl_fpga_enum_dfl(9)
• struct dfl_fpga_cdev(9)

ok that's the whole page 🌈 no options to memorise, no scary defaults, just a struct and its five iconic members. you ate that, honestly.

and that's a wrap, bestie! 🦋 this one comes to you from ./drivers/fpga, stamped October 2026 — go forth and port-ops responsibly ✨💖
