STRUCT FWCTL_INFO_MLX5(9)

✨ struct fwctl_info_mlx5(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9 — today's main character is struct fwctl_info_mlx5, and honestly? she's lowkey iconic 💅

---

🌸 NAME 🌸

struct fwctl_info_mlx5 — the struct you get back as out_device_data from ioctl(FWCTL_INFO) 🎀

---

🦋 SYNOPSIS 🦋

the whole vibe, verbatim:

struct fwctl_info_mlx5 {
    __u32 uid;
    __u32 uctx_caps;
 };

---

👑 Members 👑

• uid — the FW UID this FD is bound to. and like, it's not optional bestie: every single command header will force this value. no cap, it's giving "the rules are the rules" 🫶
• uctx_caps — the FW capabilities that are enabled for the uid. that's the tea ☕

---

💖 Description 💖

returns the basic intel about the FW interface you've got available — literally just the lowdown, nothing extra, and that's on periodt ✨

---

🧚 SEE ALSO 🧚

• Kernel file ./include/uapi/fwctl/mlx5.h — go read it, iykyk 📖

ngl this page is short and sweet, so if you blinked you missed it. go forth and slay your ioctl(FWCTL_INFO) calls 💜
