mlx5_fpga_get_sbu_caps(9)

💅 mlx5_fpga_get_sbu_caps(9) — the Kernel API Manual page, but make it make sense

okay so bestie, this is a page from the Kernel API Manual and the whole entire star of the show is mlx5_fpga_get_sbu_caps(9) 💖 she reads the SBU capabilities, and honestly? iconic behavior.

---

✨ NAME ✨

mlx5_fpga_get_sbu_caps — Read the SBU capabilities 🎀

---

🦋 SYNOPSIS 🦋

int mlx5_fpga_get_sbu_caps (struct mlx5_fpga_device *fdev , int size ,
       void *buf );

three args, no drama. keep it exactly like that, char for char, fr fr 🌸

---

💜 ARGUMENTS 💜

• fdev — the FPGA device. like, the actual device you're doing the thing to 🫶
• size — the size of the buffer you're reading into. important, do not skip, iykyk
• buf — the buffer the capabilities get read into ✨

---

🔥 DESCRIPTION 🔥

so what she does is: reads the FPGA SBU capabilities into the specified buffer. that's the whole vibe 💅

and the format of that capabilities buffer? SBU-dependent. meaning it depends on the SBU — not us, not you, not the kernel, the SBU. so don't come for me asking what it looks like, nobody promised you a struct here 😭

---

🌈 RETURN 🌈

• 0 — if successful. slay ✅
• -EINVAL — if the buffer is not large enough to contain SBU caps 🚫
• any other error value — otherwise, i.e. literally anything else that goes wrong 💀
