ice_get_sw_fv_bitmap(9)

💅 ice_get_sw_fv_bitmap(9) — like, the Kernel API Manual entry, bestie ✨

Okay so this is a page from the Kernel API Manual (manual section 9, the one for kernel routines, iykyk) and it's all about ice_get_sw_fv_bitmap — the way that this function goes and grabs you a switch field vector bitmap based on what profile type you asked for. It's giving "little helper that knows where all the field vectors live" energy. 🦋

🌸 NAME 🌸

ice_get_sw_fv_bitmap — no cap, this is the one that gets the switch field vector bitmap based on profile type. That's literally the whole job. 💖

---

✨ SYNOPSIS ✨

void ice_get_sw_fv_bitmap (struct ice_hw *hw , enum ice_prof_type
req_profs , unsigned long *bm );

Notice the return type? Yeah, void. It doesn't hand anything back to you — it fills in the bitmap you point it at. Main character behaviour tbh. 👑

---

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure. Like, the actual hardware vibes. You gotta hand it over. 🫶
• req_profs — type of profiles requested. This is you telling it which flavour of profiles you're after.
• bm — pointer to memory for returning the bitmap of field vectors. You provide the memory, it provides the bits. Teamwork, periodt. 💅

That's the whole page, bestie — no hidden sections, no secret flags, nothing to memorise past the three arguments. Go forth and get those field vector bitmaps. 🧚‍♀️

And that's a wrap! 🍓 This gem lives over in ./drivers/net/ethernet/intel/ice and it's dated October 2026 — so yeah, it's giving future-iconic. Bye bestie, slay your kernel work 💜🔥
