ice_vsig_alloc(9)

💅 ice_vsig_alloc(9) — the VSIG scavenger hunt, but make it kernel

okay so bestie, welcome to the ice_vsig_alloc page from the Kernel API Manual ✨ this one's short and sweet and honestly kind of iconic in its simplicity — no cap, it does exactly one (1) thing and it does it well 🫶

---

🎀 NAME 🎀

ice_vsig_alloc — finds a free entry and allocates a new VSIG 💖

like, literally that's the whole personality. it goes looking for a free slot, claims it, and hands it back to you. main character energy but make it a lookup table 🔥

---

🦋 SYNOPSIS 🦋

u16 ice_vsig_alloc (struct ice_hw *hw , enum ice_block blk );

that's it, that's the signature 👑 it returns a u16 and takes two args, both listed below, don't skip them bestie 🙈

---

🌸 ARGUMENTS 🌸

• hw — pointer to the hardware structure 💜 this is your hardware context, the whole vibe check of the device lives in here
• blk — HW block ⭐ it's an enum ice_block, so tell it which block you're working with and it'll handle the rest

---

✨ DESCRIPTION ✨

okay so here's the tea 🍓 this function will iterate through the VSIG list and mark the first unused entry for the new VSIG entry as used and return that value.

that's it!! it walks the list, spots the first free slot, flips it to used, and gives you back the value. lowkey efficient, highkey satisfying 💅 no searching for the best slot, no sorting, no drama — first free one wins, periodt 💀

ngl it's giving "first available seat in the library" and honestly we respect the consistency 🧚

heads up bestie 💀 this page gives you the what but not the what if it fails — no error codes or return-value caveats listed in the original, so don't come for me, I'm just the messenger 🙈
