💅 wx_alloc_q_vector — Allocate memory for a single interrupt vector 💅

okay so real talk bestie, this is a page straight out of the Kernel API Manual, section 9 of the manuals, and the star of the show is wx_alloc_q_vector(9). It's giving "one job, one vector, let's go" energy and honestly? Iconic. 🎀

✨ NAME ✨

wx_alloc_q_vector — Allocate memory for a single interrupt vector 💜

🌸 SYNOPSIS 🌸

int wx_alloc_q_vector (struct wx *wx , unsigned int v_count , unsigned
int v_idx , unsigned int txr_count , unsigned int txr_idx , unsigned int
rxr_count , unsigned int rxr_idx );

🦋 ARGUMENTS 🦋

Every single one of these babies, no skips, no cap:

  • wx — the board private structure you're initializing 🫶
  • v_count — the q_vectors allocated on wx, used for ring interleaving 👑
  • v_idx — the index of the vector in the wx struct ⭐
  • txr_count — total number of Tx rings to allocate 🔥
  • txr_idx — index of the first Tx ring to allocate 🌈
  • rxr_count — total number of Rx rings to allocate 🍓
  • rxr_idx — index of the first Rx ring to allocate 🧚

💖 DESCRIPTION 💖

We allocate one q_vector. That's it. That's the whole vibe. 💅

And if that allocation fails? We return -ENOMEM. Not me crying in errno 😭 — that's literally the documented behaviour, so plan for it bestie.

okay that's the whole page, go slay 🫶✨ bye bestie, ily, read your errno values 💖
