ice_sq_send_cmd(9)

💖 ice_sq_send_cmd — the kernel API manual, bestie edition 🎀

okay so this is ice_sq_send_cmd(9) from the Kernel API Manual, and it's literally the main character of the transmit side of a control queue. stay with me, you're gonna slay this 💅

---

✨ NAME ✨

ice_sq_send_cmd — send command to a control queue 🦋

---

✨ SYNOPSIS ✨

int ice_sq_send_cmd (struct ice_hw *hw , struct ice_ctl_q_info *cq ,
struct libie_aq_desc *desc , void *buf , u16 buf_size , struct ice_sq_cd
*cd );

---

✨ ARGUMENTS ✨

• hw — pointer to the HW struct. the hardware vibes, essential, no cap 🫶
• cq — pointer to the specific Control queue. like, which queue, be specific bestie 🌸
• desc — a prefilled descriptor describing the command. you do the filling before you call, okay? it's already dressed, you're just sending it out 💅
• buf — buffer to use for indirect commands (or NULL for direct commands). yes, NULL is valid here, that's the direct-command life 💀
• buf_size — size of buffer for indirect commands (or 0 for direct commands). pair it up with buf, they're a matching set 🎀
• cd — pointer to command details structure 👑

---

✨ DESCRIPTION ✨

Main command for the transmit side of a control queue. literally the icon, the moment 🔥

Here's the whole glow-up it does for you:

1. it puts the command on the queue 📥
2. it bumps the tail 🚀
3. it waits for processing of the command ⏳ (yes, actual waiting, be patient)
4. it captures command status and results 📸
5. etc. ✨

so yeah. it's the "send the thing and stick around to see what happened" function. very responsible of it, honestly 🧚
