ice_sq_done(9)

💖 NAME 💖

okay so bestie, this is the ice_sq_done(9) page from the Kernel API Manual ✨ and it’s literally about one job: poll until the last send on a control queue has completed. That’s the whole vibe. Periodt. 💅

🌸 SYNOPSIS 🌸

bool ice_sq_done (struct ice_hw *hw , struct ice_ctl_q_info *cq );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW struct 🫶
• cq — pointer to the specific Control queue 💖

🦋 DESCRIPTION 🦋

So the move here is: use read_poll_timeout to poll the control queue head, checking until it matches next_to_use 👀. According to the control queue designers, this has better timing reliability than the DD bit. No cap, that’s the flex. 💅

⭐ RETURN ⭐

true if all the descriptors on the send side of a control queue are finished processing, false otherwise. That’s it, bestie. ✅
