ice_read_txq_ctx(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to ice_read_txq_ctx(9) from the Kernel API Manual — manual name folded in near the top, header line not copied, we move 💅 this page is literally about reading a Tx queue context out of the HW and unpacking it, and the vibes are immaculate.

✨ NAME ✨

ice_read_txq_ctx — read Tx queue context from HW. that's the name, that's the mission, periodt 🎀

🦋 SYNOPSIS 🦋

int ice_read_txq_ctx (struct ice_hw *hw , struct ice_tlan_ctx *tlan_ctx
, u32 txq_index );

🎀 ARGUMENTS 🎀

okay so here's the tea, bestie:

  • hw — pointer to the hardware structure. that's the hardware one, the big important pointer 🫶
  • tlan_ctx — pointer to the Tx queue context. this is where the unpacked context goes ✨
  • txq_index — the index of the Tx queue. you gotta tell it which queue you're reading, obviously 💅

🌸 DESCRIPTION 🌸

Read the Tx queue context from the HW registers, then unpack it into the ice_tlan_ctx structure for use. that's literally it, no cap. this function pulls the Tx queue context out of the HW registers and unpacks it into the ice_tlan_ctx structure so it's ready to use. it's giving hardware whisperer energy 🔥

🔥 RETURN 🔥

returns 0 on success, or -EINVAL on an invalid Tx queue index. so if the index is bad, it's -EINVAL; if everything is good, it's 0. periodt 💖
