💅 ice_write_txq_ctx(9) — the one where we shove the Tx queue context into the hardware

okay so bestie, this is a page from the Kernel API Manual, section 9 (that's the kernel API section, iykyk). The star of the show is ice_write_txq_ctx, and honestly? She's a small function with main character energy. Let's get into it ✨

🌸 NAME

ice_write_txq_ctx — Write Tx queue context to HW

like, it literally writes the transmit queue context into the hardware. That's the whole vibe. No cap. 🎀

🦋 SYNOPSIS

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

look at her go. three arguments, returns an int, done. periodt. 💜

🍓 ARGUMENTS

  • hw — pointer to the hardware structure. this is the big one, she holds everything about the device 🫶
  • tlan_ctx — pointer to the Tx queue context. this is the actual info about the queue we're about to hand off 💖
  • txq_index — the index of the Tx queue. which queue are we talking about, bestie? this tells us 🌈

🧚 DESCRIPTION

So here's the tea ☕ — this function packs the Tx queue context into the dense HW layout, and then writes it into the HW registers.

That's two whole steps, okay? pack it up tight so it fits how the hardware wants it, then push it out to the registers. She's efficient. She's iconic. She gets it done 💅

🔥 RETURN

  • 0 on success — slay 🎉
  • -EINVAL if the Tx queue index is invalid — like, that index is not it, so she says no 🙈

👑 SEE ALSO

okay this list is LONG long, so buckle up bestie, we're going through the whole friend group. First up, the file where this all lives:

  • Kernel file ./drivers/net/ethernet/intel/ice/ice_common.c

and now the extended squad, in the exact order they showed up:

like I said. LONG list. she knows everybody 💀

ngl if you're reading this page you probably already live in ./drivers/net/ethernet/intel/ice, and honestly? respect. 🫶

and that's the page, bestie! this one ships out of ./drivers/net/ethernet/intel/ice, October 2026 edition — mwah, go read the rest of the 9-section lore, ily 💖✨🌈
