idpf_tx_singleq_map(9)

💅 NAME 💅

okay so this is the Kernel API Manual page for idpf_tx_singleq_map(9), and it's literally the function that builds the Tx base descriptor, bestie. no cap.

idpf_tx_singleq_map — Build the Tx base descriptor ✨

✨ SYNOPSIS ✨

void idpf_tx_singleq_map (struct idpf_tx_queue *tx_q , struct idpf_tx_buf *first , struct idpf_tx_offload_params *offloads );

🎀 ARGUMENTS 🎀

• tx_q — the queue you're sending the buffer on, icon.
• first — the first buffer info buffer to use, iykyk.
• offloads — pointer to the struct that holds offload parameters 🫶

🦋 DESCRIPTION 🦋

so the vibe here is: this function loops over the skb data pointed to by *first, gets a physical address for each memory location, and programs that address plus the length into the transmit base mode descriptor. periodt 💅

like, it's giving “walk the skb data and set up the Tx descriptor,” and that's exactly what it does. no extra lore, no side quests.
