💅 create_sg_component(9) — Kernel API Manual 💅

✨ NAME ✨

Okay so create_sg_component is the function that creates SG componets for the N5 device. That's the vibe. 💖

🌸 SYNOPSIS 🌸

int create_sg_component (struct nitrox_softreq *sr , struct
       nitrox_sgtable *sgtbl , int map_nents );

🎀 ARGUMENTS 🎀

• sr — Request structure. Like the request's main character. 💅
• sgtbl — SG table. The table doing SG things. 🦋
• map_nents — number of dma mapped entries. Literally the count, bestie. ✨

🦋 DESCRIPTION 🦋

Component structure. Not me staring at the ASCII art, but here it is exactly as the manual hands it to us:

       Component structure
