omap_prefetch_enable(9)

✨ omap_prefetch_enable(9) ✨

okay bestie, welcome to the Kernel API Manual — yes, the whole manual, and today's main character is omap_prefetch_enable. This little icon is literally the one that configures and starts prefetch transfer 🎀 that's the whole NAME vibe, periodt.

🌸 SYNOPSIS 🌸

int omap_prefetch_enable (int cs , int fifo_th , int dma_mode , unsigned
int u32_count , int is_write , struct omap_nand_info *info );

like… look at her. six arguments. she's booked and busy 💅

🦋 ARGUMENTS 🦋

• cs — the cs (chip select) number. which chip we're talking to, bestie 🫶
• fifo_th — the fifo threshold to be used for read/ write. yes, read and write, she serves both 💖
• dma_mode — dma mode enable (1) or disable (0). one or zero, no in-between, no cap ⭐
• u32_count — number of bytes to be transferred. the actual amount of stuff moving, fr fr 🌈
• is_write — prefetch read(0) or write post(1) mode. so 0 = read, 1 = write post, iykyk 💜
• info — NAND device structure containing platform data. that's a struct omap_nand_info *, and it's giving main character energy 👑

like, that's a whole squad 😭🔥 every single one of them, no skips, we don't do skipping here 💀

ngl, that's the entire page — no DESCRIPTION, no OPTIONS, no exit statuses, just the NAME, the SYNOPSIS, the ARGUMENTS and the SEE ALSO. short and iconic. ate and left no crumbs 🍓💅

and that's a wrap, bestie! this cutie lives under ./drivers/mtd/nand/raw in the Kernel API Manual, dated October 2026 — mwah, go read the source, ily 🫶💖✨
