tw68_risc_field(9)

💜 tw68_risc_field(9) — from the Kernel API Manual, bestie

Okay so real talk, this one's a little deep-cut from the kernel: tw68_risc_field(9). It lives in section 9 (kernel API, for the devs 🫶) and it's the helper that builds RISC program bits for a tw68 video capture field. No cap, it's a whole vibe.

✨ NAME ✨

tw68_risc_field — literally the function name and that's it. The description slot is empty in the source docs, so I'm not gonna make up lore for you 💀. Just know the name, know the game.

🌸 SYNOPSIS 🌸

__le32 * tw68_risc_field (__le32 *rp , struct scatterlist *sglist ,
       unsigned int offset , u32 sync_line , unsigned int bpl , unsigned int
       padding , unsigned int lines , bool jump );

She returns an __le32 * and takes eight args. Iconic signature, tbh. 🎀

🦋 ARGUMENTS 🦋

• rp — pointer to the current risc program position. This is where we're writing, bestie. 📍
• sglist — pointer to the "scatter-gather list" of buffer pointers. Yes, with the quotes, that's the actual wording. It's giving buffer-pointer buffet. 🍓
• offset — offset to the target memory buffer. Where the party actually starts. ✨
• sync_line — 0 -> no sync, 1 -> odd sync, 2 -> even sync. Three modes, pick your fighter. 🌈
• bpl — number of bytes per scan line. Bytes! Per line! ⭐
• padding — number of bytes of padding to add. Gotta have the padding, it's the eyeliner of memory layout 💅
• lines — number of lines in the field. Count 'em. 🔥
• jump — insert a jump at the start. Yes queen, go straight to jump 🧚

👑 SEE ALSO 👑

• Kernel file ./drivers/media/pci/tw68/tw68-risc.c — the actual source, go read it, iykyk 📖
• tw68_risc_buffer(9) — her sibling function, also slaying in section 9 💖

Heads up bestie: that sync_line value is a tiny enum in disguise — 0, 1, 2 only. Don't be out here freelancing with 3. 🙈

That's the whole page, and honestly? She ate. ✨ This cutie came out of the ./drivers/media/pci/tw68 source tree and is dated October 2026 — catch you in the kernel docs, bestie, mwah 🫶💜🎀
