STRUCT ISSEI_DMA_LENGTH(9)

💖 struct issei_dma_length(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual, and it's genuinely such a small slay. Like, it's literally just a struct that holds sizes of DMA memory portions. That's the whole vibe. No cap. 🎀

✨ NAME ✨

struct issei_dma_length — sizes of DMA memory portions 🦋

✨ SYNOPSIS ✨

struct issei_dma_length {
    size_t h2f;
    size_t f2h;
    size_t ctl;
 };

like… look at her. three size_ts. main character energy fr fr. 💅

🌸 Members 🌸

• h2f — the host to firmware buffer size 🫶 (yes, "h to f", she's named after the journey)
• f2h — the firmware to host buffer size 💜 (the return trip, iconic)
• ctl — the control buffer size ⭐ (the little boss of the operation)

🌈 SEE ALSO 🌈

• Kernel file ./drivers/misc/issei/dma.h — go read it, iykyk 📖
• struct issei_dma(9) 👑
• struct issei_dma_data(9) 🔥

ngl bestie, this one's short and sweet — but every field counts, so don't sleep on ctl okay? 🙈

so yeah, that's the whole page. no bugs to warn you about, no exit codes, no env vars — just three sizes chillin' in a struct. obsessed. 💖✨🌸

and for the cute sign-off: this lil beauty lives in ./drivers/misc/issei and it's dated October 2026 — see you there, bestie 🧚💜
