meson_spifc_txrx(9)

✨ meson_spifc_txrx ✨

okay so bestie, welcome to the meson_spifc_txrx page — it's a kernel API manual situation, section 9 ofc, and honestly it's giving "one job, done cute." 🎀

This is a function that literally transfers a chunk of data. That's it, that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

int meson_spifc_txrx (struct meson_spifc *spifc , struct spi_transfer
*xfer , int offset , int len , bool last_xfer , bool last_chunk );

the way it returns an int… we love a return value that tells us how it went 🫶

---

💖 ARGUMENTS 💖

• spifc — the Meson SPI device itself, the main character of this whole operation 👑
• xfer — the current SPI transfer, aka the thing we're working on rn
• offset — where in the data we're starting, the offset bestie, the "skip to here" energy
• len — length of the data to transfer, so we know how much to actually move ✨
• last_xfer — bool that says whether this is the last transfer of the message (the finale 🎬)
• last_chunk — bool that says whether this is the last chunk of the transfer, so like… the final little piece 🍓

---

🔥 RETURN 🔥

• 0 on success — slay, we ate 💅
• a negative value on error — not the vibe, but at least it tells you 😭

ngl this page is short but it's iconic — every argument, every return value, no cap, all here 💀

and that's the wrap bestie!! this one came out of ./drivers/spi, dated October 2026, and it's proudly meson_spifc_txrx(9) — go forth and transfer your chunks responsibly 🫶✨💜
