✨ mips_ejtag_fdc_handle(9) ✨

okay so this is a page straight out of the Kernel API Manual (yes, the whole manual, and yes this little function is in it 💅). it's like the group chat of kernel docs and you've been added to it, bestie. let's get into it 🫶

---

🌸 NAME 🌸

mips_ejtag_fdc_handle — handle FDC events, periodt.

---

🎀 SYNOPSIS 🎀

void mips_ejtag_fdc_handle (struct mips_ejtag_fdc_tty *priv );

that's it. one function, one argument, void return, no chaos. iconic.

---

🦋 ARGUMENTS 🦋

• priv — pointer to the driver's private data. it's the driver's own little bag of stuff, and you're handing it over so the function can do its thing. no cap, that's the whole argument ✨

---

💖 DESCRIPTION 💖

so what does it actually do? it handles FDC events, fr fr. and there are two whole vibes of event happening here:

• new incoming data is showing up and needs to be drained out of the RX FIFO and fed into the appropriate TTY ports. the way that data just sits there waiting to be scooped out 😭🍓
• space is becoming available in the TX FIFO, which would allow more data to be written out. like when the queue finally breathes and you're like "omg there's room, we can send more" 🔥

that's the assignment. keeping the data flowing in both directions and making sure nothing just sits there gathering dust. main character energy for a helper function, honestly 👑

ngl this is the plumbing underneath your serial console situation — if data's moving, somebody's calling this. respect the process 🫡

🌟 cute little sign-off 🌟

this gem lives in ./drivers/tty, and the docs are dated October 2026 — so go forth, handle those FDC events, and remember: drain your RX FIFO, respect your TX FIFO, and stay slay 💅✨🎀🦋🌸💖
