fifo_icap_reset(9)

✨ fifo_icap_reset(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's a little function from the Xilinx HWICAP corner of the kernel and honestly? it's giving "one job, does it well" 💅

---

🌸 NAME 🌸

fifo_icap_reset — resets the logic of the icap device. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

void fifo_icap_reset (struct hwicap_drvdata *drvdata );

no return value, no drama, just vibes 🔥

---

💖 ARGUMENTS 💖

• drvdata — a pointer to the drvdata. yes queen, hand over the pointer and let her cook 🫶

---

⭐ DESCRIPTION ⭐

so what does she actually do? this function forces the software reset of the complete HWICAP device, no cap 😭

like, full send. as a result of this software reset:

• all the registers go right back to their default value (factory settings era, we love a fresh start ✨)
• the FIFO gets flushed too — part of the package deal, not an optional extra 💅

so basically one call and the whole device is hitting the reset button and starting a new chapter 🌈
