mmc_interrupt_hpi(9)

💅 mmc_interrupt_hpi — a kernel API manual, bestie edition ✨

okay so real quick, before anything else: the manual name is mmc_interrupt_hpi(9) and you're gonna want to remember it, because this little function is the one that yells "EXCUSE ME, PRIORITY!" at an MMC card mid-operation. 🎀

🌸 NAME 🌸

mmc_interrupt_hpi — Issue for High priority Interrupt

like, that's literally the whole vibe: it issues the High Priority Interrupt. no cap. ✨

---

🦋 SYNOPSIS 🦋

int mmc_interrupt_hpi (struct mmc_card *card );

that's it. one function, one argument, returns an int. clean. iconic. 💅

---

💖 ARGUMENTS 💖

• card — the MMC card associated with the HPI transfer. yes bestie, this is the card we're interrupting. the main character of the operation, if you will. 👑

---

🔥 DESCRIPTION 🔥

so what actually happens? the function issues a High Priority Interrupt, and then it checks the card status until it's out-of prg-state. 🫶

literally that's the whole bit — issue the HPI, then keep checking the card status until the card is no longer in prg-state. the way that this is just a polite little "hey, wrap it up" loop. 😭

ngl, "out-of prg-state" is the finish line here. the checking continues until the card gets there. that's the condition, that's the goal, periodt. ⭐
