omap44xx_prm_ocp_barrier(9)

💅 omap44xx_prm_ocp_barrier — like, the Kernel API Manual, bestie 🎀

okay so buckle up, this is omap44xx_prm_ocp_barrier(9) from the Kernel API Manual and it's literally a one-function wonder ✨

---

🌸 NAME 🌸

omap44xx_prm_ocp_barrier — forces all those buffered MPU writes headed for the PRM to actually finish, no cap 💅

---

🦋 SYNOPSIS 🦋

void omap44xx_prm_ocp_barrier (void );

---

🍓 ARGUMENTS 🍓

• void — no arguments, bestie. nothing. zero. she takes nothing and she gives nothing back 🫶

---

💜 DESCRIPTION 💜

So the whole vibe here: this function forces any buffered writes to the PRM IP block to complete. like, flush them, make them land, periodt 🔥

And why do we care? because the PRM IRQ handler literally reads and writes directly to the IP block, and if those writes are still chilling in a buffer somewhere it's giving race-condition energy 😭 so this barrier is what keeps things from getting messy after acknowledging or clearing IRQ bits 👑

Also: no return value. she doesn't return anything. she just does the thing and dips 🙈
