omap3xxx_prm_ocp_barrier(9)

Hiii bestie 💖 welcome to the Kernel API Manual page for omap3xxx_prm_ocp_barrier(9) — yes, she’s iconic, yes, she’s niche, and yes, we’re getting into it.

🌸 NAME 🌸

omap3xxx_prm_ocp_barrier — force buffered MPU writes to the PRM to complete

✨ SYNOPSIS ✨

void omap3xxx_prm_ocp_barrier (void );

🎀 ARGUMENTS 🎀

• void — no arguments, periodt. Literally none, bestie 🫶

💅 DESCRIPTION 💅

Okay so this one forces any buffered writes to the PRM IP block to complete. Like, actually complete. No lingering in the buffer, no “I’ll get to it later” energy 💀

It’s needed by the PRM IRQ handler, which reads and writes directly to the IP block, to avoid race conditions after acknowledging or clearing IRQ bits. So yeah, she’s doing important main-character work 🔥

No return value. It’s giving void, and it’s giving exactly that 😌
