pvr_mmu_flush_request_all(9)

pvr_mmu_flush_request_all(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one is short, iconic, and lowkey all about asking for a flush of all MMU caches so pvr_mmu_flush_exec() can do its thing later. no cap, let's get into it 🫶

🌸 NAME 🌸

pvr_mmu_flush_request_all — request a flush of all MMU caches when you subsequently call pvr_mmu_flush_exec(). that's the whole name, and it ate 💖

✨ SYNOPSIS ✨

void pvr_mmu_flush_request_all (struct pvr_device *pvr_dev );

🎀 ARGUMENTS 🎀

• pvr_dev — the target PowerVR device, bestie. that's the one you're pointing at 💫

🦋 DESCRIPTION 🦋

okay so the actual rule: this function must be called following any possible change to the MMU page tables. like, mandatory mandatory. not "whenever you feel like it" energy — after any possible change, periodt 💅
