💅 pvr_page_table_l0_remove — Kernel API Manual 🎀

okay bestie, so this is a page from the Kernel API Manual and honestly it's lowkey iconic: we're removing a physical page from a level 0 page table. sounds scary, it's actually just page-table housekeeping. let's go ✨

🌸 NAME 🌸

pvr_page_table_l0_remove — remove a physical page from a level 0 page table. periodt. 💅

🦋 SYNOPSIS 🦋

void pvr_page_table_l0_remove (struct pvr_mmu_op_context *op_ctx );

🎀 ARGUMENTS 🎀

  • op_ctx — the target MMU op context, and it's the one pointing at the L0 entry you're about to remove. it's giving "main character pointer energy" ✨

💖 DESCRIPTION 💖

so here's the tea 🍓: if this function ends up making the L0 table empty, then that table gets removed from its parent L1 page table and gets destroyed. gone. bye. no cap. 💀

and now the part you cannot skip, bestie:

It is the caller's responsibility to make sure op_ctx.curr_page points to a valid L0 entry. like, that's on you, not on the function. please do your vibe check first 🙈
