xe_pt_populate_empty(9)

💅 NAME

xe_pt_populate_empty — fills a page-table bo with scratch entries or zero entries, whichever one applies 🫶

✨ SYNOPSIS

void xe_pt_populate_empty (struct xe_tile *tile , struct xe_vm *vm ,
struct xe_pt *pt );

🎀 ARGUMENTS

• tile — the tile whose scratch pagetable we're pulling from, bestie. That's the one we use. 💫
• vm — the vm we're populating for, like who is this even for, it's for this vm.
• pt — the pagetable whose bo we're initializing. yeah. that bo. 🔥

🦋 DESCRIPTION

okay so here's the whole vibe: xe_pt_populate_empty populates the page-table bo of pt with entries that point into the tile's scratch page-table tree — if there is one. 🌸

otherwise? it populates with zeros. that's it. that's the whole function. no cap. ✨
