💅 sdma_v4_4_2_vm_set_pte_pde(9)

okay so bestie, this is a page from the Kernel API Manual and it's about one very specific little function called sdma_v4_4_2_vm_set_pte_pde — say that five times fast, I dare you 😭 — and it does exactly one job: it updates the page tables using sDMA. That's the whole vibe. Let's get into it. 🦋
