✨ DESCRIPTION ✨

so here's the tea 🍵 — this one does any reconfiguration work needed by a resume from RAM. like, your machine went to sleep, RAM kept vibing, and now everything has to wake up and look cute again 💅

and specifically? we need to restore DMA mode support on BIOSen which disabled it. yes, those BIOSen. the ones that turned DMA off while you weren't looking 🙈 so this function's whole job is handing DMA mode its crown back 👑

periodt. that's the whole description. it's giving short-and-iconic 🎀
