for_each_physmem_range(9)

🌸 NAME 🌸

okay bestie, meet for_each_physmem_range(9) — she's serving Kernel API Manual energy, and her whole thing is: iterate through physmem areas not included in type. no cap, that's the job 💅

✨ SYNOPSIS ✨

for_each_physmem_range (i , type , p_start , p_end );

That's the exact spell, spaces and all — do not "clean it up," bestie, she's built like that 🫶

🎀 ARGUMENTS 🎀

• i — a u64 used as the loop variable. She's literally the counter, main character energy ✨
• type — a ptr to memblock_type which excludes from the iteration; can be NULL. So if there's no type to exclude, NULL is valid and she's chill with it 💅
• p_start — a ptr to phys_addr_t for the start address of the range; can be NULL. Start-address storage? optional, iconic, no notes 🌸
• p_end — a ptr to phys_addr_t for the end address of the range; can be NULL. End-address storage? also optional, also slay 🎀
