for_each_ph...usable_range(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so bestie, meet for_each_physmem_usable_range(9) — the early online memory range iterator straight from the Kernel API Manual. yes, the page header shortens her to for_each_ph...usable_range(9), but the full name is the main character here. 💅

🌸 SYNOPSIS 🌸

for_each_physmem_usable_range (i , p_start , p_end );

🎀 ARGUMENTS 🎀

  • i — an integer used as loop variable. literally the loop girlie. 🔁
  • p_start — ptr to unsigned long for start address of the range.
  • p_end — ptr to unsigned long for end address of the range.

🦋 DESCRIPTION 🦋

She walks over detected online memory ranges below usable limit. that's the whole vibe — range by range, staying under the usable limit. ✨
