_pte(9)

💖 NAME 💖

okay so _pte(9) is from the Kernel API Manual, and it's literally the useful constructor for union pte — a tiny little glow-up helper, no cap. It's giving “constructor for union pte,” periodt. 🫶

✨ SYNOPSIS ✨

union pte _pte (kvm_pfn_t pfn , bool writable , bool dirty , bool
       special );

🎀 ARGUMENTS 🎀

• pfn — the pfn this pte should point to, fr fr.
• writable — whether the pte should be writable. yes/no bool energy.
• dirty — whether the pte should be dirty. is it dirty? this bool has the answer.
• special — whether the pte should be marked as special. special little guy status: this bool.

🦋 DESCRIPTION 🦋

The pte is also marked as young and present, bestie — both of those are in the mix.

If the pte is marked as dirty, it gets marked as soft-dirty too.

If the pte is not dirty, the hardware protect bit is set (independently of the write softbit); this way proper dirty tracking can be performed. proper dirty tracking, iconic.

🌸 RETURN 🌸

It returns a union pte value. that's the whole return, periodt.
