vmw_bo_dirty_scan_pagetable(9)

🌸 NAME 🌸

vmw_bo_dirty_scan_pagetable — Perform a pagetable scan for dirty bits ✨

okay bestie, this is the Kernel API Manual entry for vmw_bo_dirty_scan_pagetable(9). She does a pagetable scan for dirty bits, and she is lowkey iconic for it. 💅

✨ SYNOPSIS ✨

void vmw_bo_dirty_scan_pagetable (struct vmw_bo *vbo );

🎀 ARGUMENTS 🎀

• vbo — the buffer object to scan 🫶

💖 DESCRIPTION 💖

okay so what does she actually do? She scans the pagetable for dirty bits. Then she clears those bits and modifies the dirty structure with the results. The way that works is very much “scan, clear, update the dirty structure” energy. 😭

Heads up, bestie: this function may change the dirty-tracking method. That is literally what the page says, so don’t act surprised. 💀

🌈 SEE ALSO 🌈
