mshv_region_range_fault(9)

🌸 NAME 🌸

Okay bestie, welcome to the mshv_region_range_fault(9) page from the Kernel API Manual 💖. mshv_region_range_fault is literally the function that handles memory range faults for a given region. Periodt.

✨ SYNOPSIS ✨

Like, here's the signature, no cap:

       int mshv_region_range_fault (struct mshv_mem_region *region , u64
       page_offset , u64 page_count );

🎀 ARGUMENTS 🎀

• region — pointer to the memory region structure. Iconic.
• page_offset — offset of the page within the region.
• page_count — number of pages to handle.

🦋 DESCRIPTION 🦋

Okay so here's the tea: this function resolves memory faults for a specified range of pages within a memory region. It uses HMM (Heterogeneous Memory Management) to fault in the required pages, and it updates the region's page array. Literally the main character energy of fault handling 💅.

🌈 RETURN 🌈

0 on success, negative error code on failure. Slay on success, sad vibes on failure 😭.
