_hv_pcifront_read_config(9)

🎀 _hv_pcifront_read_config(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for _hv_pcifront_read_config — it is literally the internal PCI config read. That's the whole assignment: internal, PCI config, read. No extra lore, no cap. 💅

🌸 NAME 🌸

_hv_pcifront_read_config — Internal PCI config read. That's it, that's the function's main character energy. ✨

✨ SYNOPSIS ✨

void _hv_pcifront_read_config (struct hv_pci_dev *hpdev , int where ,
       int size , u32 *val );

🫶 ARGUMENTS 🫶

• hpdev — The PCI driver's representation of the device. Like, this is the driver's whole little model of the device, iconic.
• where — Offset within config space. It's the "where are we looking" coordinate, bestie.
• size — Size of the transfer. The amount of data on the move, periodt.
• val — Pointer to the buffer receiving the data. It's the receiving vessel for the data; the buffer catches the whole vibe.
