vdpa_get_config(9)

📦 version 7.3.1, in nixpkgs unstable

💅 vdpa_get_config — the Kernel API Manual, but make it cute ✨

Okay so bestie, listen up, because vdpa_get_config is literally the one that pulls device configuration fields out of a vDPA device, and she ate. This page lives in the Kernel API Manual, and we're about to get into it. 🎀

🌸 SYNOPSIS 🌸

void vdpa_get_config (struct vdpa_device *vdev , unsigned int offset ,
void *buf , unsigned int len );

No cap, that's the whole signature. Void return, four arguments, iconic. 💖

✨ ARGUMENTS ✨

  • vdev — the vDPA device you're operating on. Like, this is your main character right here, the device everything's happening to. 🫶
  • offset — the starting byte offset of the field you want. Basically where in the config you're pointing at. 📍
  • buf — buffer pointer to read to. This is where the data lands, so make sure it's ready to receive, bestie. 🧺
  • len — length of the configuration fields in bytes. Tell her how much you want and she'll deliver exactly that. 📏

🌈 SEE ALSO 🌈

The kernel file ./drivers/vdpa/vdpa.c is the mothership, and she's got friends — so many friends. Go say hi to all of these:

Like, that is a whole squad right there. vdpa_set_config(9) is her partner in crime, iykyk. 👑

And that's the whole page, periodt. This cutie dropped as part of the ./drivers/vdpa source situation, dated October 2026, and honestly? She's serving kernel API excellence. Slay. 💀✨🦋
