drm_module_p...r_if_modeset(9)

💅 drm_module_pci_driver_if_modeset(9)

okay so bestie, welcome to the Kernel API Manual ✨ this one is section 9, and the function/thing we're talking about is literally named drm_module_pci_driver_if_modeset (the header up top shortens it to drm_module_p...r_if_modeset(9) because apparently even the manpage got tired halfway through typing it 😭). Let's get into it 🫶

---

🌸 NAME 🌸

drm_module_pci_driver_if_modeset — Register a DRM driver for PCI-based devices ✨

---

🎀 SYNOPSIS 🎀

drm_module_pci_driver_if_modeset (__pci_drv , __modeset );

---

🦋 ARGUMENTS 🦋

• __pci_drv — the PCI driver structure, the main character of this whole situation 👑
• __modeset — an additional parameter that disables the driver, iykyk 🙈

---

💖 DESCRIPTION 💖

🚨 bestie listen — this macro is deprecated and it's only hanging around for existing drivers. It's giving legacy energy fr fr. For new drivers, use drm_module_pci_driver instead, periodt. 💅

So what does it actually do? It registers a DRM driver for devices on the PCI bus ✨

The helper macro behaves like drm_module_pci_driver with an additional driver-specific flag. And the flag's whole vibe check goes like this:

• If __modeset is 0, the driver has been disabled 💀
• If __modeset is -1, the driver state depends on the global DRM state 🌈
• For all other values, the PCI driver has been enabled 🔥

And the default should be -1 — that's the one to go with unless you've got a reason, ngl 🫶

that's the whole page, no cap 🧚💜 it lives under ./include/drm and the manpage date is October 2026, filed under the name drm_module_p...r_if_modeset(9) — go forth and register your PCI drivers responsibly, bestie 🎀🌟🍓
