intel_device...runtime_init(9)

🌸 intel_device...runtime_init(9) 🌸

okay so bestie, this is the Kernel API Manual entry for intel_device...runtime_init(9) — she’s giving kernel-core main character energy, and we’re gonna get into it. 💅

---

💖 NAME 💖

intel_device_info_runtime_init — initialize runtime info

Literally the assignment: initialize runtime info. Slay.

---

✨ SYNOPSIS ✨

void intel_device_info_runtime_init (struct drm_i915_private *dev_priv
);

---

🎀 ARGUMENTS 🎀

• dev_priv — the i915 device. That’s the whole argument, bestie, no cap.

---

💅 DESCRIPTION 💅

Determine various intel_device_info fields at runtime. That’s the vibe: runtime info gets decided at runtime, periodt.

Use it when either:

• it's judged too laborious to fill n static structures with the limit when a simple if statement does the job,
• run-time checks (eg read fuse/strap registers) are needed.

This function needs to be called:

• after the MMIO has been setup as we are reading registers,
• after the PCH has been detected,
• before the first usage of the fields it can tweak.

🫶 friendly reminder: those “needs to be called” rules are not decorative. Respect the ordering, bestie.
