STRUCT I915_HDCP_ARBITER(9)

💅 struct i915_hdcp_arbiter — ok bestie, listen

So this is struct i915_hdcp_arbiter from the kernel API manual — it's the little matchmaker struct that lets the i915 driver and the hdcp drivers talk to each other so the HDCP2.2 services can actually happen. It's giving "group chat admin" energy, fr fr 🔥

✨ SYNOPSIS ✨

struct i915_hdcp_arbiter {
    struct device *hdcp_dev;
    const struct i915_hdcp_ops *ops;
    struct mutex mutex;
 };

Three members. That's it. Iconic, minimal, no notes 🎀

👑 Members 👑

• hdcp_dev — the device that provides the HDCP2.2 service, coming at you straight from the MEI Bus. She's the one actually doing the HDCP2.2 work 💖
• ops — the ops implemented by the hdcp driver or intel_hdcp_gsc, and these are the ones the i915 driver uses. Like, i915 doesn't do it herself, she calls up her bestie's function pointers, iykyk 🌸
• mutex — a struct mutex whose whole entire job is to protect the two members above. Do not touch them without her, periodt 🔒✨

All the lore is right there 🦋

lowkey a whole struct about cooperation and mutual protection... the way that's literally friendship 💜

And that's the page bestie! It lives at ./include/drm/intel in the Kernel API Manual, dated October 2026, all under the name struct i915_hdcp_arbiter(9) — slay, go read the source, ily, bye 🫶🌸
