STRUCT DRM_PRIVACY_SCREEN_OPS(9)

✨ struct drm_privacy_screen_ops(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 today we're looking at struct drm_privacy_screen_ops — no cap, it's the whole vibe of the privacy-screen operation set. 🫶

---

🎀 NAME 🎀

struct drm_privacy_screen_ops — literally just the drm_privacy_screen operations, that's the whole thing, that's her 👑

---

🦋 SYNOPSIS 🦋

the way she's shaped, fr fr:

struct drm_privacy_screen_ops {
    int (*set_sw_state)(struct drm_privacy_screen *priv, enum
drm_privacy_screen_status sw_state);
    void (*get_hw_state)(struct drm_privacy_screen *priv);
 };

🌸 Members 🌸

bestie these are the two function pointers and they are both main characters, let's go:

• set_sw_state — called when someone wants to request a change of the privacy-screen state. and like, plot twist 🫢 the privacy-screen class code has a check in it so this does not get called when the hw_state is reporting that the state is locked. it is the driver's responsibility to update sw_state and hw_state. and heads up: this is always called with the drm_privacy_screen's lock held. always. 😌
• get_hw_state — called to request that the driver gets the current privacy-screen state from the hardware and then updates sw_state and hw_state accordingly. the core calls this right before the privacy-screen is registered in sysfs. like, right before. timing is everything ✨

---

💜 Description 💜

so what is this? it defines the operations which the privacy-screen class code may call. these functions should be implemented by the privacy-screen driver. that's it, that's the assignment, slay 💅
