STRUCT DRM_MONITOR_RANGE_INFO(9)

👑 struct drm_monitor_range_info(9) — the Kernel API Manual, bestie edition

okay so you're in the Kernel API Manual and we're talking about struct drm_monitor_range_info(9). pull up a chair, this one's actually adorable. 🎀

---

✨ NAME ✨

struct drm_monitor_range_info — literally the panel's Monitor range in EDID for &drm_display_info. that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

struct drm_monitor_range_info {
    u16 min_vfreq;
    u16 max_vfreq;
 };

two u16s. that's it. she's small but she's mighty. 🦋

---

💖 MEMBERS 💖

• min_vfreq — this is the min supported refresh rate in Hz, straight out of EDID's detailed monitor range. the floor. the lower bound. the "don't go below this" energy. 🫶
• max_vfreq — this is the max supported refresh rate in Hz, also from EDID's detailed monitor range. the ceiling. the "that's as fast as she goes" moment. 🔥

---

🌈 DESCRIPTION 🌈

so this struct is where we store a frequency range that the panel supports — and we get it by parsing EDID's detailed monitor range descriptor block. like, the monitor literally tells us its comfort zone and we just... keep it. iconic behaviour, no cap. ⭐

she's a storage struct, bestie. no functions, no side quests — just holding onto that range for &drm_display_info so the rest of the kernel can vibe check it later. 💀
