STRUCT DRM_DSC_RC_RANGE_PARAMETERS(9)

💜 struct drm_dsc_rc_range_parameters - DSC Rate Control range parameters

okay bestie, this is the struct drm_dsc_rc_range_parameters page from the Kernel API Manual, and honestly? it's a short one but it's lowkey doing important work. let's get into it ✨

---

🌸 NAME 🌸

struct drm_dsc_rc_range_parameters — DSC Rate Control range parameters

like, the literal name of the thing. that's it. she said what she said 💅

---

🎀 SYNOPSIS 🎀

struct drm_dsc_rc_range_parameters {
    u8 range_min_qp;
    u8 range_max_qp;
    u8 range_bpg_offset;
 };

three u8 fields, no more, no less. tiny struct, main character energy, fr fr 🫶

---

🦋 Members 🦋

• range_min_qp — the Min Quantization Parameters allowed for this range. the floor. the "you cannot go lower than this" of it all 🚫
• range_max_qp — the Max Quantization Parameters allowed for this range. the ceiling. the "okay that's enough" 😭
• range_bpg_offset — the Bits/group offset to apply to target for this group. ngl the name is doing a lot of abbreviation work here but that's exactly what it says 🔥

---

✨ Description ✨

so basically this struct defines the different rate control parameters that the DSC engine uses to compress the frame. that's the whole vibe. it's giving "small but essential" 💖

no cap, every field matters, and the DSC engine is out here using all of them to do its compression thing.
