STRUCT DPU_CAPS(9)

💖 struct dpu_caps(9) — Kernel API Manual 💖

Ok bestie, welcome to the glow-up zone ✨ This page is all about struct dpu_caps — literally the define DPU capabilities blueprint. Think of it as the group-chat bio for the DPU: it tells you what’s supported and what the caps are, no cap 💅

---

🌸 NAME 🌸

struct dpu_caps — define DPU capabilities. Here’s the field-by-field tea, with every cap keeping its exact meaning:

• @max_mixer_width — max layer mixer line width support.
• @max_mixer_blendstages — max layer mixer blend stages or supported z order.
• @has_src_split — source split feature status.
• @has_dim_layer — dim layer feature status.
• @has_idle_pc — indicate if idle power collapse feature is supported.
• @has_3d_merge — indicate if 3D merge is supported.
• @max_linewidth — max linewidth for sspp.
• @pixel_ram_size — size of latency hiding and de-tiling buffer in bytes.
• @max_hdeci_exp — max horizontal decimation supported (max is 2^value).
• @max_vdeci_exp — max vertical decimation supported (max is 2^value).

🦋 SYNOPSIS 🦋

Serving the struct exactly as it is, bestie — no remix, no edits:

       struct dpu_caps {
           u32 max_mixer_width;
           u32 max_mixer_blendstages;
           bool has_src_split;
           bool has_dim_layer;
           bool has_idle_pc;
           bool has_3d_merge;
           u32 max_linewidth;
           u32 pixel_ram_size;
           u32 max_hdeci_exp;
           u32 max_vdeci_exp;
        };
