STRUCT DPU_SSPP_SUB_BLKS(9)

💅 struct dpu_sspp_sub_blks(9) — Kernel API Manual energy ✨

okay so bestie, welcome to section 9 of the Kernel API Manual, and today's main character is struct dpu_sspp_sub_blks 🎀

---

🌸 NAME 🌸

struct dpu_sspp_sub_blks — SSPP sub-blocks common: a pointer to the common configurations that all the sub blocks share 🫶

---

✨ SYNOPSIS ✨

struct dpu_sspp_sub_blks {
    u32 max_per_pipe_bw;
    u32 qseed_ver;
    struct dpu_scaler_blk scaler_blk;
    struct dpu_pp_blk csc_blk;
    struct dpu_sspp_v13_rec_blk sspp_rec0_blk;
    struct dpu_sspp_v13_rec_blk sspp_rec1_blk;
    const u32 *format_list;
    u32 num_formats;
    const struct dpu_rotation_cfg *rotation_cfg;
 };

like, that's the whole shape of it, no cap 💀 — copy it exactly if you're typing it out, bestie, every field counts 🔥

👑 Members 👑

• max_per_pipe_bw — the maximum allowable bandwidth of this pipe, measured in kBps 📶 like that's the ceiling, she will not go past it 💅
• qseed_ver — the qseed version 🌱 literally just that, the version of qseed, iykyk
• scaler_blk — the scaler block field ✨ (the manpage doesn't spell it out further, so I'm not gonna invent lore, bestie 🙈)
• csc_blk — the csc block field 🎀 (same deal — it's listed, it's there, no extra description attached 💜)
• format_list — pointer to the list of supported formats 📋 the whole menu of what's allowed, basically
• num_formats — number of supported formats 🔢 like how many things are on that list fr fr

ok ngl the original doesn't describe sspp_rec0_blk, sspp_rec1_blk or rotation_cfg in the Members section even though they're sitting right there in the struct — so I'm not gonna make up ✨vibes✨ about them. They're in the SYNOPSIS, they're real, they just didn't get a write-up 💀
