STRUCT DPU_SSPP_V13_REC_BLK(9)

✨ NAME ✨

struct dpu_sspp_v13_rec_blk — the SSPP REC sub-blk info, bestie 💅

okay so this little struct is literally the glow-up of REC sub-block details, and yes, this is the 9 section of the Kernel API Manual, we're doing kernel docs today 🎀

🌸 SYNOPSIS 🌸

like, here's the whole vibe, character for character, no cap:

struct dpu_sspp_v13_rec_blk {
    char name[DPU_HW_BLK_NAME_LEN];
    u32 base;
    u32 len;
 };

🦋 Members 🦋

the three fields, and honestly? each one ate 👑

• name — a string name, and it's purely for debug purposes, so it's giving "label your stuff so future-you isn't confused" 🏷️
• base — the offset of this sub-block relative to the block offset, so think of it as the address where this little sub-block starts living 📍
• len — the register block length of this sub-block, i.e. how much register real estate it's occupying 📏

not me being obsessed with a three-field struct 😭 it's simple, it's clean, it's iconic.
