STRUCT CPPI5_TR_TYPE1_T(9)

🌸 NAME 🌸

okay bestie, welcome to the struct cppi5_tr_type1_t(9) page from the Kernel API Manual ✨ — and this one is literally the Type 1 (Two dimensional data move) TR (32 byte) struct. That’s the whole name, no cap: Type 1 (Two dimensional data move) TR (32 byte) 💅

✨ SYNOPSIS ✨

here’s the shape of it, bestie — keep it exact, because struct definitions are not a vibe to improvise 🫶:

       struct cppi5_tr_type1_t {
           cppi5_tr_flags_t flags;
           u16 icnt0;
           u16 icnt1;
           u64 addr;
           s32 dim1;
        };

🎀 Members 🎀

these are the members, and every single one is doing main character work 💖:

• flags — TR flags (type, triggers, event, configuration). it’s giving settings-page energy 💅
• icnt0 — Total loop iteration count for level 0 (innermost). the innermost loop’s total, periodt 🌀
• icnt1 — Total loop iteration count for level 1. the next loop’s total, no cap ✨
• addr — Starting address for the source data or destination data. literally where the data starts, bestie 📍
• dim1 — Signed dimension for loop level 1. signed, so keep that in mind 🫡
