STRUCT SRC_SEL(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual — this is struct src_sel(9), and it is literally the source selector 🎀.

struct src_sel — source selector. That's the whole name section, short and iconic.

🌸 SYNOPSIS 🌸

Peep the struct, no cap:

struct src_sel {
    u8 src_sel_shift;
  #define SRC_SEL_MASK    0x7;
    const struct parent_map *parent_map;
 };

and yes, SRC_SEL_MASK is 0x7 — it's right there in the struct, bestie ✨.

🎀 Members 🎀

• src_sel_shift — the lowest bit of source selection field. it's giving "where the field starts" energy 💅.
• parent_map — map from software's parent index to hardware's src_sel field. fr fr, that's the whole vibe 🦋.
