STRUCT IWL_PRPH_SCRATCH_STEP_CFG(9)

✨ NAME ✨

struct iwl_prph_scratch_step_cfg — the prph scratch step configuration 💅

okay so real talk, this is straight out of the Kernel API Manual, and it's basically the little struct that holds your step config for prph scratch. tiny struct, big main character energy 🎀

🌸 SYNOPSIS 🌸

struct iwl_prph_scratch_step_cfg {
    __le32 mbx_addr_0;
    __le32 mbx_addr_1;
};

two __le32 fields, that's the whole vibe. no cap, she's compact 🦋

💖 Members 💖

• mbx_addr_0 — bestie this one is packed, like a bitfield charcuterie board 🍓:
  • [0:7] revision
  • [8:15] cnvi_to_cnvr length
  • [16:23] cnvr_to_cnvi channel length
  • [24:31] radio1 reserved
• mbx_addr_1 — and this one's the chill one:
  • [0:7] radio2 reserved

lowkey fascinated by how much lore fits in 32 bits ngl 😭
