STRUCT IOSM_RPSI_CMD(9)

💅 NAME

okay so bestie, welcome to struct iosm_rpsi_cmd — literally the Structure for RPSI Command ✨ and yes we're gonna get into it. this is from the Kernel API Manual section 9, so buckle up 🎀

---

✨ SYNOPSIS

here's the whole entire glow-up, verbatim, no cap:

struct iosm_rpsi_cmd {
    union iosm_rpsi_param_u param;
    __le16 cmd;
    __le16 crc;
 };

that's it. that's the struct. three members. lowkey iconic for how much it's carrying 🫶

---

🌸 MEMBERS

okay so let's meet the cast, they each have exactly one job and they're doing it:

• param — a union iosm_rpsi_param_u, and its whole main character moment is that it's used to calculate CRC 🧮✨
• cmd — a __le16 that stores the RPSI command 💖 this is the actual vibe of what we're asking for
• crc — a __le16 that stores the CRC value 🔥 the little checksum bestie that keeps everyone honest

ngl, the param member is literally there so the CRC can be computed — that's the entire lore, don't overthink it 💅
