STRUCT ISST_TPMI_INSTANCE_COUNT(9)

💖 struct isst_tpmi_instance_count(9) 💖

okay so bestie, this is the Kernel API Manual page for struct isst_tpmi_instance_count(9) — and yes, it is literally about getting the number of TPMI instances per socket. iconic. ✨

🌸 NAME 🌸

struct isst_tpmi_instance_count — Get number of TPMI instances per socket. That's the assignment, and it ate. 💅

🎀 SYNOPSIS 🎀

struct isst_tpmi_instance_count {
    __u8 socket_id;
    __u8 count;
    __u16 valid_mask;
 };

🌈 Members 🌈

• socket_id — Socket/package id. iykyk, it's the socket/package identifier. 🫶
• count — Number of instances. Literally the count, no cap. 🔥
• valid_mask — Mask of instances as there can be holes. yes, holes are real, so this mask is doing the work. 🕳️✨

🦋 Description 🦋

This is the structure used to get TPMI instances information using IOCTL ISST_IF_COUNT_TPMI_INSTANCES. That's the whole vibe — it's the struct for that IOCTL info, periodt. 💖
