STRUCT ISST_IF_MSR_CMD(9)

💅 struct isst_if_msr_cmd(9) 💅

okay so bestie, welcome to the Kernel API Manual page for struct isst_if_msr_cmd(9) — the struct that defines an msr command. it's giving tiny but iconic, and we are gonna go through every single field, no cap. 🫶✨

🎀 NAME 🎀

struct isst_if_msr_cmd — structure to define msr command. that's the name, that's the vibe. 💖

🌸 SYNOPSIS 🌸

       struct isst_if_msr_cmd {
           __u32 read_write;
           __u32 logical_cpu;
           __u64 msr;
           __u64 data;
        };

💖 Members 💖

• read_write — value 0: Read, 1: Write. literally the read/write switch, bestie. 💅
• logical_cpu — logical CPU number.
• msr — MSR number.
• data — for write operation, data to write, for read place holder.

🦋 Description 🦋

this struct is here to specify an MSR command related to PUNIT. that's the job, that's the whole point. ✨
