STRUCT USER_FP_STRUCT(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME

okay so bestie, welcome to the Kernel API Manual entry for struct user_fp_struct(9) — user floating point registers, main character energy only. ✨

🦋 SYNOPSIS

struct user_fp_struct {
           __u64 fr[32];
        };

🎀 Members

The member lineup is literally the struct above — __u64 fr[32]; is the whole cast in this section. 💅

💅 Description

This is the user-visible floating point register state structure. No cap: it uses the same layout and size as elf_fpregset_t — same fit, same vibe. 🫶

It can be accessed through PTRACE_GETREGSET with NT_PRFPREG, and through PTRACE_GETFPREGS. Slay. 🌸
