load_crashd...gments_ppc64(9)

🌸 NAME 🌸

okay bestie, this is load_crashdump_segments_ppc64 — she's from the Kernel API Manual and her whole job is literally initializing the additional segments you need to load the kdump kernel. no cap, that's the vibe. 💅

---

✨ SYNOPSIS ✨

int load_crashdump_segments_ppc64 (struct kimage *image , struct
       kexec_buf *kbuf );

---

🎀 ARGUMENTS 🎀

• image — the Kexec image. that's it, that's the whole description, she's a main character with a one-line bio 🫶
• kbuf — the buffer contents and the memory parameters. both. at once. multi-talented icon. ✨

---

🦋 DESCRIPTION 🦋

okay so the whole plot twist is: this function returns 0 on success, and a negative errno on error. that's the entire story. dramatic? no. useful? absolutely, because you always need to know if it ate. 😭

💜 SEE ALSO 💜

lowkey the real lore is in the kernel file ./arch/powerpc/kexec/file_load_64.c — go read her, she's iconic. 👑

ok so quick recap bestie: she lives in ./arch/powerpc/kexec, she's dated October 2026, and her page is literally named load_crashd...gments_ppc64(9) (abbreviated like a text message, iconic behavior). go forth and load those segments, slay, periodt. 💖🌈⭐
