setup_purgatory_ppc64(9)

🌸 setup_purgatory_ppc64 — NAME 💅

okay bestie, so this is setup_purgatory_ppc64, and it's literally from the Kernel API Manual (yes, the big one, we're fancy now 👑). What does it do? It initializes the PPC64-specific global variables of the purgatory (look at her, being all arch-specific and special ✨), and then it calls setup_purgatory() to initialize the common global variable. Two jobs, one function, main character energy fr fr.

🫶 SYNOPSIS

int setup_purgatory_ppc64 (struct kimage *image , const void *slave_code
, const void *fdt , unsigned long kernel_load_addr , unsigned long
fdt_load_addr );

🎀 ARGUMENTS ✨

• image — the kexec image. that's her.
• slave_code — the slave code for the purgatory 👀
• fdt — the Flattened device tree for the next kernel 🌳
• kernel_load_addr — the address where the kernel is loaded 📍
• fdt_load_addr — the address where the flattened device tree is loaded 📍

💖 DESCRIPTION 🌈

Returns 0 on success, and a negative errno on error. that's it, that's the vibe check 🦋

ngl bestie, this one's short but she's important. 0 = slay, negative errno = something went off, go read the errno 💀
