__acpi_pm_prepare(9)

💖 NAME 💖

okay so bestie, welcome to __acpi_pm_prepare(9) from the Kernel API Manual 💖 This one is literally about preparing the platform to enter the target state. 🎀

🌸 SYNOPSIS 🌸

int __acpi_pm_prepare (void );

🦋 ARGUMENTS 🦋

• void — no arguments. none. zero. the void is voiding. 💀

💅 DESCRIPTION 💅

This is the prep step, bestie. If necessary, it sets the firmware waking vector and does the arch-specific nastiness to get the wakeup code to the waking vector. That's the whole vibe: firmware waking vector gets set when needed, the arch-specific messy bits get handled, and the wakeup code is pointed at the waking vector. ✨
