pwrdm_save_context(9)

💾 pwrdm_save_context(9) 💾

okay bestie, welcome to the Kernel API Manual 💖 you pulled up pwrdm_save_context(9), and we're gonna get you comfy with it. This is the little helper whose whole personality is: save powerdomain registers. Let's go ✨

🌸 NAME 🌸

pwrdm_save_context — save powerdomain registers

🦋 SYNOPSIS 🦋

int pwrdm_save_context (struct powerdomain *pwrdm , void *unused );

🎀 ARGUMENTS 🎀

• pwrdm — so the original manpage literally gives this one -- undescribed --, bestie 😭. In the synopsis it's struct powerdomain *pwrdm. That's the whole description we've got, no cap.
• unused — same situation: the manpage says -- undescribed -- for this too 🙈. In the synopsis it's void *unused.

💅 DESCRIPTION 💅

okay so here's the plot: register state is going to be lost due to a suspend or hibernate event 😭 that's the crisis. pwrdm_save_context is the main character that saves the powerdomain registers 💾✨. That's the assignment. It's giving "back it up before the nap" energy, and honestly? Iconic.

highkey important: the original says the register state is going to be lost due to a suspend or hibernate event, and the function saves the powerdomain registers. That's the whole deal 💖.
