💖 NAME 💖

pwrdm_read_mem_retst(9) from the Kernel API Manual — get next memory bank power state. okay so this is the tiny little lookup bestie for a powerdomain's next memory bank power state. no cap. 💅

✨ SYNOPSIS ✨

int pwrdm_read_mem_retst (struct powerdomain *pwrdm , u8 bank );

🎀 ARGUMENTS 🎀

• pwrdm — a struct powerdomain *; the powerdomain you're asking about, so it can hand over the next memory bank power state.
• bank — memory bank number (0-3).

🦋 DESCRIPTION 🦋

Return the powerdomain pwrdm's next memory power state for bank x. it's giving “please tell me what this memory bank is about to do next” energy. 🫶

The return vibe check: -EINVAL if the powerdomain pointer is null, -EEXIST if the target memory bank does not exist or is not controllable, or returns the next memory power state upon success. 💖
