pm_pr_dbg(9)

💖 NAME 💖

okay so this is pm_pr_dbg(9) from the Kernel API Manual, and it's literally the little helper for printing pm sleep debug messages 💅✨

🎀 SYNOPSIS 🎀

pm_pr_dbg (fmt , ... );

🌸 ARGUMENTS 🌸

• fmt — the page just says -- undescribed --, so bestie, that's the entire lore 🙈
• ... — variable arguments, aka the extra stuff that gets passed through ✨

🦋 DESCRIPTION 🦋

Here's the tea, no cap 🍵:

• If pm_debug_messages_on is enabled and the system is entering/leaving suspend, print message. Slay.
• If pm_debug_messages_on is disabled and CONFIG_DYNAMIC_DEBUG is enabled, print message only from instances explicitly enabled on dynamic debug's control. Very controlled, very demure 💅
• If pm_debug_messages_on is disabled and CONFIG_DYNAMIC_DEBUG is disabled, don't print message. Periodt. 💀
