📦 version 7.3.1, in nixpkgs unstable

💤 lbs_set_ps_mode(9) — the kernel API manual, but make it cute 💤

okay so we're in the Kernel API Manual today bestie, and the star of the show is lbs_set_ps_mode — literally the function that Sets the Power Save mode. that's it, that's the vibe. your wifi card is gonna take a lil nap and this is the girl who tucks it in 😴✨

🌸 SYNOPSIS 🌸

int lbs_set_ps_mode (struct lbs_private *priv , u16 cmd_action , bool block );

like, look at that signature. int going in, int coming out, three little args in the middle. she's serving function prototype realness 💅

🎀 ARGUMENTS 🎀

  • priv — a pointer to the struct lbs_private structure. this is the main character of the whole libertas situation, hand her over and she'll know what to do 🫶
  • cmd_action — the Power Save operation you want. it's a u16, and the two values you can pass are PS_MODE_ACTION_ENTER_PS or PS_MODE_ACTION_EXIT_PS. so basically: going to sleep, or waking up. that's the whole plot 🌙 / ☀️
  • block — a bool that decides whether to block on a response or not. true = sit there and wait for the reply like a loyal bestie, false = send it and keep it moving, no strings attached 🦋

⭐ RETURN ⭐

0 on success, error on failure. that's it. zero is the slay outcome, anything else means something went sideways — no cap 💀

eighteen whole entries, we counted, we did not skip a single one, periodt 👑

quick reminder bestie: cmd_action only takes PS_MODE_ACTION_ENTER_PS or PS_MODE_ACTION_EXIT_PS. don't freestyle it, the manpage said so and I'm just the messenger 🙈

okay that's the whole page!! this cutie came out of ./drivers/net/wireless/marvell... and she's dated October 2026, filed under lbs_set_ps_mode(9) — go take a nap, you earned it 💤🎀💖
