iwl_mvm_update_smps(9)

💅 iwl_mvm_update_smps(9) — from the Kernel API Manual, bestie

Okay so picture this: it's a void function (so it returns literally nothing, don't @ me), and it lives in the Kernel API Manual. Its whole entire job? Get a request to change the SMPS mode. That's it. That's the gig. 🎀

✨ SYNOPSIS ✨

void iwl_mvm_update_smps (struct iwl_mvm *mvm , struct ieee80211_vif
*vif , enum iwl_mvm_smps_type_request req_type , enum
ieee80211_smps_mode smps_request , unsigned int link_id );

Five arguments, zero return value, maximum main character energy. 💅

🫶 ARGUMENTS 🫶

• mvm — the driver data. like, the driver's whole personality in one pointer, iykyk.
• vif — a pointer to the ieee80211_vif structure. pointer bestie, handle with care.
• req_type — the part of the driver who's calling for a change. yes, who's calling. it's giving "which department filed this request" 🗂️
• smps_request — the actual request to change the SMPS mode. the whole point fr fr.
• link_id — for MLO it's the link_id; otherwise 0, which is the deflink. zero means default, no cap.

🌸 DESCRIPTION 🌸

So this function gets a requst — and yes, the original spelling is literally "requst", we are NOT fixing it, it's iconic — to change the SMPS mode, and then it changes the SMPS mode according to all the other requests in the driver. 👑

Lowkey the vibe check here is: it's not just obeying you, it's looking at every single request floating around the driver and making the change that respects all of them. Team player behavior. Periodt.

• iwl_mvm_send_lq_cmd(9) — the other icon in the friend group 🌈

ngl, if you're poking at SMPS modes in the iwlwifi mvm driver, these two are your ride-or-dies. 🫶
