ath5k_get_c...unding_piers(9)

✨ NAME ✨

ath5k_get_chan_pcal_surrounding_piers — get surrounding calibration piers for a given channel. 💅

okay bestie, this is the Kernel API Manual page for ath5k_get_chan_pcal_surrounding_piers — the tiny header version gets chopped into ath5k_get_c...unding_piers(9), which is giving “my name got ate by the terminal” energy, but the full function name is right there and we’re obsessed. ✨

🌸 SYNOPSIS 🌸

void ath5k_get_chan_pcal_surrounding_piers (struct ath5k_hw *ah , struct ieee80211_channel *channel , struct ath5k_chan_pcal_info **pcinfo_l , struct ath5k_chan_pcal_info **pcinfo_r );

🎀 ARGUMENTS 🎀

• ah — the struct ath5k_hw. that’s the hardware bestie in question 🫶
• channel — the struct ieee80211_channel. the channel we’re doing all this for 💖
• pcinfo_l — the struct ath5k_chan_pcal_info to put the left cal. pier. left pier goes here, no cap 🌸
• pcinfo_r — the struct ath5k_chan_pcal_info to put the right cal. pier. right pier goes here, periodt 🎀

🦋 DESCRIPTION 🦋

okay so the whole slay here is: get the surrounding per-channel power calibration piers for a given frequency so that we can interpolate between them and come up with an appropriate dataset for our current channel. literally that’s the vibe check. 💫

we grab the calibration piers on either side, interpolate between them, and end up with the right dataset for the channel we actually care about. iconic behavior honestly. 👑
