ath5k_get_rate_pcal_data(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ath5k_get_rate_pcal_data(9) — the kernel API manual, but make it make sense 🎀

okay bestie, so this one lives in the Kernel API Manual and it's literally about squeezing the per-rate power calibration data out of your wifi hardware. no cap, it's a glow-up for your radio's target power. ✨

🦋 SYNOPSIS 🦋

void ath5k_get_rate_pcal_data (struct ath5k_hw *ah , struct
ieee80211_channel *channel , struct ath5k_rate_pcal_info *rates );

that's it. that's the whole signature. she takes three pointers and returns void — nothing comes back, she just fills in what you handed her. 💅

🌸 ARGUMENTS 🌸

  • ah — the struct ath5k_hw *ah, aka your hardware handle, your main character. 👑
  • channel — the struct ieee80211_channel, the channel we're doing all this for.
  • rates — the struct ath5k_rate_pcal_info to fill. you bring the container, she brings the data. 🫶

✨ DESCRIPTION ✨

so here's the vibe: for a given frequency, she grabs the surrounding per-rate power calibration data — the calibration points on either side of where you're at — and then interpolates between those power values. why? to set the max target power that the hw can support for each rate on this frequency. 🔥

interpolation is the moment, honestly. she's not just picking a number, she's reading between the lines (and between the frequencies) to give every rate the power ceiling it deserves. ⭐

💜 SEE ALSO 💜

okay this list is long but every single one is here, no skipping, because that's just disrespectful to the kernel. 🌈

🫶 little reminder: ath5k_get_interpolated_value(9) is right there in the list, so bestie, don't go reinventing interpolation yourself before you read that one.

and that's the whole page, babes 💖 this one's from ./drivers/net/wireless/ath/ath5k, dated October 2026 — go forth and calibrate those rates, you iconic thing. 🎀🦋💅
