ath5k_hw_rf_...inf_readback(9)

💖 NAME 💖

okay bestie, welcome to the ath5k_hw_rf_...inf_readback(9) page from the Kernel API Manual — we're doing this 💅

ath5k_hw_rf_check_gainf_readback — Validate Gain_F feedback from detector ✨

---

✨ SYNOPSIS ✨

bool ath5k_hw_rf_check_gainf_readback (struct ath5k_hw *ah );

---

🎀 ARGUMENTS 🎀

• ah — the struct ath5k_hw, aka the main character of this function 🫶

---

🦋 DESCRIPTION 🦋

so basically, this function checks if the current gain_F measurement is in the range of our power detector windows 👀 if we get a measurement outside range, we know it's not accurate — because detectors literally can't measure anything outside their detection window — so we must ignore it, no cap 😭

Returns true if readback was O.K. or false on failure 💖

mwah 💋 this cutie came from ./drivers/net/wireless/ath/ath5k and is dated October 2026 — and yeah, it's still the ath5k_hw_rf_...inf_readback(9) page from the Kernel API Manual. bye bestie, go read some PHY code 🫶💖
