ath5k_hw_write_ofdm_timings(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ath5k_hw_write_ofdm_timings(9) — like, the Kernel API Manual bestie 🎀

okay so real talk, this is a section 9 kernel API page for ath5k_hw_write_ofdm_timings, and it's lowkey niche but highkey iconic if you're deep in the ath5k wifi trenches. let's get into it ✨

🌸 NAME 🌸

ath5k_hw_write_ofdm_timings — sets the OFDM timings on the AR5212. that's it, that's the whole vibe 💅

🦋 SYNOPSIS 🦋

int ath5k_hw_write_ofdm_timings (struct ath5k_hw *ah , struct
       ieee80211_channel *channel );

like, one function, two args, returns an int. she's simple, she's focused, she knows what she wants 🫶

💖 ARGUMENTS 💖

  • ah — the struct ath5k_hw. yes bestie, THE hardware struct. the main character of this whole operation 👑
  • channel — the channel that's currently set upon reset. so like, whichever channel got locked in when the reset happened. that one 🎯

⭐ DESCRIPTION ⭐

okay so picture this: you're on reset, you're on an AR5212, and somebody has to write the delta slope coefficient — which, as the page says, is "used on pilot tracking ?" — for OFDM operation. yes the question mark is literally in the original, they were as unsure as we are, no cap 😭💀. anyway, that's what this function does.

and just so you know her place in the world: she's a helper for ath5k_hw_phy_init. support role but like, essential support. the way that every phy init needs her 🧚✨

here's the cute part: delta slope is floating point, and hardware doesn't really do "floating point" in a chill way, so we split it up — exponent on one side, mantissa on the other — and hand those values over to the hw. slay, precision, periodt 💅

and for more infos, the page thinks this patent is related, and quotes it verbatim:

buckle up bestie, this list is long — she has a whole extended friend group and we are naming every single one of them, in order, no skips 🙈

ngl that's a lot of cross-references, but she's thorough and we respect it 💜

🎀 sign-off 🎀

this cutie lives in ./drivers/net/wireless/ath/ath5k, dated October 2026, and yeah — that's the whole page, bestie. go write some delta slope coefficients, mwah 💋🌈⭐
