💅 ath5k_hw_update_mib_counters(9) — the Kernel API Manual page, bestie edition

okay so this is a page from the Kernel API Manual and it's all about ath5k_hw_update_mib_counters, which is lowkey one of those tiny functions that keeps your wifi from being a whole mess. no cap.

✨ NAME ✨

ath5k_hw_update_mib_counters — Update MIB counters (mac layer statistics). that's it, that's the vibe: it refreshes your mac layer stats 🎀

🦋 SYNOPSIS 🦋

void ath5k_hw_update_mib_counters (struct ath5k_hw *ah );

literally just the one argument, she's not complicated 💅

🌸 ARGUMENTS 🌸

  • ah — The struct ath5k_hw. that's the hardware struct, the main character of this whole story 👑

💖 DESCRIPTION 💖

okay so what she does is: she reads MIB counters from the PCU and updates the sw statistics. the way that works is she's called after a MIB interrupt — because one of these counters might have hit its maximum and triggered that interrupt — so she gets to go in and read the counter and clear it. read + clear, both, periodt. ✨

it's giving "cleanup crew but make it glamorous" honestly 🧚

⚠️ NOTE ⚠️

Is called in interrupt context! so like… be normal about it, bestie. no sleeping, no blocking, no doing the most in there. interrupt context is not the place for a main character monologue 😭

🔥 SEE ALSO 🔥
