ath9k_hw_dfs_tested(9)

✨ NAME ✨

okay so this is ath9k_hw_dfs_tested(9), bestie, straight out of the Kernel API Manual — and it’s literally the function that checks if DFS has been tested with the chipset you’re using 💅✨

🌸 SYNOPSIS 🌸

bool ath9k_hw_dfs_tested (struct ath_hw *ah );

🎀 ARGUMENTS 🎀

• ah — the atheros hardware data structure, periodt 🫶

🦋 DESCRIPTION 🦋

so here’s the tea ☕: DFS support gets enabled upstream on chipsets that have passed a whole series of tests. the testing requirements are going to be documented — yes, future documentation energy, we love to see it 🙈

the desired test requirements are documented at:

https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/dfs

and once a new chipset gets properly tested, an individual commit can be used to document the testing for DFS for that chipset. iconic behavior, honestly 👑
