This patchset add spectral scan capability on HT40 channels for ath9k. In particular: *[PATCH 1/2]: add nf parameter to ath9k_hw_getchan_noise() to compute noise floor for ext chains *[PATCH 2/2]: parse FFT samples on HT40 channels Changes to the previous patchset: * add channel_type field in fft_sample_ht20_40 structure to indicate HT40 type (NL80211_CHAN_HT40MINUS or NL80211_CHAN_HT40PLUS) * fix some checkpatch errors Spectral scan has been tested using Simon Wunderlich's userspace program (https://github.com/simonwunderlich/FFT_eval) on HT20 channels and using a Qt-Qwt program (https://github.com/LorenzoBianconi/ath_spectral) on HT40 channels Regards, Lorenzo Lorenzo Bianconi (2): ath9k: add noise floor parameter to ath9k_hw_getchan_noise ath9k: add HT40 spectral scan capability drivers/net/wireless/ath/ath9k/ath9k.h | 29 +++++++ drivers/net/wireless/ath/ath9k/calib.c | 10 +-- drivers/net/wireless/ath/ath9k/calib.h | 3 +- drivers/net/wireless/ath/ath9k/hw.c | 2 +- drivers/net/wireless/ath/ath9k/link.c | 3 +- drivers/net/wireless/ath/ath9k/recv.c | 146 ++++++++++++++++++++++++--------- 6 files changed, 147 insertions(+), 46 deletions(-) -- 1.8.1.2 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
