[RFC 2/2] ath10k: add spectral scan feature
Simon Wunderlich
sw at simonwunderlich.de
Tue Jul 15 09:32:46 PDT 2014
From: Sven Eckelmann <sven at narfation.org>
Adds the spectral scan feature for ath10k. The spectral scan is triggered by
configuring a mode through a debugfs control file. Samples can be gathered via
another relay debugfs file.
Essentially, to try it out:
ip link dev wlan0 set up
echo background > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
iw dev wlan0 scan
echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl
cat /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan0 > samples
This feature is still experimental.
