It includes a few cosmetic changes and now handles firmware crashes (Thanks Michal and Chun-Yeow!). The fft_eval tool has also been updated based on the new patchset, and now supports both ath9k and ath10k sample formats in the same branch, which has been merged into master [1]. Please make sure to use the latest version of both fft_eval and this patchset for testing. The count issue is still open: Even when a count is specified, the hardware seems to send endless samples. It seems to work most of the time in VHT80 mode though, but in HT20 and HT40 the count value seems to be ignored. To reproduce this, start hostapd with the desired channel width and do: echo 8 > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_count echo manual > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl echo trigger > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl cat /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan0 >> /tmp/fft.dump Repeating the last line and checking the filesize will easily show whether ath10k still sends samples or not. We would expect 8 samples in this configuration. See the patch for more information on the changes.
