From cf3af74824b1bf2bd60eb6a0dd82b27f9e9236ac Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Sat, 27 Aug 2011 16:17:47 +0530 Subject: [PATCH] ath9k: Add debugfs support for mac/baseband samples This patch keep track of number of samples that includes DMA debugs registers, PCU observe, CR, channel noise, cycle conters, noisefloor history buffer and last N number of tx and rx descriptor status. These samples are grouped in table manner which dumping in debgufs. Debugfs file location: /ieee80211/phy#/ath9k/samples Signed-off-by: Rajkumar Manoharan Signed-off-by: John W.
