From 18353749170033405790ed62a3ae2aa2d3d8a82a Mon Sep 17 00:00:00 2001 From: Ashok Raj Nagarajan Date: Fri, 5 Feb 2016 21:12:49 +0530 Subject: [PATCH] ath10k: add hw_rev to trace events to support pktlog pktlog data is different between firmware variants (eg. 10.2 vs 10.4). To have a unified user space script to decode pktlog trace events generated, it is desirable to know which firmware variant has provided the events and thereby decode the pktlogs appropriately. Hardware revision (hw_rev) helps to determine the firmware variant sending these trace events. So add hw_rev to trace events.
