From 7fa8886907c670d1ec328c4ca9a41db510cf5118 Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Mon, 17 Dec 2018 11:53:42 +0800 Subject: [PATCH] DM: sos_bootargs: Add panic_print parameter to help debugging Adding this parameter so that it could provide more info when kernel panic happens. And this has almost no overhead as it only uses several existing kernel APIs. The 0x1f is a bitmask for type of info to be dumped, and it means it will print task/memory/timer/lock/ftrace info when panic happens.
