Rao <naveen.n.rao@linux.vnet.ibm.com> # Date: Thu Jun 27 15:29:40 2019 +0530 # # powerpc/xmon: Fix disabling tracing while in xmon # # Commit ed49f7fd6438d ("powerpc/xmon: Disable tracing when entering # xmon") added code to disable recording trace entries while in xmon. The # commit introduced a variable 'tracing_enabled' to record if tracing was # enabled on xmon entry, and used this to conditionally enable tracing # during exit from xmon. # # However, we are not checking the value of 'fromipi' variable in # xmon_core() when setting 'tracing_enabled'. Due to this, when secondary # cpus enter xmon, they will see tracing as being disabled already and # tracing won't be re-enabled on exit. Fix the same. # # Fixes: ed49f7fd6438d ("powerpc/xmon: Disable tracing when entering xmon") # Signed-off-by: Naveen N.
