Subject: [PATCH 0/3] ARM: perf: allow tracing with kernel tracepoints events
Date: Fri, 27 Jun 2014 16:57:44 +0200 [thread overview]
Message-ID: <1403881067-22690-1-git-send-email-jean.pihet@linaro.org> (raw)
- Robustify the user backtrace code, as done on other architectures.
- Provide the symbols resolution when triggering from tracepoints.
Tested with perf record and tracepoints triggering (-e <tracepoint>), with
unwinding using fp (--call-graph fp) and dwarf info (--call-graph dwarf).
Jean Pihet (3):
ARM: perf: Check that current->mm is alive before getting user
callchain
ARM: perf: disable the pagefault handler when reading from user space
ARM: perf: allow tracing with kernel tracepoints events
