This -v6 revision incorporates the feedbacks of -v5 revision from Frederic Weisbecker, the most important changes include: 1. tracing: add IRQENTRY_EXIT section for MIPS Tag the mips irq entry functions with "__irq_entry". 2. "notrace" relative patches To avoid hanging on mips_timecounter_read() when using function graph tracer, we need not to trace the subroutines called by mips_timecounter_read(). for the mips specific subroutines, we use __notrac_funcgraph to tag them. For the common timecounter_read_* functions, we add a new __arch_notrace flag/macro to include/linux/ftrace.h for the arch specific requirement, and use it to tag them. and then we define the macro in arch/mips/include/asm/ftrace.h to make it take effect for MIPS. All of the latest update have been pushed into: git://dev.lemote.com/rt4ls.git linux-mips/dev/ftrace-upstream Thanks & Regards, Wu Zhangjin Wu Zhangjin (13): tracing: convert trace_clock_local() as weak function tracing: add mips_timecounter_read() for MIPS tracing: add MIPS specific trace_clock_local() tracing: add static function tracer support for MIPS tracing: enable HAVE_FUNCTION_TRACE_MCOUNT_TEST for MIPS tracing: add an endian argument to scripts/recordmcount.pl tracing: add dynamic function tracer support for MIPS tracing: add IRQENTRY_EXIT section for MIPS tracing: Add __arch_notrace for arch specific requirement tracing: not trace the timecounter_read* in kernel/time/clocksource.c tracing: not trace mips_timecounter_read() for MIPS tracing: add function graph tracer support for MIPS tracing: add dynamic function graph tracer for MIPS arch/mips/Kconfig | 5 + arch/mips/Makefile | 4 + arch/mips/include/asm/ftrace.h | 42 +++++++++- arch/mips/include/asm/irq.h | 29 +------ arch/mips/include/asm/time.h | 19 ++++ arch/mips/kernel/Makefile | 9 ++ arch/mips/kernel/csrc-r4k.c | 42 +++++++++ arch/mips/kernel/ftrace.c | 190 ++++++++++++++++++++++++++++++++++++++++ arch/mips/kernel/irq.c | 34 +++++++ arch/mips/kernel/mcount.S | 177 +++++++++++++++++++++++++++++++++++++ arch/mips/kernel/mips_ksyms.c | 5 + arch/mips/kernel/smp.c | 3 +- arch/mips/kernel/smtc.c | 21 +++-- arch/mips/kernel/time.c | 2 + arch/mips/kernel/trace_clock.c | 33 +++++++ arch/mips/kernel/vmlinux.lds.S | 1 + arch/mips/sgi-ip22/ip22-int.c | 3 +- arch/mips/sgi-ip22/ip22-time.c | 3 +- include/linux/ftrace.h | 19 ++++ kernel/time/clocksource.c | 5 +- kernel/trace/trace_clock.c | 2 +- scripts/Makefile.build | 1 + scripts/recordmcount.pl | 44 +++++++++- 23 files changed, 649 insertions(+), 44 deletions(-) create mode 100644 arch/mips/kernel/ftrace.c create mode 100644 arch/mips/kernel/mcount.S create mode 100644 arch/mips/kernel/trace_clock.c
