Hi
I tried ftrace with the linus git 2.6.29 rc-6, & rc-8, but I always seem to
get empty trace! Am I doing something wrong?
This is what I did.
linux-glcc:/data/git/linux-2.6 # cd /sys/kernel/debug/tracing/
linux-glcc:/sys/kernel/debug/tracing # cat available_tracers
function_graph function sysprof sched_switch nop
linux-glcc:/sys/kernel/debug/tracing # echo sched_switch > current_tracer
linux-glcc:/sys/kernel/debug/tracing # echo 1 > tracing_enabled
linux-glcc:/sys/kernel/debug/tracing # cat tracing_enabled
1
linux-glcc:/sys/kernel/debug/tracing # cat trace
# tracer: sched_switch
#
# TASK-PID CPU# TIMESTAMP FUNCTION
# | | | | |
linux-glcc:/sys/kernel/debug/tracing # echo "mark" > trace_marker
linux-glcc:/sys/kernel/debug/tracing # cat trace
# tracer: sched_switch
#
# TASK-PID CPU# TIMESTAMP FUNCTION
# | | | | |
linux-glcc:/sys/kernel/debug/tracing # cat tracing_on
1
linux-glcc:/sys/kernel/debug/tracing # echo "mark-two" > trace_marker
linux-glcc:/sys/kernel/debug/tracing # cat tracing_on
1
linux-glcc:/sys/kernel/debug/tracing # cat trace
# tracer: sched_switch
#
# TASK-PID CPU# TIMESTAMP FUNCTION
# | | | | |
linux-glcc:/sys/kernel/debug/tracing # echo 0 > tracing_enabled
linux-glcc:/sys/kernel/debug/tracing # cat trace
# tracer: sched_switch
#
# TASK-PID CPU# TIMESTAMP FUNCTION
# | | | | |
linux-glcc:/sys/kernel/debug/tracing #
Attached is the config used.
Thanks

Hi Nikanth,
Does latest -tip tree work for you with about the same config?

your operation seems fine and your .config seems fine too.
but my box works ftrace well on 2.6.29-rc8.
hmm...
Could you post followin operation result and dmesg?
# cat failures
# cat current_tracer
# cat trace_options
# cat buffer_size_kb
# cat dyn_ftrace_total_info
# cat trace_options
# cat set_ftrace_filter

I've tested your config on latest mainline but not problem
occured with the sched switch tracer.
Does it work with other tracers?

I tried "function" as well. None of the tracers seems to work.

I already sent it to the list. Sorry I missed your id. Here we go again.
BTW this is inside qemu-kvm, and could be a qemu issue?! Even though it could
be a qemu bug, no idea what exactly is failing, so that I could report it to
qemu developers.
Also it would be very nice if CONFIG_FTRACE_STARTUP_TEST can detect this as
well.
Thanks

In terms of tracing it should just look like some weird old CPU with
few capabilities and long delays. Nothing in ftrace depends on CPU
capabilities (that wasnt present in pentia) so this is weird.
Perhaps some timestamping problem? Virtual machines tend to have
trouble with the TSC. Or code patching problems? But that does not
explain the lack of explicit scheduler events.
Or perhaps the fact that qemu sessions tend to boot with barely any
RAM. Maybe the ringbuffer size is very low?

Nope, it is not a qemu problem, but ftrace. Most probably, it shouldn't work on
real hardware as well with my config. i.e., CONFIG_CPUMASK_OFFSTACK = y
and NR_CPUS = 4096 via CONFIG_MAXSMP.
The tracing_buffer_mask was getting freed and the bitmask was all zeros. And
for_each_tracing_cpu() never looped. Here is the patch that fixes the issue
for me. Tested only on qemu-kvm. ;)
Steve, Can you merge this.
Thanks
