This has has the benefit of not setting trace_cmdline_save before all the information for a task is saved. * Add a new API tracing_record_taskinfo_sched_switch to record task information for 2 tasks at a time (previous and next) and use it from sched_switch probe. * Preserve the old API (tracing_record_cmdline) and create it as a wrapper around the new one so that existing callers aren't affected. * Reuse the existing sched_switch and sched_wakeup probes to record tgid information and add a new option 'record-tgid' to enable recording of tgid When record-tgid option isn't enabled to being with, we take care to make sure that there's isn't memory or runtime overhead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dyn_ftrace_total_info file is used to show how many functions have been converted into nops and can be used by ftrace. The problem is that it does not get decremented when functions are removed (init boot code being freed, and modules being freed). That means the number is very inaccurate everytime functions are removed from the ftrace tables. Decrement it when functions are removed. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
| * | | ftrace: Remove unused function ftrace_arch_read_dyn_info()Steven Rostedt (VMware)2017-06-271-18/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ftrace_arch_read_dyn_info() was used so that archs could add its own debug information into the dyn_ftrace_total_info in the tracefs file system. That file is for debugging usage of dynamic ftrace. No arch uses that function anymore, so just get rid of it. This also allows for tracing_read_dyn_info() to be cleaned up a bit.

| * | | sh/ftrace: Remove only user of ftrace_arch_read_dyn_info()Steven Rostedt2017-06-271-18/+0

That was used a while ago during the NMI updating in x86, and superh copied it to implement its version of handling NMIs during stop_machine(). But that is a debug feature, and this code hasn't been touched since 2009. Also, x86 no longer does the ftrace updates with stop_machine() and instead uses breakpoints. If superh needs to modify its code, it should implement the breakpoint conversion, and remove stop_machine(). Which also gets rid of the NMI issue. Anyway, I want to nuke ftrace_arch_read_dyn_info() and this gets rid of the one user, which is for an arch that shouldn't need it anymore.

| * | | ftrace: Have cached module filters be an active filterSteven Rostedt (VMware)2017-06-263-6/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a module filter is added to set_ftrace_filter, if the module is not loaded, it is cached. This should be considered an active filter, and function tracing should be filtered by this. That is, if a cached module filter is the only filter set, then no function tracing should be happening, as all the functions available will be filtered out. This makes sense, as the reason to add a cached module filter, is to trace the module when you load it. There shouldn't be any other tracing happening until then.

| * | | tracing: define TRACE_DEFINE_SIZEOF() macro to map sizeof's to their valuesJeremy Linton2017-06-132-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Perf has a problem that if sizeof() macros are used within TRACE_EVENT() macro's they end up in userspace as "sizeof(kernel structure)" which cannot properly be parsed. Add a macro which can forward this data through the eval_map for userspace utilization.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The enum_replace stanza works as is for sizeof() calls as well as enums. Rename it as well.
