tracing: Move syscalls metadata handling from arch to core

2009-10-14T07:53:56+00:00

Most of the syscalls metadata processing is done from arch.
But these operations are mostly generic accross archs. Especially now
that we have a common variable name that expresses the number of
syscalls supported by an arch: NR_syscalls, the only remaining bits
that need to reside in arch is the syscall nr to addr translation.

v2: Compare syscalls symbols only after the "sys" prefix so that we
    avoid spurious mismatches with archs that have syscalls wrappers,
    in which case syscalls symbols have "SyS" prefixed aliases.

tracing: Ftrace dynamic ftrace_event_call support

2009-08-26T22:46:40+00:00

Add dynamic ftrace_event_call support to ftrace. Trace engines can add
new ftrace_event_call to ftrace on the fly. Each operator function of
the call takes an ftrace_event_call data structure as an argument,
because these functions may be shared among several ftrace_event_calls.

Changes from v13:
 - Define remove_subsystem_dir() always (revirt a2ca5e03), because
   trace_remove_event_call() uses it.
 - Modify syscall tracer because of ftrace_event_call change.

tracing: Create generic syscall TRACE_EVENTs

2009-08-25T22:41:48+00:00

This converts the syscall_enter/exit tracepoints into TRACE_EVENTs, so
you can have generic ftrace events that capture all system calls with
arguments and return values.  These generic events are also renamed to
sys_enter/exit, so they're more closely aligned to the specific
sys_enter_foo events.
