| * Ensure tracepoints are synchronized after unregJosh Stone2009-03-061-0/+4
| | | | | | | | | | | | | | | | | | | | The tracepoint API provides tracepoint_synchronize_unregister() as a way to guarantee that all tracepoint handlers are inactive. This is necessary after unregistering to allow the module to safely unload. * tapsets.cxx (tracepoint_derived_probe_group::emit_module_init): Call synchronize after unregistering tracepoints. (tracepoint_derived_probe_group::emit_module_exit): Ditto.
| * Support older tracepoints using DEFINE_TRACEJosh Stone2009-03-061-0/+5
| | | | | | | | | | | | | | | | | | At one point, the tracepoints API didn't have DECLARE_TRACE, and the trace headers all used DEFINE_TRACE. This is what got pulled into RHEL, so we need to support this older usage. The rest of the API stays the same though. * buildrun.cxx (make_tracequery): Redefine DEFINE_TRACE as well.
| * Enable tracepoint target variablesJosh Stone2009-03-061-3/+338
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses a similar mechanism as marker probes for storing target variables in locals of the probe body. * tapsets.cxx (tracepoint_arg): Add fields to help $target access. (tracepoint_var_expanding_visitor): Expand code to access target variables - a $target for each tracepoint parameter, as well as the special $$name and $$vars. (tracepoint_derived_probe::tracepoint_derived_probe): Expand targets (resolve_tracepoint_arg_type): Determine if a parameter is a type that we can dereference, and store the underlying type. (tracepoint_derived_probe::build_args): Resolve the types. (tracepoint_derived_probe::emit_probe_context_vars): Emit $target placeholders into the locals of the probe body. (tracepoint_derived_probe_group::emit_module_decls): Initialize $targets from the entry point parameters.
| * Emit code to hook up tracepoint probesJosh Stone2009-03-061-4/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * tapsets.cxx (tracepoint_arg): New (tracepoint_derived_probe): Add declaring header name and arg vector (dwarf_type_name): Build a type string for a given type DIE (tracepoint_derived_probe::build_args): Scan the function DIE for the name and type of formal parameters required by the tracepoint. (tracepoint_derived_probe::tracepoint_derived_probe): Call build_args and determine the relevant header to include. (tracepoint_derived_probe_group::emit_module_decls): For each tracepoint, include its header and declare a probe entry point with the right function signature. (tracepoint_derived_probe_group::emit_module_init): Call the registration for each tracepoint, and handle error unwinding. (tracepoint_derived_probe_group::emit_module_exit): Unregister each.
| * Build skeleton tracepoint probesJosh Stone2009-03-061-4/+79
| | | | | | | | | | | | * tapsets.cxx (tracepoint_derived_probe): Create a skeleton probe (tracepoint_derived_probe_group): Create a skeleton group (tracepoint_query::handle_query_func): build a probe
| * Scan tracequery.ko for tracepointsJosh Stone2009-03-061-1/+79
| | | | | | | | | | | | | | * tapsets.cxx (tracepoint_query): Iterate over the modules, CUs, and functions in tracequery.ko looking for our hijacked tracepoint declarations. (tracepoint_builder::build): Run a tracepoint_query
| * Build tracequery to scan for tracepointsJosh Stone2009-03-064-0/+155
| | | | | | | | | | | | | | | | | | | | * session.h (systemtap_session): add tracepoint_derived_probes * buildrun.cxx (make_tracequery): New - builds a kernel module that hijacks the tracepoint declarations, so we can query debuginfo. * buildrun.h: declare above * tapsets.cxx (tracepoint_builder): New builder for tracepoint probes. For now it just handles the initialization to build the tracequery kernel module.
| * Make iterate_over_functions work with base_querysJosh Stone2009-03-061-14/+17
| | | | | | | | | | | | | | | | | | | | * tapsets.cxx (dwflpp::iterate_over_functions): Change arg from void* to base_query*, and add explicit function-search parameters. (query_cu): update caller (query_dwarf_func): update callback signature (Note: instead of passing around callback functions, it might be nicer to use a virtual method in base_query...)
| * Make session.module_cache init more consistentlyJosh Stone2009-03-041-7/+3
| | | | | | | | | | | | | | | | | | We used to check & init module_cache in a few inconsistent places. Now it is always handled in dwflpp::setup_user/setup_kernel. * tapsets.cxx (dwflpp::setup_user): add module_cache check (dwarf_builder::build): remove module_cache check (dwarf_cast_expanding_visitor::visit_cast_op): ditto

| | * Add a testcase for gtod init/killJosh Stone2009-02-231-0/+29
| | | | | | | | | | | | | | | | | | This test simply checks that _gettimeofday_init and _gettimeofday_kill are pulled in when gettimeofday is used, and also that they are NOT pulled in when gettimeofday is not used.
| | * Add selective use of _stp_time_init/kill (PR9822)Josh Stone2009-02-234-50/+75
| | | | | | | | | | | | | | | | | | | | | | | | Our gettimeofday runtime has frequent wakeups to stay in sync with kernel time, but this is wasted effort if gettimeofday is not used in the script. This patch moves the calls to _stp_time_init and _stp_time_kill into begin and end/error probes, which only get pulled in if one of the gettimeofday variants is called.
