| | * Document TRACEPOINTS in stapprobes(5)Josh Stone2009-03-061-0/+36
| | |
| | * 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
