| | | | | | | | | | | | | | | * stack.c: Reorganize and split arch-specific functions to separate files. (_stp_kta): Better checking. (_stp_stack_sprint): Better handling of return probes. * stack-i386.c: New file. Uses 2.6.18 DWARF unwinder if available. * stack-x86_64.c: New file. Uses 2.6.18 DWARF unwinder if available. * stack-ppc64.c: New file. * stack-ia64.c: New file. * sym.c (_stp_kallsyms_lookup_name): New function. Like kallsyms_lookup_name() except use our internal lookup table.
* * ioscheduler.stp:guanglei2006-10-126-112/+119
| | | | | | | | | | | bugfix to avoid refer to NULL pointer * hookid_defs.stp, ioscheduler.stp, register_event.stp: break the old addevent.ioscheduler.elv_next_request into addevent.ioscheduler.elv_next_request.entry and addevent.ioscheduler.elv_next_request.return. Now log_ioscheduler_tracedata_* will use the variables defined in generic ioscheduler tapset

| | | | | | | | | | | | | | * tapsets.cxx (in_kprobes_function): New function that looks up the values of '__kprobes_text_start' and '__kprobes_text_end' in the kernel to be able to automatically exclude functions marked as '__kprobes' (BZ# 2639). (blacklisted_p): Calls in_kprobes_function(). (query_kernel_module): Utility function that finds the kernel module. * session.h (struct systemtap_session): Added kprobes_text variables - kprobes_text_initialized, kprobes_text_start, and kprobes_text_end. * elaborate.cxx (systemtap_session::systemtap_session): kprobes_text variables get initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | document signal syscall hookiddefs.stp: some changes to the hookid: Now the hookid of a return type event(addevent.*.return) should be an even number and its value should be the corresponding entry event hookid +1. The hookid of a non-return type event should be an odd number. Add the hookid of HOOKID_REGEVTDESC register_event.stp: add register_evt_desc() to register the description of an event. Change the register_sys_event() to add the an argument representing event description Allow to use empty format string and empty field name when calling register_event(). Change all calling to register_sys_event() to add an argument which represents the event description. Change register_evt_desc() and register_event() to add an argument representing the event description string, which could help facilitate the error debugging. iosyscall.stp: bugfix to add the variable GroupID and hookID nfs.stp: bugfix to add some omitted probe definitions. nfs_proc.stp: bugfix of the wrong calling to _lket_trace() for nfs_proc.remove.entry.
