When we disable a breakpoint through dr7, we unregister it right away, making us lose track of its corresponding address register value. It means that the following sequence would be unsupported: - set address in dr0 - enable it through dr7 - disable it through dr7 - enable it through dr7 because we lost the address register value when we disabled the breakpoint. Don't unregister the disabled breakpoints but rather disable them. Reported-by:

The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook style comments that used to live with 'TRACE_EVENT()' are now moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook system understand the new 'DEFINE_EVENT()' macro. In addition I've tried to futureproof the patch, by also adding support for 'DEFINE_SINGLE_EVENT()', since there has been discussion about renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT(). Without this patch the tracepoint docbook fails to build. I've verified that this patch correctly builds the tracepoint docbook which currently covers signals, and irqs. Changes in v2: - properly indent perl 'if' statements Signed-off-by:

Add --list option for listing currently defined probe events in the kernel. This shows events in below format; [group:event] <perf-probe probe-definition> for example: [probe:schedule_0] schedule+30 cpu Note that source file/line information is not supported yet. So even if you added a probe by line, it will be shown in <symbol+offset>. Signed-off-by:

Tom Zanussi authored
The debugging versions of the ENTER and LEAVE internal perl macros, used when embedding perl, define a local block with a my_perl perl variable that shadows a global variable of the same name, which is also the name expected by the embedding API for the embedded interpreter. Since we don't have control over the code generated in this case (it's an externality) and can't get rid of the warning, ignore it. Signed-off-by:

To capture the relevant events for a given Perl script and to avoid having to continually remember and type in long command-lines, add a scripts/perl/bin directory containing two simple shell scripts for each Perl script, one for recording and one for processing/display. For example, to record perf data for the rw-by-pid.pl script, run scripts/perl/bin/rw-by-pid-record and to actually run the script and display the output run scripts/perl/bin/rw-by-pid-report.

Tom Zanussi authored
The Perl scripting support for perf trace allows most of a trace event's data to be accessed directly as handler arguments, but not all of it e.g. the less common fields aren't passed in. To give scripts access to the other fields and/or any other data or metadata in the main perf executable that might be useful, a way to access the C data in perf from Perl is needed; this patch uses the Perl XS facility to do it for the common_xxx event fields not passed to handler functions. Context.pm exports three functions to Perl scripts that access fields for the current event by calling back into perf: common_pc(), common_flags() and common_lock_depth(). Support for common_flags() field values was added to Core.pm and a script used to sanity check these and other basic scripting features, check-perf-trace.pl, was also added. Signed-off-by:

Add Perf-Trace-Util Perl module and some scripts that use it. Core.pm contains Perl code to define and access flag and symbolic fields. Util.pm contains general-purpose utility functions. Also adds some makefile bits to install them in libexec/perf-core/scripts/perl (or wherever perfexec_instdir points). Signed-off-by:

Implement trace_scripting_ops to make Perl a supported perf trace scripting language. Additionally adds code that allows Perl trace scripts to access the 'flag' and 'symbolic' (__print_flags(), __print_symbolic()) field information parsed from the trace format files. Also adds the Perl implementation of the generate_script() trace_scripting_op, which creates a ready-to-run perf trace Perl script based on existing trace data. Scripts generated by this implementation print out all the fields for each event mentioned in perf.data (and will detect and generate the proper scripting code for 'flag' and 'symbolic' fields), and will additionally generate handlers for the special 'trace_unhandled', 'trace_begin' and 'trace_end' handlers. Script authors can simply remove the printing code to implement their own custom event handling. Signed-off-by:
