2014-12-19tools/liblockdep: Fix debug_check thinko in mutex destroyKirill Smelkov1-2/+2
In mutex destroy code currently we pass to debug_check_no_locks_freed() [mem_from, mem_end) address region. But debug_check_no_locks_freed() accepts mem_from, mem_*len* i.e. second parameter is region length, not end address. And it was always so, starting from 2006 (fbb9ce95 "lockdep: core"). Fix it, or else on a mutex destroy we wrongly check much-wider-than-mutex region and can find not-yet-released other locks there and wrongly report BUGs on them.

2014-09-25tools lib fd array: Allow associating an integer cookie with each entryArnaldo Carvalho de Melo2-5/+39
We will use this in perf's evlist class so that it can, at fdarray__filter() time, to unmap the associated ring buffer. We may need to have further info associated with each fdarray entry, in that case we'll make that int array a 'union fdarray_priv' one and put a pointer there so that users can stash whatever they want there. For now, an int is enough tho. v2: Add clarification to the per array entry priv area, as well as make it a union, which makes usage a bit longer, but if/when we make it use more space by allowing per entry pointers existing users source code will not have to be changed, just rebuilt.

2014-06-08tools lib traceevent: Added support for __get_bitmask() macroSteven Rostedt (Red Hat)2-0/+120
Coming in v3.16, trace events will be able to save bitmasks in raw format in the ring buffer and output it with the __get_bitmask() macro. In order for userspace tools to parse this, it must be able to handle the __get_bitmask() call and be able to convert the data that's in the ring buffer into a nice bitmask format. The output is similar to what the kernel uses to print bitmasks, with a comma separator every 4 bytes (8 characters). This allows for cpumasks to also be saved efficiently. The first user is the thermal:thermal_power_limit event which has the following output: thermal_power_limit: cpus=0000000f freq=1900000 cdev_state=0 power=5252 Link: http://lkml.kernel.org/r/20140506132238.22e136d1@gandalf.local.home Suggested-by: Javi Merino <javi.merino@arm.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Javi Merino <javi.merino@arm.com> Link: http://lkml.kernel.org/r/20140603032224.229186537@goodmis.org Signed-off-by: Jiri Olsa <jolsa@kernel.org>

2014-06-08tools lib traceevent: Add options to pluginsSteven Rostedt2-3/+209
The traceevent plugins allows developers to have their events print out information that is more advanced than what can be achieved by the trace event format files. As these plugins are used on the userspace side of the tracing tools, it is only logical that the tools should be able to produce different types of output for the events. The types of events still need to be defined by the plugins thus we need a way to pass information from the tool to the plugin to specify what type of information to be shown. Not only does the information need to be passed by the tool to plugin, but the plugin also requires a way to notify the tool of what options it can provide. This builds the plugin option infrastructure that is taken from trace-cmd that is used to allow plugins to produce different output based on the options specified by the tool.

2014-04-23tools lib traceevent: Fix memory leak in pretty_print()Steven Rostedt1-0/+1
Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.

2014-04-23tools lib traceevent: Fix backward compatibility macros for pevent filter enumsSteven Rostedt1-2/+2
The return value for pevent_filter_match() is suppose to return FILTER_NONE if the event doesn't have a filter, and FILTER_NOEXIST if there is no filter at all. But the change 41e12e580a7 "tools lib traceevent: Refactor pevent_filter_match() to get rid of die()" replaced the return value with PEVENT_ERRNO__* values and added "backward compatibility" macros that used the old names. Unfortunately, the NOEXIST and NONE macros were swapped, and this broke users that use the old return names.

2014-04-14tools lib traceevent: Do not call warning() directlyNamhyung Kim1-2/+4
The patch 3a3ffa2e82205 ("tools lib traceevent: Report better error message on bad function args") added the error message but it seems there's no reason to call warning() directly. So change it to do_warning_event() to provide event information too.

2014-04-14tools lib traceevent: Print event name when show warning if possibleNamhyung Kim1-41/+62
It's sometimes useful to know where the parse failure was occurred. Add do_warning_event() macro to see the failing event. It now shows the messages like below: $ perf test 5 5: parse events tests : Warning: [kvmmmu:kvm_mmu_get_page] bad op token { Warning: [kvmmmu:kvm_mmu_sync_page] bad op token { Warning: [kvmmmu:kvm_mmu_unsync_page] bad op token { Warning: [kvmmmu:kvm_mmu_prepare_zap_page] bad op token { Warning: [kvmmmu:fast_page_fault] function is_writable_pte not defined Warning: [xen:xen_mmu_ptep_modify_prot_commit] function sizeof not defined Warning: [xen:xen_mmu_ptep_modify_prot_start] function sizeof not defined Warning: [xen:xen_mmu_set_pgd] function sizeof not defined Warning: [xen:xen_mmu_set_pud] function sizeof not defined Warning: [xen:xen_mmu_set_pmd] function sizeof not defined ...
