Removing attr_offset from perf_header as it's possible to use it as a local variable. Signed-off-by:

If an user gives both of --symfs and --vmlinux option, the vmlinux will be searched under the symfs directory. This is somewhat confusing since vmlinux often lives in kernel build directory or somewhere other than user space binaries. So it'd be better not adding symfs prefix for a vmlinux if it has an absolute pathname. Reported-by:

Boris just raised another variant of building perf tools which is broken: $ make tools/perf ... LINK /home/robert/cx/linux/tools/perf/perf gcc: error: ../linux/tools/lib/lk/liblk.a: No such file or directory The variant wasn't considered by: 107de372 perf tools: Fix build errors with O and DESTDIR make vars set There are other variant of building perf too: $ make -C tools perf $ make -C tools/perf Plus variants with O= and DESTDIR set. This patch fixes the above and was tested with the following: $ make O=... DESTDIR=... tools/perf $ make O=... DESTDIR=... -C tools/ perf $ make O=... DESTDIR=... -C tools/perf $ make tools/perf $ make -C tools/ perf $ make -C tools/perf Reported-by:Borislav Petkov <bp@alien8.de> Signed-off-by:

Removing event types framework completely. The only remainder (apart from few comments) is following enum: enum perf_user_event_type { ... PERF_RECORD_HEADER_EVENT_TYPE = 65, /* deprecated */ ... } It's kept as deprecated, resulting in error when processed in perf_session__process_user_event function. Signed-off-by: -

Removing event types data storing/reading to/from perf data file as it's no longer needed. The only user of this data 'perf timechart' was switched to use tracepoints handler callbacks. The event_types offset and size stay in the perf data file header but are ignored from now on. Signed-off-by:

Jiri Olsa authored
The only user of the event types data is 'perf timechart' command and uses this info to identify proper tracepoints based on its name. Switching this code to use tracepoint callbacks handlers same as another commands like builtin-{kmem,lock,sched}.c using the perf_session__set_tracepoints_handlers function. This way we get rid of the only event types user and can remove them completely in next patches. Signed-off-by: -

Adding diff command the flexibility to specify multiple data files on input. If not input file is given the standard behaviour stands and diff inspects 'perf.data' and 'perf.data.old' files. Signed-off-by:

It does not make sense to make some computation (ratio, wdiff), when the hist_entry is 'dummy' - added via hists__link. Adding dummy field to struct hist_entry which indicates that it was added by hists__link and avoiding some of the processing for such entries. Signed-off-by:

Making the baseline hists to act as a pairs head. So far we don't care which hists act as a pairs head, because we have only 2 files to deal with and any of them is suitable to do the job. But if we want to process more files, we need to pick up one hists to act as pairs head, and the baseline hists is the most suitable. Signed-off-by:

Now when diff command is separated from other standard outputs, we can use perf_hpp__init to initialize all standard columns. Moving PERF_HPP__OVERHEAD column init back to perf_hpp__init, and removing extra enable calls. Signed-off-by:

Adding 'struct perf_hpp_fmt' into hpp callbacks, so commands can access their private data. It'll be handy for diff command in future to be able to access file related data for each column. Signed-off-by:

For example, in an application with an expensive function implemented with deeply nested recursive calls, the default call-graph presentation is dominated by the different callchains within that function. By ignoring these callees, we can collect the callchains leading into the function and compactly identify what to blame for expensive calls. For example, in this report the callers of garbage_collect() are scattered across the tree: $ perf report -d ruby 2>- | grep -m10 ^[^#]*[a-z] 22.03% ruby [.] gc_mark --- gc_mark |--59.40%-- mark_keyvalue | st_foreach | gc_mark_children | |--99.75%-- rb_gc_mark | | rb_vm_mark | | gc_mark_children | | gc_marks | | |--99.00%-- garbage_collect If we ignore the callees of garbage_collect(), its callers are coalesced: $ perf report --ignore-callees garbage_collect -d ruby 2>- | grep -m10 ^[^#]*[a-z] 72.92% ruby [.] garbage_collect --- garbage_collect vm_xmalloc |--47.08%-- ruby_xmalloc | st_insert2 | rb_hash_aset | |--98.45%-- features_index_add | | rb_provide_feature | | rb_require_safe | | vm_call_method Signed-off-by:Greg Price <price@mit.edu> Tested-by:

When an event fails to parse and it's not in a new style format, try to parse it again as a cpu event. This allows to use sysfs exported events directly without //, so you can use perf record -e mem-loads ... instead of perf record -e cpu/mem-loads/ Signed-off-by:

The 'size' variable includes the header so must be at least 'sizeof(struct perf_event_header)'. Error out immediately if that is not the case. Also don't byte-swap the header until it is actually "fetched" from the mmap region. Signed-off-by:

The 'rules' means that every second line of the tree view has a shaded background, which makes it easier to see which cell belongs to which row in the tree view. It can be useful for a tree view that has a lot of rows. Reviewed-by:
