In 1d55e8ef34 ("perf tools: Introduce opt_event_config nonterminal") I
removed the unconditional "'/' '/'" for pmu events such as
"intel_pt//" but forgot to use opt_event_config where it expected some
event_config, oops. Fix it.
Noticed when trying to use:
# perf record -e intel_pt// -a sleep 1
event syntax error: 'intel_pt//'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
-e, --event <event> event selector. use 'perf list' to list available events

In hierarchy mode, a filter can affect periods of entries in upper
hierarchy. So it needs to resort the hists after filter.
For example, let's look at following example:
Overhead Command / Shared Object / Symbol
------------ --------------------------------
30.00% perf
20.00% perf
10.00% main
5.00% pr_debug
5.00% memcpy
10.00% [kernel.vmlinux]
8.00% memset
2.00% cpu_idle
If we apply simbol filter for 'mem' it should look like this
13.00% perf
8.00% [kernel.vmlinux]
8.00% memset
5.00% perf
5.00% memcpy

The hists__filter_hierarchy() function implements filtering in hierarchy
mode. Now we have hist_entry__filter() so use it for entries in the
hierarchy. It returns 3 kind of values.
A negative value means that it's not filtered by this type. It marks
current entry as filtered tentatively so if a lower level entry removes
the filter it also removes the all parent so that we can find the entry
in the output.
Zero means it's filtered out by this type. A positive value means it's
not filtered so it removes the filter and shows in the output. In these
cases, it moves to next entry since lower level entry won't match by
this type of filter anymore. Thus all children will be filtered or not
together.

The hist_entry__filter() function is to filter hist entries using sort
key related info. This is needed to support hierarchy mode since each
hist entry will be associated with a hpp fmt which has a sort key. So
each entry should compare to only matching type of filters.
To do that, add the ->se_filter callback field to struct sort_entry.
This callback takes 'type' argument which determines whether it's
matching sort key or not. It returns -1 for non-matching type, 0 for
filtered entry and 1 for not filtered entries.

The rb_hierarchy_{next,prev,last} functions are to traverse all hist
entries in a hierarchy. They will be used by various function which
supports hierarchy output.
As the rb_hierarchy_next() is used to traverse the whole hierarchy, it
sometime needs to visit entries regardless of current folding state. So
add enum hierarchy_move_dir and pass it to __rb_hierarchy_next() for
those cases.

For hierarchical output, each entry must be sorted in their rbtree
(hroot) properly. Add hists__hierarchy_output_resort() to do the job.
Note that those hierarchy entries share the period counts, it'd be
important to update the hists->stats only once (for leaves).

In the hierarchical view, entries will be grouped and sorted on the
first key, and then on the second key, and so on. Add the
he->hroot_{in,out} fields to keep the lower level entries. Actually this
can share space, in a union, with callchain's 'sorted_root' since the
hroots are only used by non-leaf entries and callchain is only used by
leaf entries.
It also adds the 'parent_he' and 'depth' fields which can be used by browsers.
This patch only implements collapsing part which creates internal
entries for each sort key. These need to be sorted by output_sort stage
and to be displayed properly in the later patch(es).

Merge tag 'perf-core-for-mingo-2' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
New features:
- Add API to set values of map entries in a BPF object, be it
individual map slots or ranges (Wang Nan)
- Introduce support for the 'bpf-output' event (Wang Nan)

'perf script' (Jiri Olsa)
Infrastructure changes:
- Export cacheline routines (Jiri Olsa)

When an error happens during alias parsing currently the complete
parsing of all attributes of the PMU is stopped. This is breaks old perf
on a newer kernel that may have not-yet-know alias attributes (such as
.scale or .per-pkg).
Continue when some attribute is unparseable.
This is IMHO a stable candidate and should be backported to older
versions to avoid problems with newer kernels.
v2: Print warnings when something goes wrong.
v3: Change warning to debug output

Adding -e option for perf mem record command, to be able to specify
memory event directly.
Get list of available events:
$ perf mem record -e list
ldlat-loads
ldlat-stores
Monitor ldlat-loads:
$ perf mem record -e ldlat-loads true
Committer notes:
Further testing:
# perf mem record -e ldlat-loads true
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.020 MB perf.data (10 samples) ]
# perf evlist
cpu/mem-loads,ldlat=30/P

The operation '%' is not implemented on event-parse.c, causing an error
when parsing events with '%' the operation in its printk format. For
example,
# perf record -e sched:sched_deadline_yield ~/yield-test
Warning: [sched:sched_deadline_yield] unknown op '%'
....
# perf script
Warning: [sched:sched_deadline_yield] unknown op '%'
test 1641 [006] 3364.109319: sched:sched_deadline_yield: \
[FAILED TO PARSE] now=3364109314595 \
deadline=3364139295135 runtime=19975597
This patch implements the '%' operation. With this patch, we see the
correct output:
# perf record -e sched:sched_deadline_yield ~/yield-test
No Warning
# perf script
yield-test 4005 [001] 4623.650978: sched:sched_deadline_yield: \
now=4623.650974050 \

Users can pass options to tracepoints defined in the BPF script. For
example:
# perf record -e ./test.c/no-inherit/ bash
# dd if=/dev/zero of=/dev/null count=10000
# exit
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.022 MB perf.data (139 samples) ]
(no-inherit works, only the sys_read issued by bash are captured, at
least 10000 sys_read issued by dd are skipped.)
test.c:
#define SEC(NAME) __attribute__((section(NAME), used))
SEC("func=sys_read")
int bpf_func__sys_read(void *ctx)
{
return 1;
}
char _license[] SEC("license") = "GPL";
int _version SEC("version") = LINUX_VERSION_CODE;
no-inherit is applied to the kprobe event defined in test.c.
