Starting on v4.12 event parsing code for dynamic pmu events already
supports prefix-based matching of multiple pmus when creating dynamic
events. E.g., in a system with the following dynamic pmus:
mypmu_0
mypmu_1
mypmu_2
mypmu_4
passing mypmu/<config>/ as an event spec will result in the creation of
the event in all of the pmus. This change expands this matching through
the use of fnmatch so glob-like expressions can be used to create events
in multiple pmus. E.g., in the system described above if a user only
wants to create the event in mypmu_0 and mypmu_1, mypmu_[01]/<config>/
can be passed.

To simplify creation of events accross multiple instances of the same
type of PMU stat supports two methods for creating multiple events from
a single event specification:
1. A prefix or glob can be used in the PMU name.
2. Aliases, which are listed immediately after the Kernel PMU events
by perf list, are used.
When the --no-merge option is passed and these events are displayed
individually the PMU name is lost and it's not possible to see which
count corresponds to which pmu:
$ perf stat -a -e l3cache/read-miss/ --no-merge ls > /dev/null
Performance counter stats for 'system wide':
67 l3cache/read-miss/
67 l3cache/read-miss/
63 l3cache/read-miss/
60 l3cache/read-miss/
0.001675706 seconds time elapsed
$ perf stat -a -e l3cache_read_miss --no-merge ls > /dev/null
Performance counter stats for 'system wide':
12 l3cache_read_miss
17 l3cache_read_miss
10 l3cache_read_miss
8 l3cache_read_miss
0.001661305 seconds time elapsed
This change adds the original pmu name to the event. For dynamic pmu
events the pmu name is restored in the event name:
$ perf stat -a -e l3cache/read-miss/ --no-merge ls > /dev/null
Performance counter stats for 'system wide':
63 l3cache_0_3/read-miss/
74 l3cache_0_1/read-miss/
64 l3cache_0_2/read-miss/
74 l3cache_0_0/read-miss/
0.001675706 seconds time elapsed
For alias events the name is added after the event name:
$ perf stat -a -e l3cache_read_miss --no-merge ls > /dev/null
Performance counter stats for 'system wide':
10 l3cache_read_miss [l3cache_0_3]
12 l3cache_read_miss [l3cache_0_1]
10 l3cache_read_miss [l3cache_0_2]
17 l3cache_read_miss [l3cache_0_0]

Auto-merge for these events was disabled when auto-merging of non-alias
events was disabled in commit 63ce844 (perf stat: Only auto-merge events
that are PMU aliases).
Non-merging of legacy events is preserved:
$ perf stat -ag -e cache-misses,cache-misses sleep 1
Performance counter stats for 'system wide':
86,323 cache-misses
86,323 cache-misses
1.002623307 seconds time elapsed
But prefix or glob matching auto-merges the events created:
$ perf stat -a -e l3cache/read-miss/ sleep 1
Performance counter stats for 'system wide':
328 l3cache/read-miss/
1.002627008 seconds time elapsed
$ perf stat -a -e l3cache_0_[01]/read-miss/ sleep 1
Performance counter stats for 'system wide':
172 l3cache/read-miss/
1.002627008 seconds time elapsed
As with events created with aliases, auto-merging can be suppressed with
the --no-merge option:
$ perf stat -a -e l3cache/read-miss/ --no-merge sleep 1
Performance counter stats for 'system wide':
67 l3cache/read-miss/
67 l3cache/read-miss/
