In dso__load(), it checks if the dso is a kernel module by looking the
symtab type. Actually dso has 'is_kmod' field to check that easily and
dso__set_module_info() set the symtab type and the is_kmod bit. So it
should have the same result to check the is_kmod bit.

It's expected that both hist entries are in the same hists when
comparing two. But the current code in the function checks one without
dso sort key and other with the key. This would make the condition true
in any case.
I guess the intention of the original commit was to add '!' for the
right side too. But as it should be the same, let's just remove it.

In the previous loop, all the members in the aliases[j-1] have been freed
and set to NULL. But in this loop, the function pmu_alias_is_duplicate()
compares the aliases[j] with the aliases[j-1] that has already been
disposed, so the function will always return false and duplicate aliases
will never be discarded.
If we find duplicate aliases, it skips the zfree aliases[j], which is
accompanied by a memory leak.
We can use the next aliases[j+1] to theck for duplicate aliases to
fixes the aliases NULL pointer dereference, then goto zfree code snippet
to release it.

When using perf timehist, sch delay is only computed for a waking task,
not for a pre empted task. This patches changes sch delay to account for
both. This makes sense as testing scheduling policy need to consider the
effect of scheduling delay globally, not only for waking tasks.
Example of `perf timehist` report before the patch for `stress` task
competing with each other.
First column is wait time, second column sch delay, third column
runtime.
1.492060 [0000] s stress[81] 1.999 0.000 2.000 R next: stress[83]
1.494060 [0000] s stress[83] 2.000 0.000 2.000 R next: stress[81]
1.496060 [0000] s stress[81] 2.000 0.000 2.000 R next: stress[83]
1.498060 [0000] s stress[83] 2.000 0.000 1.999 R next: stress[81]
After the patch, it looks like this (note that all wait time is not zero
anymore):
1.492060 [0000] s stress[81] 1.999 1.999 2.000 R next: stress[83]

JMPABS is 64-bit absolute direct jump instruction, encoded with a mandatory
REX2 prefix. JMPABS is designed to be used in the procedure linkage table
(PLT) to replace indirect jumps, because it has better performance. In that
case the jump target will be amended at run time. To enable Intel PT to
follow the code, a TIP packet is always emitted when JMPABS is traced under
Intel PT.
Refer to the Intel Advanced Performance Extensions (Intel APX) Architecture
Specification for details.
Decode JMPABS as an indirect jump, because it has an associated TIP packet
the same as an indirect jump and the control flow should follow the TIP
packet payload, and not assume it is the same as the on-file object code
JMPABS target address.

Test "perf probe of function from different CU" only checks if the perf
command has failed and doesn't test the --funcs output. In the issue
reported in the previous commit, the garbage output of the --funcs
command was being ignored by the test when it could have been caught.
The script first makes use of --funcs option with the perf probe command
to check if the function "foo" exists in the testfile before adding a
probe to it in the next command. The output of probe...--funcs command
is redirected to stdout, therefore, add '| grep "foo"' to validate the
result.

This patch handles dso's of form "/tmp/perf-$PID.map".
Some of the references doesn't check exactly for same pattern.
some uses "if (!strncmp(dso_name, "/tmp/perf-", 10))". Fix
this by using helper function perf_pid_map_tid and
is_perf_pid_map_name which looks for proper pattern of
form: "/tmp/perf-$PID.map" for these checks.

Perf probe fails to find symbol foo in the executable placed in

# cp test /tmp/perf-checkcWpuLRQI8j/

# ./perf probe -x /tmp/perf-checkcWpuLRQI8j/test foo
Failed to find symbol foo in /tmp/perf-checkcWpuLRQI8j/test
Error: Failed to add events.
But it works with any files like /tmp/perf/test. Only for
patterns with "/tmp/perf-", this fails.
Further debugging, commit 80d496be89ed ("perf report: Add support
for profiling JIT generated code") added support for profiling JIT
generated code. This patch handles dso's of form
"/tmp/perf-$PID.map" .
The check used "if (strncmp(self->name, "/tmp/perf-", 10) == 0)"
to match "/tmp/perf-$PID.map". With this commit, any dso in
/tmp/perf- folder will be considered separately for processing
(not only JIT created map files ). Fix this by changing the
string pattern to check for "/tmp/perf-%d.map". Add a helper
function is_perf_pid_map_name to do this check. In "struct dso",
dso->long_name holds the long name of the dso file. Since the
/tmp/perf-$PID.map check uses the complete name, use dso___long_name for
the string name.
With the fix,

The 2 second sleep can cause the test to fail on very slow network file
systems because Perf ends up being killed before it finishes starting
up.
Fix it by making the leafloop workload end after a fixed time like the
other workloads so there is no need to kill it after 2 seconds.
Also remove the 1 second start sampling delay because it is similarly
fragile. Instead, search through all samples for a matching one, rather
than just checking the first sample and hoping it's in the right place.

Needed to add required include directories for the feature detection
to succeed. The header tracefs.h is installed either into the include
directory /usr/include/tracefs/tracefs.h when using the Makefile, or
into /usr/include/libtracefs/tracefs.h when using meson to build
libtracefs. The header tracefs.h uses #include <event-parse.h> from
libtraceevent, so pkg-config needs to pick the correct include directory
for libtracefs and add the one for libtraceevent to succeed.

Performance counter stats for 'system wide':

The insn per cycle for cpu_core should be 4,268,965 / 9,733,603 = 0.44.
When finding the metric events, the find_stat() doesn't take the PMU
type into account. The cpu_atom/cycles/ is wrongly used to calculate
the IPC of the cpu_core.
In the hard-coded metrics, the events from a different PMU are only
SW_CPU_CLOCK and SW_TASK_CLOCK. They both have the stat type,
STAT_NSECS. Except the SW CLOCK events, check the PMU type as well.
