a91ffcf30e perf tools: Support pmu prefix for mem-store event 
For enabling mem-store event, it doesn't need an auxiliary event.
So just build an event name string with the pmu prefix.

d2f327acc6 perf tools: Support pmu prefix for mem-load event 
The perf_mem_events__name() can generate the mem-load event name.
It uses a variable 'mem_loads_name__init' to avoid generating the
event name every time (because perf_pmu__scan takes some time).

The perf_mem_events__name() assumes the pmu is "cpu" but it's not
correct for hybrid platform. For Alderlake, the pmu is "cpu_core" or
"cpu_atom"

Introduce a new parameter 'pmu_name' in perf_mem_events__name
to let the caller specify a pmu name.

Considering such event name is x86 specific, so move
perf_mem_events[] to arch/x86/util/mem-events.c.

We still keep the variable 'mem_loads_name__init' but it's only
used when pmu_name is NULL (compatible for original behavior). When
pmu_name is not NULL (e.g. "cpu_core"), this patch doesn't have
optimization. That can be implemented in follow up patch.

ddc11da5eb perf tools: Check mem-loads auxiliary event 
For some platforms, an auxiliary event has to be enabled
simultaneously with the load latency event.

For Alderlake, the auxiliary event is created in "cpu_core" pmu.

So first we need to check the existing of "cpu_core" pmu
and then check if this pmu has auxiliary event.

da963834fe perf test: Iterate over shell tests in alphabetical order 
The for_each_shell_test macro iterated over all shell tests in the
directory using readdir, which does not guarantee any ordering, causing
problems on certain fs. However, the order in which they are visited
determines the id of the test, in case one wants to run a single test.

This patch replaces readdir with scandir using alphabetical sorting.
This guarantees that, given the same set of tests, all machines will
see the tests in the same order, and, thus, that test ids are
consistent.

41ca1d1e88 perf probe: Provide more detail with relocation warning 
When run as normal user with default sysctl kernel.kptr_restrict=0
and kernel.perf_event_paranoid=2, perf probe fails with:

  $ ./perf probe move_page_tables
  Relocated base symbol is not found!

The warning message is not much informative. The reason perf fails
is because /proc/kallsyms is restricted by perf_event_paranoid=2
for normal user and thus perf fails to read relocated address of
the base symbol.

Tweaking kptr_restrict and perf_event_paranoid can change the
behavior of perf probe. Also, running as root or privileged user
works too. Add these details in the warning message.

Plus, kmap->ref_reloc_sym might not be always set even if
host_machine is initialized. Above is the example of the same.
Remove that comment.

The option "opts->full_auxtrace" is checked at the earlier place, if it
is false the function will directly bail out.  So remove the redundant

f99237e464 perf arm-spe: Enable timestamp for per-cpu mode 
For per-cpu mmap, it should enable timestamp tracing for Arm SPE; this
is helpful for samples correlation.

To automatically enable the timestamp, a helper arm_spe_set_timestamp()
is introduced for setting "ts_enable" format bit.

e582badf17 perf arm-spe: Correct sample flags for dummy event 
The dummy event is mainly used for mmap, the TIME sample is only needed
for per-cpu case so that the perf tool can rely on the correct timing
for parsing symbols.  And the CPU sample is useless for mmap.

The BRANCH_STACK sample bit will be always reset for the dummy event in
the function evsel__config(), so don't need to repeatedly reset it for
Arm SPE specific.

So this patch only enables TIME sample for per-cpu mmap.

2f02195495 perf arm-spe: Correct sample flags for SPE event 
Now it's hard code to set sample flags for CPU, TIME and TID for SPE
event, which is pointless.

The CPU is useful for sampling only for per-mmap case, it is used to
indicate the AUX trace is associated to which CPU.

The TIME sample is not needed for AUX event, since the time for AUX
event is not really used and this time is a different thing from the
timestamp in Arm SPE trace, the timestamp tracing which is controlled
by Arm SPE's config bit.

The TID sample is not useful for AUX event.

This patch corrects the sample flags for SPE event, it only set CPU
sample bit for per-cpu mmap case.
