If PYLINT=1 is passed to the build then run pylint over python code in

6dad43bb11 perf vendor events riscv: Add SiFive P650 events 
The SiFive Performance P650 core (including the vector-enabled P670 and
area-optimized P450/P470 variants) updates the P550 microarchitecture.
It brings in the debug, trace, and counter events from newer Bullet
cores, and adds new events for iTLB and dTLB multi-hits.

All other PMU events are unchanged from the P550 core.

bits wide, but there is no need to keep leading zeroes in the JSON

regenerates the files in a way that does not include leading zeroes.

This change was performed automatically with `sed -i "s/0x0*/0x/"`.

2ed0e3ea8a perf vendor events arm64: Fix incorrect CPU_CYCLE in metrics expr 
Some existing metrics for Neoverse N3 and V3 expressions use CPU_CYCLE
to represent the number of cycles, but this is incorrect. The correct
event to use is CPU_CYCLES.

I encountered this issue while working on a patch to add pmu events for
Cortex A720 and A520 by reusing the existing patch for Neoverse N3 and
V3 by James Clark [1] and my check script [2] reported this issue.

pmu_2. Add or rename matching functions on PMU to make it clearer what
kind of matching is being performed.

  * Scale some metrics like dtlb_walk_ratio to percent so they display
    better with Perf's 2 dp precision
  * Description typos, grammar and clarifications
  * Unnecessary metric formula brackets seem to have been removed in the
    source but this is not a functional change
  * New sve_all_percentage metric

8f997865ee perf pmu: Move pmu_metrics_table__find and remove ARM override 
Move pmu_metrics_table__find() to the jevents.py generated pmu-events.c
and remove indirection override for ARM.

The movement removes perf_pmu__find_metrics_table that exists to enable
the ARM override.

The ARM override isn't necessary as just the CPUID, not PMU, is used in
the metric table lookup.

On non-ARM the CPU argument is just ignored for the CPUID, for ARM -1 is
passed so that the CPUID for the first logical CPU is read.

494c403ff1 perf header: Pass a perf_cpu rather than a PMU to get_cpuid_str 
On ARM the cpuid is dependent on the core type of the CPU in
question. The PMU was passed for the sake of the CPU map but this
means in places a temporary PMU is created just to pass a CPU
value. Just pass the CPU and fix up the callers.

As there are no longer PMU users in header.h, shuffle forward
declarations earlier to work around build failures.

4a159e6049 perf jevents: fix breakage when do perf stat on system metric 
When do perf stat on sys metric, perf tool output nothing now:

  $ perf stat -a -M imx95_ddr_read.all -I 1000
  $

This command runs on an arm64 machine and the Soc has one DDR hw pmu
except one armv8_cortex_a55 pmu. Their maps show as follows:

const struct pmu_events_map pmu_events_map[] = {
{
	.arch = "arm64",
	.cpuid = "0x00000000410fd050",
	.event_table = {
		.pmus = pmu_events__arm_cortex_a55,
		.num_pmus = ARRAY_SIZE(pmu_events__arm_cortex_a55)
	},
	.metric_table = {
		.pmus = NULL,
		.num_pmus = 0
	}
},

static const struct pmu_sys_events pmu_sys_event_tables[] = {
{
	.event_table = {
		.pmus = pmu_events__freescale_imx95_sys,
		.num_pmus = ARRAY_SIZE(pmu_events__freescale_imx95_sys)
	},
	.metric_table = {
		.pmus = pmu_metrics__freescale_imx95_sys,
		.num_pmus = ARRAY_SIZE(pmu_metrics__freescale_imx95_sys)
	},
	.name = "pmu_events__freescale_imx95_sys",
},

Currently, pmu_metrics_table__find() will return NULL when only do perf
stat on sys metric. Then parse_groups() will never be called to parse
sys metric_name, finally perf tool will exit directly. This should be a
common problem.

To fix the issue, this will keep the logic before commit f20c15d13f
("perf pmu-events: Remember the perf_events_map for a PMU") to return a
empty metric table rather than a NULL pointer.

This should be fine since the removed part just check if the table match
provided metric_name.  Without these code, the code in parse_groups()
will also check the validity of metrci_name too.

Fixes: f20c15d13f ("perf pmu-events: Remember the perf_events_map for a PMU")

46610ba41e perf vendor events amd: Update Zen 5 data cache fill events 
For events that count data cache fills, some combinations of the unit
mask bits are useful for counting fills from local caches, DRAM or any
far sources. However, named events currently exist for PMCx044 (Any Data
Cache Fills) only. Add similar events for the following base events.
  * PMCx043 (Demand Data Cache Fills)
  * PMCx059 (Software Prefetch Data Cache Fills)
  * PMCx05A (Hardware Prefetch Data Cache Fills)

While at it, remove "ls_any_fills_from_sys.all_dram_io" since it is a
duplicate of "ls_any_fills_from_sys.dram_io_all".

Event descriptions can be found in Section 2.1.16.5.2 "Load/Store (LS)
Events" of the Processor Programming Reference (PPR) for AMD Family 1Ah
Model 02h Revision C1 Processors document available at the link below.
