[Description]
We try to implement a live-patch mechanism in the userspace based on the UPROBE.
In the handler, we may change the PC register.
In this case, UPROBE must skip the handle of the next instruction.

[Testing]
kernel options:
UPROBES_SUPPORT_PC_ALTER=y

      !268 [OLK-5.10]perf arm64 metricgroup support and some bugfix · 1ec4733f
      由 openeuler-ci-bot 提交于 
      Merge Pull Request from: @liujie-248683921 
 
This series contains support to get basic metricgroups working for
arm64 CPUs.

Initial support is added for HiSilicon hip08 platform.

Some sample usage on Huawei D06 board:

$ ./perf list metric

List of pre-defined events (to be used in -e):

Metrics:

bp_misp_flush
[BP misp flush L3 topdown metric]
branch_mispredicts
[Branch mispredicts L2 topdown metric]
core_bound
[Core bound L2 topdown metric]
divider
[Divider L3 topdown metric]
exe_ports_util
[EXE ports util L3 topdown metric]
fetch_bandwidth_bound
[Fetch bandwidth bound L2 topdown metric]
fetch_latency_bound
[Fetch latency bound L2 topdown metric]
fsu_stall
[FSU stall L3 topdown metric]
idle_by_icache_miss

$ sudo ./perf stat -v -M core_bound sleep 1
Using CPUID 0x00000000480fd010

   0.000875000 seconds user

perf stat --topdown is not supported, as this requires the CPU PMU to
expose (alias) events for the TopDown L1 metrics from sysfs, which arm
does not do. To get that to work, we probably need to make perf use the
pmu-events cpumap to learn about those alias events.

Metric reuse support is added for pmu-events parse metric testcase.
This had been broken on power9 recently:

Differences to v2:

Add TB and RB tags (Thanks!)
Rename metricgroup__find_metric() from metricgroup_find_metric()
Change resolve_metric_simple() to rescan after any insert
Differences to v1:

Add pmu_events_map__find() as arm64-specific function
Fix metric reuse for pmu-events parse metric testcase
John Garry (6):
perf metricgroup: Make find_metric() public with name change
perf test: Handle metric reuse in pmu-events parsing test
perf pmu: Add pmu_events_map__find()
perf vendor events arm64: Add Hisi hip08 L1 metrics
perf vendor events arm64: Add Hisi hip08 L2 metrics
perf vendor events arm64: Add Hisi hip08 L3 metrics

Bugfix：perf vendor events arm64: Fix incorrect metrics and improve readability
First fix the incorrect hip08 metrics, then add some core events to the
JSON file. Last, change the event code to the event name for improving
readability.
changes in v2:
- adjust commit msg of 1st patch.
- fix tab in 3rd patch.

Fibre Channel has been the standard connection type for storage area networks (SAN) in enterprise storage. Despite its name, Fibre Channel signaling can run on both twisted pair copper wire and fiber-optic cables.

The FibreChannel Gen7 adapter supports 64G link speeds. Add debug print support to the driver.
