[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

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 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

   0.000875000 seconds user
   0.000000000 seconds sys
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:

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.

      !276 support set/get VxLAN rule of rx flow director by ethtool · b683f7f9
      由 openeuler-ci-bot 提交于 
      Merge Pull Request from: @svishen 
 
Background:
Currently, the HNS3 driver, Linux kernel, and standard tools do not support the configuration of VXLAN tunnel tuple information as the key of the flow table. The ethtool –U command supports only the configuration of tuples for non-tunnel packets. Two types of tuples, vxlan4 and vxlan6, need to be added.

Functions:
The vxlan4 and vxlan6 flow types are added to the ethtool –U command. The vni in the outer header and the source MAC address, destination MAC address, source IP address, destination IP address, and VLAN ID in the inner header can be configured as tuple information. The HNS3 driver supports all tuple configurations of both types.

patch name:
(1) net: ethtool: add VxLAN to the NFC API
(2) net: hns3: support set/get VxLAN rule of rx flow director by ethtool


In include/uapi/linux/ethtool.h
We changed a union, but didn't change its size.Neither of the two newly added members exceeds 52 bytes.

The impact on user-mode tools is as follows:
(1)The new tool is compiled on the old kernel and can configure the old flow table. The old kernel does not support VXLAN configuration.

      由 openeuler-ci-bot 提交于 
      Merge Pull Request from: @lujialin2 
 
In cgroupv1, cgroup writeback is not supported for two problems:
1) Blkcg_css and memcg_css are mounted on different cgroup trees. Therefore, blkcg_css cannot be found according to a certain memcg_css.
2) Buffer I/O is worked by kthread, which is in the root_blkcg. Therefore, blkcg cannot limit wbps and wiops of buffer I/O.
We solve the two problems and support cgroup writeback on cgroupv1.
CONFIG: CONFIG_CGROUP_V1_WRITEBACK
startup params: cgroup1_writeback
If someone want to support cgroup writeback in cgroupv1, turn on CONFIG_CGROUP_V1_WRITEBACK; add cgroup1_writeback;mount memcg and blkcg on cgroupv1;
If someone want to attach a cerntain blkcg to a memcg, just echo the inode of the blkcg into memory_wb_blkcg_ino of memcg.

      Merge Pull Request from: @Linwang_68f8 
 
 **Content:** 
Intel® Advanced Matrix Extensions (Intel® AMX) is a new 64-bit programming paradigm consisting of two components: a set of 2-dimensional registers (tiles) representing sub-arrays from a larger 2-dimensional memory image, and an accelerator able to operate on tiles, the first implementation is called TMUL (tile matrix multiply unit).

There are 37 patches in total in this patch set to introduce AMX guest support in openEuler.

 **Intel-kernel issue:** 
https://gitee.com/openeuler/intel-kernel/issues/I5RQLJ

 **Test environment:** 
Host: openEuler 22.09 + backporting kernel
Guest: openEuler 22.09 + QEMU 7.0 + backporting kernel

 **Test cases:** 
Host:
kernel self-test including sigaltstack and AMX state management testing.
TMUL functional testing.
AMX stress.
Context switch testing.
INT8/BF16 online inference.
Guest:
AMX stress.
Context switch testing.
INT8/BF16 online inference.

 **Known issue:** 
N/A

 **Default config change:** 
N/A
