[PATCH openEuler-5.10 01/31] timer_list: avoid other cpu soft lockup when printing timer list

---------------------------
If system has many cpus (e.g. 128), it will spend a lot of time to
print message to the console when execute echo q > /proc/sysrq-trigger.
When /proc/sys/kernel/numa_balancing is enabled, if the migration threads
is woke up, the thread cannot continue until the print finish, it will
trigger a soft lockup.

[PATCH openEuler-1.0-LTS 01/13] sched: Introduce qos scheduler for co-location

CVE: NA
--------------------------------
We introduce the idea of qos level to scheduler, which now is
supported with different scheduler policies. The qos scheduler
will change the policy of correlative tasks when the qos level
of a task group is modified with cpu.qos_level cpu cgroup file.
In this way we are able to satisfy different needs of tasks in
different qos levels.

[PATCH openEuler-1.0-LTS 1/3] ACPI: CPPC: Fix cppc_cpufreq_init failed in CPU Hotplug situation

CVE: NA
-------------------------------------------------
Per-CPU variables cpc_desc_ptr are initialized in
acpi_cppc_processor_probe() when the processor devices are present and
added into the system. But when cpu_possible_mask and cpu_present_mask
is not equal, only cpc_desc_ptr in cpu_present_mask are initialized,
this will cause acpi_get_psd_map() failed in cppc_cpufreq_init().
To fix this issue, we parse the _PSD method for all possible CPUs to get
the P-State topology and modify acpi_get_psd_map() to rely on this
information.

[PATCH openEuler-5.10 16/31] perf, kvm/arm64: perf-kvm-stat to report VM TRAP
by Zheng Zengkai 26 Nov '21

bugzilla: https://gitee.com/openeuler/kernel/issues/I4IZPY
CVE: NA
-------------------------------------------------
When guest exits due to "TRAP", we can analyze the guest exit reasons
deeplier. Enhance perf-kvm-stat to record and analyze VM TRAP events.
There is a mapping between guest's "trap_code" (ESR_ELx's bits[31:26])
and "trap_reason" - kvm_arm_exception_class. Copy it from kernel to
aarch64_guest_exits.h, export it to userspace.
This patch records two new KVM tracepoints: "kvm:kvm_trap_enter" and
"kvm:kvm_trap_exit", and reports statistical data between these two
tracepoints.
A simple test go below:
# ./tools/perf/perf kvm stat record -p 20763
[ perf record: Woken up 92 times to write data ]
[ perf record: Captured and wrote 203.727 MB perf.data.guest (2601786 samples) ]
# ./tools/perf/perf kvm stat report --event=vmexit
Analyze events for all VMs, all VCPUs:

Re: [PATCH openEuler-1.0-LTS 1/1] ras: report cpu logical index to userspace in arm event
by Xie XiuQi 25 Nov '21
by Xie XiuQi 25 Nov '21
25 Nov '21
Hi，
这个补丁在 openEuler 20.03 有合入吗？
修改 trace 格式相当于是修改ABI了，为避免与上层应用，如rasdaemon 等存在兼容性问题，
这个在之前版本也是修改过吗？
还有，这个如果是为了增加 cpu logical index，是不是看一看推一下上游社区，免得每个版本
都 port 这个补丁。
