THIS IS DEPRECATED!
Writing to memory.soft_limit_in_bytes has no effect and reading it will
always return the maximum value.
Soft limits allow for greater sharing of memory. The idea behind soft limits
is to allow control groups to use as much of the memory as needed, provided
Use memory.low and memory.min in cgroup v2 instead.
a. There is no memory contention
b. They do not exceed their hard limit
When the system detects memory contention or low memory, control groups
are pushed back to their soft limits. If the soft limit of each control
group is very high, they are pushed back as much as possible to make
sure that one control group does not starve the others of memory.
Please note that soft limits is a best-effort feature; it comes with
no guarantees, but it does its best to make sure that when memory is
heavily contended for, memory is allocated based on the soft limit
hints/setup. Currently soft limit based reclaim is set up such that
it gets invoked from balance_pgdat (kswapd).
7.1 Interface
-------------
Soft limits can be setup by using the following commands (in this example we
assume a soft limit of 256 MiB)::
# echo 256M > memory.soft_limit_in_bytes
If we want to change this to 1G, we can at any time use::
# echo 1G > memory.soft_limit_in_bytes
.. note::
Soft limits take effect over a long period of time, since they involve
reclaiming memory for balancing between memory cgroups
.. note::
It is recommended to set the soft limit always below the hard limit,
otherwise the hard limit will take precedence.

can be used to ensure that calls to those functions are serialized. Those
functions also support guard() and scoped_guard() variants.
Drivers can call hwmon_notify_event() to notify userspace and the thermal
subsystem when a hardware monitoring event (such as an alarm or a fault
condition) occurs or clears. The parameters are the hwmon device, the sensor
type, the attribute identifier associated with the event (such as
hwmon_temp_max_alarm or hwmon_fan_fault), and the sensor channel number.
hwmon_notify_event() generates a sysfs event (calling sysfs_notify()) and a
udev event with the attribute name passed in the NAME environment property
(e.g., "NAME=temp1_max_alarm"). If the event is for a temperature sensor and
the sensor is attached to a thermal zone, it also notifies the thermal
subsystem to update the thermal zone. hwmon_notify_event() returns 0 on
success or a negative error code on failure.

Scheduler-Dependent Knobs
-------------------------
The fair-class scheduler enforces CPU controller settings such as
``cpu.max``, ``cpu.weight`` and ``cpu.idle``. For sched_ext tasks, the
scheduler core communicates these settings to the BPF scheduler
through ``ops.cgroup_init()`` and reports subsequent changes through
the corresponding ``ops.cgroup_set_*()`` callbacks. Similarly, per-task
nice changes are converted to weights and reported through
``ops.set_weight()``.
Each BPF scheduler is responsible for implementing the scheduling
semantics of these settings and may choose to ignore them. Consult the
loaded scheduler's documentation before relying on these controls.

概述
----
RISC-V 指令集体系结构是公开开发的:
RISC-V指令集体系结构是公开开发的
正在进行的草案可供所有人查看和测试实现。新模块或者扩展草案可能会在开发过程中发
生更改 --- 有时以不兼容的方式对以前的草案进行更改。这种灵活性可能会给 RISC-V
Linux 维护者带来挑战。Linux 维护者不赞成频繁的变更,且 Linux 开发过程更喜欢经过
良好检查和测试的代码,而不是试验代码。我们希望推广同样的规则到即将被内核合并的
RISC-V 相关代码。
Patchwork
---------
RISC-V 有一个 patchwork 实例,可以在那里查看补丁的状态:
https://patchwork.kernel.org/project/linux-riscv/list/
如果你的补丁不在默认视图中出现,那么 RISC-V 维护者很有可能已要求修改,或者希望
将其应用到另一个代码树上。
自动化流程会在该 patchwork 实例上运行,在每个补丁到达时立刻对其进行构建/测试。
自动化流程会根据补丁是否被识别为修复,选用 RISC-V `for-next``fixes` 分支
当前的 HEAD若上述均应用失败则使用 RISC-V `master` 分支。补丁系列被应用到的具
体提交将标注在 patchwork 上。任何检查未通过的补丁通常不会被应用,并且在大多数情
况下将需要重新提交。

附加的提交检查单
----------------
我们仅接受针对新模块或扩展的补丁,前提是这些模块或扩展的规范被列为未来不太可能发
生不兼容的变更。对于来自 RISC-V 基金会的规范,这意味着“已冻结”或“已批准”,对于
UEFI 论坛的规范,这意味着已发布的 ECR。开发者当然可以维护自己的 Linux 内核树,
其中包含他们所需的任何扩展草案的代码。)
我们仅接受相关标准已经被RISC-V基金会标准为“已批准”或“已冻结”的扩展或模块的补丁。
开发者当然可以维护自己的Linux内核树其中包含所需代码扩展草案的代码。
此外RISC-V 规范允许实现者创建自己的自定义扩展。这些自定义扩展不需要通过 RISC-V
基金会的任何审核或批准流程。为了避免因添加实现者特定的 RISC-V 扩展带来的维护复杂
性和对性能的潜在影响,我们将只考虑符合以下任一条件的扩展补丁:
- 已由 RISC-V 基金会正式冻结或批准
- 已按照标准 Linux 惯例,在广泛可用的硬件中实现
(实现者当然可以维护自己的 Linux 内核树,其中包含他们所需的任何自定义扩展的代码。)
此外RISC-V规范允许爱好者创建自己的自定义扩展。这些自定义拓展不需要通过RISC-V
基金会的任何审核或批准。为了避免将爱好者一些特别的RISC-V拓展添加进内核代码带来

补丁。开发者当然可以维护自己的Linux内核树其中包含他们想要的任何自定义扩展

映射的优点是固定时间查找IRQ号而且irq_descs只分配给在用的IRQ。 缺点是该表

irq_domain_add_linear()和irq_domain_create_linear()在功能上是等价的,
