亲和性作用域
============
一个非绑定工作队列根据其亲和性作用域来对CPU进行分组以提高缓存
局部性。比如如果一个工作队列使用默认的“cache”亲和性作用域，
它将根据最后一级缓存的边界来分组处理器。这个工作队列上的工作项
将被分配给一个与发起CPU共用最后级缓存的处理器上的工作者。根据
``affinity_strict`` 的设置，工作者在启动后可能被允许移出
所在作用域，也可能不被允许。
工作队列目前支持以下亲和性作用域。
``default``
使用模块参数 ``workqueue.default_affinity_scope`` 指定
的作用域，该参数总是会被设为以下作用域中的一个。
``cpu``
CPU不被分组。一个CPU上发起的工作项会被同一CPU上的工作者执行。
这使非绑定工作队列表现得像是不含并发管理的每CPU工作队列。
``smt``
CPU被按SMT边界分组。这通常意味着每个物理CPU核上的各逻辑CPU会
被分进同一组。
``cache``
CPU被按缓存边界分组。采用哪个缓存边界由架构代码决定。很多情况
下会使用L3。这是默认的亲和性作用域。
``numa``
CPU被按NUMA边界分组。
``system``
所有CPU被放在同一组。工作队列不尝试在临近发起CPU的CPU上运行
工作项。
默认的亲和性作用域可以被模块参数 ``workqueue.default_affinity_scope``
修改，特定工作队列的亲和性作用域可以通过 ``apply_workqueue_attrs()``
被更改。
如果设置了 ``WQ_SYSFS`` ，工作队列会在它的 ``/sys/devices/virtual/workqueue/WQ_NAME/``
目录中有以下亲和性作用域相关的接口文件。
``affinity_scope``
读操作以查看当前的亲和性作用域。写操作用于更改设置。
当前作用域是默认值时，当前生效的作用域也可以被从这个文件中
读到（小括号内），例如 ``default (cache)`` 。
``affinity_strict``
默认值0表明亲和性作用域不是严格的。当一个工作项开始执行时，
工作队列尽量尝试使工作者处于亲和性作用域内，称为遣返。启动后，
调度器可以自由地将工作者调度到系统中任意它认为合适的地方去。
这使得在保留使用其他CPU（如果必需且有可用）能力的同时，
还能从作用域局部性上获益。
如果设置为1，作用域内的所有工作者将被保证总是处于作用域内。
这在跨亲和性作用域会导致如功耗、负载隔离等方面的潜在影响时
会有用。严格的NUMA作用域也可用于和旧版内核中工作队列的行为
保持一致。
亲和性作用域与性能
==================
如果非绑定工作队列的行为对绝大多数使用场景来说都是最优的，
不需要更多调节，就完美了。很不幸，在当前内核中，重度使用
工作队列时，需要在局部性和利用率间显式地作一个明显的权衡。
更高的局部性带来更高效率，也就是相同数量的CPU周期内可以做
更多工作。然而，如果发起者没能将工作项充分地分散在亲和性
作用域间，更高的局部性也可能带来更低的整体系统利用率。以下
dm-crypt 的性能测试清楚地阐明了这一取舍。
测试运行在一个12核24线程、4个L3缓存的处理器（AMD Ryzen
9 3900x）上。为保持一致性，关闭CPU超频。 ``/dev/dm-0``
是NVME SSD（三星 990 PRO）上创建，用 ``cryptsetup``
以默认配置打开的一个 dm-crypt 设备。
场景 1: 机器上遍布着有充足的发起者和工作量
------------------------------------------
使用命令：::
$ fio --filename=/dev/dm-0 --direct=1 --rw=randrw --bs=32k --ioengine=libaio \
--iodepth=64 --runtime=60 --numjobs=24 --time_based --group_reporting \
--name=iops-test-job --verify=sha512
这里有24个发起者，每个同时发起64个IO。 ``--verify=sha512``
使得 ``fio`` 每次生成和读回内容受发起者和 ``kcryptd``
间的执行局部性影响。下面是基于不同 ``kcryptd`` 的亲和性
作用域设置，各经过五次测试得到的读取带宽和CPU利用率数据。

* - cache (strict)
- 1166.00 ±0.71
- 99.35 ±0.01
在系统中分布着足够多发起者的情况下，不论严格与否，“cache”
没有表现得更差。三种配置均使整个机器达到饱和，但由于提高了
局部性，缓存相关的两种有0.6%的（带宽）提升。
场景 2: 更少发起者，足以达到饱和的工作量
----------------------------------------
使用命令：::
$ fio --filename=/dev/dm-0 --direct=1 --rw=randrw --bs=32k \
--ioengine=libaio --iodepth=64 --runtime=60 --numjobs=8 \
--time_based --group_reporting --name=iops-test-job --verify=sha512
与上一个场景唯一的区别是 ``--numjobs=8``。 发起者数量
减少为三分之一，但仍然有足以使系统达到饱和的工作总量。

- 96.15 ±0.09
* - cache (strict)
- 1112.00 ±4.64
- 93.26 ±0.35
这里有超过使系统达到饱和所需的工作量。“system”和“cache”
都接近但并未使机器完全饱和。“cache”消耗更少的CPU但更高的
效率使其得到和“system”相同的带宽。
八个发起者盘桓在四个L3缓存作用域间仍然允许“cache (strict)”
几乎使机器饱和，但缺少对工作的保持（不移到空闲处理器上）
开始带来3.7%的带宽损失。
场景 3: 更少发起者，不充足的工作量
----------------------------------
使用命令：::
$ fio --filename=/dev/dm-0 --direct=1 --rw=randrw --bs=32k \
--ioengine=libaio --iodepth=64 --runtime=60 --numjobs=4 \
--time_based --group_reporting --name=iops-test-job --verify=sha512
再次，唯一的区别是 ``--numjobs=4``。由于发起者减少到四个，
现在没有足以使系统饱和的工作量，带宽变得依赖于完成时延。
.. list-table::

- 74.90 ±0.07
* - cache (strict)
- 828.20 ±4.49
- 66.84 ±0.29
现在，局部性和利用率间的权衡更清晰了。“cache”展示出相比
“system”2%的带宽损失，而“cache (strict)”跌到20%。
结论和建议
----------
在以上试验中，虽然一致并且也明显，但“cache”亲和性作用域
相比“system”的性能优势并不大。然而，这影响是依赖于作用域
间距离的，在更复杂的处理器拓扑下可能有更明显的影响。
虽然这些情形下缺少工作保持是有坏处的，但比“cache (strict)”
好多了，而且最大化工作队列利用率的需求也并不常见。因此，
“cache”是非绑定池的默认亲和性作用域。
* 由于不存在一个适用于大多数场景的选择，对于可能需要消耗
大量CPU的工作队列，建议通过 ``apply_workqueue_attrs()``
进行（专门）配置，并考虑是否启用 ``WQ_SYSFS``。
* 设置了严格“cpu”亲和性作用域的非绑定工作队列，它的行为与
``WQ_CPU_INTENSIVE`` 每CPU工作队列一样。后者没有真正
优势，而前者提供了大幅度的灵活性。
* 亲和性作用域是从Linux v6.5起引入的。为了模拟旧版行为，
可以使用严格的“numa”亲和性作用域。
* 不严格的亲和性作用域中，缺少工作保持大概缘于调度器。内核
为什么没能维护好大多数场景下的工作保持，把事情作对，还没有
理论上的解释。因此，未来调度器的改进可能会使我们不再需要
这些调节项。

* -Practically rewrote the I/D TLB Miss handlers
* Now 40 and 135 instructions a peice as compared to 131 and 449 resp.
* Now 40 and 135 instructions apiece as compared to 131 and 449 resp.
* Hence Leaner by 1.5 K
* Used Conditional arithmetic to replace excessive branching
* Also used short instructions wherever possible

Say Y here to enable options which enable mitigations for hardware

Mitigations can be disabled or restricted to SMT systems at runtime
via the "mitigations" kernel parameter.
If you say N, all mitigations will be disabled. You really
should know what you are doing to say so.
