相关申请的交叉引用
本申请要求2014年12月22日提交的“DelayedTrimofManagedNANDFlashMemoryinComputingDevices”的美国专利申请号62/095,470的优先权。前述专利申请由此通过引用整体并入本文。
技术领域
本发明一般涉及电子器件中的闪速存储器，并且更具体地涉及所管理的NAND闪速存储器。
背景技术
为了使所管理的NAND闪速存储器正常工作并且提供领域中的长寿命，闪存控制器必须清楚哪些闪存单元处在“使用中”。该“使用中”信息用于允许损耗均衡和其他闪存维护。可用于保持通知控制器未使用的组块的传统方法是在每个组块上实施TRIM命令，即“修整”闪速存储器。典型地，TRIM指令允许操作系统告知闪存控制器哪些组块数据不再被使用，并且能够被擦除和再被使用。然而，删除之后立即实施TRIM命令能够对文件系统性具有显著的影响。尽管由于在文件系统中的内部计算在未来机会时大多数文件系统能够再使用那些组块，但是一旦删除文件，大多数文件系统不提供确定哪些组块空闲的低影响方法。然而，由于闪存控制器不清楚这些“未使用”组块，因此其不能够使用它们以用于闪存维护。
发明内容
在本发明的一个方面中，一种管理电子器件中NAND闪速存储器的方法，包括：收集针对删除或截取(truncation)而标记的文件；监控电子器件的活跃水平；监控针对删除或截取而标记的文件列表的总大小；确定电子器件是否空闲；以及如果满足预定标准，则修整电子器件的闪速存储器；由此最小影响电子器件的系统性能。
在实施例中，该方法包括在电子器件的开机启动时间(boottime)加载文件系统过滤器驱动器。
在另一实施例中，该方法包括设置文件系统驱动器的正确过滤器模式。
在另一实施例中，该方法包括为文件系统过滤器驱动器指定线程优先级(threadpriority)。
在又一实施例中，该方法包括从文件系统器件驱动器创建到电子器件的文件系统的挂钩(hook)。
在另一实施例中，该方法包括将文件系统I/O功能扩展至文件系统器件驱动器。
在另一实施例中，该方法包括产生(spawning)进程以监控电子器件空闲时间。
在实施例中，该方法包括创建系统文件夹以包含针对删除或截取而标记的文件。
在另一实施例中，该方法包括产生进程以监控系统文件夹。
在另一实施例中，该方法包括将针对删除或截取而标记的文件移动至系统文件夹。
在实施例中，在系统文件夹超出预定大小之后，发生修整电子器件的闪速存储器。
在实施例中，在下一次重新开机启动(reboot)电子器件时修整电子器件的闪速存储器。
在实施例中，当确定电子器件空闲时发生修整电子器件的闪速存储器。
在本发明的另一方面，一种管理电子器件中的NAND闪速存储器的方法，包括：提供具有带有文件系统的NAND闪速存储器的电子器件，和具有文件系统I/O功能的操作系统；提供电子器件上的文件系统过滤器驱动器，该文件系统过滤器驱动器操作成：执行操作系统的文件系统I/O功能，监控电子器件的活跃水平，创建系统文件夹以包含针对删除或截取而标记的文件，将针对删除或截取而标记的文件移动至系统文件夹，确定电子器件是否空闲，监控系统文件夹的大小，以及如果满足预定标准则修整电子器件的闪速存储器；由此闪速存储器的TRIM操作最小影响电子器件的系统性能。
在一个实施例中，该方法包括将电子器件配置成在电子器件的开机启动时间加载文件系统过滤器驱动器。
在一个实施例中，文件系统过滤器驱动器操作成产生监控电子器件空闲时间的进程。
在另一个实施例中，文件系统过滤器驱动器操作成产生监控系统文件夹的进程。
在再一个实施例中，文件系统过滤器驱动器操作成在系统文件夹超出预定大小之后修整电子器件的闪速存储器。

在又一实施例中，文件系统过滤器驱动器操作成在确定电子器件空闲时修整电子器件的闪速存储器。
附图说明
现在将参考附图借助于实例描述本发明，附图中：
图1是具有操作成管理NAND闪速存储器的软件的电子器件的框图；
图2是在电子器件上管理NAND闪速存储器的方法的流程图；和
图3是在操作成管理NAND闪速存储器的电子器件上安装和设置软件的方法的流程图。
具体实施方式
一般地，一种在电子器件中管理NAND闪速存储器的方法最小化闪速存储器的TRIM操作的系统性能影响。如下文将进一步具体描述的，该方法包括：提供具有NAND闪速存储器的电子器件，该NAND闪速存储器具有文件系统、具有文件系统I/O功能的操作系统；并且在电子器件上提供文件系统过滤器驱动器。文件系统过滤器驱动器操作成执行操作系统的文件系统I/O功能；监控电子器件的活跃水平；创建系统文件夹以包含针对删除或截取而标记的文件；将针对删除或截取而标记的文件移动至系统文件夹；确定电子器件是否空闲；以及在最佳时段(诸如空闲时间)期间修整电子器件的闪速存储器，如果系统文件夹已经超出预定大小则重新开机启动。
参考图1，示范性电子器件100包括处理器102、闪速存储器控制器104、NAND闪速存储器106、以及至少一个主文件系统107。如下文将进一步描述的系统文件夹108操作成临时积累针对删除或截取而标记的文件。文件系统107被存储在闪速存储器106中。系统文件夹108进而被存储在文件系统107中。电子器件100还包括存储器110。电子器件100包括操作系统112和文件系统过滤器驱动器114，用于管理来自文件系统107的删除。文件系统过滤器驱动器114包括IdleThread线程116和TrimThread线程118，在下文中将对其更具体地描述，其分别监控电子器件100的活跃和系统文件夹108的大小。
参考图2，在200处，文件系统过滤器驱动器114被实施为始终监视哪些文件针对删除或截取而已经被标记。文件系统过滤器驱动器114收集这些标记的文件。文件系统过滤器驱动器114还监控器件的活跃水平204和针对删除或截取而标记的文件的总大小206。文件系统过滤器驱动器114还确定电子器件100何时空闲208并且在最佳时间处“修整”闪速存储器210。通过保持这些文件集合在一边，在稍后的时间可执行TRIM指令以删除和/或截取该文件。根据本公开，在用户请求删除时，不是立即删除文件(和关于属于该文件的区块去除知识(knowledge))，代替地重命名或移动该文件。这允许现在未使用的区块的记录被保持和保护。随后，在适当时间，利用TRIM指令删除标记的文件。适当时间可以是在存在一定量的‘要修整的文件’之后的下一个重新开机启动，或者是当已知系统不太忙的时候，所以用户将不会注意到性能影响。
参考附图3，在300处，一般地示出设置电子器件以实施管理NAND闪速存储器的方法的方法。302在开机启动时间加载文件系统过滤器驱动器114。在开机启动时，文件系统过滤器驱动器114读取针对期望要被设置的正确“过滤器模式”的登记(registry)304。也针对期望要被分派文件系统过滤器驱动器线程(即进程)的正确线程优先级读取登记(在Windows系统中)306。文件系统过滤器驱动器114对文件系统上的特定空间也将设置挂钩308。这允许文件系统管理器知道何时调用文件系统过滤器驱动器114。文件系统I/O功能诸如删除文件、创建文件夹、移除文件夹等也扩展至文件系统过滤器驱动器114以使这些功能能够被直接调用310。在Windows系统中，要被输出的功能能够在文件系统驱动器过滤器114的.def文件中找到。
一旦完成该设置，文件系统驱动器过滤器114创建一个或多个系统文件夹，其中文件能够被移动以用于稍后修整312。这些系统文件夹的名称可以是“$Trim.bin”或其他合适的文件名。位置可以在文件系统的根部或者其他合适位置。该文件夹也被指定为系统文件夹并且被隐藏以防止内容的无意篡改。文件系统驱动器过滤器114产生两个线程314、316。具体地，空闲线程(IdleThread)和修整线程(TrimThread)。空闲线程的目的是测量系统空闲时间。修整线程的目的是针对要被修整的任何文件持续监控$Trim.bin文件夹。一旦找到并且检测到正确的系统条件，则文件系统过滤器驱动器114现在能够执行TRIM指令以基于之前设置的过滤器模式修整文件。
修整线程(TrimThread)线程持续监控系统中的条件。如之前提及的，特定条件能够允许修整线程不修整文件。这些条件可以是：系统处于繁忙状态并且被暂停。修整线程也能够调整自身到其中文件被更积极修整的特定系统条件。这些条件可以包括处于“齐平(flush)”模式并且接近达到修整文件夹的最大大小。
当用户在文件系统过滤器驱动器114已经创建挂钩到其中的卷上调用面对客户删除文件API时，文件仅被移动到$Trim.bin文件夹。已经被输出的大部分其他功能简单地接替用户指令下至可以或者可以不被设置在电子器件上的其他过滤器。
总之，本领域技术人员从上文描述和图示将意识管理NAND闪速存储器的公开方法增强了电子器件的总体性能。通过在电子器件空闲时保存文件的删除和截取一段时间，对用户最小化TRIM指令对电子器件的系统性能的影响，因而增强了用户的生产率。
虽然本文中示出并且描述体现公开内容的某些特定结构，但是对本领域技术人员很显然的是，可以对部件进行各种修改和重新设置而不脱离以下原理的精神和范围并且其不限于本文示出和描述的特定形式，除了如由所附权利要求的范围指示的范围之外。
