【考研英语】你知道词根priv是什么意思吗？ - 知乎

【考研英语】你知道词根priv是什么意思吗？ - 知乎切换模式写文章登录/注册【考研英语】你知道词根priv是什么意思吗？考研盒子干货满满，精彩纷呈，为你打开高校百宝箱~Hello，大家好呀！又和大家见面了。本系列给大家推送的是结合词根词缀来串讲单词。英语词根词缀的学习是一项长期系统的工程，我们在串讲单词时也会涉及到前面讲过的词根词缀，所以这要求同学们在每一次的学习之前多多复习前面讲过的单词，只有这样才能更好地开始接下来的学习。今天要给同学们讲的是一个看起来比较陌生的词根——priv，那么这个词根是什么意思呢？来看下面的单词吧：1.private常考词义：adj.私人的，私有的；私立的；私营的不常考词义：adj.不公开的，秘密的；内向的n. 列兵；二等兵派生词：privacy n. 隐私；私密；不受公众干扰的状态privately adv. 私下地；秘密地privatization n. 私有化privateer n. 私掠船；武装民船；私掠船船长；私掠船船员vi. 私掠巡航privatize vt. 使私有化；使归私有常考搭配：inprivate 私下地；秘密地这个单词同学们应该很熟悉了，但很少有人知道它的构成。它由词根priv与后缀ate构成。我们以前很少给同学们讲解过后缀，而这次这个后缀比较特殊，我们来好好讲解一下，同学们做好笔记哦。通常情况下这个后缀有三个属性，第一个属性是表示动词，很多动词结尾都是ate，表示使、做；第二个属性是表示形容词，例如considerate含义是考虑周到的。第三个属性是表示名词，通常表示人或者职位，例如candidate含义是候选人。这里的private就采用了后两种属性，词根priv表示个人、单个，在后缀ate表示形容词时，这个单词的含义就是个人的，而个人的就是仅自己拥有的，所以就有了私人的和不公开的含义。而当后缀ate表示名词时，这个单词的含义就是表示单个的人，通常指军队中的单兵，也就是列兵。2.deprive常考词义：vt.使丧失，剥夺派生词：deprivation n. 剥夺；损失；免职常考搭配：deprivesb of sth 剥夺某人某物这个单词由前缀de与词根priv构成，最后的字母e补充音节，没有实际含义。首先来看前缀de，这个前缀之前给大家专门写文章讲过，可以再去回顾一下，这里的含义是去掉、取消。结合词根priv表示个人的意思，那这个单词的字面含义即为：去掉个人，补充一下就是去掉个人的其他东西或者从个人身上去掉，也就是使个人丧失或者剥夺的意思。3.privilege常考词义：n.特权；优待不常考词义：vt.给予…特权；特免派生词：privileged adj. 享有特权的；有特别恩典的v. 给予…特权；免除（过去分词）常考搭配：specialprivilege 特权；特别优惠；特殊许可这个单词的构成比较特殊，由两个词根构成，其中一个词根是priv，而另外一个词根不知道同学们发现没有呢，就是leg，这个词根表示法律。结合在一起，这个单词的字面意思就是个人的法律。我们都知道，法律是面向所有人的，所谓个人的法律就是超越了一般的法律，不必遵守一般的法律，那这就是特权，所以这个单词的主要意思就是特权，另外，它还可以作动词表示给予……特权，不知道同学们理解了没有呢？总之，今天给同学们讲解了由词根priv构成的一系列单词，同学们要结合我们的讲解内容把这些单词都记住哦，这些都是考研重点单词，相信通过我们的讲解同学们一定能记得更牢，同学们加油！长按添加研盒小助手微信免费咨询择校指南/复习规划/学习方法关注考研指鹿，考研学习不迷路！（微博账号也期待大家的关注呀！）新浪微博：@考研指鹿（更多微博福利等你来拿~）发布于 2021-08-08 18:01英语词根词根词缀词根赞同添加评论分享喜欢收藏申请

滑盖全键盘的 Android：黑莓 Priv 上手 - 知乎

滑盖全键盘的 Android：黑莓 Priv 上手 - 知乎切换模式写文章登录/注册滑盖全键盘的 Android：黑莓 Priv 上手爱搞机有趣到扑×的科技数码视频号！最近在 Code/Mobile 大会上闹得沸沸扬扬的黑莓，CEO 程守宗表示如果一年内手机业务没有盈利，将可能选择放弃。不过想要在现在 Android 和 iOS 两分天下的情况下实现盈利可没那么简单，所以黑莓也是一改往日的作风，首次推出搭载了 Android 系统的 Priv，标志性的实体全键盘没有缺席。WebStandard 网站记者有幸的体验到这台未上市的 Priv，当然是 Not for Sale的工程机了，Derstand 将其体验完整的记录了下来，爱搞机对其进行翻译整理后给大家参考。首先需要事先声明，这次体验基于工程机，所以在参数配置等方面可能会与最后发售的机器存在出入，敬请留意。实际上手体验中硬件部分已经接近完成，可能会有一些小地方会进行修改，至于软件部分还未定型，与发售机器或许差异较大，预计会在 2016 年初发售。编者注：在黑莓官网上已经注明 coming this Fall，CEO 程守宗也在大会上说年底前发售，考虑到 Derstand 网站在欧洲，2016 年初或许是在欧洲上市的时间。硬件参数Priv 拥有一块 5.4 英寸的曲面屏幕，不过这块曲面屏幕和三星 Galaxy S6 Edge 的不尽相同。分辨率为 2560x1440（2K），高达 544 的 PPI 对于 VR 可能会有用处，不过日常使用中肉眼并没有感觉到和 1080P 的区别。Priv 使用和 LG G4 一样的高通 Snapdragon 808 处理器，3GB 的 RAM，32GB 的 ROM，其中用户可用 22 GB。同样支持 LTE，蓝牙 4.1，NFC 这些无线连接，配备 1800 万像素的施耐德镜头和 500 万前置摄像头，双色温闪光灯。遗憾的是仍然使用 USB2.0 的 microUSB，没有使用更新的 USB 3.0 或者 USB Type-C。编者注：近日又传出消息，黑莓 Priv 可能用上索尼的 IMX230 CMOS，最后发售的版本也许是 2100 万像素的主摄像头，具体情况只能等实际上市后才能知道。为双手使用设计Priv 的 5.4 寸屏幕设计本来就不适宜单手操作了，还有实体全键盘的加入和那个小小的扬声器下巴，尽管使用虚拟导航键节省了一点空间，不过 Priv 的操作大部分还是得用双手完成。机器的后背采用多种材质混合组成，其中含有凯夫拉。摸上去的话有点“廉价感”，好处则是摩擦力不错，拿在手中不容易滑落。位于屏幕下方就是黑莓一直坚持的全键盘，看上去坚固耐用，不过按键之间存在缝隙，容易积灰需要经常清理。屏幕显示效果不亚于广受好评的 LG G4，色彩鲜艳，对比度高。黑莓正尝试像三星那样为侧边的曲面屏幕加入一些小功能，例如充电时的动画，这台工程机上碍于软件的原因没有实现。机身左侧是电源键，位置偏高不容易碰到。右侧则是和黑莓以往的机型一样配备了音量调节键和“静音”键，不过中间的“静音”键不是实现静音功能，按下后会弹出通知，即使是在运行相机的时候也能使用。不知道黑莓未来会不会为这颗按键添加更多的功能。性能够用，不突出使用 32 位的安兔兔进行跑分，分数是 46000，仅仅排在了 2014 年发售的 HTC M8 和一加前面，不算出色。大部分情况下运行流畅，小部分时候会出现卡顿，考虑到这是工程机也属正常现象，而且黑莓在正式发售前也能再进行优化。系统 UI 几乎和原生一致，但是黑莓在底部的导航键上旁边加了一个键盘按钮，点击可以弹出虚拟键盘，对于有实体键盘的 Priv 来说，有点多此一举，正式发售的时候预计应该会取消这个按钮。（对于黑莓能用上 808 已经很好了，当年别的厂商都开始用双核处理器的时候，这货还在用 624MHz 的单核呢）依旧出色的键盘根据上手记者的评价，这款键盘手感依旧出色，键粒分明，键程设计合理。只是现在大多数人习惯了虚拟键盘，实体键盘键粒稍小和需要一点力度敲击，适应一段时间后输入效率应该会更好。体验的工程机键盘是经典的 QWERTY 布局，针对的是使用英语的国家，按照黑莓以往的惯例，在不同地区应该会发售键盘布局不同的型号。关于应用设置的时候可以从 iPhone，Android 或者 BlackBerry OS（5.0 以上）导入用户数据到 Priv 上，黑莓也预装了自家的应用，例如 BlackBerry Messenger 的 IM 应用，还有叫做 safe guard 的安全应用，为当前的安全设置打个分。同样，作为一台 Android 机器，Google 家的应用也有预装，包括 Gmail，Chrome 和 Play Store 等等。作为黑莓之前最大的软肋——第三方应用，由于 Android 的加入，已经不再是问题，如何在 Android 系统中维持和原来一样的安全性和保密性才是这回 Priv 的重点。相机，通话和续航相机不错，却没有让人眼前一亮。白天对焦速度快，细节清晰，色彩还原真实；夜间开启闪光灯的话，快门对焦速度明显降低，虽然配备了 OIS，还是对成像有一定的影响，黑莓还得再对相机方面进行优化和调教。拍照方面口说无凭，还是丢出样张给大家自行判断，最后一张是利用前置摄像头的自拍。通话和听音乐，无论是在移动网络还是 Wi-Fi 下，都表现出色，维持一贯的传统。续航方面，由于上手时间的缘故，没有更详尽的测试。在 2 个半小时的重度使用下，电量从 100% 降到 85%，预计 Priv 正常使用应该能坚持 1 天到 1 天半。尾巴这次 Derstand 的上手体验文由于时间关系，并没有很深入的体验，大部分情况和当前别的 Android 机器没有很大的区别，除了那个标志性的实体全键盘以外。既然黑莓 Priv 的命名来源于单词 Privacy，那么重点就是在其系统上有什么特别之处，不过这篇体验文对于系统部分介绍不多，不确定是不是由于保密协议不能透露，还是工程机没有完善，究竟如何看来还得等真机发售之后才能知道。黑莓如果想要靠 Priv 翻身，仅仅为 Android 加上个键盘是不够的，即使有再多的情怀也没办法挑战市场。图文来源自 Derstand发布于 2019-01-01 10:42科技Blackberry（黑莓）Android赞同添加评论分享喜欢收藏申请

关于目录

/system/priv-app 中包括 Launcher，SystemUI，SettingsProvider 等，均是系统的核心应用，这些应用能使用系统级的权限，4.4 之前的所有 /system/app 下的软件都能使用系统级的权限，Google 这样做是把内置到系统的应用也做个级别的区别。

放到 /system/priv-app 下的应用比放到 /system/app 下的应用可以声明获得更多的权限。在Android中每个应用都有自己的权限声明，比如要使用系统限制的权限（例如 android.permission.WRITE_SECURE_SETTINGS），我们就需要把程序安装到 /system/app 下。

手机被 root 后，通过 adb push 可以把 apk 推送到这两个目录，作为系统应用，用户无法删除。

关于进程

从应用的运行角度来说，/system/priv-app 中的 service 是不能被 kill 掉的，就算通过 adb kill 掉后系统也会重新拉起。例如：

Line 14879: 09-28 10:07:06.352 1624 2165 W ActivityManager: Scheduling restart of crashed service com.xxx.xxx/.xxx.xxxin 1000ms

Line 14907: 09-28 10:07:06.366 1624 2165 I ActivityManager: Start proc 5588:com.xxx.xxx/u0a96 for restart com.xxx.xxx

好处是进程可以保持始终运行，并且能拿到最多的权限；坏处是无法正常升级，因为一被 kill 马上又被拉起来，并且升级完成后，再起来的还是旧版本的 service。

所以，我们的应用被预装到终端手机 ROM 中时，为了保活，并且尽量减少终端厂商的工作量，如果能解决升级的问题，对于终端厂商来说就只需要把应用 push 到 /system/priv-app 下就可以了。没有找到解决升级的办法，最终采用的方案往往是 push 到 /system/app，系统通过一个 service（如 phone）来 bind 我们的 service，一旦 disconnect 之后再来 bind，实现保活。

关于 System App

在 PackageManagerService 中对是否是 System App 的判断：

private static boolean isSystemApp(PackageParser.Package pkg) {

return (pkg.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0;

}

private static boolean isSystemApp(PackageSetting ps) {

return (ps.pkgFlags & ApplicationInfo.FLAG_SYSTEM) != 0;

}

具有 ApplicationInfo.FLAG_SYSTEM 标记的，被视为 System App。

有两类 App 属于 System App ：

1 . 特定 shared uid 的 App

例如： shared uid 为

android.uid.system，

android.uid.phone，

android.uid.log，

android.uid.nfc，

android.uid.bluetooth，

android.uid.shell。这类 App 都被赋予了

ApplicationInfo.FLAG_SYSTEM 标志。

2 . 特定目录中的 App

特定目录包括：

/vendor/overlay，

/system/framework，

/system/priv-app，

/system/app，

/vendor/app，

/oem/app。这些目录中的 App，被视为 System App。

关于 Privileged App

Privileged App，即「特权应用」，主要原因是此类特权 App 可以使用 protectionLevel 为 signatureOrSystem 或者 protectionLevel 为 signature|privileged 的权限。

从 PackageManagerService 的 isPrivilegedApp() 可以看出特权 App 是具有 ApplicationInfo.PRIVATE_FLAG_PRIVILEGED 标志的一类 App。

private static boolean isPrivilegedApp(PackageParser.Package pkg) {

return (pkg.applicationInfo.privateFlags & ApplicationInfo.PRIVATE_FLAG_PRIVILEGED) != 0;

}

特权 App 首先必须是 System App，也就是说 System App 分为普通的 System App 和特权的 System App（System App = 普通 System App + 特权 App）。

直观的（但不准确严谨）说，普通的 System App 就是 /system/app 目录中的 App，特权的 System App 就是 /system/priv-app 目录中的 App（priv-app 是 privileged app 的简写）。

两类 Privileged App

特权 App 首先是 System App，然后要具有 ApplicationInfo.PRIVATE_FLAG_PRIVILEGED 标志。

有两类 App 属于 Privileged App（特权 App）：

参考 PackageManagerService 的构造方法

特定 uid 的 App

shared uid 为

android.uid.system，

android.uid.phone，

android.uid.log，

android.uid.nfc，

android.uid.bluetooth，

android.uid.shell 的 App 被赋予了 privileged 的权限。这些 App 同时也是 System App。

特定目录中的 App

/system/framework 和

/system/priv-app 目录下的 App 被赋予了 privileged 的权限。其中

/system/framework 目录中的 apk，只是包含资源，不包含代码（dex）。

Brief summary :

- Support more host OS to run on:

- Include win64 native binary in the release.

- Fixed failures on big endian hosts.

- BIOS: Support for up to 2M ROM BIOS images.

- GUI: select mouse capture toggle method in .bochsrc.

- Ported most of Qemu's 'virtual VFAT' block driver

(except runtime write support, but plus FAT32 suppport)

- Added write protect option for floppy drives.

- Bugfixes / improved internal debugger + instrumentation.

Detailed change log :

- CPU and internal debugger

- Implemented Process Context ID (PCID) feature

- Implemented FS/GS BASE access instructions support

(according to document from http://software.intel.com/en-us/avx/)

- Rewritten from scratch SMC detection algorithm

- Bugfixes for CPU emulation correctness and stability

- Fixed failures on Big Endian hosts !

- Print detailed page walk information and attributes in

internal debugger 'page' command

- Updated/Fixed instrumentation callbacks

- Configure and compile

- Bochs now can be compiled as native Windows x86-64 application

(tested with Mingw gcc 4.5.1 and Microsoft Visual Studio Express 2010)

- Added ability to configure CPUID stepping through .bochsrc.

The default stepping value is 3.

- Added ability to disable MONITOR/MWAIT support through .bochsrc

CPUID option. The option is available only if compiled with

--enable-monitor-mwait configure option.

- Determine and select max physical address size automatically at

configure time:

- 32-bit physical address for 386/486 guests

- 36-bit physical address for PSE-36 enabled Pentium guest

- 40-bit physical address for PAE enabled P6 or later guests

- Update config.guess/config.sub scripts to May 2010 revisions.

- Update Visual Studio 2008 project files in build/win32/vs2008ex-workspace.zip

- Added Bochs compilation timestamp after Bochs version string.

- GUI and display libraries (Volker)

- Added new .bochsrc option to select mouse capture toggle method.

In addition to the default Bochs method using the CTRL key and the

middle mouse button there are now the choices:

- CTRL+F10 (like DOSBox)

- CTRL+ALT (like QEMU)

- F12 (replaces win32 'legacyF12' option)

- display library 'x' now uses the desktop size for the maximum guest resolution

- ROM BIOS

- NE2K: Fixed "send buffer" command issue on big endian hosts

- USB

- converted common USB code plus devices to the new 'usb_common' plugin

Now the USB device classes no longer exist twice if both HC plugins are loaded.

- added 'pseudo device' in common USB code for the device creation. This makes

the HCs independent from the device specific code.

- USB MSD: added support for disk image modes (like ATA disks)

- USB printer: output file creation failure now causes a disconnect

- re-implemented "options" parameter for additional options of connected

devices (currently only used to set the speed reported by device and to

specify an alternative redolog file of USB MSD disk image modes)

- hard drive

- new disk image mode 'vvfat'

- ported the read-only part of Qemu's 'virtual VFAT' block driver

- additions: configurable disk geometry, FAT32 support, read MBR and/or

boot sector from file, volatile write support using hdimage redolog_t

class, optional commit support on Bochs exit, save/restore file

attributes, 1.44 MB floppy support, set file modification date/time

- converted the complete hdimage stuff to the new 'hdimage' plugin

- new hdimage method get_capabilities() that can return special flags

- vmware3, vmware4 and vvfat classes now return HDIMAGE_HAS_GEOMETRY flag

- other disk image modes by default return HDIMAGE_AUTO_GEOMETRY if

cylinder value is set to 0

- multiple sector read/write support for some image modes

- new log prefix "IMG" for hdimage messages

- Bochs is now able to install and boot 64-bit Windows images!

(special thanks to Mark Ebersole for his patch)

- Several bugfixes in CPU emulation (mostly for x87 instructions)

- Fixed two critical deadlock bugs in the Win32 gui (patches from @SF tracker)

- Fixes related to the 'show ips' feature

- removed conflicting win32-specific alarm() functions ('win32' and 'sdl' gui)

- feature now works in wx on win32

- Added support for gdb stub on big endian machine (patch by Godmar Back)

- Rewritten obsolete hash_map code in dbg symbols module (patch from @SF)

- BIOS: implemented missing INT 15h/89h (patch by Sebastian Herbszt)

-------------------------------------------------------------------------

Changes in 2.4 (May 3, 2009):

Brief summary :

- Added graphical Bochs debugger frontend for most of the supported platforms.

- Thanks for Chourdakis Michael and Bruce Ewing.

- Many new CPU features in emulation

- Support for > 32 bit physical address space and configurable MSRs

- VMX, 1G pages in long mode, MOVBE instruction

- Bugfixes for CPU emulation correctness, debugger and CPU instrumentation.

- New config interface 'win32config' with start and runtime menu

- USB: added OHCI support, external hub and cdrom

- Added user plugin interface support.

Detailed change log :

- CPU and internal debugger

- Support for VMX hardware emulation in Bochs CPU, to enable configure with

--enable-vmx option

Nearly complete VMX implementation, with few exceptions:

- Dual-monitor treatment of SMIs and SMM not implemented yet

- NMI virtualization, APIC virtualization not implemented yet

- VMENTER to not-active state not supported yet

- No advanced features like Extended Page Tables or VPID

- Support for configurable MSR registers emulation, to enable configure with

--enable-configurable-msrs option

Look for configuration example in .bochsrc and msrs.def

- Support new Intel Atom(R) MOVBE instruction, to enable configure with

--enable-movbe option

- Support for 1G pages in long mode, to enable configure with

--enable-1g-pages option

- Support for > 32 bit physical address space in CPU. Up to 36 bit could be

seen in legacy mode (PAE) and up to 40 bit in x86-64 mode.

Still support the same amount of the physical memory in the memory object,

so system with > 4Gb of RAM yet cannot be emulated.

To enable configure with --enable-long-phy-address option.

- Implemented modern BIOSes mode limiting max reported CPUID function

to 3 using .bochsrc CPU option. The mode is required in order to

correctly install and boot WinNT.

- Added ability to configure CPUID vendor/brand strings through .bochsrc

(patch from @SF by Doug Reed).

- Many bugfixes for CPU emulation correctness (both x86 and x86-64).

- Updated CPU instrumentation callbacks.

- Fixed Bochs internal debugger breakpoints/watchpoints handling.

- Configure and compile

- Added ability to choose Bochs log file name and Bochs debugger log file

name from Bochs command line (using new -log and -dbglog options)

- Removed Peter Tattam's closed source external debugger interface from

the code.

- Removed --enable-guest2host-tlb configure option. The option is always

enabled for any Bochs configuration.

- Removed --enable-icache configure option. The option is always enabled

for any Bochs configuration. Trace cache support still remains optional

and could be configured off.

- Added configure option to compile in GUI frontend for Bochs debugger,

to enable configure with --enable-debugger-gui option.

The GUI debugger frontend is enabled by default with Bochs debugger.

- Removed --enable-port-e9-hack configure option. The feature now could be

configured at runtime through .bochsrc.

- Added configure option to enable/disable A20 pin support. Disabling the

A20 pin support slightly speeds up the emulation.

- reduced dependencies between source files for faster code generation

- BIOS

- Added S3 (suspend to RAM) ACPI state to BIOS (patch by Gleb Natapov)

- Implemented MTRR support in the bios (patches by Avi Kivity and Alex

Williamsion with additions by Sebastian Herbszt)

- Bug fixes

- I/O Devices

- Added user plugin support

- remaining devices converted to plugins: pit, ioapic, iodebug

- added 'plugin_ctrl' bochsrc option to control the presence of optional

device plugins without a separate option. By default all plugins are enabled.

- added register mechanism for removable mouse and keyboard devices

- Hard drive / cdrom

- PACKET-DMA feature now supported by all ATAPI commands

- ATAPI command 0x1A added (based on the Qemu implementation)

- sb16

- Added ALSA sound support on Linux (PCM/MIDI output)

- FM synthesizer now usable with MIDI output (simple piano only)

- Fixed OPL frequency to MIDI note translation

- Fixed MIDI output command

- keyboard

- added keyboard controller commands 0xCA and 0xCB

- USB

- USB code reorganized to support more HC types and devices

- added USB OHCI support written by Ben Lunt

- added external USB hub support (initial code ported from Qemu)

- added USB cdrom support (SCSI layer ported from Qemu)

- added status bar indicators to show data transfer

- VGA

- VBE video memory increased to 16 MB

- implemented changeable VBE LFB base address (PCI only, requires latest

BIOS and VGABIOS images)

- I/O APIC

- implemented I/O APIC device hardware reset

- Config interface

- new config interface 'win32config' with start and runtime menu is now

the default on Windows ('textconfig' is still available)

- win32 device config dialogs are now created dynamicly from a parameter list

(works like the wx ParamDialog)

- changes in textcofig and the wx ParamDialog for compatibility with the new

win32 dialog behaviour

- Bochs param tree index keys are case independent now

- some other additions / bugfixes in the simulator interface code

- Misc

- updated LGPL'd VGABIOS to version 0.6c

- Updated Bochs TESTFORM to version 0.4

- SF patches applied

Changes in 2.3.6 (December 24, 2007):

Brief summary :

+ More than 25% emulation speedup vs Bochs 2.3.5 release!

- Thanks to Darek Mihocka (http://www.emulators.com)

for providing patches and ideas that made the

speedup possible!

+ Up to 40% speedup vs Bochs 2.3.5 release with trace cache optimization!

- Lots of bugfixes in CPU emulation

- Bochs benchmarking support

- Added emulation of Intel SSE4.2 instruction set

Detailed change log :

- CPU

- Added emulation of SSE4.2 instruction set, to enable use

--enable-sse=4 --enable-sse-extension configure options

to enable POPCNT instruction only use configure option

--enable-popcnt

- Implemented MTRR emulation, to enable use --enable-mtrr configure

option. MTRRs is enabled by default when cpu-level >= 6.

- Implemented experimental MONITOR/MWAIT support including optimized

MWAIT CPU state and hardware monitoring of physical address range,

to enable use --enable-monitor-mwait configure option.

- Removed hostasm optimizations, after Bochs rebenchmarking it was found

that the feature bringing no speedup or even sometimes slows down

emulation!

- Merged trace cache optimization patch, the trace cache optimization

is enabled by default when configure with --enable-all-optimizations

option, to disable trace cache optimization configure with

--disable-trace-cache

- Many minor bugfixes in CPU emulation (both ia32 and x86-64)

- Updated CPU instrumentation callbacks

- Bochs Internal Debugger and Disassembler

- Many fixes in Bochs internal debugger and disassembler, some debugger

interfaces significantly changed due transition to the param tree

architecture

- Added support for restoring of the CPU state from external file

directly from Bochs debugger

- Configure and compile

- Renamed configure option --enable-4meg-pages to --enable-large-pages.

The option enables page size extensions (PSE) which refers to 2M pages

as well.

- Removed --enable-save-restore configure option, save/restore feature

changed to be one of the basic Bochs features and compiled by default

for all configurations.

- Added new Bochs benchmark mode. To run Bochs in benchmark mode execute

it with new command line option 'bochs -benchmark time'. The emulation

will be automatically stopped after 'time' millions of emulation

cycles executed.

- Another very useful option for benchmarking of Bochs could be enabled

using new 'print_timestamps' directive from .bochsrc:

print_timestamps: enable=1

- Added --enable-show-ips option to all configuration scripts used to

build release binaries, so all future releases will enjoy IPS display.

- Enable alignment check in the CPU and #AC exception by default for

--cpu-level >= 4 (like in real hardware)

- SF patches applied

Android 4.4起引入了/system/priv-app目录概念，那么它和原来的/system/app目录有什么区别呢？

一句话答案：

只有在/system/priv-app目录下的app或者和这个目录下的app相同签名的app才可以使用android:protectionLevel=signatureOrSystem中的权限

Android官方文档解释 “signatureOrSystem” 级别。

android有4种权限：

normal：低风险权限，只要申请了就可以使用（在AndroidM

Android4.4增加了/system/priv-app/目录，那么它与/system/app/目录有什么差别？本文主要从定义，作用，具体效果等方面进行分析。有一些是网上没有介绍到的内容。如果只是知道 priv-app 目录比 app目录权限大一点，但是不了解具体区别的可以看看。（1）普通应用。只用到了普通权限，比如上网权限等等。（2）system/app 系统应用，用来可以限制无法手动卸载，对系统权限没有要求的情况，无法调用系统api。

Priv日常使用不完全指南（持续更新） - 知乎

Priv日常使用不完全指南（持续更新） - 知乎切换模式写文章登录/注册Priv日常使用不完全指南（持续更新）Niloc甲骨文(中国)软件系统有限公司销售总监写在前面：Priv入手有一段时间了，本身对安卓系统比较熟悉（从G1开始几乎一直保持双手机的使用习惯，黑莓+安卓或苹果），对黑莓更熟悉，所以上手比较快，有一些学来的经验及日常的使用感受，在这里分享出来，希望能帮到其他的Priv用户。 ========================================本文中的部分内容来源于网络，均为公开发布并没有版权要求，本文引用或部分引用，在此表示感谢。由于内容比较杂且本人确实无法一一确认出处，若有侵权请联系本人，会在第一时间删除并公开致歉。以上，再次感谢。========================================1.输入习惯：黑莓爱好者有一大部分是习惯在手机上打五笔的人，不知道是不是像我一样孤陋寡闻：最近才知道诸如某狗某度某讯之类的手机输入法都支持五笔了！这对全键盘手机绝对是大好消息。2.Pushmail及BBM放到一起是因为以前的黑莓系统（BB10以前）需要开通BES/BIS才能使用BBM，即是说Pushmail是BBM的必要条件，所以放到一起。在Priv上设置了邮件帐户之后邮件的到达速度也很快，几乎不影响使用，但和BES/BIS的秒推送还是有区别，设置的邮件帐户可以集成到Hub中。BBM有Android的版本，使用效果除了动态头像外暂时没感觉其他功能与黑莓端不同。3.Hub集成性现阶段Priv上Hub的集成性不太好，只能继承“设置-帐户中的部分消息，而App的推送消息则没有集成。这一点和BB10相比实在不能让人满意：BB10安装的Android端App全部消息都可以在Hub中集成。或许在后续版本更新中会修改，拭目以待吧。4.操控感巨大的屏幕+下推滑盖，本人作为身高185CM的正常男性，感觉单手操控滑开状态的Priv比较难。。。虽然可以实现“上推接听合盖挂机”这样的功能，但单手实在难以通过这样的方式挂机。以前用9810时候的快感荡然无存。在推出状态下，通过手指在物理键盘上移动支持上下/左右滑动屏幕。屏幕右侧曲面部分的便签中，快捷方式无法自定义也是缺憾之一。甚至静音键无法设置其他功能也很蛋疼。不过图片解锁功能非常赞，我在他人旁边解锁10次对方也无法看明白我的解锁方法。5.优化之一：系统的各种禁用本人使用的是美版ATT的Priv（一直用联通4G卡，没想多花钱买港版），到手后首先禁用了全部ATT的App，之后按个人需求禁用了部分Google的App，算是解决了发热&省电问题的第一步。其实我最希望的就是Priv可以Root，让我能完全删除这些东西。6.优化之二：浅谈Tasker先放一个Tasker的共享版（Tasker_4.7u3下载【提取码：5mb4】，侵删），版本不是最新的，但功能绝对够用。简单来说，Tasker可以做一个Priv上的多功能触发器，通过各种方式方法触发各种任务，具体的设置方法写出来会是一篇新的文章，这里我只提供软件介绍，后面如果有空会单独写一篇文章讲相关内容，其实可以通过Wiki查Tasker的相关内容，当然如果英语水平有限就不要看翻译的版本了，我一直怀疑那是用翻译软件翻译出来的。。。本人通过Tasker实现了如下功能：合上滑盖挂机并锁屏/到家自动开wifi/离家5分钟后关wifi/特定条件或触发下自动回复短信给未接来电。其实我认为Tasker能实现的功能非常多，只有想不到而没有做不到。7.优化之三：绿色守护与UU安全两者都是杀后台进程类的软件，从而达到省电/减少发热/系统加速等目的。具体的工作原理和软件测评网上有现成文章，我只写自己的感受：个人感觉UU安全效果好一点，但UU安全似乎并没有出支持6.0的版，最新的3.X只是在测试，有一个问题就是如果两个软件之间存在相互唤醒关系（假设用微信支付滴滴车费），如果滴滴优化而微信未优化，则无法唤醒微信。这一点不知后续版本是否会修正。而绿色守护虽然能杀掉后台进程，但是无法阻止软件间的相互唤醒，过段时间再看依然是唤醒了其他软件。8.无线充电我一直认为这是很鸡肋的功能，假设我有充电器我干嘛需要无线充电，假设我没有充电器我如何无线充电？所以一直没体验过，等什么时候搞一块充电板来体验一下再补充这段内容。9.价格及定位我的Priv购买于大约俩月之前，购买于某宝某黑莓专卖（某论坛创始人，我从9700开始就在这个店买），价格的话我认为和个人承受能力有关，不做评价。至于定位，我认为Priv首先不适合女生，因为在推出键盘后普通女生恐怕双手都不方便操作；其次不适合自拍者，Priv正面的摄像头效果实在对不起价格；第三不适合不愿意折腾的人，原因参考上述567并请自行百度“原生Android”，以上，是我能想到并不带偏见的不适宜人群。编辑于 2016-08-31 09:23Blackberry（黑莓）BlackBerry Priv黑莓使用技巧赞同 245 条评论分享喜欢收藏申请

android跨进程通信实战视频课程（加群获取优惠） hi,大家好！在做framework开发过程中相信很多朋友会有一些关于系统应用的一些权限问题，在学习过千里马相关系统内置应用相关课程后，大家也知道了系统内置应用一般放在system/app路径下，这样就不会被用户随意卸载了，但是app放在这下面具体运行起来有哪些权限和没有哪些权限就不是很清楚了。

这里刚好做一个比较全面总结： android中app主要有3个路径可以放： data/app —这个就是最为普遍的第三方应用的apk路径，安装在这里一般可以随意进行卸载 system/app --系统内置应用，这里面的app是不可以进行卸载的，所以叫做系统应用，但是系统应用的每个应用的签名却没有要求，即可以是自己应用根据情况确定，比如大部分内置应用是platform，也有shared，media等 system/priv-app —这个部分是android后来版本新加入系统特权应用路径，这里面应用和system/app一样是不可以卸载的，但是这里大家肯定会想他和system/app有什么区别么？这里其实最主要是在于二者目录的权限apk运行起来不一样

那么这里是不是有个疑问，那么是不是系统应用如果在priv-app下是不是权限就是最高？就可以自然拥有很多系统权限才可以干的是它都可以干？这个其实并不是这样的哦，权限虽和你是不是priv-app有关系，但并不是说你预制在priv-app既可以拥有系统权限。这里我们就举个例子吧：以下是一个可以修改任何app的组件是否开放（即enable状态）的一个权限，这里要求是需要声明以下权限的，普通权限如网络什么的这里声明其实就可以了，但是这是系统级别当然不是普通第三方应用就可以拥有。

android:name="android.permission.CHANGE_COMPONENT_ENABLED_STATE" />

这里看这权限要求保护级别是signature（平台签名platform）或者privileged（特权app），那么我们来尝试把app预制到priv-app里面去，具体方法：在对应mk中加入：LOCAL_PRIVILEGED_MODULE := true 这里编译后就会把apk预制到priv-app了，然后我们运行一下，发现依然会报出没有权限相关的运行错误。。。。这个是为啥明明我们就是priv-app. 这里其实我们还忽略了一个重要的，那就是还要去framework对应permission文件下进行声明权限具体方案： android-8.1.0_r1/frameworks/base/data/etc/目录下有一个 privapp-permissions-platform.xml文件，这里面有各priv-app权限声明比如我们看到musicfx就有对一个权限进行声明，所以这里我们也需要在这里对我们应用进行声明，具体就完全参考musicfx既可以，只需要改变一下包名既可以

/system/priv-app中包括 Launcher，SystemUI，SettingsProvider 等，均是系统的核心应用，这些应用能使用系统级的权限，4.4 之前的所有/system/app下的软件都能使用系统级的权限，Google 这样做是把内置到系统的应用也做个级别的区别。

放到/system/priv-app下的应用比放到/system/app下的应用可以声明获得更多的权限。在Android中每个应用都有自己的权限声明，比如要使用系统限制的权限（例如andro...
