Los Angeles

A city of southern California on the Pacific Ocean in a widespread metropolitan area. The so-called City of the Angels was founded by the Spanish in 1781 and served several times as a colonial capital. Its real growth began after the coming of the railroads in the 1870's and 1880's and the discovery of oil in the 1890's. Today it is a major shipping, manufacturing, communications, financial, and distribution center noted for its entertainment industry. Population, 3,485,398.

Like Las Vegas, the allure of L.A. -- for better or for worse -- is undeniable. Los Angelenos know their city will never have the sophisticated style of Paris or the historical riches of London, but they cheerfully lay claim to living in the most entertaining city in the United States, if not the world. It really is warm and sunny most days of the year, movie stars actually do live and dine among the commoners, and you can't swing a cellphone without hitting a roller-blading blonde at the beach.

This part of the L.A. mystique -- however exaggerated it may be -- truly does exist, and it's not hard to find. In fact, it's fitting that L.A. is home to the world's first amusement park because it regularly feels like one, as the line between fantasy and reality is often obscured. From the unattainable, anachronistic glamour of Beverly Hills to the vibrant street energy of the Venice Boardwalk, each of the city's diverse neighborhoods is like a mini?theme park, offering its own kind of unique adventure. Drive down Sunset Boulevard and you'll see what I mean: The billboards are racier, the fashions trendier, the cars fancier, the bodies sexier, the sun brighter, and the energy higher than any place you've ever been. Darlin', you ain't in Kansas anymore -- you're in La-La Land. Let's go play.

嵌入式android源码架构：uboot+linux kernel+android（包含文件系统，虚拟机，UI）

嵌入式linux：这是大部分人认识的linux uboot+linux kernel+文件系统+QT（UI），

当然两者的linux 内核因为上层UI的不同会稍有差别，不过还是非常接近的，做过linux的人可以无缝切换到android底层开发，所以大家说的学习android系统，其实最重要的就是学习linux驱动，再加一下android下的专门的HAL，JNI，java等等，不过大公司android相关部分也是专门的人做的了。

甚至连QT都不用了，因为linux很多设备都是没有UI的，所以要来干啥？直接无界面，照样是嵌入式linux。

现在大家说的什么嵌入式debian，ubuntu，其实也是站在linux巨人的肩膀上，其实都不算是linux的分支，只算是linux的延伸，小变化而已。看到这里大家知道嵌入式linux的强大了吧，反正是比wince 强大N倍啊。

O(∩_∩)O~，所以啊，学习嵌入式android，其实底下就是学习uboot，linux内核啊，不会搞这些就像搞应用一样，所以大家以为android就是java，是非常片面的。

以前老的，说了一下区别，可以参考一下

ARCH -- 这是Android修改了arch/arm下面的一些文件：

arch/arm:

Chg: arch/arm/kernel/entry-armv.S

Chg: arch/arm/kernel/module.c

Chg: arch/arm/kernel/process.c

Chg: arch/arm/kernel/ptrace.c

Chg: arch/arm/vfp/vfphw.S

Chg: arch/arm/vfp/vfpmodule.c

Goldfish -- 这是Android为了模拟器所开发的一个虚拟硬件平台。Goldfish执行arm926T指令（在2.6.29中，goldfish也支持ATMv7指令），但是在实际的设备中，该虚拟平台的文件不会被编译。

New: arch/arm/mach-goldfish/timer.c

YAFFS2 -- 和PC把文件存储在硬盘上不一样， 移动设备一般把Flash作为存储设备。尤其是NAND flash应用非常广泛（绝大多数手机用的都是NAND flash，三星的一些手机使用的是OneNAND）。NAND flash具有低成本和高密度的优点。

YAFFS2 是“Yet Another Flash File System, 2nd edition" 的简称。 它提供在Linux内核和NAND flash设备 之前高效率的接口。 YAFFS2并没有包含在标准的Linux内核中， Google把它添加到了Android的kernel

Bluetooth -- Google为Bluetooth打上了patch，fix了一些Bluetooth的bug

drivers/bluetooth:

Chg: drivers/bluetooth/bfusb.c

Chg: drivers/bluetooth/bt3c_cs.c

Chg: drivers/bluetooth/btusb.c

Chg: drivers/bluetooth/hci_h4.c

Chg: drivers/bluetooth/hci_ll.c

Scheduler -- 对于Scheduler的改变非常小，我对它并没有去研究。

Chg: kernel/sched.c

New Android Functionality -- 除了fix一些bug以及其他一些小的更改，Android增加了一些新的功能，介绍如下：

IPC Binder -- The IPC Binder is an Inter-Process Communication (IPC) mechanism. It allows processes to provide services to other processes via a set of higher-level APIs than are available in standard Linux. An Internet search indicated that the Binder concept originated at Be, Inc., and then made its way into Palm's software, before Google wrote a new Binder for Android.

New: drivers/staging/android/binder.c

Low Memory Killer -- Android adds a low-memory killer that, each time it's called, scans the list of running Linux processes, and kills one. It was not clear in our cursory examination why Android adds a low-memory killer on top of the already existing one in the standard Linux kernel.

New: drivers/staging/android/lowmemorykiller.c

Ashmem -- Ashmem is an Anonymous SHared MEMory system that adds interfaces so processes can share named blocks of memory. As an example, the system could use Ashmem to store icons, which multiple processes could then access when drawing their UI. The advantage of Ashmem over traditional Linux shared memory is that it provides a means for the kernel to reclaim these shared memory blocks if they are not currently in use. If a process then tries to access a shared memory block the kernel has freed, it will receive an error, and will then need to reallocate the block and reload the data.

New: mm/ashmem.c

RAM Console and Log Device -- To aid in debugging, Android adds the ability to store kernel log messages to a RAM buffer. Additionally, Android adds a separate logging module so that user processes can read and write user log messages.

New: drivers/staging/android/ram_console.c

Android Debug Bridge -- Debugging embedded devices can best be described as challenging. To make debugging easier, Google created the Android Debug Bridge (ADB), which is a protocol that runs over a USB link between a hardware device running Android and a developer writing applications on a desktop PC.

drivers/usb/gadget:

New: drivers/usb/gadget/android.c

Chg: drivers/usb/gadget/composite.c

Chg: drivers/usb/gadget/f_acm.c

New: drivers/usb/gadget/f_acm.h

New: drivers/usb/gadget/f_adb.c

New: drivers/usb/gadget/f_adb.h

New: drivers/usb/gadget/f_mass_storage.c

New: drivers/usb/gadget/f_mass_storage.h

Android also adds a new real-time clock, switch support, and timed GPIO support. We list the impacted files for these new modules at the end of this document.

Power Management -- Power management is one of the most difficult pieces to get right in mobile devices, so we split it out into a group separate from the other pieces. It's interesting to note that Google added a new power management system to Linux, rather than reuse what already existed. We list the impacted files at the end of this document.

kernel/power:

New: kernel/power/consoleearlysuspend.c

New: kernel/power/earlysuspend.c

New: kernel/power/fbearlysuspend.c

Chg: kernel/power/main.c

Chg: kernel/power/power.h

Chg: kernel/power/process.c

New: kernel/power/userwakelock.c

New: kernel/power/wakelock.c

Miscellaneous Changes -- In addition to the above, we found a number of changes that could best be described as, 'Miscellaneous.' Among other things, these changes include additional debugging support, keypad light controls, and management of TCP networking
