+What:           /sys/kernel/uids/<uid>/cpu_shares
+Date:           December 2007
+Contact:        Dhaval Giani <dhaval@linux.vnet.ibm.com>
+                Srivatsa Vaddagiri <vatsa@linux.vnet.ibm.com>
+Description:
+                The /sys/kernel/uids/<uid>/cpu_shares tunable is used
+                to set the cpu bandwidth a user is allowed. This is a
+                propotional value. What that means is that if there
+                are two users logged in, each with an equal number of
+                shares, then they will get equal CPU bandwidth. Another
+                example would be, if User A has shares = 1024 and user
+                B has shares = 2048, User B will get twice the CPU
+                bandwidth user A will. For more details refer

 A Driver driver (yes, this sounds ridiculous, sorry) contains the general
 code to access some type of device. Each detected device gets its own
 data in the Client structure. Usually, Driver and Client are more closely
 integrated than Algorithm and Adapter.
 
-For a given configuration, you will need a driver for your I2C bus (usually

+For a given configuration, you will need a driver for your I2C bus, and
+drivers for your I2C devices (usually one driver for each device).
 
 At this time, Linux only operates I2C (or SMBus) in master mode; you can't
 use these APIs to make a Linux system behave as a slave/device, either to
 speak a custom protocol or to emulate some other device.

+않는(stable) 커� �터페�스를 갖지 않는지를 설명하기 위해 쓰여졌다.
+� 문서는 커�과 유저공간 사�� �터페�스가 아니� 커� 내부�
+�터페�스들� 설명하고 있다는 것� 유�하�. 커�과 유저공간 사��
+�터페�스는 �용프로그램� 사용하는 syscall �터페�스�다. 그 �터페�스는

+
+소개
+----
+
+커� 내부� �터페�스가 바뀌는 것� 걱정하며 커� 드��버를 작성하고
+싶어하는 사람� 정� ��한 사람�다. 세�� 대다수� 사람들� � �터페�스를
+보지못할 것�며 전혀 걱정하지� 않는다.
+
+먼저, 나는 closed 소스, hidden 소스, binary blobs, 소스 wrappers, �는 GPL로
+배��었지만 소스 코드를 갖고 있지 않� 커� 드��버들� 설명하는 어떤 다른
+용어들� 관한 어떤 법�� 문제� 관해서는 언급하지 않� 것�다. 어떤 법��
+질문들� 가지고 있다면 변호사와 연�하�. 나는 프로그래머�므로 여기서 기술��
+문제들만� 설명하려고 한다. (법�� 문제를 경시하는 것� 아니다. 그런 문제들�
+엄연히 현실� 있고 여러분들� 항� 그 문제들� ��하고 있� 필요는 있다.)
+
+�, �가지� 주요 주제가 있다. 바�너리 커� �터페�스들과 변하지 않는
+커� 소스 �터페�들. 그것들� 서로 �존성� 가지고 있지만 바�너리
+문제를 먼저 풀고 넘어갈 것�다.
+
+
+
+바�너리 커� �터페�스
+------------------------
+우리가 변하지 않는 커� 소스 �터페�스를 가지고 있다고 가정하�. 그러면
+바�너리 �터페�스 �한 �연�으로 변하지 않�까? 틀렸다. 리눅스 커��
+관한 다� 사실들� ��해보�.
+   - 여러분들� 사용하는 C 컴파�러� 버젼� 따� 다른 커� �료 구조들�
+     다른 alignmnet들� 갖게 �것�고 다른 방법으로(함수들� inline으로
+     했��, 아니�) 다른 함수들� �함하는 것� 가능한다. 중요한 것�
+     개별�� 함수 구성� 아니� �료 구조 패딩� 달�진다는 ��다.
+   - 여러분� 선�한 커� 빌드 옵션� 따�서 커�� 다양한 것들� 가정할
+     수 있다.
+      - 다른 구조체들� 다른 필드들� �함할 수 있다.
+      - 몇몇 함수들� 전혀 구현�지 않� 수� 있다(즉, 몇몇 lock들�
+        non-SMP 빌드�서는 사�져 버릴수� 있다).
+      - 커�내� 메모리는 build optoin들� 따� 다른 방법으로 align�수
+        있다.
+      - 리눅스는 많� 다양한 프로세서 아키���서 실행�다. 한 아키���
+        바�너리 드��버를 다른 아키���서 정��으로 실행시킬 방법�
+        없다.
+
+커�� 빌드했� C 컴파�러와 정확하게 같� 것� 사용하고 정확하게 같�
+커� 구성(configuration)� 사용하여 여러분들� 모듈� 빌드하면 간단히
+많� 문제들� 해결할 수 있다. �렇게 하는 것� 여러분들� 하나� 리눅스
+배��� 하나� 배� 버젼� 위한 모듈만� 제공한다면 별� 아� 것�다.
+그러나 �기 다른 리눅스 배��마다 한번씩 빌드하는 수를 � 리눅스 배��마다
+제공하는 다른 릴리즈� 수와 곱하게 �면 �번�는 � 릴리즈들� 다른 빌드
+옵션� 악몽과 마주하게  것�다. �한 � 리눅스 배��들� 다른 하드웨어
+종류�(다른 프로세서 타입과 다른 옵션들) 맞춰져 있는 많� 다른 커�들�
+배�한다. 그러므로 한번� 배��서조차 여러분들� 모듈� 여러 버젼�
+만들 필요가 있다.
+
+나를 믿어�. 여러분들� �러한 종류� 배�를 지�하려고 시�한다면 시간�
+지나면 미칠지경� � 것�다. 난 �러한 것� 오래전� 아주 어렵게 배웠다...
+
+
+
+변하지않는 커� 소스 �터페�스들
+---------------------------------
+
+리눅스 커� 드��버를 계�해서 메� 커� 트리� 반�하지 않고
+유지보수하려고 하는 사름들과 � 문제를 논�하게 �면 훨씬 �
+"논란� 여지가 많�" 주제가 � 것�다.
+
+리눅스 커� 개발� �임없� 빠른 ��로 �루어지고 있으며 결코
+�슨해진 �� 없다. 커� 개발�들� 현재 �터페�스들�서 버그를
+발견하거나 무엇�가 할수 있는 � 좋� 방법� 찾게 �었다고 하�.
+그들� 발견한 것� 실행한다면 아마� � 잘 �작하�� 현재 �터페�스들�
+수정하게 � 것�다. 그들� 그런 �� 하게�면 함수 �름들� 변하게 �고,
+구조체들� 늘어나거나 줄어들게 �고, 함수 파�미터들� 재작업� 것�다.
+�러한 �� 발��면 커� 내� � �터페�스를 사용했� �스턴스들� �시�
+수정� 것�며 �러한 과정� 모든 것� 계�해서 올바르게 �작할 것��는
+것� 보장한다.
+
+�러한 것� 한 예로�, 커� 내부� USB �터페�스들� � 서브시스템�
+�긴 �후로 �어� 3번� 다른 재작업� 겪었다. � 재작업들� 많� 다른
+문제들� 풀었다.
+   - ��터 스트림들� �기�� 모��서 비�기�� 모�로� 변화. �것�
+     많� 드��버들� 복잡성� 줄�고 처리량� 향�시켜 현재는 거� 모든
+     USB 장치들� 거� 최대 ��로 실행�고 있다.
+   - USB 드��버가 USB 코어로부터 ��터 패킷들� 할당받로� 한 변경으로
+     �해서 지금� 모든 드��버들� 많� 문서화� �드�� 수정하기 위하여
+     USB 코어�게 � 많� 정보를 제공해야만 한다.
+
+�것� 오랫�안 �신� 오래� USB �터페�스들� 유지해야 하는 closed 운�체제들과는
+완전히 반대�는 것�다. closed� 운�체제들� 새로운 개발�들�게 우연히 낡�
+�터페�스를 사용하게 할 기회를 주게�며, �절하지 못한 방법으로 처리하게 �어
+운�체제� 안정성� 해치는 문제를 야기하게 �다.
+
+� �가지� 예들 모�, 모든 개발�들� 꼭 �루어져야 하는 중요한 변화들��고
+��를 하였고 비�� �� 고통으로 변경�어졌다. 리눅스가 변하지 않는 소스
+�터페�스를 고집한다면, 새로운 �터페�스가 만들어지게 �며 반면 기존� 오래�
+것들, 그리고 깨진 것들� 계�해서 유지�어야 하며 �러한 �들� USB 개발�들�게
+� 다른 �거리를 주게 �다. 모든 리눅스 USB 개발�들�게 �신� 그들� 업무를
+마친 후 시간� 투�하여 아무 �� 없는 무료 봉사를 해달�고 하는 것� 가능성�
+�박한 ��다.
+
+보안 문제 역시 리눅스�게는 매우 중요하다. 보안 문제가 발견�면 그것�
+매우 짧� 시간 안� 수정�다. 보안 문제는 그 문제를 해결하기 위하여
+여러번 내부 커� �터페�스들� 재작업하게 만들었다. �러한 문제가
+발�하였� 때 그 �터페�스들� 사용하는 모든 드��버들� �시�
+수정�어 보안 문제가 앞으로 갑작스럽게 �기지는 않� 것��는 것�
+보장한다. 내부 �터페�스들� 변경� 허��지 않으면 �러한 종류� 보안
+문제를 수정하고 그것� 다시 발�하지 않� 것��고 보장하는 것� 가능하지
+않� 것�다.
+
+커� �터페�스들� 계�해서 정리�고 있다. 현재 �터페�스를 사용하는
+사람� 한명� 없다면 그것� 삭제�다. �것� 커�� 가능한한 가장 작게
+유지�며 존재하는 모든 가능성� 있는 �터페�스들� 테스트�다는 것�
+보장한다(사용�지 않는 �터페�스들� 유효성 검�� 하기가 거� 불가능하다).
+
+
+무엇� 해야 하나
+---------------
+�, 여러분� 메� 커� 트리� 있지 않� 리눅스 커� 드��버를 가지고
+있다면 여러분� 즉, 개발�는 무엇� 해야 하나? 모든 배��마다 다른
+커� 버젼� 위한 바�너리 드��버를 배�하는 것� 악몽�며 계�해서
+변하고 있는 커� �터페�스들� 맞처 유지보수하려고 시�하는 것� 힘든
+��다.
+
+간단하다. 여러분� 커� 드��버를 메� 커� 트리� 반�하�(우리는 여기서
+GPL� 따르는 배� 드��버� 관해 얘기하고 있다는 것� �기하�. 여러분�
+코드가 �러한 분류� 해당�지 않는다면 행운� 빈다. 여러분 스스로 어떻게든
+해야만 한다). 여러분� 드��버가 트리� 있게�면 커� �터페�스가
+변경���� 가장 먼저 커�� 변경� 가했� 사람� �해서 수정� 것�다.
+�것� 여러분� 드��버가 여러분� 별다른 노력없� 항� 빌드가 가능하며
+�작하는 것� 보장한다.
+
+메� 커� 트리� 여러분� 드��버를 반�하면 얻게 �는 장�들� 다�과 같다.
+   - 관리� 드는 비용(�래 개발��)� 줄어줄면서 드��버� 질� 향�� 것�다.
+   - 다른 개발�들� 여러분� 드��버� 기능들� 추가 할 것�다.
+   - 다른 사람들� 여러분� 드��버� 버그를 발견하고 수정할 것�다.
+   - 다른 사람들� 여러분� 드��버� 개선�� 찾� 줄 것�다.
+   - 외부 �터페�스 변경으로 �해 여러분� 드��버� 수정� 필요하다면 다른
+     사람들� 드��버를 업��트할 것�다.
+   - 여러분� 드��버는 별다른 노력 없� 모든 리눅스 배���  ���으로
+     추가� 것�다.
+
+리눅스는 다른 운� 체제보다 "쉽게 쓸수 있는(out of the box)" 많� 다른 장치들�
+지�하고 어떤 다른 운� 체제보다 다양한 아키��위�서 �러한 장치들� 지�하기 때문�
+�러한 �명� 개발 모�� 틀림없� 바로 가고 있는 것�다.

-                Parallel link cable for Texas Instruments handhelds

-Author: Romain Lievin
-Homepage: http://lpg.ticalc.org/prj_tidev/index.html

-
-INTRODUCTION:
-
-This is a driver for the very common home-made parallel link cable, a cable 
-designed for connecting TI8x/9x graphing calculators (handhelds) to a computer
-or workstation (Alpha, Sparc). Given that driver is built on parport, the 
-parallel port abstraction layer, this driver is architecture-independent.
-
-It can also be used with another device plugged on the same port (such as a
-ZIP drive). I have a 100MB ZIP and both of them work fine!
-
-If you need more information, please visit the 'TI drivers' homepage at the URL
-above.
-
-WHAT YOU NEED:
-
-A TI calculator and a program capable of communicating with your calculator.
-
-TiLP will work for sure (since I am its developer!). yal92 may be able to use
-it by changing tidev for tipar (may require some hacking...).
-
-HOW TO USE IT:
-
-You must have first compiled parport support (CONFIG_PARPORT_DEV): either 
-compiled in your kernel, either as a module. 
-
-Next, (as root):
-
-       modprobe parport
-       modprobe tipar
-
-If it is not already there (it usually is), create the device:
-
-       mknod /dev/tipar0 c 115 0
-       mknod /dev/tipar1 c 115 1
-       mknod /dev/tipar2 c 115 2
-
-You will have to set permissions on this device to allow you to read/write
-from it:
-
-       chmod 666 /dev/tipar[0..2]
-       
-Now you are ready to run a linking program such as TiLP. Be sure to configure 
-it properly (RTFM).
-       
-MODULE PARAMETERS:
-
-  You can set these with:  modprobe tipar NAME=VALUE
-  There is currently no way to set these on a per-cable basis.
-
-  NAME: timeout
-  TYPE: integer
-  DEFAULT: 15
-  DESC: Timeout value in tenth of seconds. If no data is available once this 
-        time has expired then the driver will return with a timeout error.
-
-  NAME: delay
-  TYPE: integer
-  DEFAULT: 10
-  DESC: Inter-bit delay in micro-seconds. A lower value gives an higher data
-        rate but makes transmission less reliable.
-
-These parameters can be changed at run time by any program via ioctl(2) calls 
-as listed in ./include/linux/ticable.h.
-
-Rather than write 50 pages describing the ioctl() and so on, it is
-perhaps more useful you look at ticables library (dev_link.c) that demonstrates
-how to use them, and demonstrates the features of the driver. This is
-probably a lot more useful to people interested in writing applications
-that will be using this driver.
-
-QUIRKS/BUGS:
-
-None.
-
-HOW TO CONTACT US:
-
-You can email me at roms@lpg.ticalc.org. Please prefix the subject line
-with "TIPAR: " so that I am certain to notice your message.
-You can also mail JB at jb@jblache.org. He packaged these drivers for Debian.
-
-CREDITS:
-
-The code is based on tidev.c & parport.c.
-The driver has been developed independently of Texas Instruments.

-          If you own a Texas Instruments graphing calculator and use a
-          parallel link cable, then you might be interested in this driver.
-
-          If you enable this driver, you will be able to communicate with
-          your calculator through a set of device nodes under /dev. The
-          main advantage of this driver is that you don't have to be root
-          to use this precise link cable (depending on the permissions on
-          the device nodes, though).
-
-          To compile this driver as a module, choose M here: the
-          module will be called tipar.
-
-          If you don't know what a parallel link cable is or what a Texas
-          Instruments graphing calculator is, then you probably don't need this
-          driver.

- *      tipar=timeout,delay       (set timeout and delay)
- *
- * If the driver is loaded as a module, similar functionality is available
