+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
+		Documentation/sched-design-CFS.txt

+
+� 문서는 리눅스가 왜 바�너리 커� �터페�스를 갖지 않는지, 왜 변하지
+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

+있다. � �터페�스는 사용�와 �용프로그램 개발�들� 변하지 않� 것��고

+----

+그렇지 않으며 심지어는 그것� 알아채지 못한다. 여러분� �하는 것�

+리눅스를 강건하고, 안정��며, 성숙한 운�체제로 만들어 놓�으로�
+여러분들로 하여금 바로 리눅스를 사용하게 만드는 �유�다.
+
+
+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

-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.
