집에서 어머님이 심심해 하시는 것 같아 애완 동물 하나 기르면 어떨까 생각하고 있었습니다.
강아지랑 애완 토끼중 고민하다가 토끼 한마리 분양 받았네요^^
품종은 롭이어구요 다른 토끼들과는 다르게 귀가 쳐진것이 특징입니다 (완전 귀여워요~ㅎ)
손에 침 뭍혀서 세수하고 귀닦을땐 너무 귀여워서 어쩔줄 모르겠네요ㅎㅎ 웬 주책인지ㅋ
울집 토끼 토토를 소개합니다^^
With the introduction of the tickless kernel and PowerTop it has become possible to save significant amounts of power by reducing the number of times per second that the CPU has to do work. This in turn allows the CPU to sleep for longer periods of time and spend more time in deeper C-states.
However, most people do not know about powertop and, frankly, should not have to tweak their own system's power usage. Linux should save power by default, whenever it is possible to do so.
The concept of this project is simple:
Install a recent kernel on your system.
Run powertop.
Reduce the number of wakeups coming from the kernel.
Saving 3 Watts of power on millions of computers can make quite a difference.
Strategies
Enable power saving in device drivers by default. When power saving was introduced, it was often done as an optional module parameter to a device driver. Today it still is, even though it could probably be enabled by default now.
Make wakeups in the kernel all happen simultaneously, by rounding longer sleeps up to the next whole second. This is done with the round_jiffies() macro.
Areas to work on
Sound drivers. Can power saving be enabled by default?
Wireless drivers.
USB and SATA controllers.
Look at timers in the kernel. Which ones can rounded up to the next whole second with round_jiffies?
제 스스로 학습하기 위한 목적도 있고 위 사이트의 컨텐츠 내용을 기반으로 블로그에 포스팅을 하고 문서 번역등의 일을 할 계획입니다. 모쪼록 관심있으신 분들도 같이 참여해서 서로 발전했으면 좋겠습니다.^^
