Get:13 http://mirrordirector.raspbian.org/raspbian/ jessie/main blender armhf 2.72.b+dfsg0-3 [18.2 MB]

odroid 대비 port쪽이 아닌 mirror라 더 빠른건가 싶기도 하고...

raspberry pi sysbench fileio

odroid u3도 한번 해봐야지..


$ sysbench --help

Usage:

  sysbench [general-options]... --test=<test-name> [test-options]... command


General options:

  --num-threads=N            number of threads to use [1]

  --max-requests=N           limit for total number of requests [10000]

  --max-time=N               limit for total execution time in seconds [0]

  --forced-shutdown=STRING   amount of time to wait after --max-time before forcing shutdown [off]

  --thread-stack-size=SIZE   size of stack per thread [32K]

  --init-rng=[on|off]        initialize random number generator [off]

  --test=STRING              test to run

  --debug=[on|off]           print more debugging info [off]

  --validate=[on|off]        perform validation checks where possible [off]

  --help=[on|off]            print help and exit

  --version=[on|off]         print version and exit


Compiled-in tests:

  fileio - File I/O test

  cpu - CPU performance test

  memory - Memory functions speed test

  threads - Threads subsystem performance test

  mutex - Mutex performance test

  oltp - OLTP test


Commands: prepare run cleanup help version


See 'sysbench --test=<name> help' for a list of options for each test.

fdisk로 파일명을 넣어주고 나서 offset 이용해서 마운트하면 되는구나...


$ fdisk -l whatever.img

Device         Boot     Start       End  Blocks  Id System

whatever.img1            8192    122879   57344   c W95 FAT32 (LBA)

whatever.img2          122880   5785599 2831360  83 Linux


$ mount -v -o offset=4194304 -t vfat whatever.img /mnt/img/one

$ mount -v -o offset=62914560 -t ext4 whatever.img /mnt/img/two


1st partition 512 * 8192 = 4194304

What is LCDproc?


LCDproc is a client/server suite including drivers for all kinds of nifty LCD displays.


The server LCDd makes it possible to display text and other data on an LCD display. As well LCDd can handle certain input devices.


Support for devices is added by drivers. We distinguish between output and input drivers. LCDd currently supports only one single output driver, which may at the same time handle input. Nevertheless several input (only) drivers are supported.


Currently there are drivers for several serial devices: Matrix Orbital, Crystal Fontz, Bayrad, LB216, LCDM001 (kernelconcepts.de), Wirz-SLI and PIC-an-LCD; and some devices connected to the LPT port: HD44780, STV5730, T6963, SED1520 and SED1330. There are input (only) drivers for LIRC and joysticks.


Clients can connect to LCDd through common TCP sockets.


Various clients are available. The main client lcdproc, which is shipped with the LCDproc distribution, can display things like CPU load, system load, memory usage, uptime, and a lot more.


[링크 : http://lcdproc.sourceforge.net/docs/current-user.html]


LPT 포트가 있어야 설정이 가능할 것 같은 느낌?
FTDI USB to Serial로도 가능은 하지만 흐음.. 아무튼 라즈베리에 적용하는게 쉽지는 않을 기분
