[其他] Acer ASPIRE 4830TG enable VT-x

使用 android studio 模擬器 會要求你安裝


安裝到一半會發生錯誤 錯誤訊息顯示 VT-X 沒有啟動

查詢 intel CPU 資料發現 i5 2410M 有支援 VT-X

但是在Acer BIOS 被閹割掉 沒有選項可以開關 VT-X

詢問Goolge 大師, 必須要刷BIOS 去開啟

有網友破解 BIOS unlock menu

鼓起勇氣刷下去 開啟 VT-x 依舊無法使用

繼續爬文 發現 AVAST 擋掉了




關掉這個選項, android 模擬器 快樂使用中!!!

android source code 有詳細說明
\dev\android\system\core\init\README.BOOTCHART


This version of init contains code to perform "bootcharting", i.e. generating log
files that can be later processed by the tools provided by www.bootchart.org.

To activate it, you need to define build 'init' with the INIT_BOOTCHART environment
variable defined to 'true', for example:

touch system/init/init.c
m INIT_BOOTCHART=true

On the emulator, use the new -bootchart <timeout> option to boot with bootcharting
activated for <timeout> seconds.

Otherwise, flash your device, and start it. Then create a file on the /data partition
with a command like the following:

adb shell 'echo $TIMEOUT > /data/bootchart-start'

Where the value of $TIMEOUT corresponds to the wanted bootcharted period in seconds;
for example, to bootchart for 2 minutes, do:

adb shell 'echo 120 > /data/bootchart-start'

Reboot your device, bootcharting will begin and stop after the period you gave.
You can also stop the bootcharting at any moment by doing the following:

adb shell 'echo 1 > /data/bootchart-stop'

Note that /data/bootchart-stop is deleted automatically by init at the end of the
bootcharting. This is not the case of /data/bootchart-start, so don't forget to delete it
when you're done collecting data:

adb shell rm /data/bootchart-start

The log files are placed in /data/bootchart/. you must run the script tools/grab-bootchart.sh
which will use ADB to retrieve them and create a bootchart.tgz file that can be used with
the bootchart parser/renderer, or even uploaded directly to the form located at:

  http://www.bootchart.org/download.html

NOTE: the bootchart.org webform doesn't seem to work at the moment, you can generate an
      image on your machine by doing the following:

         1/ download the sources from www.bootchart.org
         2/ unpack them
         3/ in the source directory, type 'ant' to build the bootchart program
         4/ type 'java -jar bootchart.jar /path/to/bootchart.tgz

technical note:

this implementation of bootcharting does use the 'bootchartd' script provided by
www.bootchart.org, but a C re-implementation that is directly compiled into our init
program.

===============
ubuntu 安裝方式

• apt-get install bootchart
