# bootio #

|

|
|
The bootio tool records I/O for processes during boot.
|
||
|
|
To use bootio kernel must be compiled with this flags:
|
||
|
|
|
||
|
|
CONFIG_TASKSTATS=y
|
||
|
|
CONFIG_TASK_DELAY_ACCT=y
|
||
|
|
CONFIG_TASK_XACCT=y
|
||
|
|
CONFIG_TASK_IO_ACCOUNTING=y
|
||
|
|
|
||
|
|
To use bootio make sure it's included in product config for the board.
|
||
|
|
Create file /data/misc/bootio/start with a command like the following:
|
||
|
|
|
||
|
|
adb shell 'echo "$TIMEOUT $SAMPLES" > /data/misc/bootio/start'
|
||
|
|
|
||
|
|
Where the value of $TIMEOUT corresponds to the desired bootio period in
|
||
|
|
seconds and $SAMPLES corresponds to the desired number of samples.
|
||
|
|
|
||
|
|
Note: /data/misc/bootio/start is not deleted automatically, so don't
|
||
|
|
forget to delete it when you're done collecting data.
|
||
|
|
|
||
|
|
To see collected logs run:
|
||
|
|
|
||
|
|
adb shell bootio -p
|
