help
|
|
MTK_PRINTK_DEBUG is used for debugging instead of gki.
|
|
First, it adds process name in log info.
|
|
|
|
Second, when one cpu exec console_unlock and log is too much,
|
|
it may be writing to console for long time.
|
|
This may Trigger HWT.
|
|
We should better detect the duration in console.
|
|
When the duration is over criteria, it will Report DB.
