一波未平,一波又起
同事在windows GPIO driver 里修改 power button delay 引起了音量按键的不正常,快速按一下,颗粒度从之前的2变成了4
根据gpioint 的定义,是可以定义debounce 的值的,但是不知道是多少
https://uefi.org/specs/ACPI/6.6/19_ASL_Reference.html#gpiointterm
DebounceTimeout is an optional argument specifying the debounce wait time, in hundredths of milliseconds. The bit field name _DBT is automatically created to refer to this portion of the resource descriptor.
原来是以100ms 为单位啊
接着修改GPIO 定的按键吧,原来BIOS 里的ASL code 可以干这么多事
