Closed bartcubbins closed 10 months ago

  1. boot_wlan is intended only for driver probing and nothing more, it is not intended for state management from the userspace, /dev/wlan is used for this.
  2. Use /dev/wlan as driver control interface. According to the current driver, communication occurs through /dev/wlan interface and using the words ON/OFF[1]. With this change, the driver is now able to detect events that enable or disable Wi-Fi from the userspace: 
    wlan: [716:I:HDD] wlan_hdd_state_ctrl_param_write: Wifi Turning On from UI
android.hardware.wifi@1.0-service: Wifi HAL started
wlan: [716:I:HDD] wlan_hdd_state_ctrl_param_write: Wifi turning off from UI
android.hardware.wifi@1.0-service: Wifi HAL stopped
