−
Takes an input u32 enum, no output.
+
Unofficial name.
   −
The input value must be 0-1.
+
Takes an input u32 '''Mode'''. No output.
   −
This internally sends a request which is then eventually handled (if the input doesn't match state already + other state fields are valid) by configuring "pm2_sleep_ret_ext" with a global struct selected via the input value. Afterwards another func is called with input value 2.
+
'''Mode''' must be 0 or 1.
 +
 
 +
Sends command message 0x32 to the state machine.
 +
 
 +
The state machine then handles this by issuing the WLC_SET_VAR ioctl for the "pm2_sleep_ret_ext" variable. '''Mode''' is used to select between 2 sets of hardcoded parameters as follows:
 +
  struct wl_pm2_sleep_ret_ext {
 +
    u8 logic;
 +
    u8 PAD;
 +
    u16 low_ms;
 +
    u16 high_ms;
 +
    u16 rx_pkts_threshold;
 +
    u16 tx_pkts_threshold;
 +
    u16 txrx_pkts_threshold;
 +
    u32 rx_bytes_threshold;
 +
    u32 tx_bytes_threshold;
 +
    u32 txrx_bytes_threshold;
 +
  };
 +
 
 +
  wl_pm2_sleep_ret_ext args = {0};
 +
 
 +
  if (mode == 0) {
 +
    args.logic = 2;
 +
    args.low_ms = 2000;
 +
    args.high_ms = 5000;
 +
    args.rx_pkts_threshold = 10;
 +
  } else if (mode == 1) {
 +
    args.logic = 2;
 +
    args.low_ms = 200;
 +
    args.high_ms = 800;
 +
    args.rx_pkts_threshold = 10;
 +
  }
 +
Afterwards, the WLC_SET_PM ioctl is issued with the argument value 2 (PM2).
