Subject: [PATCH] [net] net: wwan: t7xx: Change PM_AUTOSUSPEND_MS to 5000
Date: Mon, 28 Oct 2024 15:30:15 +0800 [thread overview]
Message-ID: <20241028073015.692794-1-wojackbb@gmail.com> (raw)
From: Jack Wu <wojackbb@gmail•com>
Because optimizing the power consumption of t7XX,
change auto suspend time to 5000.
The Tests uses a script to loop through the power_state
of t7XX.
(for example: /sys/bus/pci/devices/0000\:72\:00.0/power_state)
* If Auto suspend is 20 seconds,
test script show power_state have 0~5% of the time was in D3 state
when host don't have data packet transmission.
* Changed auto suspend time to 5 seconds,
test script show power_state have 50%~80% of the time was in D3 state
when host don't have data packet transmission.
