Subject: [PATCH] Disable 8723cs power saving
|
2020-06-29 14:52:34 +00:00
|
|
|
|
|
|
|
|
The runtime power management features in the 8723cs firmware on the
|
|
|
|
|
PinePhone don't seem to work correctly. While we expect the chipset to
|
|
|
|
|
leave a low power state when it's time to send or receive data, instead
|
|
|
|
|
we get a delay of 10-20 seconds before any packets are sent.
