From 62b516401f008d166b93ad2ea6f3012989b0cccb Mon Sep 17 00:00:00 2001 From: Dalton Date: Tue, 23 Jun 2020 20:54:12 -0500 Subject: [PATCH] UBPORTS SAUCE: Disable 8723cs power saving 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. --- drivers/staging/rtl8723cs-new/os_dep/linux/os_intfs.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/drivers/staging/rtl8723cs-new/os_dep/linux/os_intfs.c b/drivers/staging/rtl8723cs-new/os_dep/linux/os_intfs.c index 3e6ba0a0fd17..5bb850a4caf0 100644 --- a/drivers/staging/rtl8723cs-new/os_dep/linux/os_intfs.c +++ b/drivers/staging/rtl8723cs-new/os_dep/linux/os_intfs.c @@ -54,7 +54,12 @@ int rtw_adhoc_tx_pwr = 1; int rtw_soft_ap = 0; /* int smart_ps = 1; */ #ifdef CONFIG_POWER_SAVING - int rtw_power_mgnt = PS_MODE_MAX; + // Setting PS_MODE_ACTIVE by default keeps the power saving code in the + // driver but works around an issue where the 8723cs won't leave Leisure + // Power Saving mode without long delays.
