The actual +power consumption difference is inconsequential on desktops and laptops, +while the performance difference is monumental. Latencies of 20+ ms are no +longer observed after this change, and the connection is much more stable. + +Signed-off-by: Sultan Alsawaf <sultan@kerneltoast.com> +--- + drivers/net/wireless/mediatek/mt76/mt7921/init.c | 9 ++------- + 1 file changed, 2 insertions(+), 7 deletions(-) + +diff --git a/drivers/net/wireless/mediatek/mt76/mt7921/init.c b/drivers/net/wireless/mediatek/mt76/mt7921/init.c +index 91fc41922d95..cfa0bb51004d 100644 +--- a/drivers/net/wireless/mediatek/mt76/mt7921/init.c ++++ b/drivers/net/wireless/mediatek/mt76/mt7921/init.c +@@ -67,7 +67,8 @@ + + wiphy->iface_combinations = if_comb; + wiphy->flags &= ~(WIPHY_FLAG_IBSS_RSN | WIPHY_FLAG_4ADDR_AP | +- WIPHY_FLAG_4ADDR_STATION); ++ WIPHY_FLAG_4ADDR_STATION | ++ WIPHY_FLAG_PS_ON_BY_DEFAULT); + wiphy->interface_modes = BIT(NL80211_IFTYPE_STATION) | + BIT(NL80211_IFTYPE_AP); + wiphy->n_iface_combinations = ARRAY_SIZE(if_comb); +@@ -266,12 +267,6 @@ int mt7921_register_device(struct mt7921_dev *dev) + dev->pm.idle_timeout = MT7921_PM_TIMEOUT; + dev->pm.stats.last_wake_event = jiffies; + dev->pm.stats.last_doze_event = jiffies; +- if (!mt76_is_usb(&dev->mt76)) { +- dev->pm.enable_user = true; +- dev->pm.enable = true; +- dev->pm.ds_enable_user = true; +- dev->pm.ds_enable = true; +- } + + if (!mt76_is_mmio(&dev->mt76)) + hw->extra_tx_headroom += MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE; |
